Collagen type I alpha 1 (COL1A1), a member of the collagen family, is involved in epithelial-mesenchymal transition, which is closely linked to malignant tumorigenesis. COL1A1 is highly expressed in various cancers and regulates various cellular processes, including cell proliferation, metastasis, apoptosis, and cisplatin resistance. COL1A1 is also associated with cancer progression and prognosis; elevated COL1A1 expression is associated with poor prognosis in cancer patients. However, the main role of COL1A as a cancer-promoting factor in specific tumors has not been reported. Additionally, the protein levels and mechanisms of action of this protein differ among tumor types. This review discusses current research progress concerning COL1A1 in different tumor types, and then summarizes its contributions to cancer progression, thus providing a basis for follow-up research and potential targets for cancer treatment.
