A new study in an animal model of aging indicates a potential reason for why women who have early menopause or other genetic conditions affecting the reproductive system are more prone to develop cardiovascular disease, diabetes, and dementia.
The new study, led by researchers from the University of Pittsburgh and UPMC and published in the journal Aging Cell, found that disrupting a process called meiosis in C. elegans reproductive cells caused a decline in the worms’ health and triggered an accelerated aging gene signature similar to that of aging humans.
“This study is exciting because it’s the first direct evidence that manipulating the health of reproductive cells leads to premature aging and a decline in healthspan,” said senior author Arjumand Ghazi, Ph.D., associate professor of pediatrics, developmental biology, and cell biology and physiology at Pitt and UPMC Children’s Hospital of Pittsburgh. “The implications of this finding are profound: It suggests that the status of the reproductive system is important not simply to produce children, but also for overall health.”
