Structure And Function Of A Cancer-linked Co-regulator Complex
Funder

Funding Amount
$1,282,475.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
An Integrative Structural Biology Approach To Understanding The SAGA Transcriptional Master Regulator Implicated In Cancer And Development

Funding Amount
$318,768.00
Summary
Stringent control of gene expression ensures the harmonious life of all human cells. Loss of this control leads to development of a chaotic genome, characteristic of diseased states such as cancer. In this proposal, we aim at capturing and understanding the first key steps of the mechanism that, if dysfunctional, leads to aberrant gene expression. We will use cutting-edge structural bio-imaging to answer questions of fundamental importance to human health and pathologies.
Molecular Basis For Stress-induced Gene Regulation—a Model System To Understand Transcriptional Deregulation In Cancer And Neurological Disease
Funder

Funding Amount
$384,076.00
Summary
Deregulated gene transcription plays a critical role in cancer formation. It is therefore important to understand the molecular basis of gene transcription and how tumour cells hijack the process. In this Project, we will study the molecular basis of stress-inducible gene expression. This is particularly important for understanding the molecular basis of cancer as stress-inducible genes are activated by transcription factors implicated in breast, colon, lung, and prostate cancers.

How Do BET Bromodomain Proteins Regulate Gene Expression?
Funder

Funding Amount
$586,791.00
Summary
This project is aimed at defining the biochemical mechanisms of action of a class of gene regulatory proteins (BET proteins) that are currently considered to be exciting drug targets for a range of diseases, predominantly cancer. A better understanding of the means by which BET proteins regulate gene expression will be important for the rational design and application of drugs that selectively target the proteins.
Protein-RNA Interactions In Antiviral Cellular Defence And Gene Regulation

Funding Amount
$705,501.00
Summary
Protein-RNA interactions play key roles in antiviral cellular defence and inflammation. Investigation of these molecular interactions will lead to new therapeutic targets and means of combating virus-related disease and inflammatory disorders.
Mechanisms Of Gene Regulation - Structure, Function And Design
Funder
National Health and Medical Research Council
Funding Amount
$697,209.00
Summary
The human genome contains at least 20000 genes. The activity of these genes must be tightly controlled throughout an individual’s life and problems with the regulation of genes lie at the heart of many common and serious diseases, including most forms of cancer. My program of research is focused on understanding the mechanisms underlying gene regulation and on the design of new reagents that could be used to manipulate the activity of genes that behave aberrantly in disease states.
LMO2-containing Complexes In Leukemia And Blood Cell Development

Funding Amount
$803,652.00
Summary
Childhood T-cell leukemias have a poor prognosis for recovery. We are determining, with atomic level precision, how the proteins Lmo2 (also linked to prostate and other cancers) and Tal1, and their binding partners contribute to both normal blood cell development and T-cell leukemia. With this information we are developing reagents that can be used to disrupt disease-causing complexes, and which will lead towards the development of new, specific, therapeutics for leukemias and other cancers.
How does an essential histone variant effect changes in gene expression? The mechanisms that determine how genes are switched on and off in different tissues and at different times are not clearly known. It is well established that gene expression patterns are determined in part by the molecular signals transmitted by variation in the proteins that package eukaryotic DNA. Our aim is to understand new aspects of these mechanisms that revolve around how our DNA is packaged. This foundational knowl ....How does an essential histone variant effect changes in gene expression? The mechanisms that determine how genes are switched on and off in different tissues and at different times are not clearly known. It is well established that gene expression patterns are determined in part by the molecular signals transmitted by variation in the proteins that package eukaryotic DNA. Our aim is to understand new aspects of these mechanisms that revolve around how our DNA is packaged. This foundational knowledge will deepen our understanding of gene regulation in all complex organisms and will inform future efforts to rationally modulate gene expression patterns in agriculture, research and other important areas.Read moreRead less
