Giant viruses in the human gut microbiome
The human body is home to a vast ecosystem of microorganisms including bacteria, archaea, fungi, viruses, and bacteriophages that make up the human microbiota. These microbes and their collective genetic material, known as the microbiome, influence a wide range of physiological functions including nutrient production and absorption, the development and regulation of our immune system, protection against potential pathogens, and even our mood and mental health. While distinct microbial communities exist throughout the body, the gut microbiome has gained particular …

Characterisation of a novel protein co-amplified with the n-MYC oncogene
The MYCN oncogene is amplified in a number of tumour types, including Neuroblastoma (NB) and Neuroendocrine Prostate Cancer (NEPC), where it is associated with worse patient prognosis, as compared to non-amplified tumours. However, the high expression of MYCN (encoding the n-MYC protein) alone in non-amplified tumours is associated with better patient prognosis and less aggressive disease. This suggests that other genes co-expressed in MYCN amplified tumours may be responsible for mediating the aggressive traits of n-MYC. Our team has identified …

Identifying emergent ecosystem responses through genes-to-ecosystems integration at Stordalen Mire
Permafrost thaw induced by climate change is predicted to make up to 174 Pg of near-surface carbon (less than 3m below the surface) available for microbial degradation by 2100. Despite having major implications for human health, prediction of the magnitude of carbon loss as carbon dioxide (CO2) or methane (CH4) is hampered by our limited knowledge of microbial metabolism of organic matter in these environments.Genome-centric meta-omic analysis of microbial communities provides the necessary information to examine how specific lineages transform …

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 …

Illuminating the microbial world using genome-based fluorescence microscopy
Our understanding of microbial diversity on earth has been fundamentally changed by metagenomic characterisation of natural ecosystems. Traditional approaches for visualising microbial communities are time-consuming and provide limited information about the identity of specific microorganisms.The proposed research aims to combine single cell genomics and super resolution microscopy for novel, high-throughput, genome-based techniques to visualise microorganisms, plasmids and viruses, with strain level specificity.The application of these highly scalable approaches will provide comprehensive and unprecedented insight into the fine-scale dynamics and evolution …

Adaptive evolution of anaerobic methanotrophic (ANME) archaea mediating methane oxidation in freshwater environments (PhD)
The as-yet-uncultured archaeal lineage Methanoperedenaceae are anaerobic methanotrophs with a key role in mitigating the atmospheric release of methane in freshwater environments. The metabolic diversity of these microorganisms directly links methane with several key biochemical cycles and suggests a remarkable ability of these microorganisms to adapt to diverse environmental conditions.The overall aim of this PhD project will be to uncover the metabolic diversity of the Methanoperedenaceae and to understand the evolutionary mechanisms responsible for these adaptations.Methods and ResourcesThe project will …

Developing in vitro 3D models to understand liver disease
Several studies have demonstrated the appropriateness of 3D organoid cultures over the conventional 2D cultures, the advantages of 3D models include replicating the complex attributes of the liver beyond liver-specific metabolism, such as increased cell density, organization, and cell–cell signalling, O2 zonation.In this project we will establish a novel in vitro 3D model to study hepatocyte biology in the context of liver disease. A more comprehensive approach to investigating the intercellular mechanisms of NAFLD will include co-culture of organoids with …

Identification and functional characterisation of genetic modifiers of iron overload
Iron is an element essential for virtually all life forms; aberrant iron metabolism is linked to many diseases. These include cancers, neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease, iron overload and iron deficiency disorders, iron-loading anaemias, and the anaemia associated with chronic disease. Central to proper iron regulation is the appropriate expression and activity of the liver-expressed regulatory peptide, hepcidin, and the iron exporter, ferroportin (FPN). Modulating the expression and activity of hepcidin and FPN, and their interaction is …

Understanding the role of TGF signalling intermediates in liver and iron-related disease
Transforming growth factor β (TGFβ) and its family members is involved in many phases of liver disease development and iron regulation. We have identified unexplored players in liver disease and iron-related disorders: TGF signalling intermediates. In this project, we build on our exciting findings to examine the molecular mechanisms involved in TGF signalling intermediates-mediated disease progression and their potential as targets for liver and iron-related disease.AimsThis project aims to:examine the expression of TGF signalling intermediates in the liverspecifically deplete TGF …

Renewal and differentiation in human neural stem cells and their application to understanding neurological disorders
The effective regeneration of brain tissue requires an understanding of the factors mediating the damage as well as the integration of new/replacement cells to form new functional neural networks. The isolation and expansion of human stem cells and limited neural lineage differentiation have provided the foundation for strategies in the treatment of neurodegenerative disorders. We utilise iPSC-derived NPCs and patient-derived (Alzheimer’s disease; AD) iPSCs and neural lineage differentiation of hMSCs, iPSC NPCs and AD iPSCs in neuronal and glial culture …

Investigation of genetic factors that contribute to concussion and its outcomes
The health outcomes from traumatic brain injuries (TBIs) and concussion depend on the nature of the injury, but response also varies greatly between individuals, suggesting that genetic factors may play a role. In particular, due to effects of head trauma on balances of ions, neurotransmitters and energy use in the brain, there is suggestion that variation in the genes that encode proteins involved in these pathways, e.g. ion channels, may affect the risk of, as well as response to a …

Investigating DNA repair mechanisms in aging adult stem cells
When we age the DNA repair systems of our cells become down regulated. This results in reduced DNA repair capacity, enhanced rates of mutation load and may lead to the development of chronic aging-associated diseases including osteoporosis, Alzheimer's and cancer(1). So it is no surprise that genome instability and stem cell exhaustion, which also strongly correlates with the accumulation of DNA damage, are considered hallmarks of aging(2).However, we still lack a clear understanding on how the decrease in DNA repair …
