▼ The prevalence and incidence of obesity and related co-morbidities such as insulin resistance and type two diabetes mellitus (T2DM) are rapidly increasing world-wide. These health burdens negatively impact individuals, families, the community and the government, for a multitude of reasons. The search for suitable therapeutic targets for obesity, in combination with a healthy diet and increased physical activity is a strategy for weight management and associated co-morbidities such as T2DM.
The endocannabinoid system is a lipid derived signalling system that is modulated by different dietary fatty acids and has a role in regulating energy homeostasis. Modulation of cannabinoid receptor 1 (CB1) reduces whole body adiposity and increases oxidative capacity within the skeletal muscle. The skeletal muscle is a major contributor to whole body energy metabolism through the oxidation of fatty acids, insulin signalling and glucose uptake, therefore understanding the impact that endocannabinoid
pharmaceutics have on this tissue is essential. Putative endocannabinoid receptors including G Protein-
Coupled Receptor (GPR55) and G Protein-Coupled Receptor 18 (GPR18) may potentially be beneficial pharmaceutical targets for obesity and associated co-morbidities. GPR55 expression is upregulated in visceral adipose tissue in obesity and T2DM. Surprisingly GPR55 knockout mice have increased adiposity and reduced physical activity. While GPR18 has been shown to be expressed in adipose tissue, its role in obesity is unknown. Furthermore the role that atypical cannabinoid
compounds, O-1602 or O-1918 (which have/ are hypothesised to have affinities for these receptors
and therefore modulate these putative cannabinoid receptors) have in obesity and skeletal muscle homeostasis, following chronic treatment has yet to be determined.
The dietary intake of specific fatty acids can also alter circulating endocannabinoid concentrations depending on the type of fatty acid consumed. The effect that different dietary fatty acids have on the putative cannabinoid receptors GPR55 and GPR18 and whole body energy homeostasis in obesity is unknown.
Therefore the overall focus for this thesis was to determine the role that atypical cannabinoids have on homeostatic skeletal muscle signalling and whole body energy metabolism in obesity. In addition to this, the effect that different dietary fatty acids have in obesity and whole body energy metabolism were also determined, which may partially be attributed to GPR55 and GPR18 signalling.

▼ Strigolactones (SLs) are plant hormones and rhizosphere-signalling molecules that control plant architecture and environmental adaption, promote symbioses with soil organisms, and mediate root parasitism. These diverse activities give SLs great promise as agrochemicals, with potential applications in optimising plant architecture, controlling parasitic weeds, enhancing nutrient uptake, and improving tolerance to drought and salinity. However, agricultural use is currently unfeasible as there are no economically viable sources of SLs or SL analogues. Microbes engineered for SL biosynthesis could provide a cheap, renewable, and scalable production method that could overcome current supply challenges, and enable SLs to be deployed as agrochemicals.Synthetic biology – characterised by modularity, standardisation, interoperability of biological parts, and engineering principals such as the design-build-test-learn cycle – offers an approach to transform microbial engineering into an engineering discipline. This thesis describes the development of a synthetic biology toolbox for studying and engineering SL biosynthesis, comprising a SL production module, a detection module, and characterisation of one of the least understood enzymes in the pathway. Saccharomyces cerevisiae was selected as the initial host organism due to its favourable industrial properties, and previous work demonstrating that it is a suitable host for multiple elements in the SL biosynthetic pathway. However, conversion of β-carotene to CL was achieved at very low titres, with CL produced at approximately 1,000,000-fold lower concentration than b-carotene. This was at least in part due to poor conversion of all-trans-β-carotene to 9-cis-β-carotene through DWARF27 (D27), prompting further investigation into this enzyme.Characterization of enzymes increases the reliability of their deployment as a biological part in an engineered system, and provides background information for enzyme engineering. As little is known about the D27 structure-function relationship, the localization and activity of rice (Oryza sativa) D27 (OsD27) were investigated, and efforts were made to elucidate its three-dimensional structure. In a transient Nicotiana benthamiana system, OsD27 was found in stromal and thylakoid membrane-bound forms, demonstrating the sub-organellar localisation of this enzyme for the first time. A maltose binding protein (MBP) fusion of OsD27 had activity in E. coli, and the purified fusion of OsD27 catalysed the reversible isomerisation of β-carotene around the C9-C10 double bond in vitro, with Km = 3.3 ± 1.2 mM for all-trans-β-carotene and Km = 5.4 ± 1.4 mM for 9-cis-β-carotene. Extensive efforts to crystallise OsD27 for structural characterization did not yield results. Purified MBP fusions of OsD27 aggregated into soluble oligomers ranging from 10-150 nm in hydrodynamic radius. The aggregates were not compatible with crystal formation, and could not be completely dissociated using detergents. A non-aggregating D27 homologue from Ziziphus jujuba was…

▼ Although not associated with mortality, symptoms, complications and the relapsing nature of inflammatory bowel disease (IBD) severely impact patient’s quality of life. Current treatments are coupled with side effects and loss of patient response. Damage to the enteric neurons is consistently associated with intestinal inflammation and considered to underlie the generation of symptoms. Therefore, the enteric neurons are a potential target for novel IBD therapies. Mesenchymal stem cells (MSCs) exhibit anti-inflammatory, immunomodulating, and neuroprotective effects and are demonstrated to participate in tissue regeneration and repair in many pathological conditions. Hence, they are a viable option for the treatment of enteric neuropathy associated with IBD. The studies in this thesis aim to investigate the effects of MSC therapy in averting enteric neuropathy in acute and chronic models of IBD. The results of our studies demonstrated that MSC and conditioned medium attenuated inflammation and averted enteric neuropathy and colonic dysmotility in an acute model of IBD. The effects of MSC treatment are dose-dependent and occur as early as 24h post treatment. We characterized changes to colonic innervation, motility, transit time, microbiota and metabolome in the Winnie mouse model of spontaneously occurring chronic colitis. Our results demonstrated that the Winnie mouse is highly representative of human IBD. The mechanisms underlying colonic dysmotility in Winnie mice were due to inhibition of neuromuscular transmission and smooth muscle responses. We found that multiple high dose MSC treatments induce anti-inflammatory and neurotrophic effects in mice with chronic colitis. Single dose and multiple low dose MSC administrations were ineffective in this model. Overall, we have established the capacity of MSC treatments to attenuate inflammation and enteric neuropathy in acute and chronic models of IBD. These findings are both novel and highly relevant for clinical translation and future investigations of MSC therapy for the treatment of IBD.

