Despite minoxidil and finasteride already being approved by the Food and Drug Administration (FDA) for the treatment of hair loss, it is important to identify new and innovative treatments for hair loss, such as looking for a solution in Chinese herbal medicine. One such treatment to consider is BeauTop (BT), whose primary ingredients include Panax japonicus (T.Nees), C.A. Mey. (Araliaceae), Astragalus membranaceus (Fisch) Bunge (Fabaceae), Angelica sinensis (Oliv.) Diels (Apiaceae), Ligustrum lucidum W.T. Aiton (Oleaceae), Rehmannia glutinosa (Gaertn.) DC. (Plantaginaceae), and Eclipta prostrata (L.) L. (Compositae). The aim of this study was to evaluate whether BT can promote hair growth in C57BL/6 mice and to investigate hair coverage, the expression of vascular endothelial growth factor (VEFG), and the numbers of hair follicles in growth phase after oral administration. A total of 12 C57BL/6 mice were divided into two groups: control group and treatment group BT. BT was administered orally as an extract at a volume of 0.6 g/kg. The control group was treated with distilled water. Each group was treated once a day for 12 consecutive days. To observe the expression of VEGF distribution, the number of hair follicles and the hair coverage were examined on days 4, 8, and 12. By comparing the treatment group and control group, we found that VEGF in the BT group on day 8 presented with a higher area percentage than the control group ( p value = 0.003). Hair follicle counting results showed that the BT group was significantly higher than the control group on day 8 ( p value = 0.031). Furthermore, hair coverage was shown to be significantly increased in the treatment group BT on day 8 ( p value = 0.013). Taken together, these results suggest that Chinese medicine (BT) possesses the potential effect of promoting hair growth through VEGF expression. VEGF is considered the most important mediator for the process of angiogenesis involved in hair growth development.

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.

Cytokine therapy has been suggested to improve left ventricle (LV) function after myocardial infarction (MI). The mechanisms for this benefit remain debatable. We investigated the impact of a prolonged combined therapy with Darbepoetin alfa (DARB) and Granulocyte Colony-Stimulating Factor (G-CSF) on LV function and vascular density after MI, correlating it with circulating progenitor cells (CPC), Vascular Endothelial Growth Factor (VEGF) and Stromal-Derived Factor 1 (SDF-1) release. Methods and Results : MI was induced in swine by a 90 minutes balloon occlusion of the left anterior descending artery. Animals were divided between treatment group with DARB-GCSF combination therapy (bolus of DARB 0.9 and GCSF 10ug/kg IV at time of reperfusion, followed by 5 doses of GCSF 5ug/kg SC from day 5 to 9, and four doses of 0.45ug/kg DARB SC once per week starting at day 1, n = 8) or control group (saline injections, n = 8). White blood cells (WBC), CPC, defined by CD45, CD31, CD90 and SLA-1 expression, and circulating levels of VEGF and SDF-1 were assessed at baseline (T0), 1 (T1), 2 (T2), and 3 (T3) weeks post-MI. LV function was assessed by echocardiography at T0, T1 and T6 (6 weeks post-MI), and vascular density by histology at T6. MI size was the same in both groups by post-MI CPK peak and LV ejection fraction (EF) at T1 (41+/−1 vs. 40+/−2%). In the treatment group only, from T0 to T1, there was an increase in WBC (16 ± 2 to 42 ± 2 x 10 6 /ml, p <0.01) and CPC (5 ± 1 to 9 ± 1 x 10 5 /ml, p = 0.01) and SDF-1 levels peaked from T0 to T2 (1345+/−60 to 1554 +/− 60 pg/ml; p<0.01) and stabilized at T3. All these values remained unchanged in the control group. VEGF levels (pg/ml) peaked at T2 in both groups (14+/−1 vs. 12+/−1), but remained increased at T3 in DARB-GCSF group only (13+/−1 vs. 9+/−1; p<0.01). LVEF (41+/−1 vs. 33+/−1, p<0.01) and arteriole density at the infarct zone (44+/−14 vs. 27+/−12/mm 2 , p = 0.02) and remote zone (18 +/−8 vs.11+/−5, p = 0.055) were higher compared to the control at T6. Conclusion : Our data suggest that prolonged therapy with DARB-GCSF combination after MI modulates angiogenesis and promotes stabilization of LV function by increasing CPC, and releasing SDF-1 and VEGF. This therapy provides a novel strategy to prevent post-MI LV remodeling and potentially improve outcome.

