Diarylpropionitrile inhibits the protein (A, B) and mRNA (C, D) expression of RhoA and ROCKII, and even suppresses the site-specific phosphorylation of moesin (Thr558) in CCl4-treated rats (D, E). Shown are the relative densitometric quantifications of all experiments (mean ± SE), with values from the sham-operated controls set to 100 DU. aP < 0.05 vs control group; cP < 0.05 vs DPN group. DPN: Diarylpropionitrile.
