Development of a decellularized human amniotic membrane-based electrospun vascular graft capable of rapid remodeling for small-diameter vascular applications. Acta Biomater 2022; 152:144-156. [PMID: 36108966 DOI: 10.1016/j.actbio.2022.09.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 09/04/2022] [Accepted: 09/06/2022] [Indexed: 11/20/2022]
Abstract
The performance of small-diameter vascular grafts adapted to vascular replacement is commonly hindered by stenosis. To address this issue, a graft featuring rapid remodeling with degradation is warranted. In this work, a 1.8-mm-diameter graft was constructed by fabricating a decellularized human amniotic membrane (HAM) with polycaprolactone (PCL)/silk fibroin (SF) around it through electrospinning, namely, an HPS graft, and applied in a rat aortic grafting model for comparison to a decellularized porcine small intestinal submucosa (SIS)-integrated PCL/SF (SPS) graft and an autologous aorta. In vitro studies demonstrated that HAM provided a bioactive milieu for rapid endothelial cell proliferation and resisting fibroblast-induced collagen secretion. PCL/SF provides a biocompatible microenvironment for cellular infiltration with mechanical properties resembling those of the rat aorta. In vivo studies showed that the HPS graft induced functional endothelialization more rapidly, along with less intensive ECM deposition than the SPS graft upon the histologically weaker inflammatory response and foreign body reaction 4 weeks after implantation, and maintained patency by progressively stabilizing the remodeling structure approximating the native counterparts over 24 weeks. The bioengineered graft expands the applicability of allogeneic matrices with degradable electrospun polymers for long-term in situ vascular applications. STATEMENT OF SIGNIFICANCE: An orchestrated remodeling of the vascular graft, featuring rapid endothelialization and resisting extracellular matrix (ECM) deposition on the luminal surface, with a mechanically stable structure, is requisite for long-term vascular patency. Nevertheless, off-the-shelf grafts might not fulfil the criteria under abdominal aortic pressure. Herein, we fabricated a 1.8-mm-diameter vascular graft through the integration of a decellularized human amniotic membrane (HAM) with electrospun polycaprolactone (PCL)/silk fibroin (SF). In a rat aortic grafting model, the graft is capable of rapid endothelialization and resisting collagen deposition and provides a native-like mechanical structure for stabilizing the remodeling process towards that of the native aorta. This bioengineered graft has potential for small-diameter vascular regeneration, and provides advanced strategies to facilitate full-remodeling tissue applications.

Abstract
The anticoagulation treatment of cardiovascular patients, which is mandatory after implantation of heart valves or stents, has significantly adverse effects on life quality. This treatment can be reduced or even circumvented by developing novel antithrombogenic surfaces of blood-contacting implants. Thus, we aim to discover materials exhibiting outstanding hemocompatibility compared to other available synthetic materials. We present promising surficial characteristics of single crystalline alumina in terms of platelet activation inhibition. In order to elucidate the relation between its crystallographic properties including the plane orientation and blood cell behavior, we examined endothelialization, cytocompatibility, and platelet activation at the blood-alumina interfaces in a controlled experimental setup. We observed that the cell response is highly sensitive to the plane orientation and differs significantly for (0001) and (11-20) planes of Al2O3. Our results reveal for the first time the dependence of platelet activation on crystallographic orientation, which is assumed to be a critical condition controlling the thrombogenicity. Additionally, we used an endothelial cell monolayer as an internal control since endothelial cells have an impact on vessel integrity and implant acceptance. We successfully demonstrate that Al2O3(11-20) exhibits enhanced hemocompatibility in contrast to Al2O3(0001) and is comparable to the physiological endothelial monolayer in vitro.

Antithrombotic Treatment in Diabetes Mellitus: A Review of the Literature about Antiplatelet and Anticoagulation Strategies Used for Diabetic Patients in Primary and Secondary Prevention.

