Abstract
Pericoronary adipose tissue (PCAT) is a source of microRNAs (miRs) that act as messengers for intercellular communication. We investigated whether the PCAT surrounding significant coronary atherosclerotic lesions shows specific miR expression patterns compared with PCAT surrounding plaque-free segments. We included 49 patients with 3-vessel coronary artery disease (CAD) and 19 patients with severe valvular disease but no CAD, who underwent elective cardiac surgery. The PCAT was harvested from two sites: adjacent to a significant atherosclerotic coronary lesion and from plaque-free segments. miR-133a, miR-21, miR-26b, miR-9, and miR-143 levels in PCAT cells were quantified by real-time reverse transcription polymerase chain reaction (data expressed as arbitrary units). Expression of miR-133, miR-21, and miR-26b in adipose tissue at a site without atherosclerotic lesion was much lower in patients with CAD than in those without CAD (0.82 ± 1.37 vs 1.86 ± 0.52, P < .001, 0.45 ± 1.3 vs 1.51 ± 1.11, P < .001, 0.3 ± 1.25 vs 1.2 ± 0.73, P = .02, respectively). In addition, miR-133, miR-21, and miR-143 in CAD patients showed significantly greater expression in PCAT from atherosclerotic lesion compared with plaque-free segments (1.32 ± 0.96 vs 0.82 ± 0.37 (P = .011), 0.91 ± 1.7 vs 0.3 ± 1.25 (P = .012), 1.2 ± 1.59 vs 0.43 ± 0.54 (P < .001), respectively). Our findings open new perspectives for the role of PCAT in the pathophysiology of atherosclerosis and should be further investigated.

Abstract
Atherosclerosis is a chronic inflammatory disease characterized by extensive remodeling of medium and large-sized arteries. Inward remodeling (=lumen shrinkage) of the vascular walls is the underlying cause for ischemia in target organs. Therefore, inward remodeling can be considered the predominant feature of atherosclerotic pathology. Outward remodeling (=lumen enlargement) is a physiological response compensating for lumen shrinkage caused by neointimal hyperplasia, but as a pathological response to changes in blood flow, outward remodeling leads to substantial arterial wall thinning. Thinned vascular walls are prone to rupture, and subsequent thrombus formation accounts for the majority of acute cardiovascular events. Pathological remodeling is driven by inflammatory cells which induce vascular smooth muscle cells to switch from quiescent to a proliferative and migratory phenotype. After decades of intensive research, the molecular mechanisms of arterial remodeling are starting to unfold. In this mini-review, we summarize the current knowledge of the epigenetic and transcriptional regulation of vascular smooth muscle cell phenotype switching from the contractile to the synthetic phenotype involved in arterial remodeling and discuss potential therapeutic options.

BIOMED RESEARCH INTERNATIONAL 2021; 2021:6682525. [PMID: 34337044 PMCID: PMC8292040 DOI: 10.1155/2021/6682525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 03/02/2021] [Accepted: 06/27/2021] [Indexed: 11/29/2022]
Abstract
The aim of the study is to examine the mechanism of Aralia armata (Wall.) Seem (AAS) in improving intimal hyperplasia after vascular injury in rats. Rats with femoral artery injury were randomly divided into three groups: the model group, AAS low-dose group (40 mg/kg), and AAS high-dose group (80 mg/kg). The sham operation group was used as a control group. HE staining was used to observe the changes in femoral artery vessels. Immunohistochemistry was adopted to detect α-SMA, PCNA, GSK-3β, and β-catenin proteins in femoral artery tissue. The CCK-8 test and wound healing assay were employed to analyze the effect of AAS on proliferation and migration of vascular smooth muscle cells (VSMCs) cultured in vitro. Western blotting (WB) and polymerase chain reaction (PCR) assays were used to evaluate the molecular mechanism. AAS reduced the stenosis of blood vessels and the protein expressions of α-SMA, PCNA, GSK-3β, and β-catenin compared to the model group. In addition, AAS (0-15 μg/mL) effectively inhibited the proliferation and migration of VSMCs. Moreover, the results of WB and PCR showed that AAS could inhibit the activation of β-catenin induced by 15% FBS and significantly decrease the expression levels of Wnt3α, Dvl-1, GSK-3β, β-catenin, and cyclin D1 in the upstream and downstream of the pathway. AAS could effectively inhibit the proliferation and migration of neointima after vascular injury in rats by regulating the Wnt/β-catenin signaling pathway.

