Cardiovasc Toxicol 2024; 24:225-239. [PMID: 38324114 DOI: 10.1007/s12012-023-09824-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 12/26/2023] [Indexed: 02/08/2024]
Abstract
Aortic dissection (AD) is a severe vascular disease with high rates of mortality and morbidity. However, the underlying molecular mechanisms of AD remain unclear. Differentially expressed genes (DEGs) were screened by bioinformatics methods. Alterations of histopathology and inflammatory factor levels in β-aminopropionitrile (BAPN)-induced AD mouse model were evaluated through Hematoxylin-Eosin (HE) staining and Enzyme-linked immunosorbent assay (ELISA), respectively. Reverse transcription quantitative real-time polymerase chain reaction was performed to detect DEGs expression. Furthermore, the role of LILRB4 in AD was investigated through Cell Counting Kit-8 (CCK-8), wound healing, and flow cytometry. Western blotting was employed to assess the phenotypic switch and extracellular matrix (ECM)-associated protein expressions in platelet-derived growth factor-BB (PDGF-BB)-stimulated in vitro model of AD. In the AD mouse model, distinct dissection formation was observed. TNF-α, IL-1β, IL-8, and IL-6 levels were higher in the AD mouse model than in the controls. Six hub genes were identified, including LILRB4, TIMP1, CCR5, CCL7, MSR1, and CLEC4D, all of which were highly expressed. Further exploration revealed that LILRB4 knockdown inhibited the cell vitality and migration of PDGF-BB-induced HASMCs while promoting apoptosis and G0/G1 phase ratio. More importantly, LILRB4 knockdown promoted the protein expression of α-SMA and SM22α, while decreasing the expression of Co1, MMP2, and CTGF, which suggested that LILRB4 silencing promoted contractile phenotypic transition and ECM stability. LILRB4 knockdown inhibits the progression of AD. Our study provides a new potential target for the clinical treatment of AD.

Abstract
Meat quality is a critical aspect of pig breeding. In addition to genetics, meat quality is also influenced by nutritional and environmental factors. In this study, three pig breeds, Shengxianhua, Jiaxing, and Qinglian Black (SXH, JXB and QLB), were used as experimental animals. Transcriptional analysis was performed on the longissimus thoracis (LT) muscle to investigate variations in intramuscular fat (IMF), inosine monophosphate (IMP), amino acids, and muscle fiber morphology across different breeds. Ingenuity canonical pathway analysis (IPA) identified biological processes and key driver genes related to metabolism and muscle development. Additionally, weighted gene co-expression network analysis (WGCNA) revealed gene modules associated with IMP. KEGG and GO analyses identified specific biological processes and signaling pathways related to IMP, including the Oxidative Phosphorylation pathway and rRNA Metabolic Processes. These findings provide novel insights into the molecular regulatory mechanisms underlying meat quality variations among pig breeds.

Abstract
Aortic dissection (AD) has an unfavorable prognosis. It requires early diagnosis, appropriate treatment strategies, and suspicion to recognize symptoms; thus, it is commonly described as an acute aortic emergency. The clinical manifestations of painless AD are complex and variable. However, there is no effective treatment to prevent the progression of AD. Therefore, study of the molecular targets and mechanisms of AD to enable prevention or early intervention is particularly important. Although multiple gene mutations have been proposed as linked to AD development, evidence that multiple epigenetic elements are strongly associated is steadily increasing. These epigenetic processes include DNA methylation, N6-methyladenosine, histone modification, non-histone posttranslational modification, and non-coding RNAs (ncRNAs). Among these processes, resveratrol targeting Sirtuin 1 (SIRT1), 5-azacytidine (5azaC) targeting DNA methyltransferase (DNMT), and vitamin C targeting ten-eleven translocation 2 (Tet2) showed unique advantages in improving AD and vascular dysfunction. Finally, we explored potential epigenetic drugs and diagnostic methods for AD, which might provide options for the future.

ANNALS OF TRANSLATIONAL MEDICINE 2023; 11:350.

