Summary
Receptors are cell-surface molecules that enable the cell to receive chemical messages from the outside environment and transmit these signals to the inside of cell. These messages tell the cells to grow, divide or die. The Epidermal Growth Factor Receptor is linked to a variety of cell signalling pathways that are critical to the normal functioning of cells. Conversely, abberations in Epidermal Growth Factor-mediated cell signalling leads to many types of cancers.

These messages tell the cells to grow, divide or die. The Epidermal Growth Factor Receptor is linked to a variety of cell signalling pathways that are critical to the normal functioning of cells. Conversely, abberations in Epidermal Growth Factor-mediated cell signalling leads to many types of cancers. A basic understanding of how the receptor is turned off or on is essential to designing drugs that can specifically inhibit its hyperproliferative response. High resolution structures of a key part of the Epidermal Growth Factor Receptor have identified several structural forms of the receptor that are providing valuable clues as to the structural basis for receptor activation. Armed with this information and advanced microscopic imaging technology we are in the unique position to probe receptor activation in living cells. This project seeks to determine which structural form of the receptor is responsible for transmission of cellular messages and how it is impaired in cancerous cells.Read moreRead less
Novel Fluorogenic Probes For The Selective Detection Of Pathogenic Bacteria

Funding Amount
$542,489.00
Summary
Current methods for the detection of multi-resistant organisms either require expensive instrumentation and expert analysts or are simple, but require 24-48 hours for bacterial identification. The ideal surveillance method would be cost effective, rapid, reliable, and simple to perform. This project aims to prepare a range of fluorescent substrates for incorporation into growth media which will then be evaluated for the specific identification of individual multi-resistant organisms, e.g. MRSA.
The Role Of Nuclear Architecture In The DNA Damage Response

Summary
The goal of the proposed research is to understand how dynamic changes to the chromatin genome packaging network, interact with the DNA damage response and gene expression machinery, to repair damaged DNA and the impact this has on cancer biology. To do so we are combining cutting edge molecular biology techniques with innovative novel microscopy methods developed by our research team, that far exceed the spatiotemporal resolution currently used to study chromatin biology.
Unravelling Mechanotransduction Pathways In The Heart

Funding Amount
$949,956.00
Summary
This project addresses the still unresolved question of involvement of mechanosensitive ion channels in heart hypertrophy and arrhythmias including ventricular arrhythmias. These pathological conditions are a cause of a broadening fiscal healthcare burden in Western societies. Consequently, investigating the role of this class of ion channels in heart disease presents a priority for medical science and a great opportunity to improve the health outcomes for the Australian people.
