Abstract
MicroRNAs are short non-coding RNA molecules that function as critical regulators of various biological processes through negative regulation of gene expression post-transcriptionally. Recent studies have indicated that microRNAs are potential biomarkers for ischemic stroke. In this review, we first illustrate the pathogenesis of ischemic stroke and demonstrate the biogenesis and transportation of microRNAs from cells. We then discuss several promising microRNA biomarkers in ischemic stroke in a context-specific manner from three dimensions: biofluids selection for microRNA extraction (Where), the timing of sample collection after ischemic stroke onset (When), and the clinical application of the differential-expressed microRNAs during stroke pathophysiology (What). We show that microRNAs have the utilities in ischemic stroke diagnosis, risk stratification, subtype classification, prognosis prediction, and treatment response monitoring. However, there are also obstacles in microRNA biomarker research, and this review will discuss the possible ways to improve microRNA biomarkers. Overall, microRNAs have the potential to assist clinical treatment, and developing microRNA panels for clinical application is worthwhile.

Abstract
Objective To explore the clinical efficacy and safety of edaravone dexborneol combined with tirofiban in the treatment of acute cerebral infarction. Methods This is a retrospective study. A total of 80 patients with acute cerebral infarction (ACI) treated in Cangzhou People's Hospital from March 2018 to December 2021 were selected, and randomly divided into the routine group(n=40) and intervention group(n=40) according to the principle of random draw. Neurological deficits in the two groups were evaluated and compared before and after treatment using the National Institutes of Health Stroke Scale (NIHSS). The quality of life of the patients was evaluated by the modified Rankin Scale (mRS). Results Before treatment, NIHSS and mRS scores of the two groups were not statistically significant(p>0.05); the levels of Vmin and Qmin in the two groups showed no statistical significance(p>0.05); no statistical significance was found in CRP or IL-6 levels between the two groups(p>0.05). After treatment for 14 days, the NIHSS and mRS scores of the two groups both decreased, which was more significant in the intervention group(p<0.05); Vmin and Qmin levels increased in both groups, which was more obvious in the intervention group(p<0.05); CRP and IL-6 levels reduced in both groups, which was more remarkable in the intervention group(p<0.05). The incidences of relevant adverse drug reactions presented no differences between the two groups during treatment(p>0.05). Conclusion Edaravone dexborneol combined with tirofiban in the treatment of ACI can effectively improve patients' neurological deficits, quality of life and cerebral blood flow, and reduce inflammatory factor levels, have significant clinical efficacy and high clinical treatment safety.

[PMID: 37198572 DOI: 10.1186/s12891-023-06473-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 04/27/2023] [Indexed: 05/19/2023] Open
Abstract
BACKGROUND To explore the effect and mechanism of action of miR-210 on postmenopausal osteoporosis (PMPO) in ovariectomized rats in vivo. METHODS An ovariectomized (OVX) rat model was established by ovariectomy. Tail vein injection was performed to overexpress and knock down miR-210 in OVX rats, followed by the collection of blood and femoral tissues from each group of rats. And quantitative real-time polymerase chain reaction (qRT-PCR) was applied to assess the expression level of miR-210 in femoral tissues of each group. Micro computed tomography (Micro CT) was adopted to scan the microstructure of the femoral trabecula in each group to obtain relevant data like bone mineral density (BMD), bone mineral content (BMC), trabecular bone volume fraction (BV/TV), trabecular thickness (Tb.Th), bone surface-to-volume ratio (BS/BV), and trabecular separation (Tb.Sp). ELISA was used for determining the level of bone alkaline phosphatase (BALP), amino-terminal propeptide of type I procollagen (PINP), osteocalcin (OCN), and C-terminal telopeptide of type I collagen (CTX-1) in serum; and Western blot for the protein level of Runt-related transcription factor 2 (Runx2), osteopontin (OPN), and collagen type I alpha 1 (COL1A1) in femoral tissues. RESULTS MiR-210 expression was significantly decreased in femoral tissues of OVX rats. Overexpression of miR-210 could obviously increase BMD, BMC, BV/TV and Tb.Th, whereas significantly decrease BS/BV and Tb.Sp in femurs of OVX rats. Moreover, miR-210 also downregulated BALP and CTX-1 level, upregulated PINP and OCN level in the serum of OVX rats promoted the expression of osteogenesis-related markers (Runx2, OPN and COL1A1) in the femur of OVX rats. Additionally, further pathway analysis revealed that high expression of miR-210 activated the vascular endothelial growth factor (VEGF)/Notch1 signaling pathway in the femur of OVX rats. CONCLUSION High expression of miR-210 may improve the micromorphology of bone tissue and modulate bone formation and resorption in OVX rats by activating the VEGF/Notch1 signaling pathway, thereby alleviating osteoporosis. Consequently, miR-210 can serve as a biomarker for the diagnosis and treatment of osteoporosis in postmenopausal rats.

