Defining human immune responses to a healthy gut microbiome
Many human diseases are thought to involve interactions between the gut microbiome and the immune system which shape the nature and function of immunity. These interactions between host and environment are thought to be critical regulators of health and disease.In autoimmune diseases many studies have associated presence or absence of particular microbial species with diseases and some studies have shown influence of disease-related genetics on the composition of the gut microbiome. However, no studies to date have formally addressed the …

Using a natural β-carboline dimer compound to target metabolic vulnerabilities linked to glycolysis in prostate cancer
Prostate cancer is an androgen dependent cancer and treatments are aimed at preventing activation of the androgen receptor. Part of the development of resistance to therapies involves prostate cancers reprogramming their metabolism to overcome metabolic stress induced by these therapies and support growth and survival. This reprogramming involves increases in the rate of glycolysis and intermediate pathways branching from glycolysis. Previously in our laboratory, the natural compound, beta-carboline dimer, BD, was identified to have potent effects on cell viability, cell …

Understanding the genetics of melanoma susceptibility: many roads lead to DNA repair
Repair of the damage caused by mutagens such as UV and reactive oxygen species is vital to prevent cancer and premature aging and accordingly cells have developed a suite of intricate and specific DNA repair pathways. Loss or abnormal function of components of these pathways lead to cancer pre-disposition syndromes for example breast cancer in individuals carrying mutations in the BRCA1 or BRCA2 genes. Understanding the complexities of these DNA repair pathways is vital to efforts aimed at preventing or …

Characterising drivers of melanoma cell heterogeneity
Tumour cell heterogeneity is linked to tumour progression through the generation of divergent cellular behaviours such as proliferation, survival, invasion and therapy resistance. Crucially, conventional and targeted therapies generally only target highly proliferative cells in tumours leading to initial tumour regression, however alternative sub-populations underpin the return of treatment refractory disease and facilitate metastatic spread. Our laboratory is focused on understanding the regulatory drivers of cellular plasticity in melanoma to better understand progression and metastatic spread of this disease and …

Dissecting the molecular and cellular basis of melanoma susceptibility
Several factors strongly influence an individual’s chance of developing melanoma. Paramount amongst these are the number of moles (nevi) present on the skin, cumulative levels of UV exposure and skin pigmentation phenotype. Numerous Genome Wide Association Studies (GWAS) we have identified gene variants at a number of loci that are strongly associated with cutaneous nevi (mole) counts, UV damage response and accordingly susceptibility of individuals to develop melanoma. Currently the functional impact of genetic variants in the genes IRF4, PLA2G6 …

Investigating differences in downstream signalling mediated by two isoforms of FGFR2 in endometrial cancer
FGFR2 encodes two alternatively spliced isoforms that differ in their ligand binding domain and the combination of tissue specific expression of these isoforms and tissue specific expression of the FGF ligands is the foundation of normal paracrine signalling. Isoform switching from FGFR2b (inclusion of exon 8) to FGFR2c (inclusion of exon 9) occurs in tumorigenesis as it establishes an autocrine loop in epithelial cancer cells.We have previously published a detailed investigation into differences between wildtype FGFR2b and mutant FGFR2b following …

Uses of exosomes as therapeutic delivery systems
Exosomes are small (40-120 nm), stable, lipid bilayer nanovesicles identified in biological fluids (e.g. in milk, blood, urine and saliva). They contain a diverse array of signalling molecules, including mRNA, microRNA (miR), proteins, lipids and membrane receptors, and they interact with target cells via multiple pathways. The cargo of circulating exosomes can be indicative of a specific tissue’s health status, granting the capacity for use of exosomes as a tool for disease diagnosis. Moreover, they have many of the features …

Improving cow fertility: targeting exosome-responsive pathways
Exosomes are small (40-120 nm), stable, lipid bilayer nanovesicles identified in biological fluids (e.g. in Until recently, genetic selection in dairy cows has focused primarily on milk production traits, with very few countries including functional traits such as fertility in selection indices. Poor reproductive efficiency in dairy herds results in fewer calves, reduced milk production, high involuntary culling rates and increased cow maintenance costs. The need for, and utility of, markers of early onset of diseases (or vulnerability to diseases) …

Can virus-based defective interfering particles (DIPS) be used to treat dengue infection?
Infection by dengue virus causes incapacitating and potentially dangerous acute disease in humans. Dengue is a mosquito-borne infectious disease with about 100 million serious clinical infections annually. Considerable effort in drug development is underway, but no effective drug therapy is available. A major difficulty for drug development is the rapid evolution of RNA viruses, like dengue virus, which presents a major challenge for controlling virus transmission and infection using conventional pharmaceuticals and vaccines.This project is based on the observation that …

Potential for defective interfering particles (DIPS) to interrupt mammal-mosquito transmission of dengue virus
Dengue is a major mosquito-borne disease affecting 390 million people annually across 100 countries. Disease results from infection with dengue viruses, which are single positive-stranded RNA viruses in the family Flaviviridae. Defective interfering particles (DIPs) are virus-like particles with greatly reduced genomes that are byproducts of RNA virus replication and replicate only in the presence of standard virus (Vignuzzi and Lopez 2019, doi: 10.1038/s41564-019-0465-y). DIPs occur naturally during Dengue infection (Li et al. 2011, doi: 10.1371/journal.pone.0019447) and suppress DENV replication …

Determining the theapeutic efficiency of epigenetic drugs in ovarian cancer
Because cancer and many diseases arise from a combination of genetic propensity and the response of cells to external factors mediated through changes to the expression of key genes, it is important to understand epigenetic regulation. The epigenome is crucial to the changes of gene expression and there is now strong evidence that epigenetic alterations are key drivers of cancer progression. However, very few drugs targeting epigenetic modifiers have been successful, in part due to the lack of effective means …

Metagenomic analysis of bacterial contamination screening pooled platelets
Bacterial sepsis is second only to ABO incompatibility as a cause of death from transfusion. Bacterial contamination of platelets is recognised as the most significant residual infectious risk of transfusion in developed countries. Bacterial Contamination Screening (BCS) has been required for testing of pooled and apheresis platelets manufactured by the Blood Service since April 2008. International microbiological culture studies suggest that the incidence of bacterial contamination ranges from 1:3000 to 1:1000 units of apheresis platelets and 1 in 600 to …
