  • Optical clearing and fluorescence deep-tissue imaging for 3D quantitative
           analysis of the brain tumor microenvironment

      Abstract: Background Three-dimensional visualization of the brain vasculature and its interactions with surrounding cells may shed light on diseases where aberrant microvascular organization is involved, including glioblastoma (GBM). Intravital confocal imaging allows 3D visualization of microvascular structures and migration of cells in the brain of mice, however, with limited imaging depth. To enable comprehensive analysis of GBM and the brain microenvironment, in-depth 3D imaging methods are needed. Here, we employed methods for optical tissue clearing prior to 3D microscopy to visualize the brain microvasculature and routes of invasion of GBM cells. Methods We present a workflow for ex vivo imaging of optically cleared brain tumor tissues and subsequent computational modeling. This workflow was used for quantification of the microvasculature in relation to nuclear or cellular density in healthy mouse brain tissues and in human orthotopic, infiltrative GBM8 and E98 glioblastoma models. Results Ex vivo cleared mouse brain tissues had a >10-fold imaging depth as compared to intravital imaging of mouse brain in vivo. Imaging of optically cleared brain tissue allowed quantification of the 3D microvascular characteristics in healthy mouse brains and in tissues with diffuse, infiltrative growing GBM8 brain tumors. Detailed 3D visualization revealed the organization of tumor cells relative to the vasculature, in both gray matter and white matter regions, and patterns of multicellular GBM networks collectively invading the brain parenchyma. Conclusions Optical tissue clearing opens new avenues for combined quantitative and 3D microscopic analysis of the topographical relationship between GBM cells and their microenvironment.

  • Endothelium-derived fibronectin regulates neonatal vascular morphogenesis
           in an autocrine fashion
    • Authors: Christopher J. Turner; Kwabena Badu-Nkansah; Richard O. Hynes
      Abstract: Fibronectin containing alternatively spliced EIIIA and EIIIB domains is largely absent from mature quiescent vessels in adults, but is highly expressed around blood vessels during developmental and pathological angiogenesis. The precise functions of fibronectin and its splice variants during developmental angiogenesis however remain unclear due to the presence of cardiac, somitic, mesodermal and neural defects in existing global fibronectin KO mouse models. Using a rare family of surviving EIIIA EIIIB double KO mice, as well as inducible endothelial-specific fibronectin-deficient mutant mice, we show that vascular development in the neonatal retina is regulated in an autocrine manner by endothelium-derived fibronectin, and requires both EIIIA and EIIIB domains and the RGD-binding α5 and αv integrins for its function. Exogenous sources of fibronectin do not fully substitute for the autocrine function of endothelial fibronectin, demonstrating that fibronectins from different sources contribute differentially to specific aspects of angiogenesis.

  • Tumor angiogenesis and vascular normalization: alternative therapeutic
           targets
    • Authors: Claire Viallard; Bruno Larrivée
      Abstract: Tumor blood vessels are a key target for cancer therapeutic management. Tumor cells secrete high levels of pro-angiogenic factors which contribute to the creation of an abnormal vascular network characterized by disorganized, immature and permeable blood vessels, resulting in poorly perfused tumors. The hypoxic microenvironment created by impaired tumor perfusion can promote the selection of more invasive and aggressive tumor cells and can also impede the tumor-killing action of immune cells. Furthermore, abnormal tumor perfusion also reduces the diffusion of chemotherapeutic drugs and radiotherapy efficiency. To fight against this defective phenotype, the normalization of the tumor vasculature has emerged as a new therapeutic strategy. Vascular normalization, by restoring proper tumor perfusion and oxygenation, could limit tumor cell invasiveness and improve the effectiveness of anticancer treatments. In this review, we investigate the mechanisms involved in tumor angiogenesis and describe strategies used to achieve vascular normalization.

