Summary
Ovarian cancer is the most lethal gynaecological cancer. Previously, we showed that cancer stem cells are the “beating heart” of the ovarian cancer and are responsible for drug resistance and tumour relapse. The ineffective targeting of these cells by chemotherapy is accountable for the poor clinical outcomes in ovarian cancer patients. This project will define the molecular signals involved in maintenance of cancer stem cells and develop targeted therapies against these cells.
CHARACTERIZATION OF A NEW SUBTYPE OF AGGRESSIVE BREAST CANCER

Summary
Much effort has been invested in the sequencing of cancer genomes, leading to the identification of genes linked to aggressive subtypes. There is now a need to confirm the importance of these genes and to exploit these findings for patient therapies. We have identified a new cancer driver controlling an aggressive type of breast tumour which may act through one carbon/folate metabolism. We aim to map the inner workings of these cancers to devise effective targeted drugs for these patients.
Developing Irreversible Electroporation Non-Thermal Tumor Ablation For Organ-Confined Prostate Cancer Treatment

Summary
IRE is technique for targeted tissue ablation. Electrodes placed into the targeted area deliver intense, brief electric pulses. Nano-scale pores are created in the cell membrane killing the cells but preserving the extracellular matrix. The pulses do not affect sensitive structures including neurovascular bundles, major vasculature and ductal systems preserving their function. It may address prostate regions implicated in prostate cancer without damaging vital structures, reducing side effects.
Osteosarcoma is the most common tumour of bone. Recent success in targeting immune checkpoint blockers such as Programmed death-1 (PD-1) in genomically complex tumours suggests that osteosarcomas may be amenable to such strategies. We will characterise the role of the PD-1 pathway in osteosarcoma development and growth. Using preclinical mouse models we will investigate the biology of the PD-1 pathway and study its potential as a therapeutic target in advanced and resectable osteosarcoma.
Use of antibodies for cancer therapy, where a protein is made in the laboratory to recognize and act on cancer cells that have a target antigen, has emerged as an important therapeutic area in oncology. The lewis-y (Ley) antigen is found on more than 70% of epithelial cancers and the A33 antigen is found on colon cancers. We have developed antibodies against Ley (hu3S193) and A33 (huA33) which can target cancer cells. We aim to develop optimal cancer cell killing by our antibodies.
Nanomedicines Immunotargeting: Hitting The Target Or Lost In Translation ?

Summary
Nanomedicines are some of the most exciting novel approaches to improving the way we detect, manage and treat cancers. This cross-disciplinary project aims to provide a rigorous understanding of how nanomedicines penetrate solid tumour tissues. To validate in vitro tumour model developed in the project, in vivo studies will be carried out in a mice model. The penetration and distribution of nanomedicines inside tumour tissues after intravenous administration will be determined.
Microtubule Cytoskeleton In Tumourigenesis And Metastasis

Summary
Over one million cases of lung cancer are diagnosed each year worldwide, making this the leading cause of cancer death. Advanced non-small cell lung cancer (NSCLC) accounts for more than 80% of lung cancer cases. We have identified a protein called ?III-tubulin that is often highly expressed in aggressive and drug resistant NSCLC, and is involved in tumour formation. We will examine how ?III-tubulin is working and identify ways to target this protein to stop tumour growth.
Improving Synthetic Methodology To Prepare Pre-clinical Analogues Of Human Insulin

Funding Amount

Summary
The glucose regulatory hormone, insulin, remains the only treatment for type I diabetes and up to 30% of type II diabetes, both of which are among the world’s fastest growing chronic diseases today. Because insulin, if taken orally, would be broken down quickly, it has usually been given by injection. This project will develop novel chemical methods for the efficient preparation of novel insulin therapeutics with improved stability and oral bioavailability for prolonged treatment of patients.
Improving the function of GABA-A receptors is a key property of several classes of clinically important drugs including benzodiazepines and many anticonvulsants. However, the binding sites and molecular mechanisms of these drugs remain poorly understood. Using compounds similar to those in green tea, we will determine the molecular mechanism of these drugs. This understanding will lead to the development of better drugs for treatment of anxiety, depression, epilepsy, insomnia & schizophrenia.
Development Of Selective Melanocortin Receptor Agonists And Antagonists

Funding Amount

Summary
Human melanocortin receptors play a key role in a variety of physiological processes ranging from energy regulation, skin pigmentation and regulation of food intake. This project aims to generate novel peptide based molecules that will selectively interact with different melanocortin receptors to better understand their pharmacology thereby opening the potential for future drug development for obesity, stroke or inflammatory skin disorders.
