Abstract: The semi-quantitative RT-PCR method was applied to test the expression of CuZn-SOD gene and Mn-SOD gene in Takifugu rubripes hepatopancreas after phenol exposure. Fish was cultured in seawater containing 0, 0.18, 0.32, 0.56, 1.00 and 1.35 mg/L phenol, respectively, and was sampled before phenol exposure and after 4, 8, 12 and 16 d phenol exposure. The results show that basal expression of CuZn-SOD gene and Mn-SOD gene were detected in fish before phenol exposure. The relative expression levels of CuZn-SOD and Mn-SOD mRNA showed a trend of gradual up-regulation throughout the 16 days phenol exposure and the phenol induced the expression of CuZn-SOD and Mn-SOD gene. The mRNA expression level in each phenol exposure group peaked at the fourth day and was significantly higher than that of the phenol pre-exposure level(P<0.05).
