Abstract
Activin receptor-like kinase 1 (ALK1) is a transmembrane serine/threonine receptor kinase of the transforming growth factor beta (TGFβ) receptor superfamily. ALK1 is specifically expressed in vascular endothelial cells, and its dynamic changes are closely related to the proliferation of endothelial cells, the recruitment of pericytes to blood vessels, and functional differentiation during embryonic vascular development. The pathophysiology of many cerebrovascular diseases is today understood as a disorder of endothelial cell function and an imbalance in the proportion of vascular cells. Indeed, mutations in ALK1 and its co-receptor endoglin are major genetic risk factors for vascular arteriovenous malformation. Many studies have shown that ALK1 is closely related to the development of cerebral aneurysms, arteriovenous malformations, and cerebral atherosclerosis. In this review, we describe the various roles of ALK1 in the regulation of angiogenesis and in the maintenance of cerebral vascular homeostasis, and we discuss its relationship to functional dysregulation in cerebrovascular diseases. This review should provide new perspectives for basic research on cerebrovascular diseases and offer more effective targets and strategies for clinical diagnosis, treatment, and prevention.

Detection of Pathological Changes in the Aorta during Thoracic Aortic Aneurysm Progression on Molecular Level. DISEASE MARKERS 2017; 2017:9185934. [PMID: 29158612 PMCID: PMC5660829 DOI: 10.1155/2017/9185934] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/24/2017] [Revised: 07/12/2017] [Accepted: 08/24/2017] [Indexed: 12/22/2022]
Abstract
The progression of thoracic aortic aneurysm depends on regulation of aortic wall homeostasis and on changes in the structural components of the extracellular matrix, which are affected by multiple molecular signalling pathways. We decided to correlate the diameter of ascending thoracic aneurysm with gene expression of inflammation markers (IL-6, CRP), cytokine receptors (IL-6R, TNFR1, and TNFR2), and extracellular matrix components (Emilin-1, MMP9, and TIMP) for detection of the degree of pathological process of TAA formation. The experimental group was divided into three groups according to the diameter of the aortic aneurysm. Whole blood and tissue samples were properly collected and used for nucleic acid, chromatin, and protein isolation. The mRNA levels were detected by qRT-PCR. For the detection of protein levels a Cytokine Array IV assay kit was used in combination with a biochip analyzer. In aortic tissue, significant positive correlations were found between increased mRNA levels of inflammatory cytokines (CRP and IL-6) on both mRNA levels in tissue and protein from the blood with maximum in stage 3. Changes of gene expression of selected genes can be used for the experimental study of the inflammatory receptor inhibitors during trials targeted on slowing down the progress of aortic wall aneurysm.

Abstract
BACKGROUND Animal researches reported that the dysfunction of profilin1 (PFN1) was involved in the physiological arterial stiffness and vascular remodeling linking to the etiology of hypertension (HT). This study mainly aims at evaluating the association of PFN1 and HT in a Han Chinese population. METHODS A case-control study consisted of 2,012 HT cases and 2,210 controls was conducted and 2,116 participants from the healthy controls were further followed up for average 5.01 years. Logistic and Cox regression models were applied to evaluate the association of 4 tag single nucleotide polymorphisms (SNPs) of PFN1 and ENO3 with HT. RESULTS There was no significant association of the 4 SNPs between HT cases and controls even after adjustment for confounding factors (P > 0.05). Haplotype analysis did not identify any significant haplotype with HT. There were no statistical difference of systolic blood pressure (BP) and diastolic BP among different genotypes in antihypertensive-treated group and untreated group. In follow-up population, there was no significant association of candidate SNPs with HT even after adjustment for covariates (all P > 0.05). Of note, the plasma profilin1 level of HT cases was significantly higher than that of control subjects (P = 0.011). The profilin1 levels of controls significantly decreased with variation of rs238243 at PFN1 (P = 0.041), and the profilin1 levels of HT cases increased with variation of rs238238 at ENO3 (P = 0.004). CONCLUSIONS Our results suggest that HT cases displayed an elevated plasma profilin1. Variants of rs238243 and rs238238 might regulate profilin1 expression by epigenetic modification and indirectly affects the susceptible threshold of HT.

Monocyte adhesion to atherosclerotic matrix proteins is enhanced by Asn-Gly-Arg deamidation. Sci Rep 2017; 7:5765.

