BAG2 and endometriosis: The results of RT-qPCR (Figure 4A) and Western blot analysis (Figure 4B) showed that the mRNA and protein expression of BAG2 in endometrial tissues from human endometriosis (En-H tissues) and from mouse endometriosis (En-M tissues), as well as in HESCs-En cells, were up-regulated when compared with endometrial tissues from human uterine myomas (Con-H) and from healthy normal mice (Con-M) tissues, as well as in HESCs-NC cells (p < 0.05).
