▼ Malignant mesothelioma is an aggressive cancer of the
mesothelial lining causally linked to asbestos exposure and is
highly resistant to current therapies. We hypothesize a
stem/progenitor cell population is recruited to the tumor and
contributes to tumor cell growth and progression. Using an
orthotopic murine tumor spheroid model shown to recapitulate human
malignant mesothelioma, we identified a stem cell antigen-1 (Sca-1)
positive cell population recruited to tumor spheroids in vivo. The
Sca-1+ cell population was characterized by immunofluorescence
staining and flow cytometry. Candidate chemokines involved in
recruitment of this stem/progenitor cell population were identified
with SuperArrayTM, and confirmed with ELISA and transwell migration
assays. To test whether this recruited cell population contributes
to tumor cell proliferation, malignant mesothelioma cells were
grown in conditioned media from in vitro cultures and tumor cell
proliferation was assessed. To test whether this cell population
contributes to tumor progression in vivo, tumor cell-injected mice
were treated with chemotactic inhibitors and tumor burden was
assessed as compared to vehicle-injected control mice. The Sca-1+
cell population co-expresses markers for T lymphocytes,
hematopoietic stem cells and mesenchymal stem cells. The tumor
microenvironment expresses the chemokine SDF-1/CXCL12 and the
cognate receptor CXCR4 that are involved in recruitment of these
cell types. Involvement of the CXCR4/SDF1 chemotactic axis was
confirmed when transwell migration of mesenchymal stem cells to
lavage fluid was abrogated by treatment with small molecule
inhibitors of CXCR4. Once recruited, this stem/progenitor cell
population secretes factors that increase tumor cell proliferation.
In conclusion, a stem/progenitor cell population is recruited to
malignant mesothelioma spheroids, secretes factors that promote
tumor cell growth and is a potentially novel therapeutic
target.

▼ The serotonergic system regulates numerous behaviours and disruptions in this system have been associated with disorders of mood and mind. Although molecular genetic
analysis has dissected many of the genes involved in the specification of the serotonergic system, relatively little is known about the mechanisms that promote axonal outgrowth from serotonin-producing neurons and how these projections are directed to innervate and form synapses with their appropriate targets. The mouse
anorexia mutation causes hypersprouting of serotonergic projections in target fields and has provided us the unique opportunity to examine the crucial events that lead to the establishment of these complex serotonergic networks. Through positional cloning, I have identified a candidate gene that is upregulated during a time in which innervation and synaptogenesis of serotonergic neurons are maximal. I have assessed the expression of this candidate gene in the brain and have found striking differences in the pattern of expression between the normal and the mutant mouse. Furthermore, by using transgenic methods, I have partially rescued several hallmark behavioural phenotypes in the mutant mouse. Thus, this candidate almost certainly represents the
“Anorexia” gene.

▼ Studying vision in mice is a relatively recent
endeavor, with most research dating within the last 10 years. One
goal of this research is to examine similarities and differences
between the
mouse visual system and more traditional animal models.
This thesis contains two such studies, with the results from each
suggesting that the
mouse is a legitimate model for visual studies.
The first study examines orientation adaptation and demonstrates
that after orientation adaptation
mouse orientation tuning curves
shift similarly to what is observed in cats and primates. The
second study looks at contrast adaptation, and provides evidence
that it not spike rate dependent but rather pattern-specific.
Combined, these studies suggest that
mouse primary visual cortex
adjusts to its visual surroundings comparably to traditional animal
models, and also provide more of a foundation for future
experiments utilizing genetic tools that are only available in
mice.

▼ Krüppel-like factor 5 (KLF5) is a zinc-finger transcription factor known to have regulatory roles in the growth and differentiation of many adult tissues. In humans, KLF5 is located at 13q21-22, which is frequently lost in multiple tumour types, including tumours of the breast, endometrium, ovary and prostate where it is associated with loss of KLF5 expression. Little is known about the potential role of KLF5 in the haemopoietic system. Previous work by us and others has shown that KLF5 has a functional role in induction of differentiation of the myeloid compartment. In acute myeloid leukaemia (AML), our group has previously show that KLF5 expression is reduced relatively to normal CD34⁺ cells and that reduction of expression is associated with hypermethylation in intron 1. We also found that hypermethylation of KLF5 was associated with poor outcome, identifying KLF5 as an important target for further investigation in haemopoiesis and particularly the myeloid compartment. To extend the functional analysis of Klf5, an in vivo gene-ablation model was generated. As nonconditional Klf5 knockout mice (KO) die at embryonic day 8.5, pan-haemopoietic Klf5 conditional gene KO mice were generated by crossing Klf5fl/fl [fl/fl superscript] mice with Vav-cre transgenic mice. The Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] and Klf5fl/fl [fl/fl superscript] mice were analysed at 3, 9 and 12 month of age for defects in steady state haemopoiesis. Peripheral blood (PB) analysis of 9 and 12 month old mice revealed that Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] animals displayed significantly higher values for total white blood cell (WBC) count. To further characterise the changes in blood cell populations, flow cytometry was used with a range of different lineage antibody markers. The peripheral blood data indicated a decrease in the granulocytes of Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] mice as well as an increase in the T-cell compartment. Interestingly, we also showed that the Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] mice have increased numbers of blood and bone marrow eosinophils compared to Klf5fl/f [fl/fl superscript] mice. Consistently, we found significantly increased numbers of eosinophils in the lungs of Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] mice compared to Klf5fl/fl [fl/fl superscript] mice. The spleen weight of Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] mice was significantly higher compared to Klf5fl/fl [fl/fl superscript] mice. In addition, clonal assays conducted from the spleen of 9 and 12 month old mice showed a significant increase in colony number in the Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript]mice compared to Klf5fl/fl [fl/fl superscript] mice. This correlated with the flow cytometry data which showed a significant increase in haemopoietic stem cell (HSC) populations; short-term HSC (ST-HSC) and multipotent progenitor (MPP) in the spleen of Klf5fl/flVav-cre⁺ʹ⁻ [fl/fl superscript] mice. In summary, this study revealed multiple functional roles for Klf5 in haemopoiesis. Firstly, these studies demonstrated that as predicted…

