Abstract
The effect of oxidised lipoproteins on the endothelium, monocytes, platelets, and macrophages is a key factor in the initiation and development of atherosclerosis. Antioxidant action, lipoprotein metabolism, and chronic inflammation are the fields of research interest for better understanding the development of the disease. All the fields are related to inflammation and hence to the secretion of cytokines, which are being investigated as potential diagnostic markers for the onset of atherosclerosis. Pathways of vascular damage are crucial for the development of new laboratory readouts. The very early detection of endothelial cell damage associated with the onset of atherosclerosis, allowing the initiation of therapy, remains a major research goal. This article summarises the latest results on the relationship of tumour growth factor beta (TGF-β) isoforms and growth differentiation factor 15 (GDF-15) to the pathogenesis of atherosclerosis: which cells involved in atherosclerosis produce them, which effectors stimulate their synthesis and secretion, how they influence atherosclerosis development, and the relationship between the levels of TGF-β and GDF-15 in the blood and the development and extent of atherosclerosis.

Wu F, Bu S, Wang H. Role of TRP Channels in Metabolism-Related Diseases. Int J Mol Sci 2024; 25:692.

Abstract
Metabolic syndrome (MetS), with its high prevalence and significant impact on cardiovascular disease, poses a substantial threat to human health. The early identification of pathological abnormalities related to MetS and prevention of the risk of associated diseases is of paramount importance. Transient Receptor Potential (TRP) channels, a type of nonselective cation channel, are expressed in a variety of tissues and have been implicated in the onset and progression of numerous metabolism-related diseases. This study aims to review and discuss the expression and function of TRP channels in metabolism-related tissues and blood vessels, and to elucidate the interactions and mechanisms between TRP channels and metabolism-related diseases. A comprehensive literature search was conducted using keywords such as TRP channels, metabolic syndrome, pancreas, liver, oxidative stress, diabetes, hypertension, and atherosclerosis across various academic databases including PubMed, Google Scholar, Elsevier, Web of Science, and CNKI. Our review of the current research suggests that TRP channels may be involved in the development of metabolism-related diseases by regulating insulin secretion and release, lipid metabolism, vascular functional activity, oxidative stress, and inflammatory response. TRP channels, as nonselective cation channels, play pivotal roles in sensing various intra- and extracellular stimuli and regulating ion homeostasis by osmosis. They present potential new targets for the diagnosis or treatment of metabolism-related diseases.

Abstract
Vascular calcification (VC), an actively regulated process, has been recognized as an independent and strong predictor of cardiovascular disease (CVD) and mortality worldwide. Diet has been shown to have a major role in the progression of VC. Oxidative stress (OS), a common pro-calcification factor, is closely related to VC, and evidence strongly suggests that dietary antioxidants directly prevent VC. Herein, we provided an overview of OS and its key role in VC and underlined the mechanisms of harmful effects of OS on VC. Furthermore, we introduced dietary antioxidants, and discussed about surrounding the challenges of dietary antioxidants in VC management. This review will benefit future research about the effects of dietary antioxidants on cardiovascular health.

Abstract
Noncoding RNAs (ncRNAs) play fundamental roles in cardiac development and cardiovascular diseases (CVDs), which are a major cause of morbidity and mortality. With advances in RNA sequencing technology, the focus of recent research has transitioned from studies of specific candidates to whole transcriptome analyses. Thanks to these types of studies, new ncRNAs have been identified for their implication in cardiac development and CVDs. In this review, we briefly describe the classification of ncRNAs into microRNAs, long ncRNAs, and circular RNAs. We then discuss their critical roles in cardiac development and CVDs by citing the most up-to-date research articles. More specifically, we summarize the roles of ncRNAs in the formation of the heart tube and cardiac morphogenesis, cardiac mesoderm specification, and embryonic cardiomyocytes and cardiac progenitor cells. We also highlight ncRNAs that have recently emerged as key regulators in CVDs by focusing on six of them. We believe that this review concisely addresses perhaps not all but certainly the major aspects of current progress in ncRNA research in cardiac development and CVDs. Thus, this review would be beneficial for readers to obtain a recent picture of key ncRNAs and their mechanisms of action in cardiac development and CVDs.

Biochem Biophys Res Commun 2022; 630:133-142. [PMID: 36155059 DOI: 10.1016/j.bbrc.2022.08.065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 08/22/2022] [Accepted: 08/22/2022] [Indexed: 11/27/2022]
Abstract
The phenotypic transformation of vascular smooth muscle cells (VSMCs) plays a key role in the pathological process of atherosclerosis (AS), and TRPM7 is involved in this process. In this study, we verified whether circRNAs participate in the phenotypic transformation of VSMCs by regulating TRPM7 in AS. The RNA-sequencing data of atherosclerosis were downloaded and analysed from the GEO database. Only hsa_circ_0021155 related to TRPM7 was differentially expressed in AS. circRNA distribution and expression were observed via FISH and PCR. CCK8, scratch test and Transwell assay were used to observe the proliferation and migration of cells. Western blot was performed to examine changes in α-actin, calponin, SMMHC and TRPM7 proteins. The expression of hsa_circ_0021155 against has-miR-4459/miR-3689c was verified via PCR. The ceRNA relationship of TPRM7-miR4459-circ0021155 was verified via dual luciferase assay, and the effects of miR4459 mimic/inhibitor on the proliferation of cells were further observed. The expression of hsa_circ_0021155 and OX-LDL was increased in VSMCs. hsa_circ_0021155 promoted the expression of TRPM7 and inhibited the protein expression of α-actin, calponin and SMMHC. In addition, it promoted the proliferation and migration of cells and inhibited the expression of miR-3689c and miR-4459 but did not affect miR-4756-5p. The dual luciferase assay showed that circ0021155-miR4459-TRPM7 mRNA was highly compatible and could be mutually regulated by a ceRNA network. In conclusion, hsa_circ_0021155 regulates the proliferation, migration and phenotype transformation of VSMCs induced by OX-LDL via the miR-4459/TRPM7 axis. hsa_circ_0021155 and TRPM7 may offer novel therapeutic targets for atherosclerosis.

