EXO1 and invasive breast carcinoma: The results showed negative correlation between the methylation of five specific CpG sites (cg03292648, cg07639959, cg17423498, cg17736920, cg21919602) and EXO1 gene expression in BRCA, three CpG sites (cg03292648, cg12401425, cg21919602) and EXO1 gene expression in THCA; one CpG site (cg03292648) negatively and one CpG site (cg06713297) positively correlated with EXO1 gene expression in UCEC; one CpG site (cg21919602) negatively correlated with EXO1 gene expression in OV; one CpG site (cg06713297) positively correlated with EXO1 gene expression in UCS (Figure 6B).
