Targeting TLR4 signaling and proteasome activities resensitized to BTZ myeloma PCs cells from refractory patients. CD138+ cells obtained from refractory MM patients were treated with BTZ (5 nM) in combination or not with TAK-242 (10–20 µM). (A) The percentage of CD138+/annexin V+/7-ADD+ or CD138+/7ADD+ cells were estimated by flow cytometry 48 h post-treatment. (B) Mitochondrial membrane potential was assessed 24 h post-treatment analyzing MFI of DiOC2(3) staining on CD138+ cells by using flow cytometry. Bars indicate the standard error means. * p < 0.05; ** p < 0.01; *** p < 0.001.
