Abstract
Background: In stent restenosis (ISR) is one of the major complications after stent implantation. Thus, there is a growing interest in identifying a biomarker for the onset of ISR. High levels of serum homocysteine (Hcy) have been associated with the progression of cardiovascular disease. Therefore, the study was carried out to quantify the correlation between serum Hcy and ISR severity. Compared with coronary angiography (CAG), Hcy levels provided a significantly better clinical detection of ISR severity after PCI. Methods: A total of 155 patients were recruited from Shanxi Bethune hospital, from 6 months to 2 years post PCI. Serum Hcy levels and postoperative angiography results were used to differentiate the patients into two experimental groups: ISR (>50% diametrical stenosis), and non-ISR. The non-ISR included two subgroups: intimal hyperplasia (10–50% diametrical stenosis), and recovery (<10% diametrical stenosis). In addition, a group of 80 healthy individuals was used as a negative control. The correlation between homocysteine level and ISR severity t was analyzed for all groups. In addition, the correlation between serum Hcy level and the severity of ISR in the experimental group was analyzed by the Pearson correlation test. Results: The serum Hcy level in the experimental group and control group was determined to be (20.21 ± 11.42) μmol/L and (15.11 ± 10.25) μmol/L respectively. The level of serum Hcy in the experimental group was significantly higher than in the control group (t-value of 2.385; p-value of 0.019). The serum Hcy level in the restenosis and the intimal hyperplasia group was (25.72 ± 13.71) μmol/L and (17.35 ± 7.70) μmol/L respectively. The serum Hcy level in the restenosis group was significantly higher than in the intimal hyperplasia group (t-value of 2.215; p-value of 0.033). The level of serum Hcy in the group without a plaque in the stent was (16.30 ± 6.08) μmol/L, whereas in the control group was (15.11 ± 10.25) μmol/L. The no plaque group had a slightly higher serum Hcy level than the control group (t-value of 0.634; p-value of 0.528). All included patients were divided into four quartiles based on the serum Hcy concentration: quartile 1 (8.90–13.20 μmol/L), quartile 2 (13.30–16.45 μmol/L), quartile 3 (16.60–24.25 μmol/L) and quartile 4 (24.30-65.30 μ mol/L). The incidence of ISR was 5, 6.25, 7.5 and 15%, in the 1,2,3 and four quartiles respectively. The serum Hcy level in the experimental group was (20.21 ± 11.42) μmol/L, the severity of in-stent restenosis was (0.25 ± 0.31), (R-value was 0.234; p-value was 0.037), indicating a correlation between serum Hcy and the severity of restenosis (p < 0.05). Taking coronary angiography as the gold standard, a ROC curve analysis was performed on the serum Hcy levels for the experimental group. The area under the curve (AUC) was 0.718 (95% CI 0.585-0.854, p < 0.001), indicating that the serum Hcy concentration could predict ISR. On the ROC curve, the best critical value of serum Hcy concentration for predicting ISR was 20.05 μmol/L, with a sensitivity of 45% and specificity of 88.1%. Conclusion: A positive correlation was observed between homocysteine and the severity of restenosis after PCI, The level of Hcy could serve as a predictive biomarker for the severity of ISR.

