1, DNAm alterations that have been shown to be associated with poor overall survival in lung adenocarcinoma (LUAD) patients.46 This discovery was followed by cg01525538, cg10954469, and cg13307880, which displayed hypermethylation in tumors across 21 cancer types and were located within the gene-body regions of previously reported cancer-related genes, DUSP5P1, LINC01143, and the PCDH gene cluster.47–49. Here, LINC01143 is linked to lung adenocarcinoma.
