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.

Detection Of Biomarkers

The prevalence of comorbidities has been growing for the last decades. Therefore, the detection of biomarkers for diagnostic and prognostic purposes is of great practical importance. The aim of this study was to assess the biomarkers of osteo-defficiency in the course of secondary osteoporosis in patients with comorbid chronic pancreatitis and arterial hypertension. We examined 110 patients with chronic pancreatitis: 70 of them had comorbid hypertension, and 40 patients were found as having no comorbidities. The age of patients ranged from 33.2 ± 2.1 (main group) and 32.9 ± 3.1 years (comparison group); women predominated (72.9% and 70%, respectively). The control group includes 78 healthy individuals of the same age and sex. Diagnostic investigation included studying clinical and anamnestic characteristics of patients (duration of the disease, manifestations of the course, frequency of recrudescence, fractures) and biochemical parameters of bone metabolism: osteocalcin, total bone phosphatase and tartrate-resistant acid phosphatase and the establishment of correlations between these parameters and incidence of complications. It was found that in the isolated course of chronic pancreatitis there is a high (R = 0.60) statistically significant (p <0.01) correlation between the levels of osteocalcin and pancreatic elastase-1. A negative statistically significant (p <0.01) mean correlation (R = -0.49) was found between the content of tartrate-resistant acid phosphatase and age of the patients having comorbidity of chronic pancreatitis and hypertension, as well as there is a moderate correlation between the content of tartrate-resistant acid phosphatase and the duration of hypertension, which is statistically significant (R = 0.36, p <0.01). The levels of total bone phosphatase and tartrate-resistant acid phosphatase in the main group exceeded the reference values in 2.5 and 1.9 times respectively (CMU; U = 866.0; p <0.01), while in the comparison group were 2 times (total bone phosphatase) and 1.3 times higher (tartrate-resistant acid phosphatase) times, respectively (CMU; U = 821.0; p <0.01) that enables to diagnose the development of osteopenic conditions. That is, the combined course of chronic pancreatitis and hypertension should be considered as unfavourable tandem in the development of secondary osteoporosis and requires early osteoporotic screening.

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.

Polycystic ovary syndrome (PCOS) is a female endocrine disorder and frequently leads to infertility. Vascular endothelial growth factor (VEGF) has crucial roles and matrix metalloproteinase (MMPs) is correlated with cell migration. Both of them are involved in the occurrence and progression of PCOS. This study established a rat PCOS model using letrozole to measure the expression of VEGF, MMP-2 and MMP-9 (MMP-2/9), to analyze its correlation with PCOS. Letrozole was applied by gavage to establish rat PCOS model. General condition and ovarian tissue morphology were observed under a light field microscope. ELISA and immunohistochemistry (IHC) were used to detect serum or tissue expression of VEGF, MMP-2/9. Estrous cycle of rats was disrupted after 12 d for using letrozole. Vaginal smear showed abundant leukocytes with sparse keratinocytes. Ovary showed whitening and increased volume, with early phase small follicles plus lower granular cells or corpus luteum. Compared to control group, experimental group had significantly higher VEGF, MMP-2/9 (P < 0.05), which were higher in antral follicles than those in preantral follicle with higher expressions than primordial follicle (P < 0.05). In conclusion, VEGF, MMP-2/9 are abundantly expressed in both serum and tissues of PCOS rats.
