To investigate whether LMX1A, SOX1, and ZNF177 were aberrantly methylated in CRC, we used the data of the Infinium Human Methylation 450K BeadChips from the MethHC database to analyze the methylation levels of LMX1A (NM_001174069), SOX1 (NM_005986), and ZNF177 (NM_003451) in 369 tissue samples from colon and rectal adenocarcinoma patients (Figure 1A). Here, SOX1 is linked to rectum adenocarcinoma.
