Mechanisms Regulating Mitochondrial Outer Membrane Permeabilisation During Programmed Cell Death

Funding Amount

Summary
Apoptosis is a form of cell suicide that is vital in human development and health by removing damaged or unwanted cells in a regulated manner. Disturbances in this pathway are known to be the cause of cancers and other diseases. This research will investigate how the pivotal step in cell death, termed mitochondrial outer membrane permeabilisation (MOMP) is regulated.
Structure And Function Of A Cancer-linked Co-regulator Complex

Funding Amount
$1,282,475.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.

Developing Novel Molecules That Target Hormone Receptors As An Alternative Cancer Therapy

Funding Amount

Summary
A promising class of cancer drugs target heat shock protein 90 (Hsp90) and prevent Hsp90 from maintaining its ~100 proteins involved in cell growth. However, all current Hsp90 chemotherapeutics non-selectively target proteins maintained by Hsp90, and induce a cell rescue mechanism involving Hsp70. We describe the development of a novel molecule that will selectively control cell growth and prevent cell rescue via a unique Hsp90 regulated mechanism.
Prion-like Behaviour In Immunity: Super-sized Signalling Platforms?

Funding Amount
$611,995.00
Summary
Prions have been mostly associated with pathologies but recent discoveries show that prion-like behaviour may be beneficial, enhancing our immune response for example. To test this, we want to systematically explore all human proteins involved in the defence against pathogens, find new prion-like trends and probe their role in the innate immune response.
Endosomal Protein Trafficking Complexes - Therapeutic Targets For Novel Antivirals
Funder

Funding Amount
$543,727.00
Summary
The enzyme Vps4 is a key target for the development of new antiviral drugs targeting a family of enveloped viruses that includes HIV (17,000 cases), Hepatitis B and C (420,000 cases) and Herpes Simplex (type I, II - 1.3 million cases). This project will use high resolution microscopy to investigate the molecular structures that enable infection by these and other Vps4-dependent enveloped viruses.
Assembly And Misassembly Of Mitochondrial Respiratory Chain Complex I

Funding Amount
$520,520.00
Summary
Mitochondria are the powerhouses in our cells. They burn the carbon fuels we eat and store the energy by making ATP that is used for functions such as muscle contraction and triggering of nerves. Mitochondrial Complex I is a molecular motor that helps to make ATP. “Mitochondrial disease” is often seen when Complex I is not built properly and this results in early childhood death. In this project we will study how Complex I is built and how the mitochondria responds to assembly problems.

Mitochondrial Quality Control In Parkinson’s Disease: The Molecular Mechanisms Of PINK1 And Parkin
Funder

Funding Amount
$558,721.00
Summary
Parkinson’s disease is a degenerative disorder of the central nervous system in which the underlying cause is mostly unknown. To pave the way to a better understanding of what goes wrong, this study will investigate the function of PINK1 and Parkin, two genes that are mutated in inherited forms of the disease that play important roles in maintaining cellular health. The results of this study will be used in exploring new therapeutic targets for the treatment of Parkinson’s disease symptoms.
