Hepatic gene expression profiling reveals key pathways involved in leptin mediated weight loss in ob/ob mice.


ABSTRACT: The purpose of this study was to identify leptin target genes and subsequent pathways correlated with leptin-mediated weight loss. We utilized the microarray technology to compare two types of leptin administration: one involving a direct stimulatory effect when administered peripherally (subcutaneous: SQ) and another that is indirect, involving a hypothalamic relay that suppresses food intake when leptin is administered centrally (intracerebroventricular: ICV). We report here the impact of central and peripheral administration of leptin on food intake, body weight and body fat composition in ob/ob mice. We also report hepatic gene expression changes caused by central versus peripheral leptin administration. Keywords: comparison
