Effects of H2S on SM-induced changes in the expression of Nrf2 downstream genes in mouse lung tissues. Mice were subcutaneously injected with SM (30 mg/kg), with or without intraperitoneal administration of NaHS (5 mg/kg) or intraperitoneal administration of PPG (30 mg/kg), addition NaHS and PPG were given every day for a total of three doses. The protein levels of Nrf2 downstream including HO-1 (A) and NQO1 (B). The mRNA levels of Nrf2 downstream target cytoprotective genes including HO-1, NQO1, GCLC, GR, and GCLM in lungs tissues were determined by RT-PCR (C). Data are presented as the mean ± SEM (n = 4). *p < 0.05 vs CTRL group; **p < 0.01 vs CTRL group; #p < 0.05 vs SM group; ##p < 0.01 vs SM group.
