Abstract
BACKGROUND: Many studies have shown that non-coding RNAs (ncRNAs), including long non-coding RNA (LncRNA) and micro RNA (miRNA), play a crucial regulatory role in glioma. LINC01116 is a newly discovered LncRNA, and the relationship between LncRNA and glioma is still under exploration. METHOD: LncRNAs with potential differences were screened through GEO database, and the expressions of LINC01116 and miR-744-5p/TGF-β1 in glioma tissues were tested using qRT-PCR. Changes in proliferation and migration/invasion of glioma were tested using CCK-8 and transwell assay. The expression changes of TGF-β1 were tested using qRT-PCR and Western blot. Targeted binding among LINC01116, miR-744-5p and TGF-β1 was verified using double luciferase reporter, RNA Immunoprecipitation (PIR) and RNA pull-down experiments. The effect of LINC01116 on tumor growth was determined by tumor allografting test. RESULTS: GEO database and clinical research revealed that the expression level of LINC01116 in glioma increased, and the elevation of LINC01116 was closely related to the adverse prognosis of clinical patients. Functional experiments showed that the inhibition of LINC01116 could up-regulate miR-744-5p-mediated proliferation and metastasis of glioma cells. Western blot analysis and qRT-PCR analysis showed that LINC01116 regulated TGF-β1 by mediating miR-744-5p. Further cell behavior experiments showed that LINC01116 acted as miR-744-5p sponge to inhibit proliferation and metastasis caused by TGF-β1. Finally, the analysis of animal models in vivo showed that LINC01116 could regulate the tumor growth of glioma. CONCLUSION: LncRNA LINC01116 acts as an oncogene and promotes TGF-β1 mediated proliferation and metastasis by acting as competitive endogenous RNA (ceRNA) in glioma. AJTR
