Abstract
BACKGROUND As a risk factor of cardiovascular diseases, homocysteine can be effectively lowered by folate. However, the associations of folate and homocysteine levels with the prognosis of ischemic stroke remained unclear. METHODS AND RESULTS A total of 3530 patients with ischemic stroke were included. Serum folate and homocysteine levels were measured at admission. The primary outcome was composite of death and major disability (modified Rankin Scale score≥3) at 3 months after stroke onset. Univariate and multivariate logistic regression models were used. The mediation effect of homocysteine was examined. During follow-up, 1056 participants developed the primary outcome. In the univariate model, participants in the highest quartile of folate had a 29% (95% CI, 0.58-0.87) decreased risk of primary outcome compared with those in the lowest quartile. After multivariate adjustment, the odds ratio associated with the highest quartile of folate was 0.58 (95% CI, 0.46-0.73) for primary outcome. In contrast, participants in the highest quartile of homocysteine had a 52% (95% CI, 1.24-1.98) increased risk of primary outcome compared with those in the lowest quartile. After multivariate adjustment, the odds ratio associated with highest quartile of homocysteine was 1.57 (95% CI, 1.24-1.98) for primary outcome. In addition, 25.5% of the observed associations between folate and primary outcome was mediated through homocysteine (P=0.012). CONCLUSIONS High folate levels were associated with low risks of death and major disability among Chinese patients with ischemic stroke, and homocysteine partially mediated the observed potential beneficial role of folate.

Adenosine kinase inhibition protects mice from abdominal aortic aneurysm via epigenetic modulation of VSMC inflammation. Cardiovasc Res 2024; 120:1202-1217.

Abstract
AIMS Abdominal aortic aneurysm (AAA) is a common, serious vascular disease with no effective pharmacological treatment. The nucleoside adenosine plays an important role in modulating vascular homeostasis, which prompted us to determine whether adenosine kinase (ADK), an adenosine metabolizing enzyme, modulates AAA formation via control of the intracellular adenosine level, and to investigate the underlying mechanisms. METHODS AND RESULTS We used a combination of genetic and pharmacological approaches in murine models of AAA induced by calcium chloride (CaCl2) application or angiotensin II (Ang II) infusion to study the role of ADK in the development of AAA. In vitro functional assays were performed by knocking down ADK with adenovirus-short hairpin RNA in human vascular smooth muscle cells (VSMCs), and the molecular mechanisms underlying ADK function were investigated using RNA-sequencing, isotope tracing, and chromatin immunoprecipitation quantitative polymerase chain reaction (ChIP-qPCR). The heterozygous deficiency of ADK protected mice from CaCl2- and Ang II-induced AAA formation. Moreover, specific knockout of ADK in VSMCs prevented Ang II-induced AAA formation, as evidenced by reduced aortic extracellular elastin fragmentation, neovascularization, and aortic inflammation. Mechanistically, ADK knockdown in VSMCs markedly suppressed the expression of inflammatory genes associated with AAA formation, and these effects were independent of adenosine receptors. The metabolic flux and ChIP-qPCR results showed that ADK knockdown in VSMCs decreased S-adenosylmethionine (SAM)-dependent transmethylation, thereby reducing H3K4me3 binding to the promoter regions of the genes that are associated with inflammation, angiogenesis, and extracellular elastin fragmentation. Furthermore, the ADK inhibitor ABT702 protected mice from CaCl2-induced aortic inflammation, extracellular elastin fragmentation, and AAA formation. CONCLUSION Our findings reveal a novel role for ADK inhibition in attenuating AAA via epigenetic modulation of key inflammatory genes linked to AAA pathogenesis.

Abstract
Abdominal Aortic Aneurysm (AAA) is a disease characterized by localized dilation of the abdominal aorta, involving multiple factors in its occurrence and development, ultimately leading to vessel rupture and severe bleeding. AAA has a high mortality rate, and there is a lack of targeted therapeutic drugs. Epigenetic regulation plays a crucial role in AAA, and the treatment of AAA in the epigenetic field may involve a series of related genes and pathways. Abnormal expression of these genes may be a key factor in the occurrence of the disease and could potentially serve as promising therapeutic targets. Understanding the epigenetic regulation of AAA is of significant importance in revealing the mechanisms underlying the disease and identifying new therapeutic targets. This knowledge can contribute to offering AAA patients better clinical treatment options beyond surgery. This review systematically explores various aspects of epigenetic regulation in AAA, including DNA methylation, histone modification, non-coding RNA, and RNA modification. The analysis of the roles of these regulatory mechanisms, along with the identification of relevant genes and pathways associated with AAA, is discussed comprehensively. Additionally, a comprehensive discussion is provided on existing treatment strategies and prospects for epigenetics-based treatments, offering insights for future clinical interventions.

Abstract
Abdominal aortic aneurysm (AAA) is a fatal cardiovascular disorder with high mortality and morbidity rates. To date, no drug has shown to significantly alleviate the risk of AAA. Previous studies have indicated that hyperhomocysteinemia (HHcy) significantly increases the incidence of AAA by disrupting endothelial cell homeostasis; however, the potential molecular mechanisms require clarification. Herein, we aimed to integrate transcriptomics analysis and molecular biology experiments to explore the potential molecular targets by which HHcy may increase the incidence of AAA. We integrated two AAA data profiles (GSE57691 and GSE7084) based on previously published microarray ribonucleic acid sequencing (RNAseq) data from the GEO database. Additionally, 500 μM homocysteine-treated human aorta endothelium cells microarray dataset (GSE175748) was downloaded and processed. Subsequently, single-cell RNA-seq profiles of the aortic aneurysms (GSE155468) were downloaded, scaled, and processed for further analysis. The microarray profiles analysis demonstrated that the Ras association domain family member 2 (RASSF2) and interleukin (IL)-1β are potentially the target genes involved in the HHcy-mediated aggravation of AAA formation. Single-cell RNAseq analysis revealed that RASSF2 might impair endothelial cell function by increasing inflammatory cell infiltration to participate in AAA formation. Finally, we conducted reverse transcription quantitative polymerase chain reaction and immunofluorescence analysis to validate the up-regulated mRNA expression of RASSF2 (p = 0.008) and IL-1β (p = 0.002) in AAA tissue compared to control tissue. Immunofluorescence staining revealed overexpression of RASSF2 protein in AAA tissue sections compared to control tissue (p = 0.037). Co-localization of RASSF2 and the aortic endothelium cell marker, CD31, was observed in tissue sections, indicating the potential involvement of RASSF2 in aortic endothelial cells. To summarise, our preliminary study revealed that HHcy may worsen AAA formation by up-regulating the expression of RASSF2 and IL-1β in aortic endothelium cells.

Oxidative stress-related genetic variation and antioxidant vitamin intake in intact and ruptured abdominal aortic aneurysm: a Swedish population-based retrospective cohort study.

Abstract
AIMS The aim of this study is to investigate how genetic variations in genes related to oxidative stress, intake of antioxidant vitamins, and any potential interactions between these factors affect the incidence of intact abdominal aortic aneurysm (AAA) and its rupture (rAAA), accounting for sex differences where possible. METHODS AND RESULTS The present retrospective cohort study (n = 25 252) uses baseline single-nucleotide polymorphisms (SNPs) and total antioxidant vitamin intake data from the large population-based, Malmö Diet and Cancer Study. Cumulative incidence of intact AAA was 1.6% and of rAAA 0.3% after a median follow-up of 24.3 years. A variant in NOX3 (rs3749930) was associated with higher rAAA risk in males [adjusted hazard ratio (aHR): 2.49; 95% confidence interval (CI): 1.36-4.35] and the overall population (aHR: 1.88; 95% CI: 1.05-3.37). Higher intakes of antioxidant vitamins, riboflavin, and folate were associated with 20% and 19% reduced intact AAA incidence, respectively. Interestingly, the inverse associations between riboflavin and vitamin D intake with intact AAA incidence were stronger in the individuals carrying the NOX3 variant as compared with the wild-type recessive genotype, i.e. by 60% and 66%, respectively (P for interaction < 0.05). Higher riboflavin intake was associated with a 33% male-specific intact AAA risk reduction, while higher intake of vitamin B12 intake was associated with 55% female-specific intact AAA risk increase; both these associations were significantly modified by sex (P for interaction < 0.05). CONCLUSIONS Our findings highlight the role of oxidative stress genetic variations and antioxidant vitamin intake in AAA. Although a low AAA/rAAA sample size limited some analyses, especially in females, our findings highlight the need for future randomized controlled trials and mechanistic studies, to explore the potential benefits of antioxidant vitamins while accounting for genetic and sex differences.

