Understanding how cells compact and segregate DNA in vertebrates. How a cell compacts and divides its DNA is still a major unanswered question in biology. This project will determine the way in which a cell compacts its DNA nearly ten thousand fold to allow the faithful and accurate segregation to daughter nuclei.

A new Src, PKCdelta and Akt regulated protease activated receptor system in metastasis. In contrast with localised cancer which can often be cured, curative treatment is generally not possible for cancer that has spread. This project will characterise a protein that drives the spread of cancer and to develop new approaches to treat patients at risk of developing these aggressive tumours that spread to other organs.
Molecular mechanisms regulating Ca2+ channels formed by Orai and STIM proteins. Store-operated calcium channels play a central role in the functions of all animal cells. They participate in generating the cellular responses to hormones, antigens, growth factors and other physiological stimuli. The aims of this project are to elucidate cellular mechanisms that regulate interaction between the molecular components of store-operated calcium channel, Orai and STIM.

They participate in generating the cellular responses to hormones, antigens, growth factors and other physiological stimuli. The aims of this project are to elucidate cellular mechanisms that regulate interaction between the molecular components of store-operated calcium channel, Orai and STIM. Using techniques of electrophysiology and molecular biology we expect to answer a fundamental question how STIM and Orai proteins interact to form functional store-operated calcium channels, and how the expression of STIM and Orai is regulated.Read moreRead less

The aim of this project is to enable a 'first of a kind' cryo-EM platform in Australia enabling high-throughput atomic resolution protein structure determination. This will be achieved by integrating a state-of-the-art Gatan K2 Summit Direct Electron Detection camera system into the established cryo-EM facility managed by the University of Queensland node of the Australian Microscopy and Microanalysis Facility. This will offer unique and significantly improved capabilities for atomic resolution protein structure analysis, and will support a broad range of projects across the biological sciences.Read moreRead less

Determination of cellular mechanisms underpinning cancer cell metastasis through integrated in vivo imaging approaches. Understanding key steps that drive the spread of cancer is critical to improve current treatment strategies. Using cutting-edge imaging technology and in vivo model systems that mimic the disease, this project will pinpoint key events that are susceptible to drug intervention and identify new therapeutic targets.
Molecular mechanisms of cyclic Adenosine Monophosphate (AMP) induced apoptosis. Cyclic Adenosine Monophosphate (cAMP) is an important cellular chemical necessary for cell growth. However, de-regulated cAMP production in response to altered physiology can result in cellular death or apoptosis. This is attributed to the development of certain human diseases and this project aims to understand the molecular mechanism behind this process.
A biological model to understand caveolin-1 and lipid raft function in health and disease. This project will generate a biological model for pathological caveolin-1 action on cell membrane domains called lipid rafts to determine how they trigger chronic diseases such as cancer and diabetes. The tools developed in this project will help Australia find new drug targets for the treatment and prevention of these prevalent diseases.

This project will study structural aspects of key biomolecular complexes at membrane interfaces that are involved with apoptosis (programmed cell death). Malfunctions in apoptosis have been implicated in many aliments including age-related diseases and cancers. Understanding of the molecular and structural aspects of key complexes can pave the way to novel therapies. The approach that will be used is to design new biomimetic outer mitochondrial membranes and use these to study the structure and binding of proteins involved with apoptosis. By studying simple models of complex systems, this project promises to yield detailed information on important biomolecular complexes where structural detail is currently lacking. Read moreRead less
