Generation levels of (A) hydrogen peroxide (H2O2), (B) superoxide anions (SA), (C) lipid peroxides (LPO), and (D) protein carbonyl content (PCC), and transcriptional and enzyme activities of thioredoxin reductase 2 (TrxR2) (E, F) and superoxide dismutase 2 (SOD2) (G, H) in young (P5) and senescent (P25 and P35) confluent cells. **p < 0.01), ***p < 0.001, and ****p < 0.0001 indicate significant difference from control P5 values (n = 6).
