Recently, on the basis of the GEO database, Gu and his colleagues constructed an ARG model consisting of eight genes (BCL2, BIRC5, EIF4EBP1, ERO1L, FOS, GAPDH, ITPR1, and VEGFA), which can be used as an independent prognostic indicator of breast cancer [31]. This evidence concerns the gene BIRC5 and breast cancer.
