Plasma Biomarker Screening Based on Proteomic Signature of Patients with Resistant Hypertension.

Abstract

Resistant hypertension (RH) poses a significant health challenge, yet its underlying pathogenesis remains unclear. This study employs untargeted proteomic techniques to analyze the plasma of patients with RH and controlled hypertension (CH), identifying 157 differentially expressed proteins, with TGFB1 emerging as a key candidate. Through gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment, Protein-Protein Interaction Networks (PPI) topological analysis, TGFB1's differential regulation in RH is established. ELISA verification solidifies TGFB1's role, marking it as a potential biological target for early RH diagnosis and treatment. The study underscores the importance of proteomic approaches in enhancing our understanding of RH and improving therapeutic strategies. These findings carry implications for advancing RH diagnostics and treatment modalities, addressing a critical gap in current knowledge.
