Fig. 4. The effects of TRAF6 on colony and apoptosis of MM cells. (A-B) The colony formation assay results revealed that overexpression of TRAF6 promoted the colony formation of cells. (C-D) The apoptosis assay results showed that overexpression of TRAF6 reduced the apoptosis of cells. **p < 0.001 vs. MC+NC; ##p < 0.001 vs. MC+TRAF6; ^^p < 0.001 vs. mimic+NC.
