Background: Migraine has been considered a vascular risk factor especially in young women. Factors predisposing to endothelial damage in migraine are still being debated. The insufficiency of circulating endothelial precursor circulating cells (EPCs) suggested a link between migraine and cardiovascular risk. This research aimed to study a subtype of EPCs, those expressing e-selectin, to assess endothelial activation and, therefore, endothelial dysfunction in migraine. Methods: Consecutive headache patients ( n = 99) and 35 adjusted controls were recruited. Total EPCs, defined as CD34+/KDR+ cells, and EPC colony-forming units (CFUs) were assayed. We identified as “early” EPCs those CD62E– EPCs, and “late” EPCs, CD62E+, a surrogate marker for endothelial damage. Plasmatic calcitonin-gene related protein (CGRP) and vascular-endothelial growth factor (VEGF) were analyzed. Results: We did not find differences in the total number of CFUs among clinical groups. Means of total CD34+/KDR+ and “early” EPCs were not significant among clinical groups. Nevertheless, the mean of “late” EPCs was lower (log10-transformed mean = 1.715; SD = 0.393) in the control group than in the migraine patients (log10-transformed mean = 2.167; SD = 0.685), even after adjustment by VEGF plasma level and other confounding factors. Linear regression analyses disclosed significant predictors for “late” EPCs for controls vs migraine (β = 0.452 SE ± 0.13; p = 0.001). We did not observe differences between migraine with or without aura. Conclusion: We observed higher number of activated EPCs in migraine patients than in controls. CD62E+ EPCs might be considered a marker for vascular damage in migraine patients.

Abstract Background To quantify the expression of SP, CGRP, and VEGF in human dental pulps as a response to occlusal interferences, moderate orthodontic forces, and occlusal interferences plus moderate orthodontic forces simultaneously.Methods Forty human dental pulp samples were collected from healthy premolars indicated for extraction for orthodontic reasons. The teeth were divided into four groups with 10 samples each: Healthy pulp control group, occlusal interference group, moderate orthodontic forces group; and occlusal interferences plus moderate orthodontic forces group. Stimuli were applied for 24 h before tooth extraction in all experimental groups. All samples were processed, and SP, CGRP, and VEGF were measured by radioimmunoassay. The ANOVA test was performed to establish significant differences between groups and Tukey’s HSD post hoc comparisons were also performed.Results The highest increase in SP, CGRP, and VEGF expressions was found in the occlusal trauma plus orthodontic forces group, followed by the moderate orthodontic forces, the occlusal interferences and the control groups, with statistically significant differences between all groups (ANOVA p<0.001) and post-hoc comparisons (Tukey HSD p<0.001).Conclusion SP, CGRP, and VEGF expressions significantly increase in human dental pulps when stimulated by occlusal interferences combined with moderate orthodontic forces, as compared with when these two stimuli are applied independently. Peptides expression is directly proportional to the magnitude of the stimulus.Name of the registry: Importance of Neurogenic Inflammation in the Angiogenic Response of the Dental Pulp as a Defensive ResponseTrial registration number: NCT03804034Date of registration: 01/15/2019 Retrospectively registeredURL of trial registry record: https://clinicaltrials.gov/ct2/show/NCT03804034?term=NCT03804034&draw=2&rank=1

Retrograde menstruation lead to I Kappa B Kinase (IKK) fosforilation in peritoneum macrophage and cause secretion of proinflammatory cytokine interleukin1β then stimulate endometriosis cell to produce Vascular Endothelial Growth Factor which lead to increasing of endometriosis lession seen as endometriosis implant area. Cytokine secretion was inhibited through prevention of NF-κB activation by dragon red fruit rind extract (Hylocereuspolyrhizus). The aim of this reserach is to know the effect of dragon red fuit rind extract with 0,25; 0,5; and 1 mg/g bodyweight dosage toward IL-1β, VEGF expression and implant area in endometriosis mice model. The design of this experiment was randomized post test only control group design.Endometrios mice model were made in 14 days and split into two group, positive control group and treatment group after two week negative control group and postive control group were given Na-CMC 0,5% solution consequetively, and treatment group were given dragon red fruit extract with different dosage. Signification number for IL-1β is p>0,05, signification number for VEGF is p>0,05, and implant area signification number is p>0,05. Administration of dragon red fruit rind extract can decrease IL-1β, VEGF, and implant area.

