The effect of ezrin small interfering RNA (siRNA) and administration of ERK inhibitor (FR180204) on 3D-cultured HSC-3 and HSC-4 cells. a Expression of ezrin and p-cortactin (Tyr421) after siRNA treatment. Suppression of ezrin expression was observed in siEzrin cells in 3D-cultured HSC-3 and HSC-4 cell lines, but no difference was observed in the expression of p-cortactin (Tyr421) (n = 3). b Expression of p-ERK and cortactin and p-cortactin (Tyr421) following treatment with ERK inhibitor. In both 3D-cultured HSC-3 and HSC-4 cell lines, p-ERK expression was suppressed in FR cells, but no difference was observed in the expression of t-ERK. In addition, in FR cells, although no difference was observed in the expression of cortactin, p-cortactin (Tyr421) expression was significantly suppressed (n = 3)
