BACKGROUND Dendritic cell (DC)-based tumor vaccine is an attractive modality for the treatment of colon cancer because it has been recurred and produced few side effects in patients. Secretory glycoprotein 90K has been found at elevated level in various cancer tissues and sera. We investigated to establish a more effective DC vaccine for the treatment of colon cancer in which the levels of 90K ...

Glycoprotein 90K (also known as LGALS3BP or Mac-2BP) is a tumor-associated protein, and high 90K levels are associated with poor prognosis in some cancers. To clarify the role of 90K as an indicator for poor prognosis and metastasis in epithelial cancers, the present study investigated the effect of 90K on an adherens junctional protein, E-cadherin, which is frequently absent or downregulated i...

90K, also known as Mac-2 binding protein, is a secreted glycoprotein that binds galectins, beta1-integrins, collagens, and fibronectin, and has some relevance in cell-cell and cell-extracellular matrix adhesion. Previous studies have shown that serum levels of 90K have prognostic value in several neoplasms. In the present study, the role of the expression of 90K as an adverse prognostic indicat...

A cell-adhesive protein of the human serum, 90K binds galactin-3, beta1-integrins, collagens, and fibronectin, and it is of importance in cell-cell and cell-extracellular matrix adhesion. Serum 90K levels in 137 patients with lymphoma were measured by enzyme-linked immunosorbent assay. Compared with healthy controls, pretreatment serum 90K levels in patients with lymphoma were elevated (P <.001...

β-Catenin is a major transducer of the Wnt signaling pathway, which is aberrantly expressed in colorectal and other cancers. Previously, we showed that β-catenin is downregulated by the 90K glycoprotein via ISGylation-dependent degradation. However, the further mechanisms of β-catenin degradation by 90K-mediated ISGylation pathway were not investigated. This study aimed to identify the β-cateni...

Expression levels of the immunostimulatory 90K antigen in mammary carcinoma, glioblastoma, and other tumor-derived cell lines inversely correlate with their tumorigenicity in athymic mice. Engineered enhancement of 90K expression results in significant (> 80%) tumor growth inhibition, not by direct action on the tumor cell, but by stimulation of the residual cell-mediated immune defense of the ...

Tumor development involves complex bidirectional interactions between tumor cells and host stromal cells. Endosialin (Tem1) has been identified as a highly O-glycosylated transmembrane glycoprotein, which is specifically expressed by tumor vessel-associated pericytes and stromal fibroblasts of a wide range of human tumors. Recent experiments in endosialin-deficient mice have unraveled a critica...

BACKGROUND The simultaneous correlation of serum galectin-1, galectin-3, and 90K/Mac-2BP levels with clinical stages of patients with colorectal cancer has not yet been clarified. We plan to measure the serum levels of galectin-1, galectin-3, and 90K/Mac-2BP of patients at different stages of colorectal cancer and analyze the correlation of these galectins with stages of colorectal cancers. M...
