▼ Les progrès en biotechno]ogie ont permis le développement d’outils pour le transfert de gène intégratif en transgénèse, bioproduction et thérapie génique. Cependant, trois challenges majeurs doivent être relevés pour garantir un système sécurisé : l’innocuité et l’efficacité du transfert, l’intégration ciblée et contrôlée dans le génome, le niveau et la durée d’expression du transgène au cours du temps. Dans ce but, mes travaux de thèse ont consisté à tester des solutions pour améliorer la biosécurité du transposon piggyBac qui nécessite un plasmide porteur du gène d’intérêt à insérer dans le génome et une source de transposase catalysant la réaction d’intégration du transgène. Une des stratégies de ma thèse repose sur l’apport de la source de transposase sous forme d’ARN messager au lieu d’ADN afin d’améliorer la stabilité de l’intégration et de réduire les effets génotoxiques en limitant la transposase dans les cellules. Pour la première fois, la biodisponibilité de l’ARNm de la transposase et les conditions optimales d’utilisation en cellules humaines ont été déterminées pour augmenter la biosêcurité du système. Le second objectif de mes travaux consiste à améliorer l’expression du transgène en ajoutant des insulateurs connus pour s’opposer à l’extinction de l’expression des gênes. En termes de biosécurité, cette stratégie permet de réduire le nombre de copies du transgène nécessaires pour obtenir une expression suffisante. Deux candidats ont été identifiés pour améliorer l’expression du transgène. La combinaison des approches ARNrn et insulateurs est prometteuse pour sécuriser le transfert de gène médié par piggyBac et pour maintenir l’expression du gène d’intérêt.
Advances in biotechnology have enabled the development of tools for gene transfer applicable to transgenesis, bioproduction and gene therapy. But, 3 major challenges must be met to ensure a secure system: the safety and effectiveness of the transfer. the targeted and controlled integration into the genome. and the level of transgene expression over time. In this aim, my thesis project was to validate solutions to improve the biosafety of the piggyBac transposon, which requires a plasmid carrying the gene of interest to be inserted in the genome, and a source of transposase which catalyzes the transgene integration. One approach of my thesis work is to deliver the source of piggyBac transposase as an mRNA molecule instead of DNA. This strategy aims to improve the stability of the integration and reduce the genotoxic effects by limiting the transposase in the cells. For the 1st time, the bioavailability of the transposase rnRNA and the optimal conditions for its use in human cells were determined to increase the biosafety of the transposon system. The 2nd objective ofmy project is to improve the expression of the transgene by adding insulators known to counteract the transgene silencing. This strategy reduces the number of integrations required ta get a sufficient expression of the transgene and thus, improve biosecurity. Two candidates have been…

▼ Transposable elements (TEs) are mobile DNA sequences, often called “jumping genes”
because of their ability to replicate to new genomic locations. As a result, TEs make
up a significant proportion of the eukaryotic genomes we see today. Growing evidence
suggests that TEs are catalysts of genomic change. TE insertions into regulatory regions
can lead to new genes, or they can disrupt host sequences and serve as substrates for
homologous recombination, generating DNA rearrangements. At the RNA level, TEs can
carry transcription factor binding sites, causing alternative splicing and thus impacting
gene expression. Some TEs are even capable of jumping between different genomes,
using viruses or parasitic insects as
transfer vectors. Originally viewed as “junk” DNA,
TEs are now recognised as powerful drivers of genome evolution.
However, there are numerous computational challenges to accurately detecting and
characterising TEs in genomic data. Many existing tools and pipelines are designed
to explicitly remove repetitive, non-unique sequences. Likewise, TE annotation software
relies heavily on the use of query sequences and reference databases. This restricts the
ability to find new types of TEs (or mutated forms of known TEs), mainly suited to the
analysis of model organisms such as human and mouse.
In this thesis, I describe an ab initio pipeline for identifying species-specific repeats
and segmental duplications with high sensitivity and accuracy. I consider a repeat in
the truest sense of the word: any sequence that appears more than once in the genome.
Using eight representative species from each branch of amniote evolution, I use this
novel method to portray the remarkable diversity of TEs across species and trace different
repeats to their families and consensus sequences.
Reptiles are particularly renowned for their unusual TE dynamics. In Chapter 3, I
investigate TE evolution in the tuatara genome: a New Zealand reptile. The tuatara
is the only surviving member of its order, which flourished around 200 million years ago.
Its most recent common ancestor with any other extant group is the lizards and snakes.
The tuatara is therefore of great interest to evolutionary geneticists.
In most reptiles, CR1 repeats make up the dominant TE class. My results indicate that the
tuatara genome is distinct from other reptiles because the two most dominant TE families
are L2 and MIR elements. Furthermore, I describe a likely
transfer of L2 elements between tuatara and monotremes (platypus and echidna), potentially explaining the predominance
of L2s in the tuatara genome.
In Chapter 4, I extend my TE analysis to consider
gene expression in six species. Due
to the prevalence of TEs in the genome, I used a bootstrap approach to minimize the
co-occurrence of multiple TE types in one
gene. My results show that species-specific
associations of TEs with
gene expression support a role for TEs in speciation/response to
selection by species.
Altogether, this thesis presents novel and ab initio…

▼ In this thesis I have firstly applied
gene transfer
technologies to the redirection of T cell specificity, by trying to overcome
limitations related to non-viral
gene transfer systems. In the second part of
my PhD work, I focused on genetic screens, which, I applied to understanding
molecular mechanisms of escape from T cell attack and to reveal mechanisms of
PD-L1 regulation.
The work presented in this thesis may on the one hand facilitate the clinical
application of non-viral-based
gene transfer systems in T cells. On the other
hand, the more fundamental discoveries related to IFN-γ-
mediated tumor cell
killing and PD-L1 regulation may help to further understand resistance toward
immunotherapies and how to overcome them.

▼ Cystic fibrosis (CF) is the most common autosomal recessive genetic disease in
Caucasian populations. CF affects multiple organ systems including pancreas, liver,
intestines, sweat glands, and male reproductive organs, however the leading cause of
morbidity and mortality in CF patients is chronic lung disease. CF is caused by a
mutant cystic fibrosis transmembrane conductance regulator (CFTR)
gene which leads
to chloride (Cl-) and bicarbonate (HCO3-) anion dysregulation at the airway surface.
Without adequate anion exchange, thick, viscous mucus accumulates at the airway
surface allowing bacterial colonization to occur. Complementing CFTR in the
appropriate airway cells restores the anion channel activity in CFTR-deficient
cells. The ultimate goal for CF
gene therapy is to design an integrating vector that
would lead to persistent and efficient expression of CFTR in the airways.
Performing
gene therapy experiments is dependent upon a relevant animal model. The CF
pig is a large animal model similar in size, anatomy, and physiology to humans.
Importantly, the CF pig recapitulates human lung disease. From the CF pig, we have
learned much about CF lung disease and have developed relevant assays to measure
anion channel correction. We have learned that loss of CFTR leads to a decreased
airway surface ASL pH, bacterial killing ability, and increased mucus viscosity.
Standardized assays have been developed to evaluate the change in current by Ussing
chambers, ASL pH, bacterial killing in vivo and ASL pH and viscosity on primary
airway cultures in vitro. Ultimately, these metrics allow us to make conclusions
about the efficiency of CFTR restoration.
Viral vectors are promising candidates for CF
gene therapy. Viral vectors such as
adenovirus (Ad), adeno-associated virus (AAV), and pseudotyped lentiviral vectors
such as feline immunodeficiency virus (FIV) or human immunodeficiency virus (HIV)
can efficiently transduce airway cells and express CFTR. Ad and AAV have both been
tested in CF clinical trials, but CFTR expression was transient, if detected at all.
Understanding vector biology and overcoming barriers in the lung have allowed us to
improve vector delivery to the airways. However, the next major hurdle was achieving
persistent expression. Ad and AAV are both transiently expressing vectors, and
vector readministration is implausible due to the presence of neutralizing
antibodies that develop against the vector. Creating a hybrid nonviral/viral vector
in which the integrating nonviral piggyBac
transposon system is delivered…

