Comparison of the differentially expressed proteins (DEPs) from four labeled samples. (a) Volcano plots of the DEPs. Each point in the volcanic map represents a protein; the abscissa represents the logarithmic value of the expression of a certain protein in the two samples. The red points represent upregulated DEPs, the green points represent downregulated DEPs, and the black dots represent nondifferentially expressed proteins. (b) Hierarchical clustering heat maps of the DEPs. The expression of each protein is illustrated in red and green to indicate high and low expression, respectively. TP = Tibetan pig (n = 10); YP = Yorkshire pig (n = 10)
