Abstract
AIM: To investigate the effect of human antisense FXYD6 (FXYD domain containing ion transport regulator 6) on the proliferation and invasion of human cholangiocarcinoma cell line QBC939 in vitro.
METHODS: Human cholangiocarcinoma cell line QBC939 was transfected with the plasmid expressing human antisense FXYD6. Meanwhile, the empty vector and non-transfection group were designed. The mRNA transcription level of hFXYD6 was assayed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) with SYBR Green I, and the expression of hFXYD6 protein was detected by immunohistochemistry. MTT and the colony-forming assay were used to measure the ability of cell growth. The cell cycle distribution was analyzed by flow cytometry and Transwell chamber model was employed to test the ability of cell invasion in vitro.
RESULTS: In comparison with the cells transfected with empty vector or without transfection, QBC939 cells transfected with antisense hFXYD6 had a significant decrease in mRNA transcription and protein expression. The cell doubling time was augmented (46.8 h vs 34.5 h, 35.3 h), whereas the colony formation was decreased (24.3% ± 5.3% vs 61.0% ± 8.5%, 58.0% ± 5.6%; P < 0.001). The G1-phase cell population was obviously increased (66.4% ± 2.9% vs 33.5% ± 2.3%, 39.4% ± 3.7%, P < 0.001), but the S-phase one was decreased (18.6% ± 1.6% vs 36.2% ± 2.1%, 34.1% ± 1.6%, P < 0.001). The cells moved from the upper chamber into the lower one in Transwell chamber assay had no marked difference. Between the cells without transfection and transfected with empty vector, there were no significant differences in cell doubling time, colony forming ability, cell cycle distribution and the ability of cell invasion in vitro.
CONCLUSION: Transfection of antisense hFXYD6 can inhibit the ability of cell proliferation, but it has no effect on the ability of cell invasion in human cholangiocarcinoma cell line QBC939 in vitro.
