I want to overexpress a number of miRNAs in Lncap cells, I prefer to use a non-commercial and non-viral vector.
You could use a p.cDNA (go to addgene) type of vector and insert there the sequence coding your pre-miRNAs (+ a flanking region).
suppose I have a piggyback vector with this sequence: (5'-pB--promoter--chimeric intron--GFP-?-polyA--pB-3') now I want to express a premiRNA gene beside the gfp protein with same promoter and...
