Proteomic analysis associated with coronary artery dilatation caused by Kawasaki disease using serum exosomes
Insights
Researchers identified 38 differentially expressed proteins in serum exosomes of children with coronary artery dilatation (CAD) from Kawasaki disease (KD). These proteins offer new insights into the mechanisms of KD-induced CAD.
Area of Science:
- Biochemistry
- Immunology
- Proteomics
Background:
- Kawasaki disease (KD) can lead to coronary artery dilatation (CAD).
- The proteomic profile of serum exosomes in KD-induced CAD is not well understood.
Purpose of the Study:
- To investigate the serum exosome proteome profile in children with KD-induced CAD.
- To identify differentially expressed proteins associated with KD-induced CAD.
Main Methods:
- Serum exosomes were isolated from children with KD-induced CAD and healthy controls.
- Proteomic analysis was performed using two-dimensional electrophoresis and mass spectrometry.
- Differentially expressed proteins were validated by western blot analysis.
Main Results:
- 38 differentially expressed proteins were identified in serum exosomes from patients with KD-induced CAD compared to controls.
- 13 proteins were up-regulated, and 25 were down-regulated.
- Key proteins identified are involved in inflammatory and coagulation pathways, including leucine-rich alpha-2-glycoprotein, sex hormone-binding globulin, and serotransferrin.
Conclusions:
- This study provides a comprehensive proteome profile of serum exosomes in KD-induced CAD.
- The findings enhance understanding of the underlying mechanisms of KD-induced CAD.
Introduction:
The aim of this study was to investigate the serum exosome proteome profile of coronary artery dilatation (CAD) caused by Kawasaki disease (KD).
Methods:
Two-dimensional electrophoresis was implemented on proteins of serum exosomes obtained from children with CAD caused by KD and from healthy controls. Differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry analysis.
Results:
We identified 38 differentially expressed proteins (13 up-regulated and 25 down-regulated) from serum exosomes of patients with CAD caused by KD compared with healthy controls. Expression levels of three differentially expressed proteins (leucine-rich alpha-2-glycoprotein, sex hormone-binding globulin, and serotransferrin) were validated using western blot analysis. Classification and protein-protein network analysis showed that they are associated with multiple functional groups involved in the acute inflammatory response, defense response, complement activation, humoral immune response, and response to wounding. The majority of the proteins are involved in the inflammation and coagulation cascades.
Conclusions:
These findings establish a comprehensive proteome profile of CAD caused by KD and increase our knowledge of scientific insight into its mechanisms.
