Leptin action in intestinal cells.
The adipocyte hormone leptin activates signal transducer and activator of transcription 3 (STAT3) in the hypothalamus, mediating increased satiety and increased energy expenditure. To date, leptin-mediated activation of the STAT pathway in vivo has not been established in tissues other than hypothalamus. We now describe leptin receptor expression and in vivo signaling in discrete regions of the...

متن کاملLeptin receptor signaling and action in the central nervous system.
The increasing incidence of obesity in developed nations represents an ever-growing challenge to health care by promoting diabetes and other diseases. The discovery of the hormone, leptin, a decade ago has facilitated the acquisition of new knowledge regarding the regulation of energy balance. A great deal remains to be discovered regarding the molecular and anatomic actions of leptin, however....
متن کاملLeptin receptor mRNA expression in Taleshi ram gonads
Leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. Leptin and itsreceptor (Ob-R) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. The goal of this study was determination of the presence of leptin receptor mRNA in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...
متن کاملExpression of leptin receptors in hepatic sinusoidal cells
Emerging evidence has suggested a critical role of leptin in hepatic inflammation and fibrogenesis, however, the precise mechanisms underlying the profibrogenic action of leptin in the liver has not been well elucidated. Therefore, the present study was designed to investigate the expression and functions of leptin receptors (Ob-R) in hepatic sinusoidal cells. Hepatic stellate cells (HSCs), Kup...
