c‐met signaling is frequently activated in relapsed and resistant MM, where it plays an important role in induction of BTZ resistance.27 To assess the feasibility of combining SL1 and BTZ, MM.1S and ARP‐1 cells were treated with different concentrations of SL1 alone, BTZ alone or a combination of SL1 and BTZ for 24 hours. The gene discussed is CASC3; the disease is Miyoshi myopathy.
