Our analysis results displayed that promoter methylation levels of LIPT1 were significantly reduced in several tumor tissues, including BLCA, lung squamous cell carcinoma (LUSC), rectum adenocarcinoma (READ), THCA, HNSC, CESC, prostate adenocarcinoma (PRAD), UCEC, LUAD, and KIRP (Figure 5). This evidence concerns the gene LIPT1 and rectum adenocarcinoma.
