[Ti] Título:Doxycycline modulates VEGF-A expression: Failure of doxycycline-inducible lentivirus shRNA vector to knockdown VEGF-A expression in transgenic mice.

[Ab] Resumo:Vascular endothelial growth factor-A (VEGF-A) is the master regulator of angiogenesis, vascular permeability and growth. However, its role in mature blood vessels is still not well understood. To better understand the role of VEGF-A in the adult vasculature, we generated a VEGF-A knockdown mouse model carrying a doxycycline (dox)-regulatable short hairpin RNA (shRNA) transgene, which silences VEGF-A. The aim was to find the critical level of VEGF-A reduction for vascular well-being in vivo. In vitro, the dox-inducible lentiviral shRNA vector decreased VEGF-A expression efficiently and dose-dependently in mouse endothelial cells and cardiomyocytes. In the generated transgenic mice plasma VEGF-A levels decreased shortly after the dox treatment but returned back to normal after two weeks. VEGF-A expression decreased shortly after the dox treatment only in some tissues. Surprisingly, increasing the dox exposure time and dose led to elevated VEGF-A expression in some tissues of both wildtype and knockdown mice, suggesting that dox itself has an effect on VEGF-A expression. When the effect of dox on VEGF-A levels was further tested in naïve/non-transduced cells, the dox administration led to a decreased VEGF-A expression in endothelial cells but to an increased expression in cardiomyocytes. In conclusion, the VEGF-A knockdown was achieved in a dox-regulatable fashion with a VEGF-A shRNA vector in vitro, but not in the knockdown mouse model in vivo. Dox itself was found to regulate VEGF-A expression explaining the unexpected results in mice. The effect of dox on VEGF-A levels might at least partly explain its previously reported beneficial effects on myocardial and brain ischemia. Also, this effect on VEGF-A should be taken into account in all studies using dox-regulated vectors.

[Ti] Título:VEGF may contribute to macrophage recruitment and M2 polarization in the decidua.

[Ab] Resumo:It is increasingly evident that cytokines and growth factors produced in the decidua play a pivotal role in the regulation of the local immune microenvironment and the establishment of pregnancy. One of the major growth factors produced in the decidua is vascular endothelial growth factor (VEGF), which acts not only on endothelial cells, but also on multiple other cell types, including macrophages. We sought to determine whether decidua-derived VEGF affects macrophage recruitment and polarization using human endometrial/decidual tissue samples, primary human endometrial stromal cells (ESCs), and the human monocyte cell line THP1. In situ hybridization was used for assessment of local VEGF expression and immunohistochemistry was used for identification and localization of CD68-positive endometrial macrophages. Macrophage migration in culture was assessed using a transwell migration assay, and the various M1/M2 phenotypic markers and VEGF expression were assessed using quantitative real-time PCR (qRT-PCR). We found dramatic increases in both VEGF levels and macrophage numbers in the decidua during early pregnancy compared to the secretory phase endometrium (non-pregnant), with a significant increase in M2 macrophage markers, suggesting that M2 is the predominant macrophage phenotype in the decidua. However, decidual samples from preeclamptic pregnancies showed a significant shift in macrophage phenotype markers, with upregulation of M1 and downregulation of M2 markers. In THP1 cultures, VEGF treatment significantly enhanced macrophage migration and induced M1 macrophages to shift to an M2 phenotype. Moreover, treatment with conditioned media from decidualized ESCs induced changes in macrophage migration and polarization similar to that of VEGF treatment. These effects were abrogated by the addition of a potent VEGF inhibitor. Together these results suggest that decidual VEGF plays a significant role in macrophage recruitment and M2 polarization, and that inhibition of VEGF signaling may contribute to the shift in macrophage polarity observed in different pregnancy disorders, including preeclampsia.

