Abstract
Cell surface proteins are responsible for many crucial physiological roles, and they are also the major category of drug targets as the majority of therapeutics target membrane proteins on the surface of cells to alter cellular signaling. Despite its great significance, ligand discovery against membrane proteins has posed a great challenge mainly due to the special property of their natural habitat. Here, we design a new chemical proteomic probe OPA-S-S-alkyne that can efficiently and selectively target the lysines exposed on the cell surface and develop a chemical proteomics strategy for global analysis of surface functionality (GASF) in living cells. In total, we quantified 2639 cell surface lysines in Hela cell and several hundred residues with high reactivity were discovered, which represents the largest dataset of surface functional lysine sites to date. We discovered and validated that hyper-reactive lysine residues K382 on tyrosine kinase-like orphan receptor 2 (ROR2) and K285 on Endoglin (ENG/CD105) are at the protein interaction interface in co-crystal structures of protein complexes, emphasizing the broad potential functional consequences of cell surface lysines and GASF strategy is highly desirable for discovering new active and ligandable sites that can be functionally interrogated for drug discovery.

Abstract
OBJECTIVES This study aimed to evaluate the effect of pravastatin to prevent preeclampsia (PE) in pregnant women at a high risk of developing PE and the maternal and perinatal outcomes and the soluble fms-like tyrosine kinase 1/placental growth factor (sFlt1/PlGF) ratio. STUDY DESIGN This is an open-labeled randomized controlled trial (RCT), a part of INOVASIA (Indonesia Pravastatin to Prevent Preeclampsia study) trial. Pregnant women at a high risk of developing PE were recruited and randomized into an intervention group (40) and a control group (40). The inclusion criteria consisted of pregnant women with positive clinical risk factor and abnormal uterine artery Doppler examination at 10 to 20 weeks' gestational age. The control group received low dose aspirin (80 mg/day) and calcium (1 g/day), while the intervention group received additional pravastatin (20-mg twice daily) starting from 14 to 20 weeks' gestation until delivery. Research blood samples were collected before the first dose of pravastatin and before delivery. The main outcome was the rate of maternal PE, maternal-perinatal outcomes, and sFlt-1, PlGF, sFlt-1/PlGF ratio, and soluble endoglin (sEng) levels. RESULTS The rate of PE was (nonsignificantly) lower in the pravastatin group compared with the control group (17.5 vs. 35%). The pravastatin group also had a (nonsignificant) lower rate of severe PE, HELLP (hemolysis, elevated liver enzymes and low platelets) syndrome, acute kidney injury, and severe hypertension. The rate of (iatrogenic) preterm delivery was significantly (p = 0.048) lower in the pravastatin group (n = 4) compared with the controls (n = 12). Neonates in the pravastatin group had significantly higher birth weights (2,931 ± 537 vs. 2,625 ± 872 g; p = 0.006), lower Apgar's scores < 7 (2.5 vs. 27.5%, p = 0.002), composite neonatal morbidity (0 vs. 20%, p = 0.005), and NICU admission rates (0 vs. 15%, p = 0.026). All biomarkers show a significant deterioration in the control group compared with nonsignificant changes in the pravastatin group. CONCLUSION Pravastatin holds promise in the secondary prevention of PE and placenta-mediated adverse perinatal outcomes by improving the angiogenic imbalance. KEY POINTS · Prophylactic pravastatin was associated with a significantly lower rate of adverse perinatal outcome.. · The sFlt1/PlGF ratio stabilized in the pravastatin group compared with a deterioration in the control group.. · Pravastatin holds promise in the secondary prevention of PE and placenta-mediated adverse perinatal outcomes..

Abstract
OBJECTIVES To ascertain whether abnormalities in neonatal head circumference and/or body weight are associated with levels of angiogenic/antiangiogenic factors in the maternal and cord blood of pregnancies with a congenital heart defect (CHD) and to assess whether the specific type of CHD influences this association. METHODS This was a multicenter case-control study of women carrying a fetus with major CHD. Recruitment was carried out between June 2010 and July 2018 at four tertiary care hospitals in Spain. Maternal venous blood was drawn at study inclusion and at delivery. Cord blood samples were obtained at birth when possible. Placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng) were measured in maternal and cord blood. Biomarker concentrations in the maternal blood were expressed as multiples of the median (MoM). RESULTS PlGF, sFlt-1 and sEng levels were measured in the maternal blood in 237 cases with CHD and 260 healthy controls, and in the cord blood in 150 cases and 56 controls. Compared with controls, median PlGF MoM in maternal blood was significantly lower in the CHD group (0.959 vs 1.022; P < 0.0001), while median sFlt-1/PlGF ratio MoM was significantly higher (1.032 vs 0.974; P = 0.0085) and no difference was observed in sEng MoM (0.981 vs 1.011; P = 0.4673). Levels of sFlt-1 and sEng were significantly higher in cord blood obtained from fetuses with CHD compared to controls (mean ± standard error of the mean, 447 ± 51 vs 264 ± 20 pg/mL; P = 0.0470 and 8.30 ± 0.92 vs 5.69 ± 0.34 ng/mL; P = 0.0430, respectively). Concentrations of sFlt-1 and the sFlt-1/PlGF ratio in the maternal blood at study inclusion were associated negatively with birth weight and head circumference in the CHD group. The type of CHD anomaly (valvular, conotruncal or left ventricular outflow tract obstruction) did not appear to alter these findings. CONCLUSIONS Pregnancies with fetal CHD have an antiangiogenic profile in maternal and cord blood. This imbalance is adversely associated with neonatal head circumference and birth weight. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
In vitro studies have shown that Wharton's jelly mesenchymal stem cells (WJ-MSCs) can cross umbilical and uterine endothelial barriers and up-regulate endothelial junctional integrity from sub-endothelial niches. This pericytic behaviour may be lost in pregnancies complicated by gestational diabetes (GDM), where increased vascular permeability and junctional disruption are reported. The aim of the present study was to investigate whether WJ-MSCs isolated from GDM pregnancies displayed any changes in morphology, proliferation, VEGF-A secretion, and their ability to influence paracellular junctional composition and permeability. WJ-MSCs were isolated from human umbilical cords from normal pregnancies (nWJ-MSCs, n=13) and those complicated by GDM (gWJ-MSCs), either diet-controlled (d-GDM, n=13) or metformin-treated (m-GDM, n=9). We recorded that 4-fold more WJ-MSCs migrated from m-GDM, and 2.5-fold from d-GDM cord samples compared with the normal pregnancy. gWJ-MSCs showed a less predominance of spindle-shaped morphology and secreted 3.8-fold more VEGF-A compared with nWJ-MSCs. The number of cells expressing CD105 (Endoglin) was higher in gWJ-MSCs compared with nWJ-MSCs (17%) at P-2. The tracer leakage after 24 h across the HUVEC + gWJ-MSCs bilayer was 22.13% and 11.2% higher in the m-GDM and d-GDM, respectively, HUVEC + nWJ-MSCs. Transfection studies with siRNAs that target Endoglin were performed in n-WJ-MSCs; transfected cells were co-cultured with HUVEC followed by permeability studies and VE-cadherin analyses. Loss of Endoglin also led to increased VEGF-A secretion, increased permeability and affected endothelial stabilization. These results reinforce the pericytic role of nWJ-MSCs to promote vascular repair and the deficient ability of gWJ-MSCs to maintain endothelial barrier integrity.

Abstract
INTRODUCTION In this study we analyzed CD105 (endoglin) and E-cadherin expression in laryngeal squamous cell carcinoma (LSCC) to evaluate their clinicopathologic significance. MATERIAL AND METHODS Expression of CD105 and E-cadherin was examined immunohistochemically using paraffin-embedded archival tissues of 72 (35 glottic and 37 supraglottic) previously untreated LSCC male patients. The mean value of the positively-stained microvessels for CD105 counted in four hot spots for each case was used as the final intratumoralmicrovessel density (MVD). A staining score of E-cadherin was calculated based on the percentage of cells stained (0-100%). RESULTS MVD was significantly higher in patients with advanced TNM stage (P = 0.004) and younger than 65 (P = 0.008). Nodal metastases were more frequent in the cases with low E-cadherin expression (P = 0.000). Tumor recurrence was associated with advanced TNM stage (P = 0.035) and high MVD (P = 0.002). A high MVD was an independent predictor of malignancy recurrence (P = 0.021). The log-rank test showed a significant difference in the disease-free interval in patients stratified according to the MVD value (P = 0.016). Spearman's rank correlation test did not show a significant correlation between E-cadherin and CD105 expression. CONCLUSIONS CD105-assessed MVD and expression of E-cadherin are promising prognostic factors for the outcome of patients with LSCC. Increased expression of CD105 could help predict patients with an increased risk of developing loco-regional recurrence after surgical treatment. Decreased E-cadherin expression is a potential predictor of lymph node metastases.