MicroRNA-210 Downregulates TET2 (Ten-Eleven Translocation Methylcytosine Dioxygenase 2) and Contributes to Neuroinflammation in Ischemic Stroke of Adult Mice. Stroke 2023; 54:857-867. [PMID: 36734233 PMCID: PMC10151037 DOI: 10.1161/strokeaha.122.041651] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Accepted: 12/16/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Stroke is a leading cause of morbidity and mortality worldwide. Neuroinflammation plays a key role in acute brain injury of ischemic stroke. MicroRNA-210 (miR210) is the master hypoxamir and regulates microglial activation and inflammation in a variety of diseases. In this study, we uncovered the mechanism of miR210 in orchestrating ischemic stroke-induced neuroinflammation through repression of TET2 (ten-eleven translocation methylcytosine dioxygenase 2) in the adult mouse brain. METHODS Ischemic stroke was induced in adult WT (wild type) or miR210 KO (miR210 deficient) mice by transient intraluminal middle cerebral artery occlusion. Injection of TET2 silencing RNA or miR210 complementary locked nucleic acid oligonucleotides, or miR210 KO mice were used to validate miR210-TET2 axis and its role in ischemic brain injury. Furthermore, the effect of TET2 overexpression on miR210-stimulated proinflammatory cytokines was examined in BV2 microglia. Post assays included magnetic resonance imaging scan for brain infarct size; neurobehavioral tests, reverse transcription-quantitative polymerase chain reaction, and Western blot for miR210; and TET2 levels, flow cytometry, and ELISA for neuroinflammation in the brain after stroke or microglia in vitro. RESULTS miR210 injection significantly reduced TET2 protein abundance in the brain, while miR210 complementary locked nucleic acid oligonucleotides or miR210 KO preserved TET2 regardless of ischemic brain injury. TET2 knockdown reversed the protective effects of miR210 inhibition or miR210 KO on ischemic stroke-induced brain infarct size and neurobehavioral deficits. Moreover, flow cytometry and ELISA assays showed that TET2 knockdown also significantly dampened the anti-inflammatory effect of miR210 inhibition on microglial activation and IL (interleukin)-6 release after stroke. In addition, overexpression of TET2 in BV2 microglia counteracted miR210-induced increase in cytokines. CONCLUSIONS miR210 inhibition reduced ischemic stroke-induced neuroinflammatory response via repression of TET2 in the adult mouse brain, suggesting that miR210 is a potential treatment target for acute brain injury after ischemic stroke.

