The effects of nm23-H1 on metastases ability and chemo-sensitivity in Tca8113 cell lines / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The purpose of this study was to establish a stable, high-efficient and low-toxic way of transfecting nm23-H1 into Tca8113 line cells, and then to find out whether nm23-H1 could affect the invasion and metastases ability of Tca8113 line cells.</p><p><b>METHODS</b>nm23-H1 was transfected into Tca8113 line cells with Lipofect. The different expressions of nm23-H1 between transfected and non-transfected line cells were detected by the method of immunohistochemistry. The difference of the invasion and metastases ability between transfected and non-transfected line cells was detected by transwell-room and wash techniques. The change of chemo-sensitivity was evaluated by MTT.</p><p><b>RESULTS</b>Using pCMV-NEO-BAM system to keep stable expression of nm23-H1, the significant difference of NDPKA expression between transfected and non-transfected Tca8113 line cells was discovered; The metastases ability of transfected Tca8113 line cells decreased significantly; The chemo-sensitivity of transfected Tca8113 line cells to CDDP increased significantly.</p><p><b>CONCLUSION</b>nm23-H1 can inhibit the metastases of Tca8113 line cells and increase the chemo-sensitivity to CDDP significantly.</p>