Long Non-Coding RNAs Might Regulate Phenotypic Switch of Vascular Smooth Muscle Cells Acting as ceRNA: Implications for In-Stent Restenosis. Int J Mol Sci 2022; 23:ijms23063074. [PMID: 35328496 PMCID: PMC8952224 DOI: 10.3390/ijms23063074] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 03/07/2022] [Accepted: 03/09/2022] [Indexed: 02/01/2023] Open
Abstract
Coronary in-stent restenosis is a late complication of angioplasty. It is a multifactorial process that involves vascular smooth muscle cells (VSMCs), endothelial cells, and inflammatory and genetic factors. In this study, the transcriptomic landscape of VSMCs’ phenotypic switch process was assessed under stimuli resembling stent injury. Co-cultured contractile VSMCs and endothelial cells were exposed to a bare metal stent and platelet-derived growth factor (PDGF-BB) 20 ng/mL. Migratory capacity (wound healing assay), proliferative capacity, and cell cycle analysis of the VSMCs were performed. RNAseq analysis of contractile vs. proliferative VSMCs was performed. Gene differential expression (DE), identification of new long non-coding RNA candidates (lncRNAs), gene ontology (GO), and pathway enrichment (KEGG) were analyzed. A competing endogenous RNA network was constructed, and significant lncRNA–miRNA–mRNA axes were selected. VSMCs exposed to “stent injury” conditions showed morphologic changes, with proliferative and migratory capacities progressing from G0-G1 cell cycle phase to S and G2-M. RNAseq analysis showed DE of 1099, 509 and 64 differentially expressed mRNAs, lncRNAs, and miRNAs, respectively. GO analysis of DE genes showed significant enrichment in collagen and extracellular matrix organization, regulation of smooth muscle cell proliferation, and collagen biosynthetic process. The main upregulated nodes in the lncRNA-mediated ceRNA network were PVT1 and HIF1-AS2, with downregulation of ACTA2-AS1 and MIR663AHG. The PVT1 ceRNA axis appears to be an attractive target for in-stent restenosis diagnosis and treatment.

Abstract
Background Endothelial cell-specific molecule 1 (ESM-1 or endocan) is an immunoinflammatory marker strongly associated with inflammation, vascular endothelial dysfunction and atherosclerosis. We explored the relationship between serum endocan concentrations and coronary in-stent restenosis (ISR). Methods Fifty consecutive patients with ISR and 50 control subjects were included in this study. Clinical data and angiographic characteristics were collected. Serum endocan concentrations were measured using an enzyme-linked immunosorbent assay. Results All included patients were divided into four quartiles based on their concentrations of endocan: quartile 1 (0.62-1.31 ng/mL), quartile 2 (1.33-1.74 ng/mL), quartile 3 (1.75-2.77 ng/mL) and quartile 4 (2.78-4.24 ng/mL). The rates of ISR were 16%, 24%, 68%, and 92%, respectively. The patients in quartile 4 had significantly higher rates of ISR than the other groups (p < 0.001). Logistic regression analysis indicated that endocan concentration [odds ratio = 8.65, 95% confidence interval 3.56-20.94; p < 0.001] was an independent predictor of ISR. Receiver operating characteristic curve analysis was used to explore the relationship between endocan and ISR. Using a cutoff value of 1.625 ng/mL, endocan predicted ISR with a sensitivity of 86% and a specificity of 78%. Conclusions Our findings suggest that plasma endocan levels may be a novel biomarker of endothelial dysfunction in patients with ISR.

Abstract
Lentiviral expression vectors for calcitonin gene-related peptide (CGRP) were used to transfect rat bone marrow mesenchymal stem cells (MSCs). After assessing the biological characteristics of proliferation and aging in MSCs transfected with CGRP, we observed the effects of the CGRP-modified rat MSCs on the migration and proliferation of rat vascular smooth muscle cells (VSMCs) in vitro. Rat MSCs were isolated, cultured in vitro, and identified by flow cytometry. A CGRP recombinant lentivirus was transfected into MSCs. The transfection efficiency was determined by fluorescence microscopy and flow cytometry, and CGRP in MSCs was detected by real-time quantitative PCR, ELISA, and immunofluorescence. The proliferation and senescence of CGRP-modified MSCs were evaluated by MTT assay and beta-galactosidase staining. VSMCs were isolated, cultured in vitro, and identified by immunofluorescence. CGRP-modified MSCs and VSMCs were cocultured in a Transwell system. The proliferation and migration of VSMCs were evaluated by scratch testing and the MTT method. Rat bone marrow MSCs showed a spindle-shaped morphology, adherent growth in vitro, positive CD29 and CD90 expression, and negative CD45 expression. CGRP was stably expressed in MSCs after 48 h of recombinant lentivirus transfection. CGRP mRNA and protein secretion in CGRP recombinant lentivirus-transfected MSCs were higher than that in control MSCs. Immunofluorescence showed that CGRP protein could be expressed in CGRP-modified MSCs. The proliferation ability and senescence rates did not differ between lentivirus-transfected MSCs and untransfected MSCs. Rat VSMCs expressed α-SMA protein and exhibited a spindle-shaped morphology and adherent growth in vitro. In Transwell coculture experiments, scratch testing of VSMCs showed that CGRP-modified MSCs could reduce VSMC proliferation and migration. The CGRP gene can be stably expressed in MSCs after CGRP recombinant lentivirus transfection. CGRP recombinant lentivirus transfection has little effect on the proliferation or senescence of MSCs, and CGRP-modified MSCs can inhibit the proliferation and migration of VSMCs. These results lay a foundation for research on the use of CGRP gene-engineered MSCs in restenosis therapy.