A systematic review of the research progress of non-coding RNA in neuroinflammation and immune regulation in cerebral infarction/ischemia-reperfusion injury. Front Immunol 2022; 13:930171. [PMID: 36275741 PMCID: PMC9585453 DOI: 10.3389/fimmu.2022.930171] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 08/08/2022] [Indexed: 11/15/2022] Open
Abstract
Cerebral infarction/ischemia-reperfusion injury is currently the disease with the highest mortality and disability rate of cardiovascular disease. Current studies have shown that nerve cells die of ischemia several hours after ischemic stroke, which activates the innate immune response in the brain, promotes the production of neurotoxic substances such as inflammatory cytokines, chemokines, reactive oxygen species and − nitrogen oxide, and mediates the destruction of blood-brain barrier and the occurrence of a series of inflammatory cascade reactions. Meanwhile, the expression of adhesion molecules in cerebral vascular endothelial cells increased, and immune inflammatory cells such as polymorphonuclear neutrophils, lymphocytes and mononuclear macrophages passed through vascular endothelial cells and entered the brain tissue. These cells recognize antigens exposed by the central nervous system in the brain, activate adaptive immune responses, and further mediate secondary neuronal damage, aggravating neurological deficits. In order to reduce the above-mentioned damage, the body induces peripheral immunosuppressive responses through negative feedback, which increases the incidence of post-stroke infection. This process is accompanied by changes in the immune status of the ischemic brain tissue in local and systemic systems. A growing number of studies implicate noncoding RNAs (ncRNAs) as novel epigenetic regulatory elements in the dysfunction of various cell subsets in the neurovascular unit after cerebral infarction/ischemia-reperfusion injury. In particular, recent studies have revealed advances in ncRNA biology that greatly expand the understanding of epigenetic regulation of immune responses and inflammation after cerebral infarction/ischemia-reperfusion injury. Identification of aberrant expression patterns and associated biological effects of ncRNAs in patients revealed their potential as novel biomarkers and therapeutic targets for cerebral infarction/ischemia-reperfusion injury. Therefore, this review systematically presents recent studies on the involvement of ncRNAs in cerebral infarction/ischemia-reperfusion injury and neuroimmune inflammatory cascades, and elucidates the functions and mechanisms of cerebral infarction/ischemia-reperfusion-related ncRNAs, providing new opportunities for the discovery of disease biomarkers and targeted therapy. Furthermore, this review introduces clustered regularly interspaced short palindromic repeats (CRISPR)-Display as a possible transformative tool for studying lncRNAs. In the future, ncRNA is expected to be used as a target for diagnosing cerebral infarction/ischemia-reperfusion injury, judging its prognosis and treatment, thereby significantly improving the prognosis of patients.

Abstract
INTRODUCTION Acute cerebral infarction (ACI) occurs with the involvement of differential expression of microRNAs. The study detected the expression pattern of miR-138-5p in the serum of ACI cases and evaluated its clinical significance, in an attempt to provide some guidance for the treatment and daily nursing of patients with ACI clinically. METHODS Levels of miR-138-5p in the serum of ACI patients and healthy controls (HCs) were detected via qRT-PCR. Ninety days after treatment, the modified Rankin Scale (mRS) was used to evaluate the prognosis of ACI patients. Receiver operating characteristic (ROC) curve was drawn, and the area under the curve was calculated. The logistic regression analysis was performed to estimate the relationship between various indicators and the clinical outcome. RESULTS miR-138-5p showed a diminished trend in ACI cases compared with the control group. A significantly negative correlation was detected for serum miR-138-5p with the National Institutes of Health Stroke Scale score in all ACI cases (r = -0.704, p < 0.001). The ROC curve demonstrated the diagnostic potential of serum miR-138-5p to distinguish ACI from HCs. Lessened expression of miR-138-5p was detected in ACI patients with poor prognosis, which can predict the poor prognosis of ACI patients after treatment. Logistic regression analysis determined the independent influence relationship between miR-138-5p and poor prognosis. CONCLUSION Diminished miR-138-5p is identified to be a risk factor for the occurrence of ACI, and it is associated with the worse outcome of the patients.

Abstract
Acute cerebral infarct (ACI) is a severe subtype of ischemic stroke. microRNAs (miRNAs) are implicated in the pathogenesis of ACI. This study investigated the expression pattern and clinical implication of miR-124 in ACI patients. Serum samples were collected from 108 healthy people and 108 ACI patients at 24 h, 48 h, and 72 h. Serum miR-124 expression was tested using qRT-PCR. The levels of interleukin (IL)-6, IL-8, and C-reactive protein (CRP) were detected using ELISA kits. The correlations between miR-124 expression and infarct classification, infarct size, risk factors, and inflammatory factors were analyzed. The diagnostic efficacy of miR-124 in ACI was analyzed by the ROC curve. ACI patients were assigned to the miR-124 high/low expression group and the incidence of poor prognosis was compared between the two groups. miR-124 expression was poorly expressed in the serum of ACI patients. The area under the ROC curve of miR-124 in the diagnosis of ACI was 0.9527, the specificity was 91.67%, and the sensitivity was 93.52%. miR-124 expression in ACI patients was not affected by infarct classification, infarct size, low-density lipoprotein level, and homocysteine level. miR-124 expression was negatively correlated with IL-6, IL-8, and CRP in ACI patients. Low expression of miR-124 was positively correlated with the poor prognosis of ACI. miR-124 was poorly expressed in the serum of ACI patients and served as a biomarker for the diagnosis and prognosis. This study shall confer a promising novel target for the diagnosis and treatment of ACI.

