Polysome profiles of aptamer-containing mRNA indicate regulation is independent of translation initiation. (a) Polysomes were fractionated from yeast expressing both TetR and a 5-1.2-containing vYFP reporter mRNA, which were grown in the absence or presence of Dox. Polysome profiles for both the − Dox and + Dox growth conditions are shown. (b) qPCR measurements of the relative amounts of reporter mRNA within each polysome fraction, both for the − Dox and + Dox conditions. (c) qPCR measurements of relative amount of ACT1 mRNA in each polysome fraction, under − Dox and + Dox conditions. For both (b) and (c) error bars indicate the range of values for technical replicates. The data are representative of two independent, biological replicates.
