CircRNA NRIP1 levels were elevated in PTC tissues and cells. A The expression levels of CircRNA NRIP1 in PTC tissues (
N = 50) and corresponding normal tissues were determined using qRT-PCR. B The expression levels of CircRNA NRIP1 in stage I/II PTC patients and stage III/IV PTC patients via qRT-PCR. C The expression levels of CircRNA NRIP1 in PTC cell lines, including TPC1, B-CPAP, IHH-4 and K1 and the normal thyroid epithelial cell line Nthy-ori3-1 by qRT-PCR. *P < 0.05
