J. Kenyon Cynthia J. Kenyon made the groundbreaking
discovery that aging is a regulated, hormone controlled process –
which can therefore be manipulated. She has shown in the nematode C.
elegans that genes encoding components of an insulin/IGF-1 endocrine
signaling system govern the transcriptional control of antioxidant,
chaperone, metabolic and anti-bacterial genes. By manipulating this
system, C. Kenyon succeeded to extend the lifespan of C. elegans by
six fold. Biology of Aging thus may arrive at a turning point, and the
old dream of a long life in health may come closer to the realm of possibility.
Although these findings are as yet not applicable to humans, their validity
has been shown by others in flies and mammals.
