New Insight Into Metformin-Induced Cholesterol-Lowering Effect Crosstalk Between Glucose and Cholesterol Homeostasis via ChREBP (Carbohydrate-Responsive Element-Binding Protein)-Mediated PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) Regulation

Objective: Metformin, a first-line drug for treating individuals with type 2 diabetes, exerts beneficial effects on cholesterol-lowering, yet its precise mechanism has not been established. Approach and Results: In 2 dyslipidemia mouse models, administration of metformin significantly decreased serum cholesterol and PCSK9 (proprotein convertase subtilisin/kexin type 9) levels, accompanied by decreased expression of PCSK9 in both mRNA and protein...
