Figure 6. Catalase, but not eSOD3, participates in the antioxidant response of the Gpx5^–/– cauda epdidymidis.

(A) Schematic representation of the ROS recycling pathway using the catalytic triad of scavengers. (B) Quantitative RT-PCR estimations of eSOD3 and catalase mRNA accumulations in caput and cauda epididymis samples from WT and KO male mice, using the cyclophilin transcript as a reference. Data are mean ± SEM. n = 2. **P < 0.05.
