Brief description A continual supply of oxygen is essential for normal functioning of the human body. When oxygen levels become limiting, the body attempts to rectify the situation by increasing the number of oxygen carrying red blood cells and promoting development of new blood vessels to increase the blood supply to tissues. Cells also adapt by altering their internal biochemistry and metabolism to decrease energy needs. These changes are the result of a genetic reprogramming within the cells. A major question is how the cells sense they are in a low oxygen environment and by what mechanisms they initiate genetic reprogramming. We are studying two proteins which have the ability to alter activity of genes when cells are stressed by hypoxia (low oxygen), and seek to discover how the proteins switch from latent forms to active forms in response to hypoxia. A greater understanding of the molecular mechanisms involved in the cellular hypoxic response is important to the development of new therapeutics for disease states involving disrupted oxygen flow (eg heart attack and stroke). Drugs which would block the hypoxic induced development of blood vessels could also be extremely beneficial in cancer treatment, as blocking blood supply to growing tumours can result in their starvation and shrinkage.
