SDC1 is a critical transmembrane proteoglycan in breast cancer.

There has been an increasing incidence of breast cancer around the world in recent years. As a burgeoning model of diagnosis and treatment, precision medicine has become a new trend in breast cancer management. Dysregulated glycometabolism is well established as a tumor feature. SDC1 is a glycometabolism-related gene and participates in the progression, metastasis, resistance and recurrence of malignant tumors. SDC1 promotes the development of breast cancer by disturbing tumor stem cell phenotypes, the cell cycle and apoptosis, and then modulates macrophage migration, epithelial-mesenchymal transformation, angiogenesis and the tumor-bone microenvironment. We summarized the recent advances regarding the role of SDC1 in the mechanism driving the occurrence of breast cancer, and evaluated its potential therapeutic contributions.