▼ This thesis is an attempt at investigating the role that Drosophila melanogaster(hereafter referred to as Drosophila) Down syndrome cell adhesion molecule 2(Dscam2) plays in mushroom body (MB) development. Dscam2 is animmunoglobulin superfamily protein that is thought to mediate homophilic interactionsand contribute to synapse and boundary formation in the Drosophila brain. WhetherDscam2 plays similar or distinct roles in other circuits of the fruit fly nervous systemis only beginning to be explored. Dscam2 expression is dynamic within a distinct setof MB neurons during development, and protein is localised specifically to thedendritic compartment of these cells. Removing Dscam2 from single MB neuronsusing mosaic techniques results in an increase in the number of dendritic claws, thestereotypic postsynaptic structures that form connections with boutons from antennallobe projection neurons. These results suggest that, Dscam2 is trafficked to MBdendrites, and through mechanisms that remain to be determined, restricts dendritenumbers of MB neurons.

The Role Of Putative Nox Inhibitors In Homocysteine-Induced Vascular Dysfunction.
Degree: phd, Institute for Health and Sport, 2018, Victoria University

▼ Excess plasma homocysteine (Hcy; hyperhomocysteinemia, HHcy) remains an independent risk factor for cardiovascular disease (CVD) and treatments remain elusive. The source of Hcy, methionine, is an essential amino acid acquired by ingestion of animal foods. Normal methionine metabolism effectively removes Hcy via recycling back into methionine or excretion via the kidney. However, in aberrant methionine metabolism, Hcy accumulates and causes damage to the vascular system by increasing oxidative stress; the exact mechanism of how this occurs is unknown. Importantly, the B vitamins B6, B9 and B12 are essential to proper methionine/Hcy metabolism and are often found in low levels in patients presenting with HHcy; this has provided a potentially viable treatment strategy in the clinical setting. Disappointingly, clinical trials administering B vitamins to reduce HHcy have been unsuccessful in reducing CVD and treatments continue to be sought.
The NADPH oxidase (Nox) family of enzymes are expressed in a broad range of cell types throughout the body and are the primary source of superoxide (Nox1, Nox2) and hydrogen peroxide (Nox4) within the vasculature under both physiological and pathological conditions. Nox1, 2 and 4 are of primary interest in vascular disease, as there is evidence that Hcy can interfere with the proper function of Nox1, 2 and 4 signalling, potentially leading to an over-expression of pro-oxidants. Nox1, 2 and 4 have been implicated in vascular disease (endothelial dysfunction), hypertension, vascular inflammation, stroke, diabetes, and atherosclerosis, and putative inhibitors of these enzymes are now available. Additionally, nitric oxide (NO) is also measured as a marker of proper vascular function; indeed, the current gold standard of assessing NO availability is by indirectly measuring vascular responses to acetylcholine. Accordingly, a loss of NO bioavailability is linked to the development of many of the same vascular pathologies caused by HHcy and also potentially increased Nox1, 2, and 4 activity.
Thus, this thesis examined if current putative Nox inhibitors could prevent vascular dysfunction caused by homocysteine (as indirectly measured by acetylcholine-mediated vasorelaxation). Using New Zealand white rabbits, C57BL/6 mice and a Nox2-/- (C57BL/6 background) mouse models, we observed that pharmacological intervention with single Nox1, 2 and 4 inhibitors reduced the effect of acetylcholine on vasorelaxation. In 1% methionine-fed Nox2-/- mice, we observed an improvement in function. We also assessed combinations of Nox1, 2 and 4 inhibitors and found that, although function was not restored to control levels, it was improved compared with single Nox inhibition. Due to these results, we performed a gp91ds-tat dose response in rabbit aorta. We found that in our models of vascular dysfunction, lower doses of gp91ds-tat significantly improved acetylcholine-mediated vasorelaxation. These results showed for the first time that in both pharmacological and diet-induced HHcy, high dose putative Nox…

▼ HPV oncogenes disable a number of tumour suppressor pathways, including p53 and Rb, contributing to the transformed phenotype. Loss of these critical host cell functions may also provide an opportunity to selectively target the destruction of HPV-transformed cells. We have performed an siRNA screen using the kinome (779 genes) library to identify genes that when depleted are synthetically lethal with HPV transformation. The primary and validations screens have confirmed Aurora A kinase (AURKA) as a potential synthetic lethal target selective for HPV transformed cells. AURKA has been further investigated using the selective small molecule inhibitor MLN8237. We found that MLN8237 was significantly more potent towards the HPV transformed cells. The effect was not a consequence of targeting mitosis as two other mitotic inhibitors, PLK1 inhibitor (BI2536) and taxol, demonstrated no selectivity. Analysis of the nuclear structure and DNA content showed that Aurora A inhibition promoted a high level of polyploidy in non-HPV treated cells whilst this same degree of polyploidy was associate with apoptosis in the HPV-transformed cell lines. Whereas Bcl-2 over expression in HeLa cells had no effect on sensitivity to MLN8237, Mcl-1 overexpressing HeLa cells were less sensitive to the MLN8237 in comparison to the parental cell line, which may suggests the involvement of Noxa or Puma pro-apoptotic proteins in the induction of the apoptosis in the HPV-transformed cells. The transfection of the non-HPV C33A cervical cancer and SCC25 squamous cell carcinoma cell lines with the HPV16 oncogenic E7 increased sensitivity to MLN8237 between 3 >10 fold suggesting that the sensitivity to MLN8237-dependent killing was a direct consequence of HPV E7 expression. Xenograft experiments with cervical cancer cell lines in immunodeficient mice showed MLN8237 inhibited growth of HPV and non-HPV xenografts during treatment with 30mg/kg MLN8237 once a day for 10 consecutive days. However, outgrowth of tumour was noticed from the second day post-treatment in the non-HPV tumour group whereas the HPV-induced tumour group did not show cancer recurrence for 50 days post-treatment. These findings suggest that MLN8237 represent a promising novel therapeutic targeted agent against HPV-transformed cervical cancer.

