Abstract
Atherosclerosis, one of the life-threatening cardiovascular diseases (CVDs), has been demonstrated to be a chronic inflammatory disease, and inflammatory and immune processes are involved in the origin and development of the disease. Toll-like receptors (TLRs), a class of pattern recognition receptors that trigger innate immune responses by identifying pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs), regulate numerous acute and chronic inflammatory diseases. Recent studies reveal that TLRs have a vital role in the occurrence and development of atherosclerosis, including the initiation of endothelial dysfunction, interaction of various immune cells, and activation of a number of other inflammatory pathways. We herein summarize some other inflammatory signaling pathways, protein molecules, and cellular responses associated with TLRs, such as NLRP3, Nrf2, PCSK9, autophagy, pyroptosis and necroptosis, which are also involved in the development of AS. Targeting TLRs and their regulated inflammatory events could be a promising new strategy for the treatment of atherosclerotic CVDs. Novel drugs that exert therapeutic effects on AS through TLRs and their related pathways are increasingly being developed. In this article, we comprehensively review the current knowledge of TLR signaling pathways in atherosclerosis and actively seek potential therapeutic strategies using TLRs as a breakthrough point in the prevention and therapy of atherosclerosis.

Abstract
OBJECTIVE Lipopolysaccharide-induced tumor necrosis factor-α factor (LITAF) protein is a newly discovered inflammatory protein. This study aims to study the role of LITAF in the formation of atherosclerosis. METHODS A total of 10 C57BL/6J mice and 10 C57BL/6J mice with knockout of LITAF gene (C57BL/6J-LITAF-) were divided into two groups: the control group and the LITAF-/- group. The animals were accommodated for 16 weeks and then euthanized with their hearts and aortas isolated thereafter. Next, the roots of the mouse aorta were cryosectioned and stained with Oil Red O staining and immunohistochemical staining (CD68, α-SMA, and Masson), respectively. The area of Oil Red O staining and the proportion of positive expression after immunohistochemical staining were then compared between the control and LITAF-/- groups. At the same time, the blood of mice was collected for the extraction of proteins and RNA. The proteins and RNA were used to detect the expression of major molecules of the NF-κB inflammatory pathway in mice in the control group and the LITAF-/- group by Western blotting and RT-PCR. RESULTS Oil Red O staining of the aortic root sections of the mice in each group revealed that the area of atherosclerotic plaques in the LITAF-/- group was substantially lower than that in the control group (P<0.05). Moreover, immunohistochemical staining determined that the expression level of α-SMA and CD68 in the LITAF-/- group was significantly lower than that in the control group, whereas the results were reversed following Masson staining (P<0.05). The expression levels of P65 and caspase 3 were significantly lower in the LITAF-/- group than in the control group (P<0.05), whereas the expression level of IκB was higher in the LITAF-/- group. CONCLUSION LITAF might participate in the formation of atherosclerotic plaque through the NF-κB pathway and play a promoting role in the formation of atherosclerosis.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 119:155002. [PMID: 37572566 DOI: 10.1016/j.phymed.2023.155002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 07/05/2023] [Accepted: 07/27/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND Inflammation is critical in the pathophysiology of atherosclerosis (AS). The aim of this study was to investigate the protective effect of salvianolic acid B (Sal B) on AS and to explore the molecular mechanism of tumor necrosis factor-α (TNF-α)-induced damage in human umbilical vein endothelial cells (HUVECs). METHODS In vivo studies, LDLR-/- mice were fed a high-fat diet (HFD) for 14 weeks to establish an AS model to evaluate the protective effect of Sal B on the development of AS. Total cholesterol (TC), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) levels were determined in the blood serum. En face and cross section lipid deposits were measured and quantified with Oil Red O staining. Hematoxylin and eosin (H&E) and Masson's trichrome staining were used to quantify atherosclerotic plaque size and collagen fiber content in aortic root sections. Reactive oxygen species (ROS) were detected in aortic root using dihydroethylenediamine (DHE) staining. Apoptosis rate was determined by TdT-mediated dUTP nick end labeling (TUNEL) staining. Immunofluorescence (IF) staining was used to detect the expression of the nuclear factor kappa-B (NF-κB) p65 and NOD-like receptor family pyrin domain containing 3 (NLRP3). To further investigate the protective effect of Sal B, we used TNF-α induced HUVECs inflammation model. We examined cell viability, lactate dehydrogenase (LDH) content, and ROS production. The transcription of NF-κB was evaluated by immunofluorescence. The mRNA levels of NLRP3, caspase-1, and IL-1β were detected by RT-PCR. Pyroptosis related proteins were detected by Western blot. RESULTS The change in the weight of the mice over time was an indication that Sal B had an effect on weight gain. IN VIVO STUDIES we were able to show that the serum lipids TC, TG and LDL-C were increased in the model group and that the treatment with Sal B reduced the levels of serum lipids. Histological staining showed that the LDLR-/- mice had a large amount of foam cell deposition accompanied by inflammatory cell infiltration and the formation of atherosclerotic plaques in theMOD group. The pathological abnormalities were significantly improved by Sal B treatment. ROS release and apoptosis were significantly increased after HFD in aortic root, which was attenuated by Sal B. IF results showed that the expression of NF-κB p65 and NLRP3 was significantly increased in the MOD group and significantly decreased in the Sal B group, suggesting that Sal B may act through the NF-κB/NLRP3 pathway. And in vitro studies: inflammatory damage of HUEVCs was induced by TNF-α, and Sal B treatmented significantly increased cell viability and reduced LDH release. It was also found that Sal B inhibited ROS level increase after TNF-α-induced HUEVCs. Activation of NF-κB p65 by TNF-α stimulation, NF-κB p65 is transferred to the nucleus. Sal B treatment could reverse this effect. RT-PCR and Western blot showed that Sal B affected NF-κB transcription and NLRP3 inflammasome activation and could significantly inhibit TNF-α-induced NLRP3 inflammasome activation. These results suggest that Sal B may participate in antiatherosclerotic and inflammatory responses through the NF-κB/NLRP3 pathway. CONCLUSIONS This study shows that Sal B ameliorates the development of AS lesions in HFD-induced LDLR-/- mice. Furthermore, under TNF-α conditions, Sal B reduced ROS release and reversed nuclear translocation of NF-κB, and inhibited atherosclerosis and inflammation by modulating the NF-κB/NLRP3 pathway.