      Abstract: De novo synthesis of cytoskeleton-regulatory proteins triggered by the megakaryoblastic leukemia (MKL)/serum response factor (SRF) transcriptional system in response to pro-angiogenic growth factors lies at the heart of endothelial cell (EC) migration (a critical element of angiogenesis) and neovascularization. This study explores whether pharmacological intervention of MKL/SRF signaling axis by CCG-1423 is able to suppress angiogenesis. Our studies show that CCG-1423 inhibits migration and cord morphogenesis of EC in vitro and sprouting angiogenesis ex vivo and in vivo, suggesting CCG-1423 could be a novel anti-angiogenic agent. Kymography analyses of membrane dynamics of EC revealed that CCG-1423 treatment causes a major defect in membrane protrusion. CCG-1423 treatment led to attenuated expression of several actin-binding proteins that are important for driving membrane protrusion including ArpC2, VASP, and profilin1 (Pfn1) with the most drastic effect seen on the expression of Pfn1. Finally, depletion of Pfn1 alone is also sufficient for a dramatic decrease in sprouting angiogenesis of EC in vitro and ex vivo, further suggesting that Pfn1 depletion may be one of the mechanisms of the anti-angiogenic action of CCG-1423.

  • CXCL10 suppression of hem- and lymph-angiogenesis in inflamed corneas
           through MMP13
    • Authors: Nan Gao; Xiaowei Liu; Jiayin Wu; Juan Li; Chen Dong; Xinyi Wu; Xiao Xiao; Fu-Shin X. Yu
      Abstract: Though not present in the normal adult cornea, both hem- and lymph-angiogenesis can be induced in this tissue after an inflammatory, infectious, or traumatic insult. We previously showed that the chemokine CXCL10 plays a key role in eradicating invading Candida (C.) albicans in C57BL6 mouse corneas. However, even after the clearance of pathogens, infection-induced inflammation and angiogenesis continue to progress in the cornea. The aim of this study is define the role of CXCL10 as a major angiostatic factor in modulating cornea angiogenesis in B6 mouse corneas under pathogenic conditions. We showed that epithelial expression of CXCL10, driven by AAV9 vector, suppressed both infection- and inflammation-induced hem and lymph angiogenesis, whereas the neutralization of CXCL10 as well as its receptor CXCR3 greatly promoted these processes. The inhibitory effect of CXCL10 was unrelated to its antimicrobial activity, but through the suppression of the expression of many angiogenic factors, including VEGFa and c, and MMP-13 in vivo. Inhibition of MMP13 but not TIMPs, attenuated suture-induced neovascularization but had no effects on CXCL10 expression. Strikingly, topical application of CXCL10 post-C. albicans infection effectively blocked both hem- and lymph-angiogenesis and preserved the integrity of sensory nerves in the cornea. Taken together, CXCL10 has strong inhibitory effects on neovascularization, whereas MMP13 is required for neovascularization in C. albicans-infected corneas and the local application of CXCL10 or MMP13 inhibitors, alone or as adjuvant therapy, may target hem- and lymph-angiogenesis in the inflamed corneas.

  • Low levels of physiological interstitial flow eliminate morphogen
           gradients and guide angiogenesis
    • Authors: Venktesh S. Shirure; Andrew Lezia; Arnold Tao; Luis F. Alonzo; Steven C. George
      Abstract: Convective transport can significantly distort spatial concentration gradients. Interstitial flow is ubiquitous throughout living tissue, but our understanding of how interstitial flow affects concentration gradients in biological processes is limited. Interstitial flow is of particular interest for angiogenesis because pathological and physiological angiogenesis is associated with altered interstitial flow, and both interstitial flow and morphogen gradients (e.g., vascular endothelial growth factor, VEGF) can potentially stimulate and guide new blood vessel growth. We designed an in vitro microfluidic platform to simulate 3D angiogenesis in a tissue microenvironment that precisely controls interstitial flow and spatial morphogen gradients. The microvascular tissue was developed from endothelial colony forming cell-derived endothelial cells extracted from cord blood and stromal fibroblasts in a fibrin extracellular matrix. Pressure in the microfluidic lines was manipulated to control the interstitial flow. A mathematical model of mass and momentum transport, and experimental studies with fluorescently labeled dextran were performed to validate the platform. Our data demonstrate that at physiological interstitial flow (0.1–10 μm/s), morphogen gradients were eliminated within hours, and angiogenesis demonstrated a striking bias in the opposite direction of interstitial flow. The interstitial flow-directed angiogenesis was dependent on the presence of VEGF, and the effect was mediated by αvβ3 integrin. We conclude that under physiological conditions, growth factors such as VEGF and fluid forces work together to initiate and spatially guide angiogenesis.

