Abstract
Angiogenesis and vasculogenic mimicry (VM) are the main causes of tumor metastasis and recurrence. In this study, we investigated the antiangiogenesis and anti-VM formation of a novel microtubule depolymerizing agent, DHPAC, as well as combretastatin A4 (CA4, a combretastatin derivate) in non-small-cell lung cancer (NSCLC), subsequently elucidating the underlying mechanisms. In human umbilical vein endothelial cells (HUVECs), DHPAC could enter cells and inhibit proliferation, migration, and angiogenesis in the presence and absence of conditioned medium from H1299 cells. Interestingly, the inhibition was enhanced under the stimulation of the conditioned medium. Under hypoxia or normoxia, DHPAC suppressed signal transducer and activator of transcription 3 phosphorylation and reduced vascular endothelial growth factor (VEGF) expression and secretion from HUVECs, thus impeding the activation of the downstream signal transduction pathway of VEGF/VEGFR2. However, JNK inhibitors reversed the inhibitory effect of DHPAC on the angiogenesis, suggesting that DHPAC regulated angiogenesis through activating JNK. In H1299 cells, DHPAC could inhibit proliferation, migration, invasion, and the formation of VM. In addition, DHPAC inhibited the phosphorylation of FAK and AKT and decreased the expressions of VEGF, matrix metalloproteinase 2 (MMP2), MMP9 and Laminin 5, suggesting that DHPAC inhibited VM formation via the FAK/AKT signaling pathway. In addition, CA4 showed a similar effect as DHPAC against angiogenesis and VM formation. These new findings support the use of microtubule destabilizing agents as a promising strategy for cancer therapy.

Abstract
Vascular mimicry is induced by a wide array of genes with functions related to cancer stemness, hypoxia, angiogenesis and autophagy. Vascular mimicry competent (VM-competent) cells that form de novo blood vessels are common in solid tumors facilitating tumor cell survival and metastasis. VM-competent cells display increased levels of vascular mimicry selecting for stem-like cells in an O2-gradient-dependent manner in deeply hypoxic tumor regions, while also aiding in maintaining tumor cell metabolism and stemness. Three of the principal drivers of vascular mimicry are EphA2, Nodal and HIF-1α, however, directly or indirectly many of these molecules affect VE-Cadherin (VE-Cad), which forms gap-junctions to bind angiogenic blood vessels together. During vascular mimicry, the endothelial-like functions of VM-competent cancer stem cells co-opt VE-Cad to bind cancer cells together to create cancer cell-derived blood conducting vessels. This process potentially compensates for the lack of access to blood and nutrient in avascular tumors, simultaneously providing nutrients and enhancing cancer invasion and metastasis. Current evidence also supports that vascular mimicry promotes cancer malignancy and metastasis due to the cooperation of oncogenic signaling molecules driving cancer stemness and autophagy. While a number of currently used cancer therapeutics are effective inhibitors of vascular mimicry, developing a new class of vascular mimicry specific inhibitors could allow for the treatment of angiogenesis-resistant tumors, inhibit cancer metastasis and improve patient survival. In this review, we describe the principal vascular mimicry pathways in addition to emphasizing the roles of hypoxia, autophagy and select proangiogenic oncogenes in this process.

CXCR2-Expressing Tumor Cells Drive Vascular Mimicry in Antiangiogenic Therapy-Resistant Glioblastoma. Neoplasia 2019; 20:1070-1082. [PMID: 30236892 PMCID: PMC6151844 DOI: 10.1016/j.neo.2018.08.011] [Citation(s) in RCA: 50] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 08/27/2018] [Accepted: 08/31/2018] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND: Glioblastoma (GBM) was shown to relapse faster and displayed therapeutic resistance to antiangiogenic therapies (AATs) through an alternative tumor cell-driven mechanism of neovascularization called vascular mimicry (VM). We identified highly upregulated interleukin 8 (IL-8)-CXCR2 axis in tumor cells in high-grade human glioma and AAT-treated orthotopic GBM tumors. METHODS: Human GBM tissue sections and tissue array were used to ascertain the clinical relevance of CXCR2-positive tumor cells in the formation of VM. We utilized U251 and U87 human tumor cells to understand VM in an orthotopic GBM model and AAT-mediated enhancement in VM was modeled using vatalanib (anti-VEGFR2) and avastin (anti-VEGF). Later, VM was inhibited by SB225002 (CXCR2 inhibitor) in a preclinical study. RESULTS: Overexpression of IL8 and CXCR2 in human datasets and histological analysis was identified as a bonafide candidate to validate VM through in vitro and animal model studies. AAT-treated tumors displayed a higher number of CXCR2-positive GBM-stem cells with endothelial-like phenotypes. Stable knockdown of CXCR2 expression in tumor cells led to decreased tumor growth as well as incomplete VM structures in the animal models. Similar data were obtained following SB225002 treatment. CONCLUSIONS: The present study suggests that tumor cell autonomous IL-8-CXCR2 pathway is instrumental in AAT-mediated resistance and VM formation in GBM. Therefore, CXCR2 can be targeted through SB225002 and can be combined with standard therapies to improve the therapeutic outcomes in clinical trials.