▼ Receptor-
mediated gene transfer is an attractive
method for therapeutically correcting human genetic diseases since
it permits the targeting of DNA to cellular receptors in specific
tissues of adult animals. The
gene delivery vehicle is composed of
the DNA of interest, a DNA binding moiety (i.e., poly(L-lysine))
and a ligand for the target receptor. Genes introduced by this
technique have been shown to be expressed in the target tissue for
varying periods. However, to be useful for
gene therapy, it is
critical that both the chemical properties and physical
interactions of the reagents involved in the design of the DNA
delivery vehicle (DNA/ligand complex) be rigorously characterized.
To obtain a DNA/ligand complex suitable for in vivo
gene transfer,
I have developed a multi-step protocol for the interaction of
poly(L-lysine) with DNA in solution. I demonstrate here that the
slow increase in the concentration of poly(L-lysine) in a vortexing
solution of DNA results in the formation of
DNA/ligand-poly(L-lysine) particles of defined size and shape. I
hypothesize that binding of poly(L-lysine) to DNA initiates
condensation by forming a nucleus of condensation along the DNA
length. Further addition of poly(L-lysine) results in the formation
of aggregated DNA/ligand-poly(L-lysine) complexes. The second step
in the formation of stable condensed DNA particles consists in
equilibrating the ionic strength of the solvent to facilitate the
solubilization of the condensed DNA particles. Several biochemical
parameters have been studied and correlated with the functional
activity of DNA/ligand-poly(L-lysine) particles in transferring
genes to the liver of adult animals by receptor-
mediated
endocytosis. Based on these findings, a model for the interaction
between the DNA and the ligand/poly(L-lysine) is proposed and the
implications for the effective
transfer of genes into animals in
vivo discussed. The model proposed indicates a role for the
polycation in both the formation of suitable particles for
gene
transfer, and the efficient
transfer of the DNA to the nucleus of
cells

▼ Gene therapy is an attractive treatment for many genetic diseases because rather than
treat the symptoms of the disease, it has the potential to correct the underlying
defect. Cystic fibrosis and hemophilia A are two monogenic disorders that are
particularly well-suited to treatment with
gene therapy as a relatively small increase
in the function is needed to see improvement.
Gene therapy has provided some correction
in both diseases using a variety of vector systems but sustained expression and long
term correction have yet to be demonstrated in the clinic. It is unclear in which cell
type(s) correction of the underlying defect in cystic fibrosis will be most effective.
Studies indicate that the majority of CFTR expression is in the submucosal glands and
ciliated epithelia – a terminally differentiated cell type (Engelhardt, J.F. et al,
2004, Journal of Clinical Investigation). Therapeutic
gene transfer would thus be most
effective if achieved in a progenitor cell type. Additionally, the native regulation of
CFTR has not been definitively elucidated. To this end, one goal of our studies is to
develop a lentiviral vector system with heterologous promoters of varying strengths and
cell specificity to aid in our selection of optimal reagents for appropriate CFTR
expression. We show that use of novel internal promoters from the human PLUNC and WDR65
genes direct persistent expression in the airway. Additionally, disruption of the nasal
epithelium with the detergent polidocanol eliminated reporter expression in mouse
airway. Two weeks post-treatment, expression returned indicating targeting of a
progenitor cell population with our novel vectors.
Integrating vector systems can treat chronic diseases such as cystic fibrosis because
expression can persist long term from these vectors if cells with progenitor capacity
are targeted (Sinn, P.L. et al, 2005, Journal of Virology). However, the potential for
genotoxicity from vector-related dysregulation is a concern. Thus, a second aim of these
studies was to develop a lentiviral vector that can target a specific locus in the
genome. We developed a FIV vector in which the integrase was modified with a
protein-binding domain that when co-delivered with a fusion consisting of the cognate
protein and a DNA binding domain would tether the vector to the appropriate locus.
Unfortunately, integrase modification rendered the vector catalytically inactive. Lastly, we hoped to develop a non-viral
transposon vector system (piggyBac) for
gene
transfer applications to the liver for treatment of hemophilia A. The recent
demonstration that piggyBac transposase is highly active in mammalian cells warrants
further development…

▼ Skin cancer is one of the most common forms of adult solid tumour. The incidence is increasing rapidly making skin cancer a major health problem in several countries. Cutaneous Malignant Melanoma (CMM) is the least common but the most life threatening type of skin cancers and is responsible for 90% of all skin malignancy associated deaths. The precise cellular and molecular etiology of malignant melanoma is quite complex and the molecular events directly related to melanoma progression are yet to be elucidated. However, recent advances in molecular biology have resulted in a clearer understanding of the cellular and molecular events of skin cancer development. The best-characterized locus associated with CMM development is the CDKN2A that maps to chromosome 9p21 and encodes for the cell cycle regulator p16 tumour suppressor gene (TSG), and is frequently inactivated in melanoma tumours. In addition to p16, other loci located in 9p21 appear to be important in CMM development and functional evidence for the presence of TSG(s) has been provided (Parris et al., 1999). The aim of our study is to contribute to the understanding of CMM development by isolating and characterising novel TSG(s) at this location. In order to pursue identifying potential TSG(s), we have developed several monochromosome hybrids using microcell mediated chromosome transfer, and evaluated the tumourigenicity of the constructed hybrids by anchorage independent growth in soft agar. For the molecular biology aspects, expression analysis of the genes in the 9p21 region was carried out by reverse transcription PCR. Potential candidate tumour suppressor genes were then carefully evaluated by generating expression profiles via conducting real time PCR. Experimental evidence is provided which supports the candidacy of interferon alpha 1 (IFNA1) as a tumour suppressor gene for melanoma development.

▼ Genome sequencing of Plasmodium falciparum is
almost complete but the functional analysis of the Plasmodium
falciparum genome is restricted because of our limited ability to
genetically manipulate this malaria parasite.
Gene regulation is
one of the most intriguing and enigmatic aspects of malaria
parasite biology. The ability of the parasite to control
differential
gene expression is poorly understood and so far only a
few Plasmodium promoters have been identified that share no
significant homology with either themselves or with other
eukaryotic promoters.
maebl is a paralogue of the ebl
gene family in
P. falciparum and is expressed at a different time point in the
blood stages of the parasite as compared to the other well
characterized members of the family, baebl and eba-175. Transcript
analysis by northern blot hybridizations and Random amplification
of cDNA ends (RACE) idenitifed a much longer 5’ untranslated region
for maebl when compared to baebl and eba-175, suggesting the
possibility of post-transcriptional regulation for maebl. A single
transcription start site was mapped for eba-175 and multiple
transcription start sites were identified for baebl and maebl. In
order to test the promoter activity of the 5’ regions of baebl,
eba- 175 and maebl, a modified Chloramphenicol acetyl transferase
(CAT) reporter assay was developed for P. facliparum that is more
accurate and user-friendly compared to the conventional CAT assays.
The 5’ regions of all three genes expressed CAT from episomes in P.
falciparum blood stages confirming the presence of promoter
elements in 5’ regions. So far, only a few promoters are used for
transgene expression in P. falciparum and our results show that the
5’ regions of these three ebl genes could be used for the same.
MAEBL is expressed in the mid-trophozoite
stages of blood-stage development and is located on the surface of
merozoites just before the invasion of new host erythrocytes. To
understand the role of MAEBL in erythrocyte invasion, maebl was
disrupted in P. falciparum NF54 parasites by single homologous
recombination. There was no apparent phenotypic effect of maebl
disruption in these parasites. Erythrocyte invasion assays
performed on different enzymatically-treated erythrocytes showed
that maebl is not essential for blood-stage development and the
disruptant clones had a similar invasion phenotype to that of
wild-type parasites. It is possible that the function of MAEBL is
complemented by another parasite protein hence masking the effect
of maebl disruption. In the rodent malaria parasite, P. berghei,
MAEBL has been shown to be essential for mosquito salivary gland
invasion by malarial sporozoites. In future, we would like to
confirm a similar role for MAEBL in P. falciparum using the maebl
disruptant clones and also investigate the possible role for MAEBL
in the sporozoite invasion of human liver cells.
Application of new technologies has produced a
wealth of information in recent years about the genomes, proteomes,
and other aspects…

