Abstract
African swine fever (ASF) is a highly infectious disease caused by the African swine fever virus (ASFV) in swine. It is characterized by the death of cells in infected tissues. However, the molecular mechanism of ASFV-induced cell death in porcine alveolar macrophages (PAMs) remains largely unknown. In this study, transcriptome sequencing of ASFV-infected PAMs found that ASFV activated the JAK2-STAT3 pathway in the early stages and apoptosis in the late stages of infection. Meanwhile, the JAK2-STAT3 pathway was confirmed to be essential for ASFV replication. AG490 and andrographolide (AND) inhibited the JAK2-STAT3 pathway, promoted ASFV-induced apoptosis, and exerted antiviral effects. Additionally, CD2v promoted STAT3 transcription and phosphorylation as well as translocation into the nucleus. CD2v is the main envelope glycoprotein of the ASFV, and further investigations showed that CD2v deletion downregulates the JAK2-STAT3 pathway and promotes apoptosis to inhibit ASFV replication. Furthermore, we discovered that CD2v interacts with CSF2RA, which is a hematopoietic receptor superfamily member in myeloid cells and a key receptor protein that activates receptor-associated JAK and STAT proteins. In this study, CSF2RA small interfering RNA (siRNA) downregulated the JAK2-STAT3 pathway and promoted apoptosis to inhibit ASFV replication. Taken together, ASFV replication requires the JAK2-STAT3 pathway, while CD2v interacts with CSF2RA to regulate the JAK2-STAT3 pathway and inhibit apoptosis to facilitate virus replication. These results provide a theoretical basis for the escape mechanism and pathogenesis of ASFV. IMPORTANCE African swine fever is a hemorrhagic disease caused by the African swine fever virus (ASFV), which infects pigs of different breeds and ages, with a fatality rate of up to 100%. It is one of the key diseases affecting the global livestock industry. Currently, no commercial vaccines or antiviral drugs are available. Here, we show that ASFV replicates via the JAK2-STAT3 pathway. More specifically, ASFV CD2v interacts with CSF2RA to activate the JAK2-STAT3 pathway and inhibit apoptosis, thereby maintaining the survival of infected cells and promoting viral replication. This study revealed an important implication of the JAK2-STAT3 pathway in ASFV infection and identified a novel mechanism by which CD2v has evolved to interact with CSF2RA and maintain JAK2-STAT3 pathway activation to inhibit apoptosis, thus elucidating new information regarding the signal reprogramming of host cells by ASFV.

Abstract
Autophagy plays various roles at different stages of ischemia reperfusion (I/R) injury in cardiomyocytes. It has been reported that tissue factor pathway inhibitor (TFPI) has a protective effect on I/R injury. This study aimed to determine the roles of TFPI in autophagy during the I/R injury process in cardiomyocytes and the possible mechanisms. An isolated hypoxia/reoxygenation (H/R) pattern of cardiomyocytes was established by the MIC101 system. The cell viability and oxidative stress of cardiomyocytes were detected by an MTT assay and ROS assay, respectively. The autophagy level was measured by Ad-mCherry-GFP-LC3B and MDC. We detected the expression levels of autophagy-related proteins by western blotting. After 2 h of hypoxia and 12 h of reoxygenation, the cardiomyocyte viability in the H/R group was significantly lower than that in the control group (p < 0.05) than in the H/R group. According to intracellular ROS production, the fluorescence intensity in the H/R group was enhanced compared with that in the negative control group, and it was weaker in the H/R + rTFPI group compared with the H/R group. The level of autophagy and the expression levels of autophagy-related proteins (LC3-II/LC3-I, Beclin-1 and PI3K) were markedly increased in the H/R group compared to the control group (p < 0.05) whereas the levels were markedly decreased in the H/R + rTFPI group compared to the H/R group (p < 0.05). TFPI could relieve cardiomyocyte injury by inhibiting the Class III PI3K/Beclin-1 pathway and oxidative stress; thus, TFPI decreased autophagy and protected cardiomyocytes induced by H/R injury. In conclusion, TFPI may be a new direction for the prevention of myocardial I/R injury.