  • miRNAs: micro-managers of anticancer combination therapies
    • Authors: Judy R. van Beijnum; Elisa Giovannetti; Dennis Poel; Patrycja Nowak-Sliwinska; Arjan W. Griffioen
      Abstract: Angiogenesis is one of the hallmarks of cancer progression and as such has been considered a target of therapeutic interest. However, single targeted agents have not fully lived up to the initial promise of anti-angiogenic therapy. Therefore, it has been suggested that combining therapies and agents will be the way forward in the oncology field. In recent years, microRNAs (miRNAs) have received considerable attention as drivers of tumor development and progression, either acting as tumor suppressors or as oncogenes (so-called oncomiRs), as well as in the process of tumor angiogenesis (angiomiRs). Not only from a functional, but also from a therapeutic view, miRNAs are attractive tools. Thus far, several mimics and antagonists of miRNAs have entered clinical development. Here, we review the provenance and promise of miRNAs as targets as well as therapeutics to contribute to anti-angiogenesis-based (combination) treatment of cancer.

  • Pathogenic role and therapeutic potential of pleiotrophin in mouse models
           of ocular vascular disease
    • Authors: Weiwen Wang; Michelle E. LeBlanc; Xiuping Chen; Ping Chen; Yanli Ji; Megan Brewer; Hong Tian; Samantha R. Spring; Keith A. Webster; Wei Li
      Abstract: Angiogenic factors play an important role in the pathogenesis of diabetic retinopathy (DR), neovascular age-related macular degeneration (nAMD) and retinopathy of prematurity (ROP). Pleiotrophin, a well-known angiogenic factor, was recently reported to be upregulated in the vitreous fluid of patients with proliferative DR (PDR). However, its pathogenic role and therapeutic potential in ocular vascular diseases have not been defined in vivo. Here using corneal pocket assays, we demonstrated that pleiotrophin induced angiogenesis in vivo. To investigate the pathological role of pleiotrophin we used neutralizing antibody to block its function in multiple in vivo models of ocular vascular diseases. In a mouse model of DR, intravitreal injection of pleiotrophin-neutralizing antibody alleviated diabetic retinal vascular leakage. In a mouse model of oxygen-induced retinopathy (OIR), which is a surrogate model of ROP and PDR, we demonstrated that intravitreal injection of anti-pleiotrophin antibody prevented OIR-induced pathological retinal neovascularization and aberrant vessel tufts. Finally, pleiotrophin-neutralizing antibody ameliorated laser-induced choroidal neovascularization, a mouse model of nAMD, suggesting that pleiotrophin is involved in choroidal vascular disease. These findings suggest that pleiotrophin plays an important role in the pathogenesis of DR with retinal vascular leakage, ROP with retinal neovascularization and nAMD with choroidal neovascularization. The results also support pleiotrophin as a promising target for anti-angiogenic therapy.

