title: Adipocyte hormone responsiveness and aging in the rat: problems in the interpretation of aging research.
abstract: Fat is a metabolically dynamic tissue. Its metabolism is under the control of several well-characterized hormonal systems. There appear to be changes in the hormonal sensitivity of rat fat with age. No single mechanism has been proved to explain all the changes observed in adipocyte hormonal responsiveness with aging, although it does seem likely that age does have an independent effect on fat metabolism from studies to date.