Abstract
BACKGROUND VSMC proliferation and migration pathways play important roles in plaque formation in the vessel stenosis and re-stenosis processes. The microRNAs affect the expression of many genes that regulate these cellular processes. The aim of this study was to investigate the effects of miR-181b, miR-204, and miR-599 on the gene and protein expression levels of hematopoietic cell kinase (HCK) in VSMCs. METHODS miR-181b, miR-204 were predicted for the suppression of HCK in the chemokine signaling pathway using bioinformatics tools. Then, the VSMCs were transfected by PEI-containing microRNAs. The HCK gene and protein expression levels were evaluated using RT-qPCR and Western blotting techniques, respectively. Moreover, the cellular proliferation and migration were evaluated by MTT and scratch assay methods. RESULTS The miR-181b and miR-204 decreased significantly the HCK gene and (total and phosphorylated) protein expression levels. Also, the miR-599 did not show any significant effects on the HCK gene and protein levels. The data also showed that miR-181b, miR-204, and miR-599 prevent significantly the proliferation and migration of VSMCs. CONCLUSION The downregulation of HCK by miR-181b and miR-204 suppressed the VSMC proliferation and migration.

Abstract
The excessive proliferation and migration of smooth muscle cells (SMCs) play an important role in restenosis following percutaneous coronary interventions. MicroRNAs are able to target various genes and involved in the regulation of diverse cellular processes including cell growth and proliferation. In this study we investigated whether and how MicroRNAs regulated vascular SMC proliferation and vascular remodeling following carotid artery injury in mice. We showed that carotid artery injury-induced neointimal formation was remarkably ameliorated in microRNA (miR)-302 heterozygous mice and SMC-specific miR-302 knockout mice. In contrast, delivery of miR-302a adenovirus to the injured carotid artery enhanced neointimal formation. Upregulation of miR-302a enhanced the proliferation and migration of mouse aorta SMC (MASMC) in vitro by promoting cell cycle transition, whereas miR-302a inhibition caused the opposite results. Moreover, miR-302a promoted Akt activation by corporately decreasing Akt expression and increasing Akt phosphorylation in MASMCs. Application of the Akt inhibitor GSK690693 (5 μmol/L) counteracted the functions of miR-302a in promoting MASMC proliferation and migration. We further revealed that miR-302a directly targeted at the 3' untranslated region of PH domain and leucine rich repeat protein phosphatase 2 (PHLPP2) and negatively regulated PHLPP2 expression. Restoration of PHLPP2 abrogated the effects of miR-302a on Akt activation and MASMC motility. Furthermore, knockdown of PHLPP2 largely abolished the inhibition of neointimal formation that was observed in miR-302 heterozygous mice. Our data demonstrate that miR-302a exacerbates SMC proliferation and restenosis through increasing Akt signaling by targeting PHLPP2.

Abstract
Endothelial progenitor cells (EPCs) have emerged as a promising therapeutic choice for thrombi recanalization. However, this role of EPCs is confined by some detrimental factors. The aim of this study was to explore the role of the miR‐9‐5p in regulation of the proliferation, migration and angiogenesis of EPCs and the subsequent therapeutic role in thrombosis event. Wound healing, transwell assay, tube formation assay and in vivo angiogenesis assay were carried out to measure cell migration, invasion and angiogenic abilities, respectively. Western blot was performed to elucidate the relationship between miR‐9‐5p and TRPM7 in the autophagy pathway. It was found that miR‐9‐5p could promote migration, invasion and angiogenesis of EPCs by attenuating TRPM7 expression via activating PI3K/Akt/autophagy pathway. In conclusion, miR‐9‐5p, targets TRPM7 via the PI3K/Ak/autophagy pathway, thereby mediating cell proliferation, migration and angiogenesis in EPCs. Acting as a potential therapeutic target, miR‐9‐5p may play an important role in the prognosis of DVT.

