Summary
Diabetes mellitus is common in our community. It causes much premature death and loss of quality of life. Recent data from Australian studies show that ~7% of adults over 25 years, and ~20% of people aged over 65 have diabetes, and diabetes in both children and adults is increasing in Australia. A critical problem caused by diabetes, irrespective of its cause, is that blood glucose levels are higher than normal. High blood glucose contributes to much of the damage to body tissues and to the earl ....Diabetes mellitus is common in our community. It causes much premature death and loss of quality of life. Recent data from Australian studies show that ~7% of adults over 25 years, and ~20% of people aged over 65 have diabetes, and diabetes in both children and adults is increasing in Australia. A critical problem caused by diabetes, irrespective of its cause, is that blood glucose levels are higher than normal. High blood glucose contributes to much of the damage to body tissues and to the early death that can occur in diabetes. Unfortunately, given our current treatment methods, in only a small number of patients can glucose levels in the body be consistently controlled into the normal range. How does high blood glucose cause damage to the body and its different tissues? This is a complex process. One way that damage occurs is through an increase in some of the growth factors in the body. In diabetes, high blood glucose can increase the production of some growth factors in an uncontrolled way. In turn, these growth factors then cause tissue damage. One of the growth factors that can be increased by the high glucose in diabetes is called connective tissue growth factor, or CTGF. CTGF can cause scars to form in tissues, and it is increased in diabetes in humans. Through NHMRC sponsored post-doctoral research over the past four years, Dr Twigg has published findings showing pathways by which diabetes causes increases in CTGF, and ways in which CTGF then causes tissue scarring. The current grant proposal presents new data showing further novel pathways by which CTGF is activated by diabetes and ways in which CTGF causes scarring. The pathways involved will be studied in detail in the project. In addition, methods to block CTGF and its harmful effects in diabetes will be developed in this work. By controlling CTGF, it is envisaged that damage to tissues will be reduced, leading to improved quality and quantity of life for people who have diabetes.Read moreRead less
Sugars in the real world: are cultured cancer cells a good model system for studying protein glycosylation? It is challenging to study errors in metabolism in human beings, so researchers use cells grown in the laboratory to understand disease processes. This project will determine if cultured cells accurately reflect the real changes to cell surface sugars that occur in all cancers, and the effect of these changes on the invasive properties of colon cancer cells.

An automated 3D electron microscopy facility: The aim of this project is to establish the next generation of electron microscopy facility, with a fully automated tool enabling 3D imaging. The automated serial section system incorporated in a scanning electron microscope circumvents the limitation of transmission electron microscopy, which provides unique insights into molecular structures and cell components at high resolution, however, the area and volume are limited in size to a few microns. This new type of microscope can image whole organisms and be used by non-electron microscopists. It will be housed in an open access facility and will meet a growing demand for 3D electron microscopy.Read moreRead less
Identifying genes controlling the regulatory and metabolic interactions between the energy organelles of the leaf. Plant energy metabolism underlies the synthesis of many important products in crops, and subtle changes in metabolism can enhance key plant traits, such as germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments.

Plant energy metabolism underlies the synthesis of many important products in crops, and subtle changes in metabolism can enhance key plant traits, such as germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments. Furthering our understanding on the complex interplay of genes controlling energy metabolism and its impact on leaf function has potential outcomes for smart genetic manipulation either by classical breeding or genetic transformation. There are more than 10,000 genes of unknown function in plant genomes and this represents a tremendous untapped resource for future Australian R&D outcomes and insights from this research proposal will have application to all plant-based agriculture.Read moreRead less
Molecular control of embryonic diapause. Many species can halt growth of the early embryo (diapause). This project will use novel animal models and new proteomics techniques to clarify what signals from the uterus control diapause of the embryo. This may uncover new mechanisms for cell regulation that will be relevant to the biology of stem cells, cancer and reproductive technologies.

Responding to industry calls for improved methods of detecting and managing infertility in both stallions and mares, this project aims to provide a platform for competitive collaborations between universities, biotechnology companies and horse breeders: the end-users of technological developments in equine reproduction. The Thoroughbred and Standardbred breeding industries contribute over $6.5 billion per annum to the Australian economy and employ thousands of staff across their value chains. However, these industries suffer from breeding program inefficiencies that amount to over $800 million in annual losses. Expected outcomes are novel reproductive technologies and specialised research capabilities that will make the Australian equine industry a global leader.Read moreRead less
Discovery of novel myokines by innovative proteomic analyses. This project will utilise sophisticated techniques to identify novel proteins that are released from contracting skeletal muscle termed myokines. It is expected the project will identify numerous novel proteins that may enhance our understanding of human biology.

This project aims to dissect how genes interact with the environment to control healthy ageing using a multidisciplinary approach combining state-of-the-art omics technologies, metabolic and ageing phenotyping and genetic analysis and a highly diverse model system. The project is expected to establish fundamental new understanding of the ageing process by identifying genes that regulate ageing either alone or in response to diet; by defining the mechanism by which such genes control ageing and by identifying biomarkers that predict different ageing outcomes. This knowledge will contribute to future strategies based on genetic testing and biomarkers to optimise healthy ageing in humans. Read moreRead less
