Acute Lymphoblastic Leukemia And The Bone Marrow Microenvironment

Summary
This research aims to identify new drugs for the treatment of childhood and adult acute lymphoblastic leukemia (ALL). We have identified drugs that interfere with interactions between the bone marrow and leukemic cells and hypothesise that these will increase the potency of currently used chemotherapy. We will test these agents in animal models of human leukemia. By analysing the effects of these new drugs we will also understand how we can further improve treatments.
The Role Of Cell Cycle Control In Haemopoietic Stem Cell Fate Decisions.

Summary
My research has focused on understanding how the process of cell division can result in different outcomes for adult blood stem cells. I am interested in determining the role of bone and blood vessels in the regulation of blood stem cells and in the development of blood diseases (myeloprolifertive disease). I will also determine the effects of changing the cell cycle with drugs to improve transplantation of blood stem cells.

Summary
Neutrophils are the white blood cells that protect against infection. A surprising protective neutrophil behaviour was recently described – neutrophils can pack up their internal DNA and antimicrobial enzymes and explosively release them into their surrounds, forming a “Neutrophil Extracellular Trap” (NET). This project uses zebrafish built have fluorescent neutrophils to study NET release in living animals. We will learn how NETs control infection and what goes wrong when NETs cause disease.
A Virtual Map Of Haematopoiesis Using Cellular Barcoding

Summary
We have different types of infection-fighting white blood - the soliders of the immune system. They can all grow from a single stem cell like a seed grows into a tree. So, by understanding this complex process, new and better therapies for cancer, organ transplantation and infectious disease are constantly emerging. I aim to use a cutting-edge technology called ‘cellular barcoding’ to answer some of the age-old questions about how stem cells grow into white blood cells.
Microenvironmental Regulation Of Blood Cells By Retinoic Acid Receptor Gamma.

Summary
Vitamin A deficiency causes profound effects in humans, with anaemia and an inability to fight infection being consequences of vitamin A deficiency on blood cells. We have evidence that these effects of vitamin A deficiency occur via one of the receptors for vitamin A. Furthermore, these effects are due to changes in the non-blood cells that help to make blood cells. By understanding how this occurs we may identify better treatments for patients with impaired immune systems.
Studies Of Myeloid Leukaemogenesis In The Zebrafish

Summary
This project aims to investigate the causes of white blood cell cancer, or leukaemia, at the molecular level, using a novel approach in zebrafish. Zebrafish provide a powerful experimental model for developmental genetics, largely due to the visual and technical accessibility of embryos for experimentation. We plan to introduce a fluorescent molecular tag into the white blood cells in order to directly visualise them. We will then predispose these fish to leukaemia and screen for mutants with en ....This project aims to investigate the causes of white blood cell cancer, or leukaemia, at the molecular level, using a novel approach in zebrafish. Zebrafish provide a powerful experimental model for developmental genetics, largely due to the visual and technical accessibility of embryos for experimentation. We plan to introduce a fluorescent molecular tag into the white blood cells in order to directly visualise them. We will then predispose these fish to leukaemia and screen for mutants with enhanced or suppressed leukaemia. We anticipate that the mutants will allow new genes involved in the development of leukaemia to be identified.Read moreRead less
Epigenetic Regulation Of Self Renewal And Lineage Commitment In Haematopoiesis

Summary
The process by which all our mature blood cells are produced and sustained remains largely unknown. Underpinning the cell fate decisions made through blood cell development is the tightly regulated expression of key genes and proteins that subsequently direct the process of blood cell differentiation. This project will aim study and uncover the molecular mechanisms that coordinate the key gene expression programs that lead to normal blood cell development.
Defining The Role Of RNA Editing In Erythropoiesis

Summary
We are seeking to understand how red blood cells are produced. We have identified that a process called RNA editing may be important in the regulating the production of red blood cells.
