Abstract
Chalcones and sulfonamides are well-known chemical groups associated with several biological activities such as antibiotic, anti-inflammatory, and antitumor activities. Over the past few decades, a series of sulfonamide-chalcone hybrids have been synthesized and assessed to develop compounds with interesting biological properties for application in disease therapy. In the present study, a new sulfonamide-chalcone hybrid μ - (2,5-dichloro-N-{4-[(3E)-4-(3-nitrophenyl) buta-1,3-dien-2-yl] phenyl} benzene sulfonamide), or simply CL185, was synthesized, and its angiogenic activity was assessed using the chick embryo chorioallantoic membrane (CAM) assay at different concentrations (12.5, 25, and 50 μg/μL). To further investigate the role of CL185 in the angiogenic process, we evaluated the levels of vascular endothelial growth factor (VEGF) in all treated CAMs. The results showed that all concentrations of CL185 significantly increased tissue vascularization (p < 0.05) as well as the parameters associated with angiogenesis, in which inflammation was the most marked phenomenon observed. In all CAMs treated with CL185, VEGF levels were significantly higher than those in the negative control (p < 0.05), and at the highest concentration, VEGF levels were even higher than in the positive control (p < 0.05). The pronounced angiogenic activity displayed by CL185 may be related to the increase in VEGF levels that were stimulated by inflammatory processes observed in our study. Therefore, CL185 presents a favorable profile for the development of drugs that can be used in pro-angiogenic and tissue repair therapies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Buxuhuayu decoction (BXHYD) has been frequently used to treat patients with diabetic ulcers (DUs), without notable adverse reactions. However, the related molecular mechanism remains unelucidated. AIM OF THE STUDY This study assessed the potential mechanism of BXHYD against DUs by using network pharmacology and animal experiments. MATERIALS AND METHODS First, high-performance liquid chromatography (HPLC) was used for quality control of BXHYD. Further, the hub compounds and targets were screened from the Active Compound-Targets (ACT) network and the protein and protein interaction (PPI) network. Enrichment analysis was performed using DAVID, and molecular docking technology was used to identify active compounds that may play a key role in pub targets. Finally, a DUs animal model was established and used to elucidate the effect of BXHYD on the PI3K/Akt/eNOS signalling pathway. RESULTS (1) Calycosin-7-glucoside, amygdalin, and tanshinone iiA were detected in the freeze-dried powder of BXHYD. (2) Twelve hub compounds and eight hub targets were screened using the ACT and PPI networks. Through molecular docking, it was found that the four hub targets (TP53, IL6, VEGFA, and AKT1) binds luteolin and quercetin more tightly. (3) BXHYD is most likely to promote angiogenesis and wound healing by activating the PI3K/Akt/eNOS signalling pathway. CONCLUSIONS This research revealed that BXHYD might activate the PI3K/Akt/eNOS signalling pathway to promote DUs healing. These findings support the clinical use of BXHYD and provide the foundation for its subsequent studies.

MicroRNA-101 inhibits cadmium-induced angiogenesis by targeting cyclooxygenase-2 in primary human umbilical vein endothelial cells. Biochem Pharmacol 2020; 189:114192.

Abstract
Exposure to toxic metal contaminants, such as cadmium compounds (Cd2+), has been shown to induce adverse effects on various organs and tissues. In particular, blood vessels are severely impacted by Cd2+ exposure, which may lead to cardiovascular diseases (CVDs). According to previous studies, CVDs are associated with increased cyclooxygenase 2 (COX-2) levels. However, the mechanisms by which CdCl2-induced COX-2 overexpression leads to cardiovascular dysfunction remain unclear. Herein, we show that the relative gene expressions of VEGF and PTGS2 (COX-2 encoding gene) are positively correlated in CVDs patients. Moreover, we demonstrate that the in vitro administration of CdCl2 induces cytotoxicity and endoplasmic reticulum (ER) stress in primary human umbilical vein endothelial cells (HUVECs). The induction of ER stress and the overexpression of COX-2 in CdCl2-treated cells alters the protein level of vascular endothelial growth factor (VEGF), resulting in abnormal angiogenesis and increased cytotoxicity. At the pre-transcription level, the inhibition of ER stress by siGRP78 (a key mediator of ER stress) can restore normal angiogenesis in the CdCl2-exposed cells. Meanwhile, at the transcription level, the adverse effects of CdCl2 exposure may be reversed via genetic modification with siRNA (siPTGS2) or by using phytochemical inhibitors (parthenolide, PN) of COX-2. Finally, at the post-transcription level, COX-2 expression may be restricted by the binding of microRNA-101 (miR-101) to the 3'-UTR of PTGS2 mRNA. The use of mimic miR-101 (mi101) to induce the expression of miR-101 eventually leads to reduced COX-2 protein levels, relieved ER stress, and less abnormal angiogenesis and cytotoxicity of CdCl2-exposed primary HUVECs. Overall, our results suggest that CdCl2-induced abnormal angiogenesis is mediated by miR-101/COX-2/VEGF-axis-dependent ER stress, and that cardiovascular dysfunction may be controlled by manipulating COX-2 at the pre-transcription, transcription, and post-transcription levels.

