Abstract
Objective Our recently published study discovers that exosomal microRNA (miR)-186-5p promotes vascular smooth muscle cell viability and invasion to facilitate atherosclerosis. This research aimed to explore the prognostic implication of serum exosomal miR-186-5p in acute myocardial infarction (AMI) patients receiving percutaneous coronary intervention (PCI). Methods One hundred and fifty AMI patients receiving PCI and 50 healthy controls (HCs) were screened. Serum exosomal miR-186-5p was detected by reverse transcriptase-quantitative polymerase chain reaction assay in AMI patients at admission and after PCI, as well as in HCs after enrollment. Major adverse cardiac events (MACE) were recorded during follow-up in AMI patients receiving PCI. Results Serum exosomal miR-186-5p was raised in AMI patients vs. HCs (P < 0.001). Besides, serum exosomal miR-186-5p was positively linked to body mass index (P = 0.048), serum creatinine (P = 0.021), total cholesterol (P = 0.029), and C-reactive protein (P = 0.018); while it was reversely linked with estimated glomerular filtration rate (P = 0.023) in AMI patients. Interestingly, serum exosomal miR-186-5p was correlated with the diagnosis of ST-segment elevation myocardial infarction (P = 0.034). Notably, serum exosomal miR-186-5p was decreased after PCI vs. at admission (P < 0.001). The 6-, 12-, 18-, and 24-month accumulating MACE rates were 4.5%, 8.9%, 14.8%, and 14.8% in AMI patients. Furthermore, serum exosomal miR-186-5p ≥3.39 (maximum value in HCs) after PCI (P = 0.021) and its decrement percentage Conclusion Serum exosomal miR-186-5p is reduced after PCI, and its post-PCI high level or minor decrease estimates increased MACE risk in AMI patients.

Abstract
OBJECTIVE To analyze the significance of serum miR-145 and miR-210 expression levels in the diagnosis of carotid artery stenosis. METHODS During the same period, 55 healthy individuals who received physical examination in the same hospital were recruited as controls and assigned to a non-stenosis group. Among the included patients, there were 45 cases of mild stenosis, 14 cases of moderate stenosis, and 6 cases of severe stenosis after carotid color Doppler ultrasonography. The expression levels of miR-145 and miR-210 in serum were measured using real-time fluorescence quantitative polymerase chain reaction (qPCR) technology. RESULTS The expression levels of serum miR-145 and miR-210 in carotid artery stenosis group were significantly lower than those in non-stenosis group (p < 0.001). Multivariate Logistic regression analysis showed that smoking history, diabetes, hypertension and total cholesterol were positively correlated with the occurrence of carotid artery stenosis (p < 0.05). The expression levels of miR-145 and miR-210 were significantly negatively correlated with carotid artery stenosis (p < 0.001). In addition, patients with carotid artery stenosis and low expression levels of miR-145 and miR-210 had a greater risk of cerebral ischemia (p < 0.05). Cox regression analysis showed that the low expression of miR-145 and miR-210 were independent predictors of cerebral ischemic events. ROC analysis confirmed that miR-145 and miR-210 had good diagnostic efficacy in cerebral ischemia (p < 0.001). CONCLUSION The decreased expression of miR-145 and miR-210 in serum is closely related to the diagnostic significance of carotid artery stenosis, and may be used to predict the occurrence of cerebral ischemic events.

Int J Mol Sci 2023; 24:14325. [PMID: 37762627 PMCID: PMC10531661 DOI: 10.3390/ijms241814325] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 09/18/2023] [Accepted: 09/18/2023] [Indexed: 09/29/2023] Open
Abstract
Atherothrombotic stroke represents approximately 20% of all ischemic strokes. It is caused by large-artery atherosclerosis, mostly in the internal carotid artery, and it is associated with a high risk of early recurrence. After an ischemic stroke, tissue plasminogen activator is used in clinical practice, although it is not possible in all patients. In severe clinical situations, such as high carotid stenosis (≥70%), revascularization by carotid endarterectomy or by stent placement is carried out to avoid recurrences. In stroke prevention, the pharmacological recommendations are based on antithrombotic, lipid-lowering, and antihypertensive therapy. Inflammation is a promising target in stroke prevention, particularly in ischemic strokes associated with atherosclerosis. However, the use of anti-inflammatory strategies has been scarcely studied. No clinical trials are clearly successful and most preclinical studies are focused on protection after a stroke. The present review describes novel therapies addressed to counteract inflammation in the prevention of the first-ever or recurrent stroke. The putative clinical use of broad-spectrum and specific anti-inflammatory drugs, such as monoclonal antibodies and microRNAs (miRNAs) as regulators of atherosclerosis, will be outlined. Further studies are necessary to ascertain which patients may benefit from anti-inflammatory agents and how.