Abstract
Ηypercholesterolemia/hyperlipidemia in conjunction with oxidative stress and inflammatory processes contribute synergistically to the pathogenesis of atherosclerosis. We hereby evaluated the antiatherosclerotic effect of the multi-target derivative 4-methyl-2-(10H-phenothiazin-3-yl)morpholin-2-ol hydrobromide 1 in apoE-/- mice; compound 1 is a potent antihyperlipidemic agent acting through Squalene Synthase inhibition, while it has exhibited an outstanding antioxidant and anti-inflammatory activity in various experimental animal models. The new analogue was evaluated in terms of its antiatherosclerotic/antioxidant effect in the ApoE-/- transgenic mouse model. Its toxicity profile was also assessed by measuring the levels of four sensitive indicators of liver toxicity. Prolonged administration of 1 in ApoE-/- mice fed with a western-type (wt) diet efficiently reduced the aortic atheromatic lesions, an effect that took place through a cholesterol lowering independent manner. In addition, 1 displayed a significant reduction not only of glucose but also of oxidative stress levels, while it did not cause any toxicity. To the best of our knowledge this is the first time that the antiatherosclerotic effect of a Squalene Synthase inhibitor is studied in this specific atherosclerosis mouse model. As a result, compound 1 may serve as a promising starting point towards developing new bioactive analogues against the onset and subsequent development of atherosclerosis.

Abstract
Presently, there are many drugs for the treatment of atherosclerosis (AS), among which lipid-lowering, anti-inflammatory, and antiproliferative drugs have been the most studied. These drugs have been shown to have inhibitory effects on the development of AS. Nanoparticles are suitable for AS treatment research due to their fine-tunable and modifiable properties. Compared with drug monotherapy, experimental results have proven that the effects of nanoparticle-encapsulated drugs are significantly enhanced. In addition to nanoparticles containing a single drug, there have been many studies on collaborative drug treatment, collaborative physical treatment (ultrasound, near-infrared lasers, and external magnetic field), and the integration of diagnosis and treatment. This review provides an introduction to the therapeutic effects of nanoparticles loaded with drugs to treat AS and summarizes their advantages, including increased targeting ability, sustained drug release, improved bioavailability, reduced toxicity, and inhibition of plaque and vascular stenosis.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 112:154694.