Abstract
Background Thoracic aortic dissection (TAD) is a very serious vascular condition that requires immediate treatment. Phenotypic conversion of human aortic smooth muscle cells (HASMCs) has been reported to be a causal factor for TAD development. Genetic variations affecting RNA modification may play a functional role in TAD. In this study, we aimed to explore the potential role of the methyltransferase like 3 (METTL3) and notch homolog 1 (NOTCH1) N6-methyladenosine (m6A) modification mechanisms in HASMCs. Methods HASMCs were cultured. METTL3 was knocked down and overexpressed. Then, both METTL3 and NOTCH1 were simultaneously knocked down in HASMCs. HASMC proliferation was determined using Cell Counting Kit-8 (CCK-8). METTL3, NOTCH1, α-smooth muscle actin (α-SMA), smooth muscle protein 22-alpha (SM22α), and calponin expressions were monitored with quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. An m6A dot blot assay was used to examine the m6A modification levels. The NOTCH1 3' untranslated region (3'UTR) m6A modification was analyzed using SRAMP and RMBase v. 2.0. A methylated RNA immunoprecipitation (MeRIP) assay was used to evaluate the METTL3 overexpression effect on m6A modification of NOTCH1 messenger RNA (mRNA). A dual-luciferase assay was used to investigate the effect of METTL3 binding of the NOTCH1 mRNA m6A modification site. YTH domain family 2 (YTHDF2)-RNA immunoprecipitation (RIP) was used to detect the change in YTHDF2's ability to bind to NOTCH1 mRNA after METTL3 overexpression. Results Overexpression of METTL3 inhibited α-SMA, SM22α, calponin, and NOTCH1 expressions and promoted HASMC proliferation. Knocking down METTL3 had the opposite effect. The cointerference of the METTL3 and NOTCH1 results suggested that METTL3 regulated NOTCH1, contributing to HASMC phenotypic changes. The MeRIP assay showed that the m6A modification of NOTCH1 mRNA increased after METTL3 overexpression. The dual-luciferase assay indicated that the NOTCH1 mRNA m6A modification site and METTL3 overexpression promoted NOTCH1 mRNA degradation. YTHDF2-RIP further demonstrated that the binding ability of YTHDF2 and NOTCH1 mRNA was enhanced after METTL3 overexpression. Conclusions METTL3 regulated the phenotypic changes of HASMC by upregulating m6A modification of NOTCH1 and inhibiting NOTCH1.

Abstract
OBJECTIVES To evaluate the potential effect of EphrinB2 in human thoracic aortic dissection (TAD) and to illustrate the mechanisms governing the role of EphrinB2 in the growth of human aortic smooth muscle cells (HASMC). METHODS In the study, EphrinB2 expression was investigated by qRT-PCR and immunohistochemistry in 12 pairs of TAD and adjacent human tissues. HASMCs were used for in vitro experiments. Next, EphrinB2 overexpression and depletion in HASMCs were established by EphrinB2-overexpressing vectors and small interfering RNA, respectively. The transfection efficiency was evaluated by qRT-PCR and Western blot. The effects of overexpression and depletion of EphrinB2 on cell proliferation, migration, and invasion were tested in vitro. Cell Counting Kit-8, flow cytometry and transwell migration/invasion, and wound healing assay were used to explore the function of EphrinB2 on HASMC cell lines. The relationship between EphrinB2 and F-actin was assessed by Western blot, immunofluorescence, and Co-IP. RESULTS We found that EphrinB2 was a prognostic biomarker of TAD patients. Moreover, EphrinB2 expression negatively correlated to aortic dissection tissues, and disease incidence of males, suggesting that EphrinB2 might act as a TAD suppressor by promoting proliferation or decreasing apoptosis in HASMC. Next, over-expression of EphrinB2 in HASMC lines drove cell proliferation, migration, and invasion, and inhibited apoptosis while knockdown EphrinB2 showed the opposite phenomenon, respectively. Furthermore, the level of F-actin in mRNA, protein, and distribution in HASMC cell lines highly matched with the expression of EphrinB2, which indicated that EphrinB2 could mediate the HASMC cytoskeleton via inducing F-actin. CONCLUSIONS In conclusion, our results first provided the pivotal role of EphrinB2 in HASMC proliferation initiated by mediating F-actin and demonstrated a prognostic biomarker and the potential targets for therapy to prevent thoracic aortic dissection.