Abstract
Background:
Diabetes mellitus (DM) is on the rise globally. Its prevalence has nearly doubled
during the last two decades and it is estimated to affect 8.8% of the global population.
Cardiovascular disease (CVD) is the leading cause of death in diabetic population and despite
modern anti-inflammatory and cardioprotective therapeutic strategies diabetic patients have at
least a twice fold risk of cardiovascular events. Prothrombotic state in DM is associated with
multiple determinants such as platelet alterations, oxidative stress, endothelial changes,
circulating mediators. Thus, proper antithrombotic strategies to reduce the risk of CVD in this
population is critical.
Methods:
This article reviews the current antiplatelet and anticoagulant
agents in the aspect of primary and secondary prevention of CVD in the diabetic population.
Results:
The use of aspirin may be considered only at high-risk patients in the absence of
contraindications. Cangrelor was not inferior to clopidogrel in preventing the composite outcome
of CV death, myocardial infraction and revascularization without increasing major bleeding.
Triple therapy in the subpopulation with DM significantly reduced the composite primary
outcome of CV death, myocardial infraction or repeat target lesion revascularization. That was
not the case for stent thrombosis, which was similar in both groups. Importantly, triple therapy
did not result in increased bleeding complications, which were similar in both groups. However,
cilostazol is linked to various adverse effects (e.g., headache, palpitations, and gastrointestinal
disturbances) that drive many patients to withdrawal.
Conclusion:
In conclusion, DM is a
rapidly growing disease that increases the risk of CVD, AF, and CV mortality. Proper
antithrombotic strategies to reduce CVD risk in DM is a necessity. Also, new antithrombotic
treatments and combination therapies may play a critical role to overcome antiplatelet resistance
in DM patients and reduce morbidity and mortality attributed to CVD.

Abstract
Pigment epithelium-derived factor (PEDF) is one of the serine protease inhibitors with multifunctional properties, which is produced by various types of organs and tissues. There is an accumulating body of evidence that PEDF plays an important role in the maintenance of tissue homeostasis. Indeed, PEDF not only works as an endogenous inhibitor of angiogenesis, but also suppresses oxidative stress, inflammatory and thrombotic reactions in cell culture systems, animal models, and humans. Furthermore, we, along with others, have found that PEDF inhibits proliferation of, and induces apoptotic cell death in, numerous kinds of tumors. In addition, circulating as well as tumor expression levels of PEDF have been inversely associated with tumor growth and metastasis. These observations suggest that supplementation of PEDF proteins and/or enhancement of endogenous PEDF expression could be a novel therapeutic strategy for the treatment of cancer. Therefore, in this paper, we review the effects of PEDF on diverse types of cancer, and discuss its therapeutic perspectives.

Abstract
Pigment epithelium-derived factor (PEDF) is a secreted glycoprotein that has anti-angiogenic, anti-proliferative, neurotrophic and immunomodulatory properties. PEDF has recently emerged as a critical metabolic regulatory protein since the discovery of its modulatory activities in the lipolytic pathway by binding to adipose triglyceride lipase (ATGL). Despite being beneficial in maintaining the homeostasis of hepatic lipid accumulation, PEDF has been uncovered an unfavorable role associated with insulin resistance. The molecular events that connect these two apparent distinct observations have been controversial and remained largely unknown. Therefore in this short review, we attempt to summarize the current findings of PEDF regarding its lipid metabolic functions and provide perspectives in identifying PEDF as a potential therapeutic target in lipid disorders.

Abstract
Coronary artery disease remains the leading cause of mortality in adult diabetic population with however, a high predominance also in non-diabetic subjects. In search of common molecular mechanisms and metabolic by-products with potential pathogenic role, increased advanced glycation end products (AGEs) present a critical biomarker for CAD development in both cases. Interaction of AGEs with their transmembrane cell receptor, RAGE in endothelial and smooth muscle cells as well as in platelets, activates intracellular signaling that leads to endothelial injury, modulation of vascular smooth muscle cell function and altered platelet activity. Furthermore, tissue accumulation of AGEs affects current treatment approaches being involved in stent restenosis. The present review provides an update of AGE-induced molecular mechanisms involved in CAD pathophysiology while it discusses emerging therapeutic interventions targeting AGE reduction and AGE-RAGE signaling with beneficial clinical outcome.

