Upamostat potentiates bortezomib cytotoxicity and delays proteasome recovery in bortezomib-resistant malignant lymphoma cells through modulation of the DDI2/NRF1 axis.
Findings identify UMS as a candidate DDI2/NRF1-axis modulator that potentiates BTZ-induced cytotoxicity and delays functional proteasome recovery in BTZ-resistant malignant lymphoma cells.
