The hormone leptin indirectly communicates metabolic information to brain neurons that control reproduction, using GABAergic circuitry. Agouti-related peptide (AgRP) neurons in the arcuate nucleus are GABAergic, express leptin receptors (LepR), and are known to influence reproduction. This study tested whether leptin actions on AgRP neurons are required and sufficient for puberty onset and subs...
B ecause obesity is a powerful risk factor for the development of type 2 diabetes, genes involved in the pathogenesis of obesity might also play a role in type 2 diabetes (1). In obese subjects, heterozygous carriers of a pentanucleotide insert ion in the 3 untranslated region (UTR) of the LEPR gene had lower serum insulin concentrations than subjects homozygous for the more common deletion all...
AIM To investigate the expression and immunohistochemical localization of leptin receptor (LEPR) in human periapical granulomas. METHODOLOGY Periapical inflammatory lesions were obtained from extracted human teeth and teeth which underwent periapical surgery. After their histopathological categorization as periapical granulomas (n = 20), they were examined by immunohistochemistry using human ...
INTRODUCTION Leptin (LEP) and its receptor (LEPR) participate in the immunological response during infection. LEP serum levels rise during sepsis. In patients with peritonitis, an insufficient elevation in serum LEP is associated with an increased risk of death. As gene variants of LEP and LEPR have been associated with diverse pathologic conditions, we explored the association of genetic polym...
Obesity is due to the combined effects of genes, environment, lifestyle, and the interactions of these factors. The adrenergic receptor beta3 (beta3-AR), leptin (LEP) and leptin receptor (LEPR) genes have been intensively evaluated in the search of variants that could be related to obesity and its cardiometabolic complications. The results of most of these studies have been controversial. In th...
Leptin, an adipocyte-derived cytokine (adipokine), has plethora of physiological roles in the body, particularly onset puberty, reproduction and immune function animal. Leptin binds with leptin receptor (LEPR) activates different intracellular signaling pathways to activate downstream gene expression process execute its functions. The present mini-review focuses on our current understanding abo...
Single nucleotide polymorphisms (SNPs) in energy metabolism related gene may be key agents in the development of human malignancies. In this study, we aimed to examine the association of transcription factor 7-like 2, Leptin (LEP) and LEP receptor (LEPR) polymorphisms with esophageal squamous cell carcinoma (ESCC). A total of 507 ESCC cases and 1,496 controls were enrolled. We found that LEPR r...
In a population-based case-control study, obesity was associated with elevated odds ratios (ORs) for non-Hodgkin lymphoma (NHL), and the two major subtypes, diffuse large cell (DLCL) and follicular lymphoma (FL). Those who were obese (body mass index >/= 30) were up to three times more likely to develop NHL or its major subtypes than persons with body mass index of 20 to <25. Obesity-related ge...
We have generated mice that carry a neuron-specific leptin receptor (LEPR) transgene whose expression is driven by the rat synapsin I promoter synapsin-LEPR B (SYN-LEPR-B). We have also generated mice that are compound hemizygotes for the transgenes SYN-LEPR-B and neuron-specific enolase-LEPR B (NSE-LEPR-B). We observed a degree of correction in db/db mice that are hemizygous (Syn db/db) and ho...
We have generated mice that are homozygous for a leptin receptor transgene that is expressed exclusively in neurons (NSE-LEPR-B). We had previously shown that this transgene in the hemizygous state is effective in ameliorating almost all aspects of leptin receptor deficiency. Now, we show that the transgene, in the homozygous state, almost fully corrects the excess adiposity of LEPR-deficient (...
