This research aims to explore the interactions between polyunsaturated fatty acids and inflammatory proteins in relation to lung function.
Evaluated spirometric, proteomic, and PUFA biomarker data from 3727 participants in the COPDGene Study.
Used robust linear regression to measure PUFA-protein interactions with FEV1 and conducted mediation analysis for key proteins.
Proteomic data assessed through a 5K aptamer-based assay measuring 4979 SOMAmers.
Identified nine significant PUFA-protein interactions affecting FEV1, notably for the omega 6:3 ratio.
Negative effects observed for seven proteins including PAPP-A, while two proteins exhibited positive interactions.
Mediation analysis highlighted PAPP-A as significant, influencing 10% of the adverse effects from higher omega 6:3 ratios on FEV1.
