Thursday, February 11, 2021
12:00 pm - 1:15 pm
Jason E. Podrabsky, PhD, Portland State University
Integrated Toxicology & Environmental Health Seminar Series

Annual killifishes survive in temporary aquatic environments by producing drought-tolerant embryos that survive in the dry soil by entering up to 3 stages of development dormancy (diapause) during development. Each stage of diapause is responsive to different environmental cues. In this talk, Dr. Podrabsky will focus on the role of light and heat in regulating diapause through vitamin D signaling, and how vitamin D signaling alters DNA methylation patterns as embryos exit from metabolic dormancy. The talk will explore, in a broader sense, the role of environmental signaling in the control of development.
