NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2023; 396:1633-1646. [PMID: 36971866 DOI: 10.1007/s00210-023-02469-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 03/19/2023] [Indexed: 03/29/2023]
Abstract
Ischemia/reperfusion (I/R) injury is a tissue damage during reperfusion after an ischemic condition. I/R injury is induced by pathological cases including stroke, myocardial infarction, circulatory arrest, sickle cell disease, acute kidney injury, trauma, and sleep apnea. It can lead to increased morbidity and mortality in the context of these processes. Mitochondrial dysfunction is one of the hallmarks of I/R insult, which is induced via reactive oxygen species (ROS) production, apoptosis, and autophagy. MicroRNAs (miRNAs, miRs) are non-coding RNAs that play a main regulatory role in gene expression. Recently, there are evidence, which miRNAs are the major modulators of cardiovascular diseases, especially myocardial I/R injury. Cardiovascular miRNAs, specifically miR-21, and probably miR-24 and miR-126 have protective effects on myocardial I/R injury. Trimetazidine (TMZ) is a new class of metabolic agents with an anti-ischemic activity. It has beneficial effects on chronic stable angina by suppressing mitochondrial permeability transition pore (mPTP) opening. The present review study addressed the different mechanistic effects of TMZ on cardiac I/R injury. Online databases including Scopus, PubMed, Web of Science, and Cochrane library were assessed for published studies between 1986 and 2021. TMZ, an antioxidant and metabolic agent, prevents the cardiac reperfusion injury by regulating AMP-activated protein kinase (AMPK), cystathionine-γ-lyase enzyme (CSE)/hydrogen sulfide (H2S), and miR-21. Therefore, TMZ protects the heart against I/R injury by inducing key regulators such as AMPK, CSE/H2S, and miR-21.

Abstract
Cardiovascular disease is a global health problem. Astragaloside IV (AS-IV) is a saponin compound extracted from the roots of the Chinese herb Astragalus. Over the past few decades, AS-IV has been shown to possess various pharmacological properties. It can protect the myocardium through antioxidative stress, anti-inflammatory effects, regulation of calcium homeostasis, improvement of myocardial energy metabolism, anti-apoptosis, anti-cardiomyocyte hypertrophy, anti-myocardial fibrosis, regulation of myocardial autophagy, and improvement of myocardial microcirculation. AS-IV exerts protective effects on blood vessels. For example, it can protect vascular endothelial cells through antioxidative stress and anti-inflammatory pathways, relax blood vessels, stabilize atherosclerotic plaques, and inhibit the proliferation and migration of vascular smooth muscle cells. Thus, the bioavailability of AS-IV is low. Toxicology indicates that AS-IV is safe, but should be used cautiously in pregnant women. In this paper, we review the mechanisms of AS-IV prevention and treatment of cardiovascular diseases in recent years to provide a reference for future research and drug development.

Abstract
Ginkgo biloba extract (GBE) helps lower cardiovascular disease risk. Diabetes mellitus (DM)-induced endothelial dysfunction is a critical and initiating factor in the beginning of diabetic vascular complications. It was reported that GBE causes an endothelial-dependent relaxation. This study was designed to figure out the molecular basis on which GBE protects from endothelial dysfunction in diabetes because the underlying mechanisms are unclear. Studies were performed in a normal control group and streptozotocin/nicotinamide-induced DM group. In aortas, notably diabetic aortas, GBE, and ginkgolide B (GB), a constituent of GBE, produced a dose-dependent relaxation. The relaxation by GB was abolished by prior incubation with L-NNA (an endothelial nitric oxide synthase (NOS) inhibitor), LY294002 (a phosphoinositide 3-kinase (PI3K) inhibitor), and Akt inhibitor, confirming the essential role of PI3K/Akt/eNOS signaling pathway. We also demonstrated that GB induced the phosphorylation of Akt and eNOS in aortas. The superoxide dismutase1 (SOD1) expression level decreased in DM aortas, but GB stimulation increased SOD activity and SOD1 expression in DM aortas. Our novel findings suggest that in DM aortas, endothelial-dependent relaxation induced by GB was mediated by activation of SOD1, resulting in activation of the Akt/eNOS signaling pathway.

Abstract
The herb Astragali Radix is a food-medicine herb. A major component of Astragali Radix, astragaloside IV (AS-IV), has neuroprotective effects in IS, but its mechanisms are not well understood. Our research used a transient middle cerebral artery occlusion (MCAO) rat model for longitudinal multi-omics analyses of the side of the brain affected by ischemia. Based on transcriptomic and proteomic analysis, we found that 396 differential expression targets were up-regulated and 114 differential expression targets were down-regulated. A total of 117 differential metabolites were identified based on metabonomics. Finally, we found 8 hub genes corresponding to the compound-reaction-enzyme-gene network using the Metscape plug-in for Cytoscape 3.7.1. We found that the related key metabolites were 3,4-dihydroxy-L-phenylalanine, 2-aminomuconate semialdehyde, (R)-3-hydroxybutanoate, etc., and the affected pathways were tyrosine metabolism, tryptophan metabolism, butanoate metabolism, purine metabolism, etc. We further validated these targets using 4D-PRM proteomics and found that seven targets were significantly different, including Aprt, Atic, Gaa, Galk1, Glb1, Me2, and Hexa. We aimed to uncover the mechanism of AS-IV in the treatment of ischemic brain injury through a comprehensive strategy combining transcriptomics, proteomics, and metabolomics.

ENVIRONMENTAL TOXICOLOGY 2023; 38:534-544. [PMID: 36322813 DOI: 10.1002/tox.23696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Revised: 10/03/2022] [Accepted: 10/13/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Atherosclerosis is a main cause of multiple cardiovascular diseases, and cell damage of human umbilical vein endothelial cells (HUVECs) was reported to participate in the development of atherosclerosis. In this study, we aimed to study the action of Astragaloside IV (ASV) on AS development using in vitro AS cell model. METHODS MTT assay, EdU staining assay, and flow cytometry were utilized for detection of cell proliferation and apoptosis, respectively. The protein expression of histone deacetylase 9 (HDAC9), Bax, Bcl-2, p-P65, P65, p-IκBα, and IκBα was gaged using western blot. The angiogenesis was evaluated by tube formation assay. The inflammatory response was evaluated by ELISA kits. SOD activity and MDA level were detected using the matched commercial kits. RT-qPCR was used for HDAC9 mRNA expression measurement. RESULTS Oxidized low-density lipoprotein (ox-LDL) significantly repressed cell proliferation, angiogenesis, and enhanced apoptosis, inflammation, and oxidative stress in HUVECs. ASV addition could alleviate ox-LDL-caused cell damage in HUVECs. Moreover, HDAC9 was overexpressed in AS patients and AS cell model. Functionally, HDAC9 knockdown also exhibited the protective role in ox-LDL-treated HUVECs. In addition, ASV treatment protected against ox-LDL-induced damage in HUVECs via targeting HDAC9. ASV could inactivate the NF-κB pathway via regulating HDAC9 in AS cell model. CONCLUSION ASV exerted the protective effects on ox-LDL-induced damage in HUVECs through the HDAC9/NF-κB axis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cardiovascular diseases are still the leading cause of death worldwide. Heart failure (HF), as the terminal stage of many cardiovascular diseases, has brought a heavy burden to the global medical system. Microvascular rarefaction (decreased myocardial capillary density) with reduced coronary flow reserve is a hallmark of HF and therapeutic myocardial angiogenesis is now emerging as a promising approach for the prevention and treatment in HF. Traditional Chinese medicine (TCM) has made remarkable achievements in the treatment of many cardiovascular diseases. Growing evidence have shown that their protective effect in HF is closely related to therapeutic angiogenesis. AIM OF THE STUDY This review is to enlighten the therapeutic effect and pro-angiogenic mechanism of TCM in HF, and provide valuable hints for the development of pro-angiogenic drugs for the treatment of HF. MATERIALS AND METHODS The relevant information about cardioprotective TCM was collected from electronic scientific databases such as PubMed, Web of Science, ScienceDirect, and China National Knowledge Infrastructure (CNKI). RESULTS The studies showed that TCM formulas, extracts, and compounds from herbal medicines can provide therapeutic effect in HF with their pro-angiogenic activity. Their actions are achieved mainly by regulating the key angiogenesis factors particularly VEGF, as well as related regulators including signal molecules and pathways, non-coding miRNAs and stem cells. CONCLUSION TCM and their active components might be promising in therapeutic angiogenesis for the treatment of HF.