▼ Among contemporary gene transfer vehicles, non-pathogenic recombinant adeno-associated viral vectors (rAAV) show exceptional promise for liver-targeted therapeutic approaches. The broad focus of studies described in this thesis was the development of rAAV-mediated gene therapy to treat Progressive Familial Intrahepatic Cholestasis type 3. This autosomal recessive condition, caused by mutations of ABCB4, results in deficient hepatocanalicular phosphatidylcholine translocation and leads to progressive cholestatic liver disease with approximately 50% of patients requiring liver transplantation before reaching adulthood. Using an Abcb4-knockout mouse model, in vivo liver transduction with rAAV2/8 vectors encoding hABCB4 led to increased biliary phosphatidylcholine in disease-free heterozygous, but not in homozygous adults with established liver disease, despite varying vector genome size and routes of administration. Maximal transduction was achieved prior to onset of liver disease, optimally in neonates. However, loss of transgene expression occurs following neonatal vector delivery, due to rAAV episomal degradation during rapid liver growth. A novel, hybrid rAAV-piggyBac transposon vector strategy was devised to sustain hABCB4 expression in neonatally-treated homozygotes. Successful correction of liver disease was demonstrated in Abcb4-/- mice up to 9 months post-inoculation, with preliminary results indicating reduction in disease-related hepatocarcinogenic risk. These results demonstrate that rAAV-mediated gene therapy has the potential to offer patients with this heritable cholestatic liver disease an effective alternative treatment to liver transplantation, but also illustrate the importance of addressing challenges, such as the impact of liver pathology on vector performance, which is vital before this potential can be realised for this and related conditions.

The impact of Terminal Inverted Repeat (TIR) transposable elements on plant genomes.

▼ As major components in eukaryotic genomes, Transposable Elements (TEs) have been studied for decades. In the 1950s to 1990s, the predominant opinions considered TEs as “junk DNA” and “selfish elements”. However, subsequent studies showed that TEs are important players in genome dynamics. TEs are presented in many shapes and characteristics in genomes. Generally, two classes of TEs are distinguished by their transposition features: Class I TEs rely on RNA for their transposition, and Class II TEs are independent of RNA intermediates. In this thesis, I focus on the major type of Class II TEs which is called Terminal Inverted Repeat (TIR) elements. While most of the TIR TEs are heavily methylated and are considered inactive, recent studies have shown that in many plant genomes some TIR TE families are still able to transpose. Besides that, in certain situations, different TEs are capable to work together to generate larger rearrangements in genomes. In this thesis, I present our findings of novel TIR activities and the tools we developed to facilitate TE studies. This thesis contains 6 chapters and these results will contribute to our knowledge of TIR TEs in plant genomes.
In the first chapter, I summarize the evolutionary impacts of TIR elements when they mobilize through alternative transpositions. Unlike standard transposition, alternative transposition involves two distinct TEs and generates more complicated genome rearrangements such as deletion, inversion, duplication, and translocation. The first chapter serves as an introduction to alternative transposition. I describe various types of alternative transposition induced by TIR transposable elements and their outcomes.
In the second chapter, I present our results of Composite Insertions (CIs), a novel structure generated by Ac/Ds induced alternative transposition. We used maize pericarp color 1 (p1) and pericarp color 2 (p2) genes as a genetic system to identify CIs. We analyzed their structures and proved our hypothesis that these CIs can regulate gene expression by duplicating and shuffling enhancer elements. Previous studies have shown that transposable elements perform enhancer-like activities. The mechanism behind this function is typically related to the evolutionary forces, which drive TEs evolving into regulatory elements. Also, most of these studies were focused on Class I TEs in animal and human systems. This chapter demonstrates an alternative way of how Class II TEs contribute to gene regulation in maize.
To analyze the larger impact of TIR TEs, we developed a bioinformatics pipeline called TIR-Learner. It is a new ensemble method for TIR Transposable Element annotation. In chapter 3, I introduce the algorithms and methods used in TIR-Learner, and the analysis of Maize TIR elements we performed by using TIR-Learner. TIR-Learner combines the advantages of current homology-based annotation methods with the powerful de-novo machine-learning approaches, resulting in better efficiency and accuracy of TIR element annotation. By using this pipeline, we…

Transcriptional regulation of mobilization and transfer of the Bacteroides conjugative transposon CTnDOT.

▼ Bacteroides spp. are a primary inhabitant of the human colon, and play an important role in the health of the human host as Bacteroides are important for nutrient acquisition, the breakdown of starches that would otherwise go undigested, and the management of relevant pathogens such as C. difficile. Although generally considered a commensal, Bacteroides can become an opportunistic pathogen if it should escape the colon. Bacteroides is the most commonly isolated causative agent of anaerobic infections, and these infections are rather difficult to treat due to the prevalence of antibiotic resistance within this genus. The prevalence of resistance determinants in Bacteroides is often due to mobile genetic elements. One such element is a conjugative
transposon (sometimes referred to as an integrative conjugative element, or ICE) called CTnDOT, which is a 65 kb ICE that encodes resistance to the antibiotics erythromycin and tetracycline. A notable feature of CTnDOT is that excision from the donor chromosome and conjugative
transfer are coordinately regulated upon exposure of donor cells to tetracycline (Tc). While no
transfer is detected in the absence of Tc, upon Tc induction a regulatory cascade ultimately stimulates synthesis of the excision proteins, which are required for excision of CTnDOT from the chromosome. These proteins also have a regulatory role, in that they are required for the transcriptional activation of the 13 kb tra operon that encodes the mating apparatus. The work presented in this dissertation has characterized a negative regulator, RteR, that appears to prevent conjugative
transfer of CTnDOT in the absence of Tc by possibly initiating the formation of an intrinsic terminator within traB, thus truncating the transcript so there is no substrate for translation, and hence no proteins are formed to assemble the mating apparatus. For the first time, we also describe the regulation of the CTnDOT mobilization region. These three genes that encode the relaxases and coupling protein required for mobilization are organized in an approximately 4 kb operon that is regulated upon Tc induction. The excision proteins Xis2d and Exc are required for enhancement of mob transcription upon exposure to Tc. This differs from the neighboring divergently transcribed tra operon, which does not require Exc, but also requires Xis2d and in addition Xis2c. A negative regulator is preventing mob transcription in the absence of Tc, and we currently predict that a
gene encoded downstream of intDOT, orf2, is the mob transcriptional repressor. Taken together, the work described in this dissertation has further shed light on the intricate regulation governing the conjugative
transfer of CTnDOT.

