Methods: The gene expression and related clinical data of OS patients were extracted from TCGA database, and prognostic related DRLs genes were screened to construct a prognostic model. The expression of related DRLs in cells and tissues was detected by qRT-PCR. The effect of si-ASB16.AS1 on the proliferation of MG-63 cells was detected by CCK-8 assay. Kaplan-Meier method was used to draw the survival curve, and Cox regression was used to analyze the factors affecting the prognosis of patients with OS. Results: Six prognostic related DRLs (RP11.304F15.6, RP11.750H9.5, RP11.313F23.4, RP11.46C2.47, ASB16.AS1, and RP11.452C13.1) were selected for constructing a prognostic model. ROC analysis showed that the model had a strong predictive ability. qRT-PCR analysis showed that the expression of six DRLs was up-regulated in OS cell lines, and si-ASB16.AS1 inhibited the proliferation of MG-63 cells. The overall survival time of OS patients with high ASB16.AS1 expression is significantly shorter than that of patients with low ASB16.AS1 expression. Conclusion: 6 DRLs were identified as prognostic markers of OS, and a valuable prognostic model of OS was constructed. It was found that ASB16.AS1 can participate in the proliferation of OS cells and is an independent prognostic biomarker in patients with OS.展开更多