Abstract
The significance of oxidative stress in the development of chronic neurodegenerative diseases of the retina has become increasingly apparent in recent years. Reactive oxygen species (ROS) are free radicals produced at low levels as a result of normal cellular metabolism that are ultimately metabolized and detoxified by endogenous and exogenous mechanisms. In the presence of oxidative cellular stress, ROS are produced in excess, resulting in cellular injury and death and ultimately leading to tissue and organ dysfunction. Recent studies have investigated the role of excess ROS in the pathogenesis and development of chronic neurodegenerative diseases of the retina including glaucoma, diabetic retinopathy, and age-related macular degeneration. Findings from these studies are promising insofar as they provide clear rationales for innovative treatment and prevention strategies of these prevalent and disabling diseases where currently therapeutic options are limited. Here, we briefly outline recent developments that have contributed to our understanding of the role of ROS in the pathogenesis of chronic neurodegenerative diseases of the retina. We then examine and analyze the peer-reviewed evidence in support of ROS as targets for therapy development in the area of chronic neurodegeneration of the retina.

Abstract
There is a growing body of evidence that cumulative hyperglycemic exposure plays a central role in the development and progression of atherosclerotic cardiovascular disease in diabetic patients. Monosaccharides, such as glucose, fructose, and glyceraldehyde can react non-enzymatically with amino groups of proteins, lipids, nucleic acids to form senescent macromolecules termed advanced glycation end products (AGEs), whose formation and accumulation has been known to progress in diabetic patients, especially in those with a long history of disease. The sustained accumulation of AGEs could contribute to the phenomenon of metabolic memory or legacy effects observed in long-term follow-up clinical studies of diabetic patients. AGE modification alters the structural integrity and function of various types of macromolecules, and interaction of AGEs with a receptor for AGEs (RAGE) has been shown to evoke inflammatory and thrombotic reactions. Therefore, the AGE–RAGE axis is a novel therapeutic target of atherosclerotic cardiovascular disease in diabetic patients. In this paper, we briefly review the pathological role of AGEs and their receptor RAGE system in atherosclerotic cardiovascular disease, including peripheral artery disease and discuss the clinical utility of measuring AGEs in evaluating the severity of atherosclerosis in patients with diabetes.

Abstract
BACKGROUND Pigment epithelium-derived factor (PEDF) is a glycoprotein that belongs to the superfamily of serine protease inhibitors. It is thought that PEDF plays a protective role against atherosclerosis. Clinical studies have shown that serum levels of PEDF are increased in subjects with cardiovascular risk factors. The role of PEDF in cardiovascular disease is still controversial. The purpose of this study was to evaluate the associations between serum levels of PEDF and vascular function and structure. METHODS We measured serum levels of PEDF, assessed vascular function by measurements of flow-mediated vasodilation (FMD) and nitroglycerine-induced vasodilation in the brachial artery, and measured brachial artery intima-media thickness (IMT) in 150 subjects who underwent health examinations. RESULTS AND CONCLUSIONS Univariate regression analysis revealed that serum level of PEDF was significantly correlated with body mass index, high-density lipoprotein cholesterol, glucose, FMD, nitroglycerine-induced vasodilation, and brachial artery IMT. Multivariate analysis revealed that serum levels of PEDF remained an independent predictor of nitroglycerine-induced vasodilation (β=-0.20, P=0.02) and brachial artery IMT (β=0.14, P=0.03) after adjustment of cardiovascular risk factors, while serum level of PEDF was not associated with FMD (β=-0.02, P=0.79). These findings suggest that PEDF may be a factor directly associated with atherosclerosis. The serum level of PEDF may be a new biochemical marker of atherosclerosis.

