Fig. 2From: Cigarette smoke exposure impairs lipid metabolism by decreasing low-density lipoprotein receptor expression in hepatocytesMelatonin alleviated the dyslipidemia caused by CS. The levels of serum TGs, TC, and LDL-C (a–c) in the CS group were higher than those in the control group, while the HDL-C (d) was lower than that in the control group. Furthermore, melatonin supplementation lowered blood lipid levels (a–c). *P < 0.05, ns. P > 0.05Back to article page