Abstract
The present study was conducted to determine the correlation between high perfusion syndrome and stent restenosis after cerebral vascular stent implantation. A total of 146 patients diagnosed with cerebral vascular stenosis and stent implantation were selected. A total of 55 cases (37.67%) of cerebral hyperperfusion syndrome patients were diagnosed by xenon-enhanced computer tomography (Xe-CT) examination and clinical symptoms within 3 days after surgery and were chosen as the observation group. A total of 91 cases were selected as the control group. After treatment, blood flow of the anterior cerebral artery, middle cerebral artery, posterior cerebral artery, anterior border zone, posterior border zone and the inner border zone of the two groups increased, with values in the observation group increasing more significantly, and the differences were statistically significant (P<0.05). The rate of restenosis and target lesion diameter one month and one year after operation in the observation group were significantly higher than those in the control group (P<0.05). Multivariate logistic regression analysis showed that the mean systolic blood pressure (mSBP), mean diastolic blood pressure (mDBP), stenosis rate of cerebral vascular diameter and high perfusion syndrome were independent risk factors for restenosis (P<0.05). The application of Xe-CT examination is important for early diagnosis of hyperperfusion syndrome. Hyperperfusion syndrome and the occurrence of stent restenosis are closely related. mSBP, mDBP, cerebral blood vessel diameter stenosis rate and high perfusion comprehensive syndrome are the independent risk factors of restenosis.

Abstract
Smooth muscle cells (SMCs) are key regulators of vascular disease and circulating smooth muscle progenitor cells may play important roles in vascular repair or remodelling. We developed enhanced protocols to derive smooth muscle progenitors from murine bone marrow and tested whether factors that are increased in atherosclerotic plaques, namely platelet-derived growth factor-BB (PDGF-BB) and monomeric collagen, can influence the smooth muscle specific differentiation, proliferation, and survival of mouse bone marrow-derived progenitor cells. During a 21 day period of culture, bone marrow cells underwent a marked increase in expression of the SMC markers α-SMA (1.93 ± 0.15 vs. 0.0008 ± 0.0003 (ng/ng GAPDH) at 0 d), SM22-α (1.50 ± 0.27 vs. 0.005 ± 0.001 (ng/ng GAPDH) at 0 d) and SM-MHC (0.017 ± 0.004 vs. 0.001 ± 0.001 (ng/ng GAPDH) at 0 d). Bromodeoxyuridine (BrdU) incorporation experiments showed that in early culture, the smooth muscle progenitor subpopulation could be identified by high proliferative rates prior to the expression of smooth muscle specific markers. Culture of fresh bone marrow or smooth muscle progenitor cells with PDGF-BB suppressed the expression of α-SMA and SM22-α, in a rapidly reversible manner requiring PDGF receptor kinase activity. Progenitors cultured on polymerized collagen gels demonstrated expression of SMC markers, rates of proliferation and apoptosis similar to that of cells on tissue culture plastic; in contrast, cells grown on monomeric collagen gels displayed lower SMC marker expression, lower growth rates (319 ± 36 vs. 635 ± 97 cells/mm2), and increased apoptosis (5.3 ± 1.6% vs. 1.0 ± 0.5% (Annexin 5 staining)). Our data shows that the differentiation and survival of smooth muscle progenitors are critically affected by PDGF-BB and as well as the substrate collagen structure.

