Summary
Despite advances in treatment and diagnostics breast cancer (BC) remains one of the leading causes of death in women. Metastases and tumour blood vessel recruitment are linked. Work by Dr Mellick and others has shown that host bone marrow contributes endothelial progenitor cells (EPCs) to tumour vasculature. The chemokines and their receptors, which differentiate EPCs from tumour vessels, will be knocked down in the tumour cells and EPC progenitors with the aim of preventing tumour spread.
HIV-1 Transcriptional Gene Silencing By Promoter Targeted Si/shRNAs: Uncovering Mechanisms, Optimising Delivery Systems, Assessing In Vivo Efficacy.

Summary
Current therapy for HIV is effective but must be taken for life. If therapy is stopped the virus comes back immediately from reservoirs not affected by current drugs. These fluctuating levels of virus are associated with increased illness and death. We are exploring a method of inducing prolonged viral latency using short double stranded RNA molecules. We propose to understand the mechanism of action of these possible therapeutics and to develop these constructs towards use in clinical trials.
Non-viral Vectors For Targeted Delivery Of RNAi Nucleotides To Cervical Cancers

Summary
RNA interference (or gene silencing) is a new technique whereby we are able to turn off the expression of a particular gene either temporarily or permanently. Cancer is basically a genetic disease where certain protective genes are lost or cancer-causing genes expressed. Gene silencing holds great promise in the treatment of genetic disorders, infectious diseases and cancer. Cervical cancer is caused by infection with the human papillomavirus and the expression of two cancer-causing genes.

Cancer is basically a genetic disease where certain protective genes are lost or cancer-causing genes expressed. Gene silencing holds great promise in the treatment of genetic disorders, infectious diseases and cancer. Cervical cancer is caused by infection with the human papillomavirus and the expression of two cancer-causing genes. Using RNA interference we can turn off the expression of these two genes which results in the death of the cancer cell. We are also able to cure mice of tumours derived from human cervical cancer. The major issue with gene silencing is how to deliver it effectively to patients. Here we are investigating novel nanoparticulate systems to deliver this new gene-inhibiting drugs preferentially to the tumour site.Read moreRead less
Structural And Functional Studies On RNA Nuclear Retention Mediated By Paraspeckles: A Novel Gene Regulation

Funding Amount
$290,978.00
Summary
Dynamic interactions between proteins and nucleic acids are essential process in gene regulation, where aberrant regulation leads to various diseases including cancers. The project aims to examine the interactions between paraspeckle proteins and nucleic acid molecules via determination of the structures of protein-nucleic acid complexes at the atomic level. The results will provide a better understanding of a recently discovered gene regulation mechanism and a basis for new gene therapy.
Unlocking Hidden Cancer Drivers Using Transcriptome Data

Summary
New sequencing technologies allow us to get an unbiased look at the molecular signalling in a tumour. However this information is very complex and need specialised methods in statistic and computation in order to make new discoveries. Here will will develop analysis methods to find novel transcriptional variants in cancer and then test them in the lab in order to understand if our discoveries are responsible for causing cancer.
Understanding The Role Of RAS Mutations In Thyroid Cancer.

Funding Amount
$463,854.00
Summary
My fellowship will examine the association of RAS mutations in thyroid cancer. RAS proteins are the most mutated in cancer and I will investigate how they work in thyroid cancer. RAS mutated thyroid cancer is more likely to cause death. This grant will be based in the pioneering lab of Prof Fagin at Memorial Sloan Kettering Cancer Center and the Garvan Institute of Medical Research. It is hoped by understanding these mutations, new treatments for thyroid cancer can be developed.
A Novel Molecular Mechanism Controlling Myelopoiesis

Funding Amount
$878,439.00
Summary
The immune system is comprised of many different cell types, each with a specialised function. Many are short-lived and must be continually replenished throughout life. Abnormalities in this process underlie many human diseases, including immunodeficiency, autoimmunity and cancer. We have discovered a novel molecular mechanism that is critical for the production of immune cells. This project will investigate how this mechanism is controlled and the impacts on myelodysplastic syndromes.

Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. Several of these regions do not contain any known protein coding genes, suggesting that non-protein coding genes could be responsible for the associated risk. The aim of this proposal is to identify and characterise these non-coding genes. Understanding how sequences variations in these novel genes contribute to breast cancer will provide novel a ....Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer.

Summary
The immune system is comprised of many different cell types, each with a specialised function. Many are short-lived and must be continually replenished throughout life. Abnormalities in this process underlie many human diseases, including immunodeficiency, autoimmunity and cancer. My laboratory seeks to understand the molecular pathways that control development of immune cells and to identify the defects that lead to disease.
