BACKGROUND: Breast cancer is an alarming global public health problem and a main cause of cancer-related death in women. Systemic chemotherapy is the most widely used treatment for breast cancer. However, current chemotherapy treatments are far from desirable due to poor targeting specificity, severe side effects, and vasculogenic mimicry (VM). PURPOSE: Hyaluronic acid (HA) modified daunorubicin plus honokiol cationic liposomes were prepared and characterized for treatment of breast cancer by eliminating VM...

Vasculogenic mimicry refers to the process by which highly invasive cancer cells mimic endothelial cells by forming blood channels. Vasculogenic mimicry is important for the invasion and metastasis of tumor cells in colorectal cancer. STAT3 was initially identified as a mediator of the inflammation-associated acute phase response. The phosphorylation of Signal Transducers and Activators of Transcription 3 (p-STAT3) is closely related to tumor invasion and migration. We analyzed the relationship between p-STAT3 and vasculogenic mimicry formation in 65 human colorectal cancer samples, and the results showed that the expression of p-STAT3 is significantly correlated with vasculogenic mimicry, tumor metastasis, Tumor, Lymph Node and Metastasis Stage (TNM Stage), and poor prognosis...

Background: Anti-angiogenesis therapy that targets VEGF is one of the important treatment strategies in advanced ovarian cancer. However, depending on the pharmaceutical agent, treatment can have undesirable side effects. SEMA4D has recently gained interest for its role in promoting angiogenesis. Here, we try to further understand the mechanism by which SEMA4D promotes angiogenesis in ovarian cancer. Methods: Correlation and western blot assaya were used to detect the relationship between VEGF and SEMA4D in clinical tissues and cells...

OBJECTIVE: To explore the influence of Beclin-1 on vasculogenic mimicry (VM) induced by hypoxia in glioma. METHODS: CD34-PAS staining was carried out to observe VM formation, and immunohistochemistry was used to determine the expression levels of Beclin-1, HIF-1α, VEGF and MMP2 in 105 patients with primary glioma. Human glioma U87MG cells were divided into Normoxia, Hypoxia, Hypoxia + NC siRNA and Hypoxia + Beclin-1 siRNA groups. Cobalt chloride (CoCl2) was used to stimulate hypoxic conditions, and a VM tube formation assay was used to detect VM formation...

Tumors require nutrients and oxygen for growth and metastasis. Vasculogenic mimicry (VM) has been found as a new manner of blood supply, which is characterized as the formation of tumor cell-lined vessels instead of endothelial vessels. This is why angiogenesis agents targeted to endothelial cells show a limited efficacy. Up to this point, there is no effective drug reported for inhibiting VM formation. Niclosamide is an oral anti-helminthic drug used to treat human tapeworms. Recent studies have indicated that niclosamide has broad applications for cancer and other diseases...

Migration-inducing gene 7 (MIG7) is highly expressed and is implicated in multiple malignant tumors with vasculogenic mimicry (VM) which renders possible routes without the endothelium for invasion and metastasis. However, there are few reports in the literature describing the relationship between MIG7 expression and VM formation in hepatocellular carcinoma (HCC). In the present study, we found a significantly positive correlation between MIG7 expression and VM in 40 HCC specimens. Three-dimensional (3D) culture showed that VM formation in the HCC cell line MHCC-97H with high metastatic potential was enhanced to a greater extent than that of MHCC-97L and Huh-7 with low and non-metastatic potential...

By using human melanoma and glioblastoma cell lines and their derivative BCL-XL overexpressing clones, we investigated the role of BCL-XL in aggressive features of these two tumor histotypes. We found that in both models, BCL-XL overexpression increased in vitro cell migration and invasion and facilitated tumor cells to form de novo vasculogenic structures. Furthermore, BCL-XL overexpressing cells exhibited higher tumors sphere formation capacity and expressed higher levels of some stem cell markers, supporting the concept that BCL-XL plays essential roles in the maintenance of cancer stem cell phenotype...

Ectopic expression of netrin-1 has been validated in several cancers including non-small cell lung cancer (NSCLC). Recent research confirms the critical role of netrin-1 in NSCLC growth and its prognostic value. Unfortunately, its contribution in NSCLC metastasis remains elusive. Here, netrin-1 had relatively high expression in NSCLC tissues and cells, especially in high metastatic groups. Notably, netrin-1 overexpression aggravated the malignant metastatic behavior of NSCLC cells, including cell invasion, migration, and vasculogenic mimicry (VM), whereas netrin-1 depression reversely dampened the metastatic potential...

