Analysis of OSTF1, TFIIB, and Hsp70 mRNA expression during oxidative stress (1 mM H2O2) and heat shock (+10°C). OSTF1 (A), TFIIB (B), and Hsp70 (C) transcript levels of fish exposed to oxidative stress or heat shock for 2 h were measured by using quantitative RT-PCR. Experiments were performed with n = 6. Data are shown as means ± SEM. *, P < 0.05; **, P < 0.01, compared with control sample (FW, 26°C).
