To investigate on expressions and clinical significances of CD133 protein and vasculogenic mimicry (VM) in primary non-small cell lung cancer (NSCLC). The specimens of NSCLC from 305 Chinese patients with follow-up were analyzed for CD133 protein expression and VM by immunohistochemical and histochemical staining. In NSCLC, positive rates of 48.9% and 35.7%(More)
BACKGROUND Breast cancer is the leading cause of cancer death in females worldwide, and the majority type is infiltrating ductal carcinoma (IDC). Most of IDC patients died of metastasis and recurrence. Cancer stem cells (CSCs) are defined with the ability to be self-renewal and potentially promote proliferation and formation of tumors. CSCs are related to(More)
OBJECTIVE To investigate the antineoplastic effects of 2-Deoxy-D-glucose (2-DG) combined with Taxol on orthotopically transplanted breast cancer in C3H mice and explore the mechanism. METHODS C3H mice bearing orthotopically transplanted breast cancer xenograft were randomly divided into 4 groups, namely the control group, 2-DG group, Taxol group, and(More)
OBJECTIVE To investigate the presence of cancer stem cells (CSCs) exist in non-small cell lung cancer (NSCLC) and explore the relationship among the expressions of CD133, Notch1, and vascular endothelial growth factor (VEGF) and their relations with the clinicopathological parameters of the patients. METHODS A total of 305 specimens of NSCLC and 80 normal(More)
Esophageal squamous cell carcinoma (ESCC) is a predominant type of esophageal cancer, which is a malignant tumor originating from the esophageal mucosa or gland and is aggressive with poor prognosis. Identification of new gene expression patterns would be helpful for providing new targets for the early detection and treatment of ESCC patients. In the(More)
BACKGROUND AND OBJECTIVE Vasculogenic mimicry (VM), found in many high invasive ability tumors, is associated with tumor invasion and metastasis. Many genes exhibit abnormal levels of expression in these tumors. This study aims to find good markers for predicting the invasion and metastasis of non-small cell lung cancer (NSCLC). METHODS VM and expression(More)
The aim of this study was to investigate KAI1/CD82 protein expression in human nasopharyngeal carcinoma (NPC) cell lines and human NPC tissues. Immunohistochemistry and western blot analysis were used to detect the localization and expression levels of the KAI1/CD82 protein in five human NPC cell lines. Immunohistochemistry was also conducted to detect the(More)
OBJECTIVE To investigate the correlation between infection with L-form of Helicobacter pylori (Hp-L) and the expressions of macrophage migration inhibition factor (MIF), matrix metalloproteinase 9 (MMP9), and vascular endothelial growth factor (VEGF) in gastric cancer. METHODS Hp-L was examined in 80 gastric carcinoma and 50 adjacent normal tissues by(More)
Abnormal activation of Wnt signaling pathway is closely related to the occurrence of tumor, and T cell factor 4 (Tcf4 ) and beta-catenin are important signal transmission factors of this pathway. The aim of the present study is to explore the significance and correlation between expression of Tcf4, beta-catenin and secreted frizzled related protein(More)
The present paper aims to investigate whether or not vasculogenic mimicry (VM) exists in laryngeal squamous cell carcinoma (LSCC), and to elucidate its relationship to microvessel density (MVD), galectin-3 (Gal-3) expression, and clinicopathological factors of patients with LSCC. VM, score of MVD and expression of Gal-3 protein were detected by(More)