▼ Muitas das técnicas utilizadas para gerar animais transgênicos são caras e laboriosas. Neste contexto, a transferência gênica mediada por espermatozóides (TGME) pode ser uma alternativa para a produção em larga escala de animais transgênicos. Estudos de SMGT têm seu foco no número de cópias de DNA incorporada pelo espermatozóide. Por isso, há pouca informação disponível sobre como as moléculas de DNA se comportam durante o processo de fecundação e quais os efeitos dos protocolos de TGME sobre a célula espermática. Neste sentido, com o objetivo de avaliar a existência de sitio de integração preferencial das moléculas exógenas de DNA no genoma hospedeiro, utilizamos a hibridização in situ para acompanhar a veiculação do transgene durante o processo de fecundação. Foram avaliadas as membranas acrossomais, plasmática e potencial de membrana mitocondrial de espermatozóides submetidos a TGME. Para isso, o sêmen de três diferentes touros foram submetidos ao gradiente de Percoll 45-90%. As células viáveis foram incubadas com o vetor recombinante pCX-EGFP (0, 250, 500 ou 1000ng/106 células) seguidas ou não de eletroporação (300v, 35µF e 0,25ms). Os espermatozóides tratados foram utilizados para a produção in vitro de embriões. Os embriões foram cultivados por sete dias até o estágio de blastocisto. Espermatozóides e embriões produzidos in vitro foram submetidos ao ensaio de hibridização in situ, com metodologia descrita Whyte et al. (2000). O potencial de membrana mitocondrial (PMM), integridade de membrana acrossomal (MA) e plasmática (MP) foram avaliados por citometria de fluxo (Guava Technologies, Hayward, CA, USA) utilizando as sondas fluorescentes JC1, FITC-PSA e PI (Molecular Probes), respectivamente. Os dados foram analisados pelo teste paramétrico ANOVA (teste LSD) usando o programa estatístico SAS for Windows, com nível de significância de 5%. A hibridização in situ não foi possível em espermatozóides bovinos, pois não houve hibridação da sonda controle. Blastocistos oriundos de espermatozóides incubados com DNA exógeno apresentaram integração de forma difusa, embriões oriundos de espermatozóides eletroporados apresentaram integração pontual. As diferentes concentrações de DNA não exerceram efeitos deletérios nas MP ou PMM, a adição de 500ng de DNA causou aumento de lesão na MA (p<0,05). A eletroporação não afeta a MP e MA, mais apresenta grande efeito no PMM causando redução da função mitocondrial. Este estudo conclui que maiores esforços são necessários para elucidar o comportamento das moléculas exógenas de DNA durante o processo de fecundação e quais são os efeitos da TGME sobre a célula espermática.
Most techniques used to produce transgenic animals are laborious and expensive. In this manner, sperm mediated gene transfer (SMGT) may be a viable alternative for long-scale production of transgenic animals. Many SMGT studies have focused the DNA internalization and number of DNA copies incorporated by spermatozoa. However, limited data is available about how foreign DNA…

▼ With sequencing technology becoming more advanced and widely available, so has the ability to describe the forces and processes shaping genome architecture. Spontaneous mutations such as nucleotide substitutions, indels, duplications,
large-scale insertions and deletions, inversions, and translocations provide the input that is then acted on by adaptive (natural selection) and non-adaptive (recombination, random genetic drift) processes to create the genetic variation within and among
species. Through this dissertation, I use a combination of experimental evolution and comparative genomics to examine these four forces and how they act to create and maintain the genome. First, through two mutation accumulation experiments, I
investigate the rates, biases and spectra of mutation and recombination in the absence of selection. Lastly, I discuss the effect of genome wide selection on premature termination codons in introns across seven model organisms.

▼ Plants as sessile organisms are susceptible to many environmental stresses such as drought, and salinity. They have therefore evolved mechanisms to acclimate and tolerate environmental stresses. Knowledge of the molecular aspects of abiotic stress gleaned from extensive studies in Arabidopsis has provided much information on the complex processes underlying plant response to abiotic stresses. Nevertheless, there is a need for integration of the knowledge gained and a systematic molecular genetic dissection of the complex responses to abiotic stress. In this study in Arabidopsis, comparative expression profiling analysis of progressive (pDr) and moderate (mDr) drought treatments revealed common drought responses, as well as treatment specific signatures responses to drought stress. Under prolonged moderate drought plants develop different mechanisms for acclimation: induction of cell wall loosening at early stage, and a change in hormonal balance (ABA: JA) at late stage of moderate drought. Taking a reverse genetics approach, a MYB transcription factor (MYB109) has been identified as a regulator of growth under drought and salt stress. Global expression profiling showed possible mechanisms of how MYB109 modulates growth under drought conditions: as a regulator of RNA processing and splicing and as a negative regulator of jasmonic acid biosynthesis and signaling. A forward genetics screen for drought and salt tolerance of
transposon activation tag (ATag) lines led to the discovery of novel genes, which shed light on unexplored areas of abiotic stress biology. Utilizing this strategy, a potential role for cell wall modification and MATE transporters in response to drought and salt stress has been discovered, which needs further analysis to integrate this information on the role of these biological processes in plant stress biology.

▼ Microorganisms are omnipresent and exist as communities within and around the human body. These communities, regardless of location, may cause disease: dysbioses within the gut microbiota are associated with obesity and inflammatory bowel disease, while differences in immune development and environmental exposures are linked to atopy and diabetes. It is thus crucial to characterize microbial communities and their interactions to better understand how they are formed, maintained, and manipulated. To better understand the ecology of communities on and around the human body, my work has explored lateral gene transfer (LGT) within human-associated microbial communities and the transfer of microbes between the human body and environmental surfaces.
I developed the first method for detection of de novo LGT events from metagenomes termed WAAFLE, a Workflow to Annotate Assemblies and Find LGT Events. I applied WAAFLE to the Human Microbiome Project: LGT frequencies were highest in the gut and oral sites, and lowest in the vaginal and skin microbiomes. High frequency pairs corresponded with increased taxon abundances and close phylogenetic distances. Taxa found in multiple LGT pairs had strong partner preferences, and several had biases in transfer directionality. Enriched functions in LGT contigs included transposases, phage, and TonB membrane receptors. Taxa in high frequency LGT pairs may preferentially use LGT as a tool to maintain or change their community status.
I examined cross-talk between human-associated and built-environment microbial communities in heavily trafficked environments, specifically the Boston subway. These areas may facilitate microbial transmission and are ripe for public health interventions such as sanitation or architecture. We used 16S rRNA gene and metagenomics shotgun sequencing to profile microbes on multiple surface types in trains along the red, green, and orange lines, as well as ticketing machines at four train stations. Community structure was dictated by surface type, rather than train line. Common taxa included human skin and oral commensals such as Propionibacterium, Corynebacterium, Staphylococcus, and Streptococcus. Enriched functions were often from Propionibacterium acnes pathways, and few antibiotic resistance genes were observed. Overall, microbial communities on the Boston subway are likely derived from the rider population and influenced by rider interactions and environmental biochemistry.

▼ The very potent antibacterial activity of cecropin B makes it a likely candidate to prevent and/or treat Mannheimia haemolytica 1:A infection in the upper respiratory tract (URT) of cattle. The purpose of this study was to ascertain if the URT could be transfected with a gene coding for the antimicrobial peptide cecropin B. By transfecting cattle with a gene coding for cecropin B, this study attempted to inhibit colonization of a virulent strain of M. haemolytica 1:A in the URT while investigating any possible changes in the indigenous and transient nasal flora. In this study the antibacterial efficacy of cecropin B for a virulent strain of M. haemolytica 1:A was determined. In vitro results showed that cecropin B was very effective in inhibiting this virulent strain of M. haemolytica 1:A within 20 minutes of incubation at 37°C. No inhibition of its activity was observed by incubating cecropin B in pooled bovine nasal secretions. The nasal passages of calves were aerosolized with different amounts of plasmid DNA containing a gene coding for cecropin B. Results of this study show that calves transfected with 50 or 100 μg of plasmid DNA per nostril were able to express cecropin B at the mRNA and peptide level. Detection of the cecropin B gene in control calves may indicate the possibility of native bovine cecropin. After challenge with a virulent strain of M. haemolytica 1:A, all calves were stressed by transportation in a crowded trailer 100 miles for 3 hours. Seven out of the 8 control calves yielded detectible levels of M. haemolytica 1:A in nasal aspirates throughout the weeks following challenge. All 4 calves given 25 μg of plasmid DNA per nostril and two of the 4 calves given 50 μg of plasmid DNA per nostril yielded detectible levels of M. haemolytica 1:A in nasal aspirates following challenge. However, M. haemolytica 1:A was not detected in any calf given 100 μg of plasmid DNA per nostril. There appeared to be no change in the normal bacterial nasal flora.