  • Antiangiogenic therapy combined with immune checkpoint blockade in renal
           cancer
    • Authors: Teele Kuusk; Laurence Albiges; Bernard Escudier; Nikolaos Grivas; John Haanen; Thomas Powles; Axel Bex
      Abstract: Antiangiogenic therapy with vascular endothelial growth factor (VEGF) inhibitors is the current first-line treatment in metastatic renal cell carcinoma (mRCC). Immunotherapy with checkpoint inhibitor has been recently added to the armamentarium of mRCC treatment. These therapies are based on treatment with antibodies that block programmed cell death-1 (PD-1), programmed cell death ligand 1 (PD-L1) pathways, demonstrating impressive response rates and improved survival in several tumour types. So far, nivolumab is the only approved anti-PD-1 monoclonal antibody after VEGF therapy in mRCC. According to preclinical and clinical studies, combination therapies with VEGF- and checkpoint inhibitors have synergistic effect achieving improved response rates. However, toxicity in some combinations is high. In this article, we present a review of the ongoing trials with these drug combinations for RCC.

  • A novel strategy to enhance angiogenesis in vivo using the small
           VEGF-binding peptide PR1P
    • Authors: Avner Adini; Irit Adini; Zai-long Chi; Ratmir Derda; Amy E. Birsner; Benjamin D. Matthews; Robert J. D’Amato
      Abstract: Therapeutic angiogenesis is an experimental frontier in vascular biology that seeks to deliver angiogenic growth factors to ischemic or injured tissues to promote targeted formation of new blood vessels as an alternative approach to surgical revascularization procedures. Vascular endothelial growth factor (VEGF) is a potent angiogenic signal protein that is locally upregulated at sites of tissue injury. However, therapies aimed at increasing VEGF levels experimentally by injecting VEGF gene or protein failed to improve outcomes in human trials in part due to its short half-life and systemic toxicity. We recently designed a novel 12-amino acid peptide (PR1P) whose sequence was derived from an extracellular VEGF-binding domain of the pro-angiogenic glycoprotein prominin-1. In this study, we characterized the molecular binding properties of this novel potential therapeutic for targeted angiogenesis and provided the foundation for its use as an angiogenic molecule that can potentiate endogenous VEGF. We showed that PR1P bound VEGF directly and enhanced VEGF binding to endothelial cells and to VEGF receptors VEGFR2 and neuropilin-1. PR1P increased angiogenesis in the murine corneal micropocket assay when combined with VEGF, but had no activity without added VEGF. In addition, PR1P also enhanced angiogenesis in murine choroidal neovascularization and wound-healing models and augmented reperfusion in a murine hind-limb ischemia model. Together our data suggest that PR1P enhanced angiogenesis by potentiating the activity of endogenous VEGF. In so doing, this novel therapy takes advantage of endogenous VEGF gradients generated in injured tissues and may improve the efficacy of and avoid systemic toxicity seen with previous VEGF therapies.

  • Pro-angiogenic capacities of microvesicles produced by skin wound
           myofibroblasts
    • Authors: Mays Merjaneh; Amélie Langlois; Sébastien Larochelle; Chanel Beaudoin Cloutier; Sylvie Ricard-Blum; Véronique J. Moulin
      Abstract: Wound healing is a very highly organized process where numerous cell types are tightly regulated to restore injured tissue. Myofibroblasts are cells that produce new extracellular matrix and contract wound edges. We previously reported that the human myofibroblasts isolated from normal wound (WMyos) produced microvesicles (MVs) in the presence of the serum. In this study, MVs were further characterized using a proteomic strategy and potential functions of the MVs were determined. MV proteins isolated from six WMyo populations were separated using two-dimensional differential gel electrophoresis. Highly conserved spots were selected and analyzed using mass spectrometry resulting in the identification of 381 different human proteins. Using the DAVID database, clusters of proteins involved in cell motion, apoptosis and adhesion, but also in extracellular matrix production (21 proteins, enrichment score: 3.32) and in blood vessel development/angiogenesis (19 proteins, enrichment score: 2.66) were identified. Another analysis using the functional enrichment analysis tool FunRich was consistent with these results. While the action of the myofibroblasts on extracellular matrix formation is well known, their angiogenic potential is less studied. To further characterize the angiogenic activity of the MVs, they were added to cultured microvascular endothelial cells to evaluate their influence on cell growth and migration using scratch test and capillary-like structure formation in Matrigel®. The addition of a MV-enriched preparation significantly increased endothelial cell growth, migration and capillary formation compared with controls. The release of microvesicles by the wound myofibroblasts brings new perspectives to the field of communication between cells during the normal healing process.