Abstract
Atherosclerosis arises from leukocyte infiltration and thickening of the artery walls and constitutes a major component of vascular disease pathology, but the molecular events underpinning this process are not fully understood. Proteins containing an Asn-Gly-Arg (NGR) motif readily undergo deamidation of asparagine to generate isoDGR structures that bind to integrin αvβ3 on circulating leukocytes. Here we report the identification of isoDGR motifs in human atherosclerotic plaque components including extracellular matrix (ECM) proteins fibronectin and tenascin C, which have been strongly implicated in human atherosclerosis. We further demonstrate that deamidation of NGR motifs in fibronectin and tenascin C leads to increased adhesion of the monocytic cell line U937 and enhanced binding of primary human monocytes, except in the presence of a αvβ3-blocking antibody or the αv-selective inhibitor cilengitide. In contrast, under the same deamidating conditions monocyte-macrophages displayed only weak binding to the alternative ECM component vitronectin which lacks NGR motifs. Together, these findings confirm a critical role for isoDGR motifs in mediating leukocyte adhesion to the ECM via integrin αvβ3 and suggest that protein deamidation may promote the pathological progression of human atherosclerosis by enhancing monocyte recruitment to developing plaques.

Abstract
Elastin microfibril interface-located protein 1 (EMILIN1), a glycoprotein, is associated with elastin in the extracellular matrix (ECM) of arteries, lymph vasculature, and other tissues. EMILIN1 particularly has a niche role in elastin fiber biogenesis (elastogenesis) by aiding with the fusion of elastin fibers, rendering them more ordered. In addition to elastogenesis, EMILIN1 has been shown to have roles in maintenance of vascular cell morphology, smooth muscle cell adhesion to elastic fibers, and transforming growth factor (TGFβ) regulation, by inhibiting TGFβ activation via blocking the proteolytic production of the latency-associated peptide/active TGFβ complex. The increased TGFβ signaling induced during EMILIN1 deficiency alters TGFβ activity, resulting in vascular smooth muscle cell growth and vascular remodeling. The increasing systemic blood pressure associated with TGFβ signaling may be closely linked to the activity of other mediators that affect cardiovascular homeostasis, such as angiotensin II. The increase in prevalence of hypertension and other cardiovascular diseases in other disease states likely involve a complex activation of TGFβ signaling and ECM dysfunction. Thus, the interaction of TGFβ and ECM components appears to be integrative involving both structural alterations to vessels through EMILIN1 and changes in TGFβ signaling processes. This review summarizes the current knowledge on the EMILIN1-TGFβ relationship; the specific roles of EMILIN1 and TGFβ in blood pressure regulation, their synergistic interaction, and in particular the role of TGFβ (in conjunction with ECM proteins) in other disease states altering cardiovascular homeostasis.

Abstract
BACKGROUND This study describes the effect of rapid tumor growth of patients suffering from various grades of malignant ductal breast carcinoma associated with the gene expression of ECM protein emilin 1, in correlation with the number of gene copies of emilin 1 and degradation of tumor tissue proteins. METHODS A total of 40 examined patients participated in the experiment (controls, n = 10, grades GI-GIII, each n = 10). After isolation of total mRNA, transcription of mRNA into the cDNA was performed. Quantification of gene expression changes was detected by the real-time PCR method. Analysis at the protein level was performed via Western blot method. RESULTS During the detection of changes at the mRNA level, a significantly decreased level of emilin 1 in tumor tissues with grade II (about 54 ± 8 % lower than control) was identified. Protein-level analysis indicated an increased level of emilin 1 in tumors with grade I in comparison with control samples (about 10 ± 3 %). CONCLUSION Obtained results demonstrated that the suppressive role of emilin 1 is related to the grade of growing breast tumors, and associated with increased hypoxia in the tumor microenvironment followed by elevated unfolding and degradation of tissue proteins.

Abstract
Aortic valve disease (AVD) is characterized by elastic fiber fragmentation (EFF), fibrosis and aberrant angiogenesis. Emilin1 is an elastin-binding glycoprotein that regulates elastogenesis and inhibits TGF-β signaling, but the role of Emilin1 in valve tissue is unknown. We tested the hypothesis that Emilin1 deficiency results in AVD, mediated by non-canonical (MAPK/phosphorylated Erk1 and Erk2) TGF-β dysregulation. Using histology, immunohistochemistry, electron microscopy, quantitative gene expression analysis, immunoblotting and echocardiography, we examined the effects of Emilin1 deficiency (Emilin1−/−) in mouse aortic valve tissue. Emilin1 deficiency results in early postnatal cell-matrix defects in aortic valve tissue, including EFF, that progress to latent AVD and premature death. The Emilin1−/− aortic valve displays early aberrant provisional angiogenesis and late neovascularization. In addition, Emilin1−/− aortic valves are characterized by early valve interstitial cell activation and proliferation and late myofibroblast-like cell activation and fibrosis. Interestingly, canonical TGF-β signaling (phosphorylated Smad2 and Smad3) is upregulated constitutively from birth to senescence, whereas non-canonical TGF-β signaling (phosphorylated Erk1 and Erk2) progressively increases over time. Emilin1 deficiency recapitulates human fibrotic AVD, and advanced disease is mediated by non-canonical (MAPK/phosphorylated Erk1 and Erk2) TGF-β activation. The early manifestation of EFF and aberrant angiogenesis suggests that these processes are crucial intermediate factors involved in disease progression and therefore might provide new therapeutic targets for human AVD.

