Overexpression of the ASIC1α gene enhances the mobility and proliferation of HepG2 and SK-Hep1 cells. A1 and A2 Expression levels of ASIC1α in different group cells were detected by western blotting. B1, B2, C1 and C2 Migration abilities of different group cells were examined by wound healing assays. Representative images were taken at × 100 magnification. D1 and D2 Invasion abilities of different group cells were determined by transwell invasion assays. Representative images were taken at × 200 magnification. Invasion assays were conducted at 24 h. E proliferation abilities of different group cells were determined by MTT assay. Data were expressed as the mean ± SD, n = 3. n.s: no significance, *P < 0.05, **P < 0.01 and ***P < 0.001 all versus pH6.5 group or L-02 group