  • Contribution of tumor endothelial cells to drug resistance:
           anti-angiogenic tyrosine kinase inhibitors act as p-glycoprotein
           antagonists
    • Authors: MariaRosa Bani; Alessandra Decio; Raffaella Giavazzi; Carmen Ghilardi
      Abstract: Tumor endothelial cells (TEC) differ from the normal counterpart, in both gene expression and functionality. TEC may acquire drug resistance, a characteristic that is maintained in vitro. There is evidence that TEC are more resistant to chemotherapeutic drugs, substrates of ATP-binding cassette (ABC) transporters. TEC express p-glycoprotein (encoded by ABCB1), while no difference in other ABC transporters was revealed compared to normal endothelia. A class of tyrosine kinase inhibitors (TKI), used as angiostatic compounds, interferes with the ATPase activity of p-glycoprotein, thus impairing its functionality. The exposure of ovarian adenocarcinoma TEC to the TKIs sunitinib or sorafenib was found to abrogate resistance (proliferation and motility) to doxorubicin and paclitaxel in vitro, increasing intracellular drug accumulation. A similar effect has been reported by the p-glycoprotein inhibitor verapamil. No beneficial effect was observed in combination with cytotoxic drugs that are not p-glycoprotein substrates. The current paper reviews the mechanisms of TEC chemoresistance and shows the role of p-glycoprotein in mediating such resistance. Inhibition of p-glycoprotein by anti-angiogenic TKI might contribute to the beneficial effect of these small molecules, when combined with chemotherapy, in counteracting acquired drug resistance.

      Abstract: Cancer cells are often dependent on epigenetic pathways for their survival. Consequently, drugs that target the epigenome, rather than the underlying DNA sequence, are currently attracting considerable attention. In recent years, the first epigenetic drugs have been approved for cancer chemotherapy, mainly for hematological applications. Limitations in single-drug efficacies have thus far limited their application in the treatment of solid tumors. Nevertheless, promising activity for these compounds has been suggested when combined with other, distinctly targeted agents. In this review, we discuss the anti-angiogenic activity of histone deacetylase and DNA methyltransferase inhibitors and their combinations with other targeted (anti-angiogenic) therapeutics in treatment of solid tumors. The role that these inhibitors play in the inhibition of tumor angiogenesis, particularly in combination with other targeted agents, and the advantages they present over broad acting anticancer agents, are critically discussed.

  • Blood flow can signal during angiogenesis not only through
           mechanotransduction, but also by affecting growth factor distribution
    • Authors: Siavash Ghaffari; Richard L. Leask; Elizabeth A. V. Jones
      Abstract: Growth factors, such as VEGF, promote the sprouting of new blood vessels. Growth factors are generally produced far from the endothelium, and the transport of these proteins is often assumed to occur through diffusion. When sprouting occurs in a perfused vascular bed, however, interstitial flow is present that can modify protein transport. We recently developed a technique to analyze flow dynamics and vascular remodeling simultaneously in avian embryos. In this study, we extend our technique to model interstitial flow through the porous matrix of the mesenchymal tissue and use this to investigate how flow in the blood vessels affects the distribution of growth factors in the mesenchyme, using VEGF as a prototypical angiogenic molecule. We find that flow controls sprouting location and elongation, both through the direct action of mechanical force and through indirect effects on growth factor distribution. Most importantly, we find that the distribution of VEGF is regulated by interstitial flow, and the effect of diffusion of VEGF is negligible.

