DEPs distribution and expression levels in samples. (A) The x-axis shows the pairwise comparisons of the five sample groups (days 3, 6, 9, 12, and 16), and the y-axis displays the number of proteins. Red and green bars indicate up-regulated and down-regulated proteins, respectively. (B) Venn analysis of DEPs in the five samples (Adapted from Chen et al. [48]). The numbers denote the amount of proteins that were expressed in each class, with arrows indicating the number of up-regulated (↑) or down-regulated (↓) proteins. Classes are labeled from a to o based on the following representations: (a) exclusively expressed in group d6 vs. d3; (b) exclusively expressed in group d9 vs. d3; (c) exclusively expressed in group d12 vs. d3; (d) exclusively expressed in group d16 vs. d3; (e) only expressed in group d6 vs. d3 and d9 vs. d3; (f) only expressed in group d6 vs. d3 and d12 vs. d3; (g) only expressed in group d6 vs. d3 and d16 vs. d3; (h) only expressed in group d9 vs. d3 and d12 vs. d3; (i) only expressed in group d9 vs. d3 and d16 vs. d3; (j) only expressed in group d12 vs. d3 and d16 vs. d3; (k) exclusively not expressed in group d16 vs. d3; (l) exclusively not expressed in group d12 vs. d3; (m) exclusively not expressed in group d9 vs. d3; (n) exclusively not expressed in group d6 vs. d3; (o) expressed in common. (C) Expression profiling of DEPs common among all the samples. The first 7 proteins were down-regulated with log2-transformed fold-change ratios that were no more than 0.5. The other proteins were up-regulated by no less than 1.5-fold. Note: It should be noted that all the redundant proteins were included in the Venn analysis.
