We used microarrays to develop gene signatures for XBP1 and IRE1 in myeloma cells to explore the role of this UPR/differentiation pathway in proteasome inhibitor resistance. RPMI-8226 and JJN3 human myeloma cells were infected with lentivirus expressing non-targeted (NT) shRNA, shIRE1 or shXBP1 and ...
