Effects of catalase over-expression on HeLa cells treated with PL. (A) Representative blot and densitometry measurement of Prx-2 oxidation for HeLa and HeLaCat treated with 10 μM PL. The Prx-2 oxidation state of HeLa cells overexpressing catalase in the cytoplasm (HeLaCat) was compared to HeLa on 10-h incubation with PL. The bar graph represents mean ± standard deviation from two biological replicates. (B) Growth inhibition of HeLa cells treated with PL, PL + TEMPOL, PL + mitoTEMPO, and HeLaCat treated with PL. Cell viability was determined after 48 h. The bar graphs represent mean ± standard deviation from two biological replicates and two technical replicates. *p < 0.05, **p < 0.01.