Abstract
Purpose Carotid artery restenosis (CAS) is a leading contributor to cerebrovascular diseases and one of the leading causes of death in the world. The purpose of this study was to assess the predictive efficiency of long non-coding RNA (lncRNA) TNFalpha-and hnRNP L-related immunoregulatory lncRNA (THRIL) and its association with the pathogenesis of CAS. Patients and Methods The expression of THRIL was determined in patients with asymptomatic CAS and human aortic endothelial cell (HAEC) models induced by oxidized low-density lipoprotein (ox-LDL). The receiver operating characteristic (ROC) curve and Kaplan-Meier (K-M) drawings were constructed to predict the risk of poor prognosis in patients with CAS. The cell proliferation, death rate, and inflammation were detected by 3-(4,5-dimethyl-2-thiazyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT), flow cytometry, and enzyme-linked immunosorbent assay (ELISA) assays. Results The relative expression of THRIL was elevated in patients with asymptomatic CAS. The findings of ROC curve indicated that THRIL had a predictive possibility on CAS. K-M finding and Cox regression analysis showed that the expression of THRIL and the degree of CAS were independent risk factors for poor prognosis in patients with CAS. THRIL was up-expressed in HAECs induced by ox-LDL. Down-regulation of THRIL could promote the proliferation of HAECs, inhibit cell apoptosis, and restrict cell inflammation. Conclusion THRIL was a diagnostic and prognostic biomarker in CAS and played an important role in regulating the proliferation, apoptosis, and inflammation of HAECs induced by ox-LDL.

Abstract
Previous studies have shown that micro-RNA (miR)-186-5p can affect apoptosis of cells by regulating insulin-like growth factor-I (IGF-1). However, the role of miR-186-5p-IGF1 axis in traumatic brain injury (TBI), especially oxidative stress and neuroinflammatory response, remains to be further studied. Lipopolysaccharide (5 μg/mL) was used to activate microglia in vitro . The expression of miR-186-5p, IGF-1 was detected by quantitative reverse transcription PCR (qRT-PCR). ELISA and western blot were used to detect the inflammatory factors and oxidative stress. Western blot was used to detect apoptotic proteins (Bax, Bcl2 and C-caspase3), inflammatory proteins (iNOS and COX2), oxidative stress proteins (Nrf2 and HO-1) and NLRP3/apoptosis-associated speck-like protein containing a CARD (ASC)/caspase-1 inflammatory bodies. MiR-186-5p inhibitor could reduce the inflammatory factors and oxidative stress in BV2 treated with lipopolysaccharide, and reduce apoptosis. In addition, we also found that inhibition of miR-186-5p increased the expression of IGF-1, which is necessary for nervous system development. Luciferase activity assay confirmed that IGF-1 was the direct target gene of miR-186-5p. Inhibiting miR-186-5p, through upregulation IGF-1, attenuates the inflammatory factors, oxidative stress and by inhibiting NLRP3/ASC/caspase-1 signal pathway TBI in-vitro model.

Abstract
Atheromatous disease is the first cause of death and dependency in developed countries and carotid artery atherosclerosis is one of the main causes of severe ischaemic strokes. Current management strategies are mainly based on the degree of stenosis and patient selection has limited accuracy. This information could be complemented by the identification of biomarkers of plaque vulnerability, which would permit patients at greater and lesser risk of stroke to be distinguished, thus enabling a better selection of patients for surgical or intensive medical treatment. Although several circulating protein-based biomarkers with significance for both the diagnosis of carotid artery disease and its prognosis have been identified, at present, none have been clinically implemented. This review focuses especially on the most relevant clinical parameters to take into account in routine clinical practice and summarises the most up-to-date data on epigenetic biomarkers of carotid atherosclerosis and plaque vulnerability.

