The purpose of this study is to investigate the protective effect and molecular mechanism of the sulfated polysaccharide (SJP) isolated from the sea cucumber Stichopus japonicus against 6-OHDA-induced toxicity in SH-SY5Y cells. The results showed that SJP could protect SH-SY5Y cells against 6-OHDA-induced cell injury. We found that SJP effectively improves(More)
Stichopus japonicus Polysaccharide (SJP) is a sulfated polysaccharide from the body wall of the sea cucumber, Stichopus japonicus. Fucoidan is a heparinoid compound that belongs to a family of sulfated polyfucose polysaccharides. Heparin is a glycosaminoglycan. SJP, fucoidan, and heparin profoundly promoted stromal cell-derived factor 1 alpha(More)
Horny Goat Weed is a commonly used in Chinese herbal medicine. And it is used in multiple kinds of diseases including cardiovascular diseases. Icariin is the major component isolated from Horny Goat Weed. It is reported to have lipid-lowering effect. In atherosclerosis, icariin attenuate the enhanced prothrombotic state independently of its lipid-lowering(More)
Neural stem/progenitor cells (NSPCs) exhibit therapeutic potential in neuronal diseases. Previously, we reported that a sulfated polysaccharide (HS) from the sea cucumber Stichopus japonicus increased the proliferation of NSPCs. Since the formation of neurospheres is related with NSPCs proliferation, we investigated the mechanism leading to neurosphere(More)
AIM Medicinal leech has been widely used as a traditional Chinese medicine in cardiovascular diseases. However, its pharmaceutical effect is not fully revealed. The goal of this study was to determine whether a leech extract has the effect of anti-atherosclerosis in ApoE −/− mice and the mechanism of this effect. METHODS AND RESULTS In vivo experiments:(More)
The present study describes a positive regulatory loop between SJP and the SDF-1α/CXCR4 axis in NSC migration. The treatment of NSCs with SJP and SDF-1α increases the cell migration capacity and promotes cell migration from the neurospheres. These effects are accompanied by the up-regulation of Nestin, N-cadherin, TLR4, TNF-α, Cyclin D1, EGFR, Alpha 6(More)
To test the effects of a sulfated polysaccharide, Haishen (HS) on the viability and proliferation of neural stem/progenitor cells (NSPCs), we isolated the polysaccharide from the body wall of the sea cucumber Stichopus japonicus by enzymolysis extraction, anion-exchange and gel-permeation chromatography. HS is a highly sulfated fucoidan with a molecular(More)
In this report, we demonstrate that the sulfated polysaccharide, Haishen (HS), which was isolated from the body wall of the sea cucumber Stichopus japonicus can induce morphological transformation and proliferation of astrocytes in vitro when combined with basic fibroblast growth factor 2 (FGF-2). Cell morphology showed no change when induced by HS or FGF-2(More)
Eupolyphaga sinensis Walker is an important insect used in Chinese traditional medicine. In this study, we purified a 72-kDa anticancer protein, designated as EPS72, from this species using ammonium sulfate precipitation, ultrafiltration, CM Sepharose Fast Flow cation exchange, Q Sepharose High Performance (HP) anion exchange, Butyl Sepharose HP hydrophobic(More)
