Abstract
AIM: To investigate the impact of fragile histidine triad (FHIT) gene transfection on the proliferation and invasiveness of human cholangiocarcinoma QBC939 cells.
METHODS: The recombinant FHIT eukaryotic expression plasmid was introduced into QBC939 cells by liposome-mediated transfection. Cell proliferation was tested by methyl thiazolyl tetrazolium (MTT) assay. Cell invasion was determined by Transwell chamber assay.
RESULTS: MTT assay showed that FHIT gene transfection significantly decreased the proliferation of QBC939 cells (P < 0.05). Transwell chamber assay showed that the number of transfected cells that passed the Transwell membrane was significantly less than those of blank control and normal control cells (48 ± 7 vs 109 ± 14 and 104 ± 12, respectively; both P < 0.01).
CONCLUSION: FHIT gene can inhibit the proliferation and invasiveness of human cholangiocarcinoma QBC939 cells.
