|Echinacoside ameliorates D-galactosamine plus lipopolysaccharide-induced acute liver injury in mice via inhibition of apoptosis and inflammation.[Pubmed: 24797709]|
|OBJECTIVE: This study aimed to investigate the protective effects of Echinacoside, one of the phenylethanoids isolated from the stems of Cistanche salsa, a Chinese herbal medicine, on D-galactosamine (GalN) and lipopolysaccharide (LPS)-induced acute liver injury in mice. Pretreatment with Echinacoside remarkably improved the survival rate of GalN/LPS-treated mice and attenuated acute hepatotoxicity, as demonstrated by decreased ALT levels and improved histological signs. Echinacoside shows both anti-apoptotic and anti-inflammatory properties, characterized by a substantial inhibition of hepatocyte apoptosis and a significant reduction in the inflammatory markers, including myeloperoxidase, extracellular nucleosomes, high-mobility group box 1, and inflammatory cytokines in the plasma of mice, which may be important mechanisms related to its protective effect. CONCLUSION: Our results suggest that Echinacoside can provide a pronounced protection against GalN/LPS-induced acute liver injury in mice, which may complement the available strategies for management of acute liver damage in clinical settings.|

|Echinacoside Protects against 6-Hydroxydopamine-Induced Mitochondrial Dysfunction and Inflammatory Responses in PC12 Cells via Reducing ROS Production.[Pubmed: 25788961]|
|Echinacoside (ECH) is a phenylethanoid glycoside isolated from the stems of Cistanche salsa, showing a variety of neuroprotective effects in previous studies. The present study was to investigate its effect against 6-OHDA-induced neurotoxicity and possible mechanisms in PC12 cells. The results showed that 6-OHDA reduced cell viability, decreased oxidation-reduction activity, decreased mitochondrial membrane potential, and induced mitochondria-mediated apoptosis compared with untreated PC12 cells. However, Echinacoside treatment significantly attenuated these changes induced by 6-OHDA. In addition, Echinacoside also could significantly alleviate the inflammatory responses induced by 6-OHDA. Further research showed that Echinacoside could reduce 6-OHDA-induced ROS production in PC12 cells. These results suggest that the underlying mechanism of Echinacoside against 6-OHDA-induced neurotoxicity may be involve in attenuating mitochondrial dysfunction and inflammatory responses by reducing ROS production.|

|Echinacoside improves hematopoietic function in 5-FU-induced myelosuppression mice.[Pubmed: 25623854]|
|AIMS: We aimed to investigate the effects of Echinacoside (ECH) on hematopoietic function in 5-FU-induced bone marrow depression mice. MAIN METHODS: In vitro, after stimulation with Echinacoside, the proliferation ability of bone marrow (BM) cells and bone marrow stromal cells (BMSCs) derived from myelosuppression mice were assessed by CCK8 assay and morphology, respectively. In vivo, 5-FU-induced myelosuppression or control mice were intragastrically administrated with either Echinacoside at 15 mg/kg or the equal volume of normal saline daily for 12 days before BM cells were isolated for colony-forming cell assay. Meanwhile, BMSCs were cultured for 4 weeks before cells were observed for growth pattern, cell culture supernatants were collected for GM-CSF secretion by ELISA, and RNA of the cells were extracted for EPO and GM-CSF RT-PCR. BM cells or BMSCs stimulated with Echinacoside for 24 h or 48 h were collected for protein extraction and Western blotting. KEY FINDINGS: Echinacoside stimulated the growth of BM cells but not BMSCs derived from 5-FU treated mice. The intragastric administration of Echinacoside in 5-FU treated mice could increase the number of total hematopoietic progenitor cells and GM progenitor cells to healthy control mice level, but not BFU progenitor cells. BMSCs from Echinacoside treated myelosuppression mice grew more vigorously and expressed more GM-CSF, but not EPO. Echinacoside activated the PI3K signaling pathway in 5-FU suppressed BM cells. SIGNIFICANCE: Echinacoside could improve the hematopoietic function of bone marrow in 5-FU-induced myelosuppression mice. Echinacoside can be considered as an alternative effective therapy for patients during chemotherapy or HSC transplantation.|

|Transient exposure to echinacoside is sufficient to activate Trk signaling and protect neuronal cells from rotenone.[Pubmed: 23189969]|
|We reported that Echinacoside, a small natural compound, elicits neuroprotection by activating Trk receptors and their downstream signal pathways. Echinacoside is the major active component of Cistanches Herba, a widely used Chinese herb with neuroprotective effects. We showed in this study that transient exposure to Echinacoside is sufficient to protect neuronal cells and non-neuronal cells over-expressed with TrkA or TrkB against rotenone injury. Additional investigations on the mechanisms underlying suggested that transient treatment with Echinacoside inhibits cytochrome c release and caspase-3 activation caused by ensuing rotenone exposure via activating Trk-extracellular signal-regulated kinase (ERK) pathway in neuronal cells. As Echinacoside is able to cross the blood-brain barrier freely, it may have a promising potential in neurodegenerative diseases treatment.|

|Echinacoside inhibits amyloid fibrillization of HEWL and protects against Aβ-induced neurotoxicity.[Pubmed: 25193102]|
|We investigated the protection provided by Echinacoside against neurotoxicity induced by β-amyloid protein (Aβ). Through spectroscopic analyses, electron microscopy, cell viability assay, and hemolysis assay, we found that Echinacoside dose dependently inhibited HEWL aggregation, and this inhibition occurred in different fiber-forming stages. Echinacoside could also scavenge the DPPH and OH free radicals in a concentration-dependent manner. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and 2',7'-dichlorodihydrofluoresceindiacetate (DCFH-DA) fluorescent measurement results indicated that Echinacoside could increase viability of rat pheochromocytoma PC12 cells injured by Aβ and suppress the increase in intracellular reactive oxygen species (ROS) triggered by Aβ. The present study findings facilitate a better understanding of the interaction between Echinacoside and amyloid-forming proteins and also shed light on the protection of Echinacoside against amyloid fibril-induced neuronal cell death.|
