Signal Transduction The department is rich in research devoted to the analysis of signal transduction pathways and their role in normal physiological processes and disease. These include studies into the basic mechanisms of signaling by oxidizing and free radical inflammatory mediators, nitric oxide, steroids, parathyroid hormone, neurotransmitters, hypothalamic hormones, and rhodopsin. Various cell biological, forward and reverse genetic, molecular biological and biophysical approaches are used to dissect the molecular mechanisms utilized by intracellular mediators of signal transduction including cell surface receptors, nuclear receptors, caveolin, protein kinases, protein phosphatases and lipid kinases.