[Ab] Resumo:In this study, we aimed to observe whether curcumin (cur), a polyphenolic compound derived from the dietary spice turmeric, a yellow substance obtained from the root of the plant Curcuma longa Linn, has any protective effect against blue light irradiation in human retinal pigment epithelium (ARPE-19) cells. For this purpose, we evaluated the intracellular calcium release mechanism, poly ADP ribose polymerase (PARP), procaspase-3/-9 protein expression levels, caspase activation, and reactive oxygen species levels. ARPE-19 cells were divided into four main groups, such as control, cur, blue light, and cur + blue light. Results were evaluated by Kruskal-Wallis and Mann-Whitney U tests as post hoc tests. The cells in cur and cur + blue light samples were incubated with 20 µM cur. Blue light exposure was performed for 24 h in an incubator. Lipid peroxidation and cytosolic-free Ca [Ca ] concentrations were higher in the blue light exposure samples than in the control samples; however, their levels were determined as significantly lower in the cur and cur + blue light exposure samples than in the blue light samples alone. PARP and procaspase-3 levels were significantly higher in blue light samples. Cur administration significantly decreased PARP and procaspase-3 expression levels. Reduced glutathione and glutathione peroxidase values were lower in the blue light exposure samples, although they were higher in the cur and cur + blue light exposure samples. Caspase-3 and -9 activities were lower in the cur samples than in the blue light samples. Moreover, vascular endothelial growth factor (VEGF) levels were significantly higher in the blue light exposure samples. In conclusion, cur strongly induced regulatory effects on oxidative stress, intracellular Ca levels, VEGF levels, PARP expression levels, and caspase-3 and -9 values in an experimental oxidative stress model in ARPE-19 cells.

[Ab] Resumo:PURPOSE: Cigarette smoke is a complex mixture of various chemical compounds, including free radicals and highly toxic compounds. Cigarette smoke exposure has been shown to be associated with chronic rhinosinusitis and tissue remodeling in upper airway. Vascular endothelial growth factor (VEGF) is one of the cytokines with a crucial role in tissue remodeling of airway. The aims of this study were to determine the effects of cigarette smoke extract (CSE) on VEGF expression and to investigate the underlying molecular mechanisms of CSE in nasal fibroblasts. METHODS: Nasal fibroblasts were stimulated with CSE. Cytotoxicity was evaluated by 3-(4,5- dimethylthiazol-2yl)-2,5-diphenyl-tetrazolium bromide assay. The expression level of VEGF was measured using reverse transcription-polymerase chain reaction (RT-PCR), and enzyme-linked immunosorbent assay. Messenger RNA (mRNA) expression level of TLR4 were determined by RT-PCR. Small interfering RNA (siRNA) for TLR4 was transfected to suppress TLR4 expression. Activation of reactive oxygen species (ROS) was analyzed by using dichloro-dihydro-fluorescein diacetate assay. Mitogen-activated protein kinase (MAPK) and NF-kappaB activations were determined by using western blot and/or luciferase assay. RESULTS: CSE had no significant cytotoxic effect in nasal fibroblast up to 5%. CSE significantly increased both VEGF mRNA and protein expression dose-dependently. The down-regulation of TLR4 transcription by siRNA treatment suppressed CSE-induced expressions of both TLR4 and VEGF. Pretreatment with ROS scavengers, specific inhibitors of each MAPK, and NF-kappaB inhibitor significantly decreased CSE-induced VEGF expression. CONCLUSIONS: CSE has a stimulatory effect on VEGF expression through the TLR4, ROS, MAPK, and NF-kappaB signaling pathway in nasal fibroblasts.

