CircLDLR Promotes Papillary Thyroid Carcinoma Tumorigenicity by Regulating miR-637/LMO4 Axis

<div>CircLDLR functions as an efficient miR-637 sponge in PTC cells. (a) Potential binding sites of circLDLR in miR-637 sequences. (b, c) Interaction analysis between circLDLR in miR-637 in TPC-1 and IHH-4 cells using the dual-luciferase reporter assay and RIP assay. (d) qRT-PCR analysis of miR-637 expression in TPC-1 and IHH-4 cells transfected with circ-NC, circLDLR, si-circLDLR, or si-NC. (e) Levels detection of miR-637 in 45 PTC tissues and matched normal tissues with qRT-PCR. (f) The correlation analysis between circLDLR and miR-637 using Pearson correlation analysis. (g) qRT-PCR analysis of miR-637 expression in PTC cell lines (TPC-1 and IHH-4) and normal Nthy-ori 3-1 cell lines. <span class="nowrap"><svg height="10.7395pt" id="M62"