Abstract
PURPOSE To determine whether 14 inflammation-, angiogenesis-, and adhesion-related proteins in cord blood (CB), alone or in combination with conventional perinatal factors, could predict retinopathy of prematurity (ROP) in preterm infants. METHODS Data from 111 preterm infants (born at ≤ 32.0 weeks) were retrospectively reviewed. The levels of endoglin, E-selectin, HSP70, IGFBP-3/4, LBP, lipocaline-2, M-CSFR, MIP-1α, pentraxin 3, P-selectin, TGFBI, TGF-β1, and TNFR2 were assessed in stored CB samples collected at birth using ELISA kits. The primary endpoints included severe ROP (≥ stage 3) and type 1 ROP requiring treatment. RESULTS ROP was diagnosed in 29 infants (26.1%), among whom 14 (12.6%) had severe ROP and seven (6.3%) had type 1 ROP. Multivariate logistic regression showed that decreased CB TGFBI levels were significantly associated with severe ROP and type 1 ROP after adjusting for gestational age at birth. Stepwise regression analysis allowed to design prediction models with good accuracy, which comprised low CB TGFBI levels and low birth weight (BW) as predictors for severe ROP (area under the curve [AUC] = 0.888), and low CB endoglin levels and low BW as predictors for type 1 ROP (AUC = 0.950). None of the other CB proteins evaluated were found to be associated with severe ROP or type 1 ROP. CONCLUSIONS Low CB TGFBI levels are associated with severe ROP and type 1 ROP, independently of gestational age. Moreover, combined predictive models based on CB TGFBI and endoglin levels, along with BW data, may act as good indicators at birth for the neonatal risk of ROP progression.

Abstract
ABSTRACT Background: Endothelial activation is a key driver of multiple organ dysfunction syndrome (MODS). Soluble endoglin (sENG) is expressed by mature and progenitor endothelial cells and thought to have angiogenic properties. We sought to determine the association between sENG and pediatric sepsis-associated MODS. Methods: Prospective observational study of pediatric septic shock. Primary outcome of interest was complicated course-a composite of death by (or) MODS on day 7 of illness. Secondary outcomes included individual organ dysfunctions. Endothelial biomarkers including sENG were measured using multiplex Luminex assays among patients with existing data on the Pediatric Sepsis Biomarker Risk Model (PERSEVERE-II) data. Multivariable regression was used to test the independent association between sENG and clinical outcomes. Serum sENG concentrations across PERSEVERE-II mortality risk strata and correlations with established markers of endothelial dysfunction were determined. Results: Three hundred six critically ill children with septic shock were included. Serum sENG concentrations were higher among those with primary and secondary outcomes of interest, with the exception of acute neurological dysfunction. Soluble endoglin was independently associated with increased odds of complicated course (adjusted odds ratio, 1.53; 95% confidence interval, 1.02-2.27; P = 0.038) and acute renal dysfunction (adjusted odds ratio, 1.84; 95% confidence interval, 1.18-2.876; P = 0.006). Soluble endoglin demonstrated graded responses across PERSEVERE-II risk strata and was positively correlated with endothelial biomarkers, except angiopoietin-1. Conclusions: Serum sENG is independently associated with complicated course and acute renal dysfunction in pediatric septic shock. Future studies are required to validate our observational data, and mechanistic studies are necessary to elucidate whether endoglin plays an organ-specific role in the development or resolution of acute renal dysfunction in sepsis.

Abstract
Molecular biomarkers that interact with the vascular and immune compartments play an important role in the progression of solid malignancies. CD105, which is a component of the transforming growth factor beta (TGF β) signaling cascade, has long been studied for its role in potentiating angiogenesis in numerous cancers. In renal cell carcinoma (RCC), the role of CD105 is more complicated due to its diverse expression profile on the tumor cells, tumor vasculature, and the components of the immune system. Since its discovery, its angiogenic role has overshadowed other potential functions, especially in cancers. In this review, we aim to summarize the recent evidence and findings of the multifunctional roles of CD105 in angiogenesis and immunomodulation in the context of the various subtypes of RCC, with a specific emphasis on the clear cell RCC subtype. Since CD105 is an established biomarker and tumor antigen, we also provide an update on the preclinical and clinical applications of CD105 as a therapeutic platform in RCC.

Abstract
BACKGROUND Preeclampsia is a common but life-threatening condition of pregnancy. It is caused by poor placentation resulting in release of trophoblast material (including soluble endoglin (sEng)) into the maternal circulation leading to maternal vascular dysfunction and to the life-threatening condition of eclampsia. The only cure is early delivery, which can have lifelong consequences for the premature child. The thyroid hormone binding protein transthyretin is dysregulated in preeclampsia, however it is not known if this plays a role in disease pathology. We hypothesised that transthyretin may bind sEng and abrogate its negative effects by removing it from the maternal serum. METHODS The effect of transthyretin on hepatocyte uptake of Alexa-labelled sEng was measured using live cell imaging. Interactions between transthyretin, and sEng were investigated using molecular modelling, direct binding on CnBr Sepharose columns, confocal imaging, and measurement of fluorescence resonance energy transfer. RESULTS Transthyretin directly bound to sEng and increased its uptake by hepatocytes. This uptake was altered in the presence of transforming growth factor-β1 (TGF-β1). Molecular modelling predicted that transthyretin and TGF-β1 bind at the same site in sEng and may compete for binding. Endocytosed transthyretin and endoglin entered cells together and co-localised inside hepatocyte cells. CONCLUSION Transthyretin can bind sEng and increase its uptake from the extracellular medium. This suggests that increasing transthyretin levels or developing drugs that normalise or mimic transthyretin, may provide treatment options to reduce sEng induced vascular dysfunction.

Abstract
BACKGROUND AND AIMS Detailed investigation of the biological pathways leading to hepatic fibrosis and identification of liver fibrosis biomarkers may facilitate early interventions for pediatric cholestasis. APPROACH AND RESULTS A targeted enzyme-linked immunosorbent assay-based panel of nine biomarkers (lysyl oxidase, tissue inhibitor matrix metalloproteinase (MMP) 1, connective tissue growth factor [CTGF], IL-8, endoglin, periostin, Mac-2-binding protein, MMP-3, and MMP-7) was examined in children with biliary atresia (BA; n = 187), alpha-1 antitrypsin deficiency (A1AT; n = 78), and Alagille syndrome (ALGS; n = 65) and correlated with liver stiffness (LSM) and biochemical measures of liver disease. Median age and LSM were 9 years and 9.5 kPa. After adjusting for covariates, there were positive correlations among LSM and endoglin ( p = 0.04) and IL-8 ( p < 0.001) and MMP-7 ( p < 0.001) in participants with BA. The best prediction model for LSM in BA using clinical and lab measurements had an R2 = 0.437; adding IL-8 and MMP-7 improved R2 to 0.523 and 0.526 (both p < 0.0001). In participants with A1AT, CTGF and LSM were negatively correlated ( p = 0.004); adding CTGF to an LSM prediction model improved R2 from 0.524 to 0.577 ( p = 0.0033). Biomarkers did not correlate with LSM in ALGS. A significant number of biomarker/lab correlations were found in participants with BA but not those with A1AT or ALGS. CONCLUSIONS Endoglin, IL-8, and MMP-7 significantly correlate with increased LSM in children with BA, whereas CTGF inversely correlates with LSM in participants with A1AT; these biomarkers appear to enhance prediction of LSM beyond clinical tests. Future disease-specific investigations of change in these biomarkers over time and as predictors of clinical outcomes will be important.

