MGAT3 and breast carcinoma: Since recent genomic and transcriptomic data of basal-like breast cancers suggest a close molecular relation to HGSOC [27], we further analyzed MGAT3 expression in the TCGA breast cancer dataset (n = 514) and compared basal-like (n = 98), HER2-enriched (n = 58), luminal A (n = 231) and B (n = 127) types of breast cancers.