Abstract
Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease characterized by the expansion of the aortic wall. One of the most significant features is the infiltration of macrophages in the adventitia, which drives vasculature remodeling. The role of macrophage-derived interferon regulatory factor 5 (IRF5) in macrophage infiltration and AAA formation remains unknown. RNA sequencing of AAA adventitia identified Irf5 as the top significantly increased transcription factor that is predominantly expressed in macrophages. Global and myeloid cell-specific deficiency of Irf5 reduced AAA progression, with a marked reduction in macrophage infiltration. Further cellular investigations indicated that IRF5 promotes macrophage migration by direct regulation of downstream phosphoinositide 3-kinase γ (PI3Kγ, Pik3cg). Pik3cg ablation hindered AAA progression, and myeloid cell-specific salvage of Pik3cg restored AAA progression and macrophage infiltration derived from Irf5 deficiency. Finally, we found that IRF5 and PI3Kγ expression in the adventitia is significantly increased in patients with AAA. These findings reveal that the IRF5-dependent regulation of PI3Kγ is essential for AAA formation.

Abstract
RATIONALE AND OBJECTIVES The pathophysiology of fusiform intracranial aneurysm (FIA) involves inflammatory processes, and homocysteine plays a role in the inflammatory processes in the vessel wall. Moreover, aneurysm wall enhancement (AWE) has emerged as a new imaging biomarker of aneurysm wall inflammatory pathologies. To investigate the pathophysiological mechanisms of aneurysm wall inflammation and FIA instability, we aimed to determine the associations between the homocysteine concentration, AWE, and FIAs' related symptoms. MATERIALS AND METHODS We retrospectively reviewed the data of 53 patients with FIA who underwent both high-resolution magnetic resonance imaging and serum homocysteine concentration measurement. FIAs' related symptoms were defined as ischemic stroke or transient ischemic attack, cranial nerve compression, brainstem compression, and acute headache. The contrast ratio of the signal intensity of the aneurysm wall to the pituitary stalk (CRstalk) was used to indicate AWE. Multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were performed to determine how well the independent factors could predict FIAs' related symptoms. Predictors of CRstalk were also investigated. Spearman's correlation coefficient was used to identify the potential associations between these predictors. RESULTS Fifty-three patients were included, of whom 23 (43.4%) presented with FIAs' related symptoms. After adjusting for baseline differences in the multivariate logistic regression analysis, the CRstalk (odds ratio [OR]=3.207, P = .023) and homocysteine concentration (OR=1.344, P = .015) independently predicted FIAs' related symptoms. The CRstalk was able to differentiate between FIAs with and without symptoms (area under the ROC curve [AUC]=0.805), with an optimal cutoff value of 0.76. The homocysteine concentration could also differentiate between FIAs with and without symptoms (AUC=0.788), with an optimal cutoff value of 13.13. The combination of the CRstalk and homocysteine concentration had a better ability to identify symptomatic FIAs (AUC=0.857). Male sex (OR=0.536, P = .018), FIAs' related symptoms (OR=1.292, P = .038), and homocysteine concentration (OR=1.254, P = .045) independently predicted the CRstalk. CONCLUSION A higher serum homocysteine concentration and greater AWE indicate FIA instability. Serum homocysteine concentration may be a useful biomarker of FIA instability; however, this needs to be verified in future studies.

Abstract
OBJECTIVES To investigate the actions of amlodipine-folic acid (amlodipine-FA) preparation on hypertension and cardiovascular in renal hypertensive rats with hyperhomocysteinemia (HHcy), so as to provide experimental basis for clinical research of amlodipine folic acid tablets. METHODS Rats model of renal hypertension with HHcy were established. The rats were randomly divided into groups of model, amlodipine, folic acid (FA) and amlodipine-FA of various dosages. Normal rats were used as normal control group. Blood pressure, Hcy as well as plasma NO, ET-1 and hemodynamics were assayed. Histological alterations of heart and abdominal aorta were also examined. RESULTS Compared with the normal group, blood pressure, plasma Hcy, and NO of the rats in model group were significantly increased, while the plasma ET-1 was decreased. Compared with the normal group, the animals in the model group had reduced cardiac function, thickened wall of the aorta and narrowed lumen. In FA group and amlodipine group, the rat plasma NO was increased while ET-1 was decreased, the protective effect of amlodipine-FA group on endothelial cells was further enhanced. In amlodipine group, the rat hemodynamics (LVSP, LVEDP and ±dp/dtmax, et al.) and vascular damage were significantly reduced, while in amlodipine-FA group, the heart function were further improved, and myocardial and vascular hypertrophy were significantly reduced. CONCLUSIONS As compared to amlodipine alone, amlodipine -FA can lower both blood pressure and plasma Hcy, significantly enhancing vascular endothelial function to protect the heart and blood vessel in renal hypertensive rats with HHcy.

Abstract
Aortic dissection (AD) is a cardiovascular disease that seriously endangers the lives of patients. The mortality rate of this disease is high, and the incidence is increasing annually, but the pathogenesis of AD is complicated. In recent years, an increasing number of studies have shown that immune cell infiltration in the media and adventitia of the aorta is a novel hallmark of AD. These cells contribute to changes in the immune microenvironment, which can affect their own metabolism and that of parenchymal cells in the aortic wall, which are essential factors that induce degeneration and remodeling of the vascular wall and play important roles in the formation and development of AD. Accordingly, this review focuses on the independent and interactive roles of immunity and metabolism in AD to provide further insights into the pathogenesis, novel ideas for diagnosis and new strategies for treatment or early prevention of AD.

[PMID: 37765020 PMCID: PMC10534320 DOI: 10.3390/ph16091212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 08/18/2023] [Accepted: 08/22/2023] [Indexed: 09/29/2023] Open
Abstract
Doxorubicin, a widely used chemotherapeutic drug in clinical oncology, causes a series of cardiac side effects referred to as doxorubicin-induced cardiotoxicity. Hyperhomocysteinaemia is an independent risk factor for multiple cardiovascular diseases. However, whether hyperhomocysteinaemia contributes to doxorubicin-induced cardiotoxicity is currently unknown. In this study, we explored the pathogenic effects of hyperhomocysteinaemia induced by dietary methionine supplementation (2% wt/wt in rodent chow) in a mouse model of doxorubicin-induced cardiotoxicity. Our data showed that methionine supplementation doubled serum homocysteine levels, inducing mild hyperhomocysteinaemia. Doxorubicin at a cumulative dosage of 25 mg/kg body weight led to significant weight loss and severe cardiac dysfunction, which were further exacerbated by methionine-induced mild hyperhomocysteinaemia. Doxorubicin-induced cardiac atrophy, cytoplasmic vacuolisation, myofibrillar disarray and loss, as well as cardiac fibrosis, were also exacerbated by methionine-induced mild hyperhomocysteinaemia. Additional folic acid supplementation (0.006% wt/wt) prevented methionine-induced hyperhomocysteinaemia and inhibited hyperhomocysteinaemia-aggravated cardiac dysfunction and cardiomyopathy. In particular, hyperhomocysteinaemia increased both serum and cardiac oxidative stress, which could all be inhibited by folic acid supplementation. Therefore, we demonstrated for the first time that hyperhomocysteinaemia could exacerbate doxorubicin-induced cardiotoxicity in mice, and the pathogenic effects of hyperhomocysteinaemia might at least partially correlate with increased oxidative stress and could be prevented by folic acid supplementation. Our study provides preliminary experimental evidence for the assessment of hyperhomocysteinaemia as a potential risk factor for chemotherapy-induced cardiotoxicity in cancer patients.

Abstract
Hyperhomocysteinemia (HHcy) worsens cardiovascular outcomes by impairing vascular function and promoting chronic inflammation via release of danger-associated molecular patterns, such as high-mobility group box-1 (HMGB-1). Elevated levels of HMGB-1 have recently been reported in patients with HHcy. Therefore, targeting HMGB-1 may be a potential therapy to improve HHcy-induced cardiovascular pathologies. This study aimed to further elucidate HMGB-1's role during acute HHcy and HHcy-induced atherogenesis and to determine if inhibiting HMGB-1 with glycyrrhizic acid (Glyz) improved vascular function. Male New Zealand White rabbits (n = 25) were placed on either a standard control chow (CD; n = 15) or atherogenic diet (AD; n = 10) for 4 weeks. Rabbit serum and Krebs taken from organ bath studies were collected to quantify HMGB-1 levels. Isometric tension analysis was performed on abdominal aorta (AA) rings from CD and AD rabbits. Rings were incubated with homocysteine (Hcy) [3 mM] for 60 min to induce acute HHcy or rhHMGB-1 [100 nM]. Vascular function was assessed by relaxation to cumulative doses of acetylcholine. Markers of vascular dysfunction and inflammation were quantified in the endothelium, media, and adventitia of AA rings. HMGB-1 was significantly upregulated in serum (p < 0.0001) and Krebs (p < 0.0001) after Hcy exposure or an AD. Incubation with Hcy (p < 0.0001) or rhHMGB-1 (p < 0.0001) and an AD (p < 0.0001) significantly reduced relaxation to acetylcholine, which was markedly improved by Glyz. HMGB-1 expression was elevated (p < 0.0001) after Hcy exposure and AD (p < 0.0001) and was normalized after Glyz treatment. Moreover, markers of vascular function, cell stress and inflammation were also reduced after Glyz. These results demonstrate that HMGB-1 has a central role during HHcy-induced vascular dysfunction and inhibiting it with Glyz could be a potential treatment option for cardiovascular diseases.

