Effects of olive leaf extract (OLE) treatment on nuclear factor erythroid 2-related factor (Nrf2) and heme oxygenase-1 (HO-1) mRNA expression in the testis of rats treated with cisplatin (CDDP). Data of the mRNA expression are expressed as the mean ± SEM of triplicate assays, normalized to the GAPDH mRNA level, and shown as fold change (in log2 scale) relative to the control mRNA levels. ^aSignificant change from the control group at p < 0.05; ^bsignificant change from the CDDP group at p < 0.05 using Tukey's post hoc test.