Abstract
Mechanical forces are critical physical cues that can affect numerous cellular processes regulating the development, tissue maintenance, and functionality of cells. The contribution of mechanical forces is especially crucial in the vascular system where it is required for embryogenesis and for maintenance of physiological function in vascular cells including aortic endothelial cells, resident macrophages, and smooth muscle cells. Emerging evidence has also identified a role of these mechanical cues in pathological conditions of the vascular system such as atherosclerosis and associated diseases like hypertension. Of the different mechanotransducers, mechanosensitive ion channels/receptors are gaining prominence due to their involvement in numerous physiological and pathological conditions. However, only a handful of potential mechanosensory ion channels/receptors have been shown to be involved in atherosclerosis, and their precise role in disease development and progression remains poorly understood. Here, we provide a comprehensive account of recent studies investigating the role of mechanosensitive ion channels/receptors in atherosclerosis. We discuss the different groups of mechanosensitive proteins and their specific roles in inflammation, endothelial dysfunction, macrophage foam cell formation, and lesion development, which are crucial for the development and progression of atherosclerosis. Results of the studies discussed here will help in developing an understanding of the current state of mechanobiology in vascular diseases, specifically in atherosclerosis, which may be important for the development of innovative and targeted therapeutics for this disease.

Downregulation of lncRNA SNHG16 inhibits vascular smooth muscle cell proliferation and migration in cerebral atherosclerosis by targeting the miR-30c-5p/SDC2 axis. Heart Vessels 2022; 37:1085-1096.

Abstract
Atherosclerosis (AS) is the basic lesion underlying the occurrence and development of cerebrovascular diseases. Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays a crucial role in AS. We aimed to explore the role of SNHG16 in AS and the molecular mechanism of VSMC involvement in the regulation of AS. The expression levels of SNHG16, miR-30c-5p and SDC2 were detected by qRT-PCR. CCK-8, wound healing and Transwell assays were used to assess ox-LDL-induced VSMC proliferation, migration, and invasion, respectively. Western blot analysis was used to detect SDC2 and MEK/ERK pathway-related protein levels. A dual-luciferase reporter assay confirmed the binding of SNHG16 with miR-30c-5p and miR-30c-5p with SDC2. SNHG16 and SDC2 expression was upregulated in patients with AS and ox-LDL-induced VSMCs, while miR-30c-5p was downregulated. Ox-LDL-induced VSMC proliferation and migration were increased, and the MEK/ERK signalling pathway was activated. MiR-30c-5p was targeted to SNHG16 and SDC2. Downregulating SNHG16 or upregulating miR-30c-5p inhibited ox-LDL-induced VSMC proliferation and migration and inhibited MEK/ERK signalling pathway activation. In contrast, downregulating miR-30c-5p or upregulating SDC2 reversed the effects of downregulating SNHG16 or upregulating miR-30c-5p. Furthermore, downregulating SDC2 inhibited ox-LDL-induced proliferation and migration of VSMCs and inhibited activation of the MEK/ERK signalling pathway, while upregulating lncRNA SNHG16 reversed the effects of downregulating SDC2. Downregulation of SNHG16 inhibited VSMC proliferation and migration in AS by targeting the miR-30c-5p/SDC2 axis. This study provides a possible therapeutic approach to AS.

[PMID: 34847450 DOI: 10.1016/j.atherosclerosis.2021.11.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 10/27/2021] [Accepted: 11/04/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND AIMS Human vascular smooth muscle cells (HA-VSMCs) are an important cell type involved in atherosclerosis. Low density lipoprotein (LDL) is a lipoprotein particle that carries cholesterol into peripheral tissue cells, and oxidized modified LDL (ox-LDL) is a well-known inducer of the atherosclerosis-related phenotype switch in VSMCs, leading to the occurrence of atherosclerosis. Accumulating studies have revealed that long non-coding RNAs (lncRNAs) mediate the effect of ox-LDL on the atherosclerosis-related biological activities of HA-VSMCs, including proliferation, migration, and apoptosis. However, the mechanism of small nucleolar RNA host gene 12 (SNHG12) in ox-LDL-induced phenotype switch of VSMCs remains unclear. Thus, this research dug in whether SNHG12 mediated the influence of ox-LDL on HA-VSMCs and the potential mechanism. METHODS Fundamental experiments and functional assays were performed to measure the function of SNHG12 on HA-VSMCs. Then, mechanism assays and rescue assays were performed to study the regulatory mechanism of SNHG12 in HA-VSMCs. RESULTS SNHG12 reversed the influence of ox-LDL treatment in enhancing cell proliferative and migratory abilities and weakening apoptotic ability in HA-VSMCs. SNHG12 was a competitive endogenous RNA (ceRNA) competing with sprouty RTK signaling antagonist 2 (SPRY2) to bind to miR-1301-3p, thus up-regulating SPRY2 expression in ox-LDL-treated HA-VSMCs. Besides, SNHG12 recruited serine and arginine rich splicing factor 1 (SRSF1) to stabilize negative regulator of ubiquitin like proteins 1 (NUB1) expression. CONCLUSIONS This study illustrated that SNHG12 inhibited cell proliferation, migration and facilitated cell apoptosis in ox-LDL-induced HA-VSMCs by up-regulating SPRY2 and NUB1.

