Changes in mRNA and protein abundances are strongly correlated for metabolic genes.

<p>A) Shown are the coefficients of determination for mRNA fold-change – protein fold-change correlations; black: with all proteins measured in each of the datasets, gray: only with metabolic proteins. <i>P-</i>values denoting the significance of the improved correlations for metabolic genes were estimated based on random sampling from the set of measurements including all proteins. B) Distributions of <i>P</i>-values obtained for 1^st degree CoCCoA analysis while accounting for the variability in the correlations between the mRNA and protein fold-changes.
