Project description:Angiogenesis is an essential process in human physiology and disease pathology. Particularly, in ischemic disease condition, the proper induction of angiogenesis without vascular leakage will be crucial for its effective therapy. Ginsenosides, triterpenoid saponins from a well-known medicinal plant ginseng, have been considered as a strong candidate for modulating angiogenesis. However, the biologic activity of individual gensenoside compounds and their target pathway have not been elucidated systematically. To find the candidates of vascular-related therapeutic agents, we evaluated in vitro angiogenic efficacy of 10 ginsenosides using tube formation assay with human umbilical vein endothelial cells (HUVECs). Among them, F1 and Rh1 showed strong in vitro angiogenic properties including EC tube formation, proliferation, and migration similar to vascular endothelial growth factor (VEGF). However, RNA transcriptome analysis showed that F1 and Rh1 differentially regulate gene expressions in HUVECs compared to VEGF. Not only that, F1 and Rh1 significantly inhibited vascular endothelial growth factor (VEGF)-induced vascular leakage both in vitro and in vivo. From RNA transcriptome analysis, we identified that nuclear receptor subfamily 4 group A member 1 (NR4A1) is regulated by F1 and Rh1 for suppression of VEGF-induced vascular leakage. By suppressing the expression and transcriptional activity of NR4A1, F1 and Rh1 could stabilize the expression and localization of junctional vascular endothelial (VE)-cadherin. These findings demonstrate that F1 and Rh1 could be potential compounds in the development of vascular pharmaceuticals.

Project description:Vascular endothelial growth factor (VEGF) plays a key role in angiogenesis, but VEGF-induced angiogenesis is often accompanied by a vascular permeability response. Ginsenosides are triterpenoid saponins from the well-known medicinal plant, ginseng, and have been considered a candidate for modulating angiogenesis. Here, we systemically investigated the effects of 10 different ginsenosides on human umbilical vein endothelial cells and newly identified that two PPT-type ginsenosides, F1 and Rh1 induce the migration and proliferation of endothelial cells. Interestingly, RNA transcriptome analysis showed that gene regulation induced by VEGF in endothelial cells is distinct from that of ginsenoside F1 and Rh1. In addition, F1 and Rh1 significantly inhibited vascular leakage both in vitro and in vivo, which are induced by vascular endothelial growth factor. Furthermore, comparative transcriptome analysis revealed that these effects of F1 and Rh1 on vascular leakage restoration are mainly caused by changes in VEGF-mediated TNFα signaling via NFκB, particularly by the suppression of expression and transcriptional activity of NR4A1 by F1 and Rh1, even in the presence of VEGF. These findings demonstrate that ginsenosides F1 and Rh1 can be a promising herbal remedy for vessel normalization in ischemic disease and cancer and that NR4A1 is the key target.

Project description:Neovascular AMD (nAMD) causes vision loss from destructive angiogenesis, termed choroidal neovascularization (CNV). Cx3cr1-/- mice display non-classical monocyte and microglia alterations, and increased CNV size, suggesting that non-classical monocytes may inhibit CNV formation. While Nr4a1-/- mice are deficient in non-classical monocytes, results are confounded by macrophage hyper-activation. Nr4a1se2/se2 mice lack a transcriptional activator, resulting in non-classical monocyte loss, without macrophage hyper-activation. We subjected Nr4a1-/- and Nr4a1se2/se2 mice to the laser-induced CNV model and performed multi-parameter flow cytometry. We found that both models lack non-classical monocytes, but only Nr4a1-/- mice displayed increased CNV area. Additionally, CD11c+ macrophages were increased in Nr4a1-/- mice. Single-cell transcriptomic analysis uncovered that CD11c+ macrophages were enriched from Nr4a1-/- mice and expressed a pro-angiogenic transcriptomic profile that was disparate from prior reports of macrophage hyper-activation. These results suggest that non-classical monocytes are dispensable during laser-induced CNV, and NR4A1 deficiency shifts the transcriptional profile toward a pro-angiogenic phenotype.

Project description:Vascular permeability is frequently associated with inflammation and it is triggered by chemokines and by a cohort of secreted permeability factors, such as VEGF. In contrast, here we showed that the physiological vascular permeability that precedes implantation is directly controlled by progesterone receptor (PR) and it is independent of VEGF. Both global and endothelial-specific deletion of PR block physiological vascular permeability in the uterus while misexpression of PR in the endothelium of other organs results in ectopic vascular leakage. Integration of genome-wide transcriptional profile of endothelium and ChIP-sequencing revealed that PR induces a NR4A1 (Nur77/TR3) specific transcriptional program that broadly regulates vascular permeability in response to progesterone. This program triggers concurrent suppression of several junctional proteins and leads to an effective, timely and venule-specific regulation of vascular barrier function. Silencing NR4A1 blocks PR-mediated permeability responses indicating a direct link between PR and NR4A1. These results reveal a previously unknown function for progesterone receptor on endothelial cell biology with consequences to physiological vascular permeability and implications to the clinical use of progestins and anti-progestins on blood vessel integrity.

Project description:Background: Cantharidin, an active constituent of mylabris, is believed to have anti-tumor activity. Cantharidin selectively inhibit protein phosphatase 2A (PP2A), a repressor of oncogenic kinase pathways (ERK, JNK, NF-κB, and PKC). Cantharidin represses the growth and metastasis of pancreatic cancer cells in vitro. In the present study, we investigated the effects of cantharidin on pancreatic cancer xenografts in vivo. Methods: Cells stably expressing luciferase were used to establish xenograft models. Xenograft growth was evaluated by living imaging. Gene expression was determined using a microarray, real-time PCR, a RayBiotech antibody array, and the Milliplex assay. Results: Surprisingly, cantharidin significantly accelerated xenograft growth. Living imaging showed a rapid distribution of D-luciferin in cantharidin-treated xenografts, suggesting a rich blood supply. Immunohistochemistry confirmed increased angiogenesis. Microarray and antibody array identified upregulated pro-angiogenic and downregulated anti-angiogenic factors. The Milliplex assay suggested elevated secretion of IL-6, IL-8, TNF-α, and VEGF. ERK, JNK, NF-κB, and PKC pathway inhibitors attenuated the cantharidin-induced changes to pro-angiogenic gene expression. PKC pathway-inhibiting tamoxifen or antiangiogenic therapeutics, including Ginsenoside Rg3, bevacizumab, Apatinib, and Endostar antagonized the pro-angiogenic effect of cantharidin or its derivatives. These regimens presented remarkable synergistic antitumor effects in vivo. Conclusion: Although cantharidin presents anti-tumor effects in vitro and has been applied in clinical practice, we revealed an unfavorable pro-angiogenic side effect. We recommend that the clinical application of cantharidin should be performed on the premise of anti-vascularization therapy.