Abstract
Atherosclerosis (AS) is a chronic inflammatory disease, the main causes of which include abnormal lipid metabolism, endothelial injury, physical and chemical injury, hemodynamic injury, genetic factors and so on. These causes can lead to inflammatory injury of blood vessels and local dysfunction. Bunao-Fuyuan decoction (BNFY) is a traditional Chinese medicine compound that can treat cardiovascular and cerebrovascular diseases, but its effect on AS is still unknown. The aim of this study was to investigate the effect and mechanism of BNFY in proliferation and migration of vascular smooth muscle cells (VSMCs) on AS. At first, the expression of α-SMA protein in ox-LDL-induced VSMCs, which was detected by immunofluorescence staining and western blot. CCK-8 technique and cloning technique were used to detect the cell proliferation of ox-LDL-induced VSMCs after adding BNFY. Meanwhile, the expression of proliferating protein Ki67 was detected by immunofluorescence staining. Western blot was also used to detect the expression of proliferation-related proteins CDK2, CyclinE1 and P27. Flow cytometry was used to detect the effect of BNFY on cell cycle. The effects of BNFY on proliferation and migration of cells were detected by cell scratch test and Transwell. Western blot was used to detect the expression of adhesion factors ICAM1, VCAM1, muc1, VE-cadherin and RHOA/ROCK-related proteins in cells. We found that the expression of AS marker α-SMA protein increased significantly and cells shriveled and a few floated on the medium after induction of ox-LDL on VSCMs. The proliferation rate of ox-LDL VSMCs decreased significantly after adding different doses of BNFY, and BNFY can inhibit cell cycle. Meanwhile, we also found that cell invasion and migration rate were significantly inhibited and related cell adhesion factors ICAM1, VCAM1, muc1 and VE-cadherin were inhibited too by BNFY. Finally, we found that BNFY inhibited the expression of RHOA, ROCK1, ROCK2, p-MLC proteins in the RHOA/ROCK signaling pathway. Therefore, we can summarize that BNFY may inhibit the proliferation and migration of atherosclerotic vascular smooth muscle cells by inhibiting the activity of RHOA/ROCK signaling pathway.

Abstract
Vascular smooth muscle cells (VSMCs) play a significant role in atherosclerosis. As a multifunctional protein, nucleolin (NCL) is involved in many important physiological and pathological processes. In this study, we aimed to investigate the role of nucleolin in VSMCs proliferation and cell cycle. The expression of nucleolin increased in VSMCs of mice with aortas advanced plaques. With the left common carotid-artery ligation-injury model, immunofluorescence staining revealed that nucleolin and Ki67 expression increased in VSMCs in mice left carotid artery compared with right carotid artery after surgery. POVPC or ox-LDL up-regulated nucleolin mRNA and protein expression in a dose- and time-dependent manner in HAVSMCs. POVPC (5μg/ml) or ox-LDL (50μg/ml) promoted the proliferation of HAVSMCs. Nucleolin ablation relieved the pro-proliferation role of VSMCs. The cell cycle assay and cell ability results showing that POVPC or ox-LDL increased the proliferation, but nucleolin ablation inhibited the proliferation of HAVSMCs. And nucleolin ablation can prevent DNA replication at S phase and induce cell cycle arrest in S phase. The bioinformatics database predicts protein-protein interactions with nucleolin and aurora B. Nucleolin overexpression and ablation affected the expression of aurora B. These findings indicate for the first time that nucleolin actively involved the proliferation of VSMCs via aurora B.

Abstract
AIMS Circular RNAs (circRNAs) are relevant to atherosclerosis progression. However, the role and mechanism of circRNA hsa_circ_0029589 (circ_0029589) in atherosclerosis are not fully understood. This research aims to explore the function and mechanism of circ_0029589 in oxidized low-density lipoprotein (ox-LDL)-caused vascular smooth muscle cells (VSMCs) injury in vitro. MAIN METHODS VSMCs were challenged via ox-LDL to mimic atherosclerosis-like injury in vitro. Circ_0029589, microRNA-214-3p (miR-214-3p) and stromal interaction molecule 1 (STIM1) abundances were detected via quantitative reverse transcription polymerase chain reaction or western blot. Cell proliferation was investigated via cell viability, cycle, apoptosis and proliferation-associated protein levels. Cell migration and invasion were assessed via transwell analysis. The relationship between miR-214-3p and circ_0029589 or STIM1 was tested via dual-luciferase reporter analysis and RNA immunoprecipitation. KEY FINDINGS Circ_0029589 level was enhanced in ox-LDL-challenged VSMCs. Circ_0029589 interference constrained cell proliferation, migration and invasion in ox-LDL-challenged VSMCs. miR-214-3p was targeted by circ_0029589 and miR-214-3p knockdown weakened the suppressive function of circ_0029589 silence on VSMCs proliferation, migration and invasion. STIM1 was targeted via miR-214-3p and miR-214-3p could suppress VSMCs proliferation, migration and invasion via decreasing STIM1. Moreover, circ_0029589 modulated STIM1 level by miR-214-3p. SIGNIFICANCE Circ_0029589 knockdown repressed proliferation, migration and invasion of VSMCs challenged via ox-LDL by regulating miR-214-3p and STIM1, indicating that circ_0029589 might play important role in atherosclerosis.

