Effect of NTG injection on the levels of Nrf2 downstream proteins HO1 and NQO1 in rat TNC. a Representative immunoblots of TNC. Compared to the NS group or NTG 0 h group, HO1 levels were elevated at 0.5 h, 1 h, 2 h, and 4 h after NTG injection b and NQO1 levels were elevated at 1 h, 2 h, and 4 h after NTG injection c. β-actin was used as the loading control. Data are presented as relative density units normalized to β-actin, and expressed as mean ± SD. (* P < 0.05 vs the control group, **P < 0.01 vs the control group, # P < 0.01 vs NTG 0 h group, n = 6 per group)
