Malignant glioma, the most common intracranial primary tumor, is characterized by increased angiogenesis. Accumulating evidence has shown that long non-coding RNAs (lncRNAs) play an important role in a variety of biological behaviors of tumors. However, the role of lncRNAs in the regulation of glioma vascular endothelial cell function remains to be investigated. To simulate the glioma microenvironment, we applied glioma conditioned medium (GCM) to human cerebral microvascular endothelial cells (hCMECs). In the present study, the lncRNA SNHG15 was found to be highly expressed in glioma vascular endothelial cells...

Previous studies have shown that cysteine-rich buccal gland protein (CRBGP) from buccal glands of Lampetra japonica could suppress angiogenesis in chorioallantoic membrane models. As CRBGP is composed of a pathogenesis-related group 1 (PR-1) domain and a cysteine-rich domain (CRD), which domain accounts for the effects of CRBGP on anti-angiogenesis? In the present study, recombinant PR-1 and CRD (rL-PR-1 and rL-CRD) were obtained. MTT assay showed rL-PR-1 inhibited the proliferation of HUVECs significantly in a dose-dependent manner with an IC50 of 2μM, while rL-CRD had no obviously inhibitory effect on the proliferation of HUVECs, suggested that PR-1 is the main function domain on the anti-angiogenic activity of CRBGP...

VEGFR-2, TIE-2, and EphB4 are essential for both angiogenesis and tumorigenesis. Herein, we designed and prepared three classes of multi-target inhibitors based on the extensive sequence homology along the kinase domain of angiogenic RTKs. Biological evaluation indicated that these multi-target inhibitors exhibited considerable potential as novel anti-angiogeneic and anticancer agents. Among them, a diaryl thiourea bearing 1H-indazole-3-amine (16a) displayed the most potent RTK inhibition and excellent selectivity...

Angiogenesis is a dynamic, multi-step process. It is known that about 70 diseases are related to angiogenesis. Both the experimental and the literature reports showed that Sophora flavescens inhibit angiogenesis significantly, but the material basis and the mechanism of action have not been clear. In this study, molecular docking was used for screening of anti-angiogenesis flavonoids from the roots of S. flavescens. One handred and twenty-six flavonoids selected from S. flavescens were screened in the docking ligand database with six targets(VEGF-a,TEK,KDR,Flt1,FGFR1 and FGFR2) as the receptors...

Anti-angiogenesis effect of a prodrug of green tea polyphenol (-)-epigallocatechin-3-gallate (Pro-EGCG) in malignant tumors is not well studied. Here, we investigated how the treatment with Pro-EGCG inhibited tumor angiogenesis in endometrial cancer. Tumor xenografts of human endometrial cancer were established and subjected to microarray analysis after Pro-EGCG treatment. First, we showed Pro-EGCG inhibited tumor angiogenesis in xenograft models through down-regulation of vascular endothelial growth factor A (VEGFA) and hypoxia inducible factor 1 alpha (HIF1α) in tumor cells and chemokine (C-X-C motif) ligand 12 (CXCL12) in host stroma by immunohistochemical staining...

Age-related macular degeneration (AMD), in which choroidal neovascularization (CNV) affects the center of the retina (macula), leads to the irreversible visual loss. The intravitreal injection of anti-angiogenesis antibodies improved the prognosis of AMD, but relatively less invasive therapies should be explored. In the present study, we show that a high-density lipoprotein (HDL) mutant is a therapeutically active drug carrier capable of treating a posterior eye disease in mice via instillation. Various HDL mutants were prepared with apoA-I proteins fused with different cell-penetrating peptides (CPPs) and phospholipids with different alkyl chain lengths; their sizes were further controlled in the range of 10-25nm...

Melatonin, a pineal indolamine, participates in different body functions and is shown to possess diverse biological activities such as anti-tumor action. Angiogenesis inhibition is one of the mechanisms by which melatonin exerts its oncostatic effects. Increased angiogenesis is a major feature of tumor progression, thus angiogenesis inhibition is a critical step in cancer therapy. Melatonin employs a variety of mechanisms to target nutrients and oxygen supply to cancer cells. At the transcriptional level, hypoxia induced factor-1α (HIF-1α) and the genes under its control, such as vascular endothelial growth factor (VEGF) are the main targets of melatonin for inhibition of angiogenesis...

Tumor microenvironment has a crucial role in cancer development and progression, whereas the mechanism of how it regulates angiogenesis is unclear. In this study, we simulated the colorectal carcinoma microenvironment by conditioned medium (CM) of colorectal carcinoma cell lines (SW620, HT-29, HCT116) supernatant or colorectal carcinoma tissue homogenate supernatant to induce normal endothelial cells (NECs). We found that colorectal carcinoma CM promoted tumor angiogenesis by coercing NECs toward tumor endothelial cells (TECs) with the activation of the JAK/STAT3 signaling pathway...

Osteopontin (OPN) is an extracellular structural protein that is secreted by osteoblasts and hematopoietic cells. It suppresses the proliferation of hematopoietic stem and also plays an important role in promoting survival and drug resistance in leukemic stem cells (LSCs). Since the role of OPN isoforms in AML angiogenesis are remaining controversial, in the present study, we aimed to evaluate whether curcumin (CUR), as a known natural component with anti-angiogenesis effects, in a combination of AML conventional regiment has the potency to preclude induced anti-angiogenesis effects of OPN isoforms or not? Leukemia cells were treated with different concentration of CUR and AML conventional drugs alone and/or in combination with together to find effective doses and IC50 values...