Breast cancer is one of the most serious malignant tumors that harm to women's health. Vasculogenic mimicry (VM) is an alternative type of blood supplement independent of endothelial vessels, which refers to the formation of tumor cell-lined vessels and is associated with tumor invasion, metastasis and poor cancer patient prognosis. Prior antiangiogenic therapy just focused on vascular endothelial cells and did not significantly affect VM. DMBT, 6, 6'-bis (2, 3-dimethoxybenzoyl)-a, a-D-trehalose, has shown to have multiple anti-tumor invasion and metastasis activities; however the exact mechanism is not thoroughly elucidated...

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...

Vasculogenic mimicry process has generated great interest over the past decade. So far, however, there have been only a few matrices available that allow us to study that process in vitro. Here, we have developed an innovative hydrogel platform with defined composition that mimics the structural architecture and biological functions of the extracellular matrix for vasculogenic mimicry of human melanoma cells (SK-MEL-28). We chemically immobilized IKVAV peptide on bacterial nanocellulose (BNC) fibers. BNC-IKVAV hydrogel was found to improve the adhesion and proliferation of SK-MEL-28 cells on the top and bottom surfaces...

Vasculogenic mimicry (VM) constitutes a novel approach for tumour blood supply and contributes to tumour metastasis and poor prognosis in patients with melanoma. Myoferlin (MYOF), a type II membrane protein involved in membrane regeneration and repair, is elevated in several malignant tumours, especially in advanced melanomas. This study aims to investigate the role and mechanism of MYOF in the regulation of VM. VM structures were found in 14 of 52 tested melanoma samples, and high MYOF expression correlated with VM structures...

The topographical organization of collagen within the tumor microenvironment has been implicated in modulating cancer cell migration and independently predicts progression to metastasis. Here, we show that collagen matrices with small pores and short fibers, but not Matrigel, trigger a conserved transcriptional response and subsequent motility switch in cancer cells resulting in the formation of multicellular network structures. The response is not mediated by hypoxia, matrix stiffness, or bulk matrix density, but rather by matrix architecture-induced β1-integrin upregulation...

Various aggressive cancers, including pancreatic cancer, produce functional blood vessels by neovascularization. Tumor vasculogenic mimicry (VM) promotes cancer progression and is closely associated with the poor prognosis of the cancer patients. Therefore, tumor VM is a sensible target for novel anti-cancer drug discovery. However, there is a lack of effective anti-tumor VM drugs in the clinical setting. In this study, we aim to explore novel agents to effectually inhibit pancreatic cancer cell-mediated tumor VM for anti-cancer therapy...

Neuroblastoma is a vascularized pediatric tumor derived from neural crest stem cells that displays vasculogenic mimicry and can express a number of stemness markers, such as SOX2 and NANOG. Tumor relapse is the major cause of succumbing to this disease, and properties attributed to cancer stem-like cells (CSLC), such as drug-resistance and cell plasticity, seem to be the key mechanisms. However, the lack of controllable models that recapitulate the features of human neuroblastoma limits our understanding of the process and impedes the development of new therapies...

Hepatoblastoma (HB) is the most common type of pediatric liver malignancy, which predominantly occurs in young children (aged <5 years), and continues to be a therapeutic challenge in terms of metastasis and drug resistance. As a new pattern of tumor blood supply, vasculogenic mimicry (VM) is a channel structure lined by tumor cells rather than endothelial cells, which contribute to angiogenesis. VM occurs in a variety of solid tumor types, including liver cancer, such as hepatocellular carcinoma. The aim of the present study was to elucidate the effect of arsenic trioxide (As2O3) on VM...

Transmembrane 4 L six family member 5 (TM4SF5) is highly expressed in hepatocellular carcinoma tissues and enhances migration in two-dimensional environments. Here, we investigated how TM4SF5 is involved in diverse pro-metastatic phenotypes in in vivo-like three-dimensional (3D) extracellular matrix gels. TM4SF5-positive cells aggressively formed invasive foci in 3D Matrigel, depending on TM4SF5-mediated signaling activity, cytoskeletal organization, and matrix metallopeptidase (MMP) 2-mediated extracellular remodeling, whereas TM4SF5-null cells did not...

Macrophage migration inhibitory factor (MIF) is over-expressed and secreted in various cancer cells in particular in response to hypoxia. Recent studies have shown that, under hypoxic conditions, glioblastoma (GBM) cells display the ability to drive blood-perfused vasculogenic mimicry (VM). The aim of this study was to investigate the underlying mechanism of MIF in the regulation of hypoxia-induced VM in GBM cells. By analyzing clinical specimens, we observed the co-localization of MIF, C-X-C motif chemokine receptor 4 (CXCR4) and VM in hypoxic regions of gliomas...