Abstract
Now that mechanical thrombectomy has substantially improved outcomes after large-vessel occlusion stroke in up to every second patient, futile reperfusion wherein successful recanalization is not followed by a favorable outcome is moving into focus. Unfortunately, blood-based biomarkers, which identify critical stages of hemodynamically compromised yet reperfused tissue, are lacking. We recently reported that hypoxia induces the expression of endoglin, a TGF-β co-receptor, in human brain endothelium in vitro. Subsequent reoxygenation resulted in shedding. Our cell model suggests that soluble endoglin compromises the brain endothelial barrier function. To evaluate soluble endoglin as a potential biomarker of reperfusion (-injury) we analyzed its concentration in 148 blood samples of patients with acute stroke due to large-vessel occlusion. In line with our in vitro data, systemic soluble endoglin concentrations were significantly higher in patients with successful recanalization, whereas hypoxia alone did not induce local endoglin shedding, as analyzed by intra-arterial samples from hypoxic vasculature. In patients with reperfusion, higher concentrations of soluble endoglin additionally indicated larger infarct volumes at admission. In summary, we give translational evidence that the sequence of hypoxia and subsequent reoxygenation triggers the release of vasoactive soluble endoglin in large-vessel occlusion stroke and can serve as a biomarker for severe ischemia with ensuing recanalization/reperfusion.

Abstract
The aim of the study was to assess the role of concentrations of interleukin-17 (IL-17), placental growth factor (PlGF) and soluble endoglin (sENG), as well as the PlGF/sENG ratio in pregnancy complicated by pre-eclampsia (PE) and normal pregnancy. The concentrations of IL-17, PlGF and sENG were measured with the use of immunoenzymatic methods. The concentrations of IL-17 were significantly higher in PE patients when compared to control patients. In the group of patients with PE, the levels of IL-17 positively correlated with systolic blood pressure. On the other hand, IL-17 negatively correlated with neonatal birth weight. The concentrations of PLGF were significantly lower and sENG significantly higher in studied patients when compared to controls. The PlGF/sENG ratio in the PE group was significantly lower when compared to healthy third trimester pregnant patients. In the study group, negative correlations were observed between the sENG concentrations and thrombocyte levels. The higher concentrations of IL-17 in PE could suggest its role as an inflammatory agent in the pathogenesis of the syndrome. Moreover, the negative correlation between IL-17 and a neonatal birth weight could suggest the role of the cytokine in the development of fetal growth restriction (FGR) associated with PE. It seems possible that IL-17 can be a useful marker of the risk of FGR in pregnancy complicated by PE. Furthermore, the results suggested the potential role of sENG and the PlGF/sENG ratio in the prediction of adverse outcomes such as HELLP syndrome and DIC.

Abstract
The study aimed to evaluate the therapeutic effect of boric acid (BA) in experimentally induced septic arthritis. A total of 30 rats, 6 rats in each group (5 groups), were used in the study. No treatment was applied to the rats in the control group. Only BA was administered intraperitoneally (IP) to the rats in the bor group. Escherichia coli was administered at a single dose of 25 μL, 1 × 1010 cfu/rat from the right foot pad of the rats, via intra-articular route, to the mice in the arthritis, arthritis-bor, and arthritis-antb groups. Then, BA at a dose of 50 mg/kg and cefazolin at a dose of 25 mg/kg were administered to the rats in the arthritis-bor and arthritis-antb groups, respectively, for 7 days via the IP route. At the end of the study, all animals were euthanized following the ethical rules. Blood and tissue samples were taken from the rats for biochemical and histopathological analyses. The levels of GSH, MDA, Endoglin, Endocan, and TNF-β markers were measured in the blood samples taken. A significant decrease was observed in MDA and Endoglin levels in the boric acid-administered group compared with the arthritis group, while a significant increase was observed at the GSH level. Histopathologically, it was determined that the reactive surrounding tissue response in the bor group was significantly reduced. As a result, a significant decrease in inflammation was found biochemically and histopathologically in the groups treated with BA.

Abstract
Cancer is one of the diseases with the highest morbidity and mortality rates worldwide, and its therapeutic options are inadequate. The endothelial glycoprotein, also known as CD105, is a type I transmembrane glycoprotein located on the surface of the cell membranes and it is one of the transforming growth factor-β (TGF-β) receptor complexes. It regulates the responses associated with binding to transforming growth factor β1 egg (Activin-A), bone morphogenetic protein 2 (BMP-2), and bone morphogenetic protein 7 (BMP-7). Additionally, it is involved in the regulation of angiogenesis. This glycoprotein is indispensable in the treatment of tumor angiogenesis, and it also plays a leading role in tumor angiogenesis therapy. Therefore, CD105 is considered to be a novel therapeutic target. In this study, we explored the significance of CD105 in the diagnosis, treatment and prognosis of various tumors, and provided evidence for the effect and mechanism of CD105 on tumors.

Abstract
OBJECTIVES Maternal systemic and placental inflammatory responses participate in the pathogenesis of hypertensive disorders of pregnancy including preeclampsia, a pregnancy-specific syndrome, although the role of inflammation remains unclear. The NLRP3 inflammasome has been implicated in the control of sterile inflammation involved in preeclampsia. In the present study, we hypothesized that S100A9, as major alarmin, are associated with the pathogenesis of preeclampsia and induction of a preeclampsia-like phenotype in pregnant mice. METHODS Plasma were taken from normal pregnant women and preeclampsia patients. Human placental tissues, trophoblast cell line Sw.71 cells, and human umbilical vein endothelial cells (HUVEC) were treated with S100A9 with or without inhibitors associated with NLRP3 inflammasome. Pregnant mice were administered S100A9. RESULTS S100A9 was elevated in plasma and released from placentas of preeclampsia patients. S100A9 activated the NLRP3 inflammasome, resulting in IL-1β secretion, by human placental tissues and trophoblasts. In addition, secretion of soluble endoglin, a main contributor to the pathogenesis of preeclampsia, is regulated via S100A9-stimulated NLRP3 inflammasome activation in the human placenta and HUVECs. S100A9 administration significantly elevated maternal blood pressure and neutrophil accumulation within the placentas of pregnant mice, and both were significantly decreased in Nlrp3-knock out pregnant mice. CONCLUSION The results of this study demonstrated that S100A9 acts as a danger signal to activate the NLRP3 inflammasome in the placenta, associating with hypertension during pregnancy.

Abstract
AIM In this study, we aimed to investigate the soluble endoglin (sEng) levels in pregnant women with fetal growth restriction (FGR) and to examine the possible relation of the sEng levels with the time remaining to delivery and maternal and fetal complications. METHODS A total of 42 pregnant women diagnosed with FGR were retrospectively reviewed. Using the maternal blood samples it is at the collected 24-37 gestational weeks, the sEng levels were measured. Fetal biometry measurements, umbilical artery, uterine artery, middle cerebral artery Doppler indices were documented. RESULTS Of all patients, 17 (40%) were diagnosed with early-onset FGR, while 25 (60%) were diagnosed with late-onset FGR. Abnormal Doppler findings were present in 25 (60%) patients. Of 42 newborns, 18 (42%) were hospitalised in the neonatal unit. The mean sEng level calculated by taking the average of the first and second blood samples was 63.24 ± 49.83 ng/mL. There was no statistically significant difference in the mean sEng levels between those who gave birth within four, three, and two weeks after the diagnosis of FGR and those who did not. There was a positive significant correlation between the mean sEng levels and systolic blood pressure (r = 0.319, P = .04). CONCLUSIONS We did not find a statistically significant relationship between the sEng level and the time remaining to the time of delivery in pregnant women with FGR. We found no statistically significant difference in sEng level between the groups in pregnant women with fetuses with FGR with or without maternal and fetal complications.

