Vasculogenic mimicry (VM) is a blood supply system independent of endothelial vessels in tumor cells from different origins. It reflects the plasticity of aggressive tumor cells that express vascular cell markers and line tumor vasculature. The presence of VM is associated with a high tumor grade, short survival, invasion and metastasis. Endothelial cells (ECs) express various members of the cadherin superfamily, in particular vascular endothelial (VE-) cadherin, which is the main adhesion receptor of endothelial adherent junctions...

BACKGROUND/AIM: The ability of a tumor to grow requires a sufficient blood supply. Microvascular density is considered the standard for assessing the neovasculature. Tumor cell vasculogenic mimicry refers to the formation of tumor cell-lined vessels that contribute to tumor neovascularization. The aim of the present work was to study angiogenesis and vasculogenic mimicry in benign and malignant melanocytic tumors of the eye and the periocular region. PATIENTS AND METHODS: Histological sections from 118 patients were studied...

Agents that target angiogenesis have shown limited efficacy for human triple-negative breast cancer (TNBC) in clinical trials. Along with endothelium-dependent vessels, there is also vasculogenic mimicry (VM) in the microcirculation of malignant tumors. The role of VM is not completely understood regarding anti-angiogenic treatment. In this study, human TNBC MDA-MB-231 and Hs578T and non-TNBC MCF-7 and BT474 tumor-bearing mice were treated with sunitinib, an anti-angiogenic drug, using a clinically relevant schedule...

MALAT1 is an oncogenic long non-coding RNA that has been found to promote the proliferation of many malignant cell types and non-malignant human umbilical vein endothelial cells (HUVECs). However, the functions of MALAT1 in vasculogenic mimicry (VM) and angiogenesis and the potential mechanisms responsible have not yet been investigated in any malignancy. Here, in situ hybridization and CD31/periodic acid-Schiff double staining of 150 gastric cancer (GC) clinical specimens revealed that MALAT1 expression was tightly associated with densities of VM and endothelial vessels...

The transcription factor Runx2 has been reported to promote epithelial-mesenchymal transition (EMT) in many tumors. Vasculogenic mimicry (VM) is described as the mimicry of endothelial cells by tumor cells to form microvascular tubes in aggressive tumors. Galectin-3 has been reported to regulate cell invasion, migration, and VM formation; it could be regulated by Runx2. However, the relationship between Runx2, Galectin-3, EMT, and VM has not been studied in hepatocellular carcinoma (HCC). We examined Runx2 expression in 89 human HCC samples and found Runx2 expression was associated with VM...

Purpose: We previously reported that polyploid giant cancer cells (PGCCs) induced by cobalt chloride (CoCl2) exhibit cancer stem cell properties. Daughter cells generated by PGCCs possess epithelial mesenchymal transition (EMT) phenotype changes and EMT plays an important role in cancer development and progression. This study investigated the characteristics of PGCCs from LoVo and HCT116 induced by CoCl2 and the clinicopathological significances of PGCCs in colorectal cancer (CRC). Materials and Methods: Western blotting and immunocytochemical staining were used to compare the expression levels of EMT-related proteins between PGCCs with budding daughter cells and the control cells...

BACKGROUND: Recurrence and metastasis are the usual manifestations of treatment failure of epithelial ovarian carcinoma (EOC). Vasculogenic mimicry (VM; blood supply development often seen in highly aggressive cancers), aldehyde dehydrogenase 1 (ALDH1, cancer stem cell biomarker), KiSS-1 (suppressor of tumor metastasis), and metastasis associated in colon cancer-1 (MACC1) are all useful predictive factors for metastasis and prognosis in various cancers. In this study, we analyzed associations among VM, ALDH1, KiSS-1, and MACC1 in EOC, and their respective correlations with clinicopathological characteristics and survival in EOC...

GTPase RhoA and its downstream Rho-associated coiled-coil-containing protein kinases (ROCKs) are frequently overexpressed in human cancers. Inhibition of the RhoA/ROCK pathway blocks angiogenesis mediated by the vascular endothelial growth factor, which led us to investigate the role of this pathway in vasculogenic mimicry (VM) - a process by which aggressive cancer cells form vessel-like structures that provide adequate blood supply for tumor growth. We showed that the expression of RhoA and its effector kinases ROCK1/2 was much higher in human osteosarcoma (OS) tissues and the human OS cell line U2OS than in nontumorous tissues and cell line hFOB 1...

Melanoma is among the most virulent cancers, owing to its propensity to metastasize and its resistance to current therapies. The treatment failure is largely attributed to tumor heterogeneity, particularly subpopulations possessing stem cell-like properties, ie, melanoma stem-like cells (MSLCs). Evidence indicates that the MSLC phenotype is malleable and may be acquired by non-MSLCs through phenotypic switching upon appropriate stimuli, the so-called 'dynamic stemness'. Since the phenotypic characteristics and functional integrity of MSLCs depend on their vascular niche, using a two-dimensional (2D) melanoma-endothelium co-culture model, where the MSLC niche is recapitulated in vitro, we identified Notch3 signaling pathway as a micro-environmental cue governing MSLC phenotypic plasticity via pathway-specific gene expression arrays...

