Overall, considering both the CCLE and LINCS datasets, eight selenoproteins were overexpressed (DIO2, GPX1, GPX4, SELENOI, SELENON, SELENOS, TXNRD1 and TXNRD3) and five were down-expressed (DIO1, GPX2, GPX3, SELENOP and SELENOW) in TNBC compared to all other “non-TNBC” breast cancer subtypes. Here, SELENOI is linked to breast carcinoma.