Abstract
Objective To investigate whether angiogenic biomarker concentrations differ between women who deliver small‐for‐gestational‐age (SGA) infants (<10th centile birth weight for gestational age) compared with controls, because identifying SGA risk early could improve outcomes. Methods This case‐control study compared serum concentrations of angiogenic biomarkers before 24 weeks of pregnancy from 62 women who delivered SGA infants (cases) and 62 control women from an urban Zambian cohort. Odds of delivering an SGA infant were calculated using conditional logistic regression. Results Placental growth factor (PlGF), soluble fms‐like tyrosine kinase (sFLT‐1) and soluble endoglin (sEng) in controls were 37.74 pg/mL (interquartile range [IQR] 23.12–63.15), 2525.18 pg/mL (IQR 1502.21–4265.54) and 2408.18 pg/mL (IQR 1854.87–3017.94), respectively. SGA cases had higher PlGF (40.50 pg/mL, IQR 22.81–67.94) and sFLT‐1 (2613.06 pg/mL, IQR 1720.58–3722.50), and lower sEng (2038.06 pg/mL, IQR 1445.25–3372.26). Participants with sEng concentration below and concomitant sFLT‐1 concentration above their respective thresholds (n = 40) had five‐fold higher odds of SGA (adjusted odds ratio 4.77, 95% confidence interval 1.61–14.1; P = 0.005). Conclusion Biomarker concentrations were similar between cases and controls. Participants with concomitant low sEng and high sFLT‐1 had the highest odds of SGA, suggesting that a combination of biomarkers may better for predicting SGA than single biomarkers. Prediction of SGA risk using the interaction of multiple angiogenic biomarkers may perform better than using a single angiogenic biomarker concentration before 24 weeks gestation.

Abstract
In this research, we studied the therapeutic efficacy of a newly designed fusion protein containing Endoglin single-chain variable fragment and IP10 (Endoglin-scFv/IP10), together with our recently generated TRP2-specific CD8+ CD28+ CTLs (CD8+ CD28+ CTLs) in controlling melanoma growth in mice. The recombinant Endoglin-scFv/IP10 was expressed in E. coli, purified by affinity chromatography, and characterized in vitro for its chemotactic movement and immunoreactivity with endoglin-expressing cells. In vivo, melanoma xenografts were established in mice (C57BL/6) using B16F10 cells. After that, mice were treated with intravenous injections of vehicle (PBS), Endoglin-scFv/IP10 alone, CD8+ CD28+ CTLs alone, or Endoglin-scFv/IP10+ CD8+ CD28+ CTLs. The therapeutic efficacy was assessed by monitoring tumor growth, mouse survival and cellular biomarkers. Endoglin-scFv/IP10 fusion protein combined with CD8+ CD28+ CTLs observed a reduction in tumor growth, resulting in improved survival. On the cellular level, the combination treatment dramatically reduced the number of systemic and tumor associated myeloid-derived suppressor cells or regulatory T cells, increased tumor-responsive interferon-γ-producing lymphocytes and tumor-associated CD8+ CXCR3+ T cells, and inhibited proliferation and angiogenesis but stimulated apoptosis within melanoma tissue. This study demonstrates the therapeutic potential of Endoglin-scFv/IP10 fusion protein in combination with CD8+ CD28+ CTLs in melanoma treatment.

Abstract
Diffusion-weighted imaging (DWI) is a functional imaging technique sensitive to microstructure in tissues. It is widely acknowledged to reflect cellularity in tumors. A small part of DWI is also sensitive to perfusion-related information and might therefore be also be able to reflect microvessel density in tumor tissues. Aim of the present study was to elucidate possible correlations between microvessel density and apparent diffusion coefficient (ADC) values in head and neck squamous cell carcinoma (HNSCC).Thirty-four patients with histologically proven primary HNSCC were included in the study. DWI was performed with a 3 T magnetic resonance imaging (MRI) (b-values 0 and 800 s/mm) and histogram analysis was calculated with a whole lesion measurement. In every case, microvessel density was estimated with CD105-stained specimens.There were no statistically significant correlations between ADC histogram parameters and microvessel density. The calculated correlation coefficients ranged from r = -0.27, P = .13 for entropy and vessel area to r = 0.16, P = .40 for ADCmin and vessel count.Whole-lesion histogram analysis of ADC values cannot reflect microvessel density in HNSCC.

Abstract
Based on molecular targeting, magnetic resonance imaging (MRI) is an ideal noninvasive approach for tumor diagnosis. Construction of targeting probes to enhance the MRI efficacy has become a research hotspot recently. In this study, magnetic endoglin aptamer (mEND) imaging nanoprobes based on mEND-modified magnetic carboxymethyl chitosan (CMCS) nanoparticles (denoted mEND-Fe₃O₄@CMCS) were developed. The mEND-Fe₃O₄@CMCS naoprobe was prepared using mEND as the recognition molecule and Fe₃O₄@CMCS as the carrier to enhance the MRI efficacy of hepatocellular carcinoma (HCC). On the one hand, the CMCS self-assembled on the surface of Fe₃O₄ improved the biocompatibility and nontoxicity of magnetic nanoparticles. On the other hand, chemical groups provided by CMCS contributed to the modification of more aptamers. More importantly, the assembled aptamers significantly improved the probe targeting ability, thus enhancing the diagnosis efficacy of MRI of HCC. As a result, the average diameter and zeta potential of the nanoprobe was 87.15±1.66 nm and -31.9±0.5 mV, respectively. The MRI imaging result indicated that this probe effectively targeted neovascularization of mouse HCC and improved the imaging contrast of subcutaneous tumor in mice. Cytotoxicity and histological tests confirmed that the constructed probe possessed low toxicity. In conclusion, the mEND-Fe₃O₄@CMCS nanoprobe showed high targeting affinity, enhanced MRI effect and good biocompatibility. This study provides new MRI probes to target CD105 positive cells and is a promising candidate for HCC early diagnosis.

Abstract
Surgery is the mainstay for treating hepatocellular carcinoma (HCC). However, it is a great challenge for surgeons to identify HCC in its early developmental stage. The diagnostic sensitivity for a tiny HCC with a diameter less than 1.0 cm is usually as low as 10-33% for computed tomography (CT) and 29-43% for magnetic resonance imaging (MRI). Although MRI is the preferred imaging modality for detecting HCC, with its unparalleled spatial resolution for soft tissue, the commercially available contrast agent, such as Gd3+-DTPA, cannot accurately define HCC because of its short circulation lifetime and lack of tumor-targeting specificity. Endoglin (CD105), a type I membrane glycoprotein, is highly expressed both in HCC cells and in the endothelial cells of neovasculature, which are abundant at the tumor periphery. In this work, a novel single-stranded DNA oligonucleotide-based aptamer was screened by systematic evolution of ligands in an exponential enrichment assay and showed a high binding affinity ( KD = 98 pmol/L) to endoglin. Conjugating the aptamers and imaging reporters on a G5 dendrimer created an HCC-targeting nanoprobe that allowed the successful visualization of orthotopic HCC xenografts with diameters as small as 1-4 mm. Significantly, the invasive tumor margin was clearly delineated, with a tumor to normal ratio of 2.7 by near-infrared (NIR) fluorescence imaging and 2.1 by T1-weighted MRI. This multimodal nanoprobe holds promise not only for noninvasively defining tiny HCC by preoperative MRI but also for guiding tumor excision via intraoperative NIR fluorescence imaging, which will probably gain benefit for the patient's therapeutic response and improve the survival rate.

Abstract
Bone deficiencies in the jaws of edentulous patients limit the possibility of successful placement and osseointegration of endosseous implants. Bone resorption is defined as a vertical and horizontal loss of quality and quantity in the residual bone ridges; lack of bone structure requires bone grafting procedures to enable implant placement and to improve the function, predictability, and longevity of implants. The objective of this case study was to demonstrate the feasibility of a novel cell therapy treatment for localized jaw bone defects with tissue repair cells composed of a mixture of bone marrow-derived cells, including CD90+ mesenchymal stem cells and CD105+ monocytes/macrophages, and xenograft blocks, in what would be a safe and efficacious approach to the regeneration of localized craniofacial bone defects. The use of stem cells represents an alternative that could offer improved results, better quality histologically, and greater quantity in millimeters of tissue in bone regeneration.

