Area Of Science

  • Biochemistry
  • Vascular Biology
  • Metabolomics

Background

  • Carotid atherosclerosis is a progressive vascular disease.
  • Stroke is a severe complication of advanced carotid atherosclerosis.
  • Lack of reliable biomarkers hinders early diagnosis and treatment of high-risk individuals.

Purpose Of The Study

  • To identify metabolic markers in carotid plaques associated with stroke risk.
  • To explore potential targets for pharmacological interventions in carotid atherosclerosis.

Main Methods

  • Untargeted metabolomics using liquid chromatography-tandem mass spectrometry on carotid intima and plaque tissues from 20 patients.
  • Multivariate and univariate statistical analyses were employed.

Main Results

  • 154 metabolites were significantly altered in carotid plaques compared to thickened intima.
  • Key biomarkers including N-(cyclopropylmethyl)-N'-phenylurea, 9(S)-HOTrE, and l-thyroxine were identified.
  • Disrupted purine, nucleotide, amino acid, glutathione, and vitamin metabolism pathways were implicated in plaque progression.

Conclusions

  • Identified novel biomarkers for stroke-prone carotid plaques.
  • Elucidated metabolic mechanisms underlying carotid atherosclerosis progression.
  • Provides a basis for precise prevention and targeted therapies for carotid atherosclerosis.
