Dr. Anthony J. Zeleznik received his PhD in Physiology from the University of Michigan in 1975. His doctoral work, conducted under the direction of Dr. A. Rees Midgley, Jr., was the first to document that a principal action of follicle stimulating hormone in the ovary was to induce LH receptors on granulosa cells, an action that enables the follicle to ovulate and luteinize in response to LH. Following the completion of postdoctoral work under the direction of Drs. Jesse Roth and Griff Ross at the National Institutes of Health, Dr. Zeleznik joined the Department of Physiology at the University of Pittsburgh in 1978, where he began a systematic investigation on the physiological and cellular control mechanisms that govern the menstrual cycle in higher primates. Dr. Zeleznik served on the Editorial Boards of Endocrinology, Biology of Reproduction, The American Journal of Physiology and the Journal of Endocrinology, as well as having been appointed as a member of three NIH Study Sections.