To investigate the effect of vascular endothelial growth factor (VEGF) on the early development and polyspermy rate of ovine embryos in vitro, 2 experiments were conducted with human recombinant VEGF165 supplemented to the media during maturation, fertilization, and culture in vitro, respectively. Ovaries were collected from ewes at a local slaughterhouse. All oocytes surrounded by a multilayer of cumulus cells were collected and rinsed 3 times in maturation medium (control medium and treatment medium, respectively). A total of 100 oocytes in each group were cultured in 4-well plates (Nunc) containing 800 μL of maturation medium at 38.5°C in an atmosphere of 5% CO2 with saturated humidity. Four replicates of each experiment were conducted. Statistical analyses were conducted by ANOVA with SPSS 12.0 software (SPSS Inc., Chicago, IL, USA). Data are expressed as means, and P < 0.05 was considered significant. In Experiment 1, to investigate the effect of VEGF on the early development of ovine embryos in vitro, VEGF was used at 5 ng mL–1 (treatment group A) and 10 ng mL–1 (treatment group B) in maturation medium (TCM-199 + BSA), HSOF fertilization medium, and SOF culture medium. The results showed that the maturation rate was increased significantly (P < 0.01), from 75.76% in the control treatment to 83.98 and 80.23% in treatment group A and treatment group B, respectively. The cleavage rate was increased from 75.85% in the control group to 79.39% in treatment group A (P > 0.05). The development rates of morulae (45.03%) and blastocysts (23.54%) in treatment group A were significantly higher (P < 0.01) than those in the control group (38.94 and 18.09%, respectively). In addition, the development rates of blastocysts in treatment group B (21.05%) were lower than those in treatment group A (P > 0.05) and higher than those in the control group (P > 0.05). In Experiment 2, to investigate the effect of VEGF on the polyspermy rate of ovine embryos in vitro, 5 ng mL–1 of VEGF was used in TCM-199 + BSA maturation medium in this experiment. The results showed that the fertilization rate after 18 h of IVF was increased significantly (P < 0.01), from 75.75% in the control group to 83.86% in the treatment group, and that the polyspermy rate was decreased significantly (P < 0.01), from 12.64% in the control group to 7.68% in the treatment group. These results indicate that VEGF significantly improved the maturation and fertilization rates of ovine oocytes and, consequently, the rate of embryo development in vitro, especially when the medium was supplemented with 5 ng mL–1 of VEGF. The VEGF obviously decreased the polyspermy rate and bated the phenomenon of polyspermy in the process of ovine oocyte IVF. The present study was supported by the National Natural Science Foundation of China (No. 30371035).

Objectives: Retinal vein occlusions (RVO) are associated with systemic risk factors. However, the ocular occlusive events might also influence a patient’s systemic condition. This study tried to investigate serum biomarkers associated with oxidative stress, before and after intravitreal anti-vascular endothelial growth factor (aVEGF) therapy in patients with RVOs. Methods: Newly-onset RVO patients were categorized into two groups: comorbid with macular edema requiring aVEGF therapy (treatment group) and no edema (observation group). Age and sex-matched patients (who received cataract surgery) were included as the control group. Intravitreal ranibizumab with a pro-re-nata regimen were administered. Serum samples were collected prior to treatment, at 6 and 12 months after therapy/observation and were collected once before controls who received cataract surgery. mRNA expression of sirtuin-1, its downstream genes, anti-oxidative biomarkers, and proinflammatory cytokines were measured. Results: There were 32, 26, and 34 patients enrolled in the treatment, observation, and control groups, respectively. The expressions of sirtuin-1 and its downstream genes were significantly lower in patients with RVO compared with the control group. Sirtuin-1 gene expression increased after 1 year of aVEGF therapy in the treatment group but remained unchanged in the observation group. Biomarkers of oxidative stress and proinflammatory cytokines were reduced after 1 year of aVEGF therapy. These biomarkers remained with no changes in the observation group. Conclusions: Our study showed that the systemic oxidative stress increased in RVO patients. The aVEGF therapy could alter the gene expression of anti-oxidative proteins and reduce systemic oxidative stress in these patients.

