Summary
Regulation of normal colon biology and activation of genes involved colon cancer The c-myb gene is essential for the normal biology of the blood system and the colon. This gene is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. There is a large body of evidence that supports the role of c-myb in the regulation of the blood system.

This gene is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. There is a large body of evidence that supports the role of c-myb in the regulation of the blood system. We believe that the rules that govern the production of the huge number of cells needed to have a healthy blood system are similar if not identical to the rules used by the colon. This is because the colon also produces a massive number of cells each with special tasks and a defined life span of a few days. It is this rapid expansion of cell numbers and the programmed short life span of cells that necessitates multiple controls and very tight regulation. Furthermore if this process is hijacked by genetic changes that undermine these controls then there are numerous opportunities to initiate and potentiate malignant change or cancer. This project examines the role of the same genes in two contexts. Firstly when the genes are expressed at normal, highly regulated levels associated with the normal biology of the colon. The second context is when these genes are permitted to be over-expressed and thus drive processes for longer or in inappropriate situations leading to malignant growth.Read moreRead less
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.
