A linear sulfated fucan with a regular repeating sequence of [3)-alpha-L-Fucp-(2SO4)-(1-->3)-alpha-L-Fucp-(4SO4)-(1-->3)-alpha-L-Fucp-(2,4SO4)-(1-->3)-alpha-L-Fucp-(2SO4)-(1-->]n is an anticoagulant polysaccharide mainly due to thrombin inhibition mediated by heparin cofactor II. No specific enzymatic or chemical method is available for the preparation of(More)
Brain-specific chondroitin sulfate (CS) proteoglycan (PG) DSD-1-PG/6B4-PG/phosphacan isolated from neonatal mouse brains exhibits neurite outgrowth-promoting activity toward embryonic rat and mouse hippocampal neurons in vitro through the so-called DSD-1 epitope embedded in its glycosaminoglycan side chains. Oversulfated CS variants, CS-D from shark(More)
Oversulfated chondroitin sulfate (CS), dermatan sulfate (DS), and CS/DS hybrid structures bind growth factors, promote the neurite outgrowth of hippocampal neurons in vitro, and have been implicated in the development of the brain. To investigate the expression of functional oversulfated DS structures in the brain, a novel monoclonal antibody (mAb), 2A12,(More)
Proper brain neuronal circuitry formation and synapse development is dependent on specific cues, either genetic or epigenetic, provided by the surrounding neural environment. Within these signals, thyroid hormones (T3 and T4) play crucial role in several steps of brain morphogenesis including proliferation of progenitor cells, neuronal differentiation,(More)
BACKGROUND Heparin exerts beneficial effects in different experimental models of nephropathy, as observed by the preservation of the structural morphology of the kidney after heparin therapy. Here we investigate molecular and cellular events involved in the protective effects of heparin in the progression of renal disease after unilateral ureteral(More)
Heparin cofactor II (HCII) is a plasma protein that inhibits thrombin rapidly in the presence of dermatan sulfate or hepa-rin. We previously reported that the time to thrombotic occlusion of the carotid artery after photochemical injury was shorter in HCII-deficient mice than in wild-type control animals. In this paper, we describe the antithrombotic(More)
BACKGROUND Previously, we have reported the presence of highly sulfated dermatans in solitary ascidians from the orders Phlebobranchia (Phallusia nigra) and Stolidobranchia (Halocynthia pyriformis and Styela plicata). Despite the identical disaccharide backbone, consisting of [→4IdoA(2S)β-1→3GalNAcβ-1→], those polymers differ in the position of sulfation on(More)
Dermatan sulfates and heparin, similar to the mammalian glycosaminoglycans, but with differences in the degree and position of sulfation were previously isolated from the body of the ascidian Styela plicata and Ascidia nigra. These differences produce profound effects on their anticoagulant properties. S. plicata dermatan sulfate composed by 2-O-sulfated(More)
Correction: Dermatan sulfate in tunicate phylogeny: Order-specific sulfation pattern and the effect of [®4IdoA(2-Sulfate)b-1®3GalNAc (4-Sulfate)b-1®] motifs in dermatan sulfate on heparin cofactor II activity Abstract After the publication of the work entitled " Dermatan sulfate in tunicate phylogeny: Order-specific sulfation pattern and the effect of(More)
