Summary
We aim to use the animal model system, the vinegar fly, to investigate mechanism for cancer initiation. The fly has been studied for over 90 years and has proved an excellent genetic model for understanding the complex processes leading to abnormal cell growth, which is associated with the early stages of human cancer. The high level of conservation between fly genes and human cancer genes means these studies will provide novel insights into the genetic mechanisms underlying tumour formation.

Summary
A fundamental question in medical biology revolves around how cells respond to the demands to grow and produce proteins, particularly in the setting of the rapid growth of cancer cells. One of the important facets of cellular growth is the production of new proteins needed for all areas of cell life. It is well known that cellular growth involves the production of proteins and this in turn requires the transcription or duplication of ribosomal RNAs (rRNAs). The control of rRNA synthesis, however ....A fundamental question in medical biology revolves around how cells respond to the demands to grow and produce proteins, particularly in the setting of the rapid growth of cancer cells. One of the important facets of cellular growth is the production of new proteins needed for all areas of cell life. It is well known that cellular growth involves the production of proteins and this in turn requires the transcription or duplication of ribosomal RNAs (rRNAs). The control of rRNA synthesis, however, is not well understood. We have identified a novel process to link a cancer causing gene c-MYC to the control of protein production in cells through regulation of rRNA synthesis. Our experiments will examine the hypothesis that c-MYC directly affects the production of rRNA . Finally we will test the link between the ability of c-MYC to cause malignant growth of cells and its role in increasing synthesis of rRNA. These findings may lay the basis for new treatments for disorders of regulated cell growth such as cancer.Read moreRead less
