Proteomics differences in tumor vs stroma. A Proteomics abundance z score for proteins significantly different between the tumor and stroma clusters. B Protein abundance for four proteins that were identified as tumor-epithelial specific in the CPTAC PDAC study. C Protein abundance in tumor vs stroma clusters including proteins annotated as drug targets. D CEACAM1 protein abundance in the samples with a KRAS variant allele frequency increased > 20% in the epithelial-enriched core compared to the stroma-enriched core and bulk tissue. E CPOX protein abundance in the samples with a KRAS variant allele frequency increased > 20% in the epithelial-enriched core compared to the stroma-enriched core and bulk tissue