▼ Liver glycogen, a highly branched glucose polymer, has a critical role in the maintenance of blood glucose homeostasis. Liver glycogen consists of glucose units that are attached to form linear chains via alpha-(1→4) linkages. These chains are connected via alpha-(1→6)-linked branch points to form highly branched glycogen “beta” particles (~20 nm in diameter) that can further join to form much larger “alpha” particles (~100-200 nm). Given the characteristically poor blood-glucose control associated with type 2 diabetes, a link between the structure/function relationships of liver glycogen and type 2 diabetes is probable. It is shown that diabetic (db/db) mice have an impaired ability to synthesize the large composite glycogen alpha particles present in normal, healthy mice and that alpha particles are held together via a bond more acid labile than normal glycosidic linkages, with the most likely bond being proteinaceous. The structure of healthy mouse liver glycogen over the diurnal cycle is characterized using size exclusion chromatography and transmission electron microscopy. Glycogen is observed to be initially formed as smaller beta particles, only being assembled into the larger alpha particles significantly after the time when glycogen content reaches a maximum. This pathway, impaired in diabetic animals, is likely to give optimal blood-glucose control, as explained by the particles’ surface area to volume ratio. Lack of this control may result from, or contribute to, the poor glycaemic regulation associated with diabetes. This discovery suggests novel approaches to diabetes management that promote alpha particle formation. Significant improvements in the extraction and characterization of liver glycogen has also been achieved, paving the way for future experiments exploring glycogen’s role in diabetes. Glycogen can now be effectively and rapidly extracted from formalin-fixed tissues using a novel technique, allowing the analysis of human tissue samples from pathology laboratories that routinely employ this method of fixation. The use of aqueous size exclusion chromatography has been shown to dramatically improve peak resolution when compared to the previously used dimethyl sulfoxide method, achieving separation of alpha-particle and beta-particle peaks. This allows for a more detailed and quantitative analysis and comparison between liver glycogen samples.

The in vivo roles of Sirtuin 1 and 3 in age and obesity-related decline in female fertility.

▼ Sirtuin 1 (Sirt1) and Sirtuin 3 (Sirt3), are members of the sirtuin family of NAD+-dependent deacetylases. Sirt1 exerts its function in the nucleus, whereas Sirt3 exerts its function in mitochondria. Both Sirt1 and Sirt3 are indispensable for mitochondrial function and antioxidant defences in somatic cells. Mitochondria and oxidative stress are pivotal determinants of oocyte developmental competence (also known as quality). Thus far, analyses of Sirt1 and Sirt3 activities in oocytes have been limited to in vitro knockdown and chemical inhibitor approaches. Significantly, the in vivo roles of Sirt1 and Sirt3 for female fertility have not been formally tested. Since results with whole-animal knockouts would be confounded by the indispensable requirement for Sirt1 in somatic cells, I used the Zp3-Cre-LoxP system to specifically delete Sirt1’s catalytic domain in vivo in growing oocytes (OoSirt1∆Ex4/∆Ex4). To investigate the role of Sirt3 for female fertility, I employed a whole-animal Sirt3-knockout (Sirt3-/-) mouse model.I evaluated female reproductive capacity by quantifying ovarian follicles (ovarian sections); in vitro meiotic maturation, spindle assembly and chromosome segregation (time-lapse confocal microscopy); in vitro preimplantation embryo development; expression of SIRT1 and SIRT3 transcription targets (qRT-PCR); oocyte oxidative stress and mitochondrial content (confocal imaging), and; reproductive capacity (mating trials).Surprisingly, I found that all these parameters were indistinguishable in young (2-month-old) OoSirt1∆Ex4/∆Ex4 and Sirt3-/- females compared to corresponding wild-type females. I reasoned that the roles of Sirt1 deacetylase activity in oocytes (oocyte-Sirt1) and Sirt3 in mitochondrial function and antioxidant defences might become apparent under stressed conditions. Therefore, I undertook further analyses under two in vivo stressed states: natural ageing (10-12-months) and obesity induced by high-fat diet (HFD).Very interestingly, my analysis revealed an age-accelerated decline in reproductive performance in OoSirt1∆Ex4/∆Ex4 females, which was due to a decline in oocyte quality. Interestingly, compromised oocyte quality does not impact in vivo oocyte maturation or fertilisation but leads to increased oxidative stress in preimplantation embryos inhibiting cleavage divisions. Remarkably, HFD-induced obese OoSirt1∆Ex4/∆Ex4 females showed no defects in any of the above parameters (including litter sizes) when compared to wild-type females. Also, Sirt3-/- females exhibit no defects in oocyte quality and reproductive performance even following HFD-induced obesity and natural ageing.In my PhD project, I thoroughly interrogate the in vivo roles of oocyte-Sirt1 and Sirt3 for female fertility for the first time. My data suggest that defects in aged females lacking oocyte-Sirt1 arise due to concurrent age-related changes such as reduced NAD+ and sirtuin expression levels, which may compromise compensatory mechanisms that can cover for Sirt1 loss in younger oocytes. In contrast to evidence that…

▼ Mosquitoes are considered as the most dangerous animals on earth if all the diseases they transmit are taken into account. Different species of mosquitoes transmit different pathogens ranging from viruses to parasites, but the transmission of these microorganisms comes down to a specific aspect of those mosquitoes’ biology, blood feeding. One of the most important vectors is Aedes aegypti responsible for transmission of viral diseases such as Dengue, Zika and Chikungunya among others. From those, dengue virus (DENV) has the highest prevalence, infecting about 390 million people a year in over 100 countries. No efficient vaccine or treatment exists at the moment making vector control the main way of prevention. Despite the existence of different methods to control the vector, epidemics continue to arise. This makes the study of A. aegypti biology and its interaction with different viruses important in the fight against these diseases.When DENV infects a cell, a reorganization of the membranes of the endoplasmic reticulum forms the replication complex, a place where viral translation and replication occurs. In mammals, the formation of the replication complex is preceded by the binding of viral non-structural proteins to STT3A, a member of the oligosaccharyl transferase complex (OST). Knockout of STT3A decreases viral titres in orders of magnitude in mammalian cells. We found that after silencing STT3A or other proteins of the OST complex, STT3B and MAGT1, viral titres and genomic copies of DENV were not altered in A. aegypti cells. The reason for this is not known but this points to an important difference in the formation of replication complexes in mosquito and mammalian cells.One of the most important biological processes for mosquitoes is blood feeding. This process is key for two main reasons: (1) this is the moment when a mosquito gets infected with a pathogen. In the context of A. aegypti-DENV interaction, the infection, replication and virion production of DENV has been studied extensively in mammalian cell lines, but fundamental aspects of the replication of the virus in mosquitoes are still less known. (2) Blood feeding is the way females acquire nutrients for egg laying, making it a vital step in their life cycle. Blood is a complex mixture of water, cells, proteins, lipids, and other elements that have regulatory functions in mosquito physiology. While the effect of most of these components on mosquitoes have been studied in detail, the potential regulatory role of host blood microRNAs (miRNAs) on mosquitoes has not been investigated.miRNAs are RNA molecules of approximately 22 nucleotides in length that regulate gene expression post-transcriptionally. miRNAs have been shown to modify many biological processes in a wide range of organisms including A. aegypti. We detected human miRNAs (hsa-miRNAs) in the fat body of A. aegypti mosquitoes as early as 6 hours after blood feeding lasting up to 24 hours after blood feeding. We used the two most abundant miRNAs found in the fat body to determine if they have…

