-Endorphin Mediates the Development and Instability of Atherosclerotic Plaques.

-Endorphin, an endogenous opioid peptide, and its -opioid receptor are expressed in brain, liver, and peripheral tissues. -Endorphin induces endothelial dysfunction and is related to insulin resistance. We clarified the effects of -endorphin on atherosclerosis.

CREB3L3 controls fatty acid oxidation and ketogenesis in synergy with PPARα.

CREB3L3 is involved in fatty acid oxidation and ketogenesis in a mutual manner with PPARα. To evaluate relative contribution, a combination of knockout and transgenic mice was investigated. On a ketogenic-diet (KD) that highlights capability of hepatic ketogenesis, Creb3l3 mice exhibited reduction of expression of genes for fatty oxidation and ketogenesis comparable to Ppara mice.

Hepatic CREB3L3 controls whole-body energy homeostasis and improves obesity and diabetes.

Transcriptional regulation of metabolic genes in the liver is the key to maintaining systemic energy homeostasis during starvation. The membrane-bound transcription factor cAMP-responsive element-binding protein 3-like 3 (CREB3L3) has been reported to be activated during fasting and to regulate triglyceride metabolism. Here, we show that CREB3L3 confers a wide spectrum of metabolic responses to starvation in vivo.
