Summary
The myeloproliferative disorders are diseases in which abnormal blood cell development leads to a risk of stroke, thrombosis, hemorrhage and leukemia. Remarkably, three of these disorders are caused by an error in a single enzyme that makes it over active. The enzyme, JAK2, controls how cells respond to hormone-like messengers called cytokines. We are investigating a cellular pathway that inhibits this enzyme in order to understand the progression and potential treatment of the disorders.

Summary
The PI3K/AKT signalling pathway drives many cancers and until recently was thought to do so by preventing cancer cell death. We have shown this pathway also regulates the synthesis of ribosomes, the cellular “factories” that make protein and by interfering with PI3K/AKT regulated ribosome synthesis, can kill cancer cells. We aim to establish the mechanisms underlying this regulation of ribosome synthesis and to test the hypothesis that ribosome biogenesis is a novel target for cancer treatment.

Summary
Cytokines are hormones that regulate blood cell production and function. The research proposed in this application focuses on the biological roles and biochemical mechanisms of action of an important family of proteins that control the actions of cytokines, thereby allowing their beneficial effects in coordinating oxygen transport, blood clotting and responses to infection, while preventing the harmful effects of excess responses, such as myeloproliferative diseases or autoimmunity.