Abstract
Cellular senescence is an important mechanism of autonomous tumor suppression, while its consequence such as the senescence-associated secretory phenotype (SASP) may drive tumorigenesis and age-related diseases. Therefore, controlling the cell fate optimally when encountering senescence stress is helpful for anti-cancer or anti-aging treatments. To identify genes essential for senescence establishment or maintenance, we carried out a CRISPR-based screen with a deliberately designed single-guide RNA (sgRNA) library. The library comprised of about 12,000 kinds of sgRNAs targeting 1378 senescence-associated genes selected by integrating the information of literature mining, protein-protein interaction network, and differential gene expression. We successfully detected a dozen gene deficiencies potentially causing senescence bypass, and their phenotypes were further validated with a high true positive rate. RNA-seq analysis showed distinct transcriptome patterns of these bypass cells. Interestingly, in the bypass cells, the expression of SASP genes was maintained or elevated with CHEK2, HAS1, or MDK deficiency; but neutralized with MTOR, CRISPLD2, or MORF4L1 deficiency. Pathways of some age-related neurodegenerative disorders were also downregulated with MTOR, CRISPLD2, or MORF4L1 deficiency. The results demonstrated that disturbing these genes could lead to distinct cell fates as a consequence of senescence bypass, suggesting that they may play essential roles in cellular senescence.

Abstract
Aim: We aimed to identify the expression profile and role of circular RNAs (circRNAs) in coronary heart disease (CHD). Materials & methods: We performed sequence analysis of circRNAs in peripheral blood mononuclear cells of 70 CHD patients and 30 controls. Eight selected circRNAs were validated using quantitative real-time polymerase chain reaction (qRT-PCR) in human atherosclerotic coronary arteries. Results: In total, 2283 downregulated and 85 upregulated circRNAs were identified in CHD. Parental genes of top 100 dysregulated-circRNAs are related to metabolism and protein modification, and 12 circRNAs might upregulate their CHD-related parental genes through miRNA sponges. Of the eight circRNAs validated in atherosclerotic coronary arteries by qRT-PCR, six were consistent with sequencing results of peripheral blood mononuclear cells. Conclusion: As potential ceRNAs, dysregulated circRNAs may be involved in CHD pathophysiology.

Abstract
Background Protease-Activated Receptor 2 (PAR2), a G-protein-coupled receptor, has been proved to be enhanced in human coronary atherosclerosis lesions. We aimed to investigate whether PAR2 actively participates in the atherosclerosis process. Material/Methods PAR2 expression was assessed in blood samples by RT-qPCR from healthy controls and patients with atherosclerosis. Human vascular smooth muscle cells (VSMCs) were treated with oxidative low-density lipoprotein (ox-LDL). After PAR2 overexpression by transfection, cell proliferation was determined by CCK-8, and cell migration was evaluated by Transwell assay. The protein expressions associated with cell growth and migration were measured by Western blot. The distribution of α-SMA in VSMCs was evaluated by immunofluorescence. Results Expression of PAR2 was higher in patients with atherosclerosis compared with normal controls. PAR2 mRNA and protein expression was increased in ox-LDL-treated VSMCs compared with control cells. Induced overexpression of PAR2 in VSMCs led to a reduction in α-SMA expression compared to controls. In addition, PAR2 overexpression caused increased migration compared to normal controls, and upregulated MMP9 and MMP14 expression. PAR-2 overexpression promoted cell proliferation compared to control cells, and increased expression levels of CDK2, and CyclinE1, but reduced levels of p27. We preliminary explored the potential mechanism of PAR2, and results showed that overexpression of PAR2 increased expression levels of VEGFA and Angiopoietin 2 compared to controls. Moreover, overexpression of PAR2 enhanced production of tissue factor and IL-8 compared to normal controls. Conclusions PAR2 promotes cell proliferation and disrupts the quiescent condition of VSMCs, which may be a potential therapeutic target for atherosclerosis.

Abstract
The transient receptor potential melastatin-subfamily member 7 (TRPM7) is a ubiquitously expressed chanzyme that possesses an ion channel permeable to the divalent cations Mg2+, Ca2+, and Zn2+, and an α-kinase that phosphorylates downstream substrates. TRPM7 and its homologue TRPM6 have been implicated in a variety of cellular functions and is critically associated with intracellular signaling, including receptor tyrosine kinase (RTK)-mediated pathways. Emerging evidence indicates that growth factors, such as EGF and VEGF, signal through their RTKs, which regulate activity of TRPM6 and TRPM7. TRPM6 is primarily an epithelial-associated channel, while TRPM7 is more ubiquitous. In this review we focus on TRPM7 and its association with growth factors, RTKs, and downstream kinase signaling. We also highlight how interplay between TRPM7, Mg2+ and signaling kinases influences cell function in physiological and pathological conditions, such as cancer and preeclampsia.

