| Abstract：［Objective］ To investigate the effect of FMNL2 gene silence on the proliferation of invasion of human colorectal cancer(CRC) cells in vivo and in vitro．［Methods］ Human colorectal cancer SW80/M5 cells were transfected with FMNL2 specific shRNA plasmid vectors，and FMNL2- silenced cells were screened by G418. Quantitative RT-PCR and Western blot analysis were used to detect the expressions of FMNL2 mRNA and protein，respectively. The cell proliferation was determined by CCK8 assay，the cell invasion ability was detected by boyden invasive assay in vitro. Tumorigenesis and metastasis in vivo were examined by whole-body visualizing hepatic metastasis animal model in nude mice. ［Results］ FMNL2 silencing inhibited cell proliferation，migration and invasion (P<0.05) in vitro and in vivo.［Conclusion］ FMNL2 gene may have multiple biological functions during colorectal cancer progression and it may used as a novel therapeutic target against CRC． |