Aims : The present study explored the clinical significance of microRNA-22 (miR-22) expression in lung squamous cell carcinoma and to explore the targeting relationship with vascular endothelial growth factor receptor 3 (VEGFR3). Methods: A total of 49 patients with lung squamous cell carcinoma who underwent surgical treatment was selected. The expression of miR-22 was detected by fluorescence quantitative real-time PCR (qPCR), the expression of VEGFR3 was detected by Western blotting assays, and D240 labeled microlymphatic vessels density (MLVD) was detected immunohistochemistry (IHC). Lung squamous cell carcinoma cell line SK-MES-1 was selected and the targeting relationship between miR-22 and VEGFR3 was analyzed by double luciferase reporter gene assay. Western blotting assays were used to detect the expression of vascular endothelial growth factor-D (VEGF-D) and D240 in the blank control group, empty vector transfection group, miR-22 transfection group, miR-22 and VEGFR3 co-transfection group. Results: The expression range of miR-22 in lung squamous cell carcinoma was 0.8-3.5. The expression of miR-22 in lung squamous cell carcinoma was significantly different by tumor maximum diameter, lymph node metastasis, vascular invasion and TNM stage. The expression of miR-22 was linked to survival time. There was a negative correlation between miR-22 and VEGFR3, miR-22 and MLVD. Double luciferase reporter gene assays showed that miR-22 reduced the luciferase activity of pGL3-VEGFR3-WT transfected cells. Compared with the control group, the expression of VEGF-D and D2-40 in the miR-22 transfection group was significantly decreased. However, VEGF-D and D240 in the miR-22 and VEGFR3 cotransfection group reversed the changes. Conclusion: We assumed that the abnormal expression of miR-22 in lung squamous cell carcinoma may be involved in the development and progression of lung squamous cell carcinoma. MiR-22 negatively regulated the target gene VEGFR3 to mediate lymphangiogenesis. The expression of miR-22 may also be linked to the prognosis of the disease.

Aim: The assessment of angiogenic parameters in so-called “liquid tumors”, such as myeloproliferative neoplasms, remains an open clinical issue. The aim of the study is to evaluate the concentration of vascular endothelial growth factor (VEGF-A) and soluble receptors sVEGFR-1 and sVEGFR-2 in relations to risk factors of thrombosis in patients with polycythemia vera (PV). Material/Methods: A total of 45 patients suffering from newly diagnosed PV and 30 healthy volunteers were enrolled into the study. Polycythemia vera was diagnosed according to the WHO (2008) criteria. In the citrated plasma samples VEGF-A, sVEGFR-1 and sVEGFR-2 were measured using ELISA tests. Results: VEGF-A concentration was three-fold higher and sVEGFR-2 significantly lower in PV patients as compared to the control group. VEGF-A concentration was significantly higher in PV patients with JAK2V617F mutation, as compared to patients without this mutation. SVEGFR-1 and sVEGFR-2 concentrations were similar in the analyzed subgroups. In PV patients with an increased number of white blood cells (WBCs), the above upper reference value (≥10 G/l), VEGF-A concentration was two-fold higher than in patients with WBCs number <10 G/l. However, sVEGFR-1 and sVEGFR-2 concentrations did not differ between the analyzed subgroups. Analysis of correlations revealed only one relation between VEGF-A and WBCs number. Conclusions: Increased VEGF-A and decreased sVEGFR-2 concentrations in polycythemia vera patients as compared to the control group indicate an intensification of the process of angiogenesis. A higher concentration of VEGF-A in PV patients with leukocytosis and a positive correlation between WBCs number and VEGF-A reflect the potential role of VEGF-A in the pathogenesis of thrombotic complications in hypercoagulable state in PV patients.

