Fig. 3. GSTM2 modulated cellular lipid droplets accumulation via regulating cellular ROS level.
a, b Expression level of GSTM2 was detected in shGSTM2-HepG2 cells and corresponding control cells. c More LDs were observed in shGSTM2-HepG2 cells. d Statistics of LD number in shGSTM2-HepG2 cells and shNC-HepG2 cells. e More larger LDs were found in shGSTM2-HepG2 cells treated with 1 mM oleic acid medium for 12 h compared to control cells. f Statistics of LD diameter in shGSTM2-HepG2 cells and shNC-HepG2 cells treated with 1 mM oleic acid medium for 12 h compared to control cells. g Cellular ROS level was detected in shGSTM2-HepG2 and shNC-HepG2 cells in the presence or absence of oleic acid medium; *p < 0.05, **p < 0.01. h More LDs were observed in cells treated with ROSup compared to control cells. i Statistics of LD number in cells treated with ROSup and control cells.