Abstract
BACKGROUND Cancer Stem Cells (CSCs) play an important role in various stages of cancer development, advancement, and therapy resistance. Ketoprofen-RGD has been revealed to act as an anti-cancer agent against some tumors. OBJECTIVE We aimed to explore the effects of a novel Ketoprofen-RGD compound on the suppression of Breast Cancer Stem-like Cells (BCSCs) and their parental cells. METHODS Mammospheres were developed from MCF-7 cells and assessed by CSC surface markers through flowcytometry. The anti-proliferative and pro-apoptotic activities of Ketoprofen-RGD were measured by MTS assay and flowcytometry. The expression levels of stemness markers and JAK2/STAT proteins were measured by quantitative Real Time-PCR (qRT-PCR) and western blotting, respectively. Intracellular Reactive Oxygen Species (ROS) was measured using a cell permeable, oxidant-sensitive fluorescence probe (carboxy-H2DCFDA). RESULTS Ketoprofen-RGD significantly reduced the mammosphere formation rate and the expression of three out of six stemness markers and remarkably decreased viability and induced apoptosis of spheroidal and parental cells compared to controls. Further experiments using CD95L, as a death ligand, and ZB4 antibody, as an extrinsic apoptotic pathway blocker, showed that Ketoprofen-RGD induced intrinsic pathway, suggesting a mechanism by which Ketoprofen-RGD triggers apoptosis. ROS production was also another way to induce apoptosis. Results of western blot analysis also revealed a marked diminish in the phosphorylation of JAK2 and STAT proteins. CONCLUSION Our study, for the first time, elucidated an anti-BCSC activity for Ketoprofen-RGD via declining stemness markers, inducing toxicity, and apoptosis in these cells and parental cells. These findings may suggest this compound as a promising anti-breast cancer.

Abstract
Chemokines may promote the formation and instability of atherosclerotic plaque, which is the most common cause of acute coronary syndrome. The aim of this study was to clarify the function of monocyte chemotactic protein-3 (MCP-3) in the stability of atherosclerotic plaque, to determine the role of tissue factor pathway inhibitor (TFPI) on the development and stability of atherosclerotic plaques, and to further elucidate the anti-atherosclerotic mechanism of TFPI with the emphasis on chemokine MCP-3. We constructed an adenovirus-mediated shRNA against mouse MCP-3 (Ad-MCP-3-shRNA) and an adenovirus-containing TFPI (Ad-TFPI), and tranferred them in a model of vulnerable plaque in ApoE-/- mice respectively. Here, we reported that MCP-3-shRNA and TFPI could both reduce the plaque area and decrease the content of lipids and macrophages, on the contrary, the fibrous cap thickness and content of collagen and smooth muscle cells were increased. In addition, the expression of MCP-3 and CC chemokine receptor 2 (CCR2) was decreased by TFPI transfer. These data provide the first in vivo evidence that MCP-3 is a major contributor to the unstability of atherosclerotic plaque and TFPI may exert its anti-atherosclerotic effects and promote stabilisation of plaque at least partly through inhibiting MCP-3/CCR2 pathway, which may be a new therapeutic method for atherosclerosis.

Abstract
The migration, dedifferentiation, and proliferation of vascular smooth muscle cells (VSMCs) are responsible for intimal hyperplasia, but the mechanism of this process has not been elucidated. WD repeat domain 1 (WDR1) promotes actin-depolymerizing factor (ADF)/cofilin-mediated depolymerization of actin filaments (F-actin). The role of WDR1 in neointima formation and progression is still unknown. A model of intimal thickening was constructed by ligating the left common carotid artery in Wdr1 deletion mice, and H&E staining showed that Wdr1 deficiency significantly inhibits neointima formation. We also report that STAT3 promotes the proliferation and migration of VSMCs by directly promoting WDR1 transcription. Mechanistically, we clarified that WDR1 promotes the proliferation and migration of VSMCs and neointima formation is regulated by the activation of the JAK2/STAT3/WDR1 axis.

Abstract
Endothelium (EC) dysfunction plays an important role in vascular diseases, such as arteriosclerosis and hypoxia/reoxygenation (H/R) injury. Tissue factor pathway inhibitor (TFPI) is the only physiological inhibitor of the TF/FVIIa complex in vivo. This experiment aimed to determine the effect of TFPIα on H/R-induced EC injury and the possible mechanisms. The MIC101 hypoxia system was used to establish an EC H/R injury model in vitro. Our results showed that 6 h after reoxygenation, the EC injury in H/R group was higher than that in the control group, whereas after adding TFPIα, the EC injury was alleviate than that in H/R group. The level of ROS was higher in the H/R group than in the control group, while it was apparently lower in the H/R+TFPIα group than in the H/R group. After H/R, the number of autophagosomes and the autophagic flux were significantly increased, whereas TFPIα could decrease the autophagy level after H/R. The expressions of LC3-II/LC3-I, Beclin-1 and PI3K were obviously higher after H/R and lower after adding TFPIα. In conclusion, autophagy contributes to EC injury during the H/R period. TFPIα could decrease autophagy in ECs, and the mechanism might be class III PI3K/Beclin-1 pathway regulation.

