Bioinformatic analysis of the BIRC family gene expression results obtained from The Cancer Genome Atlas (TCGA) showed, similarly to our study, an increase in the expression level of the BIRC5 and BIRC7 genes, and a decrease in the expression level of the BIRC1, BIRC4, and BIRC6 genes in breast cancer [15]. This evidence concerns the gene NAIPP2 and breast cancer.