[Ab] Resumo:This study aimed to investigate the mechanism of hypoxia-inducible factor-1 alpha (HIF-1α) mediated hypoxia-induced permeability changes in bladder endothelial cells. Models of in vitro hypoxic cell culture of bladder cancer, bladder cancer cells with low HIF-1α expression and HIF-1α RNA interference (RNAi) expression vector were established. Western blot and reverse transcription polymerase chain reaction (RT-PCR) were used to detect the expression of HIF-1α and vascular endothelial growth factor (VEGF) in each group. Bladder cell permeability was determined. Results showed that protein and mRNA expression of HIF-1α and VEGF at 3 and 12 h of hypoxia were significantly higher than normal control (P<0.05), and peaked at 12 h. HIF-1α and VEGF expression in the hypoxic group and hypoxic+3-(5'-hydroxymethyl-2'-furyl)-1-benzyl indazole (YC-1) group were significantly higher than normal control (P<0.05), while expression in the hypoxic+YC-1 group was significantly lower than the hypoxic group (P<0.05). Bladder cell permeability in the hypoxic and hypoxic+YC-1 group were significantly increased compared to normal control (P<0.05), while in the hypoxic+YC-1 group was significantly decreased compared to the hypoxic group (P<0.05). Most of the cells in the stably transfected HIF-1α RNAi expression vector pcDNA6.2-GW/EmGFP-miR-siHIF-1α expressed green fluorescence protein (GFP) under fluorescence microscope. pcDNA6.2-GW/EmGFP-miR-siHIF-1α could significantly inhibit HIF-1α gene expression (P<0.05). HIF-1α and VEGF expression in the hypoxic group and siHIF-1α hypoxic group were significantly higher than normal group (P<0.05), while expression in the siHIF-1α hypoxic group was significantly lower than the hypoxic group (P<0.05). Findings suggest that HIF-1α is an important factor in the increase of bladder cancer cell permeability.

[Ab] Resumo:OBJECTIVES: To investigate the genetic polymorphism of SNP located in the 5' region of the vascular endothelial growth factor (VEGF) gene in Han population in Guangdong and provide basic data for forensic application and population genetics research. METHODS: The genetic polymorphisms of 4 SNP loci (rs699947, rs1570360, rs833061, rs2010963) within 5' region of VEGF gene of 184 unrelated individuals in Han population in Guangdong were analyzed by DNA micro sequencing technology SNaPshot. The statistical analysis was carried out by PowerMarker v3.25 software. RESULTS: The genotype distributions of the 4 SNP loci within 5' region of VEGF gene of 184 unrelated individuals in Han population in Guangdong were in accordance with Hardy-Weinberg equilibrium ( >0.05) and 3 kinds of genotypes were detected from each loci. There was high linkage disequilibrium between the rs833061 and rs699947 SNP loci. Six haplotypes were observed, while the frequency of C-G-T-C, C-G-T-G, A-A-C-G and A-G-C-G were more than 10%, which were the main haplotypes. The discrimination probabilities (DP) of rs699947, rs833061, and rs2010963 loci were between 0.583 and 0.634, with the power of exclusion (PE) between 0.133 and 0.144. The DP and PE of haplotypes of 4 SNP were 0.868 and 0.438, respectively. CONCLUSIONS: There are great polymorphisms in the 5' region of VEGF gene in Han population in Guangdong, which could be used as genetic indexes for individual identification and paternity testing, as well as association analysis of the related diseases.

[Ab] Resumo:POEMS syndrome is a rare paraneoplastic syndrome secondary to a plasma cell dyscrasia. Recognition of a combination of peripheral neuropathy, organomegaly, endocrinopathy, monoclonal plasmaproliferative disorder, skin changes, papilledema, extravascular volume overload, sclerotic bone lesions, thrombocytosis, and Castleman disease is the first step in managing the disease. Increased blood levels of vascular endothelial growth factor are usually confirmatory. This rare disorder should not be missed, especially if the patient has a putative diagnosis of chronic inflammatory polyradiculoneuropathy, a lambda restricted monoclonal gammopathy, and thrombocytosis, and is not responding as expected to immunomodulatory therapy commonly used for chronic inflammatory polyradiculoneuropathy.