▼ Ph.D. University of Hawaii at Manoa 2012.
Selenium is a chemical element that is an essential micronutrient associated with various aspects of human health. The biochemical activity of selenium is mediated by proteins, which incorporate it into the amino acid selenocysteine (Sec). There are 25 genes in humans encoding Sec-containing selenoproteins. The functionally characterized selenoproteins are oxidoreductase enzymes involved in cellular oxidation-reduction reactions. Most selenoproteins are expressed in the mammalian brain, and dietary selenium deficiency causes preferential retention in brain relative to other body organs. Further, dietary selenium deficiency and specific selenoproteins are associated with various brain diseases. Mouse models have been extensively used to study the function and handling of selenium in mammals. Genetic deletion of a Sec-rich protein in mice causes brain selenium deficiency, neurodegeneration and neurological impairment, and disruption of a phospholipid hydroperoxidase selenoenzyme causes rapid neurodegeneration. Therefore, selenoprotein expression and function promotes a healthy nervous system. However, selenium metabolism and the function of several selenoproteins in brain are not clearly defined. The overall purpose of this work is to clarify the function and utilization of selenium in the mammalian brain, to reveal implications for developmental and neurological diseases. The goal of these studies is to investigate changes in brain function and selenoprotein expression under conditions of altered selenium metabolism in mice. The research presented in this dissertation covers three major topics that are separated into chapters. To investigate selenium distribution in the brain, the neurological consequences of disrupting selenium transport and recycling in mice are assessed and compared. Disruption of selenium transport caused more profound neurological consequences than disruption of selenium recycling. To investigate potential functions of selenium in the nervous system, select selenoproteins were examined for cellular and subcellular expression in cells and brain tissue from transgenic and control mice. Select selenoproteins and synthesis factors were observed at synapses, suggesting localized expression and physiological relevance. To investigate a potential interaction between selenium and methamphetamine, expression profiling of selenoproteins in mouse brain after exposure to methamphetamine is described. Selenoprotein synthesis was adversely affected by methamphetamine administration in mice. These results confirm the importance of selenium in the mammalian brain.

▼ In this dissertation, I have explored the mechanisms underlying the selectivity of different visual features in the
mouse. I have compared these mechanisms to the canonical mechanisms for extracting these features. In chapter 2, I have demonstrated existence of nonclassical receptive fields in which the orientation preference can depend on the spatial frequency, in the
mouse visual cortex. I have compared the experimental data with a model based on random connectivity between cells which predicts existence of such receptive fields. In chapter 3, I have studied the input differences between V1 neurons with varying degrees of linearity in spatial summation. I have demonstrated evidence of connectivity which deviates from the standard hierarchical connectivity model. I show that nonlinear cells in the
mouse V1 can receive thalamic input which can itself be nonlinear and also orientation selective. In chapter 4, I have studied the development of binocular disparity tuning and using monocular deprivation. I show that disparity selectivity in the
mouse is reduced following contralateral eye deprivation during critical period. This effect is due to a disruption of existing disparity selectivity in the circuit following deprivation, as we observe no difference in degree of selectivity between adult animals and young mice before critical period. This disruption may be due to formation of new inputs which disrupt the matching between left and right eye existing inputs. We provide evidence for this by demonstrating a reduction in spatial acuity for the open eye inputs following deprivation. Across all of these studies, I demonstrate multiple instances in which the
mouse pathways differ from the classical early visual pathways. But I also find evidence for a distinctive connectivity, similar to the classical models. My thesis highlights the diversity in circuit computations which leads to the processing outcomes that are shared across the mammalian species

▼ Mouse embryogenesis is a paradigmatic example of regulative development, as embryos are able to compensate for alterations in the number of cells and to generate normal-sized pups. It was previously showed that double-sized embryos achieve downsizing after implantation but before gastrulation ensues. However, the exact timing and cellular mechanisms that regulate the morphogenetic events during double embryos development are still elusive. Here, we present a detailed morphological staging of post-implantation double-embryos, which reveals that size regulation occurs between E5.25 and E5.5, thus earlier than previously anticipated. At the same time, the embryonic tissue undergoes a process of epithelialization to form a lumen that later will become the pro-amniotic cavity, an essential morphogenetic event that is delayed in double embryos compared to normal-sized embryos. Mechanistic studies demonstrate that pro-amniotic cavity formation and size-regulation, albeit concomitant, have distinct molecular underpinnings. While size regulation is mainly achieved through lengthening of the cell cycle, lumenogenesis is dependent on programmed cell death in double embryos. In fact, increasing epiblast size results in a multi-layered epithelium in which multiple luminal cavities arise, whose fusion is mediated by apoptosis of inner cells lacking contact with the basement membrane. Taken together, this study furthers our understanding of how embryos compensate for increased cell numbers to achieve correct size and morphology.

Mechanisms behind the fate of early chromosomal and transcriptional heterogeneities in the mouse embryo.

▼ A series of events during the first four days of mouse embryo development leads to the formation of a blastocyst. The blastocyst consists of neatly segregated three lineages: the epiblast (EPI), which will form the fetus, the extra-embryonic primitive endoderm and the outer layer of the extra-embryonic trophectoderm (TE). This organization prepares the embryo for implantation and subsequent development. This study aims to explore two broad questions: 1) what mechanisms dictate the fate of the progenies of the chromosomally abnormal cells generated during the 4-8 cell stage division; 2) how the transcriptional heterogeneities between the blastomeres of the 4-cell stage embryo affect subsequent lineage segregation. A high incidence of aneuploidy in the early cleavage divisions is considered the principal cause for low human fecundity and developmental defects. However, there is a dramatic decline in the prevalence of aneuploidy as gestation progresses. To understand the fate of aneuploid cells, a mouse model of chromosome mosaicism was used. In vitro culture system and live imaging demonstrated that aneuploid cells were eliminated from the EPI by apoptosis both during pre- and peri-implantation development. Also, aneuploid cells displayed chronic proteotoxic stress. Subsequently, p53-mediated autophagy eliminated aneuploid cells from the EPI. Unlike aneuploid embryos, 1:1 diploid-aneuploid mosaic embryos show developmental potential equivalent to diploids. Their peri-implantation development was followed, and it was found that while aneuploid cells in the EPI underwent apoptosis, the diploid cells over-proliferated to regulate the overall EPI size. These results elucidate the cellular and molecular mechanisms used by mouse embryo to refine the EPI cell population and ensure only the chromosomally fit cells proceed through the development of the fetus. The second part of the study investigates into the early molecular players that bias cell fate decisions. Sox21 was earlier identified as the most heterogeneous gene at the 4-cell stage that can influence cell fate decision. The deep sequencing of Sox21 knockout and wild-type embryos was carried out at the 4-cell stage and compared. Klf2 and Tdgf1 were found to be important downstream targets of Sox21 that influence lineage segregation. Depletion of both these genes predisposed cells to the TE lineage. Co-overexpression of both these genes rescued the effect of Sox21 knockdown on cell fate. These results demonstrate the mechanism by which Sox21 heterogeneity, from as early as the 4-cell stage, biases cell fate. Together, these findings indicate the fundamental mechanisms used by mouse embryo to ensure developmental plasticity.

