William M. Wood, Ph.D.

Associate Professor of Medicine

Dr. Wood received a Ph.D. in Biochemistry from the University of Glasgow in Scotland. Following post-doctoral studies at the Universities of Illinois and Pittsburgh, he joined the faculty of the University of Colorado School of Medicine in 1985. He is now an Associate Professor and, in 1996, received the Ph.D. Research and Teaching Award from the Department of Medicine. Dr. Wood's research interests lie in the area of pituitary gene expression and regulation and thyroid cancer. He has worked on the molecular determinants governing thyrotrope expression and thyroid hormone (TH) regulation of the thyrotropin subunit genes. He has also been defining the role of an upstream regulatory region in the pituitary cell type dependent activation and repression of the alpha subunit gene. In related studies he has been investigating the regulation of pituitary cell growth by TH. These studies have led to the cloning and characterization of the promoter region of the pituitary-specific beta-2 isoform of the TH receptors (TRs). Other research endeavors involve the role of somatostatin receptor (sst) subtypes, specifically sst 5 and 1, in thyrotrope growth arrest by TH and the interface of TRs via sst5 with the cell cycle apparatus. More recently he has been examining the association of peroxisome prolilerator-activated receptor gamma (PPARg) with more aggressive thyroid cancer and has shown that its depletion slows the growth of thyroid tumors in an orthotopic mouse model of thyroid cancer.
