Fig 1: Trox reduced the production of free radicals and favored the expression of anti-oxidative proteins. Our data demonstrated via Western blot analysis of the 8305C cell lysates that Trox at the concentrations of 100 and 300 μg/mL favored the expression of MnSOD ((A), densitometric analysis (A1)). The ELISA kit assay showed that Trox increased the concentration of anti-oxidant protein GSH (B) and reduced the concentration of pro-oxidative protein ROMO1 (C). * p < 0.05 vs. 8305C; ** p < 0.01 vs. 8305C.