J Cell Mol Med 2019; 23:7246-7260.

Abstract
Emerging evidence indicates that fibroblast‐specific protein 1 (FSP1) provides vital effects in cell biofunctions. However, whether FSP1 influences the adventitial fibroblast (AF) and vascular remodelling remains unclear. Therefore, we investigated the potential role and action mechanism of FSP1‐mediated AF bioactivity. AFs were cultured and stimulated with FSP1 and siRNA‐FSP1 in vitro. Viability assays demonstrated that siRNA‐FSP1 counteracted AFs proliferative, migratory and adherent abilities enhanced with FSP1. Flow cytometry revealed that FSP1 increased AFs number in S phase and decreased cellular apoptosis. Contrarily, siRNA‐FSP1 displayed the contrary results. RT‐PCR, Western blotting and immunocytochemistry showed that FSP1 synchronously up‐regulated the expression of molecules in RAGE, JAK2/STAT3 and Wnt3a/β‐catenin pathways and induced a proinflammatory cytokine profile characterized by high levels of MCP‐1, ICAM‐1 and VCAM‐1. Conversely, FSP1 knockdown reduced the expression of these molecules and cytokines. The increased number of autophagosomes in FSP1‐stimulated group and fewer autophagic corpuscles in siRNA‐FSP1 group was observed by transmission electron microscope (TEM). Autophagy‐related proteins (LC3B, beclin‐1 and Apg7) were higher in FSP1 group than those in other groups. Conversely, the expression of p62 protein was shown an opposite trend of variation. Therefore, these pathways can promote AFs bioactivity, facilitate autophagy and induce the expression of the proinflammatory cytokines. Contrarily, siRNA‐FSP1 intercepts the crosstalk of these pathways, suppresses AF functions, restrains autophagy and attenuates the expression of the inflammatory factors. Our findings indicate that crosstalk among RAGE, STAT3/JAK2 and Wnt3a/β‐catenin signalling pathways may account for the mechanism of AF functions with the stimulation of FSP1.

Abstract
Tissue factor pathway inhibitor (TFPI) reduces the development of atherosclerosis by regulating tissue factor (TF) mediated coagulation pathway. In this review, we focus on recent findings on the inhibitory effects of TFPI on endothelial cell activation, vascular smooth muscle cell (VSMC) proliferation and migration, inflammatory cell recruitment and extracellular matrix which are associated with the development of atherosclerosis. Meanwhile, we are also concerned about the impact of TFPI levels and genetic polymorphisms on clinical atherogenesis. This article aims to explain the mechanism in inhibiting the development of atherosclerosis and clinical effects of TFPI, and provide new ideas for the clinical researches and mechanism studies of atherothrombosis.

Cortistatin inhibits arterial calcification in rats via GSK3β/β-catenin and protein kinase C signalling but not c-Jun N-terminal kinase signalling. Acta Physiol (Oxf) 2018; 223:e13055. [PMID: 29436118 DOI: 10.1111/apha.13055] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2017] [Revised: 02/06/2018] [Accepted: 02/07/2018] [Indexed: 12/27/2022]
Abstract
AIM Cortistatin (CST) is a newly discovered endogenous active peptide that exerts protective effects on the cardiovascular system. However, the relationship between CST and aortic calcification and the underlying mechanism remain obscure. Therefore, we investigated effects of CST on aortic calcification and its signalling pathways. METHODS Calcium content and alkaline phosphatase (ALP) activity were measured using the o-cresolphthalein colorimetric method and ALP assay kit respectively. Protein expression of smooth muscle (SM)-ɑ-actin, osteocalcin (OCN), β-catenin, glycogen synthase kinase 3β (GSK3β), p-GSK3β, protein kinase C (PKC), p-PKC, c-Jun N-terminal kinase (JNK) and p-JNK was determined using Western blotting. RESULTS In aorta from a rat vitamin D3 calcification model, CST abrogated calcium deposition and pathological damage, decreased the protein expression of OCN and β-catenin and increased SM-ɑ-actin expression. In a rat cultured vascular smooth muscular cell (VSMC) calcification model induced by β-glycerophosphate (β-GP), CST inhibited the increase in ALP activity, calcium content and OCN protein and the decrease in SM-α-actin expression. CST also inhibited the β-GP-induced increase in p-GSK3β and β-catenin protein (both P < .05). The inhibitory effects of CST on ALP activity, calcium deposition and β-catenin protein were abolished by pretreatment with lithium chloride, a GSK3β inhibitor. CST promoted the protein expression of p-PKC by 68.5% (P < .01), but not p-JNK. The ability of CST to attenuate β-GP-induced increase in ALP activity, calcium content and OCN expression in the VSMC model was abolished by pretreatment with the PKC inhibitor Go6976. CONCLUSION These results indicate that CST inhibits aortic calcification and osteogenic differentiation of VSMCs likely via the GSK3β/β-catenin and PKC signalling pathways, but not JNK signalling pathway.

