Fig. 1. LncRNA ROR is upregulated in PTC tissues and cells and promotes features associated to malignancy in TPC-1 cells.
A LncRNA ROR expression in PTC tissue and adjacent tissue samples of patients with PTC as detected by RT-qPCR, normalized to GAPDH (n = 85). *p < 0.05 vs. adjacent tissues. B LncRNA ROR expression in PTC cell lines TPC-1, BCPAP, IHH4, as well as normal thyroid Nthy-ori 3-1 cell line as detected by RT-qPCR, normalized to GAPDH. *p < 0.05 vs. Nthy-ori 3-1. C LncRNA ROR overexpression and silencing efficiency in TPC-1 cells verified by RT-qPCR. D TPC-1 cell viability after alteration of lncRNA ROR as detected by MTT. E Size and number of colonies in TPC-1 cells after alteration of lncRNA ROR, as detected by colony formation assay. F TPC-1 cell migration and invasion after alteration of lncRNA ROR as detected by Transwell assay (×200). G TPC-1 cell apoptosis after alteration of lncRNA ROR as detected by flow cytometry. *p < 0.05 vs. Nthy-ori 3-1 cells or oe-NC, #p < 0.05 vs. sh-NC. Cell experiments were repeated three times independently.
