The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Ligand Interactions Of The MC1R Receptor And Cellular Consequences For Melanocyte Responses To UV-damage

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. It is essential to understand the complex int ....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.

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.