The role of Cdx in embryonic and adult mammalian hematopoiesis.

▼ All blood cells orginate from a common stem cell in the bone marrow: the hematopoietic stem cell (HSC), which is characterized by two main properties: self-renewal and multipotency. Hematopoiesis is a hierarchical system with the HSC at the top. During embryogenesis, hematopoietic cells and progenitors with broader potentials are progressively generated. Mammalian hematopoietic development begins in extra-embryonic structures and continues within the embryo proper. In the conceptus, the mesoderm is patterned along the anterior-posterior (A-P) axis. The positional identity of the mesoderm on the A-P axis is regulated by Hox genes. Cdx genes, another homeobox gene family, are required for the posterior growth of axial tissues during development. Cdx genes are known to act upstream of Hox. The first evidence for a role for Cdx in hematopoiesis was established in zebrafish. Using embryoid bodies, it was shown that the Cdx genes promote embryonic hematopoiesis in the
mouse by upregulating target Hox genes. Induction of Cdx4 promotes proliferation of hematopoietic progenitors. HSCs were more successfully derived from ESCs upon Cdx4 and Hoxb4 induction. Cdx gene deficiency jeopardizes embryonic hematopoiesis, with severe consequences for blood development upon Cdx2 mutations. As adult Cdx4 knockout mice only displayed minimal hematopoietic abnormalities, Cdx4 is dispensable for adult hematopoiesis. Previous studies on Cdx1 and Cdx2 mutants did not report any hematopoietic malformations either. However, it was demonstrated that overexpression of Cdx4 promotes leukemia in adult mice and that ectopic expression of Cdx2 is a key event in myeloid leukemia. The Cdx genes thus act as stimulators of hematopoietic progenitor maintenance and proliferation. Loss of function of Cdx impairs embryonic hematopoiesis, whereas gain of function in the adult bone marrow results in overproliferation of hematopoietic progenitors, which can instigate leukemia.

▼ This thesis provides the first scientific evidence of the photoprotective properties of rooibos
and honeybush herbal tea extracts and to some extent, two major honeybush polyphenols,
hesperidin and mangiferin. These properties were demonstrated using in vivo models by:
Providing evidence for the inhibition of tumour promotion by ultraviolet B (UVB)
radiation in a two-stage skin carcinogenesis mouse model. Topical application of
polyphenol-rich extracts of rooibos and honeybush prior to UVB tumour promotion of
7,12-dimethylbenz[a]anthracene (DMBA)-initiated mouse skin, inhibited the formation
of tumours. The rooibos and honeybush extracts decreased the incidence and volume
of the tumours. Topical application of hesperidin and mangiferin were less effective
than the honeybush extracts as only the tumour volume was decreased, but not the
incidence.
Providing evidence for the inhibition of photodamage of the skin by UVB exposure in a
mouse model. Topical application of polyphenolic rich extracts of honeybush prior to
UVB irradiation of mouse skin reduced erythema, peeling, oedema and hyperplasia.
The depletion of antioxidant enzymes catalase and superoxide dismutase (SOD) was
prevented. The extracts protected the skin from oxidative and direct DNA damage, and
reduced lipid peroxidation. The induction of cyclooxygenase-2 (COX-2) and ornithine
decarboxylase (ODC) was also reduced. Topical application of the polyphenols
hesperidin and mangiferin showed reduced protective effects compared to the extracts.
Suggesting the possible mechanisms by which honeybush and the polyphenols protect
against photocarcinogenesis such as reducing tumour promotion, inflammation and
oxidative stress.
Suggesting the benefits of including honeybush and rooibos as cosmeceuticals in skin
care products and sunscreens as part of the strategy for preventing skin cancer.
Discussing the recommendations for further study such as investigating more specific
chemopreventive activities of these two South African herbal teas and their
polyphenols, dose response studies and clinical evaluations.

▼ The project sought to examine the changes in the liver associated with porphyria and whether ATP binding cassette (ABC) transporters in the hepatocyte might in some manner be connected with the disruption of porphyrin homeostasis. The animal model of porphyria selected for the study was a genetic mouse model of porphyria cutanea tarda (PCT) that spontaneously develops the disorder with maturity. This model affords the opportunity to comprehensively evaluate liver changes without the administration of any exogenous compounds, which in other animal models are used to precipitate PCT. Many changes in hepatic parameters were present in the porphyric mouse model. Total liver heme concentration was increased, select cytochrome P450 activities were decreased while others were unchanged, UDP-glucuronosyltransferase activity was unchanged while glutathione S-transferase activity was elevated. Because of their broad and overlapping substrate selectivities, changes in specific transporters are most easily investigated through changes in mRNA expression.

▼ Recent evidence indicates that laboratory mice use elaborate ultrasonic songs, and this behavior possibly may be learned. In the present study, air pressure was manipulated while producing sound in isolated larynges from wild type male laboratory mice post mortem. The present study indicates that, consistent with findings in other mammals, changes in subglottal pressure induce linear changes in the fundamental frequency of periodic sound, sudden non-linear frequency jumps, biphonation, and sudden changes from periodic to aperiodic sound depending on the absolute value of air pressure applied. The linear and non-linear changes in phonations by the isolated mouse larynx cover virtually all aspects of natural vocalizations produced by adult male mice. Data from simulated contractions of the main laryngeal muscle for frequency control, the cricothyroid, suggest that adduction of the thyroid plays only a minor (if any) role for frequency control in the mouse larynx, especially when compared with the larynx of bats. Therefore, most spectral aspects of mouse vocalizations appear to be based upon changing the tracheal air flow rather than contracting the cricothyroid muscle.