▼ Horizontal
gene transfer (HGT) is thought to be an important driving force for microbial evolution and adaptation, including the development of antibiotics resistance and niche adaptation. Metagenomics provides an opportunity to study HGT on the level of microbial communities, however, analysis method for this are currently lacking. Here, I developed three bioinformatic pipelines to aid the detection of HGT in metagenomic datasets.Firstly, Binning_refiner was developed to improve the quality of genome bins derived from metagenomic datasets through the combination of different binning programs. The results demonstrated that Binning_refiner can significantly reduce the contamination level of genome bins and increase the total size of contamination-free genome bins. Secondly, HgtSIM was developed to simulate HGT events among microbial community members with user-defined mutation levels. It was developed for testing and benchmarking pipelines for recovering HGTs from complex microbial communities. Thirdly, MetaCHIP was developed to identify HGTs at the community-level through the combination of best-match and phylogenetic approaches. Assessment of its performance on both simulated and real datasets showed that it can effectively predict HGTs with various degrees of genetic divergence from microbial communities. The results also showed that the detection of very recent
gene transfers (i.e. those with genetic divergence < 5%) from metagenomic datasets is affected by the read assemble step, as the genomic background of recently transferred genes cannot be recovered with currently available assemblers. And finally, the potential application of long-read sequencing (PacBio) for metagenomics was also explored. A simulated metagenome of pooled genomic DNA from ten marine bacteria with various degrees of genome similarity was sequenced on the PacBio sequencing platform and ten complete high-quality genomes were assembled. The findings and developments made here, including a reference-based read phasing approach for the assembly of highly similar genomes, can be used in the future to design strategies to analyse long-read sequencing data for mixed bacterial communities.

▼ Colletotrichum truncatum (Schwein.), Andrus & W.D. Moore (1935) is the main pathogen of chili (Capsicum spp.) causing anthracnose disease in the tropical and sub-tropical regions of Asia and Australia. Anthracnose disease can cause severe economic loss through reduced yield and marketability of infected fruit. The use of conventional methods to control for anthracnose disease of chili in the field is not effective in reducing crop loss. In severe epidemics, losses of up to 80% of the total yield can be quite significant to the industry. Furthermore, no resistant commercial cultivars of chili (Capsicum annuum) exist, although resistance has been detected in genotypes of the related species, C. chinense and C. baccatum. Knowledge of the molecular genetic mechanism(s) of pathogen infection and the processes that trigger the host defence strategies would be informative towards developing/breeding for resistant chili genotypes.
Pathogenesis of C. truncatum on chili is an intricate and complex process which is an outcome of the expression of various pathogenicity-related (PR) genes that evade or overcome host defences. In this study, PR genes of two C. truncatum pathotypes F8-3B and BRIP26974, possibly involved during the infection of Capsicum were isolated using a PCR-targeted approach. Molecular identification revealed that almost all of the targeted PR genes were present in the genome of C. truncatum. EndoPG1 was found to be highly homologous to the PG1 in C. lindemuthianum and Cut1 to the cutinase in C. capsici and C. gloeosporioides. The conventional and modern PCR techniques such as RT-PCR and qRT-PCR were used to qualitatively and quantitatively screen and predict genes that were differentially expressed at the early stage of C. truncatum infection. Expression profiles of Cap20, EndoPG1, G-Protα, CLSP1 and Cut1 were differentially regulated during the saprophytic and pathogenic stages. However, significant expression changes were observed in the cell wall and cuticle degrading enzymes, EndoPG1 and Cut1. Cutinase is an extracellular enzyme involved in the penetration of the host cuticular barrier into the host plant during the initial stages of the fungal infection. Overall, the transcript expression of EndoPG1 reached a maximum at 6 hours after inoculation (HAI). In contrast, Cut1 transcript showed greatest upregulation at 24 HAI. Consequently, the full length CtCut1 gene was isolated from C. truncatum and its molecular characteristics were analysed.
To facilitate the study of gene function in fungal-plant interactions between C. truncatum and chili, a robust Agrobacterium tumefaciens-mediated transformation (ATMT) system was developed for C. truncatum. A. tumefaciens carrying a hygromycin phosphotransferase gene (hph) and a green fluorescent protein (gfp) gene was used to transform the conidiospores of C. truncatum pathotypes F8-3B and BRIP26974. Optimum transformation efficiency was obtained when equal amounts of A.…

▼ Os elementos de transposição são seqüências discretas que são capazes de mover- se de um lócus para outro, constituindo uma parte significante do genoma de eucariotos. São agrupados em duas classes principais, os elementos da Classe I, que se transpõem via um intermediário de RNA (retrotransposon), e os elementos da Classe II, que se transpõem via mecanismo de DNA do tipo corta e cola (
transposon). A análise das seqüências de um banco de cDNA construído com RNA mensageiro da glândula salivar de Rhynchosciara americana mostrou a presença de representantes das duas classes de elementos. Nesse trabalho caracteriza-se quarto elementos de transposição tipo mariner, onde as seqüências consenso de nucleotídeos foram derivadas de múltiplas cópias defectivas contendo deleções, mudança no quadro de leitura e códons de terminação. Ramar1, um elemento full-length e Ramar2 um elemento defectivo que contém uma deleção na região interna da ORF da transposase, mas mantém e as extremidades intactas. Ramar3 e Ramar4 são elementos defectivos que apresentam muitas deleções no interior da ORF. As seqüências preditas das transposases demostraram que Ramar1 e Ramar2 estão filogeneticamente muito próximos dos elementos mariner da subfamília mauritiana. Enquanto, Ramar3 e Ramar4 pertencem às subfamílias mellifera e irritans, respectivamente. Hibridização in situ mostrou que Ramar1 localiza-se em muitas regiões do cromossomo, principalmente na heterocromatina pericentromérica, enquanto Ramar2 aparece em uma única banda no cromossomo A. Resultado ainda mais curioso foi a caracterização molecular de um elemento de retrotransposição, denominado RaTART, que provavelmente é o responsável pela reconstituição telomérica em R.americana, assim como os elementos TART, HeT-A e TAHRE de Drosophila. Experimentos de Southern Blots do retroelemento RaTART indicam que este está representado por seqüências repetidas no genoma de R.americana, enquanto que Northern Blots mostraram uma expressão em diferentes estágios do desenvolvimento e o transcrito de alto peso molecular detectado representa o retrotransposon non-LTR inteiro. Enquanto a localização cromossômica de RaTART por hibridização in situ mostrou uma marcação predominante nas extremidades dos cromossomos, indicando possivelmente o primeiro elemento de transposição descrito em R.americana com função definida na estrutura do cromossomo. O último retrotransposon, identificado nesse projeto, presente no genoma de R.americana, denominado R2Ra, foi isolado a partir de uma varredura em um banco genômico construído no bacteriófago lambda dash usando como sonda o recombinante pRa1.4 que contém a unidade de repetição do rDNA. A análise da seqüência mostrou a presença de regiões conservadas, como o domínio de transcriptase reversa e o motivo zinc finger na região amino-terminal. O sítio de inserção no
gene 28S do rDNA é altamente conservado em R.americana e a análise filogenética mostrou que este elemento pertence ao grupo R2. A localização cromossômica confirma que o…

