Abstract
Vascular smooth muscle cell (vSMC) dysfunction is a critical contributor to cardiovascular diseases, including atherosclerosis, restenosis and vein graft failure. Recent advances have unveiled a fascinating range of non-coding RNAs (ncRNAs) that play a pivotal role in regulating vSMC function. This review aims to provide an in-depth analysis of the mechanisms underlying vSMC dysfunction and the therapeutic potential of various ncRNAs in mitigating this dysfunction, either preventing or reversing it. We explore the intricate interplay of microRNAs, long-non-coding RNAs and circular RNAs, shedding light on their roles in regulating key signalling pathways associated with vSMC dysfunction. We also discuss the prospects and challenges associated with developing ncRNA-based therapies for this prevalent type of cardiovascular pathology.

Liu S, Zhou H, Han D, Song H, Li Y, He S, Du Y, Wang K, Huang X, Li X, Huang Z. LncRNA CARMN inhibits abdominal aortic aneurysm formation and vascular smooth muscle cell phenotypic transformation by interacting with SRF. Cell Mol Life Sci 2024; 81:175. [PMID: 38597937 PMCID: PMC11006735 DOI: 10.1007/s00018-024-05193-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 02/29/2024] [Accepted: 03/01/2024] [Indexed: 04/11/2024]
Abstract
Phenotypic transformation of vascular smooth muscle cells (VSMCs) plays a crucial role in abdominal aortic aneurysm (AAA) formation. CARMN, a highly conserved, VSMC-enriched long noncoding RNA (lncRNA), is integral in orchestrating various vascular pathologies by modulating the phenotypic dynamics of VSMCs. The influence of CARMN on AAA formation, particularly its mechanisms, remains enigmatic. Our research, employing single-cell and bulk RNA sequencing, has uncovered a significant suppression of CARMN in AAA specimens, which correlates strongly with the contractile function of VSMCs. This reduced expression of CARMN was consistent in both 7- and 14-day porcine pancreatic elastase (PPE)-induced mouse models of AAA and in human clinical cases. Functional analyses disclosed that the diminution of CARMN exacerbated PPE-precipitated AAA formation, whereas its augmentation conferred protection against such formation. Mechanistically, we found CARMN's capacity to bind with SRF, thereby amplifying its role in driving the transcription of VSMC marker genes. In addition, our findings indicate an enhancement in CAMRN transcription, facilitated by the binding of NRF2 to its promoter region. Our study indicated that CARMN plays a protective role in preventing AAA formation and restrains the phenotypic transformation of VSMC through its interaction with SRF. Additionally, we observed that the expression of CARMN is augmented by NRF2 binding to its promoter region. These findings suggest the potential of CARMN as a viable therapeutic target in the treatment of AAA.

Cell Tissue Res 2023; 394:455-469. [PMID: 37907763 DOI: 10.1007/s00441-023-03836-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 10/02/2023] [Indexed: 11/02/2023]
Abstract
Excessive proliferation and migration of vascular smooth muscle cells (VSMCs) contribute to the intimal hyperplasia in type 2 diabetes mellitus (T2DM) patients after percutaneous coronary intervention. We aimed to investigate the role of lncRNA cyclin-dependent kinase inhibitor 2B antisense RNA 1 (CDKN2B-AS1) in VSMC proliferation and migration, as well as the underlying mechanism. T2DM model mice with carotid balloon injury were used in vivo and mouse aortic vascular smooth muscle cells (MOVAS) stimulated by insulin were used in vitro to assess the role of CDKN2B-AS1 in VSMC proliferation and migration following vascular injury in T2DM state. To investigate cell viability and migration, MTT assay and Transwell assay were conducted. To elucidate the underlying molecular mechanisms, the methylation-specific polymerase chain reaction, RNA immunoprecipitation, RNA-pull down, co-immunoprecipitation, and chromatin immunoprecipitation were performed. In vivo, CDKN2B-AS1 was up-regulated in common carotid artery tissues. In vitro, insulin treatment increased CDKN2B-AS1 level, enhanced MOVAS cell proliferation and migration, while the promoting effect was reversed by CDKN2B-AS1 knockdown. CDKN2B-AS1 forms a complex with enhancer of zeste homolog 2 (EZH2) and DNA methyltransferase (cytosine-5) 1 (DNMT1) to regulate smooth muscle 22 alpha (SM22α) methylation levels. In insulin-stimulated cells, SM22α knockdown abrogated the inhibitory effect of CDKN2B-AS1 knockdown on cell viability and migration. Injection of lentivirus-sh-CDKN2B-AS1 relieved intimal hyperplasia in T2DM mice with carotid balloon injury. Up-regulation of CDKN2B-AS1 induced by insulin promotes cell proliferation and migration by targeting SM22α through forming a complex with EZH2 and DNMT1, thereby aggravating the intimal hyperplasia after vascular injury in T2DM.

