Figure Lengend Snippet: Downregulation of miR-300-3p promotes FFA-induced lipid accumulation and hepatic inflammation in HepG2 cells. (A) The experimental flow of the MAFLD cell model construction and miR-300-3p mimics, miR-300-3p inhibitors and as well as corresponding scrambled controls transfection in HepG2 cells. (B,C) Intercellular TG contents in miR-300-3p -inhibited and -overexpressing in HepG2 cells. (D) Oil Red O staining (400×) and the relative areas of lipid droplets in miR-300-3p-inhibited and -overexpressing in HepG2 cells. (E,F) mRNA levels of FASN, SREBP-1c, IL-6, IL-2 and TNF-αin miR-300-3p -inhibited and -overexpressing in HepG2 cells. (G) Protein levels of FASN, SREBP-1c and TNF-α in miR-300-3p -inhibited and -overexpressing in HepG2 cells. Data in (B,C) and (E–G) are means±SDs (n = 3). *P < 0.05, **P < 0.01, *** P < 0.001, **** P < 0.0001. OC, over-expression control; IC, inhibition control.
Article Snippet: The human hepatocyte cell line HepG2 was procured from the American Type Culture Collection (ATCC, United States) and cultivated in a humidified incubator maintained at 37 °C with a 5% CO 2 atmosphere.
