d galactose/breast neoplasms

OBJECTIVE This study sought to evaluate prospectively the diagnostic potential of unenhanced and enhanced color Doppler and power Doppler for the differentiation of tumors and tumorlike lesions of the breast. METHODS Ninety-two patients with 110 tumors or tumorlike lesions of the breast were

Isolated caprine epididymal plasma glycoprotein "anti sticking factor" (ASF) interacts with caudal sperm surface in a D-galactose dependent manner. ASF acts as a Ca(2+) dependent soluble lectin principally activated in acidic pH. As a D-galactose specific lectin, it has a specific affinity for

Mixtures of the T-47D human breast cancer cell line and normal human bone marrow cells were used for studying a new approach for purging epithelial tumor cells for autologous bone marrow transplantation (BMT) in breast cancer. Breast cancer cell line T-47D cells were shown to bind soybean agglutinin

In our previous report, monoclonal antibody PR92 has defined prostate- and breast tumor-associated PR92 antigen. The molecular nature of PR92 antigen, especially the epitope involved in specific interaction with PR92 monoclonal antibody, is described. PR92 antigen was purified from the cell extract

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

Endogenous lectins may augment the panel of tumor markers. Specific protein-carbohydrate interactions especially involve carbohydrate moieties that are located at sequence termini, e.g. D-galactose and N-acetyl-D-galactosamine. Respective endogenous lectins can be detected by suitably constructed

A dimeric 62-kDa lectin exhibiting a novel N-terminal amino acid sequence was purified from caper (Capparis spinosa) seeds. The purification protocol involved anion-exchange chromatography, cation-exchange chromatography and, finally, gel filtration by FPLC on Superdex 75. Approx. 100-fold

Three marine invertebrate FITC-labelled lectins, CNL, GCL, and GSL, isolated respectively, from the sponges Chondrilla nucula, Geodia cydonium, and the hexacoral Gerardia savaglia, were used as potential diagnostic tools for different breast tumors. The lectins vary in their carbohydrate binding

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

Serum protein-bound carbohydrates, L-fucose, sialic acid, D-galactose, and D-mannose, were measured as potential biologic markers in patients with breast cancer with the use of high-resolution anion exchange separation in combination with a sensitive cerate oxidimetric fluorescence detector system.

2-Deoxy-2-[(18)F]fluoro-D-glucose (2-(18)FDG) has represented radiofluorinated carbohydrates as the most successful tracer for positron emission tomography (PET). 2-(18)FDG uptake depends on glucose metabolism, which is related to a disease progression. 2-(18)FDG has been widely used in oncology,

The transformation from normal to malignant phenotype in human cancers is associated with aberrant cell-surface glycosylation. Thus, targeting glycosylation changes in cancer is likely to provide not only better insight into the roles of carbohydrates in biological systems, but also facilitate the

OBJECTIVE Prospective comparison of plain and signal-enhanced frequency and amplitude-modulated colour Doppler ultrasound of intramammary tumours to evaluate new criteria for diagnostic analysis. METHODS Frequency and amplitude-modulated colour Doppler examination with qualitative and quantitative

The galactoside-specific plant lectin, Viscum album agglutinin (VAA-I) increases cellular parameters of natural host defence. It also binds to a variety of haematopoietic cells, including progenitors. We investigated whether VAA-I has a stimulatory effect on haematopoietic progenitor cells.

Doxorubicin, an anthracycline from Streptomyces peucetius, exhibits antitumor activity against various cancers. However, doxorubicin is cardiotoxic at cumulative doses, causing increases in intracellular reactive oxygen species in the heart. Spinochrome D (SpD) has a structure of
