Apolipoprotein F is reduced in humans with steatosis and controls plasma triglyceride‐rich lipoprotein metabolism

Hepatology, EarlyView., 2022
Hepatic APOF transcript levels correlate inversely with plasma TG and hepatic steatosis in humans. ApoF expression in mice promotes VLDL‐TG production and lipoprotein remnant clearance in mice. Abstract Background NAFLD affects nearly 25% of the global population. Cardiovascular disease (CVD) is the most common cause of death among patients with NAFLD,