▼ Antimicrobials have been widely using as a major resource to treat bacterial infections for almost a century. However, it is not unusual to see antimicrobial resistance emerges in a bacterial species due to natural selection under the usage of antimicrobials. Moreover, numerous studies show that bacteria can accumulate genes encoding resistance to different classes of antimicrobials and share them with other bacteria regardless of ancestry via a biological process called horizontal gene transfer, causing emergence and fast transmission of multidrug resistance. As such, antimicrobial resistance becomes an urgent and global threat to public health, pushing us backwards to the pre-antimicrobial era.
In this thesis, I focus on horizontal co-transfer of resistance genes between bacteria of the same species, which is usually caused by co-localisation of resistance genes in mobile genetic elements, also known as physical linkage between these genes. This kind of linkage plays a pivotal role in the evolution of multidrug resistance, because the mobile elements can translocate, recombine and aggregate, rapidly rendering their host bacteria resistant to a wide spectrum of antimicrobials. By far there is nonetheless not an approach identifying horizontally co-transferred genes in a single bacterial species. Yet most authors of literature reported a few co-mobilised resistance genes each time following biological experiments, and some researchers only applied simple association analysis to representative bacterial isolates of distinct species so as to minimise the possibility that a specific combination of genes is inherited from their most-recent common ancestor. In contrast, intra-species association analysis is severely confounded by strong sample relatedness because of bacterial clonal reproduction. This obstacle leaves a gap between the known high frequency of intra-species horizontal gene transfer and our understandings of this process.
This thesis presents a scalable computational approach that uses whole-genome sequencing data to identify co-transferred antimicrobial resistance genes in bacteria collected in a few decades from the same species. Moreover, it demonstrates applications of the approach to three clinically important pathogens and reports key players, patterns and dynamics underlying the horizontal co-transfer of resistance genes within each species.
In the first chapter, I provide a background to antimicrobial resistance, horizontal gene transfer, whole-genome sequencing and contemporary bioinformatic techniques. I also summarise outcomes of horizontal gene co-transfer for characteristics that we can utilise for inference of physical linkage. Finally, I compare several statistical approaches determining pairwise association between presence-absence status of genes or alleles in bacteria to justify the necessity of controlling for sample relatedness in association analysis.
For the second chapter, I derived a methodology inferring co-transferred genes by integrating gene detection, de novo genome…

Επιπλέον, έχει αντιφλεγμονώδη και αντιοξειδωτική δράση. Η κύρια πρωτεΐνη της HDL είναι η απολιποπρωτεΐνη Α-Ι (apoA-I). Ωστόσο, πρόσφατα αποδείχθηκε ότι σε πειραματόζωα με έλλειψη στην apoA-I και κατά συνέπεια στην κλασσική HDL, η απολιποπρωτεΐνη Ε (apoE) αλληλεπιδρά με τον μεταφορέα λιπιδίων ABCA1 προάγοντας την de novo σύνθεση HDL σωματιδίων. Στην παρούσα μελέτη, στόχος ήταν η εύρεση της περιοχής της apoE που είναι υπεύθυνη για την λειτουργική αλληλεπίδραση με τον ABCA1 για το σχηματισμό HDL. Για το σκοπό αυτό, ανασυνδυασμένοι αδενοϊοί που εξέφραζαν καρβοξυ-τελικές συντετμημένες μορφές της apoE4 (AdGFP-E4[1-259], AdGFP-E4[1-229], AdGFP-E4[1-202], AdGFP-E4[1-185]), χορηγήθηκαν σε ποντίκια με έλλειψη στην ApoA-I σε δόση 8x108 pfu και πέντε μέρες μετά τη μόλυνση δείγματα πλάσματος αναλύθηκαν για το σχηματισμό HDL. Κλασματοποίηση των λιποπρωτεϊνών του πλάσματος με υπερφυγοκέντρηση σε διαβάθμιση πυκνότητας καθώς και FPLC χρωματογραφία αποκάλυψε ότι όλες οι συντετμημένες μορφές της apoE4 προάγουν το σχηματισμό HDL. Ανάλυση ηλεκτρονικής μικροσκοπίας με αρνητική χρώση των HDL κλασμάτων, επιβεβαίωσε ότι όλες οι συντετμημένες μορφές της apoE4 είναι ικανές να προάγουν το σχηματισμό σωματιδίων με διάμετρο στην περιοχή της HDL. Τα δεδομένα αυτά οδηγούν στο συμπέρασμα ότι η αμινοτελική περιοχή της apoE που εκτείνεται από τα αμινοξέα 1 έως 185 αρκεί για το σχηματισμό HDL σωματιδίων in vivo. Αυτά τα ευρήματα, ανοίγουν το δρόμο στην έρευνα για το σχεδιασμό βιολογικών φαρμάκων με βάση την apoE για τη θεραπεία της δυσλιπιδαιμίας, της αθηροσκλήρωσης και της στεφανιαίας νόσου.
HDL is a mixture of high density lipoprotein particles that depending on the lipid composition may be discoidal or spherical. The main atheroprotective property of HDL is reverse cholesterol transport, a process that unloads excess cholesterol from peripheral tissues and transports it to the liver for catabolism. HDL has also anti-inflammatory and antioxidant properties. The main protein of HDL is apolipoprotein A-I (apoA-I). However, recently it was shown that in the absence of apoA-I and consequently classical HDL, apolipoprotein E (apoE) interacts functionally with the lipid transporter ABCA1, promoting the de novo synthesis of HDL-like particles. The present study focused on the identification of the domain of apoE that is responsible for the functional interaction with ABCA1 and the formation of apoE-containing HDL. Recombinant attenuated adenoviruses expressing carboxy-terminal truncated forms of apoE4 (apoE4[1-259], apoE4[1-229], apoE4[1-202], and apoE4[1-185]) were administered to apoA-I-deficient mice at a low dose of 8x108 pfu and five days post-infection plasma samples were isolated and analyzed …

▼ The specific aims of this dissertation were twofold: (1) to establish an experimental model system in which cardiac contractile protein expression could be rapidly and efficiently altered to study structural and functional relationships, and (2) to assess the structural and functional consequences of ectopic expression of two mutant troponin T proteins which are linked to the disease hypertrophic cardiomyopathy using this experimental model system. In order to accomplish the first goal, two cardiac myocyte culture systems were studied. The first was cardiac myocytes derived from mouse embryonic stem cells differentiating in vitro. Infection of these cultures with recombinant adenovirus vectors led to expression of the transferred
gene in ~27% of the cardiac myocytes for up to 21 days without altering cardiac myocyte differentiation or contractile function. The second system studied was adult cardiac myocytes in primary culture. Infection of these cultures with adenovirus vectors led to stable expression of the transferred
gene in >90% of the myocytes for the 7 day culture period, without affecting myocyte structure or the ability of the myocytes to respond to calcium activation. Due to the greater efficiency of
gene transfer and stable adult cardiac myocyte phenotype structurally and functionally, this second system was used to study the effects of expressing two mutant troponin T proteins on cardiac myocyte structure and function. Expression of each of the mutant troponin T proteins in adult cardiac myocytes led to a significant decrease in the calcium sensitivity of contraction, but did not appear to alter myocyte structure. In conclusion, an experimental model system, adult cardiac myocytes in primary culture, has been defined which can be rapidly and efficiently modified using adenovirus
mediated gene transfer.
Gene transfer of each of two mutant troponin T proteins resulted in a significantly decreased cardiac contractile response to calcium activation, supporting the role of these two mutant proteins in causing hypertrophic cardiomyopathy.