Abstract
Increased vascular smooth muscle cell (VSMC) proliferation substantially contributes to the pathogenesis of atherosclerosis and intimal hyperplasia after vascular injury. The importance of inflammation in VSMC proliferation is now being recognized. Preventing the inflammatory response is one therapeutic strategy that can be used to inhibit atherosclerosis in the clinic. The present study, using RNA interference and gene transfer techniques, was conducted to investigate the effect of monocyte chemotactic protein-3 (MCP-3) on VSMC proliferation that is a result of TNF-α stimulation, and whether overexpression of the tissue factor pathway inhibitor (TFPI) gene could prevent VSMC proliferation by blocking the MCP-3/CC chemokine receptor 2 (CCR2) pathway. Mouse VSMCs were infected in vitro with recombinant adenoviruses containing either mouse MCP-3-shRNA (Ad-MCP-3-shRNA), the TFPI gene (Ad-TFPI), or the negative control, which was shRNA encoding the sequence for EGFP (Ad-EGFP) or DMEM only. The cells were then stimulated with TNF-α for different time periods on the third day after gene transfer. The data show that VSMC proliferation in the Ad-MCP-3-shRNA and Ad-TFPI groups was markedly decreased using BrdU ELISA and MTT assays; MCP-3-shRNA and TFPI inhibited the expression of MCP-3 and CCR2 after long-term stimulation and inhibited the phosphorylation of ERK1/2 and AKT after short-term stimulation, as shown by ELISA and western blot analysis. This study provides convincing evidence that clarifies the effect of the proinflammatory factor MCP-3 in promoting VSMC proliferation. Our data also show, for the first time, that TFPI has an anti-proliferative role in TNF-α stimulated-VSMCs at least partly by interfering with the MCP-3/CCR2 pathway and then via suppression of the ERK1/2 and PI3K/AKT signaling pathways. We conclude that TFPI gene transfer may be a safe and effective therapeutic tool for treating atherosclerosis and intimal hyperplasia.

Abstract
INTRODUCTION Our aim was to study the efficacy and safety of tissue factor pathway inhibitor (TFPI)-coated stents in inhibiting restenosis in a rabbit carotid artery model. METHODS Subculture was conducted in aorta smooth muscle cell, which was taken from male Wistar rat, and the 3-5-generation cells were taken for plasmid transfection and cytotoxicity experiment. TFPI microspheres were made of a TFPI plasmid which was enwrapped by poly-l-glutamic acid (PLGA). TFPI-coated stents (n = 7) and bare metal stents (n = 6) were implanted into prepared carotid artery stenosis model of New Zealand white rabbits. The transfection efficiency of TFPI gene and its influence on animal tissue, restenosis inhibition, and biochemical indicator were observed. RESULT Tissue factor pathway inhibitor microspheres can transfect successfully into cells, and present no cytotoxicity. Autopsy results showed no pathological changes in liver and spleen of rabbits after implanting TFPI-coated stents. TFPI gene could transfect and express successfully in vessel wall cells, and thrombus was found in some lumens of bare metal stents group after 7 day, while no such thrombus was observed in coated stents group. Degree of hyperplasia of coronary endarterectomy in bare metal stents group was evidently higher than those in coated stents group. Obvious stent restenosis was discovered only in one case in bare metal stents group (diameter stenosis ≥50%). However, no case in coated stents group showed with stent restenosis. CONCLUSION Tissue factor pathway inhibitor-coated stents could successfully transfect TFPI gene into vessel wall cells, thereby inhibiting restenosis without obvious side effect in the rabbit carotid artery model.
