This study demonstrated that lncRNA CRNDE is a potential diagnostic and prognostic biomarker for osteosarcoma (OS). The lncRNA CRNDE/miR-335-3p axis was found to play a role in OS progression, with lncRNA CRNDE promoting cell proliferation, migration, and invasion while inhibition of miR-335-3p had the opposite effect.
Background: This study was performed to evaluate the diagnostic and prognostic value, as well as the role of long-chain noncoding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) in osteosarcoma (OS). Materials and Methods: A quantitative real-time polymerase chain reaction assay was to determine lncRNA CRNDE and microRNA-335-3p (miR-335-3p) expressions. The Kaplan-Meier analysis was to analyze the relationship between lncRNA CRNDE expression and survival in patients with OS. Receiver operating characteristic curves were to evaluate the diagnostic value of lncRNA CRNDE in OS. Bioinformatics analysis and luciferase reporter assays were used to predict and confirm the relationship between lncRNA CRNDE and miR-335-3p. Cell counting Kit-8 and transwell migration assays assessed the role of lncRNA CRNDE and miR-335-3p in OS cells. Results: lncRNA CRNDE expression was upregulated and miR-355-3p expression was downregulated in OS. In patients with OS, low lncRNA CRNDE expression demonstrated higher overall survival, whereas high lncRNA CRNDE expression was an independent poor prognostic factor. Furthermore, increased lncRNA CRNDE expression was associated with distant metastasis and the tumor-node-metastasis stage in patients with OS, which can be considered as an independent diagnostic biomarker in OS. We revealed that miR-335-3p was the target of lncRNA CRNDE. It also demonstrated that knockdown of lncRNA CRNDE inhibited OS cell proliferation, migration, and invasion, and inhibition of miR-355-3p promoted this effect. Finally, miR-335-3p partially mediated the stimulatory effects of lncRNA CRNDE in OS. Conclusion: We demonstrated that lncRNA CRNDE is a potential diagnostic and prognostic biomarker for OS, and the lncRNA CRNDE/miR-335-3p axis participates in OS progression.
