Study Of C-KIT Mutations In Familial Gastrointestinal Stromal Tumours, Melanoma And A Novel Form Of Waardenburg Syndrome

Summary
The primary aim of this research project is to study mutations in a cancer causing gene called c-KIT. We seek to identify tumour characteristics which are predictive for the presence of particular types of c-KIT mutations in melanomas and gastrointestinal stromal tumours. The detection of tumours harbouring these mutations will help in the treatment of cancer sufferers because this group of patients have been shown to respond very well to a class of drugs known as tyrosine kinase inhibitors.
A Comprehensive Analysis Of Myb Target Genes Involved In Myelopoiesis And Myeloid Transformation

Summary
The MYB gene is essential for both normal blood cell formation and the growth of leukaemia cells. It acts by switching other genes (target genes) on and off. This project aims to advance our understanding of how MYB functions, by carrying out a comprehensive search for MYB target genes. In particular it will focus on target genes that help explain MYB's ability to control cellular growth and maturation. Some of these target genes may provide leads for future anti-cancer drug development.

Summary
Growth factors acting on cell surface receptors activate multiple intracellular signalling pathways that regulate cellular growth and function. Mutations in the genes that code for these receptors or their downstream signalling pathways contribute to many human cancers. The contributions of different signalling pathways linked to these receptors to the various cellular responses (growth, maturation, functional activation) are not understood.

Mutations in the genes that code for these receptors or their downstream signalling pathways contribute to many human cancers. The contributions of different signalling pathways linked to these receptors to the various cellular responses (growth, maturation, functional activation) are not understood. In this project we aim to use cell and molecular biology approaches to determine the role of different signalling pathways in cellular responses mediated by the growth factor receptor c-Kit. The c-Kit receptor has essential functions in blood cell development, skin and hair pigmentation, gut function and the reproductive system. It is also essential for the development and function of mast cells which trigger allergic responses such as asthma and eczema. Mutant forms of the receptor have been identified in certain leukaemias and colon cancers. Many new drugs that target specific intracellular signalling pathways have recently been developed and are beginning to be evaluated in clinical trials. Better understanding of how individual pathways contribute to the function of c-Kit and other receptors is essential for optimal use of these new drugs. For example, it may enable the choice of drugs to block c-Kit dependent cancer cell growth or allergic reactions without affecting the growth of normal blood cells.Read moreRead less