▼ CECR1 (cat eye syndrome chromosome region, candidate
1) is located on chromosome 22q11.2. Duplication of this region
results in the human disorder cat eye syndrome (CES), which
includes a variety of heart defects. CECR1 is suggested to be
dosage sensitive, based on a predicted role in controlling
extracellular adenosine level during development, and thus may be
responsible for some of the CES features, including heart
abnormalities. Animal models were established to study the effect
of overexpressing CECR1 in hearts. Abnormal phenotypes in hearts
were not detected in zebrafish embryos overexpressing zebrafish
cecr1. Thinner right ventricular walls and atrioventricular (AV)
valve disorganization were observed in embryos of the transgenic
mouse line FVB/N-Tg(MHC-hCECR1), which expressed human CECR1
specifically in cardiac muscle. The observed phenotypes were not
typical of patients with CES; however, disrupted adenosine level
resulting from increased adenosine deaminase activity might be
responsible for the phenotypes.

▼ Osteoarthritis (OA) is the leading cause of disability among the elderly population, affecting approximately 27 millions Americans and costing $60 billion in related-health care costs.
Mouse models of OA have been developed to study the mechanisms of OA and therapeutic interventions. However, traditional animal models induce OA pathology through traumatic surgeries, which only represent 10% of human OA patients. Thus, in this thesis, a novel noninvasive OA
mouse model was developed, characterized, and applied to transgenic mice. The changes in articular cartilage and subchondral bone were analyzed by histology, immunohistochemistry, and microcomputed tomography. To develop a noninvasive OA
mouse model, an in vivo tibial loading model was used to investigate the adaptive responses of cartilage and bone to mechanical loading and to assess the influence of load level and duration. Peak cyclic compression of 4.5 and 9.0N was applied to the left tibia via the knee joint of adult (26-week-old) male mice for 1, 2, and 6 weeks at 1200 cycles/day. In addition, 9.0N loading was utilized in young (10-week-old) mice. Loading promoted cartilage damage, cartilage thinning, and subchondral cortical bone thickening in both age groups. Both age groups developed periarticular osteophytes at the tibial plateau in response to the 9.0N load, but no osteophyte formation occurred in adult mice subjected to 4.5N load. Development of a novel noninvasive loading model was followed by investigating the traumatic vs. nontraumatic nature of cyclic loading of the
mouse knee joint. To differentiate traumatic tissue damage versus cell-mediated processes in the development of OA pathology, a single nondestructive 5-minute loading session was applied to the left tibia of adult (26-weekold) mice at a peak load of 9.0N. Knee joints were subsequently analyzed at 0, 1 and 2 weeks after loading. At T = 0, no change was evident in cartilage or subchondral bone. However, cartilage pathology demonstrated by localized thinning, proteoglycan loss, and inhibition of chondrocyte autophagy occurred at 1 and 2 weeks after the single session of loading. Transient cancellous bone loss was evident at 1 week, associated with increased osteoclast number, reversed at 2 weeks. Finally, the in vivo tibial loading model was implemented to study the role of Dickkopf1, an inhibitor of the Wnt pathway, in the development of load-induced OA. To identify the role of Dickkopf-1 protein in OA, novel viable mice with Dickkopf-1 knockout and Wnt3 knockdown (Dkk1-/-;Wnt3+/-) were used. The left tibia of 10-week-old Dkk1-/-;Wnt3+/- and respective control groups, littermate control (Dkk1+/+;Wnt3+/+) and Wnt3 knockdown (Dkk1+/+;Wnt3+/-) mice, underwent cyclic compression at a peak load of 9.0N for 2 weeks. As a result of loading, both Dkk1-/-;Wnt3+/- and Dkk1+/+;Wnt3+/+ mice demonstrated cartilage erosion, subchondral cancellous bone loss, and osteophyte formation. However, Dkk1+/+;Wnt3+/- mice did not undergo cartilage degeneration and showed limited osteophyte formation, indicating…

▼ Normal spermiogenesis requires the transcription of many genes that occurs exclusively after meiosis. This wave of transcriptional changes in haploid spermatids is well-documented, but the underlying mechanisms of regulation are not. Deficiency of the dual bromodomain-containing protein BRWD1 has already been shown to be important for both male and female fertility. Here I show that nearly 300 transcripts, most of which are spermatid specific, were downregulated in Brwd1-/-mutant testes. There was nearly complete elimination of transcripts encoding proteins important for spermiogenesis, such as the protamines and transition proteins. However, the misregulation was not associated with global epigenetic changes in chromatin, suggesting that BRWD1 acts selectively upon certain haploid-expressed genes. Our collaborators showed that Brwd1 deficient oocytes, on the other hand, do not have any differences in transcript levels but display a two-fold increase in LINE1 expression. Despite BRWD1's expression in development, infertility is the only clear phenotype in Brwd1 mutants. I found that mice doubly mutant for Brwd1 and its paralog Phip were phenotypically indistinguishable from Phip-/- mice, indicating perhaps that another paralog, the X-linked Brwd3, may be functionally redundant to them in the soma.

▼ Pancreatic beta cells are the only cell type in the body that can produce insulin, a hormone required for maintaining glucose homeostasis. Type 1 and type 2 diabetes result from an absolute or relative reduction in functional beta cell mass, respectively. One approach to replacing lost beta cell mass is transplantation of islets from cadaveric donors; however, this approach is limited by lack of adequate amounts of donor tissue. Therefore, there has been much interest in identifying factors that enhance beta cell differentiation and proliferation in vivo or in vitro. Connective tissue growth factor (CTGF) is a secreted molecule expressed in pancreatic endothelial cells, beta cells, and ducts during pancreas development. CTGF is required for proper lineage allocation and islet morphogenesis during development and for beta cell proliferation at late gestation. The current study investigated the tissue interactions by which CTGF promotes normal pancreatic islet development. These results show that CTGF produced by both endothelial cells and beta cells is required for embryonic beta cell proliferation, making CTGF the first identified secreted endothelial-derived or beta cell-derived factor which regulates embryonic beta cell proliferation. Removing CTGF from any one source in the pancreas impairs embryonic beta cell proliferation, indicating that beta cell proliferation is particularly sensitive to the level of CTGF. In contrast, inactivating CTGF from one source in the pancreas does not affect lineage allocation or islet morphogenesis, indicating that these sources of CTGF act redundantly to promote these processes. This dissertation also demonstrated that over-expression of CTGF in beta cells during embryogenesis using an inducible transgenic system increases islet mass by promoting endocrine cell proliferation. Together, these findings demonstrate that CTGF acts in both an autocrine and paracrine manner during pancreas development and suggest that CTGF has the potential to enhance beta cell proliferation or differentiation in diabetic models.

