Effect of geniposide on the activities of SOD, GSHPx and catalase in formaldehyde-injured SH-SY5Y cells. After treatment of cells with different concentrations of geniposide (25, 100 μM) and 0.12 mM formaldehyde for 24 h. SOD activity ( A ), GSHPx activity ( B ) and catalase activity ( C ) were measured using assay kits and a microplate reader. Cells treated with formaldehyde alone and those with no treatment were used as positive and negative controls, respectively. Gp, geniposide. The data are represented as the mean ± SD from three independent experiments. *P < 0.05 and **P < 0.01 vs. group treated with formaldehyde alone.
