Fat Genes?

Gene manipulation that created sleek and trim roundworms may ultimately help scientists develop new obesity treatments.

A Harvard biologist identified about 400 roundworm genes related to fat production and storage. His team then turned off about 300. He says the experiments left the worms "thin and happy." When the researchers turned off the over 100 genes, the worms gained weight.

The researcher says people and roundworms share about 200 fat storage genes. He says he can't tell if the fat-gene knockout technique would work in people. But he says his genetics research might lead to new obesity drugs.

The study is in the journal Nature.