Abstract
In our previous study, the oxLDL/β2GPI/anti-β2GPI complex was demonstrated to further enhance the foam cell formation and migration of VSMC, as well as the expression of inflammatory cytokines, via the TLR4/NF-κB pathway. However, sparse information is available on other pro-atherogenic pathogenic effects of the oxLDL/β2GPI/anti-β2GPI complex, such as effects on proliferation and apoptosis. In the present study, we focused on the biphasic effects and underlying mechanisms of the oxLDL/β2GPI/anti-β2GPI complex on VSMC survival. The data showed that short exposure to the oxLDL/β2GPI/anti-β2GPI complex could activate NF-κB and ERK1/2 pathways and stimulate cell proliferation in VSMC. In contrast, longer exposure increased the level of p38 pathway activation and cell apoptosis. Additionally, the promotion effect of the oxLDL/β2GPI/anti-β2GPI complex on both proliferation and apoptosis, as well as signaling pathway activation, was stronger than that of the other control groups. The use of selective blockers showed that TLR4/NF-κB and ERK1/2 partly mediated oxLDL/β2GPI/anti-β2GPI complex-induced proliferation and had an inhibitory effect on complex-stimulated apoptosis. Conversely, TLR2/p38 partly mediated oxLDL/β2GPI/anti-β2GPI complex-induced apoptosis and had a negative effect on complex-stimulated proliferation. Specific inhibitors of NF-κB and ERK1/2 activation could augment the oxLDL/β2GPI/anti-β2GPI complex-induced phosphorylation of p38 and vice versa. Under pretreatment with NADPH oxidase inhibitors, intracellular ROS generation was confirmed to participate in oxLDL/β2GPI/anti-β2GPI complex-induced proliferation and apoptosis, as well as the phosphorylation of NF-κB and MAPKs. Taken together, our data clearly revealed that the oxLDL/β2GPI/anti-β2GPI complex had biphasic effects on VSMC survival, partly mediated by ROS-induced NF-κB and MAPKs activation. The TLR4/NF-κB and TLR2/p38 pathways played supporting roles in this dual effects-initiated signal network, and there is a trade-off relationship between the phosphorylation of NF-κB, ERK1/2 and p38. The dual effects of the oxLDL/β2GPI/anti-β2GPI complex on VSMC survival contribute to the development of the structure typical of atherosclerotic lesions, particularly focal excessive growth alternating with necrosis.

MiR-31 Mediates Inflammatory Signaling to Promote Re-Epithelialization during Skin Wound Healing. J Invest Dermatol 2018; 138:2253-2263. [PMID: 29605672 PMCID: PMC6153075 DOI: 10.1016/j.jid.2018.03.1521] [Citation(s) in RCA: 71] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2017] [Revised: 03/16/2018] [Accepted: 03/19/2018] [Indexed: 11/18/2022]
Abstract
Wound healing is essential for skin repair after injury, and it consists of hemostasis, inflammation, re-epithelialization, and remodeling phases. Successful re-epithelialization, which relies on proliferation and migration of epidermal keratinocytes, requires a reduction in tissue inflammation. Therefore, understanding the molecular mechanism underlying the transition from inflammation to re-epithelialization will help to better understand the principles of wound healing. Currently, the in vivo functions of specific microRNAs in wound healing are not fully understood. We observed that miR-31 expression is strongly induced in wound edge keratinocytes, and is directly regulated by the activity of NF-κB and signal transducer and activator of transcription 3 signaling pathways during the inflammation phase. We used miR-31 loss-of-function mouse models to demonstrate that miR-31 promotes keratinocyte proliferation and migration. Mechanistically, miR-31 activates the Ras/mitogen-activated protein kinase signaling by directly targeting Rasa1, Spred1, Spred2, and Spry4, which are negative regulators of the Ras/mitogen-activated protein kinase pathway. Knockdown of these miR-31 targets at least partially rescues the delayed scratch wound re-epithelialization phenotype observed in vitro in miR-31 knockdown keratinocytes. Taken together, these findings identify miR-31 as an important cell-autonomous mediator during the transition from inflammation to re-epithelialization phases of wound healing, suggesting a therapeutic potential for miR-31 in skin injury repair.

Abstract
Metabolic syndrome (MetS) is a highly prevalent disorder which can be used to identify individuals with a higher risk for cardiovascular disease and type 2 diabetes. This metabolic syndrome is characterized by a combination of physiological, metabolic, and molecular alterations such as insulin resistance, dyslipidemia, and central obesity. The low-density lipoprotein receptor-related protein 1 (LRP1—A member of the LDL receptor family) is an endocytic and signaling receptor that is expressed in several tissues. It is involved in the clearance of chylomicron remnants from circulation, and has been demonstrated to play a key role in the lipid metabolism at the hepatic level. Recent studies have shown that LRP1 is involved in insulin receptor (IR) trafficking and intracellular signaling activity, which have an impact on the regulation of glucose homeostasis in adipocytes, muscle cells, and brain. In addition, LRP1 has the potential to inhibit or sustain inflammation in macrophages, depending on its cellular expression, as well as the presence of particular types of ligands in the extracellular microenvironment. In this review, we summarize existing perspectives and the latest innovations concerning the role of tissue-specific LRP1 in lipoprotein and glucose metabolism, and examine its ability to mediate inflammatory processes related to MetS and atherosclerosis.

