Abstract
RNA editing, a common and potentially highly functional form of RNA modification, encompasses two different RNA modifications, namely adenosine to inosine (A-to-I) and cytidine to uridine (C-to-U) editing. As inosines are interpreted as guanosines by the cellular machinery, both A-to-I and C-to-U editing change the nucleotide sequence of the RNA. Editing events in coding sequences have the potential to change the amino acid sequence of proteins, whereas editing events in noncoding RNAs can, for example, affect microRNA target binding. With advancing RNA sequencing technology, more RNA editing events are being discovered, studied, and reported. However, RNA editing events are still often overlooked or discarded as sequence read quality defects. With this position paper, we aim to provide guidelines and recommendations for the detection, validation, and follow-up experiments to study RNA editing, taking examples from the fields of cardiovascular and brain disease. We discuss all steps, from sample collection, storage, and preparation, to different strategies for RNA sequencing and editing-sensitive data analysis strategies, to validation and follow-up experiments, as well as potential pitfalls and gaps in the available technologies. This paper may be used as an experimental guideline for RNA editing studies in any disease context.

Abstract
Soft skills are the elementary management, personal, and interpersonal abilities that are vital for an individual to be efficient at workplace or in their personal life. Each work place requires different set of soft skills. Thus, in addition to scientific/technical skills that are easier to access within a short time frame, several key soft skills are essential for the success of a researcher in today's international work environment. In this paper, the trainees and trainers of the EU-CardioRNA COST Action CA17129 training school on soft skills present basic and advanced soft skills for early career researchers. Here, we particularly emphasize on the importance of transferable and presentation skills, ethics, literature reading and reviewing, research protocol and grant writing, networking, and career opportunities for researchers. All these skills are vital but are often overlooked by some scholars. We also provide tips to ace in aforementioned skills that are crucial in a day-to-day life of early and late career researchers in academia and industry.

Abstract
Coronary artery disease (CAD) is a leading cause of mortality worldwide. In this study, we aimed to assess the potential of plasma long non-coding RNAs (lncRNAs) LIPCAR and MALAT1 and microRNAs (miRNAs) miR-142-3p and miR-155-5p to discriminate unstable CAD patients from stable ones. 23 stable angina (SA), 21 unstable angina (UA), and 50 ST-segment elevation myocardial infarction (STEMI) patients were enrolled; their plasma was collected. ncRNA plasma levels were evaluated using RT-qPCR. All measured ncRNA levels were significantly increased in UA patients' plasma compared to SA patients' plasma and in STEMI-with major adverse cardiovascular event (MACE) patients' plasma vs. STEMI-without MACE patients' plasma. ROC analysis showed that increased levels of LIPCAR and MALAT1 were associated with UA, and the prognostic model improved with the addition of miR-155-5p levels. The assessed lncRNAs discriminated between hyperglycemic (HG) and normoglycemic (NG) UA patients, and they were associated with MACE incidence in STEMI patients; this prediction was improved by the addition of miR-142-3p levels to the ROC multivariate model. We propose LIPCAR and MALAT1 as effective diagnostic markers for vulnerable CAD, their association with HG in UA patients, and as robust predictors for unfavorable evolution of STEMI patients.

Abstract
Myocardial infarction is one of the leading causes of death worldwide, despite numerous efforts to find efficient prognostic biomarkers and treatment targets. In the present study, we aimed to assess the potential of six microRNAs known to be involved in cardiovascular diseases, cell-free DNA (cfDNA), and mitochondrial DNA (mtDNA) circulating in plasma to be used as prognostic tools for the occurrence of unfavorable outcomes such as major adverse cardiovascular events (MACE) after acute ST-segment elevation myocardial infarction (STEMI). Fifty STEMI patients were enrolled and monitored for 6 months for the occurrence of MACE. Plasma was collected at three time points: upon admission to hospital (T0), at discharge from hospital (T1), and 6 months post-STEMI (T6). Plasma levels of miR-223-3p, miR-142-3p, miR-155-5p, miR-486-5p, miR-125a-5p, and miR-146a-5p, as well as of cfDNA and mtDNA, were measured by RT-qPCR. Results showed that the levels of all measured miRNAs, as well as of cfDNA and mtDNA, were the most increased at T1, compared to the other two time points. In the plasma of STEMI patients with MACE compared to those without MACE, we determined increased levels of miRNAs, cfDNA, and mtDNA at T1. Hence, we used the levels of all measured parameters at T1 for further statistical analysis. Statistical analysis demonstrated that all six miRNAs and cfDNA plus mtDNA levels, respectively, were associated with MACE. The minimal statistical model that could predict MACE in STEMI patients was the combination of mtDNA and miR-142-3p levels, as evidenced by ROC analysis (AUC = 0.97, p < 0.001). In conclusion, the increased plasma levels of mtDNA, along with miR-142-3p, could be used to predict unfavorable outcomes in STEMI patients.