Abstract
BACKGROUND Atherosclerosis is the most prevalent cardiovascular disease and remains the major contributor to death and mortality globally. Salvianolic acid A (SalA) is a water-soluble phenolic acid that benefits atherosclerosis. However, the mechanisms of SalA protecting against atherosclerosis remain unclear. PURPOSE We aimed to determine whether SalA prevents atherosclerosis by modulating 3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) degradation via the ubiquitin-proteasomal pathway. METHODS The animal and cellular models of atherosclerosis were established by subjecting apolipoprotein E (ApoE) knockout mice to a high-fat diet (HFD) and exposing human umbilical vein endothelial cells (HUVECs) to oxidized low-density lipoprotein (ox-LDL), respectively. RESULTS Our results showed that similar to atorvastatin, SalA suppressed atherosclerotic plaque formation, improved serum lipid accumulation, and reduced cholesterol levels in HFD-fed ApoE-/- mice. Moreover, SalA protected HUVECs from ox-LDL-caused cell viability reduction and lipid accumulation. The mechanism study revealed that SalA reduced the production of proinflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6, and augmented the generation of the anti-inflammatory cytokine IL-10 in ApoE-/- mice and HUVECs, accompanied by increased HMGCR ubiquitination and degradation via translocation in renal carcinoma on chromosome 8 (Trc8), insulin-induced gene (Insig)1 and Insig2. Furthermore, the knockdown of Trc8 abolished the SalA-induced HMGCR degradation and anti-atherosclerosis activity. CONCLUSION SalA rescues atherosclerosis by inhibiting inflammation through the Trc8-regulated degradation of HMGCR. These findings underscore Trc8 as a potential target of atherosclerosis.

Abstract
In atherosclerosis, chronic inflammatory processes in local diseased areas may lead to the accumulation of reactive oxygen species (ROS). In this study, we devised a highly sensitive H2O2-scavenging nano-bionic system loaded with probucol (RPP-PU), to treat atherosclerosis more effectively. The RPP material had high sensitivity to H2O2, and the response sensitivity could be reduced from 40 to 10 μmol/L which was close to the lowest concentration of H2O2 levels of the pathological environment. RPP-PU delayed the release and prolonged the duration of PU in vivo. In Apolipoprotein E deficient (ApoE‒/‒) mice, RPP-PU effectively eliminated pathological ROS, reduced the level of lipids and related metabolic enzymes, and significantly decreased the area of vascular plaques and fibers. Our study demonstrated that the H2O2-scavenging nano-bionic system could scavenge the abundant ROS in the atherosclerosis lesion, thereby reducing the oxidative stress for treating atherosclerosis and thus achieve the therapeutic goals with atherosclerosis more desirably.

Synergistic Effect of Polydatin and Polygonatum sibiricum Polysaccharides in Combating Atherosclerosis via Suppressing TLR4-Mediated NF- κB Activation in ApoE-Deficient Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:3885153. [PMID: 35845572 PMCID: PMC9283052 DOI: 10.1155/2022/3885153] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 06/17/2022] [Indexed: 11/18/2022]
Abstract
Objective Atherosclerosis is a chronic inflammatory disease, which is closely related to hyperlipidemia, inflammatory responses, and oxidative stress. As natural products, polydatin (PD) and Polygonatum sibiricum polysaccharides (PSP) have remarkable pharmacological effects in anti-inflammatory, antioxidant stress, and lipid regulation. In this study, we sought to investigate whether the combination of polydatin and P. sibiricum polysaccharides play an anti-atherosclerotic role in alleviating inflammatory responses by inhibiting the toll-like receptor4 (TLR4)/myeloid differentiation factor88(MyD88)/nuclear factor-kappa B(NF-κB) signaling pathway. Methods Thirty-two ApoE-/- mice were fed with a high-fat diet (HFD) starting at the age of 8 weeks. Mice were randomly divided into four groups; (1) model group, (2) PD (100 mg/kg) + PSP (50 mg/kg) group, (3) TAK-242 (3 mg/kg) (TLR4 inhibitor) group, (4) PD (100 mg/kg) + PSP (50 mg/kg) + TAK-242 (3 mg/kg) group. Eight age-matched wild-type C57BL/6J mice fed an ordinary diet were used as a control group. Blood lipid levels were measured with an automatic biochemical analyzer. The lipid accumulation and histopathological changes in the aorta and liver were observed by Oil Red O and hematoxylin and eosin (H&E) staining, respectively. ELISA was performed to measure the serum levels of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1). Western blot analysis was performed to analyze the expression of key proteins in the TLR4/MyD88/NF-κB signaling pathway. Results Compared with the model group, the combination of PD and PSP significantly inhibit serum lipids (low-density lipoprotein cholesterol, total cholesterol, and triglyceride) and cell adhesion molecules (VCAM-1, ICAM-1). Oil Red O staining indicated that the combination of PD and PSP decrease lipid accumulation in the aorta and liver. Moreover, H&E staining suggested that the combination of PD and PSP alleviate aortic intimal hyperplasia, inflammatory cell infiltration, and hepatic steatosis. Finally, the combination of PD and PSP inhibit the expression of TLR4, MyD88, and the phosphorylation level of NF-κB p65 protein in the aorta. Conclusions Polydatin synergizes with P. sibiricum polysaccharides in preventing the development of atherosclerosis in ApoE-/- mice by inhibiting the TLR4/MyD88/NF-κB signaling pathway.