Abstract
Angiogenesis, the formation of new capillaries from pre-existing vascular networks, plays an important role in many physiological and pathological processes. The use of pro-angiogenic agents has been proposed as an attractive approach for promoting wound healing and treating vascular insufficiency-related problems, such as ischemic heart disease and stroke, which are the leading causes of death worldwide. Traditional herbal medicine has a long history; however, there is still a need for more in-depth studies and evidence-based confirmation from controlled and validated trials. Many in vitro and in vivo studies have reported that herbal medicines and their bioactive ingredients exert pro-angiogenic activity. The most frequently studied pro-angiogenic phytochemicals include ginsenosides from Panax notoginseng, astragalosides and calycosin from Radix Astragali, salvianolic acid B from Salvia miltiorrhiza, paeoniflorin from Radix Paeoniae, ilexsaponin A1 from Ilex pubescens, ferulic acid from Angelica sinensis, and puerarin from Radix puerariae. This review summarizes the progress in research on these phytochemicals, particularly those related to pro-angiogenic mechanisms and applications in ischemic diseases, tissue repair, and wound healing. In addition, an outline of their limitations and challenges during drug development is presented.

Abstract
Aims Bladder outlet obstruction (BOO) and the consequent low contractility of detrusor are the leading causes of voiding dysfunction. In this study, we aimed to evaluate the pharmacological activity of astragaloside IV (AS-IV), an antioxidant biomolecule that possess beneficial effect in many organs, on detrusor contractility and bladder wall remodeling process. Methods Partial BOO (pBOO) was created by urethral occlusion in female rats, followed by oral gavage of different dose of AS-IV or vehicle. Cystometric evaluation and contractility test were performed. Bladder wall sections were used in morphology staining, and bladder tissue lysate was used for ELISA assay. Primary smooth muscle cells (SMCs) derived from detrusor were used for mechanism studies. Results Seven weeks after pBOO, the bladder compensatory enlarged, and the contractility in response to electrical or chemical stimuli was reduced, while AS-IV treatment reversed this effect dose-dependently. AS-IV also showed beneficial effect on reversing the bladder wall remodeling process, as well as reducing ROS level. In mechanism study, AS-IV activated mitophagy and alleviated oxidative stress via an AMPK-dependent pathway. Conclusion Out data suggested that AS-IV enhanced the contractility of detrusor and protected the bladder from obstruction induced damage, via enhancing the mitophagy and restoring mitochondria function trough an AMPK-dependent way.

Abstract
Background and aims: Long-term peritoneal dialysis (PD) causes intestinal dysfunction, including constipation, diarrhea, or enteric peritonitis. However, the etiology and pathogenesis of these complications are still unclear and there are no specific drugs available in the clinic. This study aims to determine whether Astragaloside IV (AS IV) has therapeutic value on PD-induced intestinal epithelial barrier dysfunction in vivo and in vitro. Methods: We established two different long-term PD treatment mice models by intraperitoneally injecting 4.25% dextrose-containing peritoneal dialysis fluid (PDF) in uremia mice and normal mice, which were served as controls. In addition, PDF was applied to T84 cells in vitro. The therapeutic effects of AS IV on PD-induced intestinal dysfunction were then examined by histopathological staining, transmission electron microscopy, western blotting, and reverse transcription polymerase chain reaction. The protein levels of protein kinase B (AKT), glycogen synthase kinase 3β (GSK-3β) and β-catenin were examined after administration of AS IV. Results: In the present study, AS IV maintained the intestinal crypt, microvilli and desmosome structures in an orderly arrangement and improved intestinal epithelial permeability with the up-regulation of tight junction proteins in vivo. Furthermore, AS IV protected T84 cells from PD-induced damage by improving cell viability, promoting wound healing, and increasing the expression of tight junction proteins. Additionally, AS IV treatment significantly increased the levels of phosphorylation of AKT, inhibited the activity GSK-3β, and ultimately resulted in the nuclear translocation and accumulation of β-catenin. Conclusion: These findings provide novel insight into the AS IV-mediated protection of the intestinal epithelial barrier from damage via the AKT-GSK3β-β-catenin signal axis during peritoneal dialysis.

Abstract
BACKGROUND Therapeutic angiogenesis by transplantation of autologous/allogeneic adipose stem cells (ADSCs) is a potential method for the treatment of critical limb ischemia (CLI). However, the therapeutic efficiency is limited by poor viability, adhesion, migration and differentiation after cell transplantation into the target area. Astragaloside IV (AS-IV), one of the main active components of Astragalus, has been widely used in the treatment of ischemic diseases and can promote cell proliferation and angiogenesis. However, there is no report on the effect of AS-IV on ADSCs and its effect on hindlimb ischemia through cell transplantation. PURPOSE The purpose of this study was to elucidate that AS-IV pretreatment enhances the therapeutic effect of ADSC on critical limb ischemia, and to characterize the underlying molecular mechanisms. METHODS ADSCs were obtained and pretreated with the different concentration of AS-IV. In vitro, we analyzed the influence of AS-IV on ADSC proliferation, migration, angiogenesis and recruitment of human umbilical vein endothelial cells (HUVECs) and analyzed the relevant molecular mechanism. In vivo, we injected drug-pretreated ADSCs into a Matrigel or hindlimb ischemia model and evaluated the therapeutic effect by the laser Doppler perfusion index, immunofluorescence, and histopathology. RESULTS In vitro experiments showed that AS-IV improved ADSC migration, angiogenesis and endothelial recruitment. The molecular mechanism may be related to the upregulation of CXC receptor 2 (CXCR2) to promote the phosphorylation of focal adhesion kinase (FAK). In vivo, Matrigel plug assay showed that ADSCs pretreated with AS-IV have stronger angiogenic potential. The laser Doppler perfusion index of the hindlimbs of mice in the ADSC/AS-IV group was significantly higher than the laser Doppler perfusion index of the hindlimbs of mice of the ADSC group and the control group, and the microvessel density was significantly increased. CONCLUSION Our results demonstrate that AS-IV pretreatment of ADSC improves their therapeutic efficacy in ameliorating severe limb exclusion symptomology through CXCR2 induced FAK phosphorylation, which will bring new insights into the treatment of severe limb ischemia.

