LINC00958/miR‐627 signal axis regulates the proliferation, migration, and invasion of thyroid papillary carcinoma cells by TRIM44

Papillary thyroid cancer (PTC) has attracted much attention due to its high morbidity and severe metastasis. Long noncoding RNA ENST00000504230 (LncRNA ENST00000504230, known as LINC00958) was overexpressed in many cancers and associated with cancer development. However, its underlying mechanism in...

Description
Summary:Papillary thyroid cancer (PTC) has attracted much attention due to its high morbidity and severe metastasis. Long noncoding RNA ENST00000504230 (LncRNA ENST00000504230, known as LINC00958) was overexpressed in many cancers and associated with cancer development. However, its underlying mechanism in PTC remains unclear. PTC tissues and corresponding adjacent tissues were collected for measuring the expression of LINC00958 and miR‐627. MiR‐627 and TRIM44 expressions were measured in in vitro cultured PTC cell lines (B‐cpap and IHH4 cells) transfected with sh‐LINC00958 or miR‐627 mimic using RT‐qPCR and western blot. Cell proliferation, migration, and invasion were measured by 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl‐tetrazolium bromide (MTT) and Transwell assays, respectively. Dual‐luciferase reporter assay was performed to evaluate the target association between miR‐627 and TRIM44. LINC00958 was up‐regulated in PTC tissues and cells, while the expression of miR‐627 was lowly expressed. Knockdown of LINC00958 inhibited the proliferation, migration, and invasion by elevating miR‐627 expression in PTC cells. TRIM44 was confirmed as a target of miR‐627. Overexpression of miR‐627 in PTC inhibited the proliferation, migration, and invasion by down‐regulating the expression of TRIM44. LINC00958 promoted proliferation, migration, and invasion in PTC by down‐regulating miR‐627 and activating TRIM44, indicating the potential therapeutic effect of LINC00958 on PTC.
