Abstract Background The present study aims to determine the predictive value of vascular endothelial growth factor (VEGF) and placenta growth factor (PLGF) for placenta accreta and for the comparison of the serum level of VEGF and PLGF in normal pregnant women and women with placenta accreta spectrum (PAS).Methods This prospective case-control study was conducted during the 2 years in two hospital in Shiraz, Iran from 2017 to 2019. The inclusion of the study was 90 singleton pregnant women: 45 of them in gestational ages of 28-34 weeks with pathological confirmation of placenta accreta spectrum and 45 healthy pregnant women. In the PAS group, according to pathology reports on the placenta, we divided all cases to placenta accreta, percreta, and increta. Maternal serum level of VEGF and PLGF were measured before the termination of pregnancy and diagnostic accuracy of each factor was evaluated.Results In PAS group, 75 percent of patients had placenta previa and unlike the control group, there was a significant difference in the gravidity, number of cesarean section, maternal age, and serum level of PLGF (p< /001); while in VEGF, the difference was not statistically significant.Conclusions The results of the present study revealed that the maternal serum level of PLGF could be considered as an accurate predictive test in patients with PAS.

The aim of our study was to examine the involvement of renin-angiotensin system (RAS) in estrogen-induced lactotropes proliferation and vascular endothelial growth factor (VEGF) expression in rat pituitary. The study was performed on Fisher 344 rats underwent 8-day treatment with diethylstilboestrol (DES). The proliferation index (PCNA) and VEGF expression in pituitary sections were estimated using immunohistochemical methods. Treatment with DES increased the number of PCNA-positive cells, VEGF-positive cells, and VEGF-positive blood vessels in pituitary. Stimulatory effect of estrogen on cell proliferation and VEGF expression in blood vessels was attenuated by losartan, PD123319, and captopril. VEGF immunoreactivity in pituitary cells of DES-treated rats was decreased by AT1 antagonist and not changed by AT2 blocker and ACE inhibitor. Our findings suggest the involvement of RAS in DES-induced cell proliferation and VEGF expression in pituitary. Both the AT1 and AT2 receptors appear to mediate the estrogen-dependent mitogenic and proangiogenic effects in rat pituitary.

The Impact

Introduction. Increased angiogenesis in bone marrow is one of the characteristics of chronic myeloid leukaemia (CML), a clonal myeloproliferative disorder that expresses a chimeric bcr/abl protein. Vascular endothelial growth factor (VEGF) is one of the most potent and a specific regulator of angiogenesis which principally targets endothelial cells and regulates several of their functions, including mitogenesis, permeability and migration. The impact of elevated VEGF expression on the course of chronic myeloid leukaemia is unknown. Objective. The aim of this study was the follow-up of VEGF expression during the course of CML. Methods. We studied VEGF expression of 85 CML patients (median age 50 years, range 16-75 years). At the commencement of the study, 29 patients were in chronic phase (CP), 25 in an accelerated phase (AP), and 31 in the blast crisis (BC). The temporal expression (percentage positivity per 1000 analysed cells) VEGF proteins over the course of CML were studied using the immunohistochemical technique utilizing relevant monoclonal antibodies. It was correlated with the laboratory (Hb, WBC and platelet counts, and the percentage of blasts) and clinical parameters (organomegaly, duration of CP, AP, and BC) of disease progression. Results. The expression of VEGF protein was most pronounced in AP (ANOVA, p=0.033). The level of VEGF expression correlated inversely with the degree of splenomegaly (Pearson, r=-0.400, p=0.011). High expression of VEGF correlated with a shorter overall survival (log rank, p=0.042). Conclusion. Immunohistochemically confirmed significance of the expression of VEGF in dependence of the CML stage could be of clinical importance in deciding on the timing therapy. These data suggest that VEGF plays a role in the biology of CML and that VEGF inhibitors should be investigated in CML.

Adaptation To Exercise

We have previously shown, using a Cre-LoxP strategy, that vascular endothelial growth factor (VEGF) is required for the development and maintenance of skeletal muscle capillarity in sedentary adult mice. To determine whether VEGF expression is required for skeletal muscle capillary adaptation to exercise training, gastrocnemius muscle capillarity was measured in myocyte-specific VEGF gene-deleted (mVEGF−/−) and wild-type (WT) littermate mice following 6 wk of treadmill running (1 h/day, 5 days/wk) at the same running speed. The effect of training on metabolic enzyme activity levels and whole body running performance was also evaluated in mVEGF−/− and WT mice. Posttraining capillary density was significantly increased by 59% ( P < 0.05) in the deep muscle region of the gastrocnemius in WT mice but did not change in mVEGF−/− mice. Maximal running speed and time to exhaustion during submaximal running increased by 20 and 13% ( P < 0.05), respectively, in WT mice after training but were unchanged in mVEGF−/− mice. Training led to increases in skeletal muscle citrate synthase (CS) and phosphofructokinase (PFK) activities in both WT and mVEGF−/− mice ( P < 0.05), whereas β-hydroxyacyl-CoA dehydrogenase (β-HAD) activity was increased only in WT mice. These data demonstrate that skeletal muscle capillary adaptation to physical training does not occur in the absence of myocyte-expressed VEGF. However, skeletal muscle metabolic adaptation to exercise training takes place independent of myocyte VEGF expression.
