A, Schematic representation of Hsp70 and Hsp90 machineries. B, Cartoon representation of polysome profiling. C, qPCR analysis of HSPA8 mRNA upon Rapalink-1 and Rapamycin treatment, isolated from 10% - 50% sucrose gradient fractions. Pooled fractions corresponding to free ribosomal subunits and messenger ribonucleoprotein (mRNPs) (Free/mRNPs), low-molecular-weight polysomes (Low Poly), and high-molecular-weight polysomes (High Poly) are displayed. A two-way ANOVA test was performed to determine statistical significance (n = 3). D, Western blot analysis of translationally regulated endogenous proteins upon treatment. All values represent the mean + SEM. *p < 0.05, **p < 0.01
