Bortezomib and KPT330 enhance apoptosis in HCT116 and RKO cells. A, HCT116 and RKO cells were treated with bortezomib, KPT330, or their combination for 48 hours at the indicated concentrations. The cells were subsequently stained with Annexin V, apoptotic cells were distinguished by flow cytometric analysis. B, Measurement of caspase-3 and -7 by means of a luminometric assay was performed in cells receiving the same treatment.

(D)Western blot analysis of RNF146 in cytoplasmic and nuclear fraction after KPT-185 treatment. Data represented mean ± s.e.m., n = 5; *P < 0.05, **P < 0.01. NES, nuclear export signal.

a. Cell growth of ARID1A-wildtype RMG1 cells transfected with ARID1A and non-target siRNA for 24 h and treated with piperlongumine for 72 h. b. Apoptosis of RMG1 cells after transfection and treatment as described in a as measured using annexin-V and PI staining. c. Cell growth of RMG1 cells transfected and treated with 5 μM of piperlongumine as described in a, but in the presence or absence of the antioxidant NAC. Cell growth was measured using the WST-1 assay and quantified relative to DMSO treated non-target control. *P < 0.05; **P < 0.01; ***P < 0.001.
