Objective To investigate the effect of CHD1L silencing by RNAi on the growth and invasion of intrahepatic cholangiocarcinoma(ICC) cells line. Methods The protein and mRNA expressions of CHD1L in three types of ICC cell lines, RBE, HCCC-9810 and HUCCT1, were determined by Western blot and q RTPCR. The overexpression of CHD1L cell line was selected and after transfection with CHD1L-RNAi, the protein expressions of CHD1L were measured by Western blot. CCK-8 assay and plate clone formation assay were used to de...
