Specially, seven ECM genes specific to mesenchymal subtype (CMS4), including PI16+ fibroblast-related 4 genes (SFRP2, PRELP, OGN, SRPX) and desmoplastic fibroblast-related 3 genes (THBS2, CTHRC1, BGN), showed a significant association with poorer survival in patient with CRC. Here, OGN is linked to colorectal carcinoma.
