FOXM1 and breast carcinoma: After successful co-transfection of the plasmids containing miR-671-5p and FOXM1 3′UTR wild type sequence into breast cancer cells, luciferase activities were significantly decreased in miR-671-5p transfected MDA-MB-231 cells compared with the cotransfection of those containing either miR-671-5p /FOXM1 3′UTR mutant sequence or scrambled control/FOXM1 3′UTR wild type sequence.
