Figure Lengend Snippet: (A) Diagram of sucrose gradient fractions used for heavy polysome analysis. (B) qPCR of candidate transcripts in the heavy polysome fraction (≥3 ribosomes per transcript), normalized to 28S rRNA (n = 3; mean ± SD). (C) Schematic of RPA calculation. Polysome association (PA = Heavy/Input) is computed per condition; RPA = PA dTAG /PA DMSO , reported as log₂(RPA). Heatmap shows gene classification across replicates. (D) Correlation between qPCR fold change and RNA-seq–based log₂RPA for 13 validated transcripts spanning the sensitivity spectrum (n = 3; mean ± SD).
