Cotreatment of ASA and BTZ reduces the proliferation of myeloma cells. (A) MM1.S cells and (B) RPMI-8226 cells were treated with ASA alone, BTZ alone and ASA+BTZ for 24, 48 and 72 h, respectively. At each time point, the cell proliferation was determined using Cell-Counting Kit-8 analysis. Data are presented as the mean + standard deviation from independent experiments. *P<0.05. ASA, aspirin; BTZ, bortezomib.
