swainsonine/breast neoplasms

OBJECTIVE To investigate the effect of N-glycan-defective mammary adenocarcinoma cells on the polarization of macrophages. METHODS N-glycan-defective breast cancer cells (MA782 cells) were prepared by swainsonine (SW) treatment and the cytotoxicity of SW to MA782 cells was evaluated using the

Expression of beta 1-6 branched oligosaccharides in human breast cancer cells was investigated in vivo and in vitro. Lectin histochemical and lectin blotting analyses of surgically resected specimens were performed using L-PHA (phaseolus vulgaris leukoagglutinin) lectin, which binds to beta 1-6

Integrins are the major cell adhesion glycoproteins involved in cell-extracellular matrix (ECM) interaction and metastasis. Further, glycosylation on integrin is necessary for its proper folding and functionality. Herein, differential expression of integrins viz., αvβ3 and αvβ6 was examined in

Tumor progression in rodent and human tumors is commonly associated with changes in glycoprotein glycosylation, in particular increased beta 1-6GlcNAc-branching, a regulatory step in expression of polylactosamine and extended-chain Lewis antigens. Loss of the branched oligosaccharides in murine