Abstract
Aortic dissection (AD) is a fatal cardiovascular acute disease with high incidence and mortality, and it seriously threatens patients’ lives and health. The pathogenesis of AD mainly includes vascular inflammation, extracellular matrix degradation, and phenotypic conversion as well as apoptosis of vascular smooth muscle cells (VSMCs); however, its detailed mechanisms are still not fully elucidated. Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are an emerging class of RNA molecules without protein-coding ability, and they play crucial roles in the progression of many diseases, including AD. A growing number of studies have shown that the dysregulation of ncRNAs contributes to the occurrence and development of AD by modulating the expression of specific target genes or the activity of related proteins. In addition, some ncRNAs exhibit great potential as promising biomarkers and therapeutic targets in AD treatment. In this review, we systematically summarize the recent findings on the underlying mechanism of ncRNA involved in AD regulation and highlight their clinical application as biomarkers and therapeutic targets in AD treatment. The information reviewed here will be of great benefit to the development of ncRNA-based therapeutic strategies for AD patients.

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
BACKGROUND Aortic aneurysms (AA) are pathological dilations of the aorta, associated with an overall mortality rate up to 90% in case of rupture. In addition to dilation, the aortic layers can separate by a tear within the layers, defined as aortic dissections (AD). Vascular smooth muscle cells (vSMC) are the predominant cell type within the aortic wall and dysregulation of vSMC functions contributes to AA and AD development and progression. However, since the exact underlying mechanism is poorly understood, finding potential therapeutic targets for AA and AD is challenging and surgery remains the only treatment option. METHODS In this review, we summarize current knowledge about vSMC functions within the aortic wall and give an overview of how vSMC functions are altered in AA and AD pathogenesis, organized per anatomical location (abdominal or thoracic aorta). RESULTS Important functions of vSMC in healthy or diseased conditions are apoptosis, phenotypic switch, extracellular matrix regeneration and degradation, proliferation and contractility. Stressors within the aortic wall, including inflammatory cell infiltration and (epi)genetic changes, modulate vSMC functions and cause disturbance of processes within vSMC, such as changes in TGF-β signalling and regulatory RNA expression. CONCLUSION This review underscores a central role of vSMC dysfunction in abdominal and thoracic AA and AD development and progression. Further research focused on vSMC dysfunction in the aortic wall is necessary to find potential targets for noninvasive AA and AD treatment options.

Abstract
The osteogenic differentiation capacity of senescent bone marrow mesenchymal stem cells (MSCs) is reduced. p53 not only regulates cellular senescence but also functions as a negative regulator in bone formation. However, the role of p53 in MSCs senescence and differentiation has not been extensively explored. In the present study, we investigated the molecular mechanism of p53 in MSCs senescence and osteogenic differentiation. We found that p53 was upregulated during cellular senescence and osteogenic differentiation of MSCs respectively induced by H2O2 and BMP9. Similarly, the expression of p53-induced miR-145a was increased significantly. Furthermore, Overexpression of miR-145a in MSCs promoted cellular senescence and inhibited osteogenic differentiation. Then, we identified that p53-induced miR-145a inhibited osteogenic differentiation by targeting core binding factor beta (Cbfb), and the restoration of Cbfb expression rescued the inhibitory effects of miRNA-145a. In summary, our results indicate that p53/miR-145a axis exert its functions both in promoting senescence and inhibiting osteogenesis of MSCs, and the novel p53/miR-145a/Cbfb axis in osteogenic differentiation of MSCs may represent new targets in the treatment of osteoporosis.

