Leptin

the journal Genes & Development, M. Friedman, an HHMI investigator

at The Rockefeller University, and Rockefeller colleagues Soukas,

Cohen and D. Socci report that they are beginning to probe the

genetic program orchestrated by leptin to induce weight loss.

" We knew that an animal given leptin eats less and loses fat, " said Friedman

" And while restricting food intake also causes weight loss, we had reason

to believe that the two weight-loss responses are very different. " For

example, said Friedman, leptin triggers weight loss of fat stores alone,

while food-restriction robs the body of both fat and muscle. Also, he said,

a diet-restricted human or animal compensates for decreased caloric intake

by lowering energy expenditure, while leptin treatment shows no such

energy-robbing effect. Until now, however, no one had explored the molecular

basis of such differences in detail, said Friedman.