Abstract
Purpose Limited information exists on fall-related fractures in older adults with cerebrovascular disease. This study aimed to determine the characteristics of older adults with cerebrovascular disease who sustained fall-related fractures and identify the associated risk factors for perioperative complications. Patients and Methods This was a cross-sectional study, which included patients with cerebrovascular disease who sustained fractures between Jan. 2017 and Dec. 2019. The collected data included demographics (age and gender), time and place of fracture occurrence, mechanism of injury, fracture location, type of cerebrovascular disease, complications, and comorbidities. Results A total of 768 patients with 815 fractures were included; there were 253 males and 515 females, with an average age of 78.3 years. For either males or females, 80–84 years was the most commonly involved age group. Most (61.0%) patients had their fractures occurring at home and most fractures (70.7%) occurred during the daytime. Most were hip fractures and limb weakness; instability-related falls were the most common cause of fracture, making a proportion of 34.5%. Patients who suffered falls were mainly combining ischemic cerebrovascular disease. Most (85.9%) patients presented with at least one comorbid disease and the perioperative complication rate was 76.9% in total cases. Age≥80 (OR: 1.772, 95% CI: 1.236–2.540) and the number of comorbidities≥3 (OR: 1.606, 95% CI: 1.035–2.494) were found independently associated with complications, while the type of cerebrovascular disease, fracture location, and comorbidities of prior fragility fracture and respiratory disease were not significantly correlated with complications. Conclusion Our findings highlighted that more focus on improved physical function explored in intervention setting and the importance of primary home prevention measures seems justified in China and maybe other countries as well. It is the first study that presented the epidemiological characteristics of older adults with cerebrovascular disease who later experienced a fracture.

Abstract
The present study aimed to explore the expression and significance of S100 protein β (S100β), cystatin C (CysC), and nuclear factor kappa B (NF-κB) in patients with acute cerebral infarction (ACI). ACI patients (n=120) were selected as the experimental group at Xuzhou Central Hospital from August 2016 to August 2018. Ninety healthy subjects who underwent a physical examination at Xuzhou Central Hospital during the same period were selected as the control group. The expression levels of S-100β, CysC and NF-κB were compared between the two groups. Serum S-100β, CysC and NF-κB levels were compared between ACI patients with different degree of nervous functional defects, different infarct size and different prognosis. ROC curve analysis was used for the diagnosis of ACI by serum S-100β, CysC and NF-κB levels. Serum S-100β, CysC and NF-κB levels in the experimental group were higher than those in the control group (P<0.05). The levels of serum S-100β, CysC and NF-κB in patients with different neurological deficits were significantly different. The levels of serum S-100β, CysC and NF-κB in the severe and medium type infarction group were significantly higher than those in the mild type infarction group (both P<0.05). The levels of serum S-100β, CysC and NF-κB in the severe type infarction group were higher than those in the medium type infarction group (P<0.05). There were significant differences in serum S-100β, CysC and NF-κB levels in patients with different infarct sizes. The levels of serum S-100β, CysC and NF-κB in patients with large and medium size infarction were higher than those in the small size infarction group (both P<0.05). The levels of serum S-100β, CysC and NF-κB in patients with large size infarction were higher than those in patients with medium size infarction (P<0.05). Serum S-100β, CysC and NF-κB levels in patients of the worsening group were significantly higher than those in patients of the non-worsening group. The levels of S-100β, CysC, NF-κB in ACI patients were significantly higher than those in healthy subjects. Increased levels of S-100β, CysC and NF-κB can be used as ideal indexes for diagnosing cerebral infarction and studying the condition.