Abstract
Background Hypoxia is an important cause of myocardial injury due to the heart’s high susceptibility to hypoxia. Astragaloside IV (AS-IV) is the main component of Astragalus membranaceus and could exert cardiac protective role. Here, the effect of AS-IV on hypoxia-injured H9c2 cardiomyocytes was elucidated. Methods First, H9c2 cells were exposed to hypoxia and/or AS-IV treatment. Cell apoptosis, death, and viability as well as hypoxia-inducible factor 1α (HIF-1α) expression and apoptotic proteins were analyzed. Next, transfection of si-HIF-1α into H9c2 cells was carried out to test whether upregulation and stabilization of HIF-1α influences the effect of AS-IV on hypoxia-treated H9c2 cells. Furthermore, the regulatory role of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling on HIF-1α levels was examined. Results Hypoxia suppressed viability and promoted the apoptosis and death of H9c2 cells. AS-IV eliminated hypoxia-induced H9c2 injury. Moreover, HIF-1α signaling was further activated and stabilized by AS-IV in hypoxia-challenged H9c2 cells. Downregulation of HIF-1α suppressed the function of AS-IV in hypoxia-challenged H9c2 cells. AS-IV promoted JAK2/STAT3 signaling in hypoxia-induced injury. The beneficial functions of AS-IV in hypoxia-exposed H9c2 cells were linked to HIF-1α upregulation and JAK2/STAT3 signaling activation. Conclusions AS-IV relieved H9c2 cardiomyocyte injury after hypoxia, possibly by activating JAK2/STAT3-mediated HIF-1α signaling.

Abstract
Both osteoblasts and preosteoclasts contribute to the coupling of osteogenesis and angiogenesis, regulating bone regeneration. Astragaloside IV (AS-IV), a glycoside of cycloartane-type triterpene derived from the Chinese herb Astragalus membranaceus, exhibits various biological activities, including stimulating angiogenesis and attenuating ischemic-hypoxic injury. However, the effects and underlying mechanisms of AS-IV in osteogenesis, osteoclastogenesis, and bone regeneration remain poorly understood. In the present study, we found that AS-IV treatment inhibited osteoclastogenesis, preserved preosteoclasts, and enhanced platelet-derived growth factor-BB (PDGF-BB)-induced angiogenesis. Additionally, AS-IV promoted cell viability, osteogenic differentiation, and angiogenic gene expression in bone marrow mesenchymal stem cells (BMSCs). The activation of AKT/GSK-3β/β-catenin signaling was found to contribute to the effects of AS-IV on osteoclastogenesis and osteogenesis. Furthermore, AS-IV accelerated bone regeneration during distraction osteogenesis (DO), as evidenced from the improved radiological and histological manifestations and biomechanical parameters, accompanied by enhanced angiogenesis within the distraction zone. In summary, AS-IV accelerates bone regeneration during DO, by enhancing osteogenesis and preosteoclast-induced angiogenesis simultaneously, partially through AKT/GSK-3β/β-catenin signaling. These findings reveal that AS-IV may serve as a potential bioactive molecule for promoting the coupling of osteogenesis and angiogenesis, and imply that AKT/GSK-3β/β-catenin signaling may be a promising therapeutic target for patients during DO treatment.

Abstract
INTRODUCTION Astragaloside IV (AS-IV) is a natural herb extract and a popular compound used in traditional Chinese medicine because of its effect on multiple biological processes, such as promotion of cell proliferation, improvement in cardiopulmonary and vascular function, and promotion of angiogenesis around wounds, leading to accelerated wound healing. Vascular regeneration primarily results from the differentiation of endothelial progenitor cells (EPCs). Biomedical acceleration of angiogenesis and differentiation of EPCs around the wound remain challenging. MATERIALS AND METHODS In this study, we treated human umbilical cord blood-derived EPCs with AS-IV and cultured them on 2-dimensional (tissue culture polystyrene) and 3-dimensional culture plates (3DPs). These cultured cells were then combined with human blood plasma gel and applied on the skin of nude mice in an attempt to repair full-thickness skin defects. RESULTS The results show that using 3DP culture could increase vascular-related gene expression in EPCs. Furthermore, 12.5 μg/mL AS-IV-treaded EPCs were combined with plasma gels (P-3DP-EPC12.5) and showed enhanced vascular-related protein expression levels after 3 days of culture. Finally, P-3DP-EPC12.5s were used to repair full-thickness skin defects in nude mice, and we could register a wound healing rate greater than 90% by day 14. CONCLUSIONS Based on these results, we concluded that we have developed a potential therapeutic approach for wound healing using plasma gel containing 3-dimensional surface-cultured AS-IV-treated EPCs.

Both Hypoxia-Inducible Factor 1 and MAPK Signaling Pathway Attenuate PI3K/AKT via Suppression of Reactive Oxygen Species in Human Pluripotent Stem Cells. Front Cell Dev Biol 2021; 8:607444. [PMID: 33553145 PMCID: PMC7859355 DOI: 10.3389/fcell.2020.607444] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Accepted: 12/15/2020] [Indexed: 12/15/2022] Open
Abstract
Mild hypoxia (5% O2) as well as FGFR1-induced activation of phosphatidylinositol-4,5-bisphosphate 3-kinase/protein kinase B (PI3K/AKT) and MAPK signaling pathways markedly support pluripotency in human pluripotent stem cells (hPSCs). This study demonstrates that the pluripotency-promoting PI3K/AKT signaling pathway is surprisingly attenuated in mild hypoxia compared to the 21% O2 environment. Hypoxia is known to be associated with lower levels of reactive oxygen species (ROS), which are recognized as intracellular second messengers capable of upregulating the PI3K/AKT signaling pathway. Our data denote that ROS downregulation results in pluripotency upregulation and PI3K/AKT attenuation in a hypoxia-inducible factor 1 (HIF-1)-dependent manner in hPSCs. Using specific MAPK inhibitors, we show that the MAPK pathway also downregulates ROS and therefore attenuates the PI3K/AKT signaling—this represents a novel interaction between these signaling pathways. This inhibition of ROS initiated by MEK1/2–ERK1/2 may serve as a negative feedback loop from the MAPK pathway toward FGFR1 and PI3K/AKT activation. We further describe the molecular mechanism resulting in PI3K/AKT upregulation in hPSCs—ROS inhibit the PI3K's primary antagonist PTEN and upregulate FGFR1 phosphorylation. These novel regulatory circuits utilizing ROS as second messengers may contribute to the development of enhanced cultivation and differentiation protocols for hPSCs. Since the PI3K/AKT pathway often undergoes an oncogenic transformation, our data could also provide new insights into the regulation of cancer stem cell signaling.

Abstract
Kidney transplantation is the preferred treatment for patients with end-stage renal disease. However, various types of kidney graft injury after transplantation are still key factors that affect the survival of the kidney graft. Therefore, exploring the underlying mechanisms involved is very important. Current diagnostic measures for kidney graft injury (including needle biopsy, blood creatinine, eGFR, etc.) have many limiting factors such as invasiveness, insufficient sensitivity and specificity, so they cannot provide timely and effective information to clinicians. As for kidney grafts that have occurred injury, the traditional treatment has a little efficacy and many side effects. Therefore, there is an urgent need for developing new biomarkers and targeted treatment for kidney graft injury. Recently, studies have found that miRNAs are involved in the regulation of the progression of kidney graft injury. At the same time, it has high stability in blood, urine, and other body fluids, so it is suggested to have the potential as a biomarker and therapeutic target for kidney graft injury. Here, we reviewed the miRNAs involved in the pathophysiology of kidney graft injury such as ischemia/reperfusion injury, acute rejection, drug-induced nephrotoxicity, chronic allograft dysfunction, BK virus infection, and the latest advances of miRNAs as biomarkers and therapeutic targets of kidney graft injury, then summarized the specific data of miRNAs expression level in kidney graft injury, which aims to provide a reference for subsequent basic research and clinical transformation.