▼ We demonstrate that hydrogen production can be increased by random mutagenesis
using N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and that hydrogen production can be
further increased in the chemically-mutagenized strain by targeted
gene deletion and
overexpression of genes related to formate metabolism. Chemical mutagenesis of Escherichia
coli BW25113 hyaB hybC hycE::kan/pBS(Kan)-HycE to form strain 3/86 resulted in 109 +/- 0.5-
fold more hydrogen; 3/86 lacks functional hydrogen uptake hydrogenases 1 and 2, has hydrogenproducing
hydrogenase 3 inactivated from the chromosome, and has constitutively active
hydrogenase 3 based on expression of the large subunit of hydrogenase 3 from a high copy
number plasmid. Deleting fdoG, which encodes formate dehydrogenase O, (that diverts formate
from hydrogen), from chemical mutagen 3/86 increased hydrogen production 188 +/- 0.50-fold
(relative to the unmutagenized strain), and deletion of hycA, which encodes the repressor of
formate hydrogen lyase (FHL), increased hydrogen production 232 +/- 0.50-fold. Deleting both
fdoG and hycA increased hydrogen production 257 +/- 0.50-fold, and overexpressing fhlA along
with the fdoG hycA mutations increased hydrogen 308 +/- 0.52-fold. Whole-transcriptome
analysis of chemical mutagen 3/86 revealed 89 genes were induced and 31 genes were repressed.
In an effort to identify chromosomal mutations in chemical mutagen 3/86, we performed
comparative genome sequencing and identified two chromosomal loci with mutations in coding regions of ftnA and yebJ; however, neither
gene was related to the increased hydrogen
production as determined by the close vial (short) hydrogen assay.
In addition,
transposon mutagenesis, which is one of the most efficient strategies for
creating random mutations in the genomic DNA, was performed in two different strains: E. coli
BW25113 hyaB hybC hycA fdoG::kan/pCA24N-FhlA and E. coli MG1655 to identify beneficial
mutations for hydrogen production. As a result of screening 461 E. coli BW25113 hyaB hybC
hycA fdoG::kan/pCA24N-FhlA transformants and 1000 E. coli MG1655 transformants, three
interesting mutations have been discovered in E. coli BW25113 hyaB hybC hycA
fdoG::kan/pCA24N-FhlA transformants (gpsA, dipZ, glgP) and 1 beneficial mutation in E. coli
MG1655 transformants (malT). When any of these genes gpsA, dipZ, or glgP is disrupted by Tn5
insertion, hydrogen production decreases 17, 3 and 8-fold, respectively. Additionally, when malT
gene is disrupted by Tn5 insertion, hydrogen increases 3.4-fold.

▼ Miyoshi Myopathie (MM), Gliedergürteldystrophie Typ 2B (engl. limb girdle
muscular dystrophy 2B, LGMD2B) und die DACM (distal anterior compartment
myopathy) sind seltene, autosomal rezessiv vererbte Krankheiten, die durch
Mutationen im Dysferlin-Gen verursacht werden. Diese muskulären Erkrankungen
werden unter dem Begriff Dysferlinopathie zusammengefasst und betreffen die
proximale und/oder die distale Muskulatur der Extremitäten. Durch eine
zunehmende Schwächung und Atrophie der Muskeln sind Patienten normalerweise
bereits 15 Jahre nach Krankheitsbeginn an den Rollstuhl gebunden.
Behandlungsmöglichkeiten gibt es hier keine. Das Dysferlin-Gen umfasst einen
150 kb-Bereich der genomischen DNA auf Chromosom 2p13 und beinhaltet 55 Exons
mit einer kodierenden Sequenz von 6,2 kb. Dysferlin ist ein 237 kDa Protein
der Ferlinfamilie. Es ist in vielen Geweben vorhanden, vor allem im
Muskelgewebe, wo es in ausgereiften Muskelfasern, aber auch in
Satellitenzellen und Myoblasten exprimiert wird. Dysferlin spielt eine
wichtige Rolle bei der Membranreparatur und der Aufrechterhaltung der T-Tubuli
Struktur in den Muskelfasern. Auβer dem erhöht sich durch ein defektes
Dysferlinprotein die Entzündungsanfälligkeit der Muskelfasern. Die
Regenerationsfähigkeit von Muskeln beruht auf den Muskelstammzellen
(Satellitenzellen) und ihren Abkömmlingen, den Muskelvorläuferzellen
(Myoblasten). Bei Muskelverletzungen, z.B. durch schwere Verwundungen oder
durch Muskelerkrankungen, vermehren sich diese Zellen extensiv um das
geschädigte Gewebe zu reparieren. Satellitenzellen sind durch die Expression
des Transkriptionsfaktors Pax7 gekennzeichnet. Ihre Isolation basiert auf
spezifischen Oberflächenmarkern. Zudem haben sie ein hohes Anwachspotential,
wenn sie in sich regenerierendes Muskelgewebe tranplantiert werden. Deshalb
gilt die autologe oder allogene Transplantation von Satellitenzellen oder
Myoblasten als vielversprechende therapeutische Alternative. Da
Dysferlinopathien durch ein einzelnes Gen verursacht werden, ist zudem die
Gentherapie hier sehr erfolgversprechend. Allerdings werden
Gentransferversuche durch die Gröβe der kodierenden Dysferlinsequenz
erschwert, da die meisten viralen Vektoren, welche für Gentherapiezwecke
benutzt werden, eine zu geringe Ladungskapazität besitzen. Das Sleeping Beauty
Transposon ist ein nicht-virales 2-Komponenten Vektorsystem, welches aus der
DNA Sequenz des Transposons und einem Transposase Protein besteht. Die
Transposase schneidet das
Transposon aus dem Donorplasmid heraus und
integriert es in das Zielgenom. Da das
Transposon so verändert werden kann,
dass es jede Zielsequenz beinhalten kann, ist Sleeping Beauty ein sehr
wichtiges, nicht-virales, genetisches Werkzeug, das einen stabilen Gentransfer
ermöglicht und deshalb häufig in der Gentherapie verwendet wird. Durch das
Sleeping Beauty System kann ein bis zu 8 kb groβes Transgen effizient
integriert werden. Damit ist es auch für die Integration des vollständigen
Dysferlin-Gens sehr gut geeignet. Im Rahmen dieser Arbeit habe ich eine
Methode entwickelt,…

▼ Abstract Although skin disorders affect as much as a third of the population at any given time, available treatments are limited. Because a more comprehensive understanding of skin development mechanisms can spur the identification of new treatment targets and techniques, we developed the Zebrafish Integument Project (ZIP), an expression-driven platform for identifying new skin genes and new, revertible phenotypes in the vertebrate model Danio rerio (zebrafish). In vivo selection for skin-specific expression of gene-break transposon (GBT) mutant lines identified eleven new, revertible GBT alleles of genes involved in skin development. Eight of those genes had been described in an integumentary context to varying degrees: fras1, grip1, hmcn1, msxc, col4a4, ahnak, capn12, and nrg2a. Three others—arhgef25b, fkbp10b, and megf6a—emerged as novel skin genes. Embryos homozygous for a GBT insertion in neuregulin 2a (nrg2a) revealed a novel requirement for a Neuregulin 2a (Nrg2a) – ErbB2/3 – AKT signaling pathway governing ridge cell morphogenesis and apicobasal organization during median fin fold (MFF) morphogenesis. In nrg2a mutant larvae, the basal keratinocytes that comprise the apical MFF (ridge cells) displayed reduced pAKT levels as well as reduced apical domains and exaggerated basolateral domains. Those defects prevented proper ridge cell elongation into a flattened epithelial morphology, resulting in thickened MFF edges. Additionally, morpholino knockdown of epithelial polarity regulator and tumor suppressor lgl2 ameliorated the nrg2a mutant phenotype. Identifying Lgl2 as an antagonist of Nrg2a – ErbB signaling revealed a significantly earlier role for Lgl2 during epidermal morphogenesis than has been described to date. Furthermore, our findings demonstrated that ridge cells’ squamous flattening morphogenesis drives apical MFF development. We therefore propose MFF ridge cells as a new model for investigating the regulation of cell polarity and cellular morphogenesis with regard to their roles as crucial mechanisms for epithelial morphogenesis generally, and for flattening morphogenesis in particular.

