Summary
Cancer cells turn good genes off and bad ones on: but how do they do this? Recent breakthroughs suggest that noncoding RNA, produced from so-called ‘junk’ DNA, is important. One such noncoding RNA forms paraspeckles, a novel component of the cell machinery. Here, we will pick apart the way paraspeckles are organised and function, to develop them as a prototype for designing anti-cancer treatments against noncoding RNAs.
Nuclear Retention-and-release Of RNA: A Naturally-occurring Mechanism For Controlling Gene Expression

Summary
The deliberate retention of messenger RNA in the nucleus is a newly-discovered biological mechanism used by cells to control which genes are made into proteins, and when. This is a fundamental process in health and disease. The project will employ cutting edge molecular and cellular techniques to discover the principles underpinning nuclear retention. These insights will allow the development of new methods to spatially and temporally control gene expression in diverse gene therapy applications.
Functional Characterization Of The Regulatory Architecture Of Melanoma-associated Loci

Summary
Melanoma accounts for more than 75% of skin cancer related deaths. In Australia, >10,000 new cases are diagnosed yearly. In this proposal, we will apply novel genetic sequencing technologies developed in our laboratory to examine genomic regions that are associated with melanoma development. By focusing on selected areas, we will obtain a much deeper understanding of how these genes are regulated and find new ways of detecting and treating this disease.
We are seeking to understand how the protein ADAR1 functions. When it is mutated, ADAR1 can cause a range of diseases, most notably in a subset of Aicardi-Goutieres syndrome (AGS) patients, an autoimmune disorder affecting the brain, immune system, and skin. We have identified how we think that changes in ADAR1 activity may ultimately cause disease. This application will allow us to test this mechanism experimentally.
Identifying Novel Long-noncoding RNAs Involved In The Development Of Breast Cancer

Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. The aim of this proposal is to identify and characterise these non-coding genes that are modulate breast cancer risk. Understanding how sequences variations that alter these novel genes contribute to breast cancer will provide novel avenues for therapy.
