Abundance changes of proteasome proteins and their transcripts during aging. Members of the 19S and 20S complex are displayed separately and changes are shown for both the age comparisons as box plots. Transcripts are displayed as light blue and proteins as dark blue boxes. Changes of individual proteins are displayed as dots, orange dots represent significant cases (adj. p < 0.05, n=4 per age group for proteome and n=5 per age group for transcriptome). In boxplots, the horizontal line represents the median, the bottom and top of the box the 25th and 75th percentile, respectively, and the whiskers extend 1.5 folds the interquartile range.
