Similarly, MZB caused accumulation of Cyt C and Smac in the cytosol of multiple myeloma cells [30], whereas lymphocytic leukemia cells and cervical cancer cells exposed to bortezomib and delanzomib showed marked overexpression of Noxa, which contributed to the apoptotic death of these cells [37,38]. The gene discussed is PMAIP1; the disease is plasma cell myeloma.