▼ Renal cell carcinomas (RCC) are highly metastatic and therapy-resistant. Several novel tyrosine kinase inhibitors (TKI) targeting angiogenesis have been introduced into clinical practice for RCC, the most common being sunitinib. However, use of sunitinib is limited by development of therapy resistance in RCC. Comprehensive characterisation of morphological, functional and molecular changes in sunitinib-resistant RCC cells is lacking. Understanding the mechanisms of resistance to sunitinib therapy, and developing measures to overcome resistance, may help improve patient care.The overall hypotheses of this project were: 1) that RCC models that demonstrate resistance to current RCC therapies can be utilised to investigate and define molecular pathways of resistance; and 2) that these same models can be used to test novel therapies. Specifically, the project aimed: 1) to develop and characterise RCC cell lines that are resistant to sunitinib; 2) to explore the mechanisms of resistance in the RCC cell lines with emphasis on angiogenic and apoptotic pathways; 3) to overcome sunitinib-resistance with appropriate agents using in vitro methodologies; and 4) to validate in vitro findings in a murine xenograft model of RCC.A literature review is provided in Chapter 1, and general Materials and Methods are described in Chapter 2. Chapters 3 describes development of sunitinib resistance in four human RCC cell lines: 786-0, Caki-1, Caki-2, and SN12K1 and characterise the differences in cell and molecular biology from parental RCC cell lines. The RCC cell lines were made resistant to continuous, chronic exposure to 10 μM sunitinib. Cell growth/proliferation (MTT assay), morphology and apoptosis (phase-contrast microscopy and hematoxylin-eosin staining), transmigration (migration chamber), and gene expression (qRT-PCR) for interleukin-6 and -8 (IL-6, IL-8), vascular endothelial growth factor (VEGF), Bcl2 and Bax were studied. Resistant cells were stable in 10 μM sunitinib, maintained viability in 20 μM sunitinib, and have now been in culture for over two years. Resistant cells proliferated more slowly, but were significantly hypertrophic compared with parental cells. The transmigration assay showed no difference between resistant cells and their respective parental cells. One of the most striking differences between resistant and parental RCC was that IL-6 (in all RCC) and IL-8 (in most RCC) significantly increased in resistant cells, with an associated increase in VEGF. An anti-apoptotic mechanism was also demonstrated in therapy-resistant RCC. Increased IL-6 may contribute to resistance of RCC through downstream upregulation VEGF.Thus, IL-6 increase was considered worthy of further investigation as a potential therapeutic target for therapy-resistant RCC. In Chapter 4, resistant cells were grown with and without Tocilizumab (50 μg/mL), a monoclonal antibody that blocks the IL-6 receptor (IL-6R) protein. Cell growth/proliferation, cell morphology and apoptosis, gene expression (qRT-PCR) and protein levels (ELISA) for IL-6, VEGF,…

▼ The investigations described in this thesis were prompted by an overall interest in the phenomenon of Troponin C (TnC) polymorphism in mammalian skeletal muscle. Gaining
insights into this area of inquiry has been limited, in large part due to methodological problems associated with the identification of rat (a commonly used animal model for
studying mammalian skeletal muscle) TnC isoforms on SDS gels. Therefore, a method was devised for unambiguous identification of TnC isoforms in rat single muscle fibres.
This method, validated using rat skeletal muscle TnC isoforms purified for the first time as part of this study, was used in conjunction with myosin heavy chain (MHC) isoform based fibre-typing and Sr2+ -activation measurements to explore the relationship between MHC and TnC isoform composition in mammalian skeletal muscle at the single fibre level, and to revisit the controversial issue of the relationship between TnC isoform composition and fibre-type differences with respect to Sr2+ -activation characteristics.

▼ Protease-activated receptors (PARs) are class A G protein-coupled receptors (GPCRs) with 4 subtypes (PAR 1 – 4) and with a unique mode of action. PARs are cleaved by extracellular proteases at the N-terminus, creating a new tethered ligand that activates the receptor and transduces biological signals into the
cell. PARs have been implicated in various productive and pathological signals, including those related to thrombosis, inflammation, reperfusion injury, and cancer
cell metastasis. Despite the fact that PARs are attractive as drug targets, their intramolecular mode of activation makes it challenging to modulate them with drugs in a selective manner, and only one PAR-targeting therapy, the PAR1 antagonist and antiplatelet drug vorapaxar, is currently approved by the FDA. Previously in the Dockendorff lab, compounds with a 1,3-diaminobenzene scaffold, called parmodulins, were identified as biased ligands of PAR1 that selectively inhibit Gαq-mediated signaling of PAR1 without significantly inhibiting Gα12/13-mediated signaling leading to platelet shape change. More recently, cytoprotective and anti-inflammatory effects of parmodulins in endothelial cells were identified that could be fruitful for the treatment of sepsis and myocardial infarction. We developed a Gαq-mediated intracellular Ca2+ mobilization (iCa2+) assay in endothelial cells to perform medium-throughput screening and characterization of parmodulins, and we demonstrated that they are reversible, negative allosteric modulators of PAR1, unlike ligands such as vorapaxar. We also extended structure-activity relationship (SAR) studies of parmodulins to identify analogues with potentially improved properties using medicinal chemistry, and these parmodulins are promising leads for safer antithrombotic and sepsis drugs. Additionally, we commenced investigations into the role of heteromeric PAR complexes in proliferative disorders such as restenosis and cancer
cell metastasis. We synthesized a novel class of bivalent ligands targeting putative PAR1/2 heteromers and characterized them using our iCa2+ assay with endothelial cells (EA.hy926) and the breast cancer
cell line MDA-MB-231. Such bivalent PAR ligands hold promise for the selective treatment of cancer and other proliferative disorders.

