Confirmation of actinomycin D as an active compound. (A) Authentic actinomycin D (Sigma #A12110) improved growth of yeast expressing ΔProQ103. Results are representative of experiments performed in triplicate. Uninduced cells were grown in 4% raffinose. (B) Actinomycin D blocked the formation of puncta in cells expressing Q103-GFP. Representative images are shown, with puncta indicated by white arrows. Scale bar is 2 μm. For quantifications, more than 200 yeast cells were examined and scored for the presence of puncta.
