Leptin recruits Creb-regulated transcriptional coactivator 1 to improve hyperglycemia in insulin-deficient diabetes.

Molecular metabolism

Kim GH, Szabo A, King EM, Ayala J, Ayala JE, Altarejos JY.
PMID: 25737949
Mol Metab. 2014 Dec 19;4(3):227-36. doi: 10.1016/j.molmet.2014.12.006. eCollection 2015 Mar.

OBJECTIVE: Leptin alleviates hyperglycemia in rodent models of Type 1 diabetes by activating leptin receptors within the central nervous system. Here we delineate whether non-canonical leptin signaling through the Creb-regulated transcriptional coactivator 1 (Crtc1) contributes to leptin-dependent improvements in...
