NIEHS scientists consider the future of mammalian reproduction
By Shannon Whirledge
Twelve NIEHS scientists set out for Colby Sawyer College in New London, New Hampshire, Aug. 10-15 for the inaugural Gordon Research Conference on Mammalian Reproduction. The organizing committee acknowledged the outstanding work of NIEHS scientists, through invited talks and travel awards (see sidebar). The meeting embraced the heritage of the Gordon conferences, by featuring unpublished, up-to-the-minute findings and presentations by young researchers, including three NIEHS trainees.
If exciting new data is a commodity, then the Gordon Research Conferences have cornered the market. With an emphasis on novel work, this year’s Mammalian Reproduction conference filled five days with seminars, short talks, and poster sessions, and plenty of time for interacting with colleagues. The conferences have a long-standing history of hosting high-quality meetings that bring young scientists together to discuss current research.
NIEHS trainees recognize this as an advantage to attending the Gordon conferences. “These conferences are great for trainees to interact with senior scientists in the field,” said Wipawee (Joy) Winuthayanon, Ph.D., a research fellow in the Receptor Biology Group. “The Mammalian Reproduction conference is small and interactive, with a lot of opportunities for social interactions with senior researchers,” said Erica Ungewitter, Ph.D., Intramural Research Training Award fellow in the Reproductive Developmental Biology Group.
Sylvia Hewitt, senior biologist in the Receptor Biology Group, spoke of the unparalleled access to preeminent scientists. “It allows us to get input on projects that are under development from experts in the field, including learning techniques that will advance our research,” she said.
Clinical applications of NIEHS discoveries
The theme of this year’s conference was “Translating Basic Science Into Clinical Applications.” Sessions focused on innovative basic research findings that have implications for new clinical applications. The various mechanisms by which environmental compounds can disrupt normal reproductive functions are of considerable interest to NIEHS researchers and the entire field of reproductive biology.
Humphrey Yao, Ph.D., lead researcher of the Reproductive Developmental Biology Group, was featured during the opening session. His talk focused on understanding the early events that lead to sex determination. Yao described data from a project he called his pet project, which uses genetic approaches to identify novel factors controlling development. Such insights can lead to a better understanding of the origins of infertility, according to Yao.
Carmen Williams, M.D., Ph.D., lead researcher of the Reproductive Medicine Group, spoke on “Environmental Effects on Reproductive Functions.” She described how timing and the type of early-life exposure to endocrine disruptors can alter the development of disease in adults. The effects of diethylstilbestrol have persisted across generations and have resulted in infertility. Williams illustrated gene-specific epigenetic reprogramming that may be responsible for the transgenerational inheritance.
