Defining Mechanisms Of Androgen Receptor Action That Impede Breast Cancer Progression

Funding Amount
$770,619.00
Summary
Androgens (A), commonly considered male hormones, are present in women and may protect them from developing aggressive breast cancer by opposing the cancer-promoting effects of estrogen (E) hormones. We propose that a disturbance in the balance between A and E action in breast cancer worsens the disease and results in a poor outcome for afflicted women. We aim to define how A and E hormones interact in breast cancer, with a view to developing new ways to treat breast cancer and predict outcome.
Nuclear Receptors And Triple Negative Breast Cancer

Funding Amount
$681,979.00
Summary
This project will explore the potential for a nuclear receptor known as the thyroid receptor to suppress growth of breast cancer using cell culture models and mouse models. We hope to show that activating the thyroid receptors leads to a reduction in breast cancer growth providing evidence that the thyroid receptor pathway could be targeted for therapy.
The FGFR Family As Drivers And Biomarkers Of Regorafenib Response In Gastric Cancer.

Summary
The drug regorafenib has recently emerged as a potential new treatment for patients with gastric (stomach) cancer. We have discovered that gastric cancer cell lines which express high levels of members of the FGFR family are highly sensitive to this drug. This project will define the potential of targeting the FGFR family in gastric cancer,the value of FGFR1-4 as markers of regorafenib response, and develop strategies for enhancing regorafenib activity in this difficult to treat disease.
Colorectal cancer (CRC) is one of the most common causes of cancer-associated death in the world. We aim to understand why some CRC patients stop responding to EGFR therapy. In particular, we will study small molecules called cytokines that are produced by the tumour microenvironment and determine if the inhibition of these cytokines can over-come the acquired resistance to therapy. Our goal is to identify new ways to improve the current treatment options for CRC patients.
Defining Ubiquitin Ligase Substrates: New Therapeutic Strategies In Breast Cancer

Funding Amount
$598,163.00
Summary
Current cancer therapies use drugs that target both tumor cells and rapidly growing normal cells – causing side effects and limiting effectiveness. Newer treatments aim to target molecules that are unique to tumor cells, leaving normal cells unharmed. This project will study a process that tags proteins for destruction by a cellular recycling system, which is often disrupted in cancer. This research will not only help us understand how cancer develops, but also identify new targets for therapy.
Toll-like Receptor 2 Signalling As A Potential Therapeutic Target In Gastric Cancer

Summary
Stomach cancer is the fourth most deadly cancer in the world. Stomach cancer is closely linked with inflammation, and we have shown that a key inflammatory molecule, called toll-like receptor 2 (TLR2), can drive the development of stomach cancer. However, this occurs in a non-inflammatory manner. My research aims to understand how TLR2 is involved in the progression of stomach cancer, with the ultimate goal to find an early biomarker of disease, and to develop better therapies.
Antibody-based Inhibition Of ADAM10 As Cancer Immunotherapy

Funding Amount
$652,788.00
Summary
Despite our advances in understanding the molecular basis of cancer, treatments for metastatic cancers are limited, emphasising an urgent need for strategies targeting several oncogenic pathways. We generated monoclonal antibodies effectively blocking the activity of ADAM10, an oncogenic cell surface protease that activates tumour growth, invasion and metastasis through multiple pathways. Here we describe the strategies that progress these antibodies as lead therapeutics for clinical testing.
Novel Dual Domain Targeting Strategies Against ErbB Receptors
Funder

Funding Amount
$711,216.00
Summary
This project will develop innovative strategies to treat cancer through novel antibodies to erbB growth factor receptors, and identify ways to improve conventional treatments.
This Fellowship will focus on the development of novel therapeutics for cancer, and identify mechanisms for selection of treatments best suited to individual patients. It will also develop innovative strategies to identify cancer through molecular imaging techniques.
ADAM Metalloprotease Inhibition For Treatment Of Colorectal Cancer

Funding Amount
$770,925.00
Summary
Colorectal cancer (CRC) causes over 4000 deaths/year, typically from developing drug resistance and spreading to other organs (metastasis). These processes involve tumour cells called cancer stem cells (CSCs), which rely on specific cell surface proteins for survival and function. We are developing antibodies against one of these type of proteins, to test in mouse models of CRC. These already show promise in targeting CSCs and inhibiting drug-resistance and metastasis in mice.