Abstract
OBJECTIVE To determine (1) whether maternal plasma concentrations of angiogenic and anti-angiogenic factors can predict which mothers diagnosed with "suspected small for gestational age fetuses (sSGA)" will develop pre-eclampsia (PE) or require an indicated early preterm delivery (≤ 34 weeks of gestation); and (2) whether risk assessment performance is improved using these proteins in addition to clinical factors and Doppler parameters. METHODS This prospective cohort study included women with singleton pregnancies diagnosed with sSGA (estimated fetal weight <10th percentile) between 24 and 34 weeks of gestation (n = 314). Plasma concentrations of soluble vascular endothelial growth factor receptor-1 (sVEGFR-1), soluble endoglin (sEng) and placental growth factor (PlGF) were determined in maternal blood obtained at the time of diagnosis. Doppler velocimetry of the umbilical (Umb) and uterine (UT) arteries was performed. The outcomes were (1) subsequent development of PE; and (2) indicated preterm delivery at ≤ 34 weeks of gestation (excluding deliveries as a result of spontaneous preterm labor, preterm pre-labor rupture of membranes or chorioamnionitis). RESULTS (1) The prevalence of PE and indicated preterm delivery was 9.2% (n = 29/314) and 7.3% (n = 23/314), respectively; (2) the area under the receiver operating characteristic curve (AUC) for the identification of patients who developed PE and/or required indicated preterm delivery was greater than 80% for the UT artery pulsatility index (PI) z-score and each biochemical marker (including their ratios) except sVEGFR-1 MoM; (3) using cutoffs at a false positive rate of 15%, women with abnormal plasma concentrations of angiogenic/anti-angiogenic factors were 7-13 times more likely to develop PE, and 12-22 times more likely to require preterm delivery than those with normal plasma MoM concentrations of these factors; (4) sEng, PlGF, PIGF/sEng and PIGF/sVEGFR-1 ratios MoM, each contributed significant information about the risk of PE beyond that provided by clinical factors and/or Doppler parameters: women who had low MoM values for these biomarkers were at 5-9 times greater risk of developing PE than women who had normal values, adjusting for clinical factors and Doppler parameters (adjusted odds ratio for PlGF: 9.1, PlGF/sEng: 5.6); (5) the concentrations of sVEGFR-1 and PlGF/sVEGFR-1 ratio MoM, each contributed significant information about the risk of indicated preterm delivery beyond that provided by clinical factors and/or Doppler parameters: women who had abnormal values were at 8-9 times greater risk for indicated preterm delivery, adjusting for clinical factors and Doppler parameters; and (6) for a two-stage risk assessment (Umb artery Doppler followed by Ut artery Doppler plus biochemical markers), among women who had normal Umb artery Doppler velocimetry (n = 279), 21 (7.5%) developed PE and 11 (52%) of these women were identified by an abnormal UT artery Doppler mean PI z-score (>2SD): a combination of PlGF/sEng ratio MoM concentration and abnormal UT artery Doppler velocimetry increased the sensitivity of abnormal UT artery Doppler velocimetry to 76% (16/21) at a fixed false-positive rate of 10% (p = 0.06). CONCLUSION Angiogenic and anti-angiogenic factors measured in maternal blood between 24 and 34 weeks of gestation can identify the majority of mothers diagnosed with "suspected SGA" who subsequently developed PE or those who later required preterm delivery ≤ 34 weeks of gestation. Moreover, incorporation of these biochemical markers significantly improves risk assessment performance for these outcomes beyond that of clinical factors and uterine and umbilical artery Doppler velocimetry.

Abstract
OBJECTIVE Basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF) are involved in the pathogenesis of leiomyomas and influence angiogenesis, which is necessary for growth of leiomyomas. Gonadotropin-releasing hormone analogue (GnRH-a) treatment might modify the growth factor expression and the blood supply in myomas. We investigated the effects of GnRH-a treatment on some clinical parameters, on the immunohistochemical expression of bFGF, VEGF, and PDGF, and on the vasculature of leiomyomas. METHODS Thirty-one women were treated with leuprolide acetate for 3 months; 55 untreated patients formed the control group. Hematologic parameters were assessed at the admission, after GnRH-a treatment, and after surgery. Uterine volume was evaluated by ultrasonography. The immunoexpression of bFGF, VEGF, and PDGF and of the endothelial markers CD34 and CD105, as well as the vascular pattern, were studied in leiomyomas, comparing treated and untreated patients. RESULTS Hematologic parameters improved and uterine volumes decreased after GnRH-a treatment. The immunoexpression of bFGF, VEGF, and PDGF decreased in treated myomas, together with the total number of vessels and the angiogenetic vessels. CONCLUSION This study confirms the clinical response of uterine shrinkage after GnRH-a treatment. A pathogenetic role of bFGF, VEGF, and PDGF in myoma growth and vascularization is suggested. Finally, this study indirectly confirms the importance of the vasculature in leiomyoma growth.

Abstract
Hereditary hemorrhagic telangiectasia (HHT) is a hereditary condition that results in vascular malformations throughout the body, which have a proclivity to rupture and bleed. HHT has a worldwide incidence of about 1:5000 and approximately 80 % of cases are due to mutations in ENG, ALK1 (aka activin receptor-like kinase 1 or ACVRL1) and SMAD4. Over 200 international clinicians and scientists met at Captiva Island, Florida from June 11-June 14, 2015 to present and discuss the latest research on HHT. 156 abstracts were accepted to the meeting and 60 were selected for oral presentations. The first two sections of this article present summaries of the basic science and clinical talks. Here we have summarized talks covering key themes, focusing on areas of agreement, disagreement, and unanswered questions. The final four sections summarize discussions in the Workshops, which were theme-based topical discussions led by two moderators. We hope this overview will educate as well as inspire those within the field and from outside, who have an interest in the science and treatment of HHT.

Abstract
BACKGROUND/AIMS A link between the number of podocytes excreted in the urine and activity of glomerular disease has been established. The aim of this study was to investigate possible correlations between urinary cells' phenotype and the progression of focal segmental glomerulosclerosis (FSGS). METHODS Forty patients with newly diagnosed FSGS were included. Cells were isolated from urine by adherence to collagen-coated cover slips and assessed for the expression of podocalyxin (PDX), CD68 and Ki67 antigens by indirect immunofluorescence. In addition, double-staining procedures were performed in combinations of the above antigens plus cytokeratin, WT1 and CD-105. Twenty-two patients in whom urinary protein to creatinine ratio exceeded 2.0 at diagnosis were followed for 36 months, with assessments of renal function and proteinuria every 3 months. During observation, patients were subjected to standard therapy. RESULTS Significantly higher numbers of Ki67 positive cells at the onset of the study were observed in patients who have doubled serum creatinine (SCr) in follow-up, than in those who have not (p = 0.0149). By logistic regression analysis, both CD68 and Ki67, but not anti-PDX positive cell numbers at diagnosis were found to be predictors of doubling SCr concentration in 36 months' follow-up. Results of double staining indicate that PDX positive cells could be identified as podocytes or their precursors and parietal epithelial cells. CONCLUSION Urinary sediment PDX positive cell numbers do not predict the progression of FSGS, whereas CD68 and Ki67 phenotype of urinary podocytic lineage clearly has a prognostic significance in 36 months' observation of primary FSGS.

Abstract
Mast cells proteases, tryptase and chymase are directly involved in the growth and progression of solid tumors due to their important role in tumor angiogenesis. We examined the density of tryptase positive mast cells and the mean density of new blood vessels in gastric malignant tumors of patients with and without Helicobacter pylori infection, using immunohistochemical staining for tryptase (for mast cells) and CD 105 (for new vessels). Tryptase and CD 105 expression was detected in gastrectomy specimens. In this study, mast cell density correlates with angiogenesis and the growth and progression of gastric cancer. It also shows that the participation of Helicobacter pylori infection in the growth and progress of gastric neoplasia is due to an increase of peritumoral angiogenesis, with subsequent local and distant tumor spread and perivascular growth, but without perineural and nodal involvement.

Abstract
OBJECTIVE Diabetic peripheral neuropathy is a common complication of type-2 diabetes mellitus. Endocan, apelin and endoglin are thought to be associated with endothelial dysfunction, angiogenesis and inflammation. In this study, we planned to evaluate these markers in diabetic peripheral neuropathy patients. PATIENTS AND METHODS This single-blind, controlled clinical study was conducted on 99 type 2 diabetic patients with or without diabetic peripheral neuropathy and 53 healthy volunteer controls. Physical and laboratory examinations were done in all groups. In these groups, Endoglin, apelin and endocan levels were measured with ELISA method. RESULTS Endoglin, apelin and endocan concentrations in diabetic peripheral neuropathy patients were higher than other diabetes mellitus patients and healthy controls. Similarly, diabetes mellitus patient's endoglin, apelin and endocan levels were higher than healthy controls. The differences were statistically significant. We detected a significant positive correlation between endoglin, apelin and endocan levels in all groups. CONCLUSIONS Endoglin, apelin and endocan may reflect angiogenesis and endothelial dysfunction in diabetic peripheral neuropathy and they may be used as a marker in the future.

