ABSTRACT
Aim ToinvestigatetheeffectsofmiRNA-181 a on breast cancer resistance protein ( BCRP ) . Methods Bioinformaticspredictedbindingsitesof BCRP mRNA-3ˊUTR region and miR-181 a;further lu-ciferase reporter gene analysis confirmed that miR-181 a could combine with BCRP mRNA-3ˊUTR; qRT-PCR and Western blot detected related mRNA and protein expressionlevels.Results Comparedwithnegative transfection group, after the miR-181a mimic and PGL3-BCRP 3ˊUTR were co-transfected, luciferase ac-tivity was significantly decreased ( P 0. 05 ); after transfecting miR-181 a inhibitor for 48h, compared to the negative group, the expression of miR-181 a in MCF-7 cells was reduced (P0.05).Conclusion miR-181acanregu-late BCRP expression by targeting the BCRP mRNA-3ˊUTR region.
