Molecular Mechanisms of Hormone-Induced Cell Proliferation Research in my laboratory focuses on the cellular and molecular mechanisms of hormone-induced cell proliferation in reproductive organs. The gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH), are thought to provide the main stimuli for steroidogenic and proliferative activity in gonadal cells, whereas steroids themselves are thought to be the primary stimuli for proliferation in most other reproductive organs. Recent evidence suggests that a variety of growth factors and other peptides either mediate or modulate the actions of these hormones. Our investigations are directed toward identifying factors involved in regulating proliferative and activity in prostate, uterus, and ovary, then defining the molecular pathways through which these factors act. Current studies focus on two specific areas: 1. Molecular mechanisms regulating cell proliferation in the prostate. These studies include projects on regulation of cyclin production, characterization and regulation of cyclin-dependent kinase activity, identification of cyclin-dependent kinase targets, and identification of defects in normal regulatory processes resulting in prostate cancer. 2. The actions of leukocyte secretory products (cytokines) on steroidogenic activity in ovarian cells. These studies include projects on receptor interactions, signal transduction pathways, and characterization of novel cytokines in reproductive tissues.
