Abstract
Atherosclerosis (AS) is the primary reason behind cardiovascular diseases, leading to approximately one-third of global deaths. Developing a novel multi-model probe to detect AS is urgently required. Macrophages are the primary cells from which AS genesis occurs. Utilizing natural macrophage membranes coated on the surface of nanoparticles is an efficient delivery method to target plaque sites. Herein, Fe3 O4 -Cy7 nanoparticles (Fe3 O4 -Cy7 NPs), functionalized using an M2 macrophage membrane and a liposome extruder for Near-infrared fluorescence and Magnetic resonance imaging, are synthesized. These macrophage membrane-coated nanoparticles (Fe3 O4 @M2 NPs) enhance the recognition and uptake using active macrophages. Moreover, they inhibit uptake using inactive macrophages and human coronary artery endothelial cells. The macrophage membrane-coated nanoparticles (Fe3 O4 @M0 NPs, Fe3 O4 @M1 NPs, Fe3 O4 @M2 NPs) can target specific sites depending on the macrophage membrane type and are related to C-C chemofactor receptor type 2 protein content. Moreover, Fe3 O4 @M2 NPs demonstrate excellent biosafety in vivo after injection, showing a significantly higher Fe concentration in the blood than Fe3 O4 -Cy7 NPs. Therefore, Fe3 O4 @M2 NPs effectively retain the physicochemical properties of nanoparticles and depict reduced immunological response in blood circulation. These NPs mainly reveal enhanced targeting imaging capability for atherosclerotic plaque lesions.

Abstract
Objectives To investigate the role of nuclear factor-kappa B (NF-κB) performed in cell proliferation and apoptosis of vascular smooth muscle cells (VSMCs), and to assess the mechanisms. Methods Human aorta VSMCs were divided into control, NF-κB inhibitor, NF-κB overexpression + NF-κB inhibitor, control vector + NF-κB inhibitor, NF-κB overexpression, and control vector groups. NF-κB overexpression vector was constructed and transfected into VSMCs. Proliferation of VSMCs in each group was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide. Apoptosis of VSMCs was detected by flow cytometry. The expression of NF-κB, FasL, and hypertension-related gene (HRG-1) was measured by Western blotting. Results NF-κB overexpression vector was constructed correctly by restriction endonuclease, and the results showed that the activation of NF-κB could inhibit the proliferation of VSMCs. The results of flow cytometry also confirmed that NF-κB overexpression promoted apoptosis of VSMCs. Mechanically, NF-κB overexpression could up-regulate the expression of FasL and HRG-1. Conclusions NF-κB overexpression promotes apoptosis and inhibits cell proliferation of VSMCs. The mechanisms might be regulated by promoting FasL and HRG-1 expression.

Abstract
Atherosclerosis involves the proliferation and migration of vascular smooth muscle cells (VSMCs). The migration of VSMCs from the media into the intima and their subsequent proliferation are important processes in neointima formation in atherosclerosis and restenosis after percutaneous coronary interventions. Acarbose, an alpha-glucosidase inhibitor, has been demonstrated to not affect serum levels of glucose and decrease the progression of intima-media thickening in rabbits fed with a high cholesterol diet (HCD). We previously showed that increased Ras protein levels enhanced the migration of TNF-α treated A7r5 cells. The aim of this study was to determine the inhibitory effects of acarbose on Ras expression in A7r5 cells. Acarbose also inhibited the phosphorylation of focal adhesion kinase (FAK) and Akt, activities of the matrix metalloproteinases (MMPs) MMP-2 and MMP-9, and protein expressions of small G proteins (Ras, Cdc42, RhoA, and Rac1) in a dose-dependent manner. We also found that acarbose could effectively inhibit the proliferation and migration of RasG12V A7r5 cells by blocking small G proteins and phosphoinositide-3-kinase (PI3K)/Akt signaling. These studies demonstrated that acarbose could theoretically decrease atherosclerosis by targeting Ras signaling.

miR-200c-SUMOylated KLF4 feedback loop acts as a switch in transcriptional programs that control VSMC proliferation. J Mol Cell Cardiol 2015; 82:201-12.

Abstract
The regulation of vascular smooth muscle cell (VSMC) proliferation is an important issue because it has major implications for the prevention of pathological vascular conditions. Using microRNA array screen, we found the expression levels of 200 unique miRNAs in hyperplasic tissues. Among them, miR-200c expression substantially was down-regulated. The objective of this work was to assess the function of miR-200c and SUMOylated Krϋppel-like transcription factor 4 (KLF4) in the regulation of VSMC proliferation in both cultured cells and animal models of balloon injury. Under basal conditions, we found that miR-200c inhibited the expression of KLF4 and the SUMO-conjugating enzyme Ubc9. Upon PDGF-BB treatment, Ubc9 interacted with and promoted the SUMOylation of KLF4, which allowed the recruitment of transcriptional corepressors (e.g., nuclear receptor corepressor (NCoR) and HDAC2) to the miR-200c promoter. The reduction in miR-200c levels led to increased target gene expression (e.g., Ubc9 and KLF4), which further repressed miR-200c levels and accelerated VSMC proliferation. These results demonstrate that induction of a miR-200c-SUMOylated KLF4 feedback loop is a significant aspect of the PDGF-BB proliferative response in VSMCs and that targeting Ubc9 represents a novel approach for the prevention of restenosis.