MicroRNA-125a-3p affects smooth muscle cell function in vascular stenosis. J Mol Cell Cardiol 2019; 136:85-94.

Abstract
AIMS Many studies have indicated that microRNAs are closely related to the process of peripheral arterial disease (PAD). Previously, we found that microRNA-125a-3p (miR-125a-3p) in restenotic arteries after interventional therapy of lower extremity vessels was notably decreased compared with that of normal control arteries. However, its role in the development of vascular stenosis is not yet clearly understood. The purpose of this study was to investigate the expression, regulatory mechanism and function of miR-125a-3p in the process of vascular stenosis. METHODS AND RESULTS Quantitative reverse-transcription polymerase chain reaction assays indicated that miR-125a-3p in restenotic arteries after interventional therapy was significantly lower than that in normal control arteries. Immunofluorescence and in situ hybridization co-staining assays in arterial sections demonstrated that miR-125a-3p was mainly expressed in the medial smooth muscle layer. Transfection of miR-125a-3p mimics into cultured vascular smooth muscle cells (VSMCs) effectively inhibited cell proliferation and migration. Then, western blot and luciferase activity assays showed that recombinant human mitogen-activated protein kinase 1 (MAPK1) was a functional target of miR-125a-3p and was involved in miR-125a-3p-mediated cell effects. Finally, the lentiviral infection of miR-125a-3p in balloon-injured rat carotid vascular walls showed that miR-125a-3p overexpression significantly reduced the probability of neointimal membrane production. CONCLUSIONS miR-125a-3p can effectively inhibit the function of VSMCs and the occurrence of vascular stenosis by targeting MAPK1. This study introduces a new molecular mechanism of PAD. We show that regulation of the miR-125a-3p level has the potential to provide a new treatment for PAD and other proliferative vascular diseases.

Abstract
Background/aim Diabetic vascular smooth muscle cells (VSMCs) are characterized by increased proliferation and migration. Small noncoding microRNAs (miRNAs) have been considered critical modulators of the VSMC phenotypic switch after an environmental stimulus. However, microRNA in high glucose-induced proinflammation and its atherogenic effect is still ambiguous. Materials and methods The technique of qRT-PCR was used to examine the expression of miR-9 in VSMCs. The downstream signaling protein relative to miR-9 regulation, Krüppel-like factor 5, and some marker genes of contractile VSMCs were analyzed by western blotting and qRT-PCR. Luciferase reporter assay was used to detect the expression of KLF5, which is regulated by miR-9. To examine the function of a miR-9 inhibitor in VSMC proliferation and migration, VSMC proliferation and migration assays were performed. Results Reduced transcriptional levels of miR-9 and expression of specific genes of contractile VSMCs were observed in the SMC cell line C-12511 treated with high glucose and SMCs, which were isolated from db/db mice. Moreover, the activity of KLF5 3′-UTR was dramatically reduced by a miR-9 mimic and increased by a miR-9 inhibitor. The proliferation and migration of SMCs were reduced by the miR-9 mimic. Conclusion miR-9 inhibits the proliferation and migration of SMC by targeting KLF5 in db/db mice.

