...stuff I already knew," said Gregory R. Friedman...
...Both Friedman and Rosario said the cause might be better served by an organized event to let students meet and talk to faculty...
...regulation--and how the whole system can go awry. With that understanding, they believe, it may be possible to develop drugs that do the job balky genes fail to do--controlling a problem that decades of fad diets and self-help books have never solved. Says molecular biologist Jeffrey Friedman of the Howard Hughes Medical Institute at Rockefeller University in New York City: "Genomics will identify the players in this system, eventually leading to new targets and new treatments...
...discovery of leptin in 1994 that got the genetic study of obesity rolling, and it was Friedman's research team that was responsible. Studying the genome of a rare strain of hugely obese mice, the investigators found that all of them shared a defect in a gene that coded for a previously unknown hormone released by body fat. When a normal animal gains too much weight, the hormone signals the brain to turn down the appetite rheostat. When fat stores drop, the hormone is shut off, causing appetite to rebound. In the gene-damaged mice, there was no leptin...
...announcement of leptin's discovery was big news to biologists, particularly after Friedman administered it to the obese mice and saw their weight drop by a dramatic 30% within as little as two weeks. A next, obvious step was to look for humans with the same defective gene. In Britain, endocrinologist Stephen O'Rahilly of the University of Cambridge did find a pair of leptin-deficient children, one of whom at age 9 weighed a staggering 208 lbs. After modest leptin treatments were begun, both children began dropping weight at a steady rate that sometimes exceeded 4 lbs. a month...
