Immunohistochemical analysis was performed to evaluate the expression of vimentin, BMP-2, BMP-4, RANKL, Runx2, OPN, PTX3, and SDF-1, while Kaplan—Meier plots were used to assess their prognostic impact on overall survival in a dataset of 2976 breast cancer patients. The gene discussed is BMP2; the disease is breast carcinoma.
