17β-estradiol lowers triglycerides in adipocytes via estrogen receptor α and it may be attenuated by inflammation.

Background: Estrogen was reported to protect against obesity, however the mechanism remains unclear. We aimed to investigate the impact of 17β-estradiol (17β-E2) on triglyceride metabolism in adipocytes with or without lipopolysacchride (LPS) stimulating, providing novel potential mechanism for estrogen action.

Methods: 3T3-L1 adipocytes were cultured and differentiated into mature adipocytes in vitro.

Combined use of metformin and atorvastatin attenuates atherosclerosis in rabbits fed a high-cholesterol diet.

Statins are widely used to reduce cardiovascular risk. Unfortunately, some patients still experience cardiovascular events though prescribed with high-intensity statins. Metformin, an anti-diabetic drug, was reported to possess anti-atherosclerotic effects.

Estrogen lowers triglyceride via regulating hepatic APOA5 expression.

Estrogen had been found to be negatively associated with serum triglyceride (TG) levels. Apolipoprotein A5 (APOA5), a novel member of apolipoprotein family, was reported to have a strong ability to decrease serum concentrations of TG. Clinical data found concentrations of APOA5 were higher in woman than that in men, and the negative relationship between APOA5 and TG levels was more significant in woman.