[Ab] Resumo:PURPOSE: To evaluate the 12-month outcome of intravitreal anti-vascular endothelial growth factor therapy in eyes with bilateral retinal angiomatous proliferation (RAP). METHODS: This retrospective observational study included 38 eyes of 19 patients with stage 1 or 2 bilateral RAP at diagnosis. The eyes of patients who exhibited different baseline best-corrected visual acuity (BCVA) values in both eyes were assigned to one of two groups-the better (n=13) and worse (n=13) visual acuity groups. The BCVA values in both groups were compared to those at baseline and at 12 months. In addition, the 12-month changes in BCVA were compared between the two groups. The association between the optical coherence tomography findings at diagnosis and the 12-month BCVA was also analyzed. RESULTS: The values of mean baseline and 12-month BCVA in the better visual acuity group (13 eyes) were 0.48 ± 0.19 and 0.58 ± 0.29, respectively, and those in the worse visual acuity group (13 eyes) were 0.83 ± 0.20 and 0.90 ± 0.31. The 12-month changes in BCVA were not significantly different between the two groups (p=0.786). Among the six patients with equivalent baseline BCVA in both eyes, four patients (66.7%) exhibited 1 to 2 lines or ≥3 lines of difference in BCVA between eyes at 12 months. Eyes without pigment epithelial detachment (PED) at diagnosis exhibited significantly better BCVA at 12 months than eyes with PED (p=0.021). CONCLUSIONS: Better baseline visual acuity was associated with better BCVA at 12 months posttreatment in patients with bilateral RAP. However, equivalent baseline visual acuity in both eyes might not guarantee similar treatment outcomes. In addition, the absence of PED is predictive of better visual outcome.

[Ab] Resumo:An eye for an eye? Lack of consensus in off-label use of medications leads to major regional differences in medical costs for the treatment of wet AMD in Sweden. The three ocular VEGF inhibitors available in Sweden have similar efficacy and safety. Only two are however registered for wet AMD. The remaining, Avastin, is developed for oncological indications, but used for wet AMD in many parts of the world. Major regional differences exist in the use of Avastin in Sweden. In the three largest cities, it is not used at all. As a consequence, the yearly drug cost for a patient with wet AMD differs from 2 000 to 44 000 SEK. As this difference is not compatible with the Swedish law of "care on equal terms", increased efforts should be made to obtain a national consensus.

[Ab] Resumo:Umbilical cord blood (UCB) is a valuable graft source for allogeneic hematopoietic stem cell transplantation (HSCT) in patients who lack adult donors. UCB transplantation (UCBT) in adults results in delayed immune reconstitution, leading to high infection-related morbidity and mortality. Angiogenic factors and markers of endothelial dysfunction have biologic and prognostic significance in conventional HSCT, but their role in UCBT has not been investigated. Furthermore, the interplay between angiogenesis and immune reconstitution has not been studied. Here we examined whether angiogenic cytokines, angiopoietin-1 (ANG-1) and vascular endothelial growth factor (VEGF), or markers of endothelial injury, thrombomodulin (TM) and angiopoietin-2 (ANG-2), associate with thymic regeneration as determined by T cell receptor excision circle (TREC) values and recovery of T cell subsets, as well as clinical outcomes in adult recipients of UCBT. We found that plasma levels of ANG-1 significantly correlated with the reconstitution of naive CD4 CD45RA and CD8 CD45RA T cell subsets, whereas plasma levels of VEGF displayed a positive correlation with CD4 CD45RO T cells and regulatory T cells and a weak correlation with TRECs. Assessment of TM and ANG-2 revealed a strong inverse correlation of both factors with naive T cells and TRECs. The angiogenic capacity of each patient's plasma, as determined by an in vitro angiogenesis assay, positively correlated with VEGF levels and with reconstitution of CD4 T cell subsets. Higher VEGF levels were associated with worse progression-free survival and higher risk of relapse, whereas higher levels of TM were associated with chronic graft-versus-host disease and nonrelapse mortality. Thus, angiogenic factors may serve as valuable markers associated with T cell reconstitution and clinical outcomes after UCBT.
