Vasculogenic mimicry (VM) refers to the condition in which tumour cells mimic endothelial cells to form extracellular matrix-rich tubular channels. VM is more extensive in more aggressive tumours. The human epidermal growth factor receptor 2 (HER2) gene is amplified in 20-30% of human breast cancers and has been implicated in mediating aggressive tumour(More)
Vasculogenic mimicry (VM) refers to the unique capability of aggressive tumour cells to mimic the pattern of embryonic vasculogenic networks. Epithelial-mesenchymal transition (EMT) regulator slug have been implicated in the tumour invasion and metastasis of human hepatocellular carcinoma (HCC). However, the relationship between slug and VM formation is not(More)
To evaluate the prognostic value of OCT4 expression and vasculogenic mimicry (VM) in human breast cancer, we examined OCT4 expression and VM formation using immunohistochemistry and CD31/PAS (periodic acid-schiff) double staining on 90 breast cancer specimens. All patients were followed up for five-149 months following surgery. Survival curves were(More)
BACKGROUND Highly aggressive tumors are exposed to hypoxia and increased tumor interstitial fluid pressure (IFP) conditions which is resistant to blood supply. Physiological responses of the organism may reduce IFP through induction of orderly cell death. SPECIFIC AIMS This study demonstrates that orderly cell death provided spatial structure for early(More)
Tumor cell vasculogenic mimicry (VM), a newly defined pattern of tumor blood supply, signifies the functional plasticity of aggressive cancer cells forming vascular networks. VM and cancer stem cells (CSCs) have been shown to be associated with tumor growth, local invasion, and distant metastasis. In our previous study, CSCs in triple-negative breast cancer(More)