Abstract
There is recent interest for uniform placental collection protocols so laboratories can share samples. However, concerns have been raised a wash step at collection causes significant loss of sFlt-1 and soluble endoglin, among the most studied proteins in placentology. We measured Flt-1 and endoglin mRNA and protein in 10 preeclamptic placentas that were washed, or left unwashed. Reassuringly, there was no significant change in the Flt-1, sFlt-1-e15a or sFlt-1-i13 mRNA or Flt-1 or sFlt-1 protein expression or localization. There was also no change in endoglin mRNA expression or protein localization. Washing preeclamptic placental samples does not alter anti-angiogenic factor expression.

Abstract
CONTEXT There is an abnormal increase in TGF-β1 bioavailability in women with polycystic ovary syndrome (PCOS), which might play a role in the pathophysiology of this syndrome. Vitamin D (VD) supplementation improves various clinical manifestations of PCOS and decreases TGF-β1 levels in several diseases including myelofibrosis. OBJECTIVE The objective of the study was to determine the effect of VD supplementation on TGF-β1 bioavailability in VD-deficient women with PCOS and assess whether changes in TGF-β1/soluble endoglin (sENG) levels correlate with an improvement in PCOS clinical manifestations. DESIGN This was a prospective, randomized, placebo-controlled trial. SETTING The study was conducted at an academic-affiliated medical center. PARTICIPANTS Sixty-eight VD-deficient women with PCOS who were not pregnant or taking any exogenous hormones were recruited between October 2013 and January 2015. INTERVENTIONS Forty-five women received 50 000 IU of oral vitamin D3 and 23 women received oral placebo once weekly for 8 weeks. MAIN OUTCOMES MEASURES Serum TGF-β1, sENG, lipid profile, testosterone, dehydroepiandrosterone sulfate, and insulin resistance were measured. The clinical parameters were evaluated before and 2 months after treatment. RESULTS The VD level significantly increased and normalized after VD supplementation (16.3 ± 0.9 [SEM] to 43.2 ± 2.4 ng/mL; P < .01), whereas it did not significantly change after placebo. After the VD supplementation, there was a significant decrease in the following: the interval between menstrual periods (80 ± 9 to 60 ± 6 d; P = .04), Ferriman-Gallwey score (9.8 ± 1.5 to 8.1 ± 1.5; P < .01), triglycerides (138 ± 22 to 117 ± 20 mg/dL; P = .03), and TGF-β1 to sENG ratio (6.7 ± 0.4 to 5.9 ± 0.4; P = .04). In addition, the ΔTGF-β1 to sENG ratio was positively correlated with Δtriglycerides (r = 0.59; P = .03). CONCLUSIONS VD supplementation in VD-deficient women with PCOS significantly decreases the bioavailability of TGF-β1, which correlates with an improvement in some abnormal clinical parameters associated with PCOS. This is a novel mechanism that could explain the beneficial effects of VD supplementation in women with PCOS. These findings may support new treatment modalities for PCOS, such as the development of anti-TGF-β drugs.

Abstract
GOALS To identify putative angiogenic factors associated with sporadic small bowel angiodysplasia (SBA). BACKGROUND SBAs account for 50% of obscure gastrointestinal bleeding and due to delays in diagnosis and ineffective treatments, are associated with high levels of morbidity and mortality. Treatment development is impeded by a limited knowledge of the pathophysiology behind SBA formation. STUDY We identified patients with definite sporadic SBA, and fecal immunochemical-negative controls were recruited from our institution's colorectal cancer screening program. Serum levels of VEGF, endoglin, Angiopoietin-2 (Ang-2), PDGF, Angiopoietin-1 (Ang-1), and TNF-α were measured using commercially available enzyme-linked immunosorbent assay kits. On the basis of serum results, we measured gene expression of target angiogenic factors in small bowel biopsy samples from angiodysplasias and unaffected tissue by quantitative PCR assessment. RESULTS Serum samples were analyzed from 40 SBA patients and 40 controls. Median serum levels of Ang-2 were significantly higher in patients than controls with levels of Ang-1 and TNF-α significantly lower. There were no differences in serum levels of VEGF, endoglin, or PDGF. Gene expression levels of Ang-1, Ang-2, and their receptor Tie2 were all significantly higher in biopsies from areas of angiodysplasia compared with normal small bowel. CONCLUSIONS This study, the first to explore the role of angiogenic factors in SBA, has identified a positive association between SBA and the Angiopoietin pathway, with increased serum and mucosal expression of Ang-2, which could potentially be used as a serum biomarker and future therapeutic target to improve outcome in affected patients.

Abstract
BACKGROUND AND OBJECTIVE Unlike normal tissue-derived microvascular endothelial cells, tumor microvessel endothelial cells are highly reactive to growth factors and exhibit more adhesion molecules. Thus, vascular tumors are highly permeable and grow vigorously; this occurrence results in rapid growth and metastasis cancer cells. Therefore, understanding the characteristics of endothelial cells in the tumor microenvironment guides anti-angiogenic therapy. To this end, we explore the effect of the supernatant obtained from cultured Anip973 cells (high-metastatic human lung adenocarcinoma cells) on the biological behavior and on the cell surface markers of the human umbilical vein endothelial cell (HUVEC). METHODS The HUVEC that was cultured in a medium (RPMI-1640 + 10% fetal bovine serum) containing various concentrations of Anip973 supernatants was categorized into experimental groups. The HUVEC cultured in a medium without Anip973 supernatants served as the control group. Proliferation was determined with CCK-8; blood vessel formation was investigated with three-dimensional culture techniques in vitro; and HUVEC migration was observed via transwell assay. At the same time, the expressions of CD105, CD31, and the apoptotic marker of Annexin V were detected through flow cytometry for analyzing the relationship between the expression of cell surface markers and biological behavior. RESULTS Following incubation with the supernatant obtained from cultured Anip973 cells, HUVEC proliferated more than the control group did, and the proliferation rate was maximized when incubated in a supernatant concentration of 250 μL/mL for 24 h (P=0.002). In addition, the experimental groups exhibited varying degrees of migration and forms of vascular lumen sample structure, especially at supernatant concentrations of 125 µL/mL (P<0.001) and 250 µL/mL (P=0.002), respectively. CD105 expression was optimized at 250 μL/mL (P=0.028), and CD31 expression also increased with an increase in concentration. However, the percentage of apoptotic cells decreased. Correlation analysis results showed that cell proliferation, migration, and CD105 expression were significantly and positively correlated with one another. By contrast, no significant correlation was detected between CD31 expression and biological behavior. CONCLUSIONS Anip973 supernatants can promote HUVEC proliferation and migration, as well as angiogenesis. In addition, cell surface markers can change concurrently and relatively. To a certain extent, changes in CD105 expression can be attributed to shifts in its biological behavior.

Abstract
Endoglin is an essential molecule during angiogenesis, vascular development, and integrity. Till now, many studies have investigated the association between endoglin polymorphisms and intracranial aneurysm (IA) risk, with the results remained inconclusive. Therefore, we performed a meta-analysis to summarize the possible association.We searched PubMed and Embase until June 2015 to identify studies addressing the association between endoglin polymorphisms and IA risk. The summary odds ratios (ORs) and their corresponding 95% confidence interval (CI) were calculated to assess the strength of the association.Eleven studies with a total of 1501 cases and 2012 controls were finally included in this meta-analysis, with 10 studies investigating endoglin 6-bp insertion (6bINS) polymorphism and 4 studies investigating 1800956 polymorphism. No significant association between endoglin 6bINS polymorphism and IA risk was detected in overall estimation (I/I vs wt/I + wt/wt: OR = 1.21, 95% CI = 0.87-1.69) or in the subgroup analysis by ethnicity, control source, or ruptured status. However, we observed an association with borderline significance of 6bINS with IA occurrence (I/I vs wt/I + wt/wt: OR = 1.49, 95% CI = 0.99-2.25, P = 0.058) in studies applying matched controls. Furthermore, we detected a significant association for 6bINS polymorphism of endoglin with increased risk of familial IA (I vs wt, OR = 1.64, 95% CI = 1.10-2.42) but not sporadic IA (I vs wt, OR = 1.09, 95% CI = 0.68-1.45). With regard to rs1800956, our pooled results indicated a significantly decreased IA risk in individuals carrying C allele (C/C vs G/C + G/G: OR = 0.65; 95% CI = 0.45-0.94).This meta-analysis provided no evidence for the association between 6bINS polymorphism with overall IA risk. However, we detected a significant association of 6bINS allele with increased risk of familial IA. Also, we found that rs1800956 was significantly related to IA occurrence. Further, well-designed studies with large sample size are warranted and updated meta-analysis is needed to verify our findings.

