Sulfated polysaccharides enhance the biological activities of bone morphogenetic proteins.
Bone morphogenetic proteins (BMPs), which have been shown to be heparin-binding proteins, induce osteoblast differentiation in mesenchymal cells. In the present study, we examined the effects of heparin on the BMP activities in C2C12 myoblasts. Heparin dose dependently enhanced the osteoblast differentiation induced by not only homodimers of BMP-2 or BMP-4 but also heterodimers of BMP-2/6 or BM...
متن کاملFucans, but Not Fucomannoglucuronans, Determine the Biological Activities of Sulfated Polysaccharides from Laminaria saccharina Brown Seaweed
Sulfated polysaccharides from Laminaria saccharina (new name: Saccharina latissima) brown seaweed show promising activity for the treatment of inflammation, thrombosis, and cancer; yet the molecular mechanisms underlying these properties remain poorly understood. The aim of this work was to characterize, using in vitro and in vivo strategies, the anti-inflammatory, anti-coagulant, anti-angiogen...
متن کاملSulfated modification of the water-soluble polysaccharides from Polyporus albicans mycelia and its potential biological activities.
In this study, three chemically sulfated polysaccharides (SPAPs) were derived from one water-soluble polysaccharide (PAP) of Polyporus albicans mycelia by chlorosulfonic acid-pyridine method. The effects of polysaccharides on the immune function were examined after the mice were intragastrical administrated with polysaccharides at three doses of 100, 200, and 300 mg/kg body weight for 7 days. T...
متن کاملSignal transduction and biological functions of bone morphogenetic proteins.
Bone morphogenetic proteins (BMPs) are multi-functional growth factors and belong to the transforming growth factor beta (TGFbeta) superfamily. The roles of BMPs in embryonic development and cellular functions in postnatal animals have been extensively studied in recent years. Signal transduction studies have revealed that Smad1 and 5 are the immediate downstream molecules of BMP receptor and p...
متن کاملThe specificity of interactions between proteins and sulfated polysaccharides.
Sulfated polysaccharides are capable of binding with proteins at several levels of specificity. As highly acidic macromolecules, they can bind non-specifically to any basic patch on a protein surface at low ionic strength, and such interactions are not likely to be physiologically significant. On the other hand, several systems have been identified in which very specific substructures of sulfat...
