Περίληψη:
Fibroblast growth factor-21 (FGF21) is a pleiotropic protein involved in
glucose, lipid metabolism and energy homeostasis, with main tissues of
expression being the liver and adipose tissue. Brown adipose tissue
(BAT) is responsible for cold-induced thermogenesis in rodents. The role
of FGF21 in BAT biology has not been investigated. In the present study,
wild-type C57BL/6J mice as well as a brown adipocyte cell line were used
to explore the potential role of cold exposure and beta 3-adrenergic
stimulation in the expression of FGF21 in BAT. Our results demonstrate
that short-term exposure to cold, as well as beta 3-adrenergic
stimulation, causes a significant induction of FGF21 mRNA levels in BAT,
without a concomitant increase in FGF21 plasma levels. This finding
opens new routes for the potential use of pharmaceuticals that could
induce FGF21 and, hence, activate BAT thermogenesis. (C) 2011 The
