ceRNA-mediated regulatory mechanisms of prognostic genes. (A) mRNA-miRNA-lncRNA regulatory network, where red nodes represent prognostic genes, yellow triangles denote miRNAs targeting prognostic genes, and green squares indicate lncRNAs interacting with miRNAs. (B) TF-mRNA-miRNA regulatory network, with red nodes representing prognostic genes, yellow triangles indicating TFs, and green squares denoting miRNAs. Abbreviations: MDGs: mitochondrial autophagy-related differential genes; OS: osteosarcoma; TF: transcription factor.
