Their results also indicated that changes in the epithelial‐mesenchymal transition process of CXCR7 bladder cancer are caused by the activation of the AKT and ERK signaling pathways.14 It is likely that CXCR7 may also exert a significant effect in the progression of other malignant tumors. The gene discussed is AKT1; the disease is urinary bladder carcinoma.