Abstract
OBJECT Percutaneous Coronary Intervention (PCI) is one of the most effective treatments for Coronary Heart Disease (CHD), but the high rate of In Stent Restenosis (ISR) has plagued clinicians after PCI. We aim to investigate the correlation of plasma Stromal Interaction Molecular 1 (STIM1) and Osteoprotegerin (OPG) level with stent restenosis after PCI. METHODS A total of 100 consecutive patients with Coronary Heart Disease (CHD) received PCI procedure were recruited. Coronary angiography was performed 8 months after their PCI. Then patients were divided into 2 groups: observation group was composed by patients who existing postoperative stenosis after intervention; Control group was composed by patients with no postoperative stenosis. The plasma levels of STIM, OPG in all patients were tested before and after intervention. Pearson correlation and multiple linear regression analysis were performed to analysis the correlation between STIM, OPG level and postoperative stenosis. RESULTS 35 cases were divided into observation group and other 65 were divided into control group. The plasma levels of STIM, OPG have no statistical difference before their PCI procedure, but we observed higher level of High-sensitivity C-reactive protein (Hs-CRP) existed in observation group. We observed higher level of plasma STIM, OPG in observation group when compared with control group after PCI procedure (P < 0.05). Regression analysis demonstrated that Hs-CRP, STIM1, OPG are independent risk factors for ISR. CONCLUSION Elevated levels of plasma STIM1, OPG are independent risk factors for ISR in patients received PCI, which could provide useful information for the restenosis control after PCI.

Abstract
BACKGROUND Coronary intimal hyperplasia occurs at the site of spasm in patients with vasospastic angina. The migration of vascular smooth muscle cells (VSMCs) from the media has been proposed as a potential mechanism; however, this has not been confirmed with supportive evidence. OBJECTIVE To determine which cell types participate in spasm-induced coronary intimal hyperplasia. METHODS Morphological changes in spastic coronary artery segments in beagles were examined using electron microscopy and immunohistochemical staining of cell markers at 1 h, 3 h and 6 h, and two and four weeks after spasm provocation. RESULTS Small smooth muscle-like cells (SMLCs) were observed in the media of nonspastic coronary segments using electron microscopy. These cells attached side-to-side to large, known VSMCs. At 1 h to 6 h after spasm provocation, SMLCs separated from VSMCs, changed to an amoebic configuration and migrated through cleaved junctions or disrupted portions of the internal elastic lamina into the subendothelial space. The SMLCs expressed alpha-smooth muscle actin and N-cadherin, but not smooth muscle myosin heavy chain-1 and β-actin, suggesting that they were myofibroblasts and not a synthetic phenotype of VSMCs. Intimal hyperplasia was observed in all preparations at two and four weeks after spasm provocation. Furthermore, alpha-smooth muscle actin-positive SMLCs, often amoebic in configuration, were observed in the hyperplastic intima. CONCLUSIONS On coronary spasm provocation, SMLCs (ie, possible myofibroblasts) resident in the media migrate as a spearhead into the intima and play a role in coronary intimal hyperplasia.

Abstract
Since the percutaneous transtuminal coronary angioplasty was introduced into China in 1984, this procedure has become widely accepted as an important step in coronary revascularization. This study shows the effect of the monoclonal antibody (mAb) on the platelet glycoprotein IIIa receptor during endothelialization and in-stent restenosis by implanting the mAb-eluting stents into iliac arteries of rabbits. The hard tissue cross sections of the stent-implanted arterial segments were made by polymethylmethacrylate embedding. Arterial intima proliferation was observed and analyzed. The endothelialization of the stent surface was observed using scanning electron microscope, whereas the ultrastructure of the neointima was observed using transmission electron microscope. After one month of stent implantation, the surfaces of both groups were covered by intact endothelial layers, but the neointimal areas and the ratio of stenosis were significantly lesser in the mAb-eluting stent group (p < 0.01). After 3 months, the ratio of stenosis in the mAb-eluting stent group was 14.67 ± 0.79, whereas that of the bare stent group was 21.58 ± 1.76 (p < 0.01). Therefore, the mAb eluting from the stent surface has the potential to accelerate endothelialization, prevent thrombosis formation due to the interaction of stent with blood, and decrease the stenosis ratio by inhibiting neointima proliferation.
