Research
The laboratory is carrying out research on the molecular mechanisms responsible for human diseases. The approach is to use molecular, genomic and cellular approaches to investigate basic aspects of the pathogenesis of atherosclerosis. A major focus is on molecular mechanisms of cellular cholesterol efflux, mediated by the interaction of extracellular apoA-I with the lipid transporter ABCA1. We are carrying out studies on the transcriptional regulation of ABCA1 gene expression, and regulation of the degradation of ABCA1 protein. This has led to the elucidation of a class of transcription factors (LXRs) that co-ordinately regulate cellular cholesterol efflux and reverse cholesterol transport.
