ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of ANGPTL4 gene silencing on the migration of human colon cancer cells in vitro.</p><p><b>METHODS</b>The expression of ANGPTL4 in human colorectal cancer cell lines was detected by semi-quantitative RT-PCR. Following stable transfection with a short-hairpin RNA (shRNA) targeting ANGPTL4 gene in HT29 cells, ANGPTL4 mRNA and protein expressions were detected by semi-quantitative RT-PCR and direct ELISA, respectively, and the changes in cell migration ability and cell morphology were observed with transwell and immunofluorescence assays.</p><p><b>RESULTS</b>ANGPTL4 was expressed in most of the colorectal cancer cell lines. Compared with the control groups, HT29 cells with shRNA-mediated ANGPTL4 gene silencing showed significantly decreased expression of ANGPTL4 mRNA and protein (P<0.05) and lowered cell migration ability possibly due to decreased pseudopodia formation.</p><p><b>CONCLUSION</b>ANGPTL4 was expressed in most colorectal cancer cell lines. Decreased ANGPTL4 gene expression can inhibit the cell migration and pseudopodia formation in HT29 cells.</p>