▼ The myosin myo1c dynamically localizes to cellular membranes through high affinity phosphoinositide binding and links them to the actin cytoskeleton. Determining the kinetics of membrane attachment will provide insight into the relationship between membrane-attachment and actin-attachment lifetimes, and will also provide details about the regulation of membrane attachment. Stopped-flow spectroscopy was used to measure the binding and dissociation of a recombinant myo1c construct containing the tail and regulatory domains (myo1cIQ-tail) to and from 100 nm diameter large unilamellar vesicles (LUVs). The apparent second-order rate constant for association of myo1cIQ-tail with LUVs containing 2% phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) was approximately diffusion-limited. Myo1cIQ-tail dissociated from PtdIns(4,5)P2 at a slower rate (2.0 s-1) than the pleckstrin homology domain of phospholipase C-δ (PLCδ-PH) (13 s-1). The presence of additional anionic phospholipid reduced the myo1cIQ-tail dissociation rate constant > 50-fold, but marginally changed the dissociation rate of PLCδ-PH, suggesting that additional electrostatic interactions in myo1cIQ-tail help to stabilize binding. Remarkably, high concentrations of soluble inositol phosphates induce dissociation of myo1cIQ-tail from LUVs, suggesting that phosphoinositides are able to bind and dissociate from myo1cIQ-tail as it remains bound to the membrane.
In adipocytes, vesicles containing glucose transporter-4 (GLUT4) redistribute from intracellular stores to the cell periphery in response to insulin. Vesicles then fuse with the plasma membrane, facilitating glucose transport into the cell. To gain insight into the molecular role of microtubules, we examined the spatial organization and dynamics of microtubules in relation to GLUT4 vesicle trafficking in living 3T3-L1 adipocytes using total internal reflection fluorescence (TIRF) microscopy. Insulin stimulated an increase in microtubule density and curvature within the TIRF-illuminated region of the cell. The time course of the density increase precedes that of the increase in intensity of HA-GLUT4-eGFP in this same region. Microtubule disruption delayed and modestly reduced the accumulation of GLUT4 at the plasma membrane. Interestingly, fusion of GLUT4-containing vesicles with the plasma membrane preferentially occur near microtubules, and long-distance vesicle movement along microtubules visible at the cell surface prior to fusion does not appear to account for this proximity. We conclude that microtubules may be important in providing spatial information for fusion events.

▼ Affordable production of pharmaceuticals with high potency and low side effects is a major challenge of the 21st century. Peptides are an emerging class of therapeutics that have the potential to marry the specificity and efficacy of protein drugs with the stability and membrane permeability of small molecule drugs. Although many peptides are amenable to chemical synthesis, their cost of production is high, as is the generation of waste products. Peptide production in plants has the potential to be a scalable, cost effective, and a less environmentally taxing alternative. Cyclotides, first discovered in Oldenlandia affinis, are a unique class of backbone cyclic peptides containing three stabilising disulfide bridges that form a knot-like structure. Their stability, and for some variants, the ability to traverse cellular membranes make them ideal candidates for pharmaceutical and agricultural applications. Even though highly constrained sterically, cyclotides are amenable to engineering by replacing native sequences with bioactive epitopes. In this thesis, cyclotide production strategies in plant cell suspensions are examined with a special focus placed on O. affinis as an archetypical cyclotide producer. Additional species investigated are Clitoria ternatea, Hybanthus enneaspermus, Nicotiana benthamiana, and Petunia hybrida. Insights into how cyclotides and their biosynthetic processing machinery are regulated in suspension plant cells are reported and provide first steps towards an affordable and environmentally friendly peptide production system in plants.Chapter 1 introduces the relevant scientific knowledge. The journey starts with a description of proteins and peptides, emphasising cyclotides and their synthesis. Then, current production strategies are compared with plant-based systems. The advantages and disadvantages of bioreactor setups suitable for medium to large scale production of cyclotides in plant cell suspensions are subsequently outlined. Finally, the importance of downstream processing is discussed. At the end of Chapter 1, the scope of this thesis is outlined to give an overview of the scientific questions addressed.Chapter 2 lays the experimental groundwork upon which the rest of this thesis is built. Protocols to establish C. ternatea, H. enneaspermus, N. benthamiana, O. affinis, and P. hybrida suspension cultures were developed and their cyclotide accumulation profiles presented. Cycloviolacin O2, a cyclotide previously reported only in the Violaceae, was discovered in O. affinis suspension cells and corroborated in the O. affinis leaf transcriptome. Two new cyclotides, kalata B22 and kalata B23, were characterized from O. affinis suspensions and were shown to have high sequence similarity to a group of cyclotides found in suspension cells of multiple plant families. Additionally, a strong time dependent effect was observed for cyclotide production in O. affinis suspension cells and was connected to reduced cyclotide mRNA expression. Cyclotide production was tissue specific in all tested…

▼ Cardiac CSQ (CSQ2) is a multifaceted protein, capable of binding significant quantities of Ca2+ and altering ryanodine receptor activity at the junctional sarcoplasmic reticulum (SR). Little is known about the trafficking of CSQ2 from its unknown site of biosynthesis, which appears to be of importance as its structure changes in a trafficking-dependent manner in various types of heart failure. Through the use of multiple antibodies specific to classic rough ER markers, and with the creation of CSQ-DsRed tetramer fusion protein, we were able to establish a juxtanuclear localization of rough ER in cardiomyocytes. Using fluorescence confocal microscopy, the translocon complex proteins TRAP-α and TRAM, along with the ribosomal protein S6, were all visualized and found to encapsulate both myonuclei. Additionally, time course studies of CSQ-DsRed, in conjunction with anti-DsRed immunostaining, highlighted a perinuclear rough ER site of biosynthesis for CSQ2. The fusion protein exhibited a tetramerization-dependent trafficking predicted to be very similar to CSQ2 polymerization-dependent trafficking with high and low secretory compartment Ca2+ concentrations leading to polymerization and monomerization, respectively.
Cardiac-specific C-terminal phosphorylation of CSQ2 serines was shown to effect CSQ2 trafficking according to mass spectrometric analysis of the protein's N-linked glycan. A Ser 378,382,386 Ala mutation (CSQ-nonPP) of these sites inhibited CSQ2 phosphorylation and led to an increased trafficking out of the ER as indicated by the increased mannose trimming of CSQ2 glycan. This effect was reversed with the phosphomimetic mutant Ser 378,382,386 Glu (CSQ-mimPP) which had glycoforms with mannose trimming nearly identical to that of CSQ-WT.
Pharmacological and molecular inhibition were used to establish the identity of CSQ2 kinase as protein kinase CK2. In vitro, inhibition of CSQ2 phosphorylation using cardiomyocyte and nonmuscle
cell CSQ2 kinase sources was successfully carried out with three specific inhibitors of CK2: TBB, DMAT and TBCA. TBCA produced identical inhibition curves for both cellular kinase sources and commercial CK2α′ kinase, with increasing concentrations of drug. SiRNA knockdown of both CK2α and CK2α′ catalytic subunits in nonmuscle cells reduced CSQ2 kinase activity by nearly 2-fold according to similar in vitro CSQ2 phosphorylation assays.
Additionally, both ATP-binding site competitive inhibition and CK2 RNAi protein inhibition were used successfully in situ to suppress endogenous CSQ2 phosphorylation. TBCA used at 100 µM with CSQ-WT overexpressing cardiomyocytes and COS nonmuscle cells in culture led to an 82 and 66% decrease in CSQ2 phosphate incorporation, respectively, compared to control. Similarly, simultaneous knockdown of both CK2α and CK2α′ catalytic subunits in COS cells overexpressing adenoviral CSQ-WT, caused a near 2-fold decrease in CSQ2…

