Resistant hypertension (RH) involves complex gene interactions. Key genes like GATA1 and EPB42, and pathways such as VEGF signaling, are crucial in RH development, offering new insights into its pathology.
Area of Science:
- Genomics
- Molecular Biology
- Cardiovascular Research
Background:
- Resistant hypertension (RH) is a high-risk hypertensive disorder with complex pathogenesis.
- Identifying key genes and pathways is crucial for understanding RH development.
Purpose of the Study:
- To identify hub differentially expressed genes (DEGs) and pathways associated with resistant hypertension.
- To elucidate the molecular mechanisms underlying RH.
Main Methods:
- Transcriptome sequencing of blood samples from RH patients and controls.
- Differential gene expression analysis (DESeq2) and weighted gene co-expression network analysis (WGCNA).
- Gene Ontology (GO) and KEGG pathway enrichment analyses, and protein-protein interaction (PPI) network construction.
Main Results:
- 731 DEGs and 2 RH-associated WGCNA modules were identified.
- 229 key DEGs were found, enriched in drug catabolic processes, hemoglobin complex, and peroxidase activity.
- Hub genes GATA1, EPB42, ANK1, SNCA were identified; GATA1 and EPB42 validated by qRT-PCR.
Conclusions:
- Resistant hypertension development involves synergistic gene action.
- Hub genes (GATA1, EPB42) and pathways (VEGF signaling, mitophagy) are significant in RH pathogenesis.
- Findings offer novel insights into RH pathological mechanisms.
