Comparative Analysis of Transcriptome Profiles in Patients with Thromboangiitis Obliterans

Area of Science:

• Vascular Biology
• Molecular Medicine
• Genomics

Background:

• Thromboangiitis Obliterans (TAO) is a vascular disease causing limb ischemia due to inflammation and thrombosis in small and medium arteries.
• Diagnosis often relies on clinical criteria, highlighting the need for objective biomarkers.

Purpose of the Study:

• To identify potential diagnostic biomarkers for Thromboangiitis Obliterans (TAO) by analyzing gene expression profiles.
• To understand the molecular mechanisms underlying TAO.

Main Methods:

• Microarray analysis of whole blood RNA from 15 male TAO patients and 5 healthy controls.
• Comparative analysis to identify differentially expressed genes (DEGs).
• Protein-protein interaction and pathway analysis to identify key genes and biological pathways.

Main Results:

• 477 common genes were identified, with 79 upregulated and 398 downregulated in TAO patients.
• 11 key genes, including FMNL1, RNF149, and RPL27A, were identified based on differential expression.
• Pathway analysis revealed involvement of immune system, stress response, and cytokine signaling.

Conclusions:

• The identified genes and pathways offer insights into the molecular basis of TAO.
• Further investigation into protein expression of these genes could lead to novel diagnostic and predictive biomarkers for TAO.