MOUSE MODELS OF PROSTATE CANCER PROGRESSION AND BONE METASTASIS

Dissertation under the direction of Robert J. Matusik, PhD
Prostate cancer is the second leading cause of deaths due to cancer in men in the United States. The American Cancer Society has projected that 192,280 new cases and 27,360 deaths will occur in the year 2009. Mostly, men over the age of 50 are afflicted by the disease and more than 70% of the men diagnosed with prostate cancer are over the age of 65. Most of the patients who suffer from prostate cancer do not die due to the tumor at the primary site but rather due to complications when the tumor has spread to the bone. It is estimated that each year, about 350,000 people die of bone metastasis in the United States. The causative tumor becomes incurable once the bone has been invaded and only 25% of prostate cancer patients are able to live 5 years subsequent to their diagnosis of bone metastasis. The interaction between prostate cancer cells and the bone creates a vicious cycle of bone formation and bone destruction thereby destabilizing the inherently delicate homeostasis within the bone. In prostate cancer, this process leads to metastatic lesions that are predominantly osteoblastic. However within the background of bone formation, several groups have reported that bone resorption is an integral part of prostate cancer bone lesions. Therefore, early detection and treatment before the tumor metastasizes is critical for the survival of the patient.
Creating and characterizing
mouse models that better mimic the progression in human prostate cancer is a powerful tool to study and delineate the various steps in tumor progression. Most of the currently available
mouse models of prostate cancer successfully recapitulate the early steps of tumor progression in the primary site but fail to metastasize to other organs especially to the bone. Amongst the existing ones, transgenic models that are created by dysregulating a gene that is widely known to be altered in human prostate cancer are considered to be more reflective of the human disease. This is in contrast to transgenic
mouse models that overexpress the small t and large T antigens that despite the phenotype they produce, are considered to have little physiological significance.
This first part of the thesis describes the creation and characterization of the hepsin/myc bigenic model that develops adenocarcinoma in the primary site. The second part of the thesis describes a model that delineates the interactions between prostate cancer cells and the bone microenvironment. This is approached by dysregulating the T-box transcription factor Tbx2 in PC3 human prostate cancer cells and looking at the effect of this dysregulation on the interaction of the cells with the bone microenvironment.

▼ Theiler??s murine encephalomyelitis virus (TMEV) can infect the central nervous
system (CNS) and cause neurological damage. The exact route by which TMEV enters
the CNS remains unknown. Two hypotheses suggest that TMEV enters the CNS either
by the neural and/or the hematogenous pathway. To explore these hypotheses, the
GDVII strain of Theiler??s virus was inoculated via different routes in susceptible mice.
The incidence of paralysis and/or encephalitis was evaluated. The forms of paralysis
displayed corresponded to the site of viral inoculation. Following intramuscular (i.m.),
intraperitoneal (i.p.), intravenous (i.v.) and footpad routes of injection, bilateral and or
contralateral paralyses were observed. In mice injected intratongue, tongue paralysis
was observed. Intracranial (i.c.) injections resulted in 100% mortality. A detailed time
course experiment was also completed which focused on the neural transport pathway
used by TMEV to invade the CNS. The GDVII strain of Theiler??s virus was injected
into the left gastrocnemius muscle and the hypoglossal nerve (CN XII). The incidence
of paralysis and/or encephalitis was evaluated on the basis of clinical signs,
immunofluorescent analysis, and histopathology. Following the i.m., route of injection,
unilateral hind limb paralysis was observed in the injected limb and a weakening of the contralateral limb was also observed. In mice injected in the hypoglossal nerve, tongue
paralysis was observed. Also, the penis of most affected males was prolapsed. The
localization of viral antigen using fluorescent labeling correlated with the clinical signs
of paralysis for both injections. The studies reported here support the theory that GDVII
Theiler??s virus may gain access to the CNS through a neural transport pathway.

▼ Mapping the microvascular networks in the brain can lead to significant scientific and clinical
insights. The recent advances of high-throughput physical sectioning light microscopy have
greatly contributed to reducing the gap in neuroimaging between large-scale, low-resolution techniques
and small-scale, high-resolution methods. The Brain Networks Laboratory at Texas A&M
University developed a serial sectioning microscopy technique called the Knife-Edge Scanning
Microscopy (KESM) to section and image the entire
mouse brain at submicrometer resolution.
The KESM can be used to obtain information about a small animal organ, such as a whole
mouse
or rat brain, at submicrometer resolution of 0:6 μm 0:7 μm 1:0 μm voxel size. In our effort to
map the entire vascular network in the
mouse brain, the Brain Networks Laboratory perfused the
mouse brain vessels with India ink, and used the KESM to image the prepared brain.
However, the image data size of the entire
mouse brain from the KESM is about 1.5 TB,
and is not easy to handle or analyze. Moreover, the dataset contains unintended noise from the
serial sectioning process. Because of these difficulties, previous studies partially analyzed the
structure of the
mouse brain by manually selecting a small, noise-free portion (volume size under
1000 1000 1000 voxel) in the dataset. In addition to the KESM dataset, there have been
studies for vessel reconstruction and analysis of the whole
mouse brain at lower resolution or of
partial brain regions at submicrometer resolution. However, to the best of our knowledge, there has
been no study for vessel reconstruction and analysis of the whole
mouse brain at submicrometer
resolution.

