Creb3l3 deficiency promotes intestinal lipid accumulation and alters ApoB-containing lipoprotein kinetics.

ABSTRACT: Elevated levels of triglycerides in the bloodstream, a condition known as hypertriglyceridemia, represent a significant risk factor for the development of metabolic disorders and cardiovascular diseases. One key regulator of lipid metabolism is the transcription factor cAMP-responsive element-binding protein 3-like 3 (CREB3L3), which is expressed in the liver, intestine, and adipose tissue. CREB3L3 is localized to the endoplasmic reticulum membrane, and in vertebrates plays a crucial role in plasma lipid homeostasis. However, the precise molecular mechanisms underlying Creb3l3's influence on cellular lipid metabolism remains undefined. To address this knowledge gap, we generated zebrafish mutants lacking both creb3l3 orthologs (creb3l3a and creb3l3b). Gene expression analysis revealed that
