According to other studies, lncRNA KCNQ1OT1 located on human chromosome 11p15.5 has a close relationship to proliferation and drug resistance of lung cancer, and lowering its expression can remarkably enhance drug resistance of lung cancer to chemotherapeutic drugs (Du, Zhou, Beatty, Weksberg, & Sadowski, 2004; Ren, Xu, Huang, Zhao, & Shi, 2017). This evidence concerns the gene KCNQ1OT1 and lung cancer.