Abstract
Context Diabetes is a global health challenge. Although large prospective clinical trials have shown that intensive control of blood glucose or blood pressure reduces the risk for development and progression of vascular complications in diabetes, a substantial number of diabetic patients still experience renal failure and cardiovascular events, which could account for disabilities and high mortality rate in these subjects. Objective Sulphoraphane is a naturally occurring isothiocyanate found in widely consumed cruciferous vegetables, such as broccoli, cabbage and Brussels sprouts, and an inducer of phase II antioxidant and detoxification enzymes with anticancer properties. We reviewed here the protective role of sulphoraphane against diabetic vascular complications. Methods In this review, literature searches were undertaken in Medline and in CrossRef. Non-English language articles were excluded. Keywords [sulphoraphane and (diabetes, diabetic nephropathy, diabetic retinopathy, diabetic neuropathy, diabetic complications, vascular, cardiomyocytes, heart or glycation)] have been used to select the articles. Results There is accumulating evidence that sulphoraphane exerts beneficial effects on vascular damage in both cell culture and diabetic animal models via antioxidative properties. Furthermore, we have recently found that sulphoraphane inhibits in vitro formation of advanced glycation end products (AGEs), suppresses the AGE-induced inflammatory reactions in rat aorta by reducing receptor for AGEs (RAGE) expression and decreases serum levels of AGEs in humans. Conclusion These findings suggest that blockade of oxidative stress and/or the AGE-RAGE axis by sulphoraphane may be a novel therapeutic strategy for preventing vascular complications in diabetes.

Abstract
OBJECTIVES Obesity increases the incidence of multiple types of cancer. Our previous work has shown that a high-fat, high-calorie diet (HFCD) leads to visceral obesity, pancreatic inflammation, and accelerated pancreatic neoplasia in KrasG12D (KC) mice. In this study, we aimed to investigate the effects of an HFCD on visceral adipose inflammation with emphasis on potential differences between distinct visceral adipose depots. METHODS We examined the weight and visceral obesity in both wild-type and KC mice on either control diet (CD) or HFCD. After 3 months, mice were killed for histological examination. Multiplex assays were also performed to obtain cytokine profiles between different adipose depots. RESULTS Both wild-type and KC mice on an HFCD exhibited significantly increased inflammation in the visceral adipose tissue, particularly in the peripancreatic fat (PPF), compared with animals on a CD. This was associated with significantly increased inflammation in the pancreas. Cytokine profiles were different between visceral adipose depots and between mice on the HFCD and CD. CONCLUSIONS Our results clearly demonstrate that an HFCD leads to obesity and inflammation in the visceral adipose tissue, particularly the PPF. These data suggest that obesity-associated inflammation in PPF may accelerate pancreatic neoplasia in KC mice.

Abstract
The innermost layer of fetal membranes is amnion which has anti-adhesive, anti-inflammation and viscoelastic properties, as well as low immunogenicity. Amniotic membrane has been employed in variety of clinical fields as a natural biomaterial. Amniotic epithelial cells possess stem cell characteristics and capability to differentiate into endothelial cells. The basement membrane of amnion is an extracellular matrix enriched scaffold to support adhesion of endothelial cells. The matrix of amniotic membrane contains two kinds of glycosaminoglycans including perlecan (a heparan sulfate proteoglycan) and hyaluronic acid which both inhibit blood coagulation. Moreover, the other ingredients of amniotic membrane such as pigment-epithelium derived factor (PEDF), IL-10, MMP-9 inhibit platelet aggregation. Based on some biochemical and biomechanical evidences, we hypothesized in this paper that amniotic membrane could prevent thrombosis and hemolysis; therefore, has the capability to be applied in blood contacting devices and implants.

Serum levels of pigment epithelium-derived factor (PEDF) are inversely associated with circulating levels of dipeptidyl peptidase-4 (DPP-4) in humans. Int J Cardiol 2015; 184:14-16.

