Challenging current dogma on the inheritance of mitochondrial DNA. Mutations in mitochondrial DNA are often used to infer genetic relationships and have been associated with the expression of human diseases. This project examines the exact mechanism of inheritance of mitochondrial genes to enhance biological interpretations and our understanding of the heritability of specific diseases.
Molecular response to interferon beta treatment in multiple sclerosis. Inteferon beta (IFNb) is the frontline drug for treatment of multiple sclerosis. However, in many patients this expensive drug provides no benefit, resulting in unnecessary, uncontrolled disease progression, and in a waste of many millions of dollars each year. A common explanation for this treatment failure is the development of neutralising antibodies (NABs). We will establish the prevalence and effects of NABs in Austra ....Molecular response to interferon beta treatment in multiple sclerosis. Inteferon beta (IFNb) is the frontline drug for treatment of multiple sclerosis. However, in many patients this expensive drug provides no benefit, resulting in unnecessary, uncontrolled disease progression, and in a waste of many millions of dollars each year. A common explanation for this treatment failure is the development of neutralising antibodies (NABs). We will establish the prevalence and effects of NABs in Australian patients, use novel techniques to identify biomarkers for IFNb response, evaluate the diagnostic and therapeutic value of the biomarkers, and develop a new test for NABs. Tailored use of this drug, and possible new therapeutic targets, will result, benefiting the patient and community.Read moreRead less
Impact of the male germ line on the mutational load carried by mammalian embryos. This project examines whether a man's age or exposure to lifestyle factors (alcohol, cigarette smoke and mobile phone radiation) can have a major effect on the health of his children. The project is particularly relevant to the safety of assisted conception procedures used to treat the 1 in 20 Australian men suffering from infertility.
Characterisation of tumour variants of Devil Facial Tumour Disease. This project will take a new approach to cancer research by studying the evolution of Devil Facial Tumour Disease. The results will directly contribute to the conservation management of the Tasmanian devil, as well as generating new information on tumour growth, metastasis and emergence of resistance.
Epigenetics, environment, and evolution. This project will aim to understand how biological information can exist and be passed from one generation to the next without being encoded in the gene sequence, and also how our early environment can modify this so-called "epigenetic" information to alter disease risk.
Beyond the genome: unravelling the intricacies of epigenetic regulation using the honey bee model. Epigenetic mechanisms, such as DNA methylation, provide the interface between genome and environment. Abnormalities in epigenetic regulation lead to cancer and other diseases. The project will be using the alternative phenotypes in honeybees, fertile queens and sterile workers, to understand how dietary factors control conditional gene expression by methylation

Summary
The inheritance of epigenetic information in mammals. This project aims to understand how biological information can be passed from one generation to the next without being encoded in the genes. This may explain questions as diverse as why twins look subtly different and why some families are more likely than others to suffer disease.
The regulation of gene expression by post-translational modification of transcription factors. Different cells in the body express different subsets of our genes, and it is not well understood how cells know which genes to switch on and which to switch off in a given situation. We will investigate the way in which chemical tags are put onto and removed from the molecules that control gene expression in order to direct their function.

High resolution bioanalytical Fourier transform mass spectrometer combined with liquid chromatograph. This project extends a network of advanced technology for bioanalysis that enables discoveries in biotechnology, molecular medicine and biochemistry. The proposed equipment includes the most powerful mass spectrometer (MS) currently available for bioanalysis to complement an existing network of instruments at four universities in Sydney. These include 3 of 4 nodes of the Australian Proteome Anal ....High resolution bioanalytical Fourier transform mass spectrometer combined with liquid chromatograph. This project extends a network of advanced technology for bioanalysis that enables discoveries in biotechnology, molecular medicine and biochemistry. The proposed equipment includes the most powerful mass spectrometer (MS) currently available for bioanalysis to complement an existing network of instruments at four universities in Sydney. These include 3 of 4 nodes of the Australian Proteome Analysis Facility (APAF). The new technology is a missing link in bioanalytical capability where other instruments are not sufficiently sensitive. The instrument will be managed by MS specialists at the Bioanalytical Mass Spectrometry Facility at UNSW (www.bmsf.unsw.edu.au) where access by and training of users is well established.Read moreRead less
Understanding the mechanisms that regulate the human signal recognition particle cycle. The precise cellular localisation of proteins is a fundamental process in cell biology required for survival. The aim of this project is to understand the mechanisms by which the human signal recognition particle delivers newly translated proteins to their cognate cellular location.
