MPM cells with low ER stress/UPR signalling are intrinsically resistant to chemotherapy. a, b Viability (a) and IC50 (b) of MPM lines and normal mesothelial cells (Met-5A) after treatment with bortezomib for 72 h. Data are presented as mean ± s.d. (n = 3). c Clonogenic assay of MESO-4 and BE261T cells treated with the indicated doses of bortezomib. d Immunoblots of MESO-4 and BE261T cells for proteins involved in the UPR and apoptosis. e Viability of MESO-4 and BE261T cells after treated with cisplatin/MTA for 72 h