Abstract
BACKGROUND We have previously found that advanced glycation end products (AGEs) stimulate the proteolytic cleavage of dipeptidyl peptidase-4 (DPP-4) from plasma membranes, and circulating AGE levels are independently correlated with serum DPP-4 values. Since pigment epithelium-derived factor (PEDF), one of the adipocytokines, inhibits the AGEs-induced insulin resistance and vascular damage, it is conceivable that besides AGEs, PEDF might also regulate soluble DPP-4 levels. In this study, we addressed the issue. STUDY DESIGN AND METHODS The study involved 188 subjects (123 males and 65 females; mean age of 61.1±9.2) who visited our hospital for a risk-screening test or treatment for cardiovascular disease. They underwent complete history and physical examinations, and determination of blood chemistry and anthropometric variables, including visceral and subcutaneous fat areas. Serum levels of DPP-4 and PEDF levels were examined by enzyme-linked immunosorbent assay. RESULTS Median (interquartile range) serum levels of DPP-4 and PEDF were 466.6 (400.2-545.1) ng/mL and 14.0 (10.6-17.0) μg/mL, respectively. Multiple stepwise regression analysis revealed that female (p<0.001), aspartate aminotransferase (p<0.001), glycated hemoglobin (p<0.001) and PEDF (inversely, p=0.020) were independently associated with DPP-4 levels (R(2)=0.267). CONCLUSION We found here for the first time that serum PEDF levels were one of the independent correlates of circulating DPP-4 levels in humans. Since DPP-4 could impair insulin action and evoke vascular damage, our present study suggests that insulin-sensitizing and atheroprotective properties of PEDF might be ascribed partly to its inhibitory actions on DPP-4.

Abstract
Pigment epithelium-derived factor (PEDF) is a pluripotent glycoprotein belonging to the serpin family. PEDF can stimulate several physiological processes such as angiogenesis, cell proliferation, and survival. Oxidative stress plays an important role in the occurrence of diabetic retinopathy (DR), which is the major cause of blindness in young diabetic adults. PEDF plays a protective role in DR and there is accumulating evidence of the neuroprotective effect of PEDF. In this paper, we review the role of PEDF and the mechanisms involved in its antioxidative, anti-inflammatory, and neuroprotective properties.

Abstract
Oxidative stress and inflammation in the adipose tissues contribute to the metabolic syndrome. Pigment epithelium-derived factor (PEDF) inhibits vascular inflammation through its anti-oxidative properties. However, it remains unclear whether PEDF could suppress adipocyte inflammation. We investigated the effects of long-term administration or suppression of PEDF on adipocyte inflammation and metabolic derangements in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, an animal model of type 2 diabetes with insulin resistance. Circulating and adipose tissue PEDF levels were increased as OLETF rats became more obese and insulin resistant. Long-term administration of PEDF improves metabolic parameters, ameliorates dysregulation of adipocytokines, and suppresses NADPH oxidase-induced oxidative stress and macrophage infiltration in the adipose tissues of OLETF rats, whereas these variables are exacerbated by the knockdown of PEDF by administering siRNAs. Our study suggests that PEDF could improve metabolic derangements by suppressing the inflammatory and oxidative reactions in adipose tissues of OLETF rats. PEDF levels may be elevated as a countersystem against obesity-related metabolic derangements.

Abstract
Pigment epithelium-derived factor (PEDF) plays a protective role against atherosclerosis. Although serum PEDF level is increased in patients undergoing regular hemodialysis (HD), the pathophysiological role of PEDF in HD patients is unknown. We measured serum PEDF levels in 74 HD patients, and the association between serum PEDF and adverse events such as all-cause death and cardiovascular accident was evaluated prospectively. During the follow up of 45.4 ± 25.1 months, 24 patients (32.4%) experienced cardiovascular accident and 18 (24.3%) died. Significantly higher incidences of all-cause mortality and cardiovascular accident were observed in the lower PEDF group than in the higher PEDF group. After adjusting for propensity score calculated from multiple confounding factors (age, gender, systolic blood pressure, history of previous cardiovascular disease, level of carbonyl content, albumin, hemoglobin, total cholesterol, creatinine, C-reactive protein, dialysis vintage, Kt/V-urea and history of diabetes), lower predialytic PEDF was a significant risk factor for all-cause mortality (relative hazard = 6.060, standard error = 0.68467, P = 0.0085). Lower levels of predialytic PEDF was associated with an increased risk of mortality.