Neuroprotective effect of olfactory ensheathing cells co-transfected with Nurr1 and Ngn2 in both in vitro and in vivo models of Parkinson's disease. Life Sci 2017; 194:168-176. [PMID: 29291419 DOI: 10.1016/j.lfs.2017.12.038] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Revised: 12/20/2017] [Accepted: 12/29/2017] [Indexed: 12/16/2022]
Abstract
AIMS The aim of the study is to evaluate the neuroprotective effects of olfactory ensheathing cells (OECs) with the overexpression of nuclear receptor-related factor 1 (Nurr1) and neurogenin 2 (Ngn2) in experimental models of Parkinson's disease (PD) and to elucidate the potential mechanism underlying the neuroprotective effects of OECs-Nurr1-Ngn2. MATERIALS AND METHODS In vitro study, OECs-Nurr1-Ngn2 conditioned medium (CM) was added to MPP+-treated PC12 cells for 24h, and then the viability of PC12 cells, oxidative stress and apoptosis were detected. In vivo study, 48 male Sprague-Dawley (SD) rats were randomly divided into four groups. OECs/VMCs and OECs-Nurr1-Ngn2/VMCs groups were transplanted with 2×105 cells each of OECs or OECs-Nurr1-Ngn2 and VMCs into the right striatum one week after a unilateral 6-OHDA lesion. Control and PD groups were injected with 0.9% NaCl and 0.2% ascorbic acid into the same region. Rotational behavior was determined at 2, 4, 6 and 8weeks after injection or implantation in all groups. Neuronal differentiation markers, oxidative stress- and apoptosis-related indicators were detected at 8weeks post-grafting. KEY FINDINGS OECs-Nurr1-Ngn2 increased the viability of PC12 cells, inhibited oxidative stress and apoptosis, and these effects could be reversed by pre-treatment of k252a, a TrkB receptor inhibitor. The behavioral deficits of PD rat were ameliorated by the transplantation of OECs-Nurr1-Ngn2/VMCs. SIGNIFICANCE These results suggest that OECs-Nurr1-Ngn2 exhibits substantial neuroprotective, anti-oxidant, and anti-apoptotic effects against PD via the up-regulation of the neurotrophic factor-TrkB pathway.

Abstract
Aortic valve (AoV) calcification is common in aged populations. Its subsequent aortic stenosis has been linked with increased morbidity, but still has no effective pharmacological intervention. Our previous data show endoplasmic reticulum (ER) stress is involved in AoV calcification. Here, we investigated whether deficiency of ER stress downstream effector CCAAT/enhancer-binding protein homology protein (CHOP) may prevent development of AoV calcification. AoV calcification was evaluated in Apoe-/- mice (n = 10) or in mice with dual deficiencies of ApoE and CHOP (Apoe-/- CHOP-/- , n = 10) fed with Western diet for 24 weeks. Histological and echocardiographic analysis showed that genetic ablation of CHOP attenuated AoV calcification, pro-calcification signaling activation, and apoptosis in the leaflets of Apoe-/- mice. In cultured human aortic valvular interstitial cells (VIC), we found oxidized low-density lipoprotein (oxLDL) promoted apoptosis and osteoblastic differentiation of VIC via CHOP activation. Using conditioned media (CM) from oxLDL-treated VIC, we further identified that oxLDL triggered osteoblastic differentiation of VIC via paracrine pathway, while depletion of apoptotic bodies (ABs) in CM suppressed the effect. CM from oxLDL-exposed CHOP-silenced cells prevented osteoblastic differentiation of VIC, while depletion of ABs did not further enhance this protective effect. Overall, our study indicates that CHOP deficiency protects against Western diet-induced AoV calcification in Apoe-/- mice. CHOP deficiency prevents oxLDL-induced VIC osteoblastic differentiation via preventing VIC-derived ABs releasing.

Abstract
This study investigated the change of transient receptor potential cation channel subfamily M member 7 (TRPM7) expression in rat aortic vascular smooth muscle cells (RAoSMCs) treated with a high concentration of d-glucose (HG) and its role in promoting the proliferative phenotype of RAoSMCs. Chronic exposure to HG increased TRPM7 protein expression and TRPM7 whole-cell currents in RAoSMCs. By contrast, RAoSMC exposure to high concentration of l-glucose and mannital exhibited no such effect. Mechanistically, HG treatment elevated TRPM7 expression by increasing oxidative stress. Data also demonstrated that HG significantly promoted RAoSMC proliferation. In addition, as indicated by the changes of the expression of VSMC differentiation marker molecules, phenotype switching of RAoSMCs occurred during exposing to HG. TRPM7 knockdown partially blocked the HG effect on phenotype switching and RAoSMC proliferation. This phenomenon was achieved through inhibiting the mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) kinase (MEK)-ERK signaling pathway. These observations suggest that reactive oxygen species-TRPM7-ERK1/2 axis plays an important role in hyperglycemia-induced development of the proliferative phenotype in RAoSMC.

Abstract
BACKGROUND/AIMS The differentiation efficiency of bone marrow mesenchymal stem cells (BM-MSCs) is low in vivo after transplantation. Therefore, it is necessary to look for effective reagents for enhancing cardiac differentiation of BM-MSCs. It has been reported that cardiac differentiation of stem cells depends on the activation of extracellular signal-regulated protein 1/2 (ERK1/2) signaling. Oxidized low-density lipoprotein (ox-LDL) is a potent reagent for ERK1/2 activation. This indicates that ox-LDL may be a potential reagent to stimulate cardiac differentiation of stem cells. In this study, we investigated the effect of ox-LDL on cardiac differentiation of BM-MSCs and its relationship with ERK1/2 signaling. METHODS BM-MSCs were isolated from mouse bone marrow, cultured in DMEM supplemented with 15% FBS, and passaged up to the 3rd passage. Following culture with 5 μg/mL ox-LDL for 3 weeks, the cardiac differentiation of the 3rd passage BM-MSCs was identified by immunostaining, Western blotting, and RT-PCR assays for measuring the expression of cardiac-specific markers. To further explore the role of ERK1/2 signaling in cardiac differentiation of BM-MSCs, we simultaneously exposed BM-MSCs to ERK1/2 inhibitor (U0126) and ox-LDL, and identified the cardiac differentiation again. RESULTS The expressions of cardiac-specific markers including α-cardiac actin, α-MHC, β-MHC, ANP, and BNP were markedly increased in BM-MSCs following treatment with ox-LDL (P < .05), which indicates a directional differentiation of BM-MSCs to cardiac cells. Further, ox-LDL could also activate ERK1/2 in BM-MSCs, and application of U0126 markedly inhibited ox-LDL-induced cardiac transformation of BM-MSCs. CONCLUSIONS Ox-LDL induces cardiac differentiation of BM-MSCs via activation of ERK1/2 signaling.

