Leptin (from the Greek leptos=thin) was identified only 3 years ago. It has attracted huge attention both scientifically, with more than 600 publications, and in the media, where this protein has been portrayed as the way to a cure for obesity. Indeed, leptin was first described as an adipocyte-derived signalling factor, which, after interaction with ...

A highly conserved protein called 'leptin' was recently discovered to play a role in regulation of the energy balance in humans and rodents. This 167-amino-acid-containing protein is only produced and secreted by mature adipocytes. Absence of the protein in mutant ob/ob mice and resistance to its effects in db/db mice lead to extreme obesity and type ...

Leptin belongs to the helical cytokine family and has structural similarity to interleukin (IL)-6, IL-12, IL-15, prolactin, and growth hormone. It is mainly secreted by adipocytes but (at lower levels) also by stomach, skeletal muscle, and placenta.

Mechanisms of Leptin Action and Leptin Resistance
Annual Review of Physiology, 2008The adipose tissue–derived hormone leptin acts via its receptor (LRb) in the brain to regulate energy balance and neuroendocrine function. LRb signaling via STAT3 and a number of other pathways is required for the totality of leptin action. The failure of elevated leptin levels to suppress feeding and mediate weight loss in common forms of obesity ...

Leptin, a hormone secreted from adipose tissue, plays an important role in reproductive physiology. It has been shown to stimulate the reproductive system by rescuing the sterility of leptin-deficient mice and advancing the onset of puberty in normal mice.

Placental tissues from humans, rodents and farm animals contain leptin and its receptor. Leptin produced by the human placenta has the same size, charge and immunoreactivity as leptin produced by adipose tissue. However, the expression of human placental leptin appears to be regulated by a placenta-specific upstream enhancer.

Expression of Placental Leptin and Leptin Receptors in Preeclampsia
International Journal of Gynecological Pathology, 2004This study investigated the expression profile of placental leptin and leptin receptor isoforms in preeclampsia, using placental tissue from normal pregnancies that were matched in gestational age and birth weight as controls. A total of 29 cases of preeclampsia were studied by immunohistochemistry, including 16 severe and 13 mild preeclampsia cases ...

Plasma leptin levels in pigs with different leptin and leptin receptor genotypes
Journal of Animal Breeding and Genetics, 2008SummaryA C3469T mutation at exon 3 of the pig leptin (Lep) gene has been genotyped in diverse pig breeds yielding controversial results with regard to its association with growth, fatness and carcass traits. A similar situation has been reported for a HpaII restriction fragment length polymorphism (RFLP) in the pig leptin receptor (Lepr) gene, where ...

AbstractThe prevalence of obesity has markedly increased over the past two decades, especially in the industrialized countries. While the impact of excess body weight on the development of cardiac disease and diabetes has been well documented, the link between obesity and carcinogenesis is just being recognized.
