Induction of Apoptosis Coupled to Endoplasmic Reticulum Stress through Regulation of CHOP and JNK in Bone Marrow Mesenchymal Stem Cells from Patients with Systemic Lupus Erythematosus
Figure 3
Intervention to ERS can partly rescue the apoptosis of BM-MSCs from SLE patients. BM-MSCs of SLE patients and normal controls were treated with (+) or without (−) 4-PBA (100 μM) from the same time point for the indicated time. (a) Cell viability was assessed by FCM analysis. (b) Cell lysates were analyzed for the levels of p-IRE-1, p-PERK, BAX, Bcl-2 and cleaved caspase-3 via western blot. (Bar represents mean ± SD, compared with the normal group, # compared with the SLE group). (c) Immunofluorescence analysis was used to analyze the level of cleaved caspase-3.
