Synthesis and Sulfation of Branched Dextrans [PDF]

open access: yesPolymer Journal, 1990
2,4-Di-O-benzyl-(1→6)-α-d-glucopyranan, which was synthesized by ring-opening polymerization of 1,6-anhydro-2,4-di-O-benzyl-3-O-tert-butyldimethylsilyl-β-d-glucopy-ranose and subsequent desilylation, was β-glucosylated or α-mannosylated by the orthoester method. Deprotection of glycosylated polysaccharides with sodium in liquid ammonia was performed to

Rho-A prenylation and signaling link epithelial homeostasis to intestinal inflammation [PDF]

open access: yes, 2016
Although defects in intestinal barrier function are discussed as a key pathogenic factor in patients with inflammatory bowel diseases (IBD), the molecular pathways driving disease-specific alterations of intestinal epithelial cells (IECs) are largely ...

Transport of Dextran Sulfates to Rat Livers

open access: yesJapanese Journal of Pharmacology, 1979
Liver subcellular distributions of three different dextran sulfates (DSs) with average molecular weight (AMW) of 3000, 20,000, and 200,000, and sulfur content of 18%, anticoagulants and antilipemic agents, were examined in rats after intravenous administration of 50 mg/kg.

Phosphomannosyl receptors may participate in the adhesive interaction between lymphocytes and high endothelial venules. [PDF]

open access: yes, 1984
Normal and malignant lymphocytes can migrate from the bloodstream into lymph nodes and Peyer's patches. This process helps distribute normal lymphocytes throughout the lymphoid system and may provide a portal of entry for circulating malignant cells.

Evidence for the role of proteoglycans in cation-mediated gene transfer [PDF]

open access: yes, 1996
We report evidence that gene complexes, consisting of polycations and plasmid DNA enter cells via binding to membrane-associated proteoglycans. Treatment of HeLa cells with sodium chlorate, a potent inhibitor of proteoglycan sulfation, reduced luciferase
