Human milk mucin inhibits rotavirus replication and prevents experimental gastroenteritis.
Acute gastrointestinal infections due to rotaviruses and other enteric pathogens are major causes of morbidity and mortality in infants and young children throughout the world. Breast-feeding can reduce the rate of serious gastroenteritis in infants; however, the degrees of protection offered against rotavirus infection vary in different populations. The mechanisms associated with milk-mediated...
متن کاملGambogic acid inhibits LPS-induced macrophage pro-inflammatory cytokine production mainly through suppression of the p38 pathway
Objective(s): In traditional Chinese medicine, gamboge can detoxify bodies, kill parasites, and act as a hemostatic agent. Recent studies have demonstrated that gambogic acid (GBA) suppressed inflammation in arthritis, and also presented antitumor effect. Thus, this study investigated the new biological properties of GBA on macrophages.Materials and Methods: RAW 264.7 cells were pretreated with...
متن کاملEffect of 6-Thioguanine and Methyl-6-Thioguanine on stability of DNA duplexes
6-Thioguanine (isG) has been used for the past thirty years as an anti-cancer agent in maintenance chemotherapy for childhood acute lymphoblastic leukemia as well as acute myeloid leukemia. Despite its long-standing clinical use, little is understood of the molecular basis of the cytotoxicity associated with 6SG. Research has shown that 6SG is incorporated into DNA during replication after whic...
متن کاملIn vitro replication and thermodynamic studies of methylation and oxidation modifications of 6-thioguanine
The cytotoxic effects of thiopurine drugs are mostly exerted through the formation of thioguanine nucleotide and its subsequent incorporation into DNA. The 6-thioguanine (6-TG) in DNA can be converted to S6-methylthio-2-aminopurine (2-AP-6-SCH3) and 2-aminopurine-6-sulfonic acid (2-AP-6-SO3H) upon reaction with S-adenosyl-L-methionine and irradiation with UVA light, respectively. Here we prepar...
متن کاملScheduling of arabinosylcytosine and 6-thioguanine therapy.
SUMMARY Mice treated simultaneously with 1-0-D-arabinofuranosyl-cytosine (ara-C) and 6-thioguanine (6-TG) were protected from the lethal effects of 6-TG. No protection was afforded if ara-C was given 16 hr before the 6-TG. DNA synthesis in mouse bone marrow was immediately depressed to 3 to 12% of that of control in various experiments, after treatment with ara-C, 10 to 20 mg/kg; it then reboun...