Anaerobic  exercise is a high-intensity exercise that needs quick energy supplies obtained in a very short time. However, this exercise may result in tissue hypoxia which is characterized by the increase of HIF-1α concentration. The presence of HIF-1α will induce the secretion of VEGF and, eventually, trigger angiogenesis. Nevertheless, it is still unclear whether anaerobic exercise will also cause hypoxia in which this condition will increase the concentration of VEGF in brain tissues. The aim of this study was to find out the effect of anaerobic exercise frequency towards VEGF concentration of Wistar rat brain tissues.  Brain tissues were taken from rats treated with anaerobic exercise using treadmill. This exercise was given in different frequencies; one time, three times, and seven times a week.  The data collected were analyzed using independent t-test. The results of this study showed that anaerobic  exercise done once a week could significantly increase VEGF concentration (p &lt; 0.05) if compared with the one in control group (95.21 ± 31.99 v.s. 63.36 ± 11.01 pg/mL). Meanwhile, VEGF concentration of treatment groups given exercise three times a week (47.97 ± 10.68 pg/mL) and seven times a week (40.56 ± 13.98 pg/mL) showed a significant decrease if compared with that of control group (63.36 ± 11.01 pg/mL). Anaerobic  exercise affected VEGF concentration as an indicator of angiogenesis in brain tissue of wistar rats.

Preeclampsia (PE) is characterized by a series of clinical features such as hypertension and proteinuria associated with endothelial dysfunction and the impairment of placenta vascular endothelial integrity. This study aimed to investigate the effect of serum copper (Cu) level on some angiogenesis-related factors including vascular endothelial growth factor-A (VEGF-A), soluble Fms-like tyrosine kinase-1 (sVEGF-R1), soluble endoglin (sEng) and cerruloplasmin (Cp) in Iraqi women with preeclampsia (PE) and control pregnant women. Therefore, 60 women with PE in addition to 30 healthy pregnant women were enrolled in the study. Serum concentration of sEng, VEGF-A, sVEGF-R1, and Cu in PE group significantly increased (p&lt;0.05) in the PE group compared with that in the control group. Increased production of antiangiogenic factors, soluble VEGF-A and sEng contribute to the pathophysiology of PE, indicating the involvement of these parameters in the angiogenic balance in patients with PE. Tests for between-subject effects showed that the circulating angiogenesis factors and Cu were significantly associated with the presence of PE. Serum Cu level was significantly correlated with VEGF- A and VEGF-R1 levels but not with sEng. Multiple regression analysis revealed that only Cp and BP can significantly predict the complications in women with PE. In conclusion, serum Cu has a role in the angiogenesis in women with PE and may be a new drug target in the prevention or treatment of PE.

Abstract The aim of the study was to determine the levels of the vascular endothelial growth factor (VEGF) in the serum of dogs suffering from splenic malignant tumours, prior to splenectomy, as well as three and six months after the surgery. Tumours and blood samples were collected from 10 dogs of various breeds, aged between 7 and 13 years, and from 10 control animals. Tumour sections were fixed in 10% buffered formalin for 24 h. The type of tumour was determined according to the WHO classification. Blood samples were centrifuged and the obtained sera were subjected to immunoenzymatic assays to determine the VEGF levels. The median of VEGF levels in the serum of dogs suffering from splenic malignant tumours was 37.85 pg/mL (15.40-107.18 pg/mL). The highest values were observed in dogs with confirmed metastases (107.18 pg/mL and 65.43 pg/mL). The VEGF values in control group were between 0.1 pg/mL and 13.04 pg/mL. A comparative analysis of the VEGF levels against the animals' survival time indicated that VEGF overexpression may serve as a prognostic factor in cases of malignant tumours of the spleen.
