MRTF-A regulates Abl1 expression in activated hepatic stellate cells in vitro. (A,B) Primary HSCs isolated from WT and MRTF-A KO mice were spontaneously activated in culture for 7 days. Gene expression levels were examined by qPCR and Western. (C,D) LX-2 cells were transfected with small interfering RNA targeting MRTF-A or scrambled siRNA (SCR) followed by treatment with PDGF-BB. Gene expression levels were examined by qPCR and Western. (E,F) LX-2 cells were treated with PDGF-BB in the presence or absence of CCG-1423 (1–10 μM). Gene expression levels were examined by qPCR and Western. All experiments were repeated three times and one representative experiment is shown. Error bars represent SD (∗p < 0.05, one-way ANOVA with post hoc Scheffe test).
