Comparative multi-omics analysis reveals distinct lipid metabolites and immune proteins in native versus commercial pig breeds, highlighting molecular pathways underlying disease resistance.

Key Points

Investigate the molecular mechanisms driving superior disease resistance in Chinese native Min pigs compared to Large White pigs through integrated serum metabolomics and proteomics.
Analyzed serum from 6 disease-resistant Min pigs and 6 susceptible Large White pigs raised under identical environmental conditions using untargeted metabolomics and proteomics.
Identified candidate biomarkers using ensemble feature selection machine learning, weighted gene co-expression network analysis, quantitative trait locus (QTL) co-location, and parallel reaction monitoring validation.
Identified 62 differentially expressed serum metabolites, with network analysis isolating 4 key phosphatidylcholines significantly associated with cytokine levels and breed type.
Identified 15 proteins significantly correlated with cytokines and unsaturated fatty acid metabolites, with 13 co-localizing to immune or PUFA QTLs and 7 co-localizing to both, including PSMB8, MBL1, and IL1RAP.