Abstract
Peripheral artery disease (PAD) is an atherosclerotic disorder affecting arteries of the lower limbs, the major risk factors including dyslipidemia and diabetes mellitus (DM). We aimed to identify alterations of the proteins in high-density lipoproteins (HDL) associated with HDL dysfunction in PAD patients. HDL2 and HDL3 were isolated from plasma of PAD patients with/without DM (PAD-DM/PAD) and healthy subjects (N). Apolipoprotein AI (ApoAI), ApoAII, ApoCIII, clusterin (CLU), paraoxonase 1 (PON1), myeloperoxidase (MPO), and ceruloplasmin (CP) were measured in HDL2 /HDL3 and plasma. Oxidation and glycation of the analyzed proteins were assessed as malondialdehyde-protein adducts (MDA) and advanced glycation end-products (AGE), respectively. The anti-inflammatory effect of HDL3 was estimated as its potential to reduce monocyte adhesion to tumor necrosis factor α-activated endothelial cells. We show that in PAD patients compared to N subjects: (i) HDL2 presented increased levels of MDA-PON1, AGE-PON1, AGE-ApoAI, ApoAII, ApoCIII, and CP levels, and decreased PON1 levels; (ii) HDL3 had increased levels of MDA- and AGE-CLU and -ApoAI, MDA-PON1, ApoCIII, CLU, MPO, CP, and reduced PON1 levels. All these alterations were exacerbated by DM. These changes were more pronounced in HDL3 , which had reduced anti-inflammatory potential in PAD and became pro-inflammatory in PAD-DM. In PAD patients' plasma, CLU levels and MPO specific activity increased, while PON1 specific activity decreased. In conclusion, HDL function is altered in PAD patients due to multiple modifications of associated proteins that are aggravated by DM. Plasma CLU, MPO, and PON1 could constitute indicators of HDL dysfunction and contribute to risk stratification in PAD patients.

Abstract
There is an intensive effort to identify biomarkers to predict cardiovascular disease evolution. We aimed to determine the potential of microRNAs to predict the appearance of cardiovascular events (CVEs) in patients with peripheral artery disease (PAD) following femoral artery bypass surgery. Forty-seven PAD patients were enrolled and divided into two groups, without CVEs (n = 35) and with CVEs (n = 12), during 1 year follow-up. Intra-surgery atherosclerotic plaques from femoral arteries were collected and the levels of miR-142, miR-223, miR-155, and miR-92a of the primary transcripts of these microRNAs (pri-miRNAs), and gene expression of Drosha and Dicer were determined. Results showed that, in the plaques, miR-142, miR-223, and miR-155 expression levels were significantly increased in PAD patients with CVEs compared to those without CVEs. Positive correlations between these miRNAs and their pri-miRNAs levels and the Dicer/Drosha expression were observed. In the plasma of PAD patients with CVEs compared to those without CVEs, miR-223 and miR-142 were significantly increased. The multiple linear regression analyses revealed significant associations among several plasma lipids, oxidative and inflammatory parameters, and plasma miRNAs levels. Receiver operator characteristic (ROC) analysis disclosed that plasma miR-142 levels could be an independent predictor for CVEs in PAD patients. Functional bioinformatics analyses supported the role of these miRNAs in the regulation of biological processes associated with atherosclerosis. Taken together, these data suggest that plasma levels of miR-142, miR-223, miR-155, and miR-92a can significantly predict CVEs among PAD patients with good accuracy, and that plasma levels of miR-142 can be an independent biomarker to predict post-surgery CVEs development in PAD patients.

Abstract
Dyslipidemia is a documented risk factor for cardiovascular diseases and other metabolic disorders. Therefore, the analysis of hyperlipidemia (HL)-related miRNAs is a potential approach for achieving new prognostic markers in lipid-metabolism related diseases. We aimed to analyze specific distribution of miRNAs in different tissues from HL animals. Golden Syrian hamsters were fed either regular chow (NL) or high-fat diet (HL) for 12 weeks. Microarray miRNAs profiling was performed in liver, heart and small intestine and data analyzed by R-studio software. Functional enrichment bioinformatics analysis was performed using miRWalk and DAVID tools. We observed a dysregulation of miRNAs in HL tissues evidencing a discrete distribution in the heart-liver axis and three lipid metabolism-related miRNAs were identified: hsa-miR-223-3p, hsa-miR-21-5p, and hsa-miR-146a-5p. Expression levels of these miRNAs were increased in HL livers and hearts. Functional bioinformatics analysis showed involvement of these miRNAs in the regulation of biological processes altered in HL conditions such as lipid metabolic process, fat cell differentiation, regulation of smooth muscle cells and cardiac septum development. We identified a set of miRNAs dysregulated in different tissues of HFD-induced HL hamsters. These findings motivate further studies aiming to investigate novel molecular mechanisms of lipid metabolism and atherogenic HL.

