Abstract: Breast cancer is a disease that seriously endangers women's physical and mental health.The death of patients with advanced breast cancer is largely due to distant metastasis of important organs rather than primary tumors.Jagged1(JAG1),as one of the important ligands of the Notch signaling pathway,is not only expressed in tumor cells but also expressed in cells in the tumor microenvironment.By activating the Notch signaling pathway,it promotes the aggressive progression and distant metastasis of breast cancer.This paper comprehensively discusses the location of the JAG1 gene and the structure of the JAG1 protein,the mechanism of JAG1 promoting distant metastasis of breast cancer,the mechanisms of JAG1 promoting breast cancer distant metastasis,brain metastasis,and bone metastasis as well as JAG1 targeted therapy.

Key words: Jagged1(JAG1), Breast cancer, Distant metastasis, Targeted therapy
