Given the intrinsic genetic heterogeneity of CRCs, the relative expression of both YY1 and BCL2L15 was analyzed within the GSE35896 dataset (Wessels, 62 primary CRC samples), with samples stratified based on their molecular types associated with a gene expression signature of epithelial-mesenchymal transition (EMT; Figure 6C). This evidence concerns the gene BCL2L15 and colorectal carcinoma.
