摘要:

目的研究粘着斑激酶(FAK)在Tca8113舌鳞癌细胞中的表达及对其生长、粘附、侵袭转移能力的影响。方法采用FAK寡核苷酸转染的方法处理Tca8113舌鳞癌细胞,采用逆转录- 聚合酶链反应(RT- PCR)测定FAKmRNA水平的变化,间接免疫荧光方法检测胞浆FAK蛋白的表达,以Transwell小室和冲刷实验的方法计数细胞,测定细胞的粘附和侵袭能力的变化,MTT法检测细胞的生长抑制情况。结果反义FAK寡核苷酸转染后,Tca8113细胞侵袭、粘附、趋化运动能力均显著降低。转染48 h后,FAKmRNA和蛋白水平明显下降(P<0.05)。结论FAK对Tca8113细胞的增殖、存活、粘附及侵袭具有重要作用。

Abstract:

Objective To investigate the effect of FAK on biological characteristics of tongue squamous cell carcinoma cell Tca8113. Methods Lipofect was used to transfect FAK into Tca8113 cell lines. The difference in expression of FAK between the transfected and non- transfected cell lines was detected by immunofluorescence assay. Then by use of transwell room and wash way, the difference in invasion and adhesion ability between the transfected and non- transfected cell lines was tested. MTT method was adopted in finding the change of proliferation. Results RT- PCR analysis showed that the FAK gene was downregulated by Tca8113 cells. FAK expression was significantly down regulated by the transfection of FAK ASODN(P<0.05). Antisense FAK ODN significantly inhibited proliferation, adhesion and the invasion of Tca8113 cells. Conclusion FAK plays an important role on biological characteristics of tongue squamous cell carcinoma cell Tca8113.