[PMID: 35929293 DOI: 10.1016/j.bioadv.2022.212775] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 03/07/2022] [Accepted: 03/21/2022] [Indexed: 05/27/2023]
Abstract
Atherosclerosis (AS), the formation of plaque lesions in the walls of arteries, causes many mortalities and morbidities worldwide. Currently, achieving site-specific delivery and controlled release at plaques is difficult. Herein, we implemented the strategy of constructing a bionic multifunctional nanoplatform (BM-NP) for targeting and improving plaques. BM-NPs were prepared based on probucol-loaded mesoporous polydopamine (MPDA) carriers and were coated with platelet membranes to impart bionic properties. In vitro experiments confirmed that BM-NPs, which respond to near-infrared (NIR) for drug release, remove reactive oxygen species (ROS), thereby reducing the level of oxidized low-density lipoprotein (ox-LDL) and ultimately helping to inhibit macrophage foaming. In vivo experiments proved that BM-NPs actively accumulated in plaques in the mouse right carotid artery (RCA) ligation model. During treatment, BM-NPs with NIR laser irradiation more effectively reduced the area of plaque deposition and slowed the thickening of the arterial wall intima. More importantly, BM-NPs showed the advantage of inhibiting the increase in triglyceride (TG) content in the body, and good biocompatibility. Hence, our research results indicate that intelligent BM-NPs can be used as a potential nanotherapy to precisely and synergistically improve AS.

Red blood cell biomimetic nanoparticle with anti-inflammatory, anti-oxidative and hypolipidemia effect ameliorated atherosclerosis therapy. NANOMEDICINE : NANOTECHNOLOGY, BIOLOGY, AND MEDICINE 2022; 41:102519. [PMID: 35038590 DOI: 10.1016/j.nano.2022.102519] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 12/07/2021] [Accepted: 12/29/2021] [Indexed: 12/30/2022]
Abstract
A main pathogenic factor of atherosclerosis is the local oxidative stress microenvironment. Probucol (PU) has anti-inflammatory, antioxidative and hypolipidemic effects, showing great potential to treat atherosclerosis. However, its low bioavailability limits its development. Herein, PU was encapsulated to form RP-PU with star-shaped polymers and red blood cell membranes. Star-shaped polymers show lower solution viscosity, a smaller hydrodynamic radius and a higher drug loading content than linear polymers. RP-PU had a good sustained-release effect and excellent biocompatibility. RP-PU can be efficiently internalized by cells to improve biodistribution. ApoE-/- mice were treated with RP-PU, and the contents of lipids and related metabolic enzymes were effectively reduced. The collagen fibers in the aortic root sections were reduced by RP-PU compared with control and PU. Moreover, RP-PU inhibited foam cell formation, decreased ICAM-1 and MCP-1 expression and delayed lesion formation. Consequently, RP-PU biomimetic nanoparticles can be developed as an anti-atherosclerotic nanotherapeutic.