Abstract
Our group previously reported that hirudin ameliorated diabetic nephropathy (DN) in streptozotocin (STZ)-injected rats, but the mechanism remained largely unknown. Therefore, we further explored its possible mechanism. We subcutaneously injected 5 U hirudin into STZ-induced WT mice or Gasdermin D (Gsdmd)-/- (KO) mice daily for 12 weeks, respectively, and evaluated their kidney injury. Next, glomerular endothelial cells (GECs), renal tubular epithelial cells (RTECs), and bone-marrow-derived macrophages (BMDMs) were isolated from WT mice and treated with hirudin in the presence of high glucose/lipopolysaccharides and ATP to measure the release of interleukin-18 and interleukin-1β. Kidney injury induced by STZ injection was significantly ameliorated by hirudin through inhibiting Gsdmd-mediated pyroptosis in the mice, not Caspase 1-mediated apoptosis. Meanwhile, hirudin also suppressed pyroptosis in primary GECs, RTECs, and BMDMs in vitro. Moreover, the deletion of Gsdmd reduced pyroptosis and kidney injury both in vivo and in vitro. We also found that hirudin regulated the expression of Gsdmd by inhibiting interferon regulatory factor 2 (Irf2). Hirudin ameliorated Gsdmd-mediated pyroptosis by inhibiting irf2, leading to the improvement of kidney injury. Therefore, hirudin might serve as a potential therapeutic strategy to treat DN.

Abstract
INTRODUCTION Diabetic nephropathy (DN) is a common complication in diabetic patients. Chemerin, a novel adipokine, has been associated with renal damage in DN. The chemerin chemokine-like receptor 1 (CMKLR1) has been reported to participate in DN. In this study, we aimed to investigate the effect of a CMKLR1 antagonist, 2-(anaphthoyl)ethyltrimethylammonium iodide (α-NETA), on DN. METHODS To induce diabetes, 8-week-old male C57BL/6J mice were given a single intraperitoneal injection of 65 mg/kg streptozotocin (STZ). Diabetic mice were randomly assigned to receive daily doses of 0, 5, or 10 mg/kg α-NETA for 4 weeks. RESULTS α-NETA dose-dependently induced body weight and reduced fasting blood glucose levels in STZ-induced diabetic mice. Furthermore, α-NETA significantly reduced the expressions of renal injury markers, including serum creatinine, kidney weight/body weight, urine volume, total proteins, and albumin in the urine, and increased creatinine clearance. Periodic acid-Schiff staining also indicated that α-NETA could effectively ameliorate renal injuries in DN mice. In addition, α-NETA inhibited renal inflammation and the expressions of chemerin and CMKLR1 in mice with DN. CONCLUSION In summary, our findings suggested that α-NETA has beneficial effects on the management of DN. Specifically, α-NETA effectively ameliorated renal damage and inflammation in a dose-dependent manner in mice with DN. Thus, targeting the chemerin and CMKLR1 axis with α-NETA may be a promising therapeutic strategy for the treatment of DN.

Abstract
Osteomyelitis is the infection and destruction of bone. Until now, there is no universal protocol for its treatment. Receptor-interacting serine/threonine-protein kinase 2 (RIPK2) was implicated in the development of osteomyelitis. However, its detailed mechanism remains unknown. 6-8 weeks old wild-type or Pellino E3 Ubiquitin Protein Ligase Family Member 3 (Peli3) deficiency mice were injected with S. aureus to induce osteomyelitis. RAW264.7 cells or bone marrow-derived macrophages (BMDMs) isolated from mice, were treated with lipopolysaccharides (LPS). Knocking down Peli3 in RAW264.7 cells increased the expressions of inflammatory cytokines after the stimulation of LPS, including interleukin-1β, interleukin-6 and tumor necrosis factor-α. Inflammation was also activated in S. aureus-induced Peli3 deficiency mice. Moreover, Peli3 deficiency mice also displayed more severe symptoms of osteomyelitis in S. aureus-infected mice. Moreover, Peli3 targeted and degraded RIPK2 through K48-linked ubiquitination. Peli3 negatively modulates osteomyelitis by degrading RIPK2. Our data further expand current understanding of RIPK2 on osteomyelitis, which suggests that RIPK2 might serve as novel therapeutic target for treating osteomyelitis.

Abstract
BACKGROUND Diabetic retinopathy is a common and specific microvascular complication of diabetes, which is also the leading cause of preventable blindness. Therefore, we aimed to find a promising therapeutic strategy for diabetic retinopathy. METHODS To investigate the role of toll-like receptor 4 (TLR4) in the diabetic retinopathy, we injected streptozotocin (STZ) into wild-type (wt) and TLR4 knock-out mice to induce diabetes. RESULTS While STZ induced diabetes both in wt and TLR4-/- mice, deletion of TLR4 in diabetic mice significantly improved diabetic retinopathy compared to diabetic wt mice, as judged by the enhanced thickness of retinal tissue. Furthermore, TLR4-dependent NF-κB pathway, inflammatory cytokine release and the expressions of vascular endothelial growth factor (VEGF) and glial fibrillary acidic protein (GFAP), which were all remarkably stimulated in STZ-injected wt mice, were inhibited in STZ-injected TLR4-/- mice. CONCLUSION TLR4 could serve as an independent target for treating diabetic retinopathy.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common digestive system cancers with high mortality rates worldwide. The main ingredients in Mu Ji Fang Granules (MJF) are alkaloids, flavonoids, and polysaccharides. MJF has been used in the clinical treatment of hepatitis, cirrhosis and HCC for more than 30 years. Few previous studies have focused on the mechanism of MJF on tumor immu-nology in the treatment of HCC.
AIM To explore the mechanism of action of MJF on tumor immunology in the treatment of HCC.
METHODS The absorbable ingredients of MJF were identified using Molecule Network related to High Performance Liquid Chromatography-Electron Spray Ionization-Time of Flight- Mass Spectrometry, and hub potential anti-HCC targets were screened using network pharmacology and pathway enrichment analysis. Forty male mice were randomly divided into the Blank, Model, and MJF groups (1.8, 5.4, and 10.8 g/kg/d) following 7 d of oral administration. Average body weight gain, spleen and thymus indices were calculated, tumor tissues were stained with hematoxylin and eosin, and Interferon gamma (IFN-γ), Tumor necrosis factor α (TNF-α), Interleukin-2, aspartate aminotransferase, alanine aminotransferase, alpha-fetoprotein (AFP), Fas, and FasL were measured by Enzyme-linked Immunosorbent Assay. Relevant mRNA expression of Bax and Bcl2 was evaluated by Real Time Quantitative PCR (RT-qPCR) and protein expression of Transforming growth factor β1 (TGF-β1) and Mothers against decapentaplegic homolog (SMAD) 4 was assessed by Western blotting. The HepG2 cell line was treated with 10 mg/mL, 20 mg/mL, 30 mg/mL, 40 mg/mL of MJF, and another 3 groups were treated with TGF-β1 inhibitor (LY364947) and different doses of MJF. Relevant mRNA expression of TNF-α, IFN-γ, Bax and Bcl2 was evaluated by RT-qPCR and protein expression of TGF-β1, SMAD2, p-SMAD2, SMAD4, and SMAD7 was assessed by Western blotting.
RESULTS It was shown that MJF improved body weight gain and tumor inhibition rate in H22 tumor-bearing mice, protected immune organs and liver function, reduced the HCC indicator AFP, affected immunity and apoptosis, and up-regulated the TGF-β1/SMAD signaling pathway, by increasing the relative expression of TGF-β1, SMAD2, p-SMAD2 and SMAD4 and decreasing SMAD7, reducing immune factors TNF-α and IFN-γ, decreasing apoptosis cytokines Fas, FasL and Bcl2/Bax, and inhibiting the effect of LY364947 in HepG2 cells.
CONCLUSION MJF inhibits HCC by activating the TGF-β1/SMAD signaling pathway, and affecting immune and apoptotic cytokines, which may be due to MJF adjusting immune escape and apoptosis.

