Project description:Aberrantly expressed miRNAs contribute to developmental abnormalities and diseases such as cancer, diabetes, and cardiovascular disorders, by hybridizing to specific mRNA targets and repressing their translation into proteins. Although miRNA expression signature is characterized in the process of neointimal thickening during proliferative vascular diseases such as atherosclerosis, so far global miRNA expression profiling in the different stages of atherosclerosis is completely unknown. We explored stage-specific microRNA signatures in the progress of atherosclerosis in hyperlipidemia mouse model, which may help to identify the critical miRNAs contributing atherosclerotic development and stabilization.

Project description:The rupture of atherosclerotic plaque contributes significantly to cardiovascular disease (CVD). Plasma concentrations of bilirubin, a by-product of heme catabolism, inversely associate with risk of CVD, although the link between bilirubin and atherosclerosis remains unclear.

Female apoe-/- mice (6-8 weeks, Jackson Laboratory) were fed a high fat diet (HFD, 21% crude fat, 0.15% cholesterol and 19.5% casein, Altromin, Germany) for 3 or 10 months (N=3-4). Serial sections (20 µm thick) of aortic roots and carotid arteries from these mice were mounted on membrane mounted metal frame slides (MMI), deparaffinized under RNase-free conditions, and completely dried. Laser capture microdissection (LCM) was performed with a laser microdissection system (MMI cellcut plus, Molecular Machines and Industries, Switzerland) assembled onto an inverted microscope (Olympus IX71). Plaque tissue or morphologically normal vessel wall of at least 40 sections per mouse were collected. RNA was isolated using RecoverAll total nucleic acid isolation kit (Applied Biosystems) according to the manufacturer’s instructions.

Project description:Atherosclerosis is characterized by thickening of the arterial wall and is the primary cause of the coronary artery disease and cerebrovascular disease, two of the most common causes of illness and death worldwide. One of the leading risk factors for development of atherosclerosis is familial hypercholesterolemia. Familial hypercholesterolemia is an autosomal dominant disorder, which is caused by mutations mainly located in the low-density lipoprotein receptor (LDLR) gene. It is characterized by elevated levels of low-density lipoprotein cholesterol, the presence of tendon xanthomas, and premature cardiovascular disease. Aim of this study was to find atherosclerotic markers in white blood cells of patients compared to healthy controls. None of these patients exhibited symptoms of atherosclerosis by standard diagnostic methods; however, transcriptome analysis of blood RNA indicated changes in ubiquitin proteolysis and cell adhesion system as expected in initiation steps of atherosclerosis.

Project description:The rupture of unstable atherosclerotic plaques, leading to debilitating or fatal thrombotic events, is a major health burden worldwide. Limited understanding as to the molecular drivers of plaque instability and rupture hinders efforts in diagnosis and treatment prior to thrombotic events. Utilising an advanced pre-clinical mouse model (Tandem stenosis (TS) model), which presents human-like unstable atherosclerotic disease, we apply high-end omic methods to characterize the molecular signatures associated with plaque instability in atherosclerotic arteries. Through quantitative proteomic profiling, we depict unique proteome signatures of unstable plaques compared to stable plaques and healthy arteries. Coupled with single-cell RNA-sequencing of leukocytes, we describe the heterodimer complex S100a8/S100a9 as unique to unstable plaque, with neutrophils implicated as the transcriptional drivers of S100a8/a9 expression. We confirm S100a9 expression in human carotid atherosclerotic plaques and we further utilise the TS pre-clinical model to pharmacologically inhibit S100a8/S100a9, resulting in plaque stabilisation. Thus, we establish the TS model as a sophisticated translational tool for the profiling of unstable atherosclerotic plaques and demonstrate that unstable and stable atherosclerosis are highly different disease entities.

Experiment Overall Design: Five patients diagnosed with Familial hypercholesterolemia and five age, sex, BMI and smoking status matched controls contributed blood from which total RNA from white blood cells was isolated. RNA samples were analyzed using Affymetrix microarrays and two groups were compared for differentially expressed genes.
