[Transfection of the nm23-H1 gene into BcaCD885 cell line inhibits the potential of invasion, adhesion and mobility].

OBJECTIVE: To transfect nm23-H1 into the BcaCD885 cell lines in order to get safe high-efficiency and low-toxicity, and to find out whether nm23-H1 could affect the invasion and metastases ability of BcaCD885 cell lines. METHODS: Lipofect was used to transfect nm23-H1 into BcaCD885 cell lines; immunohistochemistry was used to detect the difference expression of nm23-H1 between transfected and non-transfected cell lines; then transwell-room and wash way were used to detect the difference of invasion and metastases ability between transfected and non-transfected cell lines. RESULTS: PCMV-NEO-BAM system gave the stability expression of nm23-H1; there was significant different NDPKA expression between transfected and non-transfected BcaCD885 cell lines; the invasion and metastases ability of transfected BcaCD885 cell lines decreased obviously. CONCLUSION: nm23-H1 can inhibit the metastases of BcaCD885 cell lines significantly.
