Abstract
The runt-related transcription factor 3 (RUNX3) regulates the differentiation of monocytes and their response to inflammation. However, the transcriptomic context of RUNX3 expression in blood monocytes remains poorly understood. We aim to learn about RUNX3 from its relationships within transcriptomes of bulk CD14+ cells in adults. This study used immunomagnetically sorted CD14+ cell gene expression microarray data from the Multi-Ethnic Study of Atherosclerosis (MESA, n = 1202, GSE56047) and the Correlated Expression and Disease Association Research (CEDAR, n = 281, E-MTAB-6667) cohorts. The data were preprocessed, subjected to RUNX3-focused correlation analyses and random forest modeling, followed by the gene ontology analysis. Immunity-focused differential ratio analysis with intermediary inference (DRAIMI) was used to integrate the data with protein-protein interaction network. Correlation analysis of RUNX3 expression revealed the strongest positive association for EVL (rmean = 0.75, pFDR-MESA = 5.37 × 10-140, pFDR-CEDAR = 5.52 × 10-80), ARHGAP17 (rmean = 0.74, pFDR-MESA = 1.13 × 10-169, pFDR-CEDAR = 9.20 × 10-59), DNMT1 (rmean = 0.74, pFDR-MESA = 1.10 × 10-169, pFDR-CEDAR = 1.67 × 10-58), and CLEC16A (rmean = 0.72, pFDR-MESA = 3.51 × 10-154, pFDR-CEDAR = 2.27 × 10-55), while the top negative correlates were C2ORF76 (rmean = -0.57, pFDR-MESA = 8.70 × 10-94, pFDR-CEDAR = 1.31 × 10-25) and TBC1D7 (rmean = -0.55, pFDR-MESA = 1.36 × 10-69, pFDR-CEDAR = 7.81 × 10-30). The RUNX3-associated transcriptome signature was involved in mRNA metabolism, signal transduction, and the organization of cytoskeleton, chromosomes, and chromatin, which may all accompany mitosis. Transcriptomic context of RUNX3 expression in monocytes hints at its relationship with cell growth, shape maintenance, and aspects of the immune response, including tyrosine kinases.

Abstract
BACKGROUND Although important progress has been made in understanding Lp(a) (lipoprotein[a])-mediated stroke risk, the contribution of Lp(a) to the progression of vulnerable plaque features associated with stroke risk remains unclear. This study aims to evaluate whether Lp(a) is associated with carotid plaque progression, new-onset plaque features, and plaque vulnerability in a prospective community-based cohort study. METHODS Baseline Lp(a) levels were measured using latex-enhanced turbidimetric immunoassay among 804 participants aged 45 to 74 years and free of cardiovascular disease in the Chinese Multi-provincial Cohort Study-Beijing project. Carotid atherosclerosis was measured twice by B-mode ultrasonography over a 10-year interval during the 2002 and 2012 surveys to assess the progression of total, vulnerable and stable plaques, and plaque vulnerability. The total plaque area and plaque vulnerability score were calculated. RESULTS The median baseline Lp(a) level was 10.20 mg/dL (interquartile range, 6.20 to 17.18 mg/dL). Modified Poisson regression analysis showed that Lp(a) ≥50 mg/dL was significantly associated with 10-year progression of total carotid plaque (relative risk [RR], 1.41 [95% CI, 1.21-1.64]; E-value=2.17), vulnerable plaque (RR, 1.93 [95% CI, 1.54-2.41]), and stable plaque (RR, 1.51 [95% CI, 1.11-2.07]) compared with Lp(a) <50 mg/dL. Moreover, among participants without plaque at baseline, Lp(a) ≥50 mg/dL was related to an increased total plaque area (β=0.36 [95% CI, 0.06-0.65]; P=0.018) and increased plaque vulnerability score (β=0.30 [95% CI, 0.01-0.60]; P=0.045) in multivariable linear regression. CONCLUSIONS Elevated Lp(a) levels were associated with 10-year carotid plaque progression and plaque vulnerability, providing a basis for Lp(a) as a treatment target for stroke prevention.

Abstract
AIM Coronary artery disease (CAD) is a major health problem in developed and developing nations. Development of CAD involves a complex interaction between genetics and lifestyle factors. Individuals with high-risk genetic predisposition along with poor lifestyle are more inclined to the development of CAD. Advancement in genotyping technologies and increase in genome wide studies has provided a platform to identify new risk factors associated with CAD and associated complexities. METHODOLOGY In this study we performed genome wide screening in 76 well-defined CAD cases and 77 control samples in Indian population. Interestingly, new variants are identified in three genes viz, VLDLR, IFITM2 and C2CD4C. RESULTS The odds ratios observed for variant rs1869592 (VLDLR), rs1059091 (IFITMI) and rs7247159 (C2CD4C) were 2.6 (1.4-4.8 95% CI), 1.9 (95% CI 1.2-3.1) and 2.1 (1.2-3.7 95% CI), respectively with significant P value <0.01. These variants that are associated with pathogenesis of CAD were not previously reported in literature. Moreover, we anticipate that these variants will be further validated using a larger sample size.

