Summary
Common skin cancers such as basal and squamous cell carcinomas (BCC and SCC) are by far the most frequent cancer worldwide and require over a million interventions per year in Australia. This project will identify the skin cells that are most susceptible to give rise to cancer if excessively exposed to the sun and explores ways to prevent cancer formation. This will inform on new strategies to prevent new skin cancer development.
Brain Protection: A new therapeutic approach for Multiple Sclerosis In Multiple Sclerosis (MS), the immune system mistakenly attacks the brain. The immune attacks destroy myelin, the protective coat around electrical cables in the brain (demyelination). Current treatments for MS are only partially effective, and work by reducing the number and severity of these attacks. However, MS-related permanent disability in the majority of sufferers is due to the development of progressive MS, and current ....Brain Protection: A new therapeutic approach for Multiple Sclerosis In Multiple Sclerosis (MS), the immune system mistakenly attacks the brain. The immune attacks destroy myelin, the protective coat around electrical cables in the brain (demyelination). Current treatments for MS are only partially effective, and work by reducing the number and severity of these attacks. However, MS-related permanent disability in the majority of sufferers is due to the development of progressive MS, and current therapies do not reduce this progression. It is believed that one major cause of this permanent disability is permanent myelin loss. Interestingly, we have already shown that the growth factor LIF is made by the body during MS-like inflammation, and that it limits damage by directly protecting myelin-producing cells. However, the bodies own LIF production during inflammation is sub-maximal, because myelin protection can be enhanced by giving additional therapeutic LIF. This suggests that (1) The brain produces a defence response to harmful inflammation and that (2) This defence response can be enhanced therapeutically. We therefore want to define exactly how LIF enhances myelin survival. We have measured the response to LIF in myelin-producing cells, and have discovered that it strongly stimulates the production of the small protein galanin. We will now assess if galanin itself protects myelin and myelin-producing cells, and we will test this both in isolated cells and whole animal models. If galanin production is a major mechanism by which the body tries to limit the damage from abnormal inflammation during MS, then medications that mimic the action of galanin (which are already under development for different reasons) could become a major new therapy for Multiple Sclerosis.Read moreRead less

Bio-metrology and modelling of a complex system: the malaria parasite: This fellowship project aims to develop a cross-disciplinary program to measure, model and manipulate a complex cellular system — sexual differentiation of the human malaria parasite. Combining life and physical sciences with powerful imaging techniques, the project seeks to develop quantitative biochemical, biophysical and modelling techniques to probe a complex system in a way previously not possible. It expects to integrate and correlate thousands of measurements of the dynamic processes inside cells and use these datasets to generate rigorous and sophisticated mathematical models that can predict drivers of commitment for transformation of the parasite to a sexual phase in preparation for transmission to mosquitoes. This holistic approach hopes to deliver new biotechnology and biomedical outcomes, including new ways to combat disease in livestock and humans.Read moreRead less

Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system will enable researchers to study complex behaviour of biological specimens, at the optical resolution limit in plant and animal tissues, leading to basic biology and biotechnology outcomes in biofuels, biomaterials and biomedicines.Read moreRead less

This project aims to understand how 90 per cent of all eukaryotic genes are regulated. The development of a multicellular organism needs thousands of different messenger RNAs, at exactly the right time, in the right set of cells and in the right amount, creating a need for stringent regulation of gene expression. The data generated by the project will show how a massive protein complex of ~50 individual gene products—the general transcription machinery—identifies a gene’s start site, recruits RNA polymerase II and prepares it for transcription of the genetic code. The project is expected to reveal the molecular basis of a process that is as important for flowering in plants as it is for embryonic development in metazoans.Read moreRead less

Billions of cells in the body die daily as part of normal turnover. Dying cells must be rapidly removed, as their accumulation can interfere with normal tissue functions. To efficiently clear dead cells, dying cells can disassemble into smaller fragments that neighbouring cells engulf. Understanding the mechanistic basis and function of dying cell disassembly is expected to generate knowledge of the downstream consequence of cell death. This breakthrough will be important in many fields of research including cell biology and biochemistry, and generate basic knowledge that can ultimately be applied in medical science to understand or treat pathological conditions associated with cell death.Read moreRead less
