Knocking down ABL2 expression decreased the protein levels related to migration, proliferation, and EMT in GC cells. (A) Left, Representative image shown the expression of E-Cadherin, N-Cadherin and Snail in MGC-803 cells transfected with NC and si-ABL2. Right, Quantitative analysis of EMT-related proteins' relative expression levels. (B) Left, Representative image shown the expression of E-Cadherin, N-Cadherin and Snail in HGC-27 cells transfected with the Arg Lentiviral Activation Particles and Vector. Right, Quantitative analysis of EMT-related proteins' relative expression levels. (C and D) Left, Representative image shown the expression of MMP2, MMP9, PCNA, TIMP1 and TIMP2 in MGC-803 cells (C) or HGC-27 cells (D) with knocked down or overexpressed ABL2 expression. Right, Quantitative analysis of migration- or proliferation- proteins' relative expression levels. Data are presented as the mean ± SD of 3 independent experiments. *P<0.05, **P<0.01, ***P<0.001.
