چکیده انگلیسی


- We studied 82 proteins in relation to plaque prevalence in carotid arteries.
- Seven proteins were significantly associated with carotid plaques.
- Of these, renin, GH, osteoprotegerin and TNFSF14 were independently associated.

Background and aimsWe used a proteomics array to simultaneously measure multiple proteins that have been suggested to be associated with atherosclerosis and related them to plaque prevalence in carotid arteries in a human population-based study.MethodsIn the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS; n = 931, 50% women, all aged 70 years), the number of carotid arteries with plaques was recorded by ultrasound. Levels of 82 proteins were assessed in plasma by a proximity extension assay (Proseek Multiplex CVD, Olink Bioscience, Uppsala, Sweden) and related to carotid measures in a regression framework.ResultsFollowing adjustment for multiple testing with Bonferroni correction, seven of the proteins were significantly related to the number of carotid arteries affected by plaques in sex-adjusted models (osteoprotegrin, T-cell immunoglobulin and mucin domain (TIM)-1, growth/differentiation factor 15 (GDF-15), matrix metalloprotease-12 (MMP-12), renin, tumor necrosis factor ligand superfamily member 14 (TNFSF14) and growth hormone). Of these, renin (odds ratio [OR], 1.30; 95% confidence interval [CI], 1.13-1.49 per standard deviation increase), growth hormone (OR, 1.24; 95% CI, 1.08-1.43), osteoprotegerin (OR, 1.22; 95% CI, 1.05-1.43) and TNFSF14 (OR, 1.17; 95% CI, 1.01-1.35) were related to plaque prevalence independently of each other and traditional cardiovascular risk factors.ConclusionA novel targeted proteomics approach using the proximity extension technique discovered several new associations of candidate proteins with carotid artery plaque prevalence in a large human sample.