Abstract
BACKGROUND Atherosclerosis (AS) is a major risk factor for cardiovascular disease. microRNAs play a key role in gene regulation in the formation and development of atherosclerotic plaques. Herein, the role and target gene of miR-185 in AS were explored. MATERIALS AND METHODS Cell viability, migration and invasion were examined by cell counting kit-8 (CCK-8) and transwell assay. The relative luciferase activity was measured by luciferase reporter assay. The levels of miR-185, STIM1, vascular endothelial growth factor (VEGF) and matrix metalloprotein-9 (MMP-9) were evaluated by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blot. RESULTS The results revealed that ox-LDL decreased miR-185 expression, and enhanced STIM1 expression in MOVAS cells, as well promoted cell viability, migration and invasion. 3'-UTR of STIM1 contained miR-185 binding site according to the Targetscan. miR-185 silencing or STIM1 overexpression promoted the viability, migration and invasion of ox-LDL-induced MOVAS cells. miR-185 overexpression or STIM1 silencing had the opposite effect. Besides, miR-185 silencing up-regulated the levels of VEGF and MMP-9 in vitro, and increased the lesions of arterial wall tissues and STIM1 positive rate in vivo. However, STIM1 silencing reversed these effects. CONCLUSIONS Sum up, STIM1 was a potential target gene of miR-185 in AS. Knockdown of miR-185 facilitated the progression of AS through enhancing cell proliferation, migration and invasion via targeting STIM1. The research provides a novel view of miR-185/STIM1 axis function in AS development, and this targeting method may prevent and treat AS.

Abstract
Vascular smooth muscle cell (VSMC) proliferation plays a critical role in atherosclerosis. At the beginning of the pathologic process of atherosclerosis, irregular VSMC proliferation promotes plaque formation, but in advanced plaques VSMCs are beneficial, promoting the stability and preventing rupture of the fibrous cap. Recent studies have demonstrated that microRNAs (miRNAs) expressed in the vascular system are involved in the control of VSMC proliferation. This review summarizes recent findings on the miRNAs in the regulation of VSMC proliferation, including miRNAs that exhibit the inhibition or promotion of VSMC proliferation, and their targets mediating the regulation of VSMC proliferation. Up to now, most of the studies were performed only in cultured VSMC. While the modulation of miRNAs is emerging as a promising strategy for the regulation of VSMC proliferation, most of the effects of miRNAs and their targets in vivo require further investigation.

Abstract
Vascular smooth muscle cells (VSMCs) and endothelial cells (ECs) are crucial in vascular remodeling. They exert pivotal roles in the development and progression of atherosclerosis, vascular response to injury, and restenosis after transcatheter angioplasty. As a witness of their importance in the cardiovascular system, a large body of evidence has accumulated about the role played by micro RNAs (miRNA) in modulating both VSMCs and ECs. More recently, a growing number of long noncoding RNA (lncRNAs) came beneath the spotlights in this research field. Several mechanisms have been revealed by which lncRNAs are able to exert a relevant biological impact on vascular remodeling. The aim of this review is to provide an integrated summary of ncRNAs that exert a relevant biological function in VSMCs and ECs of the vascular wall, with emphasis on the available clinical evidence of the potential usefulness of these molecules as circulating biomarkers of in-stent restenosis.

Abstract
In this study, we investigated the role ofhistone deacetylase 4 (HDAC4) and MEG3/miR-125a-5p/interferonregulatoryfactor 1 (IRF1) on vascular smooth muscle cell (VSMCs)proliferation. Platelet derived growth factor (PDGF)-BB was used toinduce the proliferation and migration of VSMCs. The expressionsof MEG3, miR-125a-5p, HDAC4 and IRF1in VSMCs were detectedby qRT-PCR and western blot, respectively. ChIP assay was usedto determine the relationship between MEG3 and HDAC4. Doubleluciferase reporter assay was used to test the regulation betweenmiR-125-5p and IRF1. Results showed that PDGF-BB decreasedthe expression of MEG3 and IRF1, while increased the expressionof miR-125a-5p and HDAC4. In addition, HDAC4 knockdowninhibited the proliferation and migration of VSMCs via upregulatingMEG3 and downregulating miR-125a-5p. MiR-125a-5p inhibitorcould repress the proliferation and migration of VSMCs andalleviate intimal hyperplasia (IH) by directly upregulating IRF1expression. These results suggested that HDAC4 interferenceinhibited PDGF-BB-induced VSMCs proliferation via regulatingMEG3/miR-125a-5p/IRF1 axis, and then alleviated IH.