Abstract
Objectives: Salvianolic acid B (Sal B) is the main effective water-soluble
component of Salvia miltiorrhiza. In this study, the anti-inflammatory
effect of Sal B was explored in high-fat-diet (HFD)-induced LDLR-/- mice and oxidized
low-density-lipoprotein (ox-LDL)-induced or lipopolysaccharide (LPS)-induced RAW264.7
cells. Methods: The LDLR-/- mice were randomly divided into four groups after
12 weeks of high-fat diet. Then, the mice were administrated with 0.9% saline or Sal B
(25 mg/kg) or Atorvastatin (1.3 mg/kg) for 12 weeks. RAW 264.7 cells were induced with
ox-LDL/LPS, or ox-LDL/LPS plus different concentrations of Sal B (1.25 μg/mL, 2.5 μg/mL,
5 μg/mL), or ox-LDL plus Sal B plus MAPKs activators. ELISA was used for detecting serum
lipid profiles and inflammatory cytokines, RT-qPCR used for gene expression, Oil Red O
used for plaque sizes, and immunofluorescence staining used for NF-κB p65 and TNF-α
production. Inflammation-related proteins and MAPKs pathways were detected by Western
Blot. Results: The results showed that Sal B decreased the levels of serum
lipids (TC, TG, and LDL-C), attenuated inflammatory cytokines, and improved lipid
accumulation in the aorta. Sal B also attenuated the elevation of inflammatory cytokines
induced by ox-LDL or LPS in RAW264.7 cells, and the phosphorylation of MAPKs/NF-κB
pathways in the aorta and RAW264.7 cells, resulting in a significant decrease in the
contents of p-JNK, p-ERK 1/2, p-P38, p-IκB, and p-NF-κB p65. Conclusions: Sal
B could exert anti-inflammatory effects on atherosclerosis via MAPKs/NF-κB signaling
pathways in vivo and in vitro.

Abstract
Background Carotid atherosclerosis (CAS) is a common disease which seriously threatens the health of senile patients. The studies have indicated that traditional Chinese medicine (TCM) may effectively improve the symptom of CAS, while the therapeutic effect of Huayu Tongmai decoction on CAS remains unclear. Thus, this study aimed to explore the correlation between traditional Chinese medicine Huayu Tongmai decoction intervention and prognosis indexes of patients with CAS. Methods Ninety CAS patients admitted to Zibo TCM-Integrated Hospital from September 2018 to September 2020 were selected as the research object and randomly divided into the control group and the observation group according to the male-female ratio of 1 : 1. Patients in the control group accepted the atorvastatin intervention, and on this basis, patients in the observation group were further intervened with TCM Huayu Tongmai decoction. Before and after treatment, patients' levels of total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) were measured by the enzyme photometric colorimetry; hypersensitive c-reactive protein (hs-CRP) levels were measured by the ELISA method; nitric oxide (NO) levels were measured by the nitrate reductase assay and endothelin-1 (ET-1) levels were measured by radioimmunoassay; and the right and left carotid internal diameter (CAD), intima-media thickness (IMT), and plaque volume were measured by carotid ultrasonography. Results The TC, TG, and LDL-C levels significantly decreased in patients compared to those before intervention; compared with the control group, patients who accepted Huayu Tongmai decoction combined with atorvastatin saw more significant improvement in their blood lipid indexes (P < 0.01); after intervention, patients' hs-CRP and ET-1 levels dropped significantly while the NO level rose remarkably, and between the two groups, the improvement in levels of hs-CRP, ET-1, and NO of patients in the observation group was significantly better (P < 0.01); it was concluded from the imaging diagnosis results that compared with using atorvastatin alone, the combined intervention could better improve patients' CAD, IMT, and plaque volume. Conclusion Huayu Tongmai decoction can effectively improve patients' blood lipid, reduce inflammatory response, enhance levels of relevant regulatory factors of CAS, and alleviate the symptoms.

