Identification and quantitation proteomic analysis results. A Unique peptide number distribution. The X-axis indicates the unique peptide number of each protein and the Y-axis indicates the corresponding protein number. Most of the identified proteins contain less than 10 peptides and protein quantity becomes less with the increase in peptide number. B Number of significantly differential expressed proteins. Totally 435 proteins were defined to be significantly different, among which 285 were up-regulated and 150 were down-regulated. C Volcano plot of log2 fold-change (X-axis) versus -log10 Qvalue (Y-axis, indicating the probability that the protein is differentially expressed). Red dots represent proteins significantly up-regulated, green for significantly down-regulated, and gray for no-significant change