▼ The emergence of antimicrobial resistance bacteria has
become a major threat to human society. The rapid spread of
resistant pathogens and the associated loss of efficacy of
available drugs needs to be met with the development of antibiotics
and alternative treatments. Pseudomonas aeruginosa is an
opportunistic human pathogen evolving resistance to many currently
used antibiotics. Chronic lung infections with the bacterium P.
aeruginosa are the leading cause of morbidity and mortality in
cystic fibrosis (CF) patients. Escalating this problem is that
pharmaceutical companies have dropped drug development due to low
profitability, thus making the efforts of drug discovery of prime
importance. To address this global health threat research
institutes have now stepped forward to aid in discovery of novel
compounds. P. aeruginosa dominates the lungs during chronic
infections in CF patients, yet it’s abundance in non-human habitats
such as water and soil is less compared to other diverse groups of
pseudomonads. A trait that could contribute to such decreased
abundance is bacterial competition from other Pseudomonas
populations that dominate water and soil habitats. We hypothesized
that environmental Pseudomonas from diverse soil and water habitats
produce secondary metabolites capable of inhibiting the growth of
CF derived P. aeruginosa. Here, we sought to determine if clinical
isolates of P. aeruginosa are susceptible to competition by
environmental pseudomonads which may provide a source of inhibitory
factors. We have used a population based study in association with
transposon mutagenesis, PCR techniques, whole genome sequencing and
bioinformatic analysis to identify environmental Pseudomonas
biosynthetic
gene clusters (BGCs) and characterize antagonistic
compounds that are effective against CF-derived P. aeruginosa. A
total of five BGCs have been identified in this study from
environmental Pseudomonas strains S4B6, S3F9 (soil-derived) and
LE6C6 (water-derived) encoding diverse compounds such as
bacteriocins, NRPSs, phenazines, and siderophores involved in
antagonistic activity. Extending this analysis, we have also
identified environmental Pseudomonas that inhibit not only
CF-derived P. aeruginosa but are effective against other pathogens
including ESKAPE pathogens and carbapenem resistant P. aeruginosa.
Overall, this research serves as a platform for the identification
of novel antibiotics from these environmental
isolates.

▼ Genetically modifying animals is a tool that can be used to increase livestock production. The
gene editing technology CRISPR has expanded the possibilities of
gene editing. The Cas9 nuclease creates a double strand break which can be repaired by non-homologous end joining (NHEJ) or homology directed repair (HDR). The goal of this experiment was to create a single nucleotide change using the CRISPR/Cas9 system in combination with a single strand oligo nucleotide (ssODN). The single nucleotide that was targeted occurred naturally in Holstein cattle, and is associated with increase milk production. There are multiple factors involved in the Holstein cow's ability to produce large amounts of milk. A mutation in the alpha lactalbumin sequence (α-LA) is one of these factors. The α-LA
gene sequence in some Holstein cattle contain an adenine the at (+15) position which corresponds to transcriptional start point of α-LA (+1), while other breeds have a guanine at that position. The adenine in the +15 position of the α-LA
gene has been associated with increased milk production. MAC-T cells and Angus fetal fibroblasts were transfected with a Cas9 plasmid, pSpCas9(BB)-2A-GFP, and a ssODN to insert the desired mutation. Using the CRISPR/Cas9 system we were able to create a double strand break resulting in indels and deletions at the (+15) site in MAC-T cells, but we were not successful in creating a single nucleotide change. However, we did see a single nucleotide change in Angus fetal fibroblasts using CRISPRs and ssODN. Following the success of inserting the mutation into a cell line we attempted to create an embryo containing the single nucleotide change using sperm-
mediated gene transfer (SMGT). Naked DNA binds naturally to sperm, and can be used to produce transgenic offspring in pigs and cattle. In this experiment, we analyzed methods to select thawed bovine sperm, and evaluated the binding of exogenous DNA to those sperm. Liposome preparation was done using a cationic lipid, 3-(trimethyl ammonium iodide) 1,2 dimystryl-propanediate (TAID) and a neutral lipid, L- Dioleoyl phosphatidyl-ethanolamine (DOPE) prepared according to given protocol. Percoll or swim-up methods were used to select sperm after thawing, followed by incubation (1h or 3h) with the liposome-DNA complexes. We used enhanced green fluorescent protein (eGFP) in combination with the liposomes as a marker for exogenous DNA binding. Five treatments per selection method were analyzed: 1) no incubation, no liposomes and no DNA, 2) incubation with no liposomes and no DNA, 3) incubation with liposomes and no DNA, 4) incubation with liposomes and 1 ng of DNA and 5) incubation with liposomes and 10 ng of DNA. Once the liposomes had been complexed with DNA they were incubated with sperm for one or three hours before IVF. The CASA results for total motility and rapid motility were significantly different from the control (P<0.01) between the control and the other treatments in the Percoll group as opposed to swim-up. These results confirm that the sperm selected with…

▼ The pluripotent characteristic of hematopoietic stem
cells (HSCs) makes them a good candidate for
gene therapy. The
safety drawbacks of the commonly used viral
gene transfer system
have made the search for alternative
gene transfer methods such as
non-viral or hybrid
gene transfer systems became increasingly
appealing in the field. One such system is the Sleeping Beauty (SB)
transposon-
mediated gene transfer system. Using a non-viral
approach to delivery SB plasmids we were able to significantly
increase the efficiency of stable
gene up to 20-fold higher than
previously published data by incrementally optimizing each element
of the SB
transposon system. In vivo studies demonstrated that
SB-modified human CD34+ cells were engrafted in NOD/SCID/yC(null)
(NSG) mice and differentiated into multi-lineage cell types with
stable transgene expression. Transgene expression remained
persistent in the secondary transplanted NSG mice indicating a
long-term stable integration achieved by HSB-
transposon system.
Non-integrating lentiviral (NIL) vectors were also investigated as
another method for SB plasmid delivery. Combining the stable
integration of the SB
transposon system with the delivery
efficiency of NIL, termed NILting beauty, could produce a hybrid
vector system that synergizes the advantages of both viral and
non-viral vector systems and provide a more effective and safer
approach to genetically modify HSCs. The feasibility and potential
of utilizing NILting beauty to achieve stable transgene integration
was evaluated using K562 and human HSCs. Up to 7% stable transgene
expression was achieved in K562 cells and around 1% for human CD34+
cells when transduced with NILting beauty vectors. The other
approach to increase long-term transgene expression with relatively
minimal adverse effects in clinical HSC
gene therapy is using
non-myeloablative conditioning regimen.; The feasibility of
combining busulfan with fludarabine as an alternative and
potentially more effective conditioning regimen was explored to
achieve long-term stable
gene marking in HSC
gene therapy. We
hypothesized that the addition of the immunosuppressive
chemotherapeutic agent fludarabine may contribute to better HSC
engraftment and long term transgene expression by reducing host
immunological responses to the foreign transgene product. To
evaluate this hypothesis, a clinically relevant infant rhesus
monkey bone marrow transplant (BMT) model was used. Preliminary
data showed a strong correlation between the busulfan dose and the
busulfan area-under-the curve (AUC). Transient neutropenia was
noted whereas lymphopenia was not observed. While monkeys with high
levels of eGFP
gene marking also showed detectable levels of
anti-eGFP antibodies when no fludarabine was given, they lacked
humoral immune responses to eGFP if they received fludarabine.
These data suggest that the immune responses against the transgene
may play a significant role in the successful outcome of HSC
gene
therapy and that fludarabine may be able to modulate these
responses. Since…
