• Opis:
  Background: Dyslipidaemia is a major risk factor for atherosclerosis and cardiovascular diseases. The molecular mechanisms that translate dyslipidaemia into atherogenesis and reliable markers of its progression are yet to be fully elucidated. To address this issue, we conducted a comprehensive metabolomic and proteomic analysis in an experi‑ mental model of dyslipidaemia and in patients with familial hypercholesterolemia (FH). Methods: Liquid chromatography/mass spectrometry (LC/MS) and immunoassays were used to fnd out blood alterations at metabolite and protein levels in dyslipidaemic ApoE−/−/LDLR−/− mice and in FH patients to evaluate their human relevance. Results: We identifed 15 metabolites (inhibitors and substrates of nitric oxide synthase (NOS), low-molecular-weight antioxidants (glutamine, taurine), homocysteine, methionine, 1-methylnicotinamide, alanine and hydroxyproline) and 9 proteins (C-reactive protein, proprotein convertase subtilisin/kexin type 9, apolipoprotein C-III, soluble intercellular adhesion molecule-1, angiotensinogen, paraoxonase-1, fetuin-B, vitamin K-dependent protein S and biglycan) that diferentiated FH patients from healthy controls. Most of these changes were consistently found in dyslipidaemic mice and were further amplifed if mice were fed an atherogenic (Western or low-carbohydrate, high-protein) diet. Conclusions: The alterations highlighted the involvement of an immune-infammatory response system, oxidative stress, hyper-coagulation and impairment in the vascular function/regenerative capacity in response to dyslipidaemia that may also be directly engaged in development of atherosclerosis. Our study further identifed potential biomark‑ ers for an increased risk of atherosclerosis that may aid in clinical diagnosis or in the personalized treatment. Keywords: Dyslipidaemia, Atherosclerosis, Metabolome, Proteome, Pathological mechanisms, Serological biomarkers
