The functions of the differentially expressed ubiquitination of CRC cells versus normal cells. A The numbers of differentially ubiquitinated proteins and sites of CRC cells versus normal cells (fold change > 1.5, and the ubiquitination solely detected in cancer samples or normal adjacent samples were also included). (B–D) The GO enrichment of all differentially ubiquitinated proteins. E The KEGG enrichment of all differentially ubiquitinated proteins. F Functional enrichment of secretory proteins having differentially-expressed ubiquitination, as analyzed using the Metascape database. G The cellular sources of secretory proteins having differentially-expressed ubiquitination, as analyzed using the PaGenBase database