▼ Fragile X Syndrome (FXS) is a neurodevelopmental disorder and the most common heritable single gene cause of Autism Spectrum Disorder (ASD). The Fragile X (FMR1-KO) mouse model has been used to understand the pathophysiology of the disease. However, the majority of studies have been done in adult mice and early life outcomes have yet to be explored. Therefore, in order to contribute to the knowledge of the neurodevelopmental processes associated with brain disorders, this thesis examines postnatal outcomes in the Fragile X Mouse Model: early life behaviours, the developmental trajectory of a set of ASD risk genes, and neuroanatomical phenotype. The first study examined ultrasonic vocalizations in pups and showed a transient increase in calls in FMR1-KO mice. To understand the relationship between early life behaviours, the second study examined outcomes in the pre-pubertal period in these mice when challenged with lipopolysaccharide and maternal separation. The results showed genotype and treatment interactions affecting sexually dimorphic behavioural outcomes and developmental milestones. In the third study, possible underpinnings of behavioural differences were explored by examining mRNA expression of the neuroligins and neurexins. In FMR1-KO mice, changes were transient and sex-specific, suggesting these as molecular effectors in the disease. Lastly, using structural brain imaging, the fourth study examined regional volume differences that may be related to behavioural differences. Differences in regions affected in FXS patients were observed and genetic background was shown to affect the neuroanatomical phenotype. Overall, this thesis demonstrates that the FXS model recapitulates some outcomes in other ASD mouse models and shows that this single gene has multiple interactions with sex, strain, and postnatal challenge which manifests at specific ages at molecular, brain structure and behavioural levels. This work contributes to the efforts elucidating the neurobiology of ASD and reverse translation approaches to identify therapeutic targets for neurodevelopment disorders.

Autism spectrum disorder (ASD) is a diagnosis based on observed behaviours: impaired communication and repetitive actions. However, there are genetic and other behavioural differences in ASD patients that are not shared among the group. It is important to tease apart this group since current treatments for ASD do not target the biological problems or the core impairments. This thesis focuses on Fragile X Syndrome, the leading genetic condition that results in ASD in order to understand the biological basis of ASD. Using a mouse model, compared to healthy mice, these studies report changes in behaviours, in the size of different brain regions, and in molecules involved in connecting brain cells during development. These findings shed light on the molecular story underlying ASD. By understanding the nature of influences on the developing brain, the type and timing of interventions can be designed to…

▼ Since the discovery of the p120ctn binding partner, Kaiso, a BTB/POZ transcription factor, several studies have implicated the protein in both development and tumourigenesis. Most information about Kaiso’s function in vertebrate development has been gleaned from studies in Xenopus laevis embryos where Kaiso negatively regulates the Wnt signalling pathway. Since the Wnt signalling pathway is crucial in intestinal development, intestinal-specific Kaiso overexpressing mice were generated and characterized to elucidate Kaiso’s role in a mammalian context. Kaiso transgenic (KaisoTg/+) mice were viable and fertile but developed gross histopathological changes in the small intestine. The KaisoTg/+ mice exhibited enlarged crypts accompanied by increased secretory cell differentiation reminiscent of inhibition of the Notch pathway. Indeed, the Notch effector protein, HES1, is decreased in KaisoTg/+ mice. Additionally, KaisoTg/+ mice display a neutrophil-specific intestinal inflammation reminiscent of the knockdown of p120ctn. Interestingly, the KaisoTg/+ mice display decreased p120ctn localization at the membranes and an increase in the neutrophil adhesion molecule, ICAM-1, both of which induce neutrophilia. Notably, the KaisoTg/+ mice developed multiple crypt abscesses over time due to massive neutrophil infiltration of the epithelial cell layers. This is the first study to examine the in vivo roles of Kaiso in a mammalian context and our findings suggest a regulatory role for Kaiso in the inflammatory and Notch signalling pathways.

▼ Recently, the World Health Organization estimated that chronic diseases are responsible for 46% of disease occurrence and 59% of all deaths worldwide. Growing evidence suggests that increasing chronic disease incidence is dependent upon several factors, including inadequate consumption of antioxidant-rich fruits and vegetables and chronic inflammation. Many researchers have previously investigated potential health benefits associated with consuming plant-based foods, and the ability of these foods to prevent or suppress the pathologies linked to chronic diseases. Specifically, plant-based bioactive compounds called polyphenols have been widely studied, and show promise as a therapeutic agent against chronic diseases.
Tea is produced from the leaves of the Camellia sinensis plant and, aside from water, is the most popular beverage in the world. Green tea, black tea, and oolong tea are the three major types of commercially produced tea. Black tea comprises over 75% of global tea production and consumption, followed by green tea at approximately 20%, and oolong tea at less than 2%. For centuries, tea has been known for its health effects. It has historically been used as a medicine in China and Japan. Tea polyphenols are particularly thought to have chemopreventive and cardioprotective effects due to their antioxidant and anti-inflammatory properties. Previous in vitro and animal studies have analyzed the anti-inflammatory activity of polyphenols, and the specific mechanisms by which these compounds suppress inflammation. But, to our knowledge, few studies have investigated tea’s anti-inflammatory capacity as a whole food, or compared the potential anti-inflammatory effects of different tea types.
Therefore, the objectives of the following study were to evaluate total phenol content in green tea (GT) and black tea (BT); to assess viability of cells exposed to GT, BT, and LPS; and to measure the modulation of inflammatory responses in lipopolysaccharide (LPS)-induced RAW 264.7
mouse macrophages by GT and BT. We predicted that GT and BT would differentially modulate inflammation because of differences in composition.
First, the total phenolic content in commercially produced GT and BT was measured using the Folin-Ciocalteu method. Freshly prepared GT had a significantly higher phenolic content than freshly prepared BT (1317.1 + 6.0 GAE, 918.9 + 10.7 GAE). Stored at -80° C, the phenolic content of GT and BT significantly increased at one month (1770.0 + 35.2 GAE, 1124.0 + 19.1 GAE) and two months post-preparation (1587.2 + 21.5 GAE, 1003.2 + 8.6 GAE), then decreased at 3 months post-preparation (1407.8 + 13.4 GAE, 941.8 + 0.5 GAE) (p < 0.05).
The second goal of our study was to assess viability in RAW 264.7 cells treated with GT, BT, and LPS. Viability was colorimetrically determined by the Trypan Blue assay and by measured absorbance values from the MTT assay. The GT, BT, and LPS treatments did not produce a cytotoxic effect, and cell viability values for each treatment were not significantly…

