Transcriptional Characterization of Porcine Leptin and Leptin Receptor Genes

Transcriptional Characterization of Porcine Leptin and Leptin Receptor Genes

The leptin (LEP) and its receptor (LEPR) regulate food intake and energy balance through hypothalamic signaling. However, the LEP-LEPR axis seems to be more complex and its expression regulation has not been well described. In pigs, LEP and LEPR genes have been widely studied due to their relevance. Previous studies reported significant effects of SNPs located in both genes on growth and fatnes...

Mutations in the human leptin and leptin receptor genes as models of serum leptin receptor regulation.

A part of serum Ob leptin, an adipocyte-secreted peptide, is bound to a soluble Ob receptor (sObR). Immunoreactive sObR was measured in 125 lean or obese control subjects (group 1), 18 individuals with a mutation in the leptin gene impairing leptin secretion (group 2), and 10 individuals with a mutation in the ObR gene, leading to production of a truncated ObR not anchored to cell membranes (gr...

Expression of leptin and leptin receptor transcript in ovine corpus luteum

Background: Leptin, the product of the obesity (ob) gene, acts as a signaling adipokine for modulating food intake, energy metabolism and reproductive functions in mammals. Leptin’s effects on the reproductive system at various levels of the hypothalamic-pituitary-gonadal axis have been established. Moreover, the direct and local effect of leptin on bovine oocyte maturation and corpus luteum fu...

Detection of leptin and leptin receptor mRNA expression in the bovine t

the association of polymorphisms in leptin/leptin receptor genes and ghrelin/ghrelin receptor genes with overweight/obesity and the related metabolic disturbances: a review

conclusions in general, our study suggests that the association between lep/lepr and ghrl/ghsr with overweight/obesity and the related metabolic disturbances is inconclusive. these results may be due to unidentified gene-environment interactions. more investigations are needed to further clarify this association. results the most prevalent leptin/leptin receptor genes (lep/lepr) and ghrelin/ghr...