Abstract
Thromboembolic manifestations are relatively frequent in patients with intermediate/severe hyperhomocysteinemia (>30 µmol/L) related to inherited disorders and deficiencies in vitamin B12 and folate. In contrast, moderate hyperhomocysteinemia (15-30 µmol/L) is a modest predictor of cardiovascular risk. The recognition of homocysteine as a cardiovascular risk factor has been challenged by some but not all randomized clinical trials. We reviewed the main data of this controversy and formulated conclusions to be translated in clinical practice.Homocysteine-lowering trials have been performed in cardiovascular subjects with moderate but not intermediate/severe hyperhomocysteinemia despite the dose-effect risk association. The first meta-analyses found no benefit and led cardiology societies not recommending homocysteine in the assessment of cardiovascular risk. This guideline challenged the need to diagnose and treat the nutritional and genetic causes of intermediate/major hyperhomocysteinemia and was not revised when larger meta-analyses concluded to a reduced risk of stroke. In a recent observational study, 84% of consecutive cardiovascular patients assessed for homocysteine had intermediate or major hyperhomocysteinemia, which was properly assessed in only half of the cases and related to B12 and/or folate deficiency and Addison/Biermer disease in 55% of these cases.In conclusion, revisiting observational studies and clinical trials suggests that cardiovascular patients should be screened for hyperhomocysteinemia, when no other risk factor is found. Patients with intermediate/major hyperhomocysteinemia should be properly assessed and treated for B vitamin deficiencies and inherited disorders according to current guidelines. Further trials are needed to assess the effect of lowering homocysteine according to hyperhomocysteinemia categories at baseline.

Abstract
INTRODUCTION Diabetic nephropathy (DN) is a long-term loss of renal function occurring in the diabetic patients, leading to 5 million deaths in 2015, and this number is dramatically growing annually. Due to unsatisfied outcome of current treatment, there is urgent need to develop more effective therapeutic drugs for DN. METHODS Approximately 150 kinds of natural small molecule drugs that have been used on the market or in the clinical trials in the presence of high glucose were tested individually on the same batch of human renal glomerular endothelial cells (GECs) and human kidney 2 (HK-2) cells with triplicated wells by using a robotic pipetting workstation to screen for the potential drug candidate. Cell viability and oxidative stress were examined in the GECs and HK-2 cells. DN mouse model was established and treated with 25 mg/kg xanthohumol. RESULTS By measuring cell viability, xanthohumol was selected as our predicted drug candidate for DN because it could mostly protect renal cells from high glucose with about 90% survived GECs and HK-2 cells, about 2.12- and 2.37-fold increase compared to glucose group which was with 42.78% and 37.69% survived GECs and HK-2 cells, respectively. Then, xanthohumol inhibited high glucose-induced oxidative stress through nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway in vitro. Moreover, xanthohumol (25 mg/kg) significantly decreased the levels of serum creatinine, blood urea nitrogen, urea protein, and kidney weight/body weight ratio in DN mice. In addition, the increase of reactive oxygen species production and the decrease of superoxide dismutase and catalase activities in DN mice were partially reversed by xanthohumol. mRNA levels of Nrf2, Hmox1, and Nqol genes were all decreased by xanthohumol DN mice. CONCLUSION Xanthohumol could ameliorate DN-related impairments via Nrf2 signaling pathway, which might serve as a promising drug candidate for treatment of DN.

Abstract
Diabetic retinopathy is one of the most common microvascular complications of diabetes. Inhibition of histone deacetylase 3 (Hdac3) was proven to be a successful way to ameliorate central nervous system injury and vision problem in a glaucoma mouse model. However, its role in diabetic retinopathy remains largely unknown. Eight-week-old C57BL/6J mice were intraperitoneally injected with 50 mg of streptozotocin for 5 consecutive days to induce diabetes. After 1 wk, diabetic mice were selected and treated with Hdac3 inhibitor RGFP966 once every 3 days for 12 consecutive weeks. It was found that RGFP966 could decrease the mRNA and protein expression of Hdac3. It significantly increased diabetic retinopathy-reduced retinal thickness without affecting fasting blood glucose. It also decreased diabetic retinopathy-activated oxidative stress and cell apoptosis. Moreover, diabetic retinopathy mice displayed an increased expression of vascular endothelial growth factor and a decreased expression of glial fibrillary acidic protein, both of which were partially restored by RGFP966 treatment. Mechanically, RGFP966 decreased the expression of NADPH oxidase 2 (Nox2) whereas it increased the expression of superoxide dismutase 2 (Sod2) in diabetic retinopathy mice. In conclusion, RGFP966 significantly reduces oxidative stress, inflammation, and cell apoptosis in the retina of streptozotocin-induced diabetic mice, which may be associated with its modulation of Nox2 and Sod2 expression.NEW & NOTEWORTHY The study demonstrated that RGFP966 significantly reduced oxidative stress, inflammation, and cell apoptosis in the retina of streptozotocin-induced diabetic mice, which may be associated with Nox2 and Sod2 expression.

Abstract
BACKGROUND Acute thoracic aortic dissection (ATAD) is a fatal condition characterized by tear of intima, formation of false lumen and rupture of aorta. However, the subpopulations of normal and dissected aorta remain less studied. METHODS Single-cell RNA sequencing was performed including 5 patients with ATAD and 4 healthy controls. Immunohistochemistry and immunofluorescence were used to verify the findings. RESULTS We got 8 cell types from human ascending aorta and identified 50 subpopulations including vascular smooth muscle cells (VSMCs), endothelial cells, fibroblasts, neutrophils, monocytes and macrophages. Six transmembrane epithelial antigen of prostate 4 metalloreductase (STEAP4) was identified as a new marker of synthetic VSMCs. CytoTRACE identified subpopulations with higher differentiation potential in specified cell types including synthetic VSMCs, enolase 1+ fibroblasts and myeloid-derived neutrophils. Synthetic VSMCs-derived C-X-C motif chemokine ligand 12 (CXCL12) might interact with neutrophils and fibroblasts via C-X-C motif chemokine receptor 4 (CXCR4) and atypical chemokine receptor 3 (ACKR3), respectively, which might recruit neutrophils and induce transdifferentitation of fibroblasts into synthetic VSMCs. CONCLUSION We characterized signatures of different cell types in normal and dissected human ascending aorta and identified a new marker for isolation of synthetic VSMCs. Moreover, we proposed a potential mechanism that synthetic VSMCs might interact with neutrophils and fibroblasts via CXCL12-CXCR4/ACKR3 axis whereby deteriorating the progression of ATAD, which might provide new insights to better understand the development and progression of ATAD.

Abstract
Aortic dissection (AD) is a life-threatening disease and the detailed mechanism remains unclear. Thus, proper animal models are urgently required to better understand its pathogenesis. Our current study aims to establish a reliable, time and cost-effective mouse AD model. To conduct the meta-analysis, we searched PubMed for related studies up to 2021 and statistical analysis was conducted using Review Manager 5.4. For the animal experiment, 6-week-old male ApoE-/- mice were given β-aminopropionitrile (BAPN) at a concentration of 1 g/L for 3 weeks before being infused with saline, 1000 ng/kg/min or 2500 ng/kg/min angiotensin II (AngII) via osmotic mini pumps for 2 or 4 weeks. To determine the presence of AD, we performed B-ultrasonography, hematoxylin and eosin (H&E) staining, and van Gieson staining. The result of the meta-analysis showed that the use of BAPN and more than 2000 ng/kg/min AngII can increase the rate of AD formation, whereas administrating Ang II for more than 28 days has no significant effect on the rate of AD formation when compared with the less than 14 days group. In the present study, mice treated with BAPN combined with 2500 ng/kg/min AngII for 2 weeks (12/20) had a significantly higher AD formation rate than mice treated with BAPN combined with 1000 ng/kg/min Ang II for 4 weeks (2/10), and had a similar model formation rate compared with the mice treated withβ-aminopropionitrile combined with 2500 ng/kg/min AngII for 4 weeks (6/10). There were 3 mice (3/10) and 6 mice (6/20) who died in the group treated with β-aminopropionitrile combined with 2500 ng/kg/min AngII for 4 weeks and 2 weeks respectively, and only one mouse (1/10) died in the group treated with β-aminopropionitrile combined with 1000 ng/kg/min AngII for 4 weeks. In 6-week-old male ApoE-/- mice that received with 1 g/L BAPN in the drinking water for 3 weeks along with 2500 ng/kg/min AngII infusion via osmotic mini pumps for 2 weeks, the highest model formation rate and relative lower cumulative mortality were noted.