The present study aimed to estimate the efficiency of both a cellular bovine pericardium and bovine urinary bladder matrix sheets in the reconstruction of large ventro-lateral hernias in Iraqi bucks by using of molecular evaluation depending on real time-polymerase chain reaction technique to investigate the level of basic-fibroblast growth factor  and vascular endothelial growth factor  genes during the healing process and reconstruction of the abdominal defects. Under sedation and local anesthesia, (6cm X 8cm size) of ventro-lateral hernias were induced in 24 of Iraqi bucks. The animals were divided randomly into two main equal groups. In bovine pericardium-treatment group, the hernias were treated with onlay implantation of bovine pericardium. While, the hernias in UBM-treatment group were treated with onlay implantation of urinary bladder matrix, 30 days post-inducing of hernias. The molecular evaluation along the period of following-up recorded a significant up-regulation of the level of basic-fibroblast growth factor gene specific for presence of fibroblasts, myofibroblasts and collagen deposition in urinary bladder matrix -treatment group in comparison to bovine pericardium -treatment group with significant difference even at the end of the study. While, a significant up regulation of the levels of angiogenesis classic gene vascular endothelial growth factor  were recorded in the bucks of bovine pericardium -treatment group compared to urinary bladder matrix -treatment group. In conclusion; molecular detection of the level of growth factors in target tissue can be used as an important criterion.

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.

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.

We have previously shown that ultrasound-mediated (UM) delivery of vascular endothelial growth factor (VEGF) plasmid-bearing microbubbles promotes therapeutic angiogenesis. While VEGF is important during the initiation of angiogenesis, it results in primarily immature vessels, which are prone to late regression. Angiopoietin (Ang)-1 is a potent growth factor that acts to stabilize the neovasculature, later in the angiogenic process. We hypothesized that temporal delivery of VEGF and Ang-1 plasmid DNA would result in a more sustained angiogenic response, as compared to VEGF alone, in the setting of severe chronic ischemia. Methods : Unilateral hindlimb ischemia was produced by iliac artery ligation in 30 rats. At day 14 post-ligation, microvascular blood velocity (β) and flow (MBF) in the proximal hindlimb muscles were assessed by contrast-enhanced ultrasound (CEU). UM-delivery of plasmid (500 μg cDNA)-bearing microbubbles (1×109), was then performed at pre-specified time points, with treatment groups including VEGF alone at day 14; VEGF at day 14 followed by Ang-1 at day 28; and control rats receiving no therapy (n=10 per group). β and MBF were re-assessed at day 28 and 8 wks post-ligation. Results : Relative MBF (normalized to the contralateral normal leg) remained reduced at all time points after ligation in the control group. In VEGF-alone treated animals, MBF in the ischemic leg increased 2 wks after delivery (0.48 ± 0.19 to 0.82 ± 0.23, p < 0.001), but regressed over the next 4 wks (0.61 ± 0.14 at 8 wk, NS vs. 2 wks). In the VEGF/Ang-1 treated animals, MBF in the ischemic leg also increased 2 weeks after VEGF delivery (0.39 ± 0.19 to 0.69 ± 0.28, p < 0.01); however, vascular regression was prevented by late Ang1 delivery (0.83 ± 0.20 at 8 wks, p < 0.005 vs. 2 wks and p<0.01 vs VEGF alone at 8 wks). At week 8, relative β values were greater in VEGF/Ang-1 treated compared to VEGF-alone treated animals (0.87 ± 0.33 to 0.60 ± 0.23, p < 0.05). Conclusions : Compared to delivery of VEGF alone, delivery of Ang-1 plasmid DNA at 2 wks post-VEGF gene delivery results in sustained improvement in MBF, with prevention of late vascular regression. The greater microvascular blood velocity in VEGF/Ang-1 treated muscle may signify improved vascular functionality with late Ang-1 therapy.
