Biographical Information
James Janik is a neuroendocrinologist whose primary interest is regulatory control of anterior pituitary hormone secretions. He is particularly interested in the neuroregulatory role played by the Endogenous Opioid Peptides and the recently discovered, novel neuropeptide, Orphanin FQ. Using the rat and knock-out mouse as their primary research models, students in his laboratory investigate mechanisms of hormonal control under several different physiological conditions at both the in vivo and in vitro levels. A major thrust of the work is determining the impact of gender and reproductive state, in particular lactation, on hormonal control mechanisms.