Abstract
Context: Osteoarthritis (OA) is a degenerative arthrosis sickness. Astragaloside IV (AS-IV) functions by relieving inflammatory damage.Objective: We aimed to investigate the mechanism by which AS-IV protects ATD cells from lipopolysaccharide (LPS)-induced damage.Materials and methods: ATDC5 cells were transfected with miR-203 inhibitor and NC inhibitor (150 nM) or pEX-MyD88 and sh-MyD88 (50 nM) for 48 h, pre-treated by 15 μg/mL AS-IV for 24 h, then treated by 5 μg/mL LPS for 12 h. Dual-luciferase activity testing was used to determine whether miR-203 could bind to MyD88. CCK-8 and flow cytometry were used to detect cell activity and apoptosis, respectively, and qRT-PCR, western blots, and ELISA were performed to detect expression levels of miR-203 and inflammatory cytokines.Results: Based on the 50% inhibiting concentration (IC50), there was no significant difference of AS-IV (0 to 15 μg/mL) on cell viability. Fifteen μg/mL was the optimal concentration of AS-IV in treating LPS-induced inflammatory damage in subsequent experiments since this was a semi-lethal concentration. AS-IV significantly reduces LPS-induced viability, apoptosis and the release of TNF-α, IL-6 and iNOS mainly through up-regulating miR-203. Further, MyD88 was a target gene of miR-203 and negatively regulated by miR-203. Knockdown of MyD88 inhibited LPS-induced inflammatory damage by inhibiting the NF-κB signal pathway.Discussion and conclusions: AS-IV protects ATDC5 cells against LPS-induced damage mainly via regulating miR-203/MyD88. Our results support a theoretical basis for in-depth study of the function of AS-IV and the clinical cure of OA.

Abstract
HIF-1α is an important factor regulating oxygen balance in mammals, and its expression is closely related to various physiological and pathological conditions of the body. Because HIF-1α plays an important role in the occurrence and development of cancer and other diseases, it has become an enduring research hotspot. At the same time, natural medicines and traditional Chinese medicine compounds have amazing curative effects in various diseases related to HIF-1 subtype due to their unique pharmacological effects and more effective ingredients. Therefore, in this article, we first outline the structure of HIF-1α and the regulation related to its expression, then introduce various diseases closely related to HIF-1α, and finally focus on the regulation of natural medicines and compound Chinese medicines through various pathways. This will help us understand HIF-1α systematically, and use HIF-1α as a target to discover more natural medicines and traditional Chinese medicines that can treat related diseases.

Abstract
Amyotrophic lateral sclerosis (ALS), also known as a major type of motor neuron disease, is a disease characterized by the degeneration of both upper and lower motor neurons. Astragaloside IV (AST) is one of the most effective compounds isolated from Astragalus membranaceus. Echinacoside (ECH) is also an active constituent in Cistanche tubulosa. These two herbs had been used in treating disease described like ALS in ancient China under the guidance of traditional Chinese medicine theory and now they are still being used extensively for ALS in current Chinese medicine practice, but whether AST or ECH has effect on ALS disease condition is still unclear. Survivals of primary cultured neuron and astrocyte were determined by the MTS assay. Proteins including GLT1 and GFAP, from SOD1 G93A Tg (transgenic) astrocyte lysate were determined by Western blot. Synaptic markers, PSD95 and VGLUT1, were stained by immunofluorescence and observed by a confocal microscope. Proper dilution of AST and ECH was confirmed to be not harmful to both astrocytes and neurons. AST and ECH enhanced neuronal synaptic markers density or intensity/area in different aspects. Both AST and ECH could significantly rescue SOD1 astrocyte conditional medium-treated neuronal survival and synapse loss. Ten micromolars ECH could significantly rescue the suppressed GLT1 level expressed by SOD1 Tg astrocyte. This present research proved that AST and ECH could benefit neuronal properties and rescue certain dysfunction, such as GLT1 low expression, loss of neuron-supporting function, of astrocytes under SOD1 condition.

Abstract
BACKGROUND Astragaloside IV (AS-IV) is one of the main active ingredients of Astragalusmembranaceus. Studies have shown that AS-IV stimulates angiogenesis, including cell proliferation, migration, and neovascularization. However, the relevant mechanism remains unclear. OBJECTIVE This study aims to investigate whether AS-IV activates the HIF/VEGF/Notch signaling pathway through miRNA-210 to promote angiogenesisafter ischemic stroke. METHODS The present study established a rat model of middle cerebral artery occlusion (MCAO) and cultured human umbilical vein endothelial cells (HUVECs) under hypoxic conditions in vitro to investigate the role of AS-IV in promoting angiogenesis and reveal its underlying mechanism. Through in vivo studies, the area of cerebral infarction was determined by 2,3,5-triPhenyltetrazolium chloride (TTC) staining. Immunofluorescence staining and RT-qPCR were used to detect the expression changes of miRNA-210 and ephrinA3 in the ischemic cortex after ischemia. Through in vitro studies, cell proliferation was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Subsequently, angiogenesis experiments were performed to observe the angiogenic ability. RESULTS Results revealed that AS-IV significantly reduced infarct size, promoted cell proliferation and ductal formation, and inhibited the expression of the target gene ephrinA3 by increasing the expression of miRNA-210 and inducing activation of the HIF-VEGF-Notch signaling pathway. CONCLUSIONS AS-IV promotes cerebral protection following angiogenesis and ischemic brain injury. The specific mechanism was activating the HIF/VEGF/Notch signaling pathway via miRNA-210.

Abstract
Sulfur dioxide (SO2) is a common exogenous atmospheric pollutant. Studies have shown that SO2 can cause vasodilation as a gas signaling molecule, but the specific signaling pathways are not well understood. This study aimed to explore the underlying mechanism behind the effects of SO2 on vasodilation of isolated rat aorta. The results showed that when the dose of SO2 was 30 μM, the vasodilation of endothelium-intact rings was partially suppressed by LY294002 and NG-nitro-l-arginine methyl ester, and the protein levels of phosphoinositide 3-kinase (PI3K), p-Akt, and p-endothelial nitric oxide synthase (p-eNOS) were significantly increased. When the dose of SO2 was 300 μM or 1500 μM, the vasodilation of endothelium-denuded rings did not change after application of the inhibitor, but the protein levels of PI3K, p-Akt, and p-eNOS were significantly decreased, and the activity of NOS and the level of nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) were significantly increased. We speculate that the mechanism of SO2-induced vasodilatation likely involved the endothelial PI3K/Akt/eNOS and NO/cGMP signal pathways. In addition, at the concentration of 1500 μM, SO2 markedly increased the level of caspase-3 and caspase-9. The results suggest that high concentrations of SO2 may cause damage to blood vessels. This study will help to further inform the etiologies of SO2-related cardiovascular disease.

Abstract
CONTEXT Heart failure (HF) is one of the most serious diseases worldwide. Astragaloside IV (ASI) is widely used for the treatment of cardiovascular disease in China. OBJECTIVE To evaluate the protective effect of ASI on the HF in a Sprague-Dawley rat model of left coronary artery ligation, and investigate the angiogenesis-related mechanisms. MATERIALS AND METHODS Left coronary artery was ligated to induce a rat model of HF, and the rats were treated with vehicle (saline) or different doses of ASI (0.1, 0.3 and 1 mg/kg/day) by oral gavage for 6 weeks. Cardiac function was evaluated by echocardiography. Infarct size was determined by triphenyltetrazolium chloride staining. Cardiac vascular density was analyzed by microangiography. Real-time PCR, Western blot and chromatin immunoprecipitation were performed to investigate the mechanisms. RESULTS ASI treatment improved the body weight and survival rate of HF rats, as well as the cardiac function of HF rats, with significantly improved ejection fraction (75.27 ± 5.75% vs. 36.26 ± 4.14%) and fractional shortening (45.39 ± 3.66% vs. 17.88 ± 1.32%). ASI reduced the infarct size of the HF rats by 47%. ASI promoted angiogenesis, with increased vascular density (2.08-fold) and induced mRNA expression of CD31 (1.81-fold) and VEGF (2.70-fold) in the ischemic heart. Furthermore, ASI induced the phosphorylation of JAK (1.89-fold) and STAT3 (2.95-fold), as well as the activity of VEGF promoter which was regulated by STAT3. DISCUSSION AND CONCLUSIONS ASI alleviated HF by promoting angiogenesis through JAK-STAT3 pathway, providing novel alternative strategies to prevent HF in the future.

