Disruption of Leptin Signaling Contributes to Cardiac Hypertrophy Independently of Body Weight in Mice

Abstract

Together these data show that the effect of leptin on LV remodeling is not attributable to weight loss alone, indicating that leptin has antihypertrophic effects on the heart, either directly or through a leptin-regulated neurohumoral pathway. Disruption of leptin signaling may represent a novel mechanism in LVH and related cardiovascular disorders.
