BACKGROUND/AIM: We previously reported that Pyra-Metho-Carnil (PMC) suppresses macrophage differentiation in co-culture with mutant (mt) Kirsten rat sarcoma (KRAS) tumors. In this study, we used integrative proteomics and identified a KRAS-regulated membrane and exosomal protein, 5'-nucleotidase ecto (NT5E)/CD73, as a key candidate linking KRAS signaling to macrophage-associated tumor immune microenvironment...
