Fig. 4. circFASN induced triglyceride accumulation by “sponging” miR-33a.

Fig. 4

a circFASN was successfully overexpressed in Huh7 and Hep-G2 cells. b The linear form of FASN was not affected by the circFASN overexpression plasmid. c Relative expression of miR-33a, detected by qPCR, was reduced in the circFASN overexpression (OE) groups in Huh7 and Hep-G2 cells. d circFASN was silenced in Huh7 and Hep-G2 cells. e The linear form of FASN was not affected by silencing circFASN. f The relative expression of miR-33a, detected by qPCR, was increased in the circFASN-silenced Huh7 and Hep-G2 cells. g, h Triglyceride levels in Huh7 and Hep-G2 cells measured by the glycerol lipase oxidase (GPO-PAP) method. i Protein levels of ABCG1 and CPT1A in Huh7 and Hep-G2 cells determined by western blotting. Data represent the mean ± SD. *P < 0.05, **P < 0.01, NS, not significant. The experiments were independently repeated at least three times.
