PPARG and breast cancer: The evidence that miR-27b-3p could promote BC growth by inhibiting peroxisome proliferator-activated receptor gamma (PPARG) expression has been experimentally demonstrated in vivo by implanting MDA-MB-231 cells transfected with miR-27b-3p, miR-27b-3p mimics or miR-27b-3p mimics and treated with PPARG agonist [50].
