To further investigate the role of BMP8A in bone metastasis, a common complication of BC, particularly within TNBC subtype, this study examined the correlations between BMP8A and key biomarkers associated with bone metastases, including osteoblastogenesis, osteoclastogenesis, homing, immuno-escape, and angiogenesis in TCGA-BRCA cohort. Here, BMP8A is linked to breast cancer.