▼ Cell-based therapy is a promising treatment option for
central nervous system (CNS) disease and injury, but therapy
strategies require optimization to achieve clinical improvement.
The primary motivation of this thesis is to gain knowledge of in
vitro neuronal differentiation of stem cells and to develop
three-dimensional (3D) culture models to investigate stem cell
transplantation to the CNS. The first study in this thesis
addressed the heterogeneity of
mouse embryonic stem cell-derived
dopamine neurons. In vitro, the percentage of calbindin+ subtype of
DA neurons was higher than the calretinin+ subtype, which was a
similar trend to in vivo. In addition, dopamine neuron subtype
generation in vitro was not governed by exogenous sonic hedgehog
and fibroblast growth factor 8. In the second study, we developed a
scaffold-free, 3D neural spheroid culture using primary rat
cerebral cortex cells. Cortical cells in agarose hydrogels
containing round-bottom microwells self-assembled into spheroids.
The 3D neural spheroids recapitulated key in vivo-like features
including 3D neuronal and astroglial network formation,
extracellular matrix production, electrical activity, circuitry
formation via excitatory and inhibitory synapses, and brain-like
mechanical properties. These physiologically relevant
characteristics make these spheroids an effective in vitro model
for the CNS. In the third study, we expanded the 3D culture
technique to develop an in vitro model for stem cell
transplantation to the CNS. To represent the host CNS tissue in
vitro, trampoline-shaped 3D microtissues were fabricated using
cortical cells. Neural stem cells (NSCs) in the form of spheroids
were placed in the center of the CNS host trampoline microtissues,
and NSC behavior in this transplantation model construct was
monitored. In a proof-of-concept experiment, we utilized this model
to test the effect of fibroblast growth factor 2 on NSC migration.
Based on the microtissue characterization results, this 3D in vitro
transplantation model has the potential to generate more
translatable results than 2D co-culture platforms. These works
together contribute to a deeper understanding of in vitro
generation of neurons and provide a novel in vitro 3D engineered
CNS model for the investigation of cell-based
therapies.

▼ Kinesiology research has shown that translation and rotation are inseparable actions in the real world. Motivated by this fact, this thesis explores a model for the computer
mouse, the new addition being rotational input about vertical axis of a
mouse. We realize our model through Mushaca, a 3-degrees-of-freedom
mouse (3DOF
mouse) that can sense rotation, in addition to sensing XY planar translation. The thesis presents two realizations of Mushaca - namely a MEMS version that uses accelerometer and gyroscope, and an optical sensor version that uses two optical sensors. Through a controlled user study we try to find out if that rotation is an useful input modality in pointing devices. The user study shows that in general rotation is a useful input modality, but it excels a standard
mouse only in certain scenarios. Through the user study we also study the effect of the rotating coordinate system of the
mouse and also how users adapt to this changing frame of reference through kinesthetic learning.

▼ Clinical cases of bovine mastitis are most severe in the early stages of lactation. The causes of this increased propensity for severe mastitis during early lactation, compared to mid and late lactation are unclear. In order to better understand the early lactation immune response to mastitis, a murine model of mastitis was employed. Intramammary inoculation of a mastitis causing Escherichia coli strain was performed in lactating mice at various stages of lactation to model the immune response seen in cows during lactation. In our experiments, mice in the early stages of lactation exhibited altered mRNA expression of cytokines IL-1β, IL-6, IL-10, and TNFα over the course of infection when compared to mice at mid lactation. Additionally, increased bacterial growth was observed in the mammary gland of mice infected during early lactation compared to late lactation. These results are consistent with the immune response observed in cows at early lactation. These results suggest that the mouse may provide a useful model to study differences in the immune response seen during different times in lactation.

▼ Background: Periodontal disease is an inflammatory disease that increases in prevalence with increasing age. The elderly demonstrate an elevated and dysregulated inflammatory response. Macrophages act as a key regulator of inflammation. The study aim was to evaluate the extent to which age-related changes and chemical inhibition in the macrophage affect periodontal disease in a mouse model. Methods: Old (24 month) and young (3 month) mice were utilized for this study. Periodontal status was examined in mice at baseline. Periodontal disease was induced via Porphyromonas gingivalis (P. gingivalis) inoculated ligatures in old and young mice for 7 days. A second cohort had disease induced for 7 days, followed by ligature removal, and recovery for 7 additional days. Half the mice in each induction or recovery group were treated with Pexidartinib (PLX), which inhibits macrophage recruitment. Linear bone loss, alveolar bone volume, and macrophage quantification were examined by t test.Results: PLX successfully inhibited macrophage numbers in all treatment groups. The young periodontal disease group had significantly more vertical bone loss (0.234±0.024mm) compared to the young periodontal disease PLX group (0.140±0.023mm)(p≤0.001) and less alveolar bone volume (0.460±0.016BV/TV) compared to the young periodontal disease PLX group (0.586±0.004BV/TV)(p≤0.001). The old periodontal disease group exhibited no difference in vertical bone loss (0.242±0.025mm) compared to the old periodontal disease PLX group (0.238±0.032mm)(p=0.825) and significantly less alveolar bone volume (0.536±0.030BV/TV) compared to the old periodontal disease PLX group (0.614±0.030BV/TV)(p≤0.01). The young recovery control group trended towards less vertical bone loss (0.170±0.020mm) compared to the young recovery + PLX group (0.190±0.011mm)(p=0.055) and had no difference in alveolar bone volume (0.557±0.015 BV/TV) compared to the young recovery PLX group (0.545±0.011 BV/TV)(p=0.131). The old recovery control group exhibited no difference in vertical bone loss (0.241±0.019mm) compared to the old recovery PLX group (0.218±0.035mm)(p=0.187) and had significantly less alveolar bone volume (0.567±0.021BV/TV) compared to the old recovery PLX group (0.617±0.023BV/TV)(p≤0.01).Conclusion:PLX prevents periodontal disease induction in old and young groups and improves recovery in older age groups. The difference in response during recovery could suggest that there are age related changes in the macrophage that affect disease progression.

▼ The New Zealand Black (NZB) mouse chromosome 13 (c13) is linked to development of autoimmunity. B6 mice containing a portion of NZBc13 (B6.NZBc13 (c13)) develop a lupus phenotype that includes: autoantibody production, increased B and T cell activation, and marginal zone B cell and myeloid dendritic cell expansions. c13 mice have a B cell intrinsic dsRNA-sensing defect, leading to increased TLR3 expression and survival. The role of the aberrant dsRNA sensing in the generation of the c13 autoimmune phenotype was assessed by generating c13 mice with TLR3 knocked out (c13.TLR3KO). Marginal zone B cell expansion and B cell activation were attenuated in c13.TLR3KO mice, but other cellular phenotypes were not affected. Autoantibody production was partially reduced. These results indicate that altered dsRNA-sensing contribute to a portion of the altered cellular phenotypes in c13 mice, but that other susceptibility loci in the c13 interval are required for full development of autoimmunity.

