Summary
The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal me ....The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal menstrual cycle, and for the normal growth and development of the placenta and a new baby. The processes by which these new blood vessels form and the factors contributing to the maintenance of their structure are incompletely understood. However, it is known that the interaction of cells and the surrounding extracellular matrix is critical for normal cell function and in particular for new blood vessel formation. Studies in this project will seek to define a relationship between some of the factors which regulate blood clotting, and those that regulate turnover of the extracellular matrix and new blood vessel formation. In particular, how blood clotting factors may be invovled in the regulation of the extracellular matrix will be studied in a rapidly developing tissue, the mouse placenta. The role of blood clotting factors in regulation of new blood vessel formation into an artificial avascular tissue will also be examined. These studies will employ some of the new genetic techniques to understand new roles for proteins which have been traditionally thought to act in only one way. This research has the potential to provide new insights into how blood vessels are formed and are subsequently maintained. This increased understanding will provide the knowledge required for the development of new therapeutic strategies to correct the process when it goes wrong, is unwanted or underdeveloped in human disease.Read moreRead less
Factor XII-dependent Thrombosis And Platelet Glycoprotein Ib
Funder

Funding Amount
$336,767.00
Summary
We will determine the value of targeting the interaction between a receptor unique to platelets, glycoprotein Ib, and two factors (XI and XII) in plasma involved in blood clotting, as a novel strategy to prevent clots that lead to heart attack-stroke. Our study is at the basic research-clinical interface and has the potential to improve our understanding of both bleeding in patients with Factor XI-XII defects and prevention of dangerous levels of clotting without affecting normal vessel repair.
A Randomised Controlled Trial Of Factor Replacement Therapy In Snake Bite Coagulopathy
Funder
National Health and Medical Research Council
Funding Amount
$715,730.00
Summary
This proposal seeks funding to undertake a controlled trial of clotting factor replacement in snake bite coagulopathy after the administration of a neutralising dose of antivenom. The aim is to determine if factor replacement will result in a rapid return of clotting function in patients and therefore reduce the potential risk of major bleeding. This study will have international implications because globally snakebite coagulopathy is a major cause of morbidity and death like in Australia.
