Kathy is a member of the Lifestyle research group and her recent research examines the interaction of dietary lipoproteins with cells of the vasculature and liver.
Biography
Kathy Botham graduated with a BSc(Hons) in Biochemistry from the University of Liverpool in 1969, and she obtained a PhD in Biochemistry from the same institution in 1972. After a period of three years in the United States working with Hector DeLuca on vitamin D metabolism, she returned to the UK to join the sterol metabolism group headed by Professor George Boyd at the University of Edinburgh.
In 1986, she joined the Royal Veterinary College as a Lecturer, and was appointed to a Chair in Biochemistry in August 2007. Kathy was awarded a DSc by the University of Liverpool in 2002 for her contribution to research in the field of cholesterol and lipoprotein metabolism. Her current research centres on the role of dietary fats and other factors in the development of atherosclerosis.
Research
Kathy is a memebr of the Lifestyle research group and her main research interest is lipid and lipoprotein metabolism. In particular Kathy is interested in the effects of dietary lipids on the initiation and development of atherosclerosis. This includes interaction of lipoproteins from the diet with cells of the vasculature; including macrophages, monocytes and endothelial cells and also with the liver.
Current projects focus on the influence of chylomicron remnants on monocyte activation, macrophage foam cell formation and endothelial cell function, and on the effects of oxidation of the lipoprotein particles. Kathy is currently collaborating with Istituto Superiore di Sanitá; in Rome, University of the Basque Country in Bilbao and Instituto de la Grasa in Seville. Kathy also collaborates within the RVC with Drs Charlotte Lawson & Caroline Wheeler-Jones on lipoprotein-cell interactions.
Teaching
Kathy teaches on the BVetMed Year 1 Alimentary module, the BVetMed Year 2 Principles of Science module and the BSc Bioveterinary Science Year 1 Gastrointestinal Tract and Regulation & control modules. She also plays a minor teaching role on the Graduate & Transfer and Gateway courses. In addition she acts as a supervisor on 2nd and 3rd year BSc Bioveterinary Science research projects.
