This gene encodes a protein that is secreted by white adipocytes, and which plays a major role in the regulation of body weight. This protein, which acts through the leptin receptor, functions as part of a signaling pathway that can inhibit food intake and/or regulate energy expenditure to maintain constancy of the adipose mass. This protein also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis and wound healing. Mutations in this gene and/or its regulatory regions cause severe obesity, and morbid obesity with hypogonadism. This gene has also been linked to type 2 diabetes mellitus development.

Papers on leptin
Decelerating mature adipocyte dedifferentiation by media composition.
Kluger et al., Stuttgart, Germany. In Tissue Eng Part C Methods, 31 Aug 2015
In our study we showed that DMEM/Ham´s F-12 with 10 % FCS reported for the culture of mature adipocytes favors dedifferentiation, which was accompanied by a high glycerol release, a decreasing release of leptin and a low expression of the adipocyte marker perilipin A, but high expression of CD73 after 21 days.
60 YEARS OF NEUROENDOCRINOLOGY: TRH, the first hypophysiotropic releasing hormone isolated: control of the pituitary-thyroid axis.
Charli et al., Ecatepec, Mexico. In J Endocrinol, 31 Aug 2015
The activity of TRH neurons is regulated by nutritional status through neurons of the arcuate nucleus, which sense metabolic signals such as circulating leptin levels.
Prenatal exposure to persistent organochlorine pollutants is associated with high insulin levels in 5-year-old girls.
Andersen et al., Odense, Denmark. In Environ Res, 29 Aug 2015
OBJECTIVES: In the same birth cohort, we investigated whether prenatal POP exposure was associated with serum concentrations of insulin and leptin among 5-year-old children, thus possibly mediating the association with overweight and obesity at 7 years of age.
Wagner et al., Pomona, United States. In J Steroid Biochem Mol Biol, 28 Aug 2015
Indeed, we have found that leptin robustly suppresses the OFQ/N-induced activation of GIRK channels in POMC neurons.

Wang et al., Nanjing, China. In Biochem Biophys Res Commun, 28 Aug 2015
In conclusion, the study indicated that the molecular expression of genes associated with hormonal regulation differs in dairy cows, depending on their RFI coefficients, and that these differences may be related to the molecular regulation of the leptin-NPY and insulin signaling pathways.

Yajnik et al., Sydney, Australia. In Cell Metab, 08 Aug 2015
Undernourished rats also have higher circulating insulin, homocysteine, endotoxin and leptin levels, lower adiponectin, vitamin B12 and folate levels, and an 8-fold increased susceptibility to Streptozotocin-induced diabetes compared to control rats.
Circadian Dysfunction Induces Leptin Resistance in Mice.
Fu et al., Houston, United States. In Cell Metab, 07 Aug 2015
Our comprehensive screen of wild-type and three circadian mutant mouse models, with or without chronic jet lag, shows that distinct genetic and physiologic interventions differentially disrupt overall energy homeostasis and Leptin signaling.

Mobasheri et al., Santiago de Compostela, Spain. In Life Sci, 18 Jul 2015
Recent data suggests that metabolic factors produced by white adipose tissue, such as leptin, may provide a mechanistic link between obesity and OA, providing an explanation for the high prevalence of OA among obese and over-weight individuals.
