Indeed, we showed that SDF1α, released by BMSCs upon MM-derived Jagged stimulation, determines MM cell resistance to the above reported drugs by promoting the expression of Bcl2, survivin and the multidrug resistance-associated protein 1 (MRP1/ABCC1) (Garavelli et al., 2017). The gene discussed is CXCL12; the disease is Miyoshi myopathy.
