For example, MIR647, MIR99AHG, and LINC00472, identified in our differentially methylated analysis, could regulate the progression of oral squamous cell carcinoma, prostate cancer, and lung adenocarcinoma by promoting cell proliferation, migration, epithelial-mesenchymal transition, and other processes [37–40]. This evidence concerns the gene MIR99AHG and oral cavity squamous cell carcinoma.