Abstract
Pigment epithelium-derived factor (PEDF) exerts atheroprotective effects both in cell culture and animal models through its anti-oxidative and anti-inflammatory properties. Caveolin-1 (Cav), a major protein component of caveolae in endothelial cells (ECs), plays a role in the progression of atherosclerosis. However, effects of PEDF on Cav-exposed ECs remain unknown. In this study, we examined whether and how PEDF could inhibit the Cav-induced inflammatory and thrombogenic reactions in human umbilical vein ECs (HUVECs). Surface plasmon resonance revealed that PEDF bound to Cav at the dissociation constant of 7.36×10(-7) M. Further, one of the major Cav-interacting proteins in human serum was identified as PEDF by peptide mass fingerprinting analysis using BIAcore 1000 combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Exogenously added Cav was taken up into the membrane fraction of HUVECs and dose-dependently increased monocyte chemoattractant protein-1 (MCP-1), vascular cell adhesion molecule-1 (VCAM-1) and plasminogen activator inhibitor-1 (PAI-1) mRNA levels, all of which were blocked by the simultaneous treatment with 10nM PEDF. Small interfering RNAs directed against Cav decreased endogenous Cav levels and suppressed gene expression of MCP-1, VCAM-1 and PAI-1 in HUVECs. This study indicates that PEDF binds to Cav and could block the inflammatory and thrombogenic reactions in Cav-exposed HUVECs. Our present study suggests that atheroprotective effects of PEDF might be partly ascribed to its Cav-interacting properties.

Abstract
OBJECTIVES Oxidative stress has a clear pro tumoral effect in myeloproliferative neoplasms (MPDs). In this study, we analyzed oxidative stress in patients with essential thrombocythemia (ET) and polycythemia vera (PV). Design and methods We analyzed serum levels of advanced oxidation protein products (AOPPs) degradation, advanced glycation end products (AGEs), and protein nitrosylation in ET and PV patients. We also evaluated neutrophil gelatinase-associated lipocalin (NGAL) levels, an acute phase protein isolated in human neutrophils, the activation status of platelets and leukocytes, and the JAK2 (V617F) mutation status. RESULTS AOPPs and s-nitrosylated proteins were significantly higher in PV and ET subjects as compared to healthy volunteers, while AGEs were higher in ET subjects with respect to controls. Moreover, in PV patients we found a correlation between s-nitrosylated proteins and Hb value. In ET patients AGEs were significantly higher in patients with thrombosis compared with those without thrombotic events. CONCLUSIONS Our results suggest that oxidative stress could play a role in the physiopathology of MPDs and in the onset of myeloproliferative associated thrombotic risk.

Abstract
Diabetes mellitus has been associated with platelet hyperreactivity, which plays a central role in the hyperglycemia-related prothrombotic phenotype. The mechanisms responsible for this phenomenon are not established. In the present study, we investigated the role of CD36, a class-B scavenger receptor, in this process. Using both in vitro and in vivo mouse models, we demonstrated direct and specific interactions of platelet CD36 with advanced glycation end products (AGEs) generated under hyperglycemic conditions. AGEs bound to platelet CD36 in a specific and dose-dependent manner, and binding was inhibited by the high-affinity CD36 ligand NO(2)LDL. Cd36-null platelets did not bind AGE. Using diet- and drug-induced mouse models of diabetes, we have shown that cd36-null mice had a delayed time to the formation of occlusive thrombi compared with wild-type (WT) in a FeCl(3)-induced carotid artery injury model. Cd36-null mice had a similar level of hyperglycemia and a similar level of plasma AGEs compared with WT mice under this condition, but WT mice had more AGEs incorporated into thrombi. Mechanistic studies revealed that CD36-dependent JNK2 activation is involved in this prothrombotic pathway. Therefore, the results of the present study couple vascular complications in diabetes mellitus with AGE-CD36-mediated platelet signaling and hyperreactivity.

Abstract
This article provides an overview of the current knowledge on intraplatelet oxidative/nitrative stress, an abnormality associated with platelet activation and hyper-reactivity. The first issue discussed is related to induction of platelet endogenous stress by the molecules present within the circulating (extracellular) milieu that bathes these cells. The second issue concerns the intraplatelet oxidative/nitrative stress associated with specific pathologies or clinical procedures and action of particular molecules and platelet agonists as well as of the specialized intraplatelet milieu and its redox system; the biomarkers of endogenous oxidative/nitrative stress are also briefly outlined. Next, the association between intraplatelet oxidative/nitrative stress and the risk factors of the metabolic syndrome is presented. Then, the most recent strategies aimed at the control/regulation of platelet endogenous oxidative/nitrative stress, such as exploitation of circulating extracellular reactive oxygen species scavengers, manipulation of platelet molecules, and the use of antioxidants, are discussed. Finally, the results of studies on platelet-dependent redox mechanisms, which deserve immediate attention for potential clinical exploitation, are illustrated.