Abstract
Vasculogenic mimicry (VM) is a functional microcirculation pattern formed by aggressive tumor cells and is related to the metastasis and poor prognosis of many cancer types, including hepatocellular carcinoma (HCC). Thus far, no effective drugs have been developed to target VM. In this study, patients with liver cancer exhibited reduced VM in tumor tissues after treatment with Rhizoma Paridis. Polyphyllin I (PPI), which is the main component of Rhizoma Paridis, inhibited VM formation in HCC lines and transplanted hepatocellular carcinoma cells. Molecular mechanism analysis showed that PPI impaired VM formation by blocking the PI3k-Akt-Twist1-VE-cadherin pathway. PPI also displayed dual effects on Twist1 by inhibiting the transcriptional activation of the Twist1 promoter and interfering with the ability of Twist1 to bind to the promoter of VE-cadherin, resulting in VM blocking. This study is the first to report on the clinical application of the VM inhibitor. Results may contribute to the development of novel anti-VM drugs in clinical therapeutics.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Vasculogenic mimicry (VM) has been suggested to be present in various malignant tumors and associated with tumor nutrition supply and metastasis, leading to poor prognosis of patients. Notch1 has been demonstrated to contribute to VM formation in hepathocellular carcinoma (HCC). Celastrus orbiculatus extract (COE), a mixture of 11 terpenoids isolated from the Chinese Herb Celastrus orbiculatus Vine, has been suggested to be effective in cancer treatment. AIM OF THE STUDY In the current study, experiments were carried out to examine the effect of COE on VM formation and HCC tumor growth both in vitro and in vivo. MATERIALS AND METHODS CCK-8 assay and Nikon live-work station were used to observe the viability of malignant cells treated with COE. Cell invasion was examined using Transwell. Matrigel was used to establish a 3-D culture condition for VM formation. Changes of mRNA and protein expression were examined by RT-PCR and Western Blot respectively. Tumor growth in vivo was monitored using in vivo fluorescence imaging device. PAS-CD34 dual staining and electron microscopy were used to observe VM formation. Immunohistochemical staining (IHC) was used to examine Notch1 and Hes1 expression in tumor tissues. RESULTS Results showed that COE can inhibit HCC cells proliferation and invasion in a concentration-dependent manner. VM formation induced by TGF-β1 was blocked by COE. In mouse xenograft model, COE inhibited tumor growth and VM formation. Both in vitro and in vivo studies showed that COE can downregulate expression of Notch1 and Hes1. CONCLUSION The current results indicate that COE can inhibit VM formation and HCC tumor growth by downregulating Notch1 signaling. This study demonstrates that COE is superior to other anti-angiogenesis agents and can be considered as a promising candidate in HCC treatment.

Abstract
Glioblastoma (GBM) is a hypervascular neoplasia of the central nervous system with an extremely high rate of mortality. Owing to its hypervascularity, anti-angiogenic therapies (AAT) have been used as an adjuvant to the traditional surgical resection, chemotherapy, and radiation. The benefits of AAT have been transient and the tumors were shown to relapse faster and demonstrated particularly high rates of AAT therapy resistance. Alternative neovascularization mechanisms were shown to be at work in these resilient tumors to counter the AAT therapy insult. Vascular Mimicry (VM) is the uncanny ability of tumor cells to acquire endothelial-like properties and lay down vascular patterned networks reminiscent of host endothelial blood vessels. The VM channels served as an irrigation system for the tumors to meet with the increasing metabolic and nutrient demands of the tumor in the event of the ensuing hypoxia resulting from AAT. In our previous studies, we have demonstrated that AAT accelerates VM in GBM. In this review, we will focus on the origins of VM, visualizing VM in AAT-treated tumors and the development of VM as a resistance mechanism to AAT.

TXNDC5 is a cervical tumor susceptibility gene that stimulates cell migration, vasculogenic mimicry and angiogenesis by down-regulating SERPINF1 and TRAF1 expression. Oncotarget 2017; 8:91009-91024.