Oncostatin M reduces atherosclerosis development in APOE*3Leiden.CETP mice and is associated with increased survival probability in humans. PLoS One 2019; 14:e0221477.

Abstract
Objective Previous studies indicate a role for Oncostatin M (OSM) in atherosclerosis and other chronic inflammatory diseases for which inhibitory antibodies are in development. However, to date no intervention studies with OSM have been performed, and its relation to coronary heart disease (CHD) has not been studied. Approach and results Gene expression analysis on human normal arteries (n = 10) and late stage/advanced carotid atherosclerotic arteries (n = 127) and in situ hybridization on early human plaques (n = 9) showed that OSM, and its receptors, OSM receptor (OSMR) and Leukemia Inhibitory Factor Receptor (LIFR) are expressed in normal arteries and atherosclerotic plaques. Chronic OSM administration in APOE*3Leiden.CETP mice (n = 15/group) increased plasma E-selectin levels and monocyte adhesion to the activated endothelium independently of cholesterol but reduced the amount of inflammatory Ly-6CHigh monocytes and atherosclerotic lesion size and severity. Using aptamer-based proteomics profiling assays high circulating OSM levels were shown to correlate with post incident CHD survival probability in the AGES‐Reykjavik study (n = 5457). Conclusions Chronic OSM administration in APOE*3Leiden.CETP mice reduced atherosclerosis development. In line, higher serum OSM levels were correlated with improved post incident CHD survival probability in patients, suggesting a protective cardiovascular effect.

Abstract
It is well‐established that homocysteine (Hcy) is an independent risk factor for atherosclerosis. Hcy can promote vascular smooth muscle cell (VSMC) proliferation, it plays a key role in neointimal formation and thus contribute to arteriosclerosis. However, the molecular mechanism on VSMCs proliferation underlying atherosclerosis is not well elucidated. Mitofusin‐2 (MFN2) is an important transmembrane GTPase in the mitochondrial outer membrane and it can block cells in the G0/G1 stage of the cell cycle. To investigate the contribution of aberrant MFN2 transcription in Hcy‐induced VSMCs proliferation and the underlying mechanisms. Cell cycle analysis revealed a decreased proportion of VSMCs in G0/G1 and an increased proportion in S phase in atherosclerotic plaque of APOE−/− mice with hyperhomocystinaemia (HHcy) as well as in VSMCs exposed to Hcy in vitro. The DNA methylation level of MFN2 promoter was obviously increased in VSMCs treated with Hcy, leading to suppressed promoter activity and low expression of MFN2. In addition, we found that the expression of c‐Myc was increased in atherosclerotic plaque and VSMCs treated with Hcy. Further study showed that c‐Myc indirectly regulates MFN2 expression is duo to the binding of c‐Myc to DNMT1 promoter up‐regulates DNMT1 expression leading to DNA hypermethylation of MFN2 promoter, thereby inhibits MFN2 expression in VSMCs treated with Hcy. In conclusion, our study demonstrated that Hcy‐induced hypermethylation of MFN2 promoter inhibits the transcription of MFN2, leading to VSMCs proliferation in plaque formation, and the increased binding of c‐Myc to DNMT1 promoter is a new and relevant molecular mechanism.

Abstract
Studies have investigated the association between angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and cardiometabolic risk factors (CMRFs), however with varying results, which could be due to ethnicity differences. Therefore, the present study was conducted among Bhil tribal population (a mendelian population with the common gene pool and same sociocultural attributes), residing in two different environmental settings. The study attempts to understand the distribution and extent of association of ACE I/D gene polymorphism with cardiometabolic risk factors among Bhils from rural and urban settings. All the obesity and blood pressure variables were collected form 432 recruited subjects from both sexes aged 25-65 years and ACE I/D polymorphism was analysed on 299 subjects. Almost all the studied CMRFs were found to be significantly higher among urban Bhils. ACE gene was found to be polymorphic in the studied groups. DD genotype was found to pose more than threefold significant risk for low HDLC only in rural area. Estimate change analysis revealed an increasing D allele dose leads to more than one unit increase in Blood Pressure, and more than three units decrease in HDLC. The study highlights the differential effect of ACE I/D gene polymorphism in different environmental settings.
