1 KCNQ1OT1 contributes to sorafenib resistance and programmed death-ligand-1-mediated immune escape via sponging miR-506 in hepatocellular carcinoma cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
2 The aim of the present study was to investigate the role of KCNQ1OT1 in sorafenib resistance and immune escape of HCC cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
3 KCNQ1OT1 and PD-L1 were found to be upregulated and miR-506 was downregulated in sorafenib-resistant HCC tissues and cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
4 Furthermore, KCNQ1OT1 knockdown reduced the IC50 value of sorafenib, suppressed cell metastasis and promoted apoptosis in sorafenib-resistant HCC cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
5 Furthermore, KCNQ1OT1 knockdown reduced the IC50 value of sorafenib, suppressed cell metastasis and promoted apoptosis in sorafenib-resistant HCC cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
6 Moreover, KCNQ1OT1 knockdown changed the tumor microenvironment and T-cell apoptosis in a sorafenib-resistant HCC/T-cell co-culture model. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
7 In addition, it was demonstrated that KCNQ1OT1 functioned as a competing endogenous RNA of miR-506 and increased PD-L1 expression in sorafenib-resistant HCC cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
8 miR-506 inhibition abolished the effects of KCNQ1OT1 knockdown on sorafenib sensitivity, tumor growth, the tumor microenvironment and T-cell apoptosis. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
9 In conclusion, KCNQ1OT1 knockdown inhibited sorafenib resistance and PD-L1-mediated immune escape by sponging miR-506 in sorafenib-resistant HCC cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
10 In conclusion, KCNQ1OT1 knockdown inhibited sorafenib resistance and PD-L1-mediated immune escape by sponging miR-506 in sorafenib-resistant HCC cells. Sorafenib KCNQ1 opposite strand/antisense transcript 1 Homo sapiens
