CD276 and cancer: Hence, the associations between DNA methylation and CD276 expression in different types of cancer were investigated, and the results obtained revealed that the DNA methylation level of CD276 was negatively correlated with CD276 expression in many types of cancer, including BLCA, BRCA, HNSC, KIRP, LUAD, LUSC and TGCT, whereas it was positively correlated with other cancer types, including PCPG.
