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.

Summary
Although it is evident that fair skin types are more susceptible to sun damage, the relationship between sun exposure, skin colour and skin cancer formation is less clear. The genes and processes that determine an individual's skin phototype and the mechanisms involved in the tanning response after UV-exposure of the skin are the focus of this investigation. A major regulator of the response to UV radiation in the skin is the melanocortin-1 receptor.

Microtubule Cytoskeleton In Tumourigenesis And Metastasis

Summary
Over one million cases of lung cancer are diagnosed each year worldwide, making this the leading cause of cancer death. Advanced non-small cell lung cancer (NSCLC) accounts for more than 80% of lung cancer cases. We have identified a protein called ?III-tubulin that is often highly expressed in aggressive and drug resistant NSCLC, and is involved in tumour formation. We will examine how ?III-tubulin is working and identify ways to target this protein to stop tumour growth.
It is seldom the initial cancer that kills the patient; most deaths are due to its metastatic spread throughout the body. Survival after the onset of a brain metastasis is dismal. Current understanding of cancer spread to the brain is poor and yet an ability to inhibit this process would save thousands of lives each year. Using rare tissue resources and cutting-edge technologies, this project will elucidate molecular features of brain metastases that can be exploited to generate new treatments.
Characterisation Of A Novel Oncogene In Breast Cancer

Summary
Breast cancer affects 1 in 8 women in Australia. Cancer cells are able to spread to other sites in the body by a process known as metastasis which is the leading cause of breast cancer death. We have identified a gene which controls breast cancer metastasis and thereby may affect disease outcome. This grant aims to elucidate the mechanisms by which this gene regulates breast cancer metastasis.
Cell survival and death are controlled by two processes known as apoptosis and autophagy. Apoptosis eliminates damaged cells whereas autophagy gets rid of faulty components in the cell. The Bcl-2 proteins regulate both processes. It is well established that dysfunctional Bcl-2 regulation leads to cancer. In this project, we aim to investigate if deregulated Bcl-2 control of autophagy also has a key role in cancer progression and to obtain a molecular picture of how this control is exerted.
