Diarylpropionitrile increases the hepatic expression of NO/PKG pathway proteins and increases their activity but inhibits hepatic iNOS expression in CCl4-treated rats. A: Western blot analysis of eNOS, p-eNOS, VASP, p-VASP, and iNOS protein expression; B: Relative densitometric quantifications of all experiments (mean ± SE), with the values from the controls set to 100 DU (each group n = 5). aP < 0.05 vs control group; cP < 0.05 vs DPN group.