Abstract
Preeclampsia is a serious complication of pregnancy with no medical treatment. It is caused by intermittent placental hypoxia and release of sFlt-1 and soluble endoglin, leading to wide spread maternal endothelial dysfunction and multisystem organ injury. YC-1 is a guanylyl cyclase activator and HIF1α inhibitor developed for use in hypertension and atherosclerosis. We examined whether YC-1 reduces sFlt-1 and sENG secretion and reverses endothelial dysfunction in primary human tissues. YC-1 significantly reduced sFlt-1 and sENG secretion from human umbilical vein endothelial cells, purified primary trophoblast cells and placental explants taken from patients with preterm preeclampsia. This was concordant with reduced HIF1α expression. YC-1 also reversed TNFα induced endothelial dysfunction, including reduced vascular cell adhesion molecule 1 expression and monocyte adhesion to primary endothelial cells. We conclude YC-1 decreases placental production of sFlt-1 and sENG and decreases endothelial dysfunction. It is a novel therapeutic candidate for preeclampsia.

Abstract
Background Diagnosing pediatric pneumonia is challenging in low-resource settings. The World Health Organization (WHO) has defined primary end-point radiological pneumonia for use in epidemiological and vaccine studies. However, radiography requires expertise and is often inaccessible. We hypothesized that plasma biomarkers of inflammation and endothelial activation may be useful surrogates for end-point pneumonia, and may provide insight into its biological significance. Methods We studied children with WHO-defined clinical pneumonia (n = 155) within a prospective cohort of 1,005 consecutive febrile children presenting to Tanzanian outpatient clinics. Based on x-ray findings, participants were categorized as primary end-point pneumonia (n = 30), other infiltrates (n = 31), or normal chest x-ray (n = 94). Plasma levels of 7 host response biomarkers at presentation were measured by ELISA. Associations between biomarker levels and radiological findings were assessed by Kruskal-Wallis test and multivariable logistic regression. Biomarker ability to predict radiological findings was evaluated using receiver operating characteristic curve analysis and Classification and Regression Tree analysis. Results Compared to children with normal x-ray, children with end-point pneumonia had significantly higher C-reactive protein, procalcitonin and Chitinase 3-like-1, while those with other infiltrates had elevated procalcitonin and von Willebrand Factor and decreased soluble Tie-2 and endoglin. Clinical variables were not predictive of radiological findings. Classification and Regression Tree analysis generated multi-marker models with improved performance over single markers for discriminating between groups. A model based on C-reactive protein and Chitinase 3-like-1 discriminated between end-point pneumonia and non-end-point pneumonia with 93.3% sensitivity (95% confidence interval 76.5–98.8), 80.8% specificity (72.6–87.1), positive likelihood ratio 4.9 (3.4–7.1), negative likelihood ratio 0.083 (0.022–0.32), and misclassification rate 0.20 (standard error 0.038). Conclusions In Tanzanian children with WHO-defined clinical pneumonia, combinations of host biomarkers distinguished between end-point pneumonia, other infiltrates, and normal chest x-ray, whereas clinical variables did not. These findings generate pathophysiological hypotheses and may have potential research and clinical utility.

Abstract
Background Vascular patterning depends on coordinated timing of arteriovenous specification of endothelial cells and the concomitant hemodynamic forces supplied by the onset of cardiac function. Using a combination of 3D imaging by OPT and embryo registration techniques, we sought to identify structural differences between three different mouse models of cardiovascular perturbation. Results Endoglin mutant mice shared a high degree of similarity to Mlc2a mutant mice, which have been shown to have a primary developmental heart defect causing secondary vessel remodeling failures. Dll4 mutant mice, which have well-characterized arterial blood vessel specification defects, showed distinct differences in vascular patterning when compared to the disruptions seen in Mlc2a-/- and Eng-/- models. While Mlc2a-/- and Eng-/- embryos exhibited significantly larger atria than wild-type, Dll4-/- embryos had significantly smaller hearts than wild-type, but this quantitative volume decrease was not limited to the developing atrium. Dll4-/- embryos also had atretic dorsal aortae and smaller trunks, suggesting that the cardiac abnormalities were secondary to primary arterial blood vessel specification defects. Conclusions The similarities in Eng-/- and Mlc2a-/- embryos suggest that Eng-/- mice may suffer from a primary heart developmental defect and secondary defects in vessel patterning, while defects in Dll4-/- embryos are consistent with primary defects in vessel patterning.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is known as one of the most malignant potential diseases with poor neovascularization. By comparing PDAC to hepatocellular carcinoma (HCC), which is well vascularized, we investigated the mechanisms and tumor biological significance of the poor neovascularization in PDAC. METHODS Surgical specimens from primary PDAC and HCC patients were immunohistologically stained to detect the expressions of CD105, CD44, HIF-1α, PHD3, and Siah2. We also used two PDAC and two HCC cell lines to compare the expressions of HIF-1α, PHD3, and CD44, as well as the production of VEGF in hypoxic condition. The role of PHD3 in regulating HIF-1α expression was further confirmed by siRNA knockdown in a PDAC cell line that highly expressed PHD3. RESULTS There were significantly fewer microvessels but more cancer stem cells in PDAC specimens compared to HCC specimens. The expression of CD105 was reversely related to the expression of CD44 in PDAC and HCC specimens. PDAC specimens also showed higher expressions of PHD3 but lower expressions of HIF-1α. Similarly, the expression of PHD3 was observed clearly in PDAC cell lines, but was almost completely negative in HCC cell lines. Hypoxic stimulation clearly enhanced HIF-1α expression and VEGF secretion in both HCC cell lines, but did not significantly change in PDAC cell lines. The knockdown of PHD3 in PDAC cells restored the hypoxic-induced HIF-1α expression, which accordingly stimulated the cells' VEGF secretion. CONCLUSIONS The enhanced expression of PHD3 might likely contribute to the poor neovascularization and affect the biological characterization in PDAC cancer cells.

Abstract
The aim of this study was to investigate the expression of Delta-like ligand 4(DLL4) and Endoglin(CD105) labeled microvessel density(MVD) in pancreatic ductal adenocarcinoma (PDAC) and evaluate their correlation with major clinicopathologic features and patients' survival. Forty-two pancreatic cancer and 20 normal pancreatic tissues were included in the study. Immunohistochemical staining was employed to assess the expression level of DLL4 both in tumor cells and stromal vascular endothelial cells, as well as CD105 which was used to determine MVD. The relationships of DLL4 and CD105 expression with clinicopathologic parameters and clinical outcome were evaluated. Both DLL4 and CD105-labeled microvessel were observed highly immunostained in PDAC cases, and high expression of DLL4 was positively correlated with MVD. Moreover, the high expression of DLL4 was significantly associated with histological grade, node stage and TNM stage in not only the cancer cells but also stroma; while high expression of CD105 was associated with histological grade, TNM stage, node stage and distant metastasis. In univariant analysis, patients with high expression of DLL4 and CD105 tended to significantly poorer overall survival. Both DLL4 and CD105 were overexpressed in a large proportion of patients with PDAC. The expression of DLL4 was positively correlated with CD105-labeled MVD, indicating DLL4 may involved in angiogenesis. In addition, high DLL4 and CD105 expression correlated with the poor clinical outcome and overall survival in patients with PDAC.

