Integrative bioinformatics analysis of miRNA and mRNA expression profiles and identification of associated miRNA-mRNA network in intracranial aneurysms. Noncoding RNA Res 2024; 9:471-485. [PMID: 38511055 PMCID: PMC10950608 DOI: 10.1016/j.ncrna.2024.01.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 01/08/2024] [Accepted: 01/08/2024] [Indexed: 03/22/2024] Open
Abstract
Background Intracranial aneurysms (IAs) represent protrusions in the vascular wall, with their growth and wall thinning influenced by various factors. These processes can culminate in the rupture of the aneurysm, leading to subarachnoid hemorrhage (SAH). Unfortunately, over half of the patients prove unable to withstand SAH, succumbing to adverse outcomes despite intensive therapeutic interventions, even in premier medical facilities. This study seeks to discern the pivotal microRNAs (miRNAs) and genes associated with the formation and progression of IAs. Methods The investigation gathered expression data of miRNAs (from GSE66240) and mRNAs (from GSE158558) within human aneurysm tissue and superficial temporal artery (STA) samples, categorizing them into IA and normal groups. This classification was based on the Gene Expression Omnibus (GEO) database. Results A total of 70 differentially expressed microRNAs (DEMs) and 815 differentially expressed mRNAs (DEGs) were pinpointed concerning IA. Subsequently, a miRNA-mRNA network was constructed, incorporating 9 significantly upregulated DEMs and 211 significantly downregulated DEGs. Simultaneously, functional enrichment and pathway analyses were conducted on both DEMs and DEGs. Through protein-protein interaction (PPI) network analysis and functional enrichment, 9 significantly upregulated DEMs (hsa-miR-188-5p, hsa-miR-590-5p, hsa-miR-320b, hsa-miR-423-5p, hsa-miR-140-5p, hsa-miR-486-5p, hsa-miR-320a, hsa-miR-342-3p, and hsa-miR-532-5p) and 50 key genes (such as ATP6V1G1, KBTBD6, VIM, PA2G4, DYNLL1, METTL21A, MDH2, etc.) were identified, suggesting their potential significant role in IA. Among these genes, ten were notably negatively regulated by at least two key miRNAs. Conclusions The findings of this study provide valuable insights into the potential pathogenic mechanisms underlying IA by elucidating a miRNA-mRNA network. This comprehensive approach sheds light on the intricate interplay between miRNAs and genes, offering a deeper understanding of the molecular dynamics involved in IA development and progression.

Abstract
BACKGROUND Aberrant expression of circular RNA (circRNA) has been demonstrated to be related to atherosclerosis (AS) formation. However, the mechanism of circCHMP5 (also known as hsa_circ_0003575) in AS formation remains unclear. METHODS Oxidized low-density lipoprotein (ox-LDL) was used to treat human umbilical vein endothelial cells (HUVECs) to construct a cell injury model. The expression level of circCHMP5, miR-532-5p, and Rho-associated protein kinase 2 (ROCK2) was measured using quantitative real-time PCR. Cell cycle, apoptosis, proliferation, and angiogenesis were determined by flow cytometry, 5-ethynyl-2'-deoxyuridine (EdU) assay, and tube formation assay. In addition, the protein expression of apoptosis markers, inflammation factors, and ROCK2 was detected by western blot analysis. The interaction between miR-532-5p and circCHMP5 or ROCK2 was assessed by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. RESULTS Our results indicated that circCHMP5 was overexpressed in ox-LDL-induced HUVECs. CircCHMP5 knockdown promoted cell cycle, proliferation, and angiogenesis while inhibiting apoptosis and inflammation in ox-LDL-induced HUVECs. MiR-532-5p could be sponged by circCHMP5, and its inhibitor reversed the negative regulation of si-circCHMP5 on ox-LDL-induced HUVECs injury. ROCK2, a target of miR-532-5p, reversed the inhibition effect of miR-532-5p on ox-LDL-induced HUVECs injury. Furthermore, we confirmed that circCHMP5 upregulated ROCK2 by sponging miR-532-5p. CONCLUSION To sum up, our data showed that circCHMP5 regulated the miR-532-5p/ROCK2 axis to accelerate ox-LDL-induced HUVECs injury, confirming that circCHMP5 might be a potential target for AS treatment.