Abstract
Most of the current non-pharmacological treatment strategies for atherosclerosis (AS) suffer from poor penetration into the plaque and only aim at a certain factor in its formation process, resulting in limited therapeutic effect. Herein, a kind of nanomotor with dual-mode propulsion is constructed, which is sensitive to higher reactive oxygen species (ROS) at the AS site and near-infrared (NIR) laser by the covalent binding and self-assembly of β-cyclodextrin (β-CD) and L-arginine (LA) with immobilization of Au nanoparticles. NIR laser irradiation can be used as a driving force and to ablate inflammatory macrophages through the photothermal effect. The nitric oxide (NO) released by the nanomotors can be used as another driving force and a therapeutic agent to promote endothelial repair in the plaque site. LA can eliminate ROS in the inflammatory site, and β-CD can promote the removal of cholesterol from foam cells. In particular, the two driving modes of nanomotors synergistically promote their aggregation and penetration in the plaque. This kind of nanomotor can regulate the microenvironment of AS in multiple ways, including combination therapy for endothelial repair, lipid clearance, and reducing ROS, which is expected to become a potential non-pharmacological strategy in the treatment of AS.

Abstract
Atherosclerosis, the major cause of cardiovascular disease, is a chronic inflammatory disease. The anti-inflammatory effect of certain polyphenols has been recognized. Active polyphenols were extracted from millet shells (MSPs), and their main components including 3-hydroxybenzylhydrazine, luteolin-3',7-diglucoside, N-acetyltyramine, p-coumaric acid, vanillin, sinapic acid, ferulic acid and isophorone exhibited the anti-atherosclerotic potential in vitro. To explore the anti-atherosclerotic activity of MSPs in vivo, a classic atherosclerosis model was constructed in ApoE-/- mice fed with a high-fat diet. The results showed that MSPs effectively inhibited the development of atherosclerotic plaques in the aorta and reduced the levels of lipopolysaccharide (LPS) and inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). A further study found that the expression of tight junction proteins (occludin, zona occludens-1 and claudin1) was obviously up-regulated in the MSPs-treated group at the mRNA and protein levels. Interestingly, MSPs significantly changed the structure of gut microbiota in ApoE-/- mice with a high-fat diet, which is characterized by the enriched Oscillospira and Ruminococcus, and the abridged Allobaculum at the genus level. Collectively, these results suggest that MSPs regulate the integrity of the gut barrier and the structure of the gut microbiota, ultimately inhibiting the development of atherosclerotic plaques. This study provides new insights into the potential cardiovascular protective effects induced by millet shell polyphenols.

Huotan Jiedu Tongluo Decoction Inhibits Balloon-Injury-Induced Carotid Artery Intimal Hyperplasia in the Rat through the PERK-eIF2 α-ATF4 Pathway and Autophagy Mediation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5536237. [PMID: 34335815 PMCID: PMC8318774 DOI: 10.1155/2021/5536237] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 07/07/2021] [Accepted: 07/10/2021] [Indexed: 11/18/2022]
Abstract
In-stent restenosis (ISR) is the main factor affecting the outcome of percutaneous coronary intervention (PCI), and its main pathological feature is neointimal hyperplasia. Huotan Jiedu Tongluo decoction (HTJDTLD) is an effective traditional Chinese medicine (TCM) prescription for the treatment of vascular stenosis diseases. However, the precise anti-ISR mechanism of HTJDTLD remains unclear. Here, we investigated whether HTJDTLD can inhibit the excessive activation of endoplasmic reticulum stress (ERS) and reduce the level of autophagy factors through regulating the PERK-eIF2α-ATF4 pathway, thereby inhibiting the proliferation of the intima of blood vessels damaged by balloon injury (BI) and preventing the occurrence of ISR. In this study, a 2F Fogarty balloon was used to establish a common carotid artery (CCA) BI model in male Sprague-Dawley rats. Then, HTJDTLD (16.33 g/kg/d) or atorvastatin (1.19 mg/kg/d) was administered by gavage. Four weeks later, hematoxylin-eosin (HE) and Masson staining of the injured CCA were performed to observe the histological changes in the CCA. Immunohistochemistry (IHC) was used to assess the proliferation and dedifferentiation of vascular smooth muscle cells (VSMCs) in the CCA. Western blotting and RT-PCR were used to measure the expression of ERS- and autophagy-related proteins and mRNAs in the CCA. The results indicated that HTJDTLD significantly alleviated BI-induced carotid artery intimal hyperplasia and fibrosis and reduced the neointimal area (NIA) and NIA/medial area (MA) ratio. In addition, HTJDTLD inhibited the proliferation and dedifferentiation of VSMCs, reduced the expression of proliferating cell nuclear antigen (PCNA), and increased the smooth-muscle-α-actin- (SMα-actin-) positive area. HTJDTLD also significantly reduced the expression of the ERS-related factors: GRP78, p-PERK/PERK, p-eIF2α/eIF2α, ATF4, and CHOP. In addition, the expression of the autophagy-related factors, Beclin1, LC3B, and ATG12, was significantly decreased. In addition, in vitro experiments showed that HTJDTLD inhibited the above-mentioned ERS signal molecules in human umbilical vein endothelial cells (HUVEC) and rat aortic smooth muscle cells (A7R5) induced by tunicamycin (TM) and played a crucial role in protecting cells from damage. HTJDTLD may be a very promising drug for the treatment of ISR.