Abstract
TXNDC5 (thioredoxin domain-containing protein 5) catalyzes disulfide bond formation, isomerization and reduction. Studies have reported that TXNDC5 expression is increased in some tumor tissues and that its increased expression can predict a poor prognosis. However, the tumorigenic mechanism has not been well characterized. In this study, we detected a significant association between the rs408014 and rs7771314 SNPs at the TXNDC5 locus and cervical carcinoma using the Taqman genotyping method. We also detected a significantly increased expression of TXNDC5 in cervical tumor tissues using immunohistochemistry and Western blot analysis. Additionally, inhibition of TXNDC5 expression using siRNA prevented tube-like structure formation, an experimental indicator of vasculogenic mimicry and metastasis, in HeLa cervical tumor cells. Inhibiting TXNDC5 expression simultaneously led to the increased expression of SERPINF1 (serpin peptidase inhibitor, clade F) and TRAF1 (TNF receptor-associated factor 1), which have been reported to inhibit angiogenesis and metastasis as well as induce apoptosis. This finding was confirmed in Caski and C-33A cervical tumor cell lines. The ability to form tube-like structures was rescued in HeLa cells simultaneously treated with anti-TXNDC5, SERPINF1 and TRAF1 siRNAs. Furthermore, the inhibition of TXNDC5 expression significantly attenuated endothelial tube formation, a marker of angiogenesis, in human umbilical vein endothelial cells. The present study suggests that TXNDC5 is a susceptibility gene in cervical cancer, and high expression of this gene contributes to abnormal angiogenesis, vasculogenic mimicry and metastasis by down-regulating SERPINF1 and TRAF1 expression.

Abstract
Despite advanced screening technology and cancer treatments available today, metastasis remains an ongoing major cause of cancer-related deaths worldwide. Typically, colorectal cancer is one of the cancers treatable by surgery in conjunction with chemotherapy when it is detected at an early stage. However, it still ranks as the second highest modality and mortality of cancer types in western countries, and this is mostly due to a recurrence of metastatic colorectal cancer post-resection of the primary malignancy. Colorectal cancer metastases predominantly occur in the liver and lung, and yet the molecular mechanisms that regulate these organ-specific colorectal cancer metastases are largely unknown. Therefore, the identification of any critical molecule, which triggers malignancy in colorectal cancer, would be an excellent target for treatment. Netrin-1 was initially discovered as a chemotropic neuronal guidance molecule, and has been marked as a regulator for many cancers including colorectal cancer. Here, we summarise key findings of the role of netrin-1 intrinsic to colorectal cancer cells, extrinsic to the tumour microenvironment and angiogenesis, and consequently, we evaluate netrin-1 as a potential target molecule for metastasis.

Abstract
The aim of this study was to investigate the biologic role of the Rho kinase inhibitor fasudil in the vasculogenic mimicry (VM) of B16 mouse melanoma cells. It was previously reported that RhoA plays a critical role in angiogenesis by coordinating endothelial cell cytoskeleton remodeling and promoting endothelial cell motility. Although RhoA has been implicated in the regulation of angiogenesis, little has been described regarding its control of these tumor cell-lined channels. In this study, we established an in vitro model of VM using 3-dimensional cell culturing of mouse B16 melanoma cells and studied VM in vivo by transplanting B16 cells into C57/BL mice. Next, we explored the effect of RhoA and Rho-associated, coiled-coil containing protein kinase (ROCK) on VM formation using the Rho kinase inhibitor fasudil. We provide direct evidence that fasudil leads to reduced vascular-like channels in Matrigel. Additional experiments suggested that fasudil prevents both initial cellular architecture changes and cell migration in vitro. Finally, we provide in-depth evidence for the underlying mechanisms of fasudil-induced VM destruction using the Rho-GTPase agonist lysophosphatidic acid. In vivo studies revealed that fasudil reduced B16 melanoma cell xenograft tumor growth without causing significant toxicity in mice. Fasudil-treated tumors also displayed fewer VM channels. These results suggest that fasudil may be an emerging therapeutic option for targeting cancer VM.