Abstract
Mitochondrial dysfunction is a recognized factor in the pathogenesis of deep vein thrombosis (DVT). The role of 7S RNA, a long noncoding RNA that plays an important role in mitochondrial function, in DVT remains unclear. In this study, we aimed to investigate the potential use of 7S RNA as a biomarker in DVT. Plasma samples were obtained from 237 patients (aged 16-95 years) with suspected DVT recruited in a prospective multicenter management study (SCORE) where 53 patients were objectively confirmed with a diagnosis of DVT and the rest were diagnosed as non-DVT. 7S RNA was measured using quantitative real-time polymerase chain reaction in plasma samples. The plasma expression of 7S RNA was significantly lower in DVT compared with non-DVT (0.50 vs. 0.95, p = 0.043). With the linear regression analysis, we showed that the association between the plasma expression of 7S RNA and DVT (β = -0.72, p = 0.007) was independent of potential confounders. Receiver-operating characteristic curve analysis showed the area under the curve values of 0.60 for 7S RNA. The findings of the present study showed a notable association between 7S RNA and DVT. However, further investigations are needed to fully elucidate the exact role of 7S RNA in the pathophysiology of DVT and its diagnostic value.

Blood-based circulating microRNAs as diagnostic biomarkers for subclinical carotid atherosclerosis: A systematic review and meta-analysis with bioinformatics analysis. Diabetes Metab Syndr 2023; 17:102860.

Abstract
BACKGROUND Atherosclerosis in carotid arteries can remain clinically undetected in its early development until an acute cerebrovascular event such as stroke emerges. Recently, microRNAs (miRNAs) circulating in blood have emerged as potential diagnostic biomarkers, but their performance in detecting subclinical carotid atherosclerosis has yet to be systematically researched. AIM To investigate the diagnostic performance of circulating miRNAs in detecting subclinical carotid atherosclerosis. METHODS We systematically searched five electronic databases from inception to July 23, 2022. Subclinical carotid atherosclerosis was defined using carotid intima-media thickness (CIMT). Diagnostic accuracy parameters and correlation coefficients were pooled. A gene network visualisation and enrichment bioinformatics analysis were additionally conducted to search for potential target genes and pathway regulations of the miRNAs. RESULTS Fifteen studies (15 unique miRNAs) comprising 2542 subjects were identified. Circulating miRNAs had a pooled sensitivity of 85% (95% CI 80%-89%), specificity of 84% (95% CI 78%-88%), positive likelihood ratio of 5.19 (95% CI 3.97-6.80), negative likelihood ratio of 0.18 (95% CI 0.13-0.23), diagnostic odds ratio of 29.48 (95% CI 21.15-41.11), and area under the summary receiver operating characteristic curve of 0.91 (95% CI 0.88-0.93), with a strong correlation to CIMT (pooled coefficient 0.701; 95% CI 0.664-0.731). Bioinformatics analysis revealed a major role of the miRNAs, as shown by their relation with CCND1, KCTD15, SPARC, WWTR1, VEGFA genes, and multiple pathways involved in the pathogenesis of carotid atherosclerosis. CONCLUSION Circulating miRNAs had excellent accuracy in detecting subclinical carotid atherosclerosis, suggesting their utilisation as novel diagnostic tools.

