The glycosyl nature of the receptor for the peptide hormone calcitonin has been investigated in a human breast cancer cell line, T 47D. Studies have been carried out to assess the ability of various lectins and of the antibiotic tunicamycin to inhibit specific binding of calcitonin to the cells, to

The alpha2,3 sialyltransferase, alpha2,3 SAT (O), catalyzes the transfer of sialic acid to Galbeta1,3 N-acetyl-D-galactosamine (GalNAc) (core-1) in mucin type O-glycosylation, and thus terminates chain extension. A Core-2 branch can also be formed from core-1 by the core-2 beta1,6

Disseminated metastasis accounts for over 90% of breast cancer deaths. Recently, elevated serum levels of a glycoprotein known as chitinase-3 like-protein-1 (CHI3L1) has been correlated with poor prognosis and shorter survival of patients with metastatic breast cancer. In this study, we show that

The monoclonal antibody LU-BCRU-G7, that was generated by in vitro immunization, shows clinical value as a prognostic marker in early stage breast carcinoma. It has now been characterized with regard to its binding epitope. Using a recently described method based on the construction of N-substituted

Membrane glycoprotein with high Mr (HMr-MGP) was purified from neuraminidase-treated Triton X-100-solubilized human milk-fat-globule membranes by peanut-agglutinin (PNA) affinity chromatography. The high carbohydrate content (75%), blood-group-A activity and typical monosaccharide composition

Hyaluronic acid (HA) is a component of the extracellular matrix (ECM) that exists as a high molecular weight polymer composed of alternating disaccharides, D-glucuronic acid and N-acetyl D-glucosamine. The interaction of hyaluronidase with HA results in the disruption of basement membrane integrity

Cancer cells, which use more glucose than normal cells and accumulate extracellular lactate even under normoxic conditions (Warburg effect), have been reported to undergo cell death under glucose deprivation, whereas normal cells remain viable. As it may be relevant to exploit the molecular
