Effect of sulforaphane (SFN) on the levels of Nrf2 and downstream proteins HO1 and NQO1 in rat TNC 4 h after NTG injection. a Representative immunoblots of TNC. Nuclear Nrf2 b, HO1 c and NQO1 d levels were significantly increased in the SFN plus NTG group compared to those in the H2O plus NTG group. Moreover, these protein expressions were increased in the SFN plus control group compared to those in the control group b, c, d. Data are presented as the mean ± SD. (* P < 0.05, ** P < 0.01, n = 6 per group)