Abstract
Vascular smooth muscle cell (VSMC) proliferation is a major contributor to atherosclerosis. This study investigated the inhibitory effects of oleanolic acid (OA) against oxidized low-density lipoprotein (ox-LDL)-induced VSMC proliferation in A7r5 cells and explored underlying molecular mechanism. The cell proliferation was quantified with cell counting kit-8 (CCK-8), in which ox-LDL significantly increased A7r5 cells proliferation, while OA pretreatment effectively alleviated such changes without inducing overt cytotoxicity, as indicated by lactate dehydrogenase (LDH) assay. Quantitative real-time RT-PCR (qRT-PCR) and Western blotting revealed increased UCP2 and FGF-2 expression levels as well as decreased p53 and TSP-1 expression levels in A7r5 cells following ox-LDL exposure, while OA pretreatment reversed such changes. Furthermore, inhibiting UCP2 with genipin remarkably reversed the changes in the expression levels of FGF-2, p53, and TSP-1 induced by ox-LDL exposure; silencing FGF-2 with siRNA did not significantly change the expression levels of UCP2 but effectively reversed the changes in the expression levels of p53 and TSP-1, and activation of p53 with PRIMA-1 only significantly affected the changes in the expression levels of TSP-1, but not in UCP2 or FGF-2, suggesting a UCP-2/FGF-2/p53/TSP-1 signaling in A7r5 cells response to ox-LDL exposure. Additionally, co-treatment of OA and genipin exhibited similar effects to the expression levels of UCP2, FGF-2, p53, and TSP-1 as OA or genipin solo treatment in ox-LDL-exposed A7r5 cells, suggesting the involvement of UCP-2/FGF-2/p53/TSP-1 in the mechanism of OA. In conclusion, OA inhibits ox-LDL-induced VSMC proliferation in A7r5 cells, the mechanism involves the changes in UCP-2/FGF-2/p53/TSP-1.

Abstract
The human TRP protein family comprises a family of 27 cation channels with diverse permeation and gating properties. The common theme is that they are very important regulators of intracellular Ca2+ signaling in diverse cell types, either by providing a Ca2+ influx pathway, or by depolarising the membrane potential, which on one hand triggers the activation of voltage-gated Ca2+ channels, and on the other limits the driving force for Ca2+ entry. Here we focus on the role of these TRP channels in vascular smooth muscle and cardiac striated muscle. We give an overview of highlights from the recent literature, and highlight the important and diverse roles of TRP channels in the pathophysiology of the cardiovascular system. The discovery of the superfamily of Transient Receptor Potential (TRP) channels has significantly enhanced our knowledge of multiple signal transduction mechanisms in cardiac muscle and vascular smooth muscle cells (VSMC). In recent years, multiple studies have provided evidence for the involvement of these channels, not only in the regulation of contraction, but also in cell proliferation and remodeling in pathological conditions. The mammalian family of TRP cation channels is composed by 28 genes which can be divided into 6 subfamilies groups based on sequence similarity: TRPC (Canonical), TRPM (Melastatin), TRPML (Mucolipins), TRPV (Vanilloid), TRPP (Policystin) and TRPA (Ankyrin-rich protein). Functional TRP channels are believed to form four-unit complexes in the plasma, each of them expressed with six transmembrane domain and intracellular N and C termini. Here we review the current knowledge on the expression of TRP channels in both muscle types, and discuss their functional properties and role in physiological and pathophysiological processes.

Abstract
The profound inhibitory effect of Tanshinone IIA (Tan IIA) on atherosclerosis has been demonstrated, whereas the latent mechanism is not completely cleared. This study aimed to investigate the cellular and molecular mechanisms underlying Tan IIA protecting against atherosclerosis. Oil Red O staining and ELISA assay showed that Tan IIA suppressed the progress of atherosclerosis and reduced the levels of inflammatory cytokines in serum of apolipoprotein E deficient (ApoE -/- ) mice. Flow cytometry assay revealed that Tan IIA inhibited oxidized LDL (ox-LDL)-induced apoptosis of VSMCs. MTT and transwell assay indicated that Tan IIA suppressed the ox-LDL-stimulated proliferation and migration of RAW264.7 cells. Moreover, Tan IIA ameliorated inflammatory cytokine upregulation elicited by ox-LDL in RAW264.7 cells. Additionally, Tan IIA inhibited the apoptosis of VSMCs and decreased the levels of MMP-2, MMP-9 in ApoE-/- mice. In conclusion, our study demonstrated Tan IIA suppressed the progression of atherosclerosis by inhibiting vascular inflammation, apoptosis of VSMCs and proliferation and migration of macrophages induced by ox-LDL.

