ABCC1 and lung adenocarcinoma: KCNQ1OT1 acted as a potential oncogene that inhibited the malignancy and chemoresistance of lung adenocarcinoma cells,22 and Huiqin Hu et al also indicated that KCNQ1OT1 modulated oxaliplatin resistance in hepatocellular carcinoma through the miR‐7‐5p/ABCC1 axis.23 Furthermore, Zhang et al reported that knockdown of KCNQ1OT1 inhibited tongue squamous cell carcinoma cell proliferation and cisplatin resistance.24