  • The clinical application of angiostatic therapy in combination with
           radiotherapy: past, present, future
    • Authors: Lisanne C. Hamming; Ben J. Slotman; Henk M. W. Verheul; Victor L. Thijssen
      Abstract: Although monotherapy with angiostatic drugs is still far from effective, there is abundant evidence that angiostatic therapy can improve the efficacy of conventional treatments like radiotherapy. This has instigated numerous efforts to optimize and clinically implement the combination of angiostatic drugs with radiation treatment. The results from past and present clinical trials that explored this combination therapy indeed show encouraging results. However, current findings also show that the combination has variable efficacy and is associated with increased toxicity. This indicates that combining radiotherapy with angiostatic drugs not only holds opportunities but also provides several challenges. In the current review, we provide an update of the most recent insights from clinical trials that evaluated the combination of angiostatic drugs with radiation treatment. In addition, we discuss the outstanding questions for future studies in order to improve the clinical benefit of combining angiostatic therapy with radiation therapy.

  • Anti-angiogenesis for cancer revisited: Is there a role for combinations
           with immunotherapy'
    • Authors: Rakesh R. Ramjiawan; Arjan W. Griffioen; Dan G. Duda
      Abstract: Angiogenesis is defined as the formation of new blood vessels from preexisting vessels and has been characterized as an essential process for tumor cell proliferation and viability. This has led to the development of pharmacological agents for anti-angiogenesis to disrupt the vascular supply and starve tumor of nutrients and oxygen, primarily through blockade of VEGF/VEGFR signaling. This effort has resulted in 11 anti-VEGF drugs approved for certain advanced cancers, alone or in combination with chemotherapy or other targeted therapies. But this success had only limited impact on overall survival of cancer patients and rarely resulted in durable responses. Given the recent success of immunotherapies, combinations of anti-angiogenics with immune checkpoint blockers have become an attractive strategy. However, implementing such combinations will require a better mechanistic understanding of their interaction. Due to overexpression of pro-angiogenic factors in tumors, their vasculature is often tortuous and disorganized, with excessively branched leaky vessels. This enhances vascular permeability, which in turn is associated with high interstitial fluid pressure, and a reduction in blood perfusion and oxygenation. Judicious dosing of anti-angiogenic treatment can transiently normalize the tumor vasculature by decreasing vascular permeability and improving tumor perfusion and blood flow, and synergize with immunotherapy in this time window. However, anti-angiogenics may also excessively prune tumor vessels in a dose and time-dependent manner, which induces hypoxia and immunosuppression, including increased expression of the immune checkpoint programmed death receptor ligand (PD-L1). This review focuses on revisiting the concept of anti-angiogenesis in combination with immunotherapy as a strategy for cancer treatment.

      Abstract: Nintedanib, a tyrosine kinase inhibitor approved for the treatment of idiopathic pulmonary fibrosis, has anti-fibrotic, anti-inflammatory, and anti-angiogenic activity. We explored the impact of nintedanib on microvascular architecture in a pulmonary fibrosis model. Lung fibrosis was induced in C57Bl/6 mice by intratracheal bleomycin (0.5 mg/kg). Nintedanib was started after the onset of lung pathology (50 mg/kg twice daily, orally). Micro-computed tomography was performed via volumetric assessment. Static lung compliance and forced vital capacity were determined by invasive measurements. Mice were subjected to bronchoalveolar lavage and histologic analyses, or perfused with a casting resin. Microvascular corrosion casts were imaged by scanning electron microscopy and synchrotron radiation tomographic microscopy, and quantified morphometrically. Bleomycin administration resulted in a significant increase in higher-density areas in the lungs detected by micro-computed tomography, which was significantly attenuated by nintedanib. Nintedanib significantly reduced lung fibrosis and vascular proliferation, normalized the distorted microvascular architecture, and was associated with a trend toward improvement in lung function and inflammation. Nintedanib resulted in a prominent improvement in pulmonary microvascular architecture, which outperformed the effect of nintedanib on lung function and inflammation. These findings uncover a potential new mode of action of nintedanib that may contribute to its efficacy in idiopathic pulmonary fibrosis.
