However, the functions and underlying mechanisms of LINC00665 in gastric cancer (GC) remain unclear.Materials and methods: We recruited 49 paired GC tissue to explore LINC00665 expression by qRT-PCR. In vitro function assays were used to explore the roles of LINC00665 in GC progression. Moreover, the interaction among LINC00665, miR-149-3p and RNF2 was explored by bioinformatics analysis and luciferase reporter assay.Results: In the present study, we found that LINC00665 expression was significantly elevated in GC tissues and cell lines. High LINC00665 expression was associated with TNM stage, histological grade, and poor prognosis of GC patients. Function assays showed that LINC00665 suppression significantly reduced GC cells viability and invasion ability in vitro. Mechanistic analysis showed that LINC00665 might serve as a ceRNA for miR-149-3p to regulate the expression of RNF2.Conclusion: Our current study revealed the LINC00665/miR-149-3p/RNF2 axis was involved in GC progression, providing novel insights into the treatment for GC.Keywords: gastric cancer, LINC00665, miR-149-3p, RNF2https://www.dovepress.com/long-non-coding-rna-linc00665-gastric-cancer-tumorigenesis-by-regulati-peer-reviewed-article-OTTgastric cancerLINC00665miR-149-3pRNF2 |
