Summary
We have found that some tumours use a previously unknown strategy for evading the normal limits on cellular proliferation. We will analyse the molecular details of this mechanism in order to (i) understand how it works, (ii) devise a diagnostic test, and (iii) lay the foundations for developing treatments that specifically target this type of cancer.

Summary
Neuroblastoma is one of the most common cancers in children. We have found that a genetic regulator, called microRNA, can limit the ability of neuroblastoma cells to invade surrounding tissues and metastasise. We aim use the microRNAs to find new therapeutic targets that may work in combination with existing treatments, reducing the short term toxicity and long term deleterious effects of current treatments.

Summary
Neuroblastoma chemotherapy often only works temporarily because a small number of tumour cells can resist drugs and eventually regrow as a new tumour. These resistant cells resemble the very first cells that turn into a cancer cell at tumour initiation. We have used single cell technology to uncover genetic markers of tumour initiating cells. In this project we will determine how these marker genes cause tumour initiation and develop therapies that target them in drug resistant neuroblastoma.
Cancer remains a major cause of morbidity and mortality in the developed & developing world. Underpinning the causes of cancer are genetic and cellular changes in key structural proteins that control cell growth and movement. My research aims to discover key links in the regulation of these proteins that lead to tumour formation, metastasis and drug resistance. My goal is to use this knowledge to develop effective and less toxic treatment strategies to target difficult-to-treat cancers.
Neuroblastoma (NB) is a common cancer in children, and one of the hardest to cure. Some mature into a benign tumour without needing any treatment, others are aggressive and require intensive treatment, and some regrow despite all treatment. It is often difficult to predict accurately how NBs will behave. We will study the two ways NBs can undergo unlimited growth, to determine whether this predicts tumour behavior, and therefore what treatment is needed.
