As a result, some potential biomarkers, including casein kinase 1 epsilon (CSNK1E), p53 (TP53), cell division cycle 25C (CDC25C), annexin A11 (ANX11), eukaryotic translation initiation factor 4E (EIF4E) and mitogen-activated protein kinase 7 (MAPK7), were successfully identified to have increased expression levels in breast cancer. This evidence concerns the gene MAPK7 and breast carcinoma.
