Effects of strawberry methanolic extract (SME) treatment on superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase activities and their corresponding mRNA expressions in testis of rats exposed to cadmium (CdCl₂) toxicity. Data of antioxidant enzyme activities are expressed as the mean ± SEM (n = 8) while the data of the mRNA expressions (mean ± SEM of triplicate assays) were normalized to the GAPDH mRNA level and are shown as the fold induction (in log2 scale) relative to the mRNA level in the controls. ^a Indicate significant change from the Control at p < 0.05; ^b indicate significant change from the CdCl₂ at p < 0.05 using Duncan’s post hoc test.