Abstract
Powder mixtures of tungsten carbide and metallic cobalt (WC-Co) are widely used in various products. Nanoparticles are engineered structures with at least one dimension of 100 nm or smaller. WC-Co is known to be associated with lung injury and diseases. Angiogenesis is a key process during vasculature, carcinogenesis, recovery of injury, and inflammatory diseases. However, the cellular effects of WC-Co nanoparticles on angiogenesis remain to be elucidated. In this study, we investigated angiogenic response and relative mechanisms after exposure to WC-Co nanoparticles. Our results showed that WC-Co nanoparticles at 5 μg/cm(2) induced ROS production which activated AKT and ERK1/2 signaling pathways in lung epithelial cells by reactive oxygen species (ROS) staining and immunoblotting; WC-Co treatment also increased transcriptional activation of AP-1, NF-κB, and VEGF by reporter assay. Further studies demonstrated that ROS are upstream molecules of AKT and ERK signaling pathways; the activation of AP-1, NF-κB, and VEGF was through ROS generation, AKT and ERK1/2 activation. In addition, WC-Co nanoparticles affected the cells to induce angiogenesis by chicken chorioallantoic membrane (CAM) assay. These results illustrate that exposure to WC-Co nanoparticles induces angiogenic response by activating ROS, AKT, and ERK1/2 signaling pathways and the downstream molecules and elucidate the potential molecular mechanisms during this process. This information may be useful for preventing potential damage from nanoparticle exposure in the future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diabetic foot ulceration results in high risk of lower extremity amputation, and represents a significant health care expenditure worldwide. Radix Astragali (RA) and Radix Rehmanniae (RR) are widely used Chinese medicinal herbs in treating diabetes, and have shown positive effects in enhancing wound healing in diabetic foot ulcer animal model. MATERIALS AND METHODS The angiogenic efficacy of NF3, a simplified 2-herb formula consisting of RA and RR in 2:1 ratio, was investigated. Median lethal concentration (LC50) and median effective concentration (EC50) were determined by treating zebrafish embryos with different concentrations of NF3 from 20 hpf to 72 hpf. The angiogenic activity of NF3 was examined in zebrafish embryos in vivo and by rat aortic ring assay in vitro. Cell cycle analysis of endothelial cells induced by NF3 was analyzed by flow cytometry using transgenic zebrafish Tg(fli1:EGFP). Real-time PCR was used to analyze mRNA expression profiles of selected genes involved in VEGF, FGF and MAPK pathways. RESULTS NF3 enhanced blood vessel formation as indicated by extra growth of intersegmental vessels in zebrafish embryos, and increased microvessels formation in rat aortic ring. NF3 also enhanced endothelial cells proliferation as shown by increased percentage of cells accumulating in S phase and G2/M phase of the cell cycle. NF3 exposure significantly induced up-regulation of VEGF-A, Flk-1, fgf1 and bRaf expression in zebrafish embryos. CONCLUSIONS Our results demonstrated that NF3 was effective in promoting angiogenesis in zebrafish embryos and by rat aortic ring assay, which provided scientific basis to support the use of NF3 as potential therapeutics in treating diabetic foot ulceration.

Abstract
This study was performed to evaluate the effects of nerve growth factor (NGF) upon angiogenesis in the rat cornea, to examine its possible application as an alternative angiogenic inducer and to provide basic data for further studies. Angiogenesis was induced by cornea micropocket assay, as previously described. Eight of thirty two eyes of Sprague-Dawley rats were randomly assigned to one of four groups, namely, a non-NGF group (Group 0), a 0.5 ng of NGF group (Group 0.5), a 1.0 ng of NGF group (Group 1.0) and a 5.0 ng of NGF group (Group 5.0). Pellets made of poly-2-hydroxylethylmethacrylate and sucralfate were implanted into the corneal stroma no closer than 1 mm from the limbus. After the implantation, the number of new vessels, vessel length and circumferential neovascularization were examined daily under the surgical microscope over a period of 7 days. The area of neovascularization was determined using a mathematical formula. Although new vessels in Group 0 and Group 0.5 were first observed at day 5, those of Groups 1.0 and 5.0 were first noted on days 4 and 3, respectively. However, the growth rates of new vessels in Groups 1.0 and 5.0 were higher than those of Groups 0 and 0.5 with the passage of time. The number, length, circumferential neovascularization and areas covered by the vessels in Groups 1.0 and 5.0 were significantly more than in Group 0 and Group 0.5 (p<0.05). This study showed that NGF had a dose-dependent angiogenic effects on the rat cornea and that the minimal effective dose of NGF was 1.0 ng per cornea. Also, it showed that NGF would be useful in angiogenic studies as an alternative angiogenic inducer.

Abstract
PURPOSE Angiostatin is a potent angiogenesis inhibitor that has been identified as a cryptic fragment of plasminogen molecule containing the first four kringle domain. Angiogenin, a 14-kDa monomeric protein, a potent blood vessel inducer, is expressed in tumors and present in mammalian plasma. The purpose of this study was to determine whether recombinant kringle 1-3 (rKI-3) of human plasminogen could interfere with angiogenesis induced by angiogenin and to evaluate the role of angiogenin in corneal angiogenesis in rabbit. METHODS A Hydron polymer pellet containing 2.0 microg of angiogenin was implanted intrastromally into the superior cornea of each of 44 rabbit eyes. All eyes received an intrastromal pellet and were randomized into either one group treated with 12.5 microg of rKI-3 (n = 25) or the other group treated with phosphate-buffered saline (PBS; n = 19). Both pellets were positioned in parallel at the site 1.2 mm from the superior limbus. Two masked observers kept the angiogenesis score daily, based on the number and the length of new vessels. The corneas with induced angiogenesis also were examined histologically. RESULTS On the third day of the angiogenin pellets implantation, the eye treated with rKI-3 had less angiogenesis (mean score, 4.2 +/- 6.6) than eye treated with PBS (mean score, 16.1 +/- 17.1; p < 0.05, Mann-Whitney U test). The cornea treated with PBS also showed much more leukocyte adhesion than the cornea treated with rKI-3. CONCLUSION Recombinant kringle 1-3 appears to inhibit angiogenin-induced angiogenesis in a rabbit corneal pocket assay. Recombinant kringle 1-3 may have therapeutic potential as an antiangiogenic agent.