Abstract
Aortic dissection (AD) is the rupture of the aortic intima, causing the blood in the cavity to enter the middle of the arterial wall. Without urgent and proper treatment, the mortality rate increases to 50% within 48 hours. Most patients present with acute onset of symptoms, including sudden severe pain and complex and variable clinical manifestations, which can be easily misdiagnosed. Despite this, the molecular mechanisms underlying AD are still unknown. Recently, non‐coding RNAs have emerged as novel regulators of gene expression. Previous studies have proven that ncRNAs can regulate several cardiovascular diseases; therefore, their potential as clinical biomarkers and novel therapeutic targets for AD has aroused widespread interest. To date, several studies have reported that microRNAs are crucially involved in AD progression. Additionally, several long non‐coding RNAs and circular RNAs have been found to be differentially expressed in AD samples, suggesting their potential roles in vascular physiology and disease. In this review, we discuss the functions of ncRNAs in AD pathophysiology and highlight their potential as biomarkers and therapeutic targets for AD. Meanwhile, we present the animal models previously used for AD research, as well as the specific methods for constructing mouse or rat AD models.

Aortic dissection (AD) is a fatal disease characterized by a ruptured intima that leads to the complete rupture of the aorta. The aim of this study is to examine the immunohistochemical expression of inflammation/fibrosis-associated chemical mediators in AD patients. Surgical specimens of aortic tissues were obtained from 37 patients who underwent an open thoracic aortic repair. AD was detected with histological staining. Local congestion and hemorrhage as well as chronic inflammatory cells infiltrations were observed at the dissection. Moreover, extensive disarrangement and disruption of elastic fibers were observed in the medial layer of the aorta with dissection. In summary, our study revealed that the apoptotic rate of vascular SMCs (VSMCs) in the vascular middle layer is higher in the dissected aortas than in the control aortas, suggesting that abnormally elevated apoptosis is correlated with AD pathogenesis. Functional studies of key genes identified in the apoptotic pathways as well as in extracellular matrix would be critical in thoroughly understanding the underlying mechanisms of AD development. Targeting the mediators related to TGF-β1, the Smad family proteins, and caspase 3 or anti-apoptotic agents may provide diagnostic markers and therapeutic targets that could be used to prevent AD.

Involvement of miR-145 in the development of aortic dissection via inducing proliferation, migration, and apoptosis of vascular smooth muscle cells. J Clin Lab Anal 2019; 34:e23028. [PMID: 31489719 PMCID: PMC6977357 DOI: 10.1002/jcla.23028] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 08/02/2019] [Accepted: 08/05/2019] [Indexed: 01/22/2023] Open
Abstract
Aim The current study aimed to examine miR‐145's contribution to thoracic aortic dissection (AD) development by modulating the biological functions of vascular smooth muscle cells (VSMCs). Methods The concentration of circulating miR‐145 was determined in patients with AD and healthy controls using quantitative polymerase chain reaction (qPCR). Aortic specimens were obtained from both individuals with Stanford type A AD undergoing surgical treatment and deceased organ donors (serving as controls) whose causes of death were nonvascular diseases. Then, qPCR and fluorescence in situ hybridization were applied to assess miR‐145 amounts and location, respectively. Furthermore, qPCR and immunoblot were employed to determine SMAD3 (the target gene of miR‐145, involved in the TGF‐β pathway) amounts at the gene and protein levels, respectively. Moreover, in vitro transfection of VSMCs with miR‐145 mimics or inhibitors was conducted. Finally, the 3‐(4,5‐Dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT) assay, Transwell assay and flow cytometry were employed for detecting VSMC proliferation, migration, and apoptosis, respectively. Results The amounts of miR‐145 in plasma and aortic specimens were markedly reduced in the AD group in comparison with control values (P < .05). miR‐145 was mostly located in VSMCs. Proliferation and apoptosis of VSMCs were significantly induced in vitro by the downregulation of miR‐145. Also, miR‐145 modulated SMAD3 expression. Conclusions miR‐145 was found to be downregulated in patients with AD, which induced the proliferation, migration, and apoptosis of VSMCs by targeting SMAD3. This suggested the involvement of miR‐145 in the pathogenesis of AD.
