(A) Comparisons of mRNA expression of Nrf2 signaling pathway in HSC-4 and HSC-4-RR cell lines before and after transfection. (B) Comparisons of protein expression of Nrf2 by Western blotting in HSC-4 and HSC-4-RR cell lines before and after transfection. (C) Comparisons of protein expression of Nrf2 signaling pathway in HSC-4 and HSC-4-RR cell lines before and after transfection. *P<0.05 compared with the HSC-4-NC group; #P<0.05 compared with the HSC-4-RR-NC group; &P<0.05 compared with the HSC-4-Nrf2 siRNA group.