Abstract
Atherosclerosis (AS) is a complicated progress, involving many types of cells. Although the exact mechanisms of progression of atherosclerosis are uncertain, the balance of vascular smooth muscle cells (VSMCs) proliferation and apoptosis appears to play a pivotal role in the pathogenesis and progression of atherosclerosis, and much discussion has been undertaken to elucidate the detailed mechanisms, relevant gene expression and transduction pathways. Drug treatment has focused on ameliorating atherosclerosis. Some researchers have indicated that inhibiting VSMCs proliferation is involved in attenuating atherosclerosis. Luteolin is a kind of flavonoids naturally occurring in many plants and possesses beneficial effects on cardiovascular diseases. Luteolin can reduce VSMCs’ proliferation and migration and this reduction is stimulated by several factors. The aim of this review is to summarize the existing inhibitory effects and mechanisms of luteolin on proliferation and migration of VSMCs, and consider whether luteolin may be a potential candidate for preventing and treating atherosclerosis.

Xu Z, Lan T, Wu W, Wu Y. The effects of ginsenoside Rb1 on endothelial damage and ghrelin expression induced by hyperhomocysteine. J Vasc Surg 2011; 53:156-64. [PMID: 20801605 DOI: 10.1016/j.jvs.2010.06.170] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2010] [Revised: 06/16/2010] [Accepted: 06/27/2010] [Indexed: 01/25/2023]
Abstract
OBJECTIVE Studies have indicated that ginsenoside Rb1 and ghrelin could both prevent homocysteine (Hcy)-induced endothelial dysfunction through the endothelial nitric oxide synthase (eNOS)/nitric oxide (NO) mechanism. This study investigated whether endogenous ghrelin mediates the endothelial protection of ginsenosidee Rb1 through in vitro and in vivo experiments. METHODS Rats were randomized into a control group, a hyperhomocysteine (HHcy) model group with a high methionine diet, a ginsenosides (GS) group, and HHcy plus GS group. Plasma ghrelin was detected by enzyme-linked immunosorbent assay. Aortic rings for control and HHcy groups were treated with ghrelin or not. Endothelium-dependent vasodilatation function was evaluated by the aortic ring assay, and the structural changes were visualized by hematoxylin and eosin staining. Human umbilical vein endothelial cells (HUVECs) were cultured, and the experimental conditions were optimized according to NO production. After treatment, the NO, ghrelin, and von Willebrand factor (vWF) levels in the media were detected and analyzed with linear regression. Ghrelin and eNOS expression were observed by cell immunohistochemical staining. Ghrelin receptor antagonist was used to detect the mechanism of ginsenoside Rb1 on NO production, which was reflected by diacetylated 4,5-diaminofluorescein-2 diacetate fluorescence. RESULTS In vivo experiments demonstrated that plasma ghrelin levels in the HHcy group were significantly elevated vs controls (P < .05) and were significantly increased in the HHcy plus GS group (P < .01). Compared with control, endothelium-dependent vasodilatation function was greatly reduced in the HHcy group (P < .01), which was significantly increased in HHcy plus ghrelin group compared with HHcy group (P < .01). The arterial walls of HHcy group exhibited characteristic pathologic changes, which were repaired in HHcy plus ghrelin group. In vivo, compared with Hcy (200 μM) group, HUVECs pretreated with ginsenoside Rb1 (10 μM) for 30 minutes showed significant increases in NO and ghrelin levels and evident reduction in vWF levels. Linear regression analysis demonstrated that ghrelin levels were significantly positively correlated with NO levels and significantly negatively correlated with vWF levels. The addition of Rb1 to Hcy also greatly reversed Hcy-induced downregulation of ghrelin and eNOS expression. Ghrelin inhibition significantly abolished the upregulation of NO levels induced by Rb1. CONCLUSION Ghrelin can prevent Hcy-induced vascular endothelial dysfunction and structural damage. The compensatory elevation of plasma ghrelin levels in an Hcy-induced endothelial injury model may be a protective response. Ginsenoside Rb1 can significantly stimulate the ghrelin endocrine to inhibit endothelial injury. Ginsenoside also upregulates the NO signaling pathway reduced by Hcy through the ghrelin molecular mechanism.
