Summary
Development of blood cells is controlled by specific molecules called transcription factors. Transcription factors are important in developing mature white cells, red cells and platelets from blood stem cells. We have discovered that a transcription factor, Erg, is important in control of blood stem cells and blood cell development as well as being implicated in human cancers, including acute leukaemia. This project will characterise how this molecule is involved in these specific processes.
We will investigate how the master control gene, Kruppel-like factor 1, orchestrates production of red blood cells. We will use genetic and cell biology approaches to determine exactly how this factor interprets the genome blueprint in a cell specific manner. We will also determine how mutations in KLF1 cause human diseases such as congenital dyserythropoietic anemia and hereditary persistence of fetal haemoglobin. This has implications for reactivation of HbF in adults with sickle cell disease.

Summary
Lymphatic vessels control tissue fluid drainage, inflammatory processes and cancer progression. We have used genetic approaches to discover an unexpected role for a family of factors (transcription factors) that regulate new lymphatic vessel formation. This project will investigate this biological function of these genes in detail in vascular formation. The project aims to generate important knowledge for vascular biology, vascular pathologies, cancer spread and future therapeutics.
The Role Of Ikaros In Establishing Regulatory Networks For Lymphocyte Development

Summary
Ikaros is a protein that regulates gene expression during development of lymphocytes from blood stem cells. Ikaros has a profound importance in normal and malignant lymphocyte development, but we still do not know how it controls these processes. The aim of my study is to identify genes regulated by Ikaros and the molecular mechanisms of their regulation. This study will contribute to understanding of the regulatory network controlling the development and function of lymphocytes.
