The transfection efficiency of PGC-1β and FOXA2 were detected in MCF-7 and MDA-MB-231 cells. a, b The transfection of PGC-1β interference and overexpression vectors were detected in MCF-7 and MDA-MB-231 cell lines by qRT-PCR. c, d The transfection of FOXA2 interference and overexpression vectors were detected in MCF-7 and MDA-MB-231 cell lines by qRT-PCR. e, f The protein expression levels of PGC-1β and FOXA2 were detected by western blot. All bar graphs depicted quantification of triplicate results with mean ± SD. *P < 0.05, **P < 0.01
