Interference effects of DCN, GPAM, DGAT2, G6PD, and LPL on adipocyte adipogenesis. (A) Bright field microscopy of lipid droplets in DCN- and LPL-interfered preadipocytes followed by differentiation at day 5 (magnification: 100×). As there were no obvious lipid droplets observed in the bright field microscopy when interfering GPAM, DGAT2, and G6PD, the data was not shown. (B–C) Oil Red O staining of lipids (magnification: 40×) and ELISA analysis of TG content showed that DCN, G6PD, and LPL were strongly anti-adipogenic while GPAM and DGAT2 were pro-adipogenic in adipogenesis. Error bars represent SEM. “*” represents p < 0.05.