Abstract
Heart failure is one of the major causes of mortality worldwide and it is the end stage of sev-eral cardiovascular diseases. Traditional Chinese medicine has been used in the management of heart failure for a long time. Only until recently, well-designed clinical trials have been put into practice to study the efficacies of Chinese herbs. Extensive studies have also been carried out to explore the under-lying mechanisms of pharmaceutical actions of Chinese herbs. In this study, we will summarize the frequently used Chinese herbs, formulae and patent Chinese drugs in treating patients with heart failure and review published clinical evaluations of Chinese herbs in treating cardiovascular diseases. The mechanisms by which Chinese herbs exert cardio-protective effects will also be reviewed. In the end, we will point out the limitations of current studies and challenges facing modernization of traditional Chi-nese medicine.

Abstract
Background Endothelial injury is the main mechanism of atherosclerosis, and is caused by oxidized low-density lipoprotein (ox-LDL). Astragaloside IV (AS-IV) is the primary active ingredient of the Chinese herb Huangqi, and exhibits antioxidant and anti-inflammatory properties in cardiovascular diseases. This study investigated the protective effect of AS-IV in human umbilical vein endothelial cells (HUVECs). Material/Methods HUVEC cells were induced with ox-LDL to establish an in vitro atherosclerosis model. Then HUVECs were pretreated for 1 h with AS-IV at different concentrations (10, 20, and 50 μM) and then exposed to ox-LDL (100 μg/mL) for 48 h. The cell viability, lactate dehydrogenase (LDH) release, apoptosis, migration, intracellular reactive oxygen species (ROS), and NADPH oxidase activity of HUVECs were measured. qRT-PCR was performed to measure the mRNA expressions of Nrf2, HO-1, TNFα, and IL-6. Enzyme-linked immunosorbent assay (ELISA) was performed to measure the supernatant contents of TNFα and IL-6. Results Exposure of HUVECs to ox-LDL reduced cell viability and migration, induced apoptosis, and increased intracellular ROS production and NADPH oxidase. Pretreatment with AS-IV (10, 20, and 50 μM) significantly enhanced the cell viability and migration, suppressed LDH release, apoptosis, ROS production, and NADPH oxidase in HUVECs, in a concentration-dependent manner. The AS-IV (50 μM) alone did not show significant differences from control. AS-IV increased mRNA expressions of Nrf2 and HO-1 and decreased mRNA expressions of TNFα and IL-6 in the ox-LDL-HUEVC cells. Furthermore, AS-IV reduced supernatant contents of TNFα and IL-6. Conclusions Astragaloside IV prevents ox-LDL-induced endothelial cell injury by reducing apoptosis, oxidative stress, and inflammatory response.

Hypoxia destroys the microstructure of microtubules and causes dysfunction of endothelial cells via the PI3K/Stathmin1 pathway. Cell Biosci 2019; 9:20.

Abstract
Background Endothelial cells (EC) are sensitive to changes in the microenvironment, including hypoxia and ischemia. Disruption of the microtubular network has been reported in cases of ischemia. However, the signaling pathways involved in hypoxia-induced microtubular disruption are unknown. The purpose of this study was to investigate the molecular mechanisms involved in hypoxia-induced microtubular disassembly in human umbilical vein endothelial cells (HUVECs). Results HUVECs were cultured under normoxic or hypoxic conditions and pretreated with or without colchicine or paclitaxel. The MTT assay, Transwell assay, trans-endothelial permeability assay, and 5-bromo-2′-deoxy-uridine staining were used to test the survival rate, migration, permeability, and proliferation of cells, respectively. Transmission electron microscopy and phalloidin staining were used to observe the microstructure and polymerization of microtubules. The results show that the functions of HUVECs and the microtubular structure were destroyed by hypoxia, but were protected by paclitaxel and a reactive oxygen species (ROS) inhibitor. We further used western blot, a luciferase assay, and co-immunoprecipitation to describe a non-transcription-independent mechanism for PI3K activation-inhibited microtubular stability mediated by Stathmin1, a PI3K interactor that functions in microtubule depolymerization. Finally, we determined that hypoxia and ROS blocked the interaction between PI3K and Stathmin1 to activate disassembly of microtubules. Conclusion Thus, our data demonstrate that hypoxia induced the production of ROS and damaged EC function by destroying the microtubular structure through the PI3K/stathmin1 pathway.

Abstract
The current study aimed to assess the role and mechanism of astragaloside IV (AS-IV) in myocardial infarction. A myocardial infarction model was established via the ligation of the left anterior descending artery. Rats were randomly divided into sham, DMSO, model, AS-IV, AS-IV-CID755673 and CID755673 inhibitor groups. Rats were then sacrificed following 4 weeks of treatment and segmental heart samples were obtained for hematoxylin and eosin, and masson staining. The expression of PKD1, HDAC5 and VEGF were analyzed using immunohistochemistry, reverse transcription polymerase chain reaction and western blotting. Compared with the sham and DMSO groups, the morphology of myocardium in the model and CID755673 inhibitor groups were disordered and exhibited necrotic myocardial cells and collagen tissues. Following treatment with AS-IV, the morphology of the myocardium was markedly improved and the number of new blood vessels increased. However, following treatment with CID755673, the myocardial tissue of rats became disordered, with an increased number of necrotic cells and the closure of certain vessels. The expression of PKD1, HDAC5 and VEGF mRNA and protein in myocardial tissue of model group and CID755673 inhibitor group were significantly lower than the other four groups (P<0.05), whereas these levels in the AS-IV group were significantly higher than those in the other five groups (P<0.01). Additionally, the AS-IV-CID755673 group exhibited significantly higher levels of PKD1, HDAC5 and VEGF mRNA and protein than the sham, DMSO, CID755673 inhibitor and model groups (P<0.05). Furthermore, the protein expression of pS205 PKD1, pS259 HDAC5 and pTyr951 VEGF in the myocardium of rats was comparable with that of PKD1, HDAC5 and VEGF. AS-IV may partly promote the angiogenesis of myocardial tissue in rats with myocardial infarction via the PKD1-HDAC5-VEGF pathway.

Abstract
BACKGROUND Astragalosidic acid (LS-102) is a new water-soluble derivative of astragaloside IV - a major effective component isolated from the Chinese herb Astragali Radix. Our previous study showed that LS-102 exhibited potent cardiovascular activity. PURPOSE The objective of this study was to investigate the pharmacokinetic properties of LS-102 after single-dose, oral administration in beagle dogs by developing and validating an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method. METHOD AND RESULT The chromatographic separation was performed on a Acquity HSS C18 column (100 mm × 2.1 mm, 1.8 µm) by a gradient elution using a mobile phase consisting of water and acetonitrile at a flow rate of 0.35 ml/min. The analytes were detected with a triple quadrupole tandem mass spectrometry in multiple reaction monitoring mode. Method validation revealed a wide linearity over the range of 2.0-10,000 ng/ml together with satisfactory intra- and inter-day precision, accuracy, and recovery. Stability testing showed that LS-102 spiked into dog plasma was stable for 4 h at room temperature, for up to 2 weeks at -80 °C, and during three freeze-thaw cycles. The method was effectively and successfully applied to the pharmacokinetics of LS-102 after oral administration (5, 10 and 20 mg/kg) to beagle dogs. Peak plasma concentrations are attained within approximately 2 h after oral administration with a half-life ranging from 1.55 h to 4.49 h. The plasma concentration-time curve of LS-102 after oral administration presents the phenomenon of a double-peak absorption phase. The peak concentration and area under the concentration-time curve of LS-102 seemed to increase with the increasing doses proportionally, that suggesting linear pharmacokinetics in dogs. Meanwhile, the doxorubicin (Dox)-injured H9c2 cell model was prepared by incubating the cells in 1 µM Dox for 24 h. MTT assay and LDH release measurement showed that LS-102 protected against Dox-induced cardiomyocyte death. CONCLUSION The obtained results may help to guide the further pre-clinical research of LS-102 as a potentially novel cardioprotective agent.