▼ The nuclear factor erythroid 2 (NF-E2)-related factor 2 (NRF2) transcription factor has been widely studied for its role as the master regulator of the response to oxidative stress. NRF2 has many mechanisms for protection including upregulation of antioxidant genes, metabolism genes, and proteolysis genes. Furthermore, it was found that a deeply conserved set of NRF2 target genes encode for proteins loaded into exosomes [1]. Exosomes are extracellular microvesicles that are secreted by cells in response to a variety of stimuli, including many stressors. Exosomes serve as a transport mechanism for proteins, RNA, DNA, and other molecules. Therefore, we hypothesized that exosome loading and release is a mechanism used by NRF2 to protect neighboring cells from stress in a non-autonomous manner. In an effort to validate that NRF2 regulates exosomes, I explored the following: (1) exosome release before and after NRF2 activation, (2) the RNA and protein content of NRF2-induced exosomes, and (3) the cytoprotective potential of NRF2-induced exosomes. Overall, based on these studies, we concluded that NRF2 activation induces exosome release, and exosomes are generally enriched for cytoprotective protein SQSTM1. However, although NRF2-induced exosomes were cytoprotective in some assays, this response was not robust enough for me to conclude that NRF2-induced exosomes can protect naïve cells from oxidative stress. Thus, exosomes provide a potential mechanism for NRF2 to provide nearby cells with resources to combat oxidative stress, but further research is necessary to determine whether this mechanism is used in vivo.

▼ Human acidic Fibroblast Growth Factor 1 (FGF-1), a member of the FGF superfamily, is a potent mitogen and heparin-binding protein involved in a broad spectrum of biological processes, including angiogenesis,
cell proliferation, and wound healing. Design of hFGF-1 with an increased thermal stability and an enhanced
cell proliferation activity is highly desired for wound healing applications. Herein, we have designed the variant of FGF-1 by substituting two important amino residues in the heparin-binding pocket. The variant was overexpressed in Escherichia coli and was successfully purified to homogeneity using an affinity chromatographic procedure. Far-UV circular dichroism spectroscopic analysis showed that the backbone conformation of the hFGF-1 did not alter due to the introduction of mutations in the heparin-binding pocket. The designed hFGF-1 variant exhibited an increased resistance to limited trypsin digestion. Isothermal titration calorimetry study confirmed that approximately 20-fold decrease in heparin binding affinity (Kd ~90µM) was observed in case of the double mutant compared to that of the wild-type FGF1 (~5µM). Incorporation of positively charged Lys135 adjacent to the negatively charged E136 might have reduced the repulsive effect to heparin. 8-Anilino naphthalene 1-sulfonate (ANS) binding assay revealed that the introduced mutations cause a subtle change in the solvent-accessible non-polar surface of the protein. These results were in concordant with other biophysical data obtained from limited trypsin digestion, 1H 15N HSQC analysis. In addition, no significant change in bioactivity was observed between the mutant and the wild-type FGF1 proteins. This confirms that introduction of positive charge adjacent to E136 nullified the effects of this unique mutation.

▼ The Maillard Reaction (MR) is a non-enzymatic chemical reaction which results in linkage between the amino group of amino acids and the carbonyl group of reduced sugars. This reaction generates Maillard reaction products (MRPs) which are not present naturally in foods, and are responsible for a range of colors, odors, flavors, and other sensory properties. Conflicting reports of MRPs impacts on human health are probably due to the fact that bioconversion of these digestible molecules by the gut microbiota has been marginally taken into account. This study aimed to determine the effects of different MRPs on rodent’s gut microbiota through16S rRNA amplicon sequencing over three different studies. Study 1 focused on the impact of NƐCarboxymethyllysine (CML) on the composition of mice gut microbiota and potential association with severity of experimental colitis. Study 2 focused on the impact of bread melanoidins on the composition of healthy and experimental colitis mice gut microbiota. Study 3 focused on the impact of consumption of increasing amounts of malt melanoidins on mice gut microbiota. It was found that CML induced limited changes in gut microbiota profiles of healthy mice, but was found to significantly relieve the bacterial dysbiosis imparted by one (but not the other) inflammation-inducing chemical, especially the Proteobacteria bloom. Bread crust model (high in melanoidins) showed significant decreases of Bacteroides spp. and Enterobacteriaceae, while it increased Faecalibacterium spp. Also, bread crust model limited to increase Enterobacteriaceae in colitis model. High amounts of malts rich melanoidins rapidly and persistently led to significantly different gut microbiota profiles. There was a trend for decrease of Lactobacillus and Ruminococcus and increase of Akkermansia and Bifidobacterium with higher amounts of dietary melanoidins. We concluded that CML and melanoidins are not detrimental in terms of their impact on the gut microbiota, and that they may even have prebiotic properties.