Abstract
Diabetic retinopathy (DR) is a major cause of blindness in working age adults, and oxidative stress plays a vital role in the pathogenesis of DR. Pigment-epithelium-derived factor (PEDF), a multifunctional protein, has shown to inhibit the development of DR by accumulating evidence. This paper highlights the current understanding of probable mechanism about how PEDF blocks the deterioration of DR through its antioxidative properties and application prospects of PEDF as a novel therapeutic target in DR. Gene therapy of PEDF is becoming more and more acceptable and will widely be applied to the actual treatment in the near future.

Abstract
The authors previously demonstrated decreased levels of pigment epithelium-derived factor (PEDF) in peritoneal fluid of women with endometriosis compared to women without endometriosis. Here, the authors determine whether women with endometriosis have altered levels of PEDF in serum. Peripheral blood samples were collected from 71 women with and without endometriosis (n = 43 and 28, respectively) before laparoscopic surgery. Concentrations of serum PEDF were measured by enzyme-linked immunosorbent assay. We detected lower levels of serum PEDF in women with endometriosis (16.3 ± 6.6 ng/mL) than in those without endometriosis (24.5 ± 7.3 ng/mL; P < .001). In women with endometriosis, the concentrations of serum PEDF were significantly lower in women with pain (n = 11, 12.6 ± 7.1 ng/mL) compared to women without pain (n = 32, 17.5 ± 6.0 ng/mL; P < .05). However, the concentrations of serum PEDF did not correlate with disease stage or site or infertility. In addition, the concentrations of serum PEDF did not show any difference in the phase of the cycle in either group. Our results suggest that reduced levels of serum PEDF in women with endometriosis and disease-related pain may play a role in the pathogenesis of this disease.

Abstract
Oxidative stress and inflammation are involved in cardiac remodeling after acute myocardial infarction (AMI). We have found that pigment epithelium-derived factor (PEDF) inhibits vascular inflammation through its anti-oxidative properties. However, effects of PEDF on cardiac remodeling after AMI remain unknown. We investigated whether PEDF could inhibit left ventricular remodeling and improve cardiac function in rats with AMI. AMI was induced in 8-week-old Sprague-Dawley rats by ligation of the left ascending coronary artery. Rats were treated intravenously with vehicle or 10 μg PEDF/100 g b.wt. every day for up to 2 weeks after AMI. Each rat was followed until 16 weeks of age. PEDF levels in infarcted areas and serum were significantly decreased at 1 week after AMI and remained low during the observational periods. PEDF administration inhibited apoptotic cell death and oxidative stress generation around the infarcted areas at 2 and 8 weeks after AMI. Further, PEDF injection suppressed cardiac fibrosis by reducing transforming growth factor-β and type III collagen expression, improved left ventricular ejection fraction, ameliorated diastolic dysfunction, and inhibited the increase in left ventricular mass index at 8 weeks after AMI. The present study demonstrated that PEDF could inhibit tissue remodeling and improve cardiac function in AMI rats. Substitution of PEDF may be a novel therapeutic strategy for cardiac remodeling after AMI.

Abstract
OBJECTIVE Recent evidence has strongly suggested that atherosclerosis is an angiogenic disease, and PEDF may play a significant role in determining the balance of angiogenesis/antiangiogenesis during atherogenesis. Therefore, we assessed the associations among plasma levels of pigment epithelium-derived factor (PEDF), high-sensitivity C-reactive protein (hsCRP), the lipid profile and tissue characteristics of coronary plaque as assessed by integrated backscatter intravascular ultrasound (IB-IVUS). METHODS Fifty-two consecutive patients with stable coronary artery disease who underwent percutaneous coronary intervention were enrolled. Non-target coronary lesions with mild to moderate stenosis were measured by IB-IVUS. A total of 20 IB-IVUS images were recorded at an interval of 0.5 mm for a length of 10 mm in each plaque. RESULTS Although the percentage of plaque volume (%PV, 100×total PV/total vessel volume), percentage of lipid volume (%LV, 100×LV/PV) and percentage of fibrous volume (%FV, 100×FV/PV) were not associated with plasma log[PEDF] levels in the overall patients, in the patients without statin treatment %LV and %FV were correlated with plasma log[PEDF] levels (r=0.525, p=0.021 and r=-0.498, p=0.030, respectively). CONCLUSION The plasma level of PEDF may be a useful biomarker for predicting the tissue characteristics of coronary plaque using IB-IVUS.

