Identification of microbial species and proteins associated with colorectal cancer by reanalyzing CPTAC proteomic datasets

This study reanalyzed CPTAC colorectal cancer proteomics data using a custom metaproteomics pipeline to identify microbial species and proteins differentially abundant in tumor and normal tissues. It shows that microbial features, particularly from multiplexed data, can support tumor classification and may complement human biomarkers in colorectal cancer research.