Rytlewski JA, Alejandra Aldon M, Lewis EW, Suggs LJ. Mechanisms of tubulogenesis and endothelial phenotype expression by MSCs. Microvasc Res 2015; 99:26-35. [PMID: 25711526 DOI: 10.1016/j.mvr.2015.02.005] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2014] [Revised: 12/03/2014] [Accepted: 02/11/2015] [Indexed: 11/17/2022]
Abstract
Stem cell-based therapies are a promising new avenue for treating ischemic disease and chronic wounds. Mesenchymal stem cells (MSCs) have a proven ability to augment the neovascularization processes necessary for wound healing and are widely popular as an autologous source of progenitor cells. Our lab has previously reported on PEGylated fibrin as a unique hydrogel that promotes spontaneous tubulogenesis of encapsulated MSCs without exogenous factors. However, the mechanisms underlying this process have remained unknown. To better understand the therapeutic value of PEGylated fibrin delivery of MSCs, we sought to clarify the relationship between biomaterial properties and cell behavior. Here we find that fibrin PEGylation does not dramatically alter the macroscopic mechanical properties of the fibrin-based matrix (less than 10% difference). It does, however, dramatically reduce the rate of diffusion through the gel matrix. PEGylated fibrin enhances the tubulogenic growth of encapsulated MSCs demonstrating fluid-filled lumens by interconnected MSCs. Image analysis gave a value of 4320 ± 1770 μm total network length versus 618 ± 443 μm for unmodified fibrin. PEGylation promotes the endothelial phenotype of encapsulated MSCs--compared to unmodified fibrin--as evidenced by higher levels of endothelial markers (von Willebrand factor, 2.2-fold; vascular endothelial cadherin, 1.8-fold) and vascular endothelial growth factor (VEGF, up to 1.8-fold). Prospective analysis of underlying molecular pathways demonstrated that this endothelial-like MSC behavior is sensitively modulated by hypoxic stress, but not VEGF supplementation as evidenced by a significant increase in VEGF and MMP-2 secretion per cell under hypoxia. Further gain-of-function studies under hypoxic stress demonstrated that hypoxia culture of MSCs in unmodified fibrin could increase both vWF and VE-cadherin levels to values that were not significantly different than cells cultured in PEGylated fibrin. This result corroborated our hypothesis that the diffusion-limited environment of PEGylated fibrin is augmenting endothelial differentiation cues provided by unmodified fibrin. However, MSC networks lack platelet endothelial cell adhesion molecule-1 (PECAM-1) expression, which indicates incomplete differentiation towards an endothelial cell type. Collectively, the data here supports a revised understanding of MSC-derived neovascularization that contextualizes their behavior and utility as a hybrid endothelial-stromal cell type, with mixed characteristics of both populations.

Abstract
The aim of present investigation is to explore the molecular mechanisms of vasculogenic mimicry (VM) induced by hypoxia. Hepatocellular carcinoma cell lines were treated with CoCl2, and the VM-related parameters were assayed by real-time qPCR, Western blotting and immunofluorescence. Matrigel tube structure was also detected. We demonstrated that the expression of pMEK, MEK, pERK1/2 and ERK1/2 had a positive correlation with VM induced by hypoxia in MHCC97H while HepG2 signified VM under normoxia condition. PD98059 was negatively while epidermal growth factor positively participated in the increased tubes and area of VM. At the meaning time, the increased VM-related genes VE-cadherin, MMP2, MMP9, EphA2 and LAMC2 in hypoxia group were down-regulated by PD98059 in a dose-dependent manner. Furthermore, we elucidated that PKA, but not PKC, mediated the MEK/ERK pathway in a negative manner in VM. In conclusion, MEK/ERK pathway is positively involved in VM in hepatocellular carcinoma cell line, which was mediated by PKA negatively.

Abstract
Vasculogenic mimicry is a highly patterned vascular channel distinguished from the endothelium-dependent blood vessel. Vasculogenic mimicry is lined by highly aggressive tumor cells, and is associated with tumor grade, invasion and metastasis, and poor clinical prognosis. Much attention has been focused on the signaling pathways and the tumor microenvironment needed for vasculogenic mimicry formation, however, the studies on the spacial foundation for vasculogenic mimicry formation are limited. There are many lipid droplets in hepatocellular carcinoma due to steatosis, while increased numbers of lipid droplets also have been reported in many other neoplastic processes. The role of lipid droplets in tumor is still unclear. Based on the similar structural and morphological characteristics between vasculogenic mimicry and lipid droplet, we speculate that the lipid droplets may lay a spacial foundation for vasculogenic mimicry formation by a way of "space placeholder" in HCC. Experimental data and limited clinical literatures support the hypothesis to a certain degree. This hypothesis may provide a new idea for the study of vasculogenic mimicry and also provide a new direction for the functional study of lipid droplets in tumor.

