BMP7 and melanoma: Bone morphogenetic protein 7 (BMP7) is an integral member of the transforming growth factor-β (TGF-β) superfamily, a 35 kDa homodimeric protein (Ozkaynak et al., 1990; Ducy and Karsenty, 2000), is renowned not just for its role in cartilage and bone formation but also for its influence on mammalian eye development, melanin synthesis, and melanoma genesis (Rothhammer et al., 2005; Vitic et al., 2021).
