  Resistin / Cushing's Help and Support   (Site not responding. Last check: 2007-10-22)
The hormone, dubbed resistin, is produced by fat cells and prompts tissues to resist insulin, the substance the body needs to process blood sugar, researchers reported in Thursday's issue of the journal Nature.
Mice given resistin were not able to process blood sugar as well as those that were not given the hormone.
Resistin "may form at least part of the missing link between obesity and diabetes,'' Jeffrey S. Flier of the Beth Israel Deaconess Medical Center in Boston said in an accompanying editorial.
