Multi-Omics Elucidation of Edulinine's Intervention Mechanism in Hypertensive Rats

Area of Science:

• Cardiovascular Research
• Molecular Pharmacology
• Metabolomics and Proteomics

Background:

• Hypertension involves vascular dysfunction and target organ injury.
• Edulinine (Edu) is a potential antihypertensive agent with unclear mechanisms.
• Vascular endothelial injury is a key factor in hypertension.

Purpose of the Study:

• Investigate the protective effects of Edu on vascular endothelial injury in N-nitro-L-arginine-induced hypertensive rats.
• Elucidate the molecular mechanisms of Edu's antihypertensive action using integrated proteomic and metabolomic analyses.
• Assess Edu's efficacy compared to sodium nitroprusside.

Main Methods:

• Induction of hypertension in rats using N-nitro-L-arginine.
• Physiological, biochemical, and histopathological assessments.
• Integrated proteomic and metabolomic analyses of thoracic aorta and serum.
• Comparative efficacy study with sodium nitroprusside.

Main Results:

• Edu demonstrated superior antihypertensive efficacy and ameliorated left ventricular dysfunction.
• Proteomic analysis revealed Edu's impact on pathways like the tricarboxylic acid cycle, fatty acid degradation, and oxidative phosphorylation.
• Metabolomics indicated Edu regulates bile acid, fatty acid, and lipid metabolism.
• Integrated analysis showed Edu reduced OXSM and MECR upregulation, suggesting regulation of fatty acid metabolism balance.

Conclusions:

• Edulinine (Edu) exerts protective and antihypertensive effects in L-NNA-induced hypertensive rats.
• Potential mechanisms include inhibiting OXSM and MECR, balancing fatty acid metabolism, and improving lipid metabolism disorders.
• Edu shows significant therapeutic potential for hypertension management.
