Summary
Non-alcoholic fatty liver disease (NAFLD) occurs in overweight people, diabetes and with high blood pressure and raised cholesterol. This research is about how cholesterol in liver cells interacts with long chain fatty acids to cause injury and inflammation (steatohepatitis, NASH) in NAFLD.
C-Jun N-terminal Kinase Actions In The Response To Stress

Summary
All cells in our body sense and respond to stressful changes in our environment. We are focused on enzymes called JNKs that relay this information, and so form part of the key response pathways. JNKs are now being evaluated as new drug targets for the treatment of diseases including diabetes and stroke, but we know very little about how JNKs work in stressed cells. We will define new partners for the JNKs and in so doing reveal new information on the stress-activated events they regulate.
New Insights Into Mechanisms That Coordinate Kinase Signalling And Molecular Motors In Mitosis: A Novel Role For The Protein Scaffold WD-repeat Protein 62 (WDR62).

Summary
Proteins perform all functions within a cell. Commonly, different proteins are assembled into large complexes to carry out processes, such as cell division, with significant implications for human health. Scaffold proteins facilitate the proper assembly of large complexes but are a poorly understood protein class. We will perform molecular analysis of a newly discovered scaffold, WDR62, to define how it drives cell division and reveal how this can be exploited to develop new anti-cancer drugs.
C-Jun N-terminal Kinase Regulation Of Microtubule Destabilizer, Stathmin - A Novel Cytoprotective Pathway

Summary
The loss of heart muscle cells during heart attack and heart failure worsens the severity of heart disease. We will study how to protect heart muscle cells by identifying the molecules involved in controlling survival responses. We will use this knowledge to prevent heart muscle cells from dying when exposed to a range of normally harmful conditions. Our study has the potential to prevent heart muscle cell loss, improve heart function and prevent muscle damage in heart disease.
Distinct Pathogenic Roles For JNK Signalling In Glomerular And Interstitial Injury In Kidney Disease.

Summary
Our studies have identified a stress-activated mechanism (the JNK signalling pathway) as a therapeutic target in the treatment of kidney disease. The current project will define the role of JNK signaling in individual cell types in the development of different types of kidney disease. These studies will provide new insights into the pathogenesis of kidney disease, and will be highly relevant to other diseases, including atherosclerosis, lung fibrosis and arthritis.
Suppressor Of Cytokine Signalling (SOCS4) Is A Critical Regulator Of The Anti-viral Immune Response

Funding Amount
$616,912.00
Summary
The SOCS proteins are negative regulators of cytokine signalling and immune cell development and function. SOCS4 is the last remaining SOCS protein for which there is no described function or intracellular target. We intend to use well-defined acute and chronic viral disease models, and investigate the role of SOCS4 in infection in order to unravel its function. We will also search for its binding partners and intracellular targets, and determine the signalling pathways regulated by SOCS4.
Molecular Characterisation Of A New Survival Pathway In Haematopoietic Cells

Summary
It is critical for normal health that cells regulate their responses to changes in the the extracellular environment. Receptors on the cell surface are triggered by specific proteins called cytokines, and relay information to the cell interior. These messages include signaling whether cells should survive and proliferate. Inappropriate activation of signals for survival and proliferation is a hallmark of cancer. We are investigating a new survival signal and how this contributes to the survival ....It is critical for normal health that cells regulate their responses to changes in the the extracellular environment. Receptors on the cell surface are triggered by specific proteins called cytokines, and relay information to the cell interior. These messages include signaling whether cells should survive and proliferate. Inappropriate activation of signals for survival and proliferation is a hallmark of cancer. We are investigating a new survival signal and how this contributes to the survival of normal cells and to diseases such as leukaemia.Read moreRead less
