About:
My research interests center on inflammation, the response to injury and infection, and my goals are to elucidate the molecular mechanisms which regulate activity of an inflammatory mediator called leukotriene B 4 (LTB 4). This molecule is a chemoattractant for white blood cells such as neutrophils, and is implicated as a pathological mediator in diseases which include ischemia-reperfusion injury, glomerulonephritis, and asthma. The gene designated CYP4F3 (cytochrome P450 4F3) encodes an enzyme which inactivates LTB 4, and I am investigating the possibility that CYP4F3 functions to attenuate LTB 4 responses and limit inflammatory disease.
My research work is primarily at a molecular level and involves cell and molecular biology techniques. The current focus of this work involves an analysis of CYP4F3 gene expression, which combines tissue-specific promoters and alternative splicing. My specific objectives are to identify regulatory sites in the gene that control CYP4F3 transcription and exon selection. At a broader level, I am interested in the functions of a group of cytochrome P450s which form a 4F multigene family. In addition, I maintain a collaboration with the Massachusetts General Hospital where we are investigating the role of CYP4F3 in mouse models of inflammatory disease.
