In an attempt to magnify differences in the immune responses of potentially immunosuppressed cancer patients and normal controls, an assessment was made on the effects of the competitive inhibitor alpha-methyl-D-mannoside on the concanavalin A (Con A)-induced blastogenic responses of lymphocytes
Pentagamaboronon-0 (PGB-0), a curcumin analog compound, has been synthesized as a candidate of boron-carrier pharmaceutical (BCP) for boron neutron capture therapy (BNCT); however, this compound is poorly soluble in water. To improve its solubility, aqueous formulations of PGB-0 with a
BACKGROUND
Combination of platinum derivatives with paclitaxel is currently the standard front line regimen for patients with epithelial ovarian carcinoma, and represents also an active regimen in patients with metastatic breast or unknown primary carcinomas. Measurement of intestinal permeability
The expression of complex carbohydrates recognised by Helix pomatia lectin (HPA, nominal monosaccharide binding specificity alpha-GalNAc) has been shown to predict unfavourable prognosis in breast and other cancers. It has been suggested that the prognostic significance of HPA binding may be through
Glycosylation of proteins plays multiple roles in cell-cell and cell-matrix interactions. Fucose is a monosaccharide associated with glycosylation events and is known to be over-expressed in many malignant tumors. By using alpha-L-fucosidase (alpha-L-fase), a glycosidase that specifically removes
An extensive family of UDP-N-alpha-d-galactosamine: polypeptide N-acetylgalactosaminyltransferases (polypeptide N-acetylgalactosaminyltransferases, ppGalNAc-T's) catalyse the attachment of the first N-acetylgalactosamine (GalNAc) monosaccharide to the polypeptide at the initiation of O-linked
Microsomal preparations from malignant human breast tumors catalyzed the transfer of mannose and glucose from GDP-[14C]-Man and UDP-[14C]-Glc into lipid-linked sugars and glycoprotein-like substances. As judged by several criteria the obtained lipid-linked monosaccharides behaved as dolichyl
Glycosylation drives critical processes important for mammalian cell-cell and cell-matrix interactions. Alpha-L-fucose (alpha-L-f) is a key monosaccharide component of oligosaccharides that has been found to be overexpressed during tumor progression. Modification of cell surface fucosylation, we
The specificity characteristics of transporters can be exploited for the development of novel diagnostic therapeutic probes. The facilitated hexose transporter family (GLUTs) has a distinct set of preferences for monosaccharide substrates, and while some are expressed ubiquitously (e.g., GLUT1),
Glycopeptide-preferring polypeptide N-acetylgalactosamine transferase (ppGalNAc‑T) is a key enzyme that initiates the formation of the first GalNAc monosaccharide to polypeptides at Thr/Ser residues by O‑linked glycosylation. In order to investigate the effects of ppGalNAc‑T1 and ppGalNAc‑T2 on the
Ethnopharmacological relevance: The rhizome of Anemone raddeana Regel (A. raddeana) is a famous traditional Chinese medicine (TCM) recorded in Chinese Pharmacopoeia for the treatment of carbuncle and swelling. Carbuncle swollen is an explanation of tumor in the
Breast cancer is the second cause of cancer-related death among Women. Current therapies for breast cancer have adverse side-effects. Selenium (Se)-containing polysaccharides have multiple health benefits to humans. Pyracantha fortuneana (P. fortuneana) contains rich Se polysaccharides. We
Abnormal cell surface display of sialic acids - a family of unusual 9-carbon sugars - is widely recognized as distinguishing feature of many types of cancer. Sialoglycans, however, typically cannot be identified with sufficiently high reproducibility and sensitivity to serve as clinically accepted
In many human carcinomas, mucin-1 (MUC1) is overexpressed and aberrantly glycosylated, resulting in the exposure of previously hidden antigens. This generates new patient antibody profiles that can be used in cancer diagnosis. In the present study, we focused on the MUC1 associated Tn antigen
In the present paper we report evidence about the formation of polyprenyl-phosphate monosaccharides, their elongation products and the assembly of dolichyl-diphosphate-oligosaccharide to endogenous T47D clone 11 proteins upon incubation with [14C]glucose. The influence of estradiol and two