Abstract
BACKGROUND An animal study reported that TGF-β1 maturation was linked to the homeostasis of blood pressure and elastogenesis of essential hypertension (EH). Recent advances require further research of TGF-β1 receptor in EH. METHODS A case-control study comprised of 2,012 adult hypertension case patients and 2,210 adult control subjects was conducted, and the association with blood pressure was further tested in children. Logistic regression and calculated genetic risk score were used to evaluate the effects of one single nucleotide polymorphism (SNP) and multiple SNPs on EH, respectively. RESULTS The genetic risk score of 10 SNPs showed a significant association with hypertension; the odds ratio of the upper quartile vs. the lower quartile was 1.282 (P = 4.67 × 10(-3)). rs7256241 in miR-518 was significantly associated with diastolic blood pressure (DBP) change in control subjects (P = 0.002), and this association was also observed in children (P = 0.04). The systolic blood pressure (SBP) and DBP of female patients taking reserpine were higher with the C and G alleles of rs3773661 (P = 0.004) and rs7256241 (P = 0.002), respectively. In patients taking Zhen Ju Jiang Ya tablets, SBP and DBP decreased linearly with rs749794 (P = 0.004 and P = 0.048, respectively). SBP decreased linearly with rs1155705 (P = 0.007) and rs11709624 (P = 0.04), but increased with rs1036096 (P = 0.03) in male patients. In male patients taking Jiang Ya tablets, SBP increased linearly with rs11709624 (P = 0.007), DBP increased linearly with rs1155705 (P = 0.03) whereas decreased with rs7256241 (P = 0.04). CONCLUSIONS Our results suggest that TGFBR2 and miR-518 harbor variants that increase the risk of EH and affect blood pressure homeostasis as well as efficacy of antihypertensive agents.

Abstract
BACKGROUND High-mobility group box 1 protein (HMGB1) acts as a proinflammatory cytokine by activating pattern recognition receptors (PRRs), including Toll-like receptor 4 (TLR4) and the receptor of AGE (AGER) with oxidative injury. Animal study proved that HMGB1 contributed to the pathogenesis of experimental pulmonary hypertension (HT) via activation of TLR4. The aim of this study is to test whether HMGB1 harbor genetic susceptibility to HT in a Chinese population. METHODS A case-control study comprising 2012 HT cases and 2210 controls was used to evaluate the association of three tagging single nucleotide polymorphism (tagSNPs) in HMGB1 gene with HT and blood pressure. Logistic regression model was used to adjust confounding factor for HT and general linear model (GLM) was applied to compare blood pressure levels between genotypes in cases and controls. RESULTS Single locus analysis showed that there was no statistical association of three tagSNPs with HT after adjustment for the covariates. Further stratification analysis found that rs2249825 was significantly associated with HT in ≥55 years groups, ORs (95% CI) of additive model and dominant model were 1.208 (1.029-1.417) and 1.212 (1.020-1.441), and p values were 0.021 and 0.029, respectively. Quantitative trait analysis indicated that DBP had a linear decrease with the variations of rs2249825 in both untreated HT group (p=0.002) and control group (p=0.034) respectively. CONCLUSIONS Our finding suggests that rs2249825 of HMGB1 genetic polymorphisms are significantly associated with HT and diastolic blood pressure, and the genetic effect on HT is modulated by age.