Abstract
Background Homocysteine (Hcy) has been indicated to be involved in pathophysiology of post stroke depression (PSD). There is a lack of research to study the relationship between Hcy metabolism genes and PSD. Our study aims to investigate the relationship among Hcy metabolism genes, Hcy, and early-onset PSD. Materials and methods We recruited 212 patients with stroke and collected their peripheral blood sample, clinical data, and laboratory test on admission. 12 single nucleotide polymorphisms (SNPs) in methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR), and methionine synthase (MTR) genes were genotyped by high-resolution melt analysis. PSD was diagnosed by DSM-V at 2 weeks after stroke. Binary logistic regression and haplotype analysis were used to examine the association between Hcy metabolism genes and PSD. Mediation analysis was performed to clarify whether the SNPs exerted their effect on PSD by affecting the Hcy level. Results 81 patients were diagnosed with PSD, and the incidence rate was 38.2%. Hcy level in PSD group was significantly higher than it in non-PSD group (p = 0.019). MTHFR rs1801133 AA genotype an A allele were associated with an elevated risk of PSD after adjustment for some confounding factors (OR = 4.021, 95% CI: 1.459∼11.080, p = 0.007 for AA genotype; OR = 1.808, 95% CI: 1.172∼2.788, p = 0.007 for A allele). Furthermore, the effect of MTHFR rs1801133 AA genotype on PSD was mediated by Hcy (OR = 1.569, 95% CI: 0.013∼3.350, p < 0.05). Conclusion MTHFR rs1801133 and Hcy were associated with PSD, and MTHFR rs1801133 may exert an effect on PSD via mediating Hcy level. This offers a new perspective for treating PSD and understanding the mechanism of PSD.

Epigenetic Regulation by microRNAs in Hyperhomocysteinemia-Accelerated Atherosclerosis. Int J Mol Sci 2022; 23:ijms232012452.

Abstract
Increased serum levels of homocysteine (Hcy) is a risk factor for cardiovascular disease and is specifically linked to various diseases of the vasculature such as atherosclerosis. However, the precise mechanisms by which Hcy contributes to this condition remain elusive. During the development of atherosclerosis, epigenetic modifications influence gene expression. As such, epigenetic modifications are an adaptive response to endogenous and exogenous factors that lead to altered gene expression by methylation and acetylation reactions of different substrates and the action of noncoding RNA including microRNAs (miRNAs). Epigenetic remodeling modulates cell biology in both physiological and physiopathological conditions. DNA and histone modification have been identified to have a crucial role in the progression of atherosclerosis. However, the potential role of miRNAs in hyperHcy (HHcy)-related atherosclerosis disease remains poorly explored and might be essential as well. There is no review available yet summarizing the contribution of miRNAs to hyperhomocystein-mediated atherogenicity or their potential as therapeutic targets even though their important role has been described in numerous studies. Specifically, downregulation of miR-143 or miR-125b has been shown to regulate VSCMs proliferation in vitro. In preclinical studies, downregulation of miR-92 or miR195-3p has been shown to increase the accumulation of cholesterol in foam cells and increase macrophage inflammation and atherosclerotic plaque formation, respectively. Another preclinical study found that there is a reciprocal regulation between miR-148a/152 and DNMT1 in Hcy-accelerated atherosclerosis. Interestingly, a couple of studies have shown that miR-143 or miR-217 may be used as potential biomarkers in patients with HHcy that may develop atherosclerosis. Moreover, the current review will also update current knowledge on miRNA-based therapies, their challenges, and approaches to deal with Hcy-induced atherosclerosis.

Abstract
Abdominal aortic aneurysm (AAA) is a prevalent vascular disease with high mortality rates upon rupture. Despite its prevalence in elderly populations, there remain limited treatment options; invasive surgical repair, while risky, is the only therapeutic intervention with proven clinical benefits. Dietary factors have long been suggested to be closely associated with AAA risks, and dietary therapies recently emerged as promising avenues to achieve non-invasive management of a wide spectrum of diseases. However, the role of dietary therapies in AAA remains elusive. In this article, we will summarize the recent clinical and pre-clinical efforts in understanding the therapeutic and mechanistic implications of various dietary patterns and therapeutic approaches in AAA.

Exosomal miR-195 in hUC-MSCs alleviates hypoxia-induced damage of trophoblast cells through tissue factor pathway inhibitor 2. Curr Res Transl Med 2022; 70:103352.

Abstract
MicroRNA-195 (miR-195) was decreased in the patients with pre-eclampsia (PE), which was implicated to modulate PE. Moreover, tissue factor pathway inhibitor 2 (TFPI2), which was highly expressed in the placenta of PE patients, was negatively correlated with miR-195 levels. This study aimed to explore the role of miR-195 in the cell therapy for the treatment of PE and the underlying mechanisms. Human umbilical cord mesenchymal stem cells (hUC-MSCs) were transfected with miR-195 mimic or mimic negative control to extract exosomes. HTR8/SVneo was incubated under hypoxia condition to induce cell damage, and co-co-cultured with exosomes derived from hUC-MSCs to evaluate its effect. Hypoxia time-dependently caused a decrease on miR-195 level with an increase on TFPI2 expression in HTR8/SVneo. MiR-195 directly bind to TFPI2 and inhibited TFPI2 expression in hUC-MSCs. Moreover, hypoxia-induced cell damage in HTR8/SVneo was significantly attenuated by co-culture with hUC-MSC-derived exosomes. Exosomes extracted from miR-195-overexpressed hUC-MSCs, could further ameliorate hypoxia-induced cell damage, due to the excessive amount of miR-195 delivered by exosomes. Exosomal miR-195 in hUC-MSCs alleviated hypoxia-induced cell damage through TFPI2, which might provide a potential therapeutic approach for pre-eclampsia.

[PMID: 36049351 DOI: 10.1016/j.intimp.2022.109177] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 08/08/2022] [Accepted: 08/15/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Aortic dissection (AD) is a fatal vascular disease in absence of effective pharmaceutical therapy. Adenosine monophosphate-activated protein kinase α (AMPKα) plays a critical role in various cardiovascular diseases. Whether AMPKα is involved in the pathogenesis of aortic dissection remains unknown. We aimed to determine whether activation of AMPKα prevents the formation of AD. METHODS AND RESULTS Reduced expression of phosphorylated AMPKα (Thr172) and exacerbated phenotypic switching were observed in human aortic tissues from aortic dissection patients compared with those in tissues from controls. In vivo, the formation of aortic dissection in ApoE-/- mice was successfully induced by continuous infusion of angiotensin II (AngII) for two weeks, characterized by the activation of vascular inflammation, infiltration of macrophages and phenotypic switching of vascular smooth muscle cells (VSMCs). rAAV2-mediated overexpression of constitutively active AMPKα (CA-AMPKα) enhanced the expression of phosphorylated AMPKα (Thr172) and attenuated AngII-induced occurrence of aortic dissection by suppressing the infiltration of macrophages, activation of vascular inflammation and phenotypic switching of VSMCs. The pathogenesis above was conversely exacerbated by rAAV2-mediated overexpression of dominant negative AMPKα2 (DN-AMPKα). In vitro, we demonstrated that the administration of an AMPK agonist (AICAR) or transfection of CA-AMPKα induced the activation of AMPKα and then ameliorated AngII-induced phenotypic switching in the VSMCs and inflammation in the bone marrow-derived macrophages (BMDMs). This could be reversed by the addition of AMPK inhibitor compound C or transfection of DN-AMPKα. CONCLUSION Impaired activation of AMPKα may increase the susceptibility to aortic dissection. Our findings verified the protective effects of AMPKα on the formation of aortic dissection and may provide evidence for clinical prevention or treatment.

Abstract
Esophageal cancer is the sixth leading cause of cancer mortalities globally with a high incidence rate. Apelin (APLN) plays regulatory roles in different organs. However, its role in esophageal cancer remains unknown. Therefore, our study aims to explore the effect of APLN on esophageal cancer. One hundred and eighty-four (184) esophageal tumor tissues samples from patients with esophageal cancer, and 11 esophageal tissues samples from healthy volunteers were analyzed for the expression of APLN. APLN was highly expressed in the tumor of patients with esophageal cancer and esophageal cancer cells. Patients with high expressions of APLN had a lower survival rate than the ones with low to medium expressions of APLN. Human esophageal carcinoma cell lines, TE-1 and ECA-109 cells were transfected with APLN siRNA to knockdown APLN, or transfected with pcDNA-APLN to overexpress APLN. Inhibition of APLN by siRNA-APLN reduced proliferative, migrative, and invasive abilities of esophageal cancer cells and promoted cell apoptosis, which could be all restored by pcDNA-APLN. Moreover, knocking down APLN by siRNA-APLN suppressed the PI3K/mTOR signaling pathway. These findings identify that APLN inhibition might ameliorate esophageal cancer through activating the PI3K/mTOR signaling pathway, thus APLN could be a potential target for esophageal cancer.

