Figure 2.

Expression divergence in pairs of paralogs of different ages. Expression similarity decays steadily over evolutionary time. (a) mRNA data and (b) proteomic data suggest similar trends. Proteomic data [12] are derived from relative antibody staining intensity examined either in tissue sections (tissue microarray (TMA), overall signal; tissue microarray focused (TMAf), focused signal in the staining cell subset) or through cell-line staining cell microarray (CMA). Figure 2a is a box-and-whisker plot, with thick black horizontal lines showing the median, a box drawn between the quartiles, dotted lines extending to the minimum and maximum and outliers illustrated as circles.
