UNIVERSITY PARK, Pa. Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with decreased lifespan in humans; therefore, the team s findings may have implications for human longevity.
Human men have shorter telomeres than women, which may partly explain why they have shorter lifespans of about seven years, said Tracy Langkilde, professor and Verne M. Willaman dean of the Eberly College of Science. Our study shows that stress experienced by mothers during gestation could further shorten the telomeres, and theref ....

What led you to begin this research?
My laboratory has been studying mammalian metabolism and hypoxia for over three decades, working with human triathletes as well as dolphins, narwhals, lions, bears, and more. In trying to answer the question ‘How do marine mammals hold their breath for so long?’, we have found that tolerance to hypoxia varies markedly among animals. ....