▼ In the budding yeast,
Saccharomyces Cerevisiae, dynein, a minus-end directed motor, is involved in nuclear migration and proper orientation of the mitotic spindle during mitosis. Our lab has developed a model that involves the loading of cytoplasmic dynein onto the plus-end of astral microtubules through interactions with Pac1/LIS1 and Bik1/CLIP-170. Dynein is then delivered to the
cell cortex and anchored through a cortical receptor protein, Num1. Num1 is a 313KDa protein that localizes to the
cell cortex and is an essential component of dynein mediated nuclear migration.
Using quantitative fluorescence techniques I was able to create a molecular inventory of various dynein pathway components. Our results revealed Dyn1, dynein heavy chain, and Pac1/LIS1 associate at the plus end in a 1:1 ratio. Additionally we found that dynein and dynactin associate in a 3:1 ratio at the plus ends and a 2:1 ratio at the cortex. Interestingly, we found that over expression of Pac1/LIS1 augments cortical dynein activity while maintaining the dynein to dynactin ratio and this activity is separate from loss of She1, a negative regulator of dynein-dynactin interaction, which results in a 1:1 ratio of dynein-dynactin at the plus-ends, as well as, the cortex. Our results uncover molecular ratios that enable us to create more defined and detailed model of the dynein pathway.
To elucidate how Num1 attaches dynein to the cortex we created truncations of the Num1 protein. We were able to determine that two coiled-coil (CC) domains in the N-terminus of Num1 are responsible for bright foci formation on the cortex. Cells without these bright foci exhibit a binucleate phenotype similar to that of
dyn1∆ implicating that these bright foci are required for the proper function of Num1 in the dynein pathway.
To test the hypothesis that the CC is capable of mediated bright patch assembly through self-association I purified a recombinant CC domain and performed gel filtration analysis, as well as, equilibrium sedimentation. I was able to determine that the CC domain exists as a dimer in solution. However, the mechanism of CC self-assembly may involve a requisite of targeting the CC to the cortex first.

▼ Small GTPases of the Rab family have wide ranging and essential roles in recruiting effectors to mediate membrane trafficking and receptor signalling events in mammalian cells. Nucleotide loading and activation/deactivation of the Rabs themselves are regulated by guanine nucleotide exchange factors (GEFs), GTPase activating proteins (GAPs) and other accessory proteins. While Rabs have important roles in innate immune cells, for host-pathogen interactions, receptor signalling and membrane trafficking, in many cases their GEFs and other accessory proteins have not been elucidated.Pathogen-activated, Toll-like receptors (TLRs) initiate and modulate transcription of inflammatory cytokines and other innate immune responses which are important for immune defence but can also contribute to chronic disease. Macrophages are key cells of the innate immune system and previous work from our laboratory established a role for promiscuous Rab family member, Rab8a, in TLR signalling. Rab8a is activated in TLR pathways to recruit phosphoinositide 3-kinase gamma (PI3Kg) as an effector which upregulates TLR-induced Akt/mTOR signalling to drive a biased program of anti-inflammatory cytokines. TLR-associated PI3Kg has now emerged as a key mediator of macrophage programming (or polarisation) in inflammation and cancer and its cognate GTPase, Rab8a, has a prominent role in immunity and disease. Rab8a is itself recruited to macrophage ruffles and macropinosomes through its association with the TLR crosstalk-activated endocytic receptor LRP1. However, it is not yet known how Rab8a is activated in TLR pathways. This project set out to identify the essential Rab8a GEF(s) needed to activate Rab8a as part of the LRP1 complex.Two well-known Rab8 GEFs, GRAB and Rabin8, which previously were uncharacterised in macrophages, were investigated in this project. GRAB was identified as part of the low density lipoprotein receptor-related protein 1 (LRP1) complex in pull-downs analysed by mass spectrometry. Co-immunoprecipitation and fluorescence microscopy showed that both GRAB and the structurally similar GEF, Rabin8, undergo LPS-inducible binding to Rab8a and are localised at sites of Rab8a enrichment. To carry out functional studies, stable knockouts (KOs) of Rabin8, GRAB, as well as a double KO were produced via CRISPR-Cas9 gene editing in macrophage cell lines. Nucleotide activation assays were developed for this project and live-cell imaging with KO cell lines showed that both GEFs contribute additively to TLR4-induced Rab8a GTP-loading, but they are not needed for Rab8a membrane recruitment. Analysis of TLR signalling after double KO of both GEFs suggested redundant roles for Rabin8 and GRAB in activating Rab8a for PI3Kg-dependent Akt/mTOR signalling. Live cell imaging utilising a fluorescent Akt1 reporter confirmed that LPS/TLR-induced Akt signalling is generated on macropinosomes and requires GRAB and Rabin8 GEF function.Next, to investigate possible regulators of the Rab8 GEFs, pull-downs and mass spectrometry were performed and identified a…

▼ The main objective of this thesis is to enhance topical delivery targeting early stage cutaneous melanoma aiming to increase therapeutic effects using optimal formulations. To achieve this primary aims, various approaches were applied such as (i) formulation behaviour studies using in vitro kinetic analysis, (ii) pre-formulation toxicity studies to select the safe raw ingredients, and (iii) Self-Emulsifying Microemulsion (SEME) systems was to enhance the drug delivery while reducing the toxicity.Early research was initiated by screening some small molecules with potential to be used as anti-melanoma agents, incorporated in topical formulations. In vitro cell culture of human melanoma and non-melanoma skin cells was employed as the biological model. Rose Bengal and coumarin were selected as active agents and classified as compounds with high and low potency based on the IC50 ranking. Different formulation approaches were considered for each compound according to their potency and physicochemical properties to enhance their bioavailability, anti-proliferative activity and minimize skin irritancy.Chapter 3 focuses on the relationship between the physicochemical properties of coumarin and its skin permeation from simple ternary solutions. Understanding of thermodynamic activity/solubility parameters of coumarin in delivery systems is used as an approach to enhance solubility and penetration of the drug and thus improving the anti-melanoma effect at the target site. The aim is to explore the impact of various solutions containing three universal solvents on skin permeation of drug and the performance of the final product through assessing the relationships between drug-vehicle, drug-skin, or drug-vehicle-skin interaction. Comparison of in vitro penetration fluxes (Jmax30%) and solubility of the drug in vehicles (Sv) was undertaken. Formulation 5 containing 70% Eth: 10% PG: 20% water showed the highest delivery for coumarin across the skin with the maximum flux of 1281.4 (µg/cm2/h).The relationship between solubility of coumarin in vehicles with Jmax showed that coumarin penetration through the skin is mainly depends on the solubility in the vehicles. Mechanism of Eth and PG to enhance permeation was through increasing the solubility of coumarin in the vehicle and in the stratum corneum, leading to improved partitioning. Enhancements in stratum corneum solubility were found to be related to uptake of solvents. These results showed that it is possible to enhance targeted efficacy of coumarin in skin by enhancing the solubility of the drug in formulation. HSP approach showed to be valuable in predicting the parameters that influence permeation of coumarin in various vehicles.In Chapter 4, in vitro toxicology of all formulation ingredients was evaluated on various skin cell lines to understand the toxic effects of the excipients for clinical applications. The toxicity level was measured by means of cell viability (IC50) using two distinct endpoint assays: MTT and Crystal violet. The MTT assay measures the reduction of MTT…

