Plasma-targeted proteomic and lipidomic profiling of MASLD, MASH, and hepatitis C virus infection

The results of this research provide value to the field of proteomics as a large-scale, reproducible, and hypothesis-generating plasma dual-omics reference dataset. This study was not designed to establish diagnostic biomarkers, to assess clinical discriminative performance, or to imply causal mechanisms. Instead, by emphasizing reproduciblilty across independent cohorts, we provide a plasma dual-omics reference dataset that captures coordinated immune and lipid metabolic alterations associated with chronic liver disease severity. These data provide a framework and resource for future studies researching risk stratification, therapeutic monitoring, and mechanistic validation in chronic liver disease.