Abstract
This study was designed to explore the role of miR-146a in diabetic retinopathy (DR). 30 healthy control (HC), 50 patients with type 2 diabetes mellitus, and 48 DR patients were enrolled. Blood was collected and levels of miR-146a expression, vascular endothelial growth factor (VEGF), and three inflammatory cytokines (NF-κB, IL-1β, and TNF-α) were detected. Moreover, ARPE-19 cells were treated with miR-146a mimic or inhibitor in the presence of high glucose to evaluate its effect in vitro. DR patients had the lowest level of miR-146a and the highest level of VEGF as well as the most severe inflammation among the three groups. In addition, the miR-146a level was negatively correlated with the expression of VEGF and three inflammatory cytokines, respectively in DR patients. Moreover, VEGF expression was positively correlated with these three inflammatory cytokines in DR patients. In summary, miR-146a could inhibit VEGF expression and inflammation in DR.

Abstract
Diabetic kidney disease (DKD), is one of the most common vascular diseases caused by diabetes, eventually progressing into glomerular sclerosis. Qidantang Granule is a traditional Chinese medicine that is commonly used for DKD. However, there is still no experimental evidence for its effectiveness on DKD. 8-week-old Sprague Dawley male rats were fed on high-fat and high-sugar diet for 4 weeks, and then intraperitoneally injected with 35 mg/kg streptozotocin (STZ) to induce diabetes. Diabetic rats were randomly divided into three groups, and orally administrated with vehicle, 50 mg/kg or 200 mg/kg Qidantang Granule respectively, once daily for 9 weeks. Qidantang Granule effectively reduced food and water intake, body weight and fasting blood glucose, decreased inflammation and oxidative stress, ameliorated renal injury through suppressing PI3K signaling pathway in STZ-induced DKD rats. Our results provide experimental evidence to demonstrate the pharmacological mechanism of Qidantang Granule in the treatment of DKD.

Abstract
BACKGROUND Acute pancreatitis is a sudden inflammation of the pancreas. Although interleukin-23 (IL-23) is associated with the severity of acute pancreatitis, the underlying mechanism remains largely unknown. Herein, its regulatory mechanisms were explored in this study. METHODS RNA-sequencing analysis selected the differently expressed genes in cerulean-induced acute pancreatitis mice. Polymerase chain reaction analysis determined IL-23 expression in cyclin-dependent kinase 2 (Cdk2) short hairpin RNA (shRNA)-pretreated or DDB1-cullin-4-associated factor-2 (DCAF2)-overexpressed RAW264.7 cells or CDKs inhibitor AT7519/cullin ring-finger ubiquitin ligase inhibitor MLN4924-treated bone marrow-derived macrophages in the presence of lipopolysaccharides (LPS). Pancreatic damages were evaluated in AT7519-treated pancreatitis mice. RESULTS Pancreatitis mice displayed an increased expression on IL-23 and a decreased expression of Cdk2. Inhibiting Cdk2 by shRNA or AT7519 significantly induced IL-23 expression in LPS-treated RAW cells. Moreover, AT7519 treatment significantly aggravated the severity of acute pancreatitis in mice. Furthermore, AT7519 remarkably increased DCAF2 expression, which was also induced by MLN4924 no matter with or without AT7519 in vitro. On the contrary, overexpressing DCAF2 blocked the stimulatory effect of AT7519 on IL-23 expression. CONCLUSION Cdk2 negatively regulates IL-23 expression by inhibiting DCAF2 in acute pancreatitis, indicating that Cdk2 might serve as a promising therapeutic target for acute pancreatitis.

Abstract
The improvements in healthcare services and quality of life result in a longer life expectancy and a higher number of aged individuals, who are inevitably affected by age-associated cardiovascular (CV) diseases. This challenging demographic shift calls for a greater effort to unravel the molecular mechanisms underlying age-related CV diseases to identify new therapeutic targets to cope with the ongoing aging "pandemic". Essential for protection against external pathogens and intrinsic degenerative processes, the inflammatory response becomes dysregulated with aging, leading to a persistent state of low-grade inflammation known as inflamm-aging. Of interest, inflammation has been recently recognized as a key factor in the pathogenesis of CV diseases, suggesting inflamm-aging as a possible driver of age-related CV afflictions and a plausible therapeutic target in this context. This review discusses the molecular pathways underlying inflamm-aging and their involvement in CV disease. Moreover, the potential of several anti-inflammatory approaches in this context is also reviewed.

Abstract
OBJECTIVES Severe acute pancreatitis (SAP) is the most serious subtype of acute pancreatitis, manifested as multiple-organ failure resulting in high morbidity and mortality. Based on the role of tripartite motif-containing protein 29 (TRIM29) in immune responses, we aimed to explore its effect on SAP. METHODS Peripheral blood monocyte cells from the SAP or non-SAP patients, as well as bone marrow-derived macrophages from wild-type, TRIM29 -/- , or stimulator of interferon genes (STING) -/- mice after injecting 50 mg/kg of cerulein to induce SAP, were isolated to analyze the role of TRIM29 and STING in the SAP. RESULTS Tripartite motif-containing protein 29 was significantly reduced in SAP patients. Compared with wild-type mice, TRIM29 deficiency mice displayed more severe symptom of acute pancreatitis after cerulein injection, which were lost in TRIM29 -/- STING -/- mice. Moreover, interferon and its related genes, as well as STING degradation, were decreased in TRIM29 -/- mice. CONCLUSIONS Our study demonstrated that TRIM29 negatively regulated the severity of SAP by degrading STING at its downstream, suggesting that TRIM29 and STING might serve as therapeutic targets for SAP.

Abstract
BACKGROUND Nonalcoholic Steatohepatitis (NASH) is the most severe type of non-alcoholic fatty liver disease (NAFLD) and one of the most common chronic liver diseases, leading to the increased risk of liver failure, cirrhosis and hepatocellular carcinoma. Trans-anethole was reported to have anti-inflammatory, anti-obesity and anti-diabetic activities. However, its role in NASH remains unknown. Therefore, we aimed to explore the effect of Trans-anethole on NASH. METHODS Eight-week-old C57BL/6 mice were fed on a methionine- and choline-deficient (MCD) diet for 8 weeks to induce NASH in mice, and on the meanwhile, mice were also orally administrated with or without 100 mg/kg Trans-anethole daily to evaluate the effect of Trans-anethole on NASH. RESULTS Trans-anethole dose-dependently ameliorated liver injury in MCD diet-fed mice, then the most effective dose of Trans-anethole 100 mg/kg was chosen. Trans-anethole significantly attenuated hepatic steatosis, inflammation and hepatic fibrosis in MCD diet-induced NASH mice. Moreover, Trans-anethole reduced hepatic fibrosis by inhibiting transforming growth factor-beta signaling pathway both in vivo and in vitro. CONCLUSION Trans-anethole effectively ameliorated NASH in MCD diet-fed mice, which suggested that Trans-anethole might serve as a therapeutic strategy for NASH.

Abstract
Plasma homocysteine (HCY) is an established risk factor for cardiovascular disease CVD and stroke. However, more than two decades of intensive research activities has failed to demonstrate that Hcy lowering through B-vitamin supplementation results in a reduction in CVD risk. Therefore, doubts about a causal involvement of hyperhomocysteinemia (HHcy) and B-vitamin deficiencies in atherosclerosis persist. Existing evidence indicates that HHcy increases oxidative stress, causes endoplasmatic reticulum (ER) stress, alters DNA methylation and, thus, modulates the expression of numerous pathogenic and protective genes. Moreover, Hcy can bind directly to proteins, which can change protein function and impact the intracellular redox state. As most mechanistic evidence is derived from experimental studies with rather artificial settings, the relevance of these results in humans remains a matter of debate. Recently, it has also been proposed that HHcy and B-vitamin deficiencies may promote CVD through accelerated telomere shortening and telomere dysfunction. This review provides a critical overview of the existing literature regarding the role of HHcy and B-vitamin deficiencies in CVD. At present, the CVD risk associated with HHcy and B vitamins is not effectively actionable. Therefore, routine screening for HHcy in CVD patients is of limited value. However, B-vitamin depletion is rather common among the elderly, and in such cases existing deficiencies should be corrected. While Hcy-lowering with high doses of B vitamins has no beneficial effects in secondary CVD prevention, the role of Hcy in primary disease prevention is insufficiently studied. Therefore, more intervention and experimental studies are needed to address existing gaps in knowledge.

