ABCB1 and endometrial cancer: As Figure 4B: l–n and Fig. 4C shows, upon administration of the miR‐495 mimic, the apoptosis of the cisplatin‐stressed (cisplatin is not a substrate of MDR1) A2780C cells (an endometrial cancer cell line resistant to cisplatin 15) did not increase or decrease much compared with the cells treated only with cisplatin, and a similar result was observed in cisplatin‐stressed A2780DX5 cells (Fig. 4B: j, k and Fig. 4C), suggesting that miR‐495 is ABCB1 specific.