Abstract
The diaphragmatic fatigue that results from airflow obstruction is associated with the severe morbidity of patients with chronic obstructive pulmonary disease. Astragaloside IV (AS-IV) has antioxidant, anti-apoptotic and anti-inflammatory activities in various cell types. The present study aimed to evaluate the protective effects of AS-IV in diaphragmatic muscle cells. Diaphragmatic muscle cells extracted from neonatal rats were treated with a series of AS-IV concentrations (5, 10 or 20 mg/l) and the AKT inhibitor GSK690693 in the presence of interleukin-8 (IL-8). Cell proliferation and AKT phosphorylation were measured using Cell Counting Kit-8 and western blot assays, respectively. Cell apoptosis and reactive oxygen species (ROS) production were evaluated using flow cytometric analysis. Caspase activity and concentrations of proinflammatory factors (tumor necrosis factor-α, IL-6 and IL-8) were assessed using a caspase colorimetric assay and ELISA, respectively. IL-8 treatment resulted in decreased rates of cell proliferation and increased rates of AKT phosphorylation, cell apoptosis, caspase 3/9 activity, ROS production and proinflammatory factor production. AS-IV and GSK690693 treatment reversed the effects of IL-8. The effects of AS-IV were dose-dependent. The present results suggested that AS-IV is a candidate for the treatment of diaphragmatic fatigue due to its antioxidant, anti-apoptotic and anti-inflammatory activity.

Abstract
Objective: Insulin resistance (IR) is a risk factor for non-alcoholic fatty liver disease (NAFLD), which is characterized by lipid accumulation in hepatocytes. AMP-activated protein kinase (AMPK)-induced sterol regulatory element binding protein-1c (SREBP-1c) phosphorylation is crucial for proper regulation of lipid metabolism in the liver. Astragaloside IV (AST-IV) was found to decrease lipid accumulation in hepatocytes by activating AMPK, which is required to regulate lipid metabolism in liver tissue by inducing SREBP-1c phosphorylation. Method: To evaluate the direct effect of AST on lipid accumulation in hepatocytes with IR and elucidate the underlying mechanisms, we induced IR in HepG2 cells, and used compound C and 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside (AICAR) (an AMPK inhibitor and agonist, respectively) as control substances. We evaluated glucose, triglyceride (TG), and non-esterified fatty acid (NEFA) production, as well as SREBP-1c transcription, SREBP-1c protein expression, and downstream gene expression with or without the presence of AST. We also investigated whether phosphorylation of SREBP-1c at Ser372 was required for AST function. Results: We found that AST attenuated IR and lipid accumulation in HepG2 cells. As an AMPK activator, AST promoted gene expression and activation of AMPK by increasing phosphorylation of AMPKa. AST also inhibited translocation of SREBP-1c into the nucleus of insulin-resistant HepG2 cells by inducing phosphorylation of SREBP-1c at Ser372. Conclusion: This study demonstrated that AST attenuates IR and lipid accumulation in HepG2 cells by regulating AMPK-dependent phosphorylation of SREBP-1c at Ser372, suggesting AST as a promising drug for treating hepatic steatosis.

Abstract
AIMS Astragaloside IV (AS-IV) is the central active component extracted from Radix astragali, an herbal remedy widely used in traditional Chinese medicine for the treatment of cardiovascular diseases. Aberrant proliferation of vascular smooth muscle cells (VSMCs) is closely involved in the initiation and progression of cardiovascular complications, such as atherosclerosis. Here we investigated whether AS-IV inhibited agonist-induced vascular smooth muscle cells (VSMCs) proliferation and the underlying mechanism. MAIN METHODS Quiescent cultured A10 cells (adult rat VSMCs) were treated with Angiotensin II (AngII) or AngII plus AS-IV for 48 h. The growth rate of A10 cells was analyzed by CCK8 assay. RT-PCR analysis was carried out to examine the expression of α-smooth muscle actin (α-SMA), an important phenotypic modulation marker. In addition, whether the interference of AS-IV on AngII-mediated growth of VSMCs via regulation of cell cycle was evaluated by flow cytometry. In order to explore the role of cell cycle machinery, we measured kinase activity of CDK2 by Kinase assay and the protein level of Cdc25 by western blot, respectively. KEY FINDINGS These data suggested that AS-IV exerted beneficial effects on AngII -induced abnormal growth in rat VSMCs through disturbing cell cycle, especially block G1/S transition by attenuating CDK2 activity, which may hinder the process of pathological vascular remodeling during atherosclerosis.

Abstract
This study was designed to examine the expression of hypoxia-inducible factor-1α (HIF-1α) and the level and activity of endothelial nitric oxide synthase (eNOS) in the hearts and livers of mice exposed to hypergravity. Hypergravity-induced hypoxia and the subsequent post-exposure reoxygenation significantly increased cardiac HIF-1α levels. Furthermore, the levels and activity of cardiac eNOS also showed significant increase immediately following hypergravity exposure and during the reoxygenation period. In contrast, the expression of phosphorylated Akt (p-Akt) and phosphorylated extracellular signal-regulated kinase (p-ERK) showed significant elevation only during the reoxygenation period. These data raise the possibility that the increase in cardiac HIF-1α expression induced by reoxygenation involves a cascade of signaling events, including activation of the Akt and ERK pathways. In the liver, HIF-1α expression was significantly increased immediately after hypergravity exposure, indicating that hypergravity exposure to causes hepatocellular hypoxia. The hypergravity-exposed livers showed significantly higher eNOS immunoreactivity than did those of control mice. Consistent with these results, significant increases in eNOS activity and nitrate/nitrite levels were also observed. These findings suggest that hypergravity-induced hypoxia plays a significant role in the upregulation of hepatic eNOS.

Abstract
BACKGROUND Astragalus genus includes most of the common, historical herbal medicines that have various applications in Asian countries. However, clinical data and mechanistic insights into their actions are still lacking. PURPOSE In this study, we aimed to examine the effects of astragalosides on wound healing in vitro and in vivo, as well as the underlying mechanisms of these actions. METHODS The wound healing activity of astragalosides was investigated in human HaCaT keratinocytes, human dermal fibroblast (HDF) cells, and murine models of wound healing. RESULTS All eight astragalosides studied enhanced epidermal growth factor receptor (EGFR) activity in HaCaT cells. Among them, astragaloside VI (AS-VI) showed the strongest EGFR activation. Consistently, AS-VI and cycloastragenol-6-O-beta-D-glucoside (CMG), which is the major metabolite of astragalosides, enhanced extracellular signal-regulated kinase (ERK) activity in a concentration-dependent manner. In agreement, both compounds induced EGFR-dependent cell proliferation and migration in HaCaT and HDF cells. In addition, we showed that AS-VI and CMG accelerated the healing of both sterile and infected wounds in vivo. These effects were associated with increased angiogenesis in the scar tissue. CONCLUSION AS-VI and CMG increased the proliferation and migration of skin cells via activation of the EGFR/ERK signalling pathway, resulting in the improvement of wound healing in vitro and in vivo. These findings indicate the therapeutic potential of AS-VI and CMG to accelerate wound healing; additionally, they suggest the mechanistic basis of this activity.

