D, E MAGE-A3/6 protein levels are actively degraded upon nutrient deprivation. HeLa cells were treated for the indicated times with complete media (DMEM + 10% FBS) or EBSS containing 100 µg/mL translation inhibitor cycloheximide (CHX). Protein degradation rates are shown (E). Quantitation represents average of n=3 with standard deviation shown. Data information: Asterisks indicate ** p<0.01. ns indicates p>0.05 using 2-way ANOVA.