Abstract
BACKGROUND The GRK4 and EMILIN1 genes have been suggested to be involved in the development of hypertension. However, the results have been inconsistent. In this study, a meta-analysis was performed to clarify the associations of polymorphisms in the GRK4 and EMILIN1 genes with hypertension risk. METHODS Published literature from PubMed and Embase databases were retrieved. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using fixed- or random-effects model. RESULTS Five studies for polymorphisms in the GRK4 gene and five studies for polymorphisms in the EMILIN1 gene were identified. The results suggested that rs1801058 polymorphism in the GRK4 gene was inversely associated with hypertension among East Asians (TT vs. CC: OR=0.39, 95%CI 0.28-0.55) and positively associated with hypertension among Europeans (TT vs. CC: OR= 2.38, 95%CI 1.38-4.10). Rs2960306 polymorphism in the GRK4 gene was significantly associated with hypertension among Europeans (TT vs. GG: OR=1.92, 95%CI 1.13-3.27). The significant associations were also observed for rs2011616 and rs2304682 polymorphisms in the EMILIN1 gene among Japanese (rs2011616: AA vs. GG: OR=0.38, 95%CI 0.18-0.82; rs2304682: GG vs. CC: OR=0.37, 95%CI 0.17-0.81) but not among Chinese. CONCLUSIONS This meta-analysis suggested that rs1801058 polymorphism in the GRK4 gene was associated with hypertension in East Asians and Europeans. The significant association was also found for rs2960306 polymorphism in the GRK4 gene among Europeans. In addition, there were significant associations of rs2011616 and rs2304682 polymorphisms in the EMILIN1 gene with hypertension among Japanese.

Abstract
Studies in mice suggest that the elastin microfibril interfacer-1 gene (EMILIN1), the gene encoding elastin microfibril interfacer-1 protein, contributes to the pathogenesis of essential hypertension (EH) in humans. EMILIN1 in part maintains elastic fibres in vessel walls, and hence peripheral arterial compliance. In a case-control study, we assessed 942 non-obese non-diabetic Chinese, comprising 467 patients with EH and 475 normotensive control subjects (166 without, and 309 with, family history of hypertension in first-degree relatives (FHH)). Hypertension in first-degree relatives occurred in 88%, 65% and 0% of cases, all controls and controls without FHH, respectively. We scanned for single-nucleotide polymorphisms (SNPs) and genotyped them in the EMILIN1 gene using high-resolution melt-curve analysis. No exonic variants were detected. We assessed the association of SNPs and their haplotypes with EH. Three SNPs in introns 1 and 5 (rs2289360, rs2011616 and rs7424556) were in strong pair-wise linkage disequilibrium (r(2)>0.89). All three SNPs were significantly associated with hypertension. Genotypic frequencies at the three SNPs differed significantly between cases and only those controls without FHH. Healthy controls with FHH should be excluded to increase the odds of detecting association. All the G alleles of rs2289360 (odds ratio = 1.69, P = 0.010), rs2011616 (odds ratio = 1.52, P = 0.038) and rs7424556 (odds ratio = 1.59, P = 0.023) were high-risk alleles in the recessive genetic model. We observed significant overall haplotypic association with EH (empirical P = 0.0072); GGG is a risk haplotype (P = 0.043). The overall results support EMILIN1 as a candidate gene for human EH.

Abstract
BACKGROUND Elastin microfibril interfacer 1 (EMILIN-1) is a negative regulator of the transforming growth factor-beta (TGF-beta) signaling, which is involved in blood pressure (BP) homeostasis. Emilin1 knockout mice display elevated BP. The aim of the present study was to assess the association between the human EMILIN1 gene and essential hypertension (EH) using a haplotype-based case-control study. METHODS A total of 287 EH patients and 253 age-matched controls were genotyped for the five single-nucleotide polymorphisms (SNPs) used as genetic markers for the human EMILIN1 gene (rs2289408, rs2289360, rs2011616, rs2304682, and rs4665947). Data were analyzed for three separate groups: the total subjects, men, and women. RESULTS For the total, the genotypic distribution of rs2289360, rs2011616, and rs2304682 differed significantly between control and EH (P = 0.010, P = 0.009, and P = 0.008, respectively). For the total and men, there were significant differences noted between the controls and the EH patients for both the dominant model (GG vs. AA+AG) (P = 0.006, P = 0.021, respectively), and the recessive model (AA vs. AG+GG) (P = 0.028, P = 0.038, respectively) of rs2011616. For the total and the men, logistic regression analysis indicated that the AG+GG genotype of rs2011616 was significantly higher in EH patients (P = 0.033, P = 0.043, respectively). The frequency of the G-G-T haplotype (established by rs2536512, rs2016116, rs17881426) was significantly higher in EH men (P = 0.007), and the G-A-T haplotype (established by rs2536512, rs2016116, rs17881426) was significantly higher in control men (P < 0.001). CONCLUSIONS We confirmed that rs2289360, rs2011616, and rs2304682 in the human EMILIN1 gene, as well as the haplotype constructed using rs2536512, rs2011616, and rs17881426 are useful genetic markers of EH in Japanese men.