Abstract
Cardiac microvascular endothelial cells (CMECs) are important angiogenic components and are injured rapidly after cardiac ischaemia and anoxia. Cardioprotective effects of Qiliqiangxin (QL), a traditional Chinese medicine, have been displayed recently. This study aims to investigate whether QL could protect CMECs against anoxic injury and to explore related signalling mechanisms. CMECs were successfully cultured from Sprague‐Dawley rats and exposed to anoxia for 12 hrs in the absence and presence of QL. Cell migration assay and capillary‐like tube formation assay on Matrigel were performed, and cell apoptosis was determined by TUNEL assay and caspase‐3 activity. Neuregulin‐1 (NRG‐1) siRNA and LY294002 were administrated to block NRG‐1/ErbB and PI3K/Akt signalling, respectively. As a result, anoxia inhibited cell migration, capillary‐like tube formation and angiogenesis, and increased cell apoptosis. QL significantly reversed these anoxia‐induced injuries and up‐regulated expressions of NRG‐1, phospho‐ErbB2, phospho‐ErbB4, phospho‐Akt, phospho‐mammalian target of rapamycin (mTOR), hypoxia‐inducible factor‐1α (HIF‐1α) and vascular endothelial growth factor (VEGF) in CMECs, while NRG‐1 knockdown abolished the protective effects of QL with suppressed NRG‐1, phospho‐ErbB2, phospho‐ErbB4, phospho‐Akt, phospho‐mTOR, HIF‐1α and VEGF expressions. Similarly, LY294002 interrupted the beneficial effects of QL with down‐regulated phospho‐Akt, phospho‐mTOR, HIF‐1α and VEGF expressions. However, it had no impact on NRG‐1/ErbB signalling. Our data indicated that QL could attenuate anoxia‐induced injuries in CMECs via NRG‐1/ErbB signalling which was most probably dependent on PI3K/Akt/mTOR pathway.

Abstract
Astragaloside IV (AST-IV) is a principal component of Radix Astragali seu Hedysari (Huangqi) and exerts potential neuroprotection in experimental ischemic stroke. Here, we systematically assessed the effectiveness and possible mechanisms of AST-IV for experimental acute ischemic stroke. An electronic search in eight databases was conducted from inception to March 2016. The study quality score was evaluated using the CAMARADES. Rev Man 5.0 software was used for data analyses. Thirteen studies with 244 animals were identified. The study quality score of included studies ranged from 3/10 to 8/10. Eleven studies showed significant effects of AST-IV for ameliorating the neurological function score (P < 0.05); seven studies for reducing the infarct volume (P < 0.05); and three or two studies for reducing the brain water content and Evans blue leakage (P < 0.05), respectively, compared with the control. The mechanisms of AST-IV for ischemic stroke are multiple such as antioxidative/nitration stress reaction, anti-inflammatory, and antiapoptosis. In conclusion, the findings of present study indicated that AST-IV could improve neurological deficits and infarct volume and reduce the blood-brain barrier permeability in experimental cerebral ischemia despite some methodological flaws. Thus, AST-IV exerted a possible neuroprotective effect during the cerebral ischemia/reperfusion injury largely through its antioxidant, anti-inflammatory, and antiapoptosis properties.

Abstract
Pulmonary arterial hypertension (PAH) is characterized by endothelial dysfunction and structural remodeling of the pulmonary vasculature, mediated initially by reduced oxygen availability in the lungs. Hypoxia inducible factor (HIF), consisting of the functional subunit, HIF‑1α, and the constitutively expressed HIF‑1β, is involved in the pathological processes associated with hypoxia. In the current study, the sequences of cDNAs and amino acids of HIF were characterized and analyzed using online bioinformatics tools. To further evaluate whether HIF accounts for the occurrence of PAH, the present study determine the expression and phosphorylation levels of HIF and its associated pathways, including extracellular signal‑regulated kinase (Erk)1/2 and phosphoinositide 3‑kinase (PI3K)/Akt, in the lungs of patients with PAH by reverse transcription‑quantitative polymerase chain reaction and western blotting. The mRNA expression levels of PI3K, Erk2, and HIF‑1α in the patients with PAH were significantly higher, compared with those in the control group, by 3.6‑fold (P<0.01), 4.06‑fold and 2.64‑fold (P<0.05), respectively. No significant differences were found in the mRNA and protein levels of Akt between the two groups (P>0.05). The protein levels of phosphorylated (p‑)Akt, Erk1/2, p‑Erk1/2, HIF‑1α and HIF‑1β were significantly increased by 5.89‑, 0.5‑, 0.59‑, 1.46‑ and 0.92‑fold, respectively, in the patients with PAH, compared with those in the controls group (P<0.01 for p‑Akt, Erk1/2; P<0.05 for p‑Erk1/2, HIF‑1α and HIF‑1β). These findings suggested that the mitogen‑activated protein kinase and PI3K/Akt signaling pathways, and HIF‑1 may perform a specific function in the pathogenesis of PAH.

Abstract
Astragaloside IV (AS-IV), one of the major active compounds extracted from Astragali Radix, has been used experimentally for its potent antiinflammatory and immunoregulatory activities. In this study, we further investigate the potential efficacy of AS-IV on impaired wound healing in streptozotocin-induced diabetic mice. A full-thickness skin wound was produced on the back of diabetic mice and treated with AS-IV or vehicle topically. Our results showed that AS-IV application promoted diabetic wound repair with wounds gaping narrower and exhibiting augmented reepithelialization. AS-IV enhanced the collagen deposition and the expression of extracellular matrix (ECM)-related genes such as fibronectin and collagen IIIa, which implies a direct effect of AS-IV on matrix synthesis. AS-IV also improved the new blood vessel formation in wound tissue with increased numbers of endothelial cells and enhanced expression of VEGF and vWF. Moreover, the beneficial effect of AS-IV was related to the development of polarized alternatively activated macrophages, which involved in resolution of inflammation and facilitation of wound repair. All together, these findings suggest that AS-IV may play a potential effect on maintenance of cutaneous homeostasis and acceleration of diabetic wound healing.

Abstract
Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal
peptide (VIP) through the binding of vasoactive intestinal peptide receptors (VIPRs),
perform a wide variety of effects in human cancers, including glioblastoma multiforme
(GBM). This tumor is characterized by extensive areas of hypoxia, which triggers the
expression of hypoxia-inducible factors (HIFs). HIFs not only mediate angiogenesis
but also tumor cell migration and invasion. Furthermore, HIFs activation is linked to
epidermal growth factor receptor (EGFR) overexpression. Previous studies have shown
that VIP interferes with the invasive nature of gliomas by regulating cell migration.
However, the role of VIP family members in GBM infiltration under low oxygen tension
has not been clarified yet. Therefore, in the present study we have investigated, for
the first time, the molecular mechanisms involved in the anti-invasive effect of
PACAP or VIP in U87MG glioblastoma cells exposed to hypoxia induced by treatment with
desferrioxamine (DFX). The results suggest that either PACAP or VIP exert an
anti-infiltrative effect under low oxygen tension by modulating HIFs and EGFR
expression, key elements involved in cell migration and angiogenesis. These peptides
act through the inhibition of PI3K/Akt and MAPK/ERK signaling pathways, which are
known to have a crucial role in HIFs regulation.

