Description

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline.

Application

Leptin from rat has been used:
• to check the effect of intranasal nerve growth factor (NGF) on NGF activity in the spinal cord of Sprague-Dawley rats
• for validation of labelling for leptin-bearing cells of Sprague-Dawley rats
• to study the effect of leptin on STAT3 (signal transducer and activator of transcription 3) phosphorylation in neural population of Sprague-Dawley rats
• to study leptin response towards chemoreflex in nucleus of the solitary tract
• in rats, to check the effect of association between leptin and neuronal nitric oxide pathway on penicillin-induced epileptiform activity

Biochem/physiol Actions

In rodents with uncontrolled diabetes mellitus, leptin is crucial for normalizing hyperglycemia. In the digestive tract, it also participates in the absorption of dietary molecules via controlling transporters activity.

Leptin is a hormone produced primarily in adipocytes, although leptin mRNA has also been identified in placenta and fetal tissues, gastric tissue and liver. Its primary site of action appears to be on neurons in the hypothalamus that are involved in regulating energy balance, appetite, and body weight. Leptin increases the production of nitric oxide in endothelial cells and stimulates angiogenesis in vitro and in vivo.
Human and mouse leptin share ~84% sequence identity.

Lipid Induced Insulin Resistance

Obesity is a well-established risk factor for the development of insulin resistance. Obesity is associated with the increased deposition of lipids in non-adipose tissue with subsequent decreases in i...
