The effect of CEP55 methylation on the OS of various cancers was further explored through the DNMIVD database, and the results showed that CEP55 methylation levels in CHOL, PAAD, PARD, KIRC, KIRP, CESC, and LIHC were significantly and negatively correlated with patient prognosis (Figure 4J). The gene discussed is CEP55; the disease is cancer.
