ABSTRACT
Objective To investigate the expression of LncRNA TCONS_00003757 in papillary thyroid carcinoma ( PTC) , and to explore the effect of LncRNA TCONS_00003757 on the proliferation, migration, and invasion in TPC-1 cells. Methods Sixty cases of papillary thyroid carcinoma specimens and paired normal tissues were collected after surgery from October 2017 to March 2018 in the Tangshan Workers Hospital. Real-time PCR analysis was used to examine the expression level of LncRNA TCONS_00003757 in PTC tissues, and the association of LncRNA TCONS_00003757 expression levels with the clinicopathological data of patients was analyzed. The effects of LncRNA TCONS_00003757 and ST3GAL5 silencing on the proliferation, migration, and invasion in TPC-1 cells were assessed by MTT, scratch test, and transwell assay. Protein expression of ST3GAL5 was detected by Western blot after LncRNA TCONS_00003757 silencing. Results LncRNA TCONS_00003757 expression was increased in PTC tissues compared with that in normal tissues ( P<0. 05 ) , which was correlated with capsule invasion and lymph node metastasis( P<0.05) . LncRNA TCONS_00003757 expression in TPC-1 cells was higher than that in normal thyroid follicular epithelial Nthy-ori 3-1 cells(P<0.05). LncRNA TCONS_00003757 and ST3GAL5 silencing inhibited the proliferation, migration, and invasion of thyroid cancer TPC-1 cells, and ST3GAL5 expression was decreased after LncRNA TCONS_00003757 silencing (P<0.05). Conclusion LncRNA TCONS_00003757 expression in PTC is significantly increased and correlated with its occurrence and development. Silencing LncRNA TCONS_00003757 may inhibit the proliferation, migration, and invasion of thyroid papillary cancer cells via decreasing ST3GAL5 expression.
