Interestingly, a recent study showed that BMP7 significantly inhibited the TGF-β1-activated epithelial-mesenchymal transition (EMT)-related genes in breast cancer cells, resulting in a significant reduction in TGF-β1-triggered cell growth and cell metastasis, suggesting that the BMP7 signalling axis could be a promising pathway for therapeutic intervention in breast cancer [30]. Here, BMP7 is linked to breast cancer.