Abstract
BACKGROUND Diabetic osteoporosis is a common metabolic bone disorder characterized by bone loss in diabetic patients, which causes an enormous social burden due to the unsatisfactory outcome of current therapeutic strategy. METHODS Based on the importance of inflammasome activation in diabetic osteoporosis, we evaluated the protective effect of an antioxidant, rosmarinic acid (RA) in diabetic osteoporosis. Bone marrow-derived monocytes isolated from rats were treated with receptor activator of nuclear factor kappa-Β ligand (RANKL) and macrophage colony stimulating factor to differentiate into mature osteoclasts (OCs). Next OCs were stimulated with RA under high glucose condition to evaluate bone resorption. Next, streptozotocin (STZ)-injected rats were orally treated with 50 mg kg-1 RA to analyze its effect on diabetic osteoporosis. RESULTS RA inhibited high glucose-stimulated inflammation and inflammasome activation in OCs. Bone resorption was also reduced after RA treatment as shown by the resorption pits assay. Moreover, RA significantly reduced bone resorption, alleviated bone weight loss and increased bone mineral density by inhibiting the activation of NACHT-LRR-PYD domains-containing protein 3 (NLRP3) inflammasome in STZ-induced diabetic rats, leading to the improvement of diabetic osteoporosis. CONCLUSION RA effectively ameliorates diabetic osteoporosis in STZ-induced rats by inhibiting the activation of NLRP3 inflammasome in OCs, which suggests that RA might serve as a potential candidate drug for treating diabetic osteoporosis.

Abstract
BACKGROUND Chronic periodontitis (CP) is a common disease of oral cavity, and approximately 35% of adults suffered from CP. Therefore, its underlying mechanism needs to be explored for new therapeutic approaches. Chemerin as a multifunctional adipokine, is found to be highly expressed in the gingival crevicular fluid (GCF), gingival tissues and the plasma of periodontitis patients. Thus, we aimed to uncover the underlying mechanism of chemerin in CP. METHODS 36 CP patients and 25 healthy volunteers were enrolled. Periodontal ligament stem cells (PDLSCs) were isolated from CP patients and healthy ones respectively. Then normal PDLSCs or PDLSCs-differentiated osteoblasts were treated with different doses of recombinant human chemerin. RESULTS Chemerin and inflammatory cytokines, including interleukin-1β, interleukin-6 and tumor necrosis factor-α, were higher in the GCF and serum of CP patients than healthy ones. Moreover, chemerin was positively correlated with these three inflammatory cytokines respectively in CP patients. PDLSCs isolated from CP patients had higher expressions of chemerin and these cytokines than the ones isolated from normal individuals. Furthermore, chemerin dose-dependently increased inflammatory responses and inhibited osteogenic differentiation of PDLSCs. CONCLUSION Chemerin accelerated inflammatory responses and suppressed osteogenic differentiation of PDLSCs, thus chemerin might sever as a therapeutic target of CP.

Abstract
Diabetic retinopathy (DR) is the most common micro-vascular complication of diabetes, and the leading cause of vision loss and blindness globally. Due to the unsatisfied outcome of current therapies, a novel strategy needs to be developed. BV2 microglial cells were treated with 25 natural compounds respectively in the stimulation of high glucose (HG), to screen for the potential candidate drug. Streptozotocin (STZ)- induced diabetic mice were injected with different doses of the candidate Sesamin every two days for one month. Then, its protective role and possible mechanism were evaluated. Sesamin was selected as candidate drug due to its inhibition on the secretion of tumor necrosis factor-α (TNFα) in the screen assay. Sesamin also dose-dependently inhibited mRNA levels of HG-induced inflammatory cytokines, including TNFα, interleukin (IL)-1β and IL-6, activated NF-κB signaling pathway, and reduced oxidative stress by decreasing reactive oxygen species levels and increasing antioxidant enzymes in the BV2 and primary retinal microglia. Additionally, Sesamin alleviated brain-retinal barrier breakdown by Evan's blue leakage assay and reduced inflammation in Streptozotocin-induced diabetic mice. In conclusion, Sesamin effectively inhibits HG-induced microglial inflammation in the retina both in vivo and in vitro, suggesting that Sesamin might serve as a candidate drug for DR treatment.

Single-Cell Transcriptome Profiles Reveal Fibrocytes as Potential Targets of Cell Therapies for Abdominal Aortic Aneurysm. Front Cardiovasc Med 2021; 8:753711.

Abstract
Abdominal aortic aneurysm (AAA) is potentially life-threatening in aging population due to the risk of aortic rupture and a lack of optimal treatment. The roles of different vascular and immune cells in AAA formation and pathogenesis remain to be future characterized. Single-cell RNA sequencing was performed on an angiotensin (Ang) II-induced mouse model of AAA. Macrophages, B cells, T cells, fibroblasts, smooth muscle cells and endothelial cells were identified through bioinformatic analyses. The discovery of multiple subtypes of macrophages, such as the re-polarization of Trem2+Acp5+ osteoclast-like and M2-like macrophages toward the M1 type macrophages, indicates the heterogenous nature of macrophages during AAA development. More interestingly, we defined CD45+COL1+ fibrocytes, which was further validated by flow cytometry and immunostaining in mouse and human AAA tissues. We then reconstituted these fibrocytes into mice with Ang II-induced AAA and found the recruitment of these fibrocytes in mouse AAA. More importantly, the fibrocyte treatment exhibited a protective effect against AAA development, perhaps through modulating extracellular matrix production and thus enhancing aortic stability. Our study reveals the heterogeneity of macrophages and the involvement of a novel cell type, fibrocyte, in AAA. Fibrocyte may represent a potential cell therapy target for AAA.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is the most common pregnancy-related disease that increases the risk of metabolic disorders for the pregnancies and their offspring. GDM could be effectively prevented by early diagnosis and timely treatment. METHODS 120 patients with GDM and 108 gestational week-matched pregnancies with normal glucose tolerance (NGT) were enrolled in our study. Their blood samples were collected, and demographic characteristics were analysed. RESULTS Compared to NGT pregnancies, patients with GDM had increased the secretions of interleukin (IL)-33, soluble suppression of tumorigenicity 2 (sST2), IL-6 and tumour necrosis factor-α (TNF-α) in their plasma with elevated homeostatic model assessment (HOMA). Moreover, IL-33/sST2 was positively correlated with HOMA, IL-6 and TNF-α levels in the plasma of patients with GDM respectively. CONCLUSION IL-33/sST2 might serve as a novel potential biomarker for early diagnosis of GDM.

Abstract
It has been demonstrated that homocysteine (Hcy) can cause inflammatory diseases. Long noncoding RNAs (lncRNA) and microRNAs (miRNAs) are involved in this biological process, but the mechanism underlying Hcy-induced inflammation remains poorly understood. Here, we found that lncRNA TGFB3-AS1 was highly expressed in macrophages treated with Hcy and the peripheral blood monocytes from cystathionine beta-synthase heterozygous knockout (CBS+/−) mice with a high-methionine diet using lncRNA microarray. In vivo and in vitro experiments further confirmed that TGFB3-AS1 accelerated Hcy-induced inflammation of macrophages through the Rap1a/wnt signaling pathway. Meanwhile, TGFB3-AS1 interacted with Rap1a and reduced degradation of Rap1a through inhibiting its ubiquitination in macrophages treated with Hcy. Rap1a mediated inflammation induced by Hcy and serves as a direct target of miR-144. Moreover, TGFB3-AS1 regulated miR-144 by binding to pri-miR-144 and inhibiting its maturation, which further regulated Rap1a expression. More importantly, we found that high expression of TGFB3-AS1 was positively correlated with the levels of Hcy and proinflammatory cytokines in serum of healthy individuals and patients with HHcy. Our study revealed a novel mechanism by which TGFB3-AS1 promoted inflammation of macrophages through inhibiting miR-144 maturation to stay miR-144 regulated inhibition of functional Rap1a expression.