Abstract
SCOPE To assess the impact of ginger extract (GIN) in stimulating the production of quality HDL and the cholesterol efflux in the small intestine (SI), key processes in the management of hyperlipidemia (HL)-induced hepatic steatosis, and atherosclerosis. METHODS AND RESULTS Three groups of hamsters are used: (i) N, fed standard diet, (ii) HL, fed high-fat diet for 21 weeks, and (iii) HL-GIN, HL treated with GIN for the last 5 weeks of diet. Apolipoprotein A-I (apoA-I), malondialdehyde-apoA-I (MDA-apoA-I), paraoxonase1 (PON1), and myeloperoxidase (MPO) are measured in plasma and SI. ATP-binding cassette A1 transporter (ABCA1), ABCG5/G8, liver X receptor α/β (LXRα/β), peroxisome proliferator-activated receptor γ (PPARγ), and sirtuin1 (SIRT1) are assessed in the SI. Results show that in HL plasma, GIN decreases MDA-apoA-I, MPO/PON1 ratio and increases HDL-cholesterol/total cholesterol. In HL-SI, GIN decreases MDA-apoA-I and MPO, increases ApoA-I, PON1, and ABCA1, and restores cholesterol efflux disturbed by HL (SIRT1-LXRα/β-PPARγ-ABCG8). GIN administration is associated with the reduction of the aortic valves lipid-deposits. CONCLUSION In HL conditions, GIN stimulates the functional HDL production by restoring apoA-I quality and quantity through inhibition of the oxidative stress, and increases cholesterol efflux in the SI. These effects are associated with the restoration of SIRT1-LXRα/β-PPARγ pathway.

Abstract
BACKGROUND Stearoyl CoA desaturases (SCD) are enzymes that convert saturated to monounsaturated fatty acids and have increased activity in hepatic steatosis. PURPOSE We aimed to investigate the potential of ginger extract (GIN) to modulate the liver SCD1 expression and activity in hyperlipidemic (HL) conditions, in order to lower lipid accumulation in the steatotic liver. STUDY DESIGN/METHODS Male Golden Syrian hamsters were divided in three groups: (i) fed with standard chow (N), (ii) fed with standard chow plus 3% cholesterol and 15% butter for 21 weeks (HL), (iii) HL treated with GIN (800 µg/kg body weight/day) in the last 5 weeks of fat diet (HL-GIN). Cholesterol (C), triglycerides (TG), non-esterified fatty acids (NEFA), SCD1 estimated activity (C16:1n7/C16:0; C18:1n9/C18:0) and gene expression, acetyl-CoA carboxylase (ACC), thiobarbituric acid reactive substances (TBARS), paraoxonase1 (PON1) and myeloperoxidase (MPO) were determined in the plasma and liver of all hamsters. We measured protein expression of endoplasmic reticulum stress (ERS) markers, gene and protein expression of liver X receptor α/β (LXRα/β), peroxisome proliferator-activated receptor γ (PPARγ), ATP-binding cassette sub-family G member 5/8 (ABCG5/G8) and 7α-hydroxylase1 (CYP7A1) in all hamsters' livers. RESULTS In plasma, in HL-GIN versus HL hamsters, SCD1 estimated activity was lower (27%; 15%, p < 0.05), NEFA levels decreased by 91%, p < 0.001, while C and TG levels did not vary; the oxidative stress expressed as MPO and TBARS levels decreased (15%; 11%, p < 0.01), while PON1 protein increased (75%, p < 0.05). In the liver of HL-GIN versus HL, C, TG, NEFA, MPO and TBARS levels decreased (8-40%, p < 0.05) and PON1 protein levels increased (30%, p < 0.05), SCD1 estimated activity decreased (8%; 9%, p < 0.05), in parallel with the reduced gene expression of SCD1 and ACC (70-80%, p < 0.05). The protein expression of the ERS sensors decreased (30-65%, p < 0.05), while that of ABCG5/G8, CYP7A1, LXRα/β and PPARγ increased in HL-GIN (20-30%, p < 0.05) versus HL liver. CONCLUSION GIN reduces SCD1 estimated activity and expression, as well as the lipids accumulated in the livers of HL hamsters. This is achieved through a mechanism involving the decrease of the oxidative and ERS, and the enhancement of cholesterol efflux.
