Macrophage inflammatory protein-1alpha (MIP-1α) is a cytokine with bone-resorbing properties secreted by MM cells and also by other BMM cells [49]; high expression of MIP-1α was found in BM PCs and in the serum of MM patients, and positively correlated with the presence of extensive lytic lesions and increased angiogenesis [50]. The gene discussed is CCL3; the disease is Miyoshi myopathy.