Abstract
Objective The aim of the present study is to explore the potential diagnostic and prognostic value of plasma levels of miR‐99 family for patients with acute cerebral infarction (ACI). Methods A total of 112 patients who have been diagnosed with ACI were enrolled in this study, and 112 healthy volunteers were served as the controls. The plasma of the patients and controls were collected, and total RNAs were isolated, and the expression levels of miR‐99a, miR‐99b, and miR‐100 in the plasma of patients and controls were compared determined by RT‐qPCR methods; moreover, the receiver operating characteristic (ROC) curve has been drawn to determine whether the plasma levels of miR‐99b can distinguish patients with ACI from the controls; furthermore, the short‐term prognosis of the patients was evaluated by glasgow outcome scale (GOS), and the correlation between the plasma levels of miR‐99b and the GOS of the patients was evaluated. Finally, the correlation between the plasma level of miR‐99 and VEGF of ACI patients was analyzed. Results It was observed that miR‐99b was significantly decreased in the plasma of ACI patients compared with the healthy controls (P < .01), while the plasma levels of miR‐99a and miR‐100 showed no significant differences between the patients with ACI and the healthy controls; moreover, the area under the curve (AUC) of miR‐99b for the diagnosis of ACI was 0.8882 (95% confidence interval (CI), 0.8451‐0.9313), suggesting that plasma level of miR‐99b is a sensitive marker to distinguish patients with ACI from the healthy volunteers; furthermore, the serum level of miR‐99b was negatively correlated with GOS score of the patients (r = −.56, P < .001); finally, the plasma level of miR‐99b was negatively correlated with the levels of VEGF (r = −.3013, P = .0012). Conclusion miR‐99b was down‐regulated in plasma of patients with ACI, and plasma level of miR‐99b may be a potential diagnostic and prognostic marker for the diagnosis and treatment of ACI.

Front Mol Neurosci 2018; 11:388. [PMID: 30483048 PMCID: PMC6243094 DOI: 10.3389/fnmol.2018.00388] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Accepted: 10/04/2018] [Indexed: 12/13/2022] Open
Abstract
Vascular dementia (VD) is the most common form of dementia in elderly people. However, little is understood about the role of microRNAs (miRNAs) involved in cognitive impairment in early VD. Here, a VD model induced by chronic cerebral ischemia and fetal bovine serum (FBS)-free cell model that detects synapse formation was established to investigate the function of miRNAs in early VD. The microarray analysis and real-time reverse transcription polymerase chain reaction (RT-PCR) showed that miR-210-5p increased significantly in the hippocampus of rats with 4 weeks of ischemia. The VD model rats also displayed significant cognitive deficits and synaptic loss. The overexpression of miR-210-5p decreased the synaptic number in primary hippocampal neurons, whereas specific suppression of miR-210-5p resulted in the formation of more synapses. Additionally, intracerebroventricular (ICV) injection of miR-210-5p agomir to VD rats aggravated phenotypes of cognitive impairment and synaptic loss. These VD-induced phenotypes were effectively attenuated by miR-210-5p antagomir. Moreover, bioinformatic prediction revealed that synaptosomal-associated protein of 25 KDa (Snap25) mRNA is targeted by miR-210-5p. The miR-210-5p decreased the luciferase activities of 3’ untranslated region (3’UTR) of Snap25 mRNA. Mutation of predicted miR-210-5p binding sites in the 3’ UTR of Snap25 mRNA abolished the miR-210-5p-induced decrease in luciferase activity. Western blot and immunofluorescence staining confirmed that miR-210-5p targets Snap25. Finally, RT-quantitative PCR (qPCR) and immunofluorescence staining detected that miR-210-5p agomir downregulated Snap25 expression in the cornu ammonis1 (CA1) region of hippocampi in VD rats, whereas miR-210-5p antagomir upregulated Snap25 expression. Altogether, miR-210-5p contributes to cognitive impairment in chronic ischemia-induced VD model through the regulation of Snap25 expression, which potentially provides an opportunity to develop a new therapeutic strategy for VD.