Abstract
Malignant melanoma is one of the most aggressive cancers and can disseminate from a relatively small primary tumor and metastasize to multiple sites, including the lung, liver, brain, bone, and lymph nodes. Elucidating the molecular and genetic changes that take place during the metastatic process has led to a better understanding of why melanoma is so metastatic. Herein, we describe the unique features that distinguish melanoma from other solid tumors and contribute to the malignant phenotype of melanoma cells. For example, although melanoma cells are highly antigenic, they are extremely efficient at evading host immune response. Melanoma cells share numerous cell surface molecules with vascular cells, are highly angiogenic, are mesenchymal in nature, and possess a higher degree of 'stemness' than do other solid tumors. Finally, analysis of melanoma mutations has revealed that the gene expression profile of malignant melanoma is different from that of other cancers. Elucidating these molecular and genetic processes in highly metastatic melanoma can lead to the development of improved treatment and individualized therapy options.

Biochim Biophys Acta Rev Cancer 2013; 1836:273-86.

Abstract
Robust neovascularization and lymphangiogenesis have been found in a variety of aggressive and metastatic tumors. Endothelial sprouting angiogenesis is generally considered to be the major mechanism by which new vasculature forms in tumors. However, increasing evidence shows that tumor vasculature is not solely composed of endothelial cells (ECs). Some tumor cells acquire processes similar to embryonic vasculogenesis and produce new vasculature through vasculogenic mimicry, trans-differentiation of tumor cells into tumor ECs, and tumor cell-EC vascular co-option. In addition, tumor cells secrete various vasculogenic factors that induce sprouting angiogenesis and lymphangiogenesis. Vasculogenic tumor cells actively participate in the formation of vascular cancer stem cell niche and a premetastatic niche. Therefore, tumor cell-mediated neovascularization and lymphangiogenesis are closely associated with tumor progression, cancer metastasis, and poor prognosis. Vasculogenic tumor cells have emerged as key players in tumor neovascularization and lymphangiogenesis and play pivotal roles in tumor progression and cancer metastasis. However, the mechanisms underlying tumor cell-mediated vascularity as they relate to tumor progression and cancer metastasis remain unclear. Increasing data have shown that various intrinsic and extrinsic factors activate oncogenes and vasculogenic genes, enhance vasculogenic signaling pathways, and trigger tumor neovascularization and lymphangiogenesis. Collectively, tumor cells are the instigators of neovascularization. Therefore, targeting vasculogenic tumor cells, genes, and signaling pathways will open new avenues for anti-tumor vasculogenic and metastatic drug discovery. Dual targeting of endothelial sprouting angiogenesis and tumor cell-mediated neovascularization and lymphangiogenesis may overcome current clinical problems with anti-angiogenic therapy, resulting in significantly improved anti-angiogenesis and anti-cancer therapies.

Different role of COX-2 and angiogenesis in canine inflammatory and non-inflammatory mammary cancer. Vet J 2013; 197:427-32.

Abstract
Human inflammatory breast cancer (IBC) and canine inflammatory mammary cancer (IMC) are the most aggressive and fatal types of mammary cancer, and both have a very poor prognosis and low survival rate. Human IBC is characterised by exacerbated angiogenesis, lymphangiogenesis, and lymphangiotropism. Lymphangiotropism is also characteristic of IMC, but microvascular density (MVD) and lymphangiogenesis have not been previously studied in canine IMC. In this study immunohistochemical expression of several angiogenesis-related factors (cyclooxygenase [COX]-2, vascular endothelial growth factors A and D [VEGF-A, VEGF-D], and vascular endothelial growth factor receptor 3 [VEGFR-3]), MVD, lymphatic proliferation index (LPI), and Ki-67 tumour proliferation index (PI) were studied in 21 canine IMC samples, 20 canine high-grade malignant non-IMC mammary tumours (MMTs), and four normal mammary gland samples (NMGs). All mammary neoplasms were histologically categorised as grade III. COX-2 values were also analysed by RT-PCR in seven IMCs, six MMTs and four NMGs. The expressions of COX-2, VEGF-A, and VEGF-D were significantly higher in IMC, MVD and LPI tumours, but not PI. In MMTs, COX-2 immunoexpression was significantly associated with VEGF-A, while in IMCs COX-2 was associated with VEGF-D (lymphangiogenic factor), its receptor VEGFR-3, and LPI. These results suggested that lymphangiogenic pathway stimulation isa specific role of COX-2 in IMC angiogenesis, which justifies the use of COX-2-based targeted palliative therapies in dogs. The exacerbated angiogenesis and lymphangiogenesis and the increased expression of angiogenesis-related factors further support canine IMC as a natural model for the study of human IBC.
