A, qRT‐PCR result showed that NR2F1‐AS1 was significantly increased in thyroid cancer (TC) tissues compared with adjacent normal tissues; (B) The expression of NR2F1‐AS1 was significantly up‐regulated in TC cell lines, FTC‐133 and B‐CPAP, compared with normal human thyroid cell line Nthy‐ori 3‐1; (C,D) Silence of NR2F1‐AS1 significantly down‐regulated the expression of NR2F1‐AS1 in FTC‐133 cells and B‐CPAP cells compared with negative control (NC) group, which indicated that the transfection in this study was successful; (E,F) Knockdown of NR2F1‐AS1 significantly suppressed cell viability rate in FTC‐133 cells and B‐CPAP cells compared with NC group. *P < 0.05, **P < 0.01