Vasculogenic mimicry (VM) is a non-classical mechanism recently described in many tumors, whereby cancer cells, rather than endothelial cells, form blood vessels. Transgelin is an actin-binding protein that has been implicated in multiple stages of cancer development. In this study, we investigated the role of transgelin in VM and assessed its effect on the expression of endothelial and angiogenesis-related genes during VM in MDA-MB-231 breast cancer cells. We confirmed the ability of MDA-MB-231 cells to undergo VM through a tube formation assay...

Bcl-2 and Twist1 can be coactivated by hypoxia in hepatocellular carcinoma to promote tumor cell metastasis and vasculogenic mimicry, but their function in oral squamous cell carcinoma (OSCC) remains undefined. We employed a cohort of 82 cases of OSCC samples to examine the coexpression of Bcl-2 and Twist1 by immunohistochemistry and demonstrate the interaction between Bcl-2 and Twist1 by coimmunoprecipitation. Bcl-2 and Twist1 overexpression was associated with a poor pathological grade and tumor prognosis, and the two factors functions as a complex...

Vasculogenic mimicry, the process in which cancer cells form angiomatoid structures independent of or in addition to host angiogenesis has been recorded in several otherwise non-endothelial malignant neoplasms. This study describes evidence of routine vascular mimicry by human mesothelioma cell lines in vitro, when the cell lines are cultured alone or co-cultured with human umbilical vascular endothelial cells, with the formation of angiomatoid tubular networks. Vasculogenic mimicry is also supported by immunohistochemical demonstration of human-specific anti-mitochondria antibody labelling of tumour-associated vasculature of human mesothelioma cells xenotransplanted into nude mice, and by evidence of vascular mimicry in some biopsy samples of human malignant mesotheliomas...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive human malignancies. The Yes-associated protein-1 (YAP) plays a critical role in cell proliferation, apoptosis and angiogenesis. Verteporfin is a photosensitizer used in photodynamic therapy and also a small molecular inhibitor of the Hippo-YAP pathway. However, little is known whether verteporfin could inhibit YAP activity in PDAC cells. Our present results showed that verteporfin suppressed the proliferation of human PDAC PANC-1 and SW1990 cells by arresting cells at G1 phase, and inducing apoptosis in dose- and time-dependent manners...

A highly invasive Du145-III subline was isolated by three successive passages of the parental Du145 prostate tumor cell line (Du145-P) through a Boyden chamber with matrigel-coated membrane support. Du145-III cells showed great invasion potential based on their increased ability to spread/migrate and enhanced expression/secretion of the matrix metalloproteinase 9 (MMP9). Du145-III cells exerted vasculogenic mimicry (VM) properties, reminiscent of endothelial cell characteristics and expressed elevated levels of cancer stem cell (CSC) markers, including Nanog, Sox2, CD44 and ABCG2 and ability to self-renew...

Vasculogenic mimicry (VM) has offered a new horizon for understanding tumor angiogenesis, but the mechanisms of VM in glioma progression have not been studied explicitly until now. As a significant component of immune infiltration in tumor microenvironment, macrophages have been demonstrated to play an important role in tumor growth and angiogenesis. However, whether macrophages could play a potential key role in glioma VM is still poorly understood. Herein we reported that both VM and CD163+ cells were associated with WHO grade and reduced patient survival, and VM channel counting was correlated to the number of infiltrated CD163+ cells in glioma specimens...

OBJECTIVE: To explore the inhibitory effect of migration-inducing gene 7 (Mig-7) gene silencing induced by retroviral-mediated small hairpin RNA (shRNA) on vasculogenic mimicry (VM), invasion and metastasis of human hepatocellular carcinoma (HCC) cells in vitro. METHODS: Two target sequences (Mig-7 shRNA-1 and Mig-7 shRNA-2) and one negative control sequence (Mig-7 shRNA-N) were synthesized. The recombinant retroviral vectors carrying Mig-7 shRNA were constructed, and HCC cell line MHCC-97H were transfected with Mig-7 shRNA-1, Mig-7 shRNA-2, Mig-7 shRNA-N, or the empty vector, or treated with 125 µg/mL recombinant human endostatin (ES)...

We report in this study that microRNA-584-3p (miR-584-3p) is related to the vasculogenic mimicry (VM) of human glioma cells. Unsurprisingly, the postoperative survival time was significantly prolonged in those glioma patients without VM phenomena compared with those with positive VM. miR-584-3p may function as a potent tumor suppressor by inhibiting VM of malignant glioma. However, the molecular mechanisms underlying these properties remain poorly understood. Our preliminary mechanistic studies revealed that miR-584-3p suppressed the VM by disturbing hypoxia-induced stress fiber formation and migration of glioma cells...
