Brief description Cancer cells usually exhibit the loss of control of normal cell functions. This involves the increase of proteins which promote growth and cell division and the decrease in proteins which inhibit growth and cell division. Loss of function may also occur in proteins that are normally involved in killing the cell when growth becomes uncontrolled. Many of these proteins interact with one another and in so doing establish pathways and networks of control which must be perturbed and overridden in the cancer cell. Sometimes this is because the role of the protein is altered in the cancer cell compared to what it normally is in a normal cell. The main aim of this study is to understand the role that is played by a set of proteins that are coded by a single gene. This gene (which we refer to as the FOR gene) spans a region of the human genome which is sensitive to a particular type of mutation. This mutation takes place early in tumour development and therefore we believe that it has important role to play in determining the fate of the cell - helping to cause it to become a tumour cell. We will find out which other proteins in the cell the FOR proteins interact with. Where these proteins are known then this will help determine the pathways in the cell in which the FOR proteins participate. In another approach we will establish animal models (in mice and flies) of mutations in the FOR genes of these species. The transgenic mice will help us find out whether the mutations that we have observed in the FOR gene in various human cancers cause increased sensitivity to mutagens and in so doing aid in transforming normal cells into cancer cells. The transgenic flies will help us identify the metabolic pathways in which the FOR proteins participate. These studies will help understand the roles of the FOR proteins and their significance in cancer.