Abstract
Pigment epithelium-derived factor (PEDF) is an endogenously produced glycoprotein with a spectrum of biological roles across diverse pathologies. Recent research has focused on the biochemical properties of PEDF and its associated receptors. This review discusses the recent developments in PEDF biochemistry and how this new knowledge will help progress our understanding of PEDF as a molecular mediator for anti-angiogenesis and -tumorigenesis. Additionally, pathophysiological roles for PEDF in healing and tissue homeostasis are being revealed and our enhanced understanding of the interactions between PEDF and its receptors may yet prove useful in propelling PEDF towards clinical application.

Abstract
In this review we discuss the role of pigment epithelium-derived factor (PEDF) as a possible new target molecule to therapeutically influence cardiovascular disease. PEDF is a multifunctional, pleiotropic protein with antiangiogenic, antitumorigenic, antioxidant, anti-inflammatory, antithrombotic, neurotrophic and neuroprotective properties. First identified in retinal pigment epithelium cells, it is expressed in various tissues throughout the body such as the eye, liver and adipose tissue. Recently PEDF has also been characterized in the heart. PEDF has been suggested to have a protective role in atherosclerosis, the main cause of coronary heart disease, myocardial infarction and heart failure due to its anti-inflammatory, antioxidant and antithrombotic effects in the vessel wall and platelets. Additionally PEDF has strong antiangiogenic effects by inducing apoptosis in endothelial cells and by regulating the expression of other angiogenic factors. Therefore blocking of PEDF locally for example in ischemic tissue in the heart might favour angiogenesis, induce neovascularization and lead to increased perfusion of the injured tissue. On the other hand, local overexpression of PEDF restricted to atherosclerotic lesions might block angiogenesis, inflammation and thrombosis at these sites and thus counteract destabilization and rupture of the lesion otherwise caused by inflammatory activation and excessive angiogenesis and inhibit subsequent thrombus formation.

Positive association of circulating levels of advanced glycation end products (AGEs) with pigment epithelium-derived factor (PEDF) in a general population. Pharmacol Res 2009; 61:103-7.

Abstract
We have recently found that serum levels of pigment epithelium-derived factor (PEDF), a glycoprotein with anti-oxidative and anti-inflammatory properties, are elevated in proportion to the accumulation of the number of the components of the metabolic syndrome. Since formation and accumulation of advanced glycation end products (AGEs) progress under the metabolic syndrome and that PEDF could inhibit the AGE-elicited tissue damage, it is conceivable that PEDF levels may be increased as a counter-system against AGEs in patients with the metabolic syndrome. However, correlation between circulating levels of AGEs and PEDF in humans remains to be elucidated. In this study, we investigated the relationship between serum AGE and PEDF levels in a general population and examined the effects of AGEs on PEDF gene expression in vitro. One hundred ninety-six Japanese subjects in a general population underwent a complete history and physical examination, determination of blood chemistries, including serum levels of AGEs and PEDF. In multiple regression analyses, creatinine, body mass index, triglycerides, AGEs and insulin were independently correlated with serum PEDF levels. AGEs dose-dependently increased PEDF gene expression in cultured adipocytes and liver cells. Our present study demonstrated first that circulating AGEs were one of the independent correlates of serum levels of PEDF. Adipose tissue and liver may be target organs for the AGE-induced PEDF overexpression in humans. Serum PEDF levels may be elevated in response to circulating AGEs as a counter-system against the AGE-elicited tissue damage.
