Redox homeostasis modulates the sensitivity of myeloma cells to bortezomib.

The use of proteasome inhibitors have been a major advance in the treatment of multiple myeloma (MM), but their mechanisms of action remain largely unclear. A better understanding of the cellular events downstream of proteasome inhibition is essential to improve the response and identify new combination therapies for MM and other malignancies. This study analysed the relationships between redox homeostasis and bortezomib treatment in MM cells.