▼ Les myopathies congénitales sont des maladies génétiques rares touchant les muscles qui ne possèdent pour le moment pas de traitement curatif. Elles se manifestent par une hypotonie et une faiblesse musculaire généralisée pouvant entrainer le décès précoce des patients. Parmi elles, on retrouve la myopathie à némaline (NEM3) causée par des mutations dans le gène de l'alpha-actine (ACTA1) et la myopathie myotubulaire (XLMTM) liée à MTM1, qui se caractérisent respectivement du point de vue histopathologique par la présence d'agrégats protéiques et de noyaux en position centrale dans les fibres musculaires, et dont les mécanismes physiopathologiques sont encore mal connus.Dans ce projet de thèse, j'ai étudié la physiopathologie de la NEM3 grâce à l'analyse du transcriptome des muscles du modèle murin porteur de la mutation p.H40Y dans Acta1 (KI(Acta1)H40Y). Ainsi, plusieurs voies de signalisation ont été révélées comme étant dérégulées, notamment celles contrôlant la masse musculaire et la transmission synaptique. J'ai analysé la morphologie et fonction des jonctions neuromusculaires (JNM) et mis en évidence une fragmentation de celles-ci, associée à des altérations ultrastructurales et moléculaires, et une fatigabilité accrue du muscle mutant lors d'une stimulation nerveuse électrophysiologique répétée, ce qui pourrait ouvrir des perspectives de traitement pharmacologique. Parallèlement, j'ai aussi exploré des stratégies de thérapie génique pour cette myopathie. Mes résultats ont montré que l'administration intramusculaire et intraveineuse de virus adéno-associés recombinants (AAVr) exprimant le transgène ACTA1 sous le promoteur de la desmine ou du cytomégalovirus n'a pas permis d'améliorer le phénotype des souris KI(Acta1)H40Y. Ainsi, j'ai mis au point une autre approche consistant à réduire l'expression de l'ARN messager d'Acta1 et sélectionné in vitro des séquences siARN ayant la meilleure spécificité pour l'allèle muté. L'injection intramusculaire de vecteurs AAV exprimant des shARN ciblant le transcrit d'Acta1 muté chez le modèle murin n'a cependant pas montré de signes d'amélioration de la pathologie, mais plutôt une importante réaction immunitaire. Mes résultats indiquent donc qu'une optimisation de ces stratégies de thérapie génique sera nécessaire pour corriger la maladie.D'autre part, dans le contexte de la myopathie myotubulaire, j'ai participé au développement d'une approche thérapeutique visant à diminuer le niveau d'expression de la dynamine 2 dans les cellules musculaires en utilisant des oligonucléotides antisens (vivo-morpholinos). Des mutations dans le gène de la dynamine 2 (DNM2) sont responsables de la forme autosomique dominante de myopathie centronucléaire et la neuropathie de Charcot-Marie-Tooth de type DI-CMT2B; de plus, la surexpression de DNM2 est impliquée dans le mécanisme physiopathologique de la myopathie myotubulaire. Nous avons montré que l'administration intramusculaire de vivo-morpholinos chez le modèle murin de XLMTM (KO-Mtm1) permet d'améliorer la pathologie, avec une augmentation de…

▼ Multiple-mouse MRI (MMMRI) accelerates biomedical research by imaging multiple mice simultaneously. To date, MMMRI has been explored in three ways: shielded transmit-receive coils, shielded transmits coil with separate unshielded receive coils; and finally shielded transmit-receive coils with independent gradient coils. However alternative transmit coil configurations and possible benefits of eliminating shielding have not yet been explored. The goal of this thesis is to test possible radiofrequency configurations with and without shielding for the purpose of improving image quality for MMMRI. Results demonstrate that using an unshielded transmit-receive coil array provided a 20% improvement over an identical shielded coil. A new unshielded 7-coil MMMRI array is presented, minimizing the ghosting between image overlap using mutual inductance minimization and a sensitivity encoding (SENSE) reconstruction. The final array provided high resolution images (90µm) of up to seven live mice simultaneously with appropriate signal-to-noise for automated analysis.

Mechanical and material property changes in bone with experimental diabetes: a murine model.

▼ Over 23 million people in the United States are plagued by diabetes mellitus. Studies have shown that those with diabetes have a higher occurrence of bone fractures than those without the disease, but risk factors associated with diabetes account for only a portion of these fractures (Schwartz 2003; Vestergaard 2006). This implies that there are properties of diabetic bones that account for this increase in fractures. Research has been performed on the bone mineral density (BMD) of those with and without diabetes. However, studying this singular property of bones does not fully explain the increase in bone fractures in the diabetic population. Additionally, this research has yielded inconclusive results: some studies show that diabetes leads to an increase in BMD while others show a decrease in this property (Krakauer et al. 1995; Retzepi & Donos 2010). The objective of this study is to analyze the effect of experimental diabetes on bone properties in mice. This relationship is explored through analyzing different
mouse strains to determine a potential genetic link, kidney removal to mimic the effects of nephropathy, and an LXR agonist to explore a potential diabetes treatment. We hypothesize that diabetes will negatively impact bone properties across multiple strains of mice, kidney removal will further degrade bone properties and the LXR agonist will improve some of the negative bone effects that diabetes causes. In general, STZ-induced diabetes was accompanied by decreases in physical and compositional bone properties in both strains of mice. Kidney removal and treatment with an LXR-agonist had little to no effects on these bone properties. Kidney removal was performed in skeletally mature mice; this old age may have contributed to the lack of effects. Similarly, the LXR agonist was administered over a short time period, and the detrimental effects from the diabetes were not able to be overcome. The data presented here provides evidence that experimentally-induced diabetes corresponds with a decrease in bone properties and nephropathy. While LXR agonists hold promise for mitigating bone property changes in diabetes, further analysis is required to determine their potential effects.