Abstract
LncRNA five prime to Xist (FTX) has been identified to exert a protective effect in multiple diseases. However, whether and how FTX attenuates cerebral ischemia-reperfusion injury (CI/RI) is still unclear. To simulate CI/RI, an in vitro oxygen-glucose deprivation/reoxygenation (OGD/R) HT22 cell model and an in vivo middle cerebral artery occlusion/reperfusion (MCAO/R) Sprague-Dawley rat model were respectively constructed. In CI/RI plasma samples, OGD/R-challenged HT22 cells, and brain tissues from MCAO/R rats, FTX and mouse double minute 4 (MDM4) expressions were substantially decreased while miR-186-5p abundance was evidently increased. It was also revealed that FTX obviously improved neuronal damage induced by OGD/R through increasing proliferation, reducing apoptosis, and alleviating oxidative stress in OGD/R-challenged HT22 cells. Additionally, FTX positively regulated MDM4 level in OGD/R-treated HT22 cells as a sponge of miR-186-5p. Moreover, miR-186-5p upregulation or MDM4 suppression restored the inhibitory effects of FTX upregulation on OGD/R-triggered neuronal damage in HT22 cells. Therefore, these results suggest that FTX might ameliorate CI/RI by regulating the miR-186-5p/MDM4 pathway, providing a new target for stroke impairment treatment.

Abstract
MicroRNAs (miRNAs/miRs) may be used as novel promising diagnostic and prognostic biomarkers for various diseases, including asymptomatic carotid artery stenosis (ACAS). The present study aimed to investigate the abnormal expression of microRNA-483-5p (miR-483-5p) in patients with ACAS and to evaluate its diagnostic value for ACAS screening and its predictive value for cerebrovascular events. A total of 128 patients with ACAS and 76 healthy controls were included in the present study. The expression of miR-483-5p in serum was measured by reverse transcription-quantitative PCR. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of miR-483-5p in patients with ACAS. Kaplan-Meier curves were drawn and Cox regression analysis was used to determine the predictive value of miR-483-5p for cerebrovascular events in patients with ACAS. Serum miR-483-5p levels were significantly increased in patients with ACAS as compared with those in healthy controls. The expression of miR-483-5p was significantly associated with diabetes (P=0.011), dyslipidemia (P=0.047) and the degree of carotid stenosis (P=0.006) in patients with ACAS. In addition, the area under the ROC curve was 0.910, with a sensitivity of 80.5% and a specificity of 89.5% at the cutoff value of 0.705, indicating that serum miR-483-5p expression has a certain diagnostic value in patients with ACAS. Furthermore, the patients with high miR-483-5p expression had a higher proportion of cerebrovascular events than patients with low miR-483-5p levels (log-rank P=0.011) and miR-483-5p was an independent prognostic marker for predicting the occurrence of cerebrovascular events in patients with ACAS. The results indicated that miR-483-5p expression is significantly increased in patients with ACAS and that abnormal miR-483-5p expression may be a candidate biomarker for ACAS diagnosis and the prediction of cerebrovascular event occurrence.

Abstract
OBJECTIVES Abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) are involved in carotid artery stenosis. The purpose of this study was to investigate the diagnostic value of serum miR-28-5p in asymptomatic carotid artery stenosis and its regulation on the proliferation and migration of VSMCs. METHODS Serum miR-28-5p levels in 65 healthy controls and 68 asymptomatic carotid artery stenosis patients were detected by qRT-PCR. The receiver-operating characteristic curve was applied to elucidate the diagnostic value of serum miR-28-5p for carotid artery stenosis patients. The specificity of miRNA targets was detected by luciferase reporter assay. CCK-8 and Transwell assay were applied to detect proliferation and migration of cells. Pearson correlation test was used to investigate the correlation between Forkhead box subclass O 1 (FOXO1) and serum miR-28-5p. RESULTS Serum miR-28-5p was significantly reduced in asymptomatic carotid artery stenosis patients. Moreover, miR-28-5p could distinguish asymptomatic carotid artery stenosis patients from healthy controls, with sensitivity and specificity of 86.8% and 81.5%, respectively, indicating its high diagnostic value. The overexpression of miR-28-5p inhibited the proliferation and migration of VSMCs, while inhibition of miR-28-5p resulted in the opposite effect. What is more, FOXO1, a direct target of miR-28-5p, was significantly increased in asymptomatic carotid artery stenosis patients. Inhibition of miR-28-5p in VSMCs reversed the reduction of FOXO1 levels in patients. CONCLUSIONS miR-28-5p is a valuable diagnostic biomarker for asymptomatic carotid artery stenosis and can affect the proliferation and migration of VSMCs by regulating FOXO1.