Abstract
Research Question Preterm birth (PTB) is the leading cause of perinatal mortality worldwide, with the greatest burden occurring in resource-constrained settings. Based on the hypothesis that altered placental angiogenesis and inflammation early in pregnancy lead to PTB, we examined whether levels of inflammatory and angiogenic mediators, measured early in pregnancy, were predictive of spontaneous PTB (sPTB). Study Design Plasma samples were collected from a prospective cohort of primigravid Tanzanian women between 12–27 weeks gestation. A panel of 18 markers was screened on a training cohort of 426 women. Markers associated with sPTB in the training cohort were repeated in a test cohort of 628 women. All markers were measured by ELISA. Findings In both the training and test cohorts plasma levels of IL-18BP, sICAM-1, sEndoglin and CHI3L1 were elevated and Leptin was lower at enrollment in women who subsequently experienced sPTB. In multivariate analysis women with plasma levels of CHI3L1, C5a, sICAM-1, AngptL3, sEndgolin, sFlt-1 and IL-18BP in the highest quartile had an increased risk of sPTB compared with those in the lowest quartile. Women with Leptin and Ang2 in the highest quartile had a reduced risk of sPTB compared with women in the lowest quartile. Implications Levels of angiogenic and inflammatory mediators measured at mid-pregnancy were associated with subsequent sPTB. These findings provide insight into mechanisms underlying sPTB and suggest biomarkers that may have clinical utility in risk-stratifying pregnancies.

Abstract
AIM: To evaluate the correlation between the immunoexpression of angiogenic markers [CD31, CD105 and vascular endothelial growth factor (VEGF)], proliferative index (Ki67), and prognosis of patients with gastrointestinal stromal tumors (GIST).
METHODS: This is a retrospective study of 54 GIST cases. Medical records were searched to obtain the GIST patients’ demographic and clinical data, and paraffin-embedded blocks of tumor samples were retrieved from the hospital archives to conduct a new immunohistochemical evaluation. The tumor samples of GIST patients were subject to immunohistochemical evaluation for endoglin (CD105), CD31, VEGF, and Ki67 expression. The CD105 and CD31 intratumoral microvascular density (IMVD) was measured using automated analysis. We determined the correlation between the immunoexpression of CD105, CD31, VEGF, Ki67 and prognosis. In addition, we conducted a cutoff analysis using the receiver-operating characteristic curve. VEGF positivity was classified as either null/weak or strong. Ki67 was evaluated using a cutoff of 5% positive cells. The prognosis was classified as good (patient alive without recurrence) or poor (patient with recurrence/death).
RESULTS: The distribution of tumor sites among the 54 analyzed samples was as follows: 27 (50%) in the stomach, 20 (37.1%) in the small intestine, 6 (11.1%) in the colon, and 1 (1.8%) in the esophagus. The size of the tumors ranged from 2 to 33 cm (median: 8 cm); in 12 cases (22.2%), the tumor was below 5 cm at the largest diameter, but in 42 cases (77.7%), the tumor was larger than 5 cm. The means of CD105 and CD31 were significantly higher in the group with poor prognosis (P < 0.001). The cut-off values of CD105 (> 1.2%) and CD31 (> 2.5%) in the receiver-operating characteristic curve were related to a poorer prognosis. Cases with a better prognosis showed significantly null/weak staining for VEGF (P < 0.001). Ki-67 expression of ≥ 5% was strongly correlated with a worse prognosis (P < 0.001). In the multivariate analysis, CD105 was the variable that most strongly correlated with prognosis.
CONCLUSION: The IMVD cutoff values for the angiogenic markers CD105 and CD31, may be prognostic factors for GIST, in addition to VEGF and Ki67.

Abstract
Elevated levels of circulating angiogenic cytokines and increased expression of genes encoding angiogenic factors have been reported in recent years in patients with chronic lymphocytic leukemia (CLL) but data regarding prognostic and predictive significance are still limited. Therefore, in the present study based upon our prior pilot results, we measured mRNA expressions of angiopoietin-2 (Ang-2), fibroblast growth factor-2 (FGF-2) and endoglin (CD105) by reverse transcription quantitative PCR in purified CD19+ cells from 70 untreated CLL patients (median age, 63 years; males, 64%; Rai III/IV stages, 29 %; unmutated IgVH genes, 60 %) and evaluated their possible association with established prognostic factors and clinical course of the disease. Higher expression of Ang-2 was significantly associated with unmutated IgVH genes (n = 55, p = 0.003). Higher CD105 expression was significantly associated with unmutated IgVH genes (n = 55, p < 0.001), high CD38 expression (n = 66, p = 0.022), high ZAP-70 expression (n = 66, p = 0.010), Rai stage I-IV (n = 70, p < 0.001), progressive clinical course of CLL (n = 70, p = 0.001) and shorter time to treatment (n = 70; p < 0.001). Expression of FGF-2 was not significantly associated with any of the prognostic markers. These results indicate that elevated expression of Ang-2 and in particular CD105 by CLL cells is associated with unfavorable prognostic features and clinical outcome; thus, both cytokines appear to play an important role in biology and progression of CLL and warrant further investigation.

Abstract
AIM High glucose-induced oxidative stress has been suggested as one of the mediators of endothelial damage in diabetes. The major endothelial protein, endoglin, has been found overexpressed in the vessels during pathological situations, but little is known about its relation to diabetic vascular complications. To clarify the role of endoglin in endothelial injury, we sought to determine the effects of high and oscillating glucose on its expression. MATERIALS Furthermore, the activation of the Krüppel-like factor 6 (KLF-6) and the hypoxia-inducible factor-1α (HIF-1α) as possible regulators of endoglin expression has been evaluated. The possible role of the oxidative stress has been studied evaluating the effects of the antioxidant alpha-lipoic acid (ALA) and the cellular antioxidant response mediated by NAD(P)H quinine-oxido-reductase-1 (NQO-1) and heme oxygenase-1 (HO-1). RESULTS Primary HUVECs were cultured for 21 days in normal, high and oscillating glucose (5, 25 and 5/25 mmol/l every 24 h, respectively) with/without ALA. In oscillating and high glucose total endoglin, its soluble form (sEng), KLF-6 and HIF-1α were significantly increased. Simultaneously, the oxidative DNA stress markers 8-OHdG and H2A.X were elevated. Moreover, ENG gene transcriptional rate increased during glucose exposures concomitantly with increased KLF-6 nuclear translocations. ALA significantly reduced all these phenomena. Interestingly, during oscillating and chronic high glucose, NQO-1 and HO-1 did not increase, but ALA induced their overexpression. CONCLUSIONS Together, these findings provide novel clue about endoglin in the regulation of high glucose-mediated vascular damage in HUVECs and the role of oxidative stress in this regulation.

Abstract
Endoglin, a transforming growth factor β (TGF-β) receptor type III, is co-expressed with endothelial nitric oxide synthase (eNOS) in aortic endothelium in atherosclerotic plaques of mice. Interestingly, atorvastatin (ATV) is able to increase both endoglin and eNOS expression and reduce plaque size beyond its lipid lowering effects but by unknown mechanisms. We hypothesized whether inflammation modulates ATV-dependent induction of endoglin and eNOS expression in vitro in endothelial cells and whether ATV-induced eNOS expression is regulated via endoglin. After treatment of human umbilical vein endothelial cells (HUVECs) with TNF-α, endoglin and eNOS protein expression was reduced, concomitantly with increased levels of cell surface VCAM-1 and soluble endoglin, as determined by flow cytometry, Western blot and ELISA analyses. By contrast, ATV treatment increased endoglin and eNOS protein expression, while preventing TNF-α-mediated downregulation of endoglin and eNOS protein levels. Moreover, suppression of endoglin using small interfering RNA (siRNA), but not inhibition of TGF-β signaling with SB431542, abrogated ATV-induced eNOS expression. These results suggest that ATV treatment prevents inflammation-reduced endoglin and eNOS expression in endothelial cells and that ATV-induced eNOS expression strongly depends on the proper expression of endoglin in HUVECs. Possible implications of these findings might be reflected in pathological conditions characterized by reduced expression of endoglin and eNOS as for example in hereditary hemorrhagic telangiectasia or in other endothelial dysfunctions.