Qi-Shen-Yi-Qi Dripping Pills Promote Angiogenesis of Ischemic Cardiac Microvascular Endothelial Cells by Regulating MicroRNA-223-3p Expression. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:5057328. [PMID: 27057198 PMCID: PMC4761670 DOI: 10.1155/2016/5057328] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/30/2015] [Revised: 11/10/2015] [Accepted: 12/01/2015] [Indexed: 01/20/2023]
Abstract
Traditional Chinese medicine (TCM) research shows that Qi-Shen-Yi-Qi Dripping Pills (QSYQ) can promote ischemic cardiac angiogenesis. Studies have shown that microRNAs (miRNAs) are the key component of gene regulation networks, which play a vital role in angiogenesis and cardiovascular disease. Mechanisms involving miRNA by which TCM promotes ischemic cardiac angiogenesis have not been reported. We found that microRNA-223-3p (mir-223-3p) was the core miRNA of angiogenesis of rats ischemic cardiac microvascular endothelial cells (CMECs) and inhibited angiogenesis by affecting RPS6KB1/HIF-1α signal pathway in previous study. Based on the results, we observed biological characteristics and optimal dosage for QSYQ intervening in rats ischemic CMECs angiogenesis and concluded that QSYQ low-dose group had the strongest ability to promote angiogenesis of ischemic myocardium. Using miRNA chip and real-time PCR techniques in this study, we identified mir-223-3p as the pivotal miRNA in QSYQ that regulated angiogenesis of ischemic CMECs. From real-time PCR and western blot analysis, research showed that gene and protein expression of factors located RPS6KB1/HIF-1α signaling pathway, including HIF-1α, VEGF, MAPK, PI3K, and AKT, were significantly upregulated by QSYQ to regulate angiogenesis of ischemic CMECs. This study showed that QSYQ promote ischemic cardiac angiogenesis by downregulating mir-223-3p expression in rats ischemic CMECs.

Protective effect of Astragalus polysaccharide on endothelial progenitor cells injured by thrombin. Int J Biol Macromol 2015; 82:711-8.

Abstract
Several studies have demonstrated that Astragalus polysaccharide (APS) has a protective effect on endothelial cells damaged by various factors. To examine the role of APS in the endothelial inflammatory response, rat bone marrow endothelial progenitor cells (EPCs) were isolated by density gradient centrifugation and identified by immunohistochemistry, then we established a model of inflammatory injury induced by thrombin and measured the effects of APS on EPC viability and proliferation by MTT assays. We also assayed the effect APS had on the inflammatory response, by examining the nuclear factor kappa B (NF-κB) signaling pathway, as well as the expression of intercellular adhesion molecule-1 (ICAM-1), vascular endothelial growth factor (VEGF) and its receptors Flt-1 and KDR. Results demonstrated that EPCs were damaged by thrombin, and APS appeared to inhibit this damage. APS suppressed thrombin-induced ICAM-1 expression by blocking NF-κB signaling in rat bone marrow EPCs, and up-regulating expression of VEGF and its receptors. We believed that APS may be used to treat and prevent EPC injury-related diseases.

Abstract
The aim of the present study was to evaluate the effect of astragalosides (ASTs) on angiogenesis, as well as the expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) following myocardial infarction (MI). MI was induced in rats by ligation of the left coronary artery. Twenty-four hours after surgery, the rats were divided into low-dose, high-dose, control and sham surgery groups (n=8 per group). The low- and high-dose groups were treated with ASTs (2.5 and 10 mg/kg/day, respectively, via intraperitoneal injection), while, the control and sham surgery group rats received saline. Serum levels, and mRNA and protein expression levels of VEGF and bFGF, as well as the microvessel density (MVD) were determined four weeks post-treatment. Twenty-four hours post-surgery, VEGF and bFGF serum levels were observed to be comparable between the groups; while at four weeks, the VEGF and bFGF levels were higher in the AST-treated rats (P<0.01). Similarly, VEGF and bFGF mRNA and protein expression levels were higher following AST treatment (P<0.05). No difference in VEGF mRNA expression between the low- and high-dose groups was noted, however, an increase in the bFGF expression levels was detected in the high-dose group. Newly generated blood vessels were observed following MI, with a significant increase in MVD observed in the AST-treated groups (P<0.05). AST promotes angiogenesis of the heart and increases VEGF and bFGF expression levels. Thus, it is hypothesized that increased VEGF and bFGF levels may contribute to the AST-induced increase in angiogenesis in rat models of MI.

Altern Ther Health Med 2015; 15:261. [PMID: 26231491 PMCID: PMC4522129 DOI: 10.1186/s12906-015-0776-3] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2015] [Accepted: 07/13/2015] [Indexed: 12/14/2022]
Abstract
BACKGROUND Astragalus membranaceus (AM) is a Chinese traditional herb which has been reported to have broad positive effects on many diseases, including hepatitis, heart disease, diabetes and skin disease. AM can promote cell proliferation, increase the activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx), and inhibit apoptosis by regulating the transcription of proto-oncogenes controlling cell death. While AM is included in some commercially available "testosterone boosting supplements", studies directly testing ability of AM to modulate testosterone production are lacking. In the present study, we examined the effects of AM on Leydig cell function in vitro. METHODS Rat Leydig cells were purified and treated with AM at different concentrations (0 μg/mL, 10 μg/mL, 20 μg/mL, 50 μg/mL, 100 μg/mL and 150 μg/mL) and cell counting-8 (CCK-8) assay, Enzyme-linked immunosorbent assay, quantitative real time PCR and analysis of activities of SOD and GPx were done respectively. RESULTS Treatment with 100 μg/mL (P<0.05) and 150 μg/mL AM (P<0.01) significantly increased Leydig cell numbers. Treatment with AM (20 μg/mL, 50 μg/mL and 100 μg/mL) significantly increased testosterone production (P<0.01). In addition, increased Leydig cell SOD and GPx activities were observed in response to 20 μg/mL and 50 μg/mL AM treatment (P<0.01). Furthermore, expression of Bax mRNA was significantly decreased (P<0.01), and the ratio of Bcl-2/Bax mRNA was significantly increased in response to 20 μg/mL AM in the culture medium (P<0.05). CONCLUSIONS Results supported a beneficial effect of AM on multiple aspects of rat Leydig cell function in vitro including testosterone production.

The protective effect of astragaloside IV against benzo[a]pyrene induced endothelial progenitor cell dysfunction. Life Sci 2015; 132:13-9. [PMID: 25916804 DOI: 10.1016/j.lfs.2015.04.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2015] [Revised: 03/08/2015] [Accepted: 04/07/2015] [Indexed: 01/10/2023]
Abstract
AIMS Benzo[a]pyrene (BaP), a prominent component of tobacco, has been revealed to induce damage to endothelial progenitor cells (EPCs). Astragaloside IV (AS-IV) is widely used for the treatment of cardiovascular diseases in China. In this study, we evaluated the effects of AS-IV on the function of human EPCs after BaP exposure and explored the underlying mechanism. MATERIALS AND METHODS Human umbilical cord blood mononuclear cells were isolated using density gradient centrifugation. Cells of the 4th passage were randomly divided into 6 groups. EPCs of experimental groups were pre-treated with different concentrations (2, 10 and 50 μg/mL) of AS-IV for 2h before exposure to BaP (20 μM) for 24h. The proliferation, migration, and adhesion of the treated EPCs were evaluated using a cell counting kit-8, Transwell assay and adhesion assay respectively. Interleukin-1β, tumor necrosis factor-α, malondialdehyde and SOD contents in the supernatant were evaluated. The expression of RAGE protein was measured by Western blotting. KEY FINDINGS The results demonstrated that AS-IV pre-treatment significantly improved BaP-induced dysfunction of EPCs in terms of proliferation, migration and adhesion. Furthermore, AS-IV reduced the production of reactive oxygen species, malondialdehyde, interleukin-1β and tumor necrosis factor-α of the BaP-treated EPCs. Finally AS-IV pre-treated EPCs showed an increased SOD activity and decreased RAGE protein expression. SIGNIFICANCE AS-IV is able to prevent BaP-mediated EPC dysfunction by at least inhibiting oxidative stress through the RAGE pathway.
