Exploiting hypoxia and DNA repair defects for treatment of triple-negative breast cancer.
An aggressive and prevalent form of breast cancer, known as triple-negative breast cancer (TNBC), is associated with poor prognosis and limited treatment options. Two pervasive features of TNBC are hypoxia (low oxygen) within tumour tissue and defects in error-free DNA repair machinery. A panel of hypoxia-activated prodrugs (HAP) developed at the Auckland Cancer Society Research Centre simultaneously exploit tumour hypoxia and DNA repair deficiency to selectively kill cancer cells. This project will explore the potential use of HAP as a novel treatment for TNBC, with the objective of working toward clinical trials for these agents in human cancer patients.
Isoform-specific targets of Akt in breast cancer metastasis
The aggressive behaviour of malignant breast cancers is determined by a complex array of signalling pathways that regulate cell growth, survival and invasive migration. One of the most frequently deregulated pathways in breast cancer involves a protein called Akt. This research aims to explore the mechanisms by which different members of the Akt family can either promote or inhibit the spread of breast cancer cells to distant tissues. This research will permit the identification of critical downstream mediators of the Akt signalling pathway thereby enabling the development of targeted therapies for the treatment of breast cancer.
Advanced clinical training in musculoskeletal oncology
Andrew Graydon, a NZ trained Orthopaedic Surgeon is undertaking subspecialty training and experience in Sarcoma treatment at Vancouver General and BC Children's Hospitals in Vancouver, Canada. Sarcomas are rare but often lethal tumours, that arise in the bones and joints of both adults and children. Treatment of these tumours is highly specialised, with many innovative new techniques improving survival and quality of life following treatment. Following the fellowship Dr Graydon will return to work at Starship Children's Hospital in Auckland, where he will join the Paediatric Oncology team introducing some of these new techniques in treating children from around NZ.

MicroRNAs and YB-1; a dangerous liason in cancer biology?
YB-1 is a protein found in breast tumours that promotes their growth and high levels are linked with poor outcomes for patients. YB-1 binds to RNAs, the product of our genes. microRNAs are a small type of RNA that have recently been associated with the development and progression of cancers. We would like to investigate whether YB-1 controls tumour growth through interaction with these microRNAs, affecting their function. We hope to show an interaction between these molecules that will help in the development of novel therapies or diagnostic tests for breast cancer.
A Phase III trial of adjuvant chemotherapy following chemoradiation as primary treatment for locally advanced cervical cancer compared to chemoradiation alone: THE OUTBACK TRIAL
This study will be comparing the treatment of patients with locally advanced cervical cancer. Half of the patients enrolled in the study will receive the standard pelvis radiation and chemotherapy combination and half will receive the standard treatment and an additional four courses of 3-weekly chemotherapy. The study is aiming to determine whether there is an improvement in survival from additional chemotherapy and whether the side effects and quality of life on the study are acceptable so that this may become the standard of cervical cancer care in the future.
Anti-cancer drugs generally target processes inside cancer cells that allow them to continue to divide. Microtubules, which form the framework for much of the cell division machinery, have proven to be a clinically important drug target. Many microtubule-targeting agents have their origins in natural products; however the original natural products are not optimised for human cancer therapy. Consequently, it is important to make and evaluate variants which increase our knowledge of the way the compound works and improve its anti-cancer function. This project will make analogues of the natural product zampanolide, a microtubule stabilising agent isolated from marine sponges.
Oestrogen dependent regulation of gene expression by cohesin in breast cancer
Every year, 2300 New Zealand women develop breast cancer. About 70% of breast cancers are positive for oestrogen receptor (ERa). ERa-positive breast cancers are treated with anti-oestrogens such as tamoxifen, but drug resistance is common. Cohesin is a protein involved in both cell division and gene expression. Importantly, cohesin controls the oestrogen-responsive cancer-causing gene, MYC. Too much MYC causes resistance to anti-oestrogen therapy, and targeting cohesin may overcome this resistance. We will determine how cohesin contributes to the cancer role of oestrogen and identify cancer genes controlled by both ERaand cohesin. Our results may lead to new breast cancer therapies.
Validation of AKR1C3 as a therapeutic target in castration-resistant prostate cancer
In 2007, prostate cancer was the most commonly registered cancer in NZ. In many cases, treatment is limited to androgen deprivation therapy; however, tumours usually develop resistance by producing their own androgen supply. For prostate cancer treatment to be effective, new therapies are required to overcome this resistance. We have developed new chemotherapy drugs that inhibit an enzyme (AKR1C3) involved in androgen production to prevent androgen-dependent tumour progression. We plan to test these new drugs in cellular models of resistant prostate cancer to determine their effectiveness against tumour cell survival and to identify candidate drugs for clinical trials.
The Diet Intervention in Bladder Cancer Study (DIBS): A Pilot Trial of Diet Change for Superficial Bladder Cancer
Bladder cancer is common and often recurs, meaning that patients have to have checks at regular intervals for years on end. A potential means of decreasing the number of bladder cancer patients who recur or progress is diet change. Population studies strongly suggest that diets high in cruciferous vegetables, such as broccoli and related vegetables decreased the risk of bladder cancer. In this study we are trying intensive coaching by internet (using Skype) to see if this will increase patients' consumption of cruciferous vegetable.
3D Imaging of Tumour Hypoxia
The blood supply in tumours is chaotic and inefficient and this results in areas of low oxygen that lead to more aggressive tumours and are treatment resistant. This projects aims to develop a method to make three-dimensional images of low oxygen areas in tumours in relation to blood vessels at the microscopic level and that allows study of how the picture changes over time. This may help to understand how tumours behave and how they, and thus the patient, respond to therapy.
Development of a tool to predict lung function following radiotherapy for lung cancer
Lung cancer is mainly due to smoking and is the most common cause of cancer death in NZ. In many cases the patient cannot be cured by surgery or radiation, because the lungs have also been damaged by smoking, causing emphysema. The aim of this project is to develop a tool to predict whether individual patients with lung cancer will tolerate the radiation treatment necessary to cure the cancer without leaving the patient with insufficient breathing capacity. This tool, which has been developed in NZ, will be a world first and will be based on sophisticated computer modelling of individual patients.
The trehalose dimycolates as potent immunomodulators in cancer therapy
The immune system has a powerful role in the control of disease, yet often with cancer patients, the inherent immune response is not sufficient to control tumour growth. Macrophages are key immune cells that, on the one hand, are able to lead to tumour destruction, yet on the other hand, can also promote an increase in tumour burden. To convert the dysfunctional, tumour-promoting macrophages to ones that can be used to fight tumours, we are developing small molecules that will ‘switch' the macrophage to an activated state that will lead to tumour regression.
Using virus-like particles to fight cancer
The development of vaccines is a significant strategy in the war against cancer. This project aims to develop anticancer vaccines using harmless virus shells, termed virus-like particles (VLP) to deliver immunizing tumour peptides. The peptides will be derived from human papilloma virus (the causative agent of cervical cancer) and melanoma. Both of these cancers are a major health problem in New Zealand. We also intend to determine whether we can delay the progression of pre-existing cancers with this new VLP. VLP vaccines that work in mice will be tested on human cells to initiate translation of this work to the clinic.
