Protocol

Animal experiment:

Blood is drawn from the tail vein of each mouse 2 h before the onset of the dark period at the beginning of the study (day 0) and after 2, 4, and 6 days of treatment with 1 mg/day i.p. LEP-(116-130). Blood glucose levels are determined with a Glucometer Elite blood glucose monitor. After 4 and 7 days of treatment with 1 mg/day i.p. LEP-(116-130), sensitivity to cold is examined by placing the mice without food or water in a cold room with an ambient temperature of 4°C. Body temperature is measured with a rectal probe every hour for 4 h.

Background

Leptin (116-130), amide, mouse(C64H109N19O24S),a peptide with the sequence Ser-Cys-Ser-Leu-Pro-Gln-Thr-Ser-Gly-Leu-Gln-Lys-Pro-Glu-Ser-NH2. Leptin is an adipocyte-derived hormone that acts as a major regulator for food intake and energy homeostasis. Leptin deficiency or resistance can result in profound obesity, diabetes, and infertility in humans. Since the discovery of leptin, the breadth of biological actions has dramatically expanded and served to broaden the initial perspective, where this protein was viewed solely as an antiobesity hormone. Important biological activities have been discovered in peripheral tissues that demonstrate the pleiotropic effects of this molecule in such areas as hematopoiesis, angiogenesis, blood pressure, bone mass, lymphoid organ homeostasis, and T lymphocyte function. Recent data indicate that leptin(116-130), an active fragment of the native molecule, exerts effects similar to those of the native peptide on body weight and food intake.
