Analysis of protein differential expression. a Volcano plot graph illustrating the differential abundant proteins in the quantitative analysis. The − log10 (P value) was plotted against the log2 (ratio cancer/normal). The red dots represented proteins up-regulated in cancer samples, green dots corresponded to proteins down-regulated in cancer samples. b The heat map of significantly different proteins was shown between cancer tissues and adjacent normal tissues. The analysis was achieved by using Morpheus (