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
Long non-coding RNA (lncRNAs) are longer than 200 nucleotides and cannot encode proteins but can regulate the expression of genes through epigenetic, transcriptional, and post-transcriptional modifications. The pathophysiology of smooth muscle cells can lead to many vascular diseases, and studies have shown that lncRNAs can regulate the phenotypic conversion of smooth muscle cells so that smooth muscle cells proliferate, migrate, and undergo apoptosis, thereby affecting the development and prognosis of vascular diseases. This review discusses the molecular mechanisms of lncRNA as a signal, bait, stent, guide, and other functions to regulate the phenotypic conversion of vascular smooth muscle cells, and summarizes the role of lncRNAs in regulating vascular smooth muscle cells in atherosclerosis, hypertension, aortic dissection, vascular restenosis, and aneurysms, providing new ideas for the diagnosis and treatment of vascular diseases.

Abstract
Aortic dissection (AD) is a fatal cardiovascular disease. It is caused by a rupture of the aortic intima or bleeding of the aortic wall that leads to the separation of different aortic wall layers. Patients with untreated AD have a mortality rate of 1–2% per hour after symptom onset. Therefore, effective biomarkers and therapeutic targets are needed to reduce AD-associated mortality. With the development of molecular technology, researchers have begun to explore the pathogenesis of AD at gene and protein levels, and have made some progress, but the pathogenesis of AD remains unclear. Non-coding RNAs, such as microRNAs, lncRNAs, and circRNAs, have been identified as basic regulators of gene expression and are found to play a key role in the pathogenesis of AD. Thus, providing a theoretical basis for developing these non-coding RNAs as clinical biomarkers and new therapeutic targets for AD in the future. Previous studies on the pathogenesis of AD focused on miRNAs, but recently, there have been an increasing number of studies that explore the role of lncRNAs, and circRNAs in AD. This review summarizes the existing knowledge on the roles of various non-coding RNAs in the pathogenesis of AD, discusses their potential role as clinical biomarkers and therapeutic targets, states the limitations of existing evidence, and recommends future avenues of research on the pathogenesis of AD.

Abstract
OBJECTIVE The patterns of lncRNA CDKN2B-AS1 in coronary heart disease (CHD) have been extensively studied. This study investigated the competing endogenous RNA (ceRNA) network of CDKN2B-AS1 in coronary atherosclerosis (CAS). METHODS Microarray analyses were performed to screen out the CHD-related lncRNAs (CDKN2B-AS1) and the downstream microRNAs (miR-126-5p). The expression of CDKN2B-AS1 in serum of patients with CHD and healthy volunteers was detected. Vascular smooth muscle cells (VSMCs) were treated with oxidized low density lipoprotein (ox-LDL) to establish the cell model. Then pcDNA-CDKN2B-AS1 and/or miR-126-5p mimic were transfected into ox-LDL-treated VSMCs to estimate cell proliferation, apoptosis and inflammation. The ceRNA network of CDKN2B-AS1 along with the possible pathway in CHD was testified. RESULTS CDKN2B-AS1 expression was low in patients with CHD and ox-LDL-treated VSMCs. Upon CDKN2B-AS1 overexpression, TNF-α, NF-κB and IL-1β levels in VSMCs were decreased, the proliferation of VSMCs was inhibited and the apoptosis rate was increased. Overexpression of miR-126-5p could reverse these trends. CDKN2B-AS1 as a ceRNA competitively bound to miR-126-5p to upregulate PTPN7. CDKN2B-AS1 inhibited VSMC proliferation and accelerated apoptosis by inhibiting the PI3K-Akt pathway. CONCLUSION LncRNA CDKN2B-AS1 upregulates PTPN7 by absorbing miR-126-5p and inhibits the PI3K-Akt pathway, thus hindering the proliferation and accelerating apoptosis of VSMCs induced by ox-LDL, thus being a therapeutic approach for CAS.