Abstract
BACKGROUND Coronary artery disease (CAD) and aortic aneurysms (AA) are two cardiovascular diseases that share a multifactorial aetiology. The influence of family history and genetics on the two diseases separately and in association is well known, but poorly elucidated. This comprehensive review aims to examine the current literature on the gene ANRIL (antisense non-coding RNA in the INK4 locus) and its associations with CAD and AA. METHODS A database search on OVID, PubMed and Cochrane to identify articles concerning single nucleotide polymorphisms (SNPs) associated with ANRIL and their respective incidences of, and impact on, CAD and AA across populations. RESULTS Cohort studies across various ethnicities reveal that various ANRIL SNPs are significantly associated separately with CAD (rs1333040, rs1333049 and rs2383207) and AA (rs564398, rs10757278 and rs1333049), and that these SNPs are present in significant proportions of the population. SNP rs1333049 is significantly associated with both diseases, but is positively correlated with AAA and negatively correlated with CAD. This review further outlines several pathophysiological links via endothelial and adventitial cells, vascular smooth muscle cells and sense gene interaction, which may explain these genetic associations identified. CONCLUSION Given the associations uncovered between ANRIL polymorphisms and CAD and AA, as well as the molecular mechanisms which may explain the underlying pathophysiology, ANRIL appears to be strongly linked with both diseases. ANRIL may hence have a future application in screening normal patients and risk stratifying patients with both diseases. Its role in linking the two diseases is yet unclear, warranting further studies.

Abstract
Selenium (Se) is considered to have antioxidant properties, which are beneficial for heart condition. Hyperhomocysteinemia (HHCY) has been suggested to potentially lead to heart failure and is characterized by cardiac fibrosis; however, investigation on the role of Se and HHCY in cardiac fibrosis is rare. Since previous studies demonstrated the important role of the long non-coding RNA maternally expressed 3 (MEG3) in some heart diseases, the present study aimed to determine how Se and MEG3 might exert regulatory effects on HCY-induced fibrosis in cardiac fibroblasts (CFs). Mouse CFs were isolated and treated with HCY and Se. The expression of α-smooth muscle actin (α-SMA), collagen I and III was detected by western blotting to reflect CF fibrosis. Reverse transcription-quantitative PCR was performed to determine the expression levels of MEG3. Inflammation and oxidative stress responses were analyzed by measuring TNF-α, IL-1β (ELISA) and reactive oxygen species levels (using a commercial kit), respectively. Cell Counting Kit-8 was used to evaluate CF proliferation. Total and phosphorylated (p) expression of janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) was evaluated by western blotting. CFs were transfected with adenovirus expressing MEG3 short-hairpin RNA to knock down MEG3 expression. Se treatment downregulated the expression level of MEG3 in HCY-stimulated CFs, whilst inhibiting the inflammatory and oxidative stress response. Furthermore, Se inhibited the increased proliferation of CFs following HCY treatment. In addition, MEG3-knockdown in CFs could improve fibrosis caused by HCY. Furthermore, the ratios of p-JAK2/JAK2 and p-STAT3/STAT3 were decreased following treatment with Se or MEG3 silencing. Taken together, the findings from the present study suggested that Se may alleviate cardiac fibrosis by downregulating the expression of MEG3 and reducing the inflammatory and oxidative stress response in CFs. This suggests that Se may be a potential therapeutic option for treating cardiac fibrosis in the future.

Abstract
BACKGROUND Inflammation underlies both the pathogenesis and prognosis in patients with acute aortic dissection (AAD). This study aimed to assess the association of ICU admission of white blood cell count (WBCc) with post-discharge mortality in these patients. METHODS Clinical data were extracted from the MIMIC-III V1.4 database. After adjusted to covariables, Cox regression analysis and Kaplan-Meier survival curve were performed to determine the relationship between WBCc on admission and post-discharge mortality (30-day, 90-day, 1-year and 5-year) in AAD patients. Subgroup analysis and receiver operating characteristic (ROC) curve analysis were used to test the performance of WBCc in predicting mortality in AAD patients. RESULTS A total of 325 eligible patients were divided into 2 groups: normal-WBCc group (≤ 11 k/uL) and high-WBCc group (> 11 K/uL). In univariate Cox regression analysis, high WBCc was significant risk predictor of 30-day, 90-day, 1-year and 5-year mortality [hazard ratio (HR), 95% CI, P 2.58 1.36-4.91 0.004; 3.16 1.76-5.70 0.000; 2.74 1.57-4.79 0.000; 2.10 1.23-3.54 0.006]. After adjusting for age and other risks, high WBCc remained a significant predictor of 30-day, 90-day and 1-year mortality in AAD patients (HR, 95% CI, P 1.994 1.058-3.76 0.033; 2.118 1.175-3.819 0.013; 2.37 1.343-4.181 0.003). The area under ROC curve of WBCc for predicting 30-day, 90-day, 1-year and 5-year mortality were 0.69, 0.70, 0.66 and 0.61, respectively. The results from subgroups analysis showed that there was no interaction in most strata and patients who were younger than 69 years of age or had history of respiratory disease with an elevated WBCc had an excess risk of 30-day mortality (HR, 95% CI, P 3.18 1.41-7.14 0.005; 3.84 1.05-14.13 0.043). CONCLUSIONS Higher than normal WBCc on admission may predict post-discharge mortality in patients with AAD.

Abstract
The current therapeutic strategy for hyperglycemia is reasonable diet and appropriate exercise with drugs, whose outcome is unsatisfied. Therefore, we aimed to explore the new candidate drug 7-Ethoxyrosmanol (7ERM) on hyperglycemia-induced endothelial dysfunction. Human umbilical vein endothelial cells (HUVECs) were treated with different doses of 7ERM in the presence of 33 mM high glucose to measure cell injury, inflammation, and reactive oxygen species (ROS) production. Then F-box/LRR-repeat protein 7 (FBXL7) knockdown by siRNA or overexpressed by plasmid in HUVECs was assessed its effect in the protective role on hyperglycemia-induced endothelial dysfunction. 7ERM time-dependently increased high glucose-induced cell injury, the secretions of pro-inflammatory cytokines and ROS production in HUVECs. Moreover, high glucose time-dependently increased the FBXL7 expressions, which could be gradually inhibited by 7ERM. FBXL7 knockdown ameliorated high glucose-induced cell injury. On the contrary, FBXL7 over-expression inhibited the protective effect of 7ERM on cell injury. In conclusion, 7ERM effectively attenuates high glucose-induced endothelial dysfunction in HUVECs by regulating FBXL7 expression, indicating its potential as a therapeutic drug to treat hyperglycemia.

Abstract
AIMS Overactivated B cells secrete pathological antibodies, which in turn accelerate the formation of abdominal aortic aneurysms (AAAs). Hyperhomocysteinaemia (HHcy) aggravates AAA in mice; however, the underlying mechanisms remain largely elusive. In this study, we further investigated whether homocysteine (Hcy)-activated B cells produce antigen-specific antibodies that ultimately contribute to AAA formation. METHODS AND RESULTS ELISA assays showed that HHcy induced the secretion of anti-beta 2 glycoprotein I (anti-β2GPI) antibody from B cells both in vitro and in vivo. Mechanistically, Hcy increased the accumulation of various lipid metabolites in B cells tested by liquid chromatography-tandem mass spectrometry, which contributed to elevated anti-β2GPI IgG secretion. By using the toll-like receptor 4 (TLR4)-specific inhibitor TAK-242 or TLR4-deficient macrophages, we found that culture supernatants from Hcy-activated B cells and HHcy plasma IgG polarized inflammatory macrophages in a TLR4-dependent manner. In addition, HHcy markedly increased the incidence of elastase- and CaPO4-induced AAA in male BALB/c mice, which was prevented in μMT mice. To further determine the importance of IgG in HHcy-aggravated AAA formation, we purified plasma IgG from HHcy or control mice and then transferred the IgG into μMT mice, which were subsequently subjected to elastase- or CaPO4-induced AAA. Compared with μMT mice that received plasma IgG from control mice, μMT mice that received HHcy plasma IgG developed significantly exacerbated elastase- or CaPO4-induced AAA accompanied by increased elastin degradation, MMP2/9 expression, and anti-β2GPI IgG deposition in vascular lesions, as shown by immunofluorescence histochemical staining. CONCLUSION Our findings reveal a novel mechanism by which Hcy-induced B cell-derived pathogenic anti-β2GPI IgG might, at least in part, contribute to HHcy-aggravated chronic vascular inflammation and AAA formation.

Abstract
Abdominal aortic aneurysm (AAA) is a common disease associated with significant cardiovascular morbidity and mortality. Up to now, there is still controversy on the choice of treatment method of AAA. Even so, the mechanisms of AAA progression are poorly defined, making targeting new therapies problematic. Current evidence favors an interaction of the hemodynamic microenvironment with local and systemic immune responses. In this review, we aim to provide an update of mechanisms in AAA progression, involving hemodynamics, perivascular adipose tissue, adventitial fibroblasts, vasa vasorum remodeling, intraluminal thrombus, and distribution of macrophage subtypes.