Abstract
Background: Recent studies have demonstrated a key role of vascular smooth muscle cell (VSMC) dysfunction in atherosclerosis. Cyclin-dependent kinases 9 (CDK9), a potential biomarker of atherosclerosis, was significantly increased in coronary artery disease patient serum and played an important role in inflammatory diseases. This study was to explore the pharmacological role of CDK9 inhibition in attenuating atherosclerosis. Methods: A small-molecule CDK9 inhibitor, LDC000067, was utilized to treat the high fat diet (HFD)-fed ApoE-/- mice and human VSMCs. Results: The results showed that inflammation and phenotypic switching of VSMCs were observed in HFD-induced atherosclerosis in ApoE-/- mice, which were accompanied with increased CDK9 in the serum and atherosclerotic lesions where it colocalized with VSMCs. LDC000067 treatment significantly suppressed HFD-induced inflammation, proliferation and phenotypic switching of VSMCs, resulting in reduced atherosclerosis in the ApoE-/- mice, while had no effect on plasma lipids. Further in vitro studies confirmed that LDC000067 and siRNA-mediated CDK9 knockdown reversed ox-LDL-induced inflammation and phenotypic switching of VSMCs from a contractile phenotype to a synthetic phenotype via inhibiting NF-κB signaling pathway in human VSMCs. Conclusion: These results indicate that inhibition of CDK9 may be a novel therapeutic target for the prevention of atherosclerosis.

Abstract
Atherosclerosis (AS) is a major cause of cardiovascular diseases, but its effective theranostic measure remains challenging thus far. Macrophages contribute to AS progress in diverse ways such as producing cytokines and reactive oxygen species (ROS), foaming macrophages, and differentiating into pro-inflammatory macrophages. With the aim of constructing a facile and efficacious theranostic system for diagnosis and treatment of AS, a templated self-assembly approach was developed. This strategy involves using indole molecule (indocyanine green (ICG) or IR783) as a template to assemble with probucol (PB) to gain multifunctional nanoparticles (IPNPs or IRPNPs). IPNPs and IRPNPs both showed excellent physicochemical properties, which testified the generality of the indole molecular self-assembly strategy for PB delivery. Besides, the nanoparticles have superior pharmaceutical characteristics including preventing macrophages from differentiating, more efficiently internalizing in inflammatory macrophages, eliminating overproduced ROS, lowering the level of inflammation cytokines, and inhibiting foaming. More importantly, IPNPs displayed effective therapeutic effects in AS model mice when administered via intravenous (i.v.) route. In addition, IPNPs and IRPNPs accumulated more effectively than ICG and IR783 via i.v. injection in the lesion area, and the blood circulation time was extended beyond 24 h. More interestingly, we discovered that the fluorescence imaging ability of IR783 and IRPNPs was more excellent than ICG and IPNPs, respectively. Moreover, a long-term treatment with IPNPs or IRPNPs revealed an excellent safety profile in mice. Accordingly, this self-assembly strategy developed herein is a universal and promising way for the delivery of lipophilic drugs. This study also provides new insights into developing effective theranostic agents for AS.

