Summary
This study identifies key genes and pathways in acute type A aortic dissection (ATAAD), developing a diagnostic model to improve early detection and patient outcomes for this life-threatening condition.
Area of Science:
- Cardiovascular Research
- Molecular Biology
- Genomics
Background:
- Acute type A aortic dissection (ATAAD) is a critical cardiovascular emergency with high mortality.
- Current diagnostic methods and understanding of molecular mechanisms are limited, impacting patient outcomes.
- Emerging research points to immune dysregulation and cellular processes in ATAAD pathogenesis.
Purpose of the Study:
- To identify critical genes and molecular pathways involved in ATAAD.
- To develop a multi-omics diagnostic model for ATAAD.
- To evaluate potential therapeutic targets for ATAAD.
Main Methods:
- Analysis of transcriptome datasets using differential expression, WGCNA, and machine learning.
- Functional enrichment and immunoinfiltration analyses were performed.
- A nomogram diagnostic model was constructed and validated.
Main Results:
- Six core genes (Ccl2, Cdh8, Hk2, Tph1, Npy1r, Slc24a4) were identified, with four validated in clinical samples.
- Key pathways involved immune cell migration and extracellular matrix remodeling.
- A nomogram model showed high diagnostic accuracy (AUC=0.935).
Conclusions:
- Identified key molecular markers and pathways in ATAAD pathogenesis.
- The multi-omics diagnostic model shows promise for early ATAAD screening.
- Findings offer potential targets for future research and clinical applications.
