Global and hepatocyte-specific ablation of Bmal1 induces hyperlipidaemia and enhances atherosclerosis

Abstract

Bmal1 is a key transcription factor that controls rhythmicity of diverse biological functions. Here, Pan et al. show that Bmal1 deficiency in mice increases lipoprotein secretion and reduces cholesterol excretion to bile, and decipher the molecular mechanisms underlying hyperlipidaemia and atherosclerosis promoted by the lack of Bmal1.