Abstract
Background Atherosclerosis (AS) is closely related to stroke and cardiovascular diseases. Nuclear factor kappa-B (NF-κB) is the master regulator of inflammation, and thus, modulating the transcription of NF-κB can improve AS. Methods In this study, we conducted a bibliometric analysis to identify the frontiers, hotspots, and features of global research output on NF-κB in AS from 2000 to 2021. Papers published from 2000 to 2021 and the recorded information were retrieved from the Science Citation Index-Expanded of the Web of Science Core Collection. Bibliometric analysis and visualization were performed using VOSviewer and CiteSpace, including an analysis of the general distribution of annual output, highly productive countries, active journals, active institutions and authors, keywords, and co-cited references. Results A total of 5,439 original articles and reviews were retrieved and analyzed, and the results indicated that the annual number of publications on NF-κB in AS has been increasing in waves over the past 22 years. The majority of papers were published in China, while the USA had the highest number of citations and H-index. The most productive affiliation and journal were the University of California System and Arteriosclerosis Thrombosis and Vascular Biology, respectively. The papers of Chiu JJ. received the highest number of citations globally in 2011. The keywords, "nlrp3 inflammasome" and "microRNA", have recently attracted considerable attention, and very frequently occurring keywords included "NF kappa B", "atherosclerosis", "expression", "activation", "endogenous cell", and "oxidative stress". New keywords in 2021 included "muscle", "attenuates atherosclerosis", "mesenchymal transition", "metabolic disorder", and "palmitic acid". Conclusions AS and inflammation have become research hotspots lately. Over the past decade, most studies have focused on basic research, and pathways associated with the regulatory role of NF-κB in AS have become a particular focus in recent studies. Moreover, our study revealed that NF-κB plays a remarkable role in AS and may be a therapeutic target.

Abstract
MicroRNAs (miRNAs) are evolutionary conserved small noncoding RNA molecules with a significant ability to regulate gene expression at the posttranscriptional level either through translation repression or messenger RNA degradation. miRNAs are differentially expressed in various pathophysiological conditions, affecting the course of the disease by modulating several critical target genes. As the persistence of irreversible molecular changes caused by cigarette smoking is central to the pathogenesis of various chronic diseases, several studies have shown its direct correlation with the dysregulation of different miRNAs, affecting numerous essential biological processes. This review provides an insight into the current status of smoking-induced miRNAs dysregulation in chronic diseases such as COPD, atherosclerosis, pulmonary hypertension, and different cancers and explores the diagnostic/prognostic potential of miRNA-based biomarkers and their efficacy as therapeutic targets.

Abstract
Accumulating evidence pinpoints sex differences in stroke incidence, etiology and outcome. Therefore, more understanding of the sex-specific mechanisms that lead to ischemic stroke and aggravation of secondary damage after stroke is needed. Our current mechanistic understanding of cerebral ischemia states that endothelial quiescence in neurovascular units (NVUs) is a major physiological parameter affecting the cellular response to neuron, astrocyte and vascular smooth muscle cell (VSMC) injury. Although a hallmark of the response to injury in these cells is transcriptional activation, noncoding RNAs such as microRNAs exhibit cell-type and context dependent regulation of gene expression at the post-transcriptional level. This review assesses whether sex-specific microRNA expression (either derived from X-chromosome loci following incomplete X-chromosome inactivation or regulated by estrogen in their biogenesis) in these cells controls NVU quiescence, and as such, could differentiate stroke pathophysiology in women compared to men. Their adverse expression was found to decrease tight junction affinity in endothelial cells and activate VSMC proliferation, while their regulation of paracrine astrocyte signaling was shown to neutralize sex-specific apoptotic pathways in neurons. As such, these microRNAs have cell type-specific functions in astrocytes and vascular cells which act on one another, thereby affecting the cell viability of neurons. Furthermore, these microRNAs display actual and potential clinical implications as diagnostic and prognostic biomarkers in ischemic stroke and in predicting therapeutic response to antiplatelet therapy. In conclusion, this review improves the current mechanistic understanding of the molecular mechanisms leading to ischemic stroke in women and highlights the clinical promise of sex-specific microRNAs as novel diagnostic biomarkers for (silent) ischemic stroke.

