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.
Investigate Novel Functional Roles For PI 3-kinases In Platelets.

Summary
Platelets are small blood cells which have a well defined role in blood clotting. There is a growing body of evidence that platelets play an important role in a broad range of inflammatory diseases, and we have identified a key role for the platelet PI3K enzyme in controlling the pro-inflammatory function of platelets. This grant will examine the importance of PI3K in health and disease, and examine the potential therapeutic benefits of inhibiting platelet PI3K.

Summary
Platelets are small cells in the blood stream that play an important role in preventing excessive blood loss at sites of tissue injury by sticking together and forming a haemostatic plug. Excessive platelet clumping in diseased blood vessels can lead to blockages and cause thrombotic diseases such as heart attack and stroke, two of the biggest killers of humans in the western world. In this proposal, we will seek to understand how immunoreceptors expressed on the surface of platelets modulate th ....Platelets are small cells in the blood stream that play an important role in preventing excessive blood loss at sites of tissue injury by sticking together and forming a haemostatic plug. Excessive platelet clumping in diseased blood vessels can lead to blockages and cause thrombotic diseases such as heart attack and stroke, two of the biggest killers of humans in the western world. In this proposal, we will seek to understand how immunoreceptors expressed on the surface of platelets modulate the function of platelet collagen interactions involving collagen GPVI receptor, the low affinity IgG receptor, FcgammaRIIa and the major platelet integrin, integrin alphaIIbbeta3. The aims of this work will define the role of these receptors in platelet aggregation both in cell-based assays and in mouse models of thrombosis. This work could lead to new strategies for therapeutic management of thrombotic disorders.Read moreRead less
Zbtb11 is a druggable protein that is mis-expressed in blood cancers - second biggest cause of cancer death in Australia - and liver cancer, third leading cause of death from cancer worldwide. We have found that it interacts with 2 other proteins with potential roles in these diseases. Our studies examine the nature of these Zbtb11-partner interactions and their particular consequences for blood disorders. Zbtb11 contributions to disease development will be a target for novel disease therapy.
