Proteome analysis of housekeeping proteins. a The number and percentage of protein quantified in tumor and normal tissues. b Proteins quantified in over 90% of normal and tumor tissues, where 2384 commonly observed proteins were considered as housekeeping proteins. c Gene ontology biological process analysis of the 2384 housekeeping proteins. d A relatively consistent expressional level of ARPC3 across tumor and normal tissues. e A fluctuated expressional level of RNF20 across tumor and normal tissues