Abstract
BACKGROUND miRNAs are involved in plaque formation of atherosclerosis and vessel restenosis. In this study, we investigated the effects of miR-599, miR-204, and miR-181b on VSMC proliferation, and migration through TGFβ receptor 2 (TGFβR2), β-arrestin 2 (β-ARR2), SMAD2/p-SMAD2, and ERK1/2/p-ERK1/2. MATERIALS & METHODS Genes and miRNAs were predicted by bioinformatics tools and were transfected by PEI-miRNAs (miR-599, miR-204, and miR-181b) complexes into VSMCs. The gene and protein expression levels were evaluated by real-time RT-PCR and western blotting techniques, respectively. The VSMC proliferation and migration were studied by MTT and scratch assay, respectively. RESULTS The miR-181b and miR-204 downregulated significantly β-ARR2 gene and protein expression levels and p-ERK1/2 values. Moreover, TGFβR2 gene and protein expression levels and p-SMAD2 values were not significantly affected by miR-181b and miR-204. The VSMC proliferation (p = 0.0019, p = 0.0054, respectively) and migration (p < 0.0001, p < 0.0001, respectively) were inhibited by the miR-181b and miR-204. The miR-599 inhibited VSMC proliferation (p = 0.044) and migration (p = 0.0055) but it did not affect significantly the β-ARR2 and TGFβR2 gene and protein expression levels. CONCLUSION The results suggested that the inhibitory effects of miR-181b and miR-204 on VSMC proliferation and migration are mediated by the β-ARR2/p-ERK1/2 pathway. Since VSMC proliferation and migration are involved in plaque growth, therefore this pathway can be a therapeutic target for atherosclerosis.

LncRNA BANCR induced vascular smooth muscle cell proliferation by downregulating miR-34c methylation in atherosclerosis. J Thromb Thrombolysis 2020; 51:924-932.

Abstract
Aberrant vascular smooth muscle cell (VSMCs) proliferation involves in the development of atherosclerosis. It reported that Long noncoding BRAF-activated noncoding RNA (BANCR) and miR-34c played opposite roles in the regulation of the proliferation of VSMCs, indicating that there might be a potential interaction between them. This study was to investigate the relationship between BANCR and miR-34c in atherosclerosis. Blood (5 ml) was obtained from 56 patients with atherosclerosis and 56 healthy volunteers after they were fasted overnight, and plasma was extracted from the blood. Human Aortic Smooth Muscle Cells (HASMCs) were used to perform in vitro cell experiments. RT-qPCR was performed to measure the expression of BANCR and miR-34c in plasma and HASMCs. Dual luciferase reporter assay detected the interaction between BANCR and miR-34c. CCK-8 assay was used to assess the effects of BANCR and miR-34c overexpression on the proliferation of HASMCs. Western blotting was used to assess the effects of BANCR and miR-34c overexpression on the protein expression of HMGB1, TNF-ɑ and Bcl-2. In this study, we found that BANCR was upregulated, while miR-34c was downregulated in atherosclerosis. Bioinformatics analysis showed that BANCR and miR-34c could directly interact with each other. Moreover, overexpression of BANCR could decrease the expression of miR-34c in HASMCs, but overexpression of miR-34c could not affect the expression of BANCR. Furthermore, overexpression of BACNR increased miR-34c methylation, and knockdown of endogenous BANCR decreased miR-34c methylation. In addition, overexpression of BANCR reduced the effects of miR-34c on HASMCs proliferation and reversed the effects of miR-34c on HMGB1, TNF-ɑ and Bcl-2 expression. BANCR overexpression could induce HASMCs proliferation by downregulating the miR-34c methylation. Therefore given BANCR upregulation in atherosclerosis, its expression may be considered as a novel and useful biomarker for atherosclerosis prevention and prognosis. However considering the possible effects of other underlying diseases on both BANCR expression and miR-34c in atherosclerosis, further investigation is suggested for future research.