Abstract
Transient receptor potential melastatin 7 (TRPM7), a bifunctional channel protein owning both cation permeability and kinase activity, plays an important role in the pathophysiological process of many cell types, such as vascular smooth muscle cells, human glioma cells and mouse cortical astrocytes. However, whether TRPM7 channels play a key role in the functional change of cardiac fibroblasts (CFs) induced by angiotensin II (Ang II) remains unknown. Using Cell Counting Kit-8 (CCK-8) assay, immunofluorescence assay, western blot analysis, RT-qPCR, RNA interference (RNAi) and whole-cell patch-clamp techniques, the present study aimed to explore the role of TRPM7 channels in the proliferation, differentiation and collagen synthesis of CFs induced by Ang II. Our data showed that Ang II time-dependently increased TRPM7 expression and TRPM7 currents in the CFs. Downregulation of TRPM7 attenuated the TRPM7 current density, and inhibited the proliferation, differentiation and collagen synthesis of CFs induced by Ang II. Our results identified the TRPM7 channel as a pivotal member associated with the functional change of CFs induced by Ang II, and suggest that the TRPM7 channel may represent a promising therapeutic strategy for the treatment of fibrosis-related cardiac diseases.

Abstract
Excessive proliferation of vascular smooth muscle cells is one of the main pathological processes leading to atherosclerosis and intimal hyperplasia after vascular interventional therapy. Our previous study has shown that interferon-γ inducible protein-10 contributes to the proliferation of vascular smooth muscle cell. However, the underlying mechanisms remain unclear. Extracellular signal-regulated kinase 1/2, serine/threonine kinase Akt, and cAMP response element binding protein are signaling pathways, which are considered to play important roles in the processes of vascular smooth muscle cell proliferation. Moreover, chemokine receptor 3 and Toll-like receptor 4 are potential receptors of inducible protein-10 in this process. In the present study, IP-10 was found to directly induce vascular smooth muscle cell proliferation, and exposure to inducible protein-10 activated extracellular signal-regulated kinase 1/2, serine/threonine kinase, and cAMP response element binding protein signaling. Inhibitor of extracellular signal-regulated kinase 1/2, rather than inhibitor of serine/threonine kinase, inhibited the phosphorylation of cAMP response element binding protein and reduced inducible protein-10-stimulated vascular smooth muscle cell proliferation. Knockdown of cAMP response element binding protein by siRNA inhibited inducible protein-10-induced vascular smooth muscle cell proliferation. Moreover, anti-CXCR3 IgG, instead of anti-Toll-like receptor 4 IgG, reduced inducible protein-10-induced vascular smooth muscle cell proliferation and inducible protein-10-stimulated extracellular signal-regulated kinase 1/2 and cAMP response element binding protein activation. Together, these results indicate that inducible protein-10 promotes vascular smooth muscle cell proliferation via chemokine receptor 3 and activation of extracellular signal-regulated kinase 1/2 inducible protein-10-induced vascular smooth muscle cell proliferation. These data provide important targets for future studies to modulate atherosclerosis and restenosis after vascular interventional therapy.

Microvesicles Derived from Inflammation-Challenged Endothelial Cells Modulate Vascular Smooth Muscle Cell Functions. Front Physiol 2017; 7:692. [PMID: 28127288 PMCID: PMC5226944 DOI: 10.3389/fphys.2016.00692] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2016] [Accepted: 12/27/2016] [Indexed: 12/13/2022] Open
Abstract
Purpose: Microvesicles (MV) can modulate the function of recipient cells by transferring their contents. Our previous study highlighted that MV released from tumor necrosis factor-α (TNF-α) plus serum deprivation (SD)-stimulated endothelial progenitor cells, induce detrimental effects on endothelial cells. In this study, we investigated the potential effects of endothelial MV (EMV) on proliferation, migration, and apoptosis of human brain vascular smooth cells (HBVSMC). Methods: EMV were prepared from human brain microvascular endothelial cells (HBMEC) cultured in a TNF-α plus SD medium. RNase-EMV were made by treating EMV with RNase A for RNA depletion. The proliferation, apoptosis and migration abilities of HBVSMC were determined after co-culture with EMV or RNase-EMV. The Mek1/2 inhibitor, PD0325901, was used for pathway analysis. Western blot was used for analyzing the proteins of Mek1/2, Erk1/2, phosphorylation Erk1/2, activated caspase-3 and Bcl-2. The level of miR-146a-5p was measured by qRT-PCR. Results: (1) EMV significantly promoted the proliferation and migration of HBVSMC. The effects were accompanied by an increase in Mek1/2 and p-Erk1/2, which could be abolished by PD0325901; (2) EMV decreased the apoptotic rate of HBVSMC by approximately 35%, which was accompanied by cleaved caspase-3 down-regulation and Bcl-2 up-regulation; (3) EMV increased miR-146a-5p level in HBVSMC by about 2-folds; (4) RNase-treated EMV were less effective than EMV on HBVSMC activities and miR-146a-5p expression. Conclusion: EMV generated under inflammation challenge can modulate HBVSMC function and fate via their carried RNA. This is associated with activation of theMek1/2/Erk1/2 pathway and caspase-3/Bcl-2 regulation, during which miR-146a-5p may play an important role. The data suggest that EMV derived from inflammation-challenged endothelial cells are detrimental to HBVSMC homeostatic functions, highlighting potential novel therapeutic targets for vascular diseases.