Abstract
Objective Probucol is a cholesterol-lowering agent whose ability to prevent atherosclerosis is currently under study. Herein, we investigate the putative mechanism of probucol by observation of changes in cellular cholesterol efflux and lipid droplet morphology in macrophages. Results The inhibitory activity of probucol was assessed in non-foam or foam cell macrophages expressing ABCA1 generated by treatment with fetal calf serum (FCS) alone or in combination with acetylated LDL, respectively. Probucol inhibited cholesterol efflux to apolipoprotein A-I (apoA-I) by 31.5±0.1% in THP-1 non-foam cells and by 18.5±0.2% in foam cells. In probucol-treated non-foam THP-1 cells, nascent high density lipoprotein (nHDL) particles with a diameter < 7 nm were generated, while in probucol-treated THP-1 foam cells nHDL particles of > 7 nm in diameter containing cholesterol were produced. Foam cells also displayed a significant accumulation of free cholesterol at the plasma membrane, as measured by percent cholestenone formed. Intracellularly, there was a significant decrease in lipid droplet number and an increase in size in probucol-treated THP-1 foam cells when compared to non-treated cells. Conclusions We report for the first time that probucol is unable to completely inhibit cholesterol efflux in foam cells to the same extent as in non-foam cells. Indeed, functional nHDL is released from foam cells in the presence of probucol. This difference in inhibitory effect could potentially be explained by changes in the plasma membrane pool as well as intracellular cholesterol storage independently of ABCA1.

Abstract
Long noncoding RNAs (lncRNAs) play important roles in the development of vascular diseases. However, the effect of lncRNA NORAD on atherosclerosis remains unknown. This study aimed to investigate the effect NORAD on endothelial cell injury and atherosclerosis. Ox-LDL-treated human umbilical vein endothelial cells (HUVECs) and high-fat-diet (HFD)-fed ApoE−/− mice were used as in vitro and in vivo models. Results showed that NORAD-knockdown induced cell cycle arrest in G0/G1 phase, aggravated ox-LDL-induced cell viability reduction, cell apoptosis, and cell senescence along with the increased expression of Bax, P53, P21 and cleaved caspase-3 and the decreased expression of Bcl-2. The effect of NORAD on cell viability was further verified via NORAD-overexpression. NORAD- knockdown increased ox-LDL-induced reactive oxygen species, malondialdehyde, p-IKBα expression levels and NF-κB nuclear translocation. Proinflammatory molecules ICAM, VCAM, and IL-8 were also increased by NORAD- knockdown. Additionally, we identified the strong interaction of NORAD and IL-8 transcription repressor SFPQ in HUVECs. In ApoE−/− mice, NORAD-knockdown increased the lipid disorder and atherosclerotic lesions. The results have suggested that lncRNA NORAD attenuates endothelial cell senescence, endothelial cell apoptosis, and atherosclerosis via NF-κB and p53–p21 signaling pathways and IL-8, in which NORAD-mediated effect on IL-8 might through the direct interaction with SFPQ.

Abstract
Atherosclerosis is one of the main causes of cardiovascular diseases. Our previous study indicated that a type of peroxidase derived from foxtail millet bran (FMBP) had prominent antitumor activities. In the present study, we found that FMBP had potential antiatherosclerosis effects. The results showed that FMBP treatment strongly suppressed lipid phagocytosis in both HASMCs and THP-1 cells by 52% and 49%, respectively. Further, FMBP significantly inhibited HASMCs migration by promoting transformation of HASMCs from synthetic to contractile, leading to the decrease of lipid phagocytosis. Simultaneously, FMBP repressed lipid uptake by reducing the expression of CD36 in THP-1 cells. In addition, FMBP reduced the secretion of inflammatory factor IL-1β by inhibiting the expression of STAT3 in THP-1 cells. Interestingly, FMBP also had the same effects in models of atherosclerosis constructed with ApoE-/- mice, including decreased aortic lesion area, repressed aortic sinus CD36 and STAT3 expression, and elevated serum HDL-C concentration. Collectively, these results indicate that FMBP has great potential in preventing the development of atherosclerosis.

Abstract
CXC chemokine ligand 12 (CXCL12) is a specific chemokine ligand and plays a significant role in cell chemotaxis. Upon binding to CXC chemokine receptor 4 (CXCR4) or CXCR7, CXCL12 can activate different signaling cascades to regulate cell proliferation, migration, and metabolism. CXCL12 exerts a pro-atherogenic action by aggravating multiple pathogenesis of atherogenesis, including dyslipidemia, inflammation, neointima hyperplasia, angiogenesis, and insulin resistance. Serum CXCL12 levels are also markedly increased in patients with atherosclerosis-associated disease. The present review focuses on recent advances in CXCL12 research in the pathogenesis of atherosclerosis together with its clinical values. This may provide insight into potential novel therapies for atherosclerosis.
