ABSTRACT
Objective To construct a stable expression plasmids miR-218,to lay the experimental foundation for the expression and mechanism of miR-218 in human renal cell carcinoma.Methods The primers were designed by Has-miR-218 and the miR-218 fragment were amplified by PCR,and then which was connected with the carrier pcDNA3.1 (+) to build a stable expression plasmids.The recombinant plasmids were trasfected into renal cell carcinoma cell line 769-P,and the expression of miR-218 in these cells were detected.Results The plasmids were constructat successfully,which was determind by enzyme digestion and sequencing results.The constructed expression plasmids pcDNA3.1-miR-218 transfection of human renal cell carcinoma cell line 769-P,miR-218 cxpression level of cells was significantly increased after trasfected by recombinant plasmids carrying miR-218 gene (relative expression quantity was 1.64).Conclusion The miR-218 expression plasmids pcDNA3.1-miR-218 were successfully constructed,the plasmids can be applied to the study of miR-218 function and mechanism in renal cell carcinoma.
