F Knockdown of DCAF12 with individual siRNAs blocks MAGE-A3/6 degradation upon nutrient deprivation. HeLa cells were treated with the indicated siRNAs for 72 hrs before incubation in EBSS for the indicated times. Note, time 0 samples between siRNA groups were normalized to more readily discern differences in MAGE-A3/6 degradation upon nutrient deprivation.
