摘要： Stropharia rugosoannulata mushroom peptides have well-defined sequences, specific structures, and excellent antihypertensive activity. In this study, metabolomic and proteomic analyses revealed the antihypertensive mechanism of mushroom-derived protein-peptides, GQEDYDRLRPL (GL-11P) and KSWDDFFTR (KR-9P), to demonstrate their potential antihypertensive buck-regulation systems and pathways. Protein-peptides were predominantly down-regulated expression of endogenous metabolites in antihypertensive regulation, and bile acid analogs were key endogenous differentially expressed metabolic markers. Antihypertensive treatment with protein-peptides activated the immune and signal transduction systems, affected extracellular regions, metal ion binding, and receptor binding ability. The ECM-receptor interaction pathway, with differentially expressed proteins in antihypertensive treatment, distinguished the protein-peptides from blank control and was also a critical pathway that distinguished the two protein-peptides. Up-regulatory pathways of protein expression dominated by GL-11P's antihypertensive regulation, while down-regulatory pathways of protein expression dominated by KR-9P's antihypertensive regulation. Protein-peptides exerted antihypertensive regulatory effects by enhancing immune responses, up-regulating protein and enzyme binding capacity, and down-regulating inflammatory mediator release. Differentially expressed protein interactions produced in protein-peptides antihypertensive therapy mostly up-regulated the Reactome pathway and were dominated by immune system regulation. This study provided data support for utilizing mushroom-derived protein-peptides in antihypertensive therapy, and enriched the theoretical basis of protein-peptides' antihypertensive regulation mechanisms.
