Briefly, the biomarkers found in the Xpert BC Monitor test are mRNAs translated into proteins that are related to cell pathways such as cell division, adhesion, differentiation, and response to stress (ABL1), cell growth and signal transduction (ANXA10), epigenetic dysregulation in BC (UPK1B), neuroendocrine stress response, immunity, and inflammation (CRH), and proliferation and survival (IGF2) (16). This evidence concerns the gene CRH and breast cancer.
