Figure 1

Redox response system of P. lividus reproductive tissues (testis and ovary) after exposures to high (H), low (L) doses of Cd, Zn or a mix of both metals, as reported in Table 1. (A) Total ROS amount; (B) catalase activity; (C) relative HSP70 protein amount; (D) relative HSP60 protein amount; (E) relative HSP90 protein amount. Bars represent the mean values from the three different experiments ± SD. Statistical significance among testis and ovary results is shown as asterisks (*: p < 0.05; **: p < 0.01; ***: p < 0.001). Letters denote statistical significance of treated specimens vs. controls (b: p < 0.01; a: p < 0.001).