▼ Next generation sequencing has allowed researchers to characterise the somatic landscape of cancer genomes, which has led to the discovery of biomarkers that may be predictive and prognostic to targeted therapies. However, the efficacy of current targeted therapies has failed to raise the overall survival curve in many tumour types. Immunotherapy has shown a promising benefit in treating many tumours and demonstrated remarkable responses even at recurrent, relapse and metastasis stage. Tumour mutation burden (TMB) can stratify some responders and non-responders to Immunotherapies, but it is not perfect. Tumour whole genome sequencing (WGS) and RNA sequencing play a major role in deciphering tumour intrinsic-extrinsic factors and may improve prediction responses to immune checkpoint blockade therapies. This dissertation will explore computational tools that can be applied to understand complex tumour-immune milieu and that may predict a response to immunotherapy.Chapter 2 includes a comprehensive benchmarking analysis of bioinformatics tools to identify cancer-immunity interactions. In addition, tools to predict responses for immune checkpoint blockade therapies were evaluated on publicly available immunotherapy treated clinical datasets. Using this information an immunogenomics pipeline was developed with the bioinformatic tools that showed the best concordance with gold-standard in-vitro techniques. This pipeline was applied in subsequent chapters to predict immunotherapy responses and to identify various tumour immune escape mechanisms in tumour types that have a poor survival.In Chapter 3, I used the immunogenomics pipeline to analyse whole genome sequencing and RNA sequencing of malignant pleural mesothelioma (MPM). MPM is a rare, aggressive cancer associated with asbestos exposure and has very limited treatment options. Heterogeneity was observed in tumour intrinsic and extrinsic factors within MPM patient samples, including clonal selection of neoantigen presentation, altered gene expression profiles in neoantigen trafficking components and enriched immune cells within the tumour microenvironment. This profiling may help in to increase overall survival in mesothelioma by indicating patients who are more likely to be responsive to emerging immunotherapies and importantly providing mechanisms for why other patients may not respond.In chapter 4, I assessed various immune escape mechanisms of microsatellite stable (MSS) primary colorectal and matched liver metastasis tumours. MSS stable tumours are generally thought to be immunogenic “cold” tumours and remain as a major research challenge as they exist in an immune suppressed tumour microenvironment with low TMB. Through matched primary and metastasis WGS and RNAseq analysis I identified loss of heterozygosity of the HLA alleles, consistent neoantigen profiles, heterogeneity in T-cell repertoire expansion and diversity and other tumour microenvironment components that facilitate immune escape mechanisms in “cold” tumours. These findings highlight the mechanisms…

▼ This thesis describes the application of a non-genetic engineering approach, adaptive evolution, to generate variants of Saccharomyces cerevisiae that produce reduced levels of ethanol relative to the strains they were derived from. Sub-lethal concentrations of sulfite, which sequesters acetaldehyde, thereby limiting ethanol production, was used as a selection pressure. However, removal of acetaldehyde not only limits ethanol production,
it also compromises redox balance by preventing the fermentative oxidation of NADH.
To compensate for this, the cell regenerates NAD by producing increased amounts of glycerol; glycerol production is an NADH-driven reductive process. It was demonstrated in this thesis that culturing yeast in presence of sulfite for a number of generation, results
in the generation of genetically stable variants with increased glycerol and reduced ethanol production.

▼ The vast variety of normal pigmentation variation is a huge genetic puzzle and hair colour is one part of this puzzle. It is hypothesised that there are genetic variants
specifically associated with an objectively defined Blonde phenotype. The first objective of this study was to examine the natural, adult hair colour variation among a population of European ancestry and to evaluate methods for both the measurement and classification of hair colours. The second objective was to characterise the microscopic and chemical features of hair colour in this sample and to determine how they relate to the macroscopic colour. The final objective was to compare genetic results with objectively measured and defined hair colour phenotypes in the search for genetic
associations with "blonde‟ hair colour. Having this information will assist in developing forensic predictive tests for physical features.

▼ Currently DNA profiling methods only compare a suspect’s DNA with DNA left at the crime scene. When there is no suspect, it would be useful for the police to be able to predict what the person of interest looks like by analysing the DNA left behind in a crime scene. Determination of the age of the suspect is an important factor in creating an “identikit” (set of drawings of different features that can be put together to form the face of a person). This study investigated if one could use a correlation between telomere length and age, to predict the age of an individual from their DNA. Telomere length, in buccal cells, of 167 individuals aged between 1 and 96 years old was measured using quantitative real time PCR.
The causes for the presence of large variation in telomere lengths in the population were further investigated. The age prediction accuracies were low even after dividing samples into non-related Europeans, males and females (5%, 9% and 1% respectively). Mean telomere lengths of eight age groups representing each decade of life showed a non-linear decrease in telomere length with age. There were variations in telomere lengths even among similarly aged individuals aged 26 years old (n = 10) and age 54 years old (n = 9). One of the factors that causes large inter individual variation could be the inheritance of telomere length. If there is a strong paternal or maternal influence, this could be incorporated into the age prediction formula. Parents’ telomere lengths were compared with children’s telomere lengths.

▼ Non-pathogenic corynebacteria including Corynebacterium glutamicum, Brevibacterium flavum, and B. lactofermentum have been used traditionally for industrial production of amino acids. Recently, these strains have been also studied using molecular biology or recombinant DNA approaches. However, a major early limitation in the application of this technology was poor transformation efficiency due to the presence of barriers which prevented entry or survival of incoming DNA. These barriers are both physical (cell surface structures) and enzymatic (restriction and modification) barriers. The research described in this thesis involved investigating the nature of both the physical and enzymatic barriers, includings: (i) determining the effect of the presence of glycine and/or isonicotinic acid hydrazide (INH) and resulting lipid profiles (mycotic acids and fatty acids) of several strains of corynebacteria. (ii) examining the enzymatic barriers to transformation of these corynebacteria with specific reference to methyltransferase (MTase) activity and the sites of methylation.
