Triple negative breast cancer (TNBC) is an aggressive disease subtype that lacks targeted therapies. We have identified a protein associated with TNBC termed SgK269 that regulates the transmission of signals instructing the cell to grow and migrate. SgK269 associates with a closely-related protein termed SgK223 to form a signalling complex. The aim of this project is to characterise the role of this signalling complex in TNBC and determine whether it represents a potential therapeutic target.
Transcriptional Effectors Of Oncogenic ERK Signaling In Colorectal Cancer

Summary
This project aims to unravel how one of the most frequently deregulated molecular pathways in colorectal cancer controls the expression of genes required for these tumours to grow and spread. We expect this work to uncover novel therapeutic targets to effectively inactivate this pathway and biomarkers to select patients most likely to benefit from existing therapies.

Summary
Myc is an essential cellular protein but is also a common drive of cancer in multiple tissues. In blood cancers Myc is frequently overexpressed. In contrast, Myc is rarely overexpressed in early stage solid cancers, although often elevated levels at later stages. We will employ unique models of cancer in which Myc can be activated at different set levels at different times during blood cell development to address what the specific contributions of different levels of Myc are in the evolution of ....Myc is an essential cellular protein but is also a common drive of cancer in multiple tissues.

Engineering MYCN Models Of High-grade Serous Ovarian Cancer (HGSC)

Summary
The most lethal type of ovarian cancer, high-grade serous cancer (HGSC), can be divided into four subtypes based on gene patterns. One subtype involves a set of genes/proteins that, in their specific combination, result in activation of a pathway known as MYCN. As most HGSC start in the fallopian tube, we are using fallopian tube material to make new MYCN HGSC models to observe development in the earliest stages. We hope to generate new tests and treatments for this subtype of ovarian cancer.
Characterization Of Ras-Stimulated Macropinocytosis In Pancreatic Cancer

Summary
Pancreatic cancer (PC) is one of the most lethal human cancers, namely due to frequent late stage diagnosis. Thus, there is urgent need to better understand the biology of this disease. Cancer cells are characteristically more reliant on nutrients in order to sustain their growth, making them more vulnerable to inhibition of nutrient supplies. The key aim of this project is to better understand the ways in which PC cells take up nutrients so that these processes may potentially be blocked.
Melanoma Resistance To Combination BRAF And MEK Inhibition Is Driven By Reprogramming Of MAPK Signaling

Summary
Until recently, patients with metastatic melanoma were treated with single agent chemotherapy drugs that produce response rates of less than 10%. New drugs targeting the mitogen activated protein kinase (MAPK) pathway have now shown significant activity, but nearly all patients treated with these new inhibitors eventually develop resistance and progress. This project utilises patient tumour samples to examine the mechanisms of resistance and ways of enhancing the targeted inhibition of the MAPK ....Until recently, patients with metastatic melanoma were treated with single agent chemotherapy drugs that produce response rates of less than 10%.

In melanoma we hypothesise there is a series of as yet unidentified gene fusions which provide oncogenic stimulatory signals that promote tumour growth and that these novel fusion products are excellent targets for the design of new therapies to treat melanoma. The aims of this study are to identify oncogenic fusions in melanoma, to assess which of these are recurrent, and to demonstrate that the resulting fusion proteins provide a selective growth and-or survival advantage to the tumour cell.

Summary
Breast cancer is the most common malignancy among females, affecting 1 in 9 women. Cells normally divide only when they receive a stimulus. The PI3K pathway, which responds to these stimuli, has been implicated in cancer and when mutated induces cells to multiply uncontrollably and invade surrounding tissue. This grant aims to characterise the role of a cancer suppressing gene and a related family member play in the development of human breast cancer.
I am a cell biologist/geneticist focusing on understanding tumourigenesis. Cancer is a multigenic and complicated disease, involving interactions between the tumour and normal tissue. I use the genetically tractable model organism, the vinegar fly, Drosophila, to model cancer in situ and identify novel genes that drive cancer. My 5 year career plan is to use the Drosophila system to model cooperative tumourigenesis in epithelial and brain tissues and translate this to human cancer.
Global Characterization Of The Src-regulated Kinome

Funding Amount

Summary
This proposal aims to use new cutting-edge techniques to globally characterize the impact of a particular cancer-causing gene, or oncogene, on the expression and function of an important family of regulatory proteins, termed kinases, in cancer cells. This will identify proteins critical for cancer cell growth and survival that represent potential targets for therapy.
