As LY6G6D and FUT4 tended to be upregulated in MSS (typically poorly immunogenic), but not in MSI (typically highly immunogenic) CRC cell lines, we then analyzed other primary tumours by using GSE13294 [22] and GSE30540 [23] datasets, where MS status and chromosomal instability were available. Here, FUT4 is linked to colorectal carcinoma.
