(A) Western analysis of overall expression of SOD1, SOD2, catalase, Gpx1, NQO1, HO-1, Hsp70, GSTA4, GSTμ and GSTπ. Western blots were performed as described using 10μg of whole cell extracts prepared from normal, PSC/IBD hepatic tissue. Expression was normalized against GAPDH expression (B) Overall GST activity in whole cell extracts prepared from normal and PSC/IBD patients. Data are Means+/−SEM, N=6 patients per group, *p<0.05, ***p<0.001.
