Summary
It is thought that understanding cancer metabolism will reveal vulnerabilities that can be exploited in the clinic. Indeed, compared to most normal cells, cancer cells utilise different fuels to sustain proliferation and to adapt to their environment. Herein we have discovered a molecular switch that regulates the key metabolic enzyme IDH1 and show this controls tumour growth. Given this switch may be active in 50% of cancers we anticipate our work will have significance to many cancer types.

Mechanisms Of Hedgehog Signaling In Small Cell Lung Cancer

Summary
Some types of lung are very sensitive to chemotherapy, however they frequently relapse, at which time they become resistant to this form of treatment. This project investigates how embryonic signaling pathways, that normally function to regulate organ formation in development, are activated and promote tumor regrowth following chemotherapy for lung cancer.
Molecular Characterisation Of Telomere Trimming And Its Role In Cell Proliferative Capacity

Summary
Telomeres are protective structures at the ends of chromosomes. Telomere length is a major determinant of how many times a cell can proliferate. We have recently discovered a rapid telomere shortening process that we have called telomere trimming. We will analyse the molecular details of this process to determine whether it could be used to shorten telomeres and stop cancer cell proliferation, and whether blocking it could increase cell proliferation in patients with short telomere syndromes.
Tapping The Power Of Pluripotency: The Role Of HMGA1 In Stem Cell Self-renewal And Cell Fate Transitions

Summary
Stem-cell-based therapies have great potential as new treatments for degenerative and genetic diseases. However, to ensure we move in the right direction, we need a detailed understanding of stem cell properties. We have recently identified a novel mechanism for controlling stem-cell-like properties in both normal and cancer stem cells. In this project, we will further investigate this new means of controlling stem cells, which could revolutionise future therapeutic strategies for many diseases.
Congenital brain vascular malformations are a common cause of stroke and death in young patients. This project aims to develop a new treatment for these lesions that does not require surgery. We will use focussed radiation to change the cells lining the abnormal vessels so that they can be targeted with a new treatment that causes blockage of the vessels and prevents haemorrhage.

Summary
Mesenchymal stem cells are a population of cells that reside in various organs in the body and are thought to contribute to tissue repair. However little is known about the developmental origins and identity of these cells. I will investigate where these cells originate from, their molecular identity and how they relate to blood development. These findings will help in developing protocols to manipulate these cells to repair damaged organs. This study will also inform current attempts to generat ....Mesenchymal stem cells are a population of cells that reside in various organs in the body and are thought to contribute to tissue repair.

Cells are building blocks of living things and require signalling pathways to communicate their functions. We discovered a new signalling pathway in flies that remarkably exists in yeast and plants to more complex organisms like mice and man. We will study this new signalling pathway in flies to find out how and why it communicates in cells. As flies and humans share similar genes, our studies will inform how this previously unknown signalling pathway functions from simple to complex organisms
Resetting The Tipping Point: Converting Immune Checkpoint Non-responders Into Responders.

Summary
Although immunotherapy has recently shown a breakthrough in the treatment of lung cancers, with long-term full regression of the cancer in some patients, most patients unfortunately do not respond. In this proposal, we want to characterise the events that occur in a cancer that is cured by immunotherapy, while it regresses. By subsequently reinforcing those processes, we aim to tip the balance towards a response, thereby increasing the cure rate.
The Hippo/Yap Pathway Reprograms Glucose Metabolism To Fuel Tissue Growth.

Summary
Liver disease is a common cause of sickness and death in Australia. While factors critical to liver function are known, the cellular networks responsible for causing liver cancer are largely undefined. Our studies will use zebrafish as a model to study how the circuit known as the Hippo pathway reprograms metabolism to promote liver cancer. These studies will enhance our understanding how metabolism regulates liver growth and identify therapeutic targets to combat liver cancer.
