To investigate the protective effects of acteoside against apoptosis induced by X-ray radiation in human skin fibroblasts (HSFs), the cells were divided into the following groups: Control group; X-ray radiation group; acteoside group, in which the confluent cells were preincubated with 50 μg/ml acteoside for 2 h followed by radiation; and positive control group, in which the cells were preincub...

Numerous studies have reported that inflammatory cytokines are important mediators for osteoclastogenesis, thereby causing excessive bone resorption and osteoporosis. Acteoside, the main active compound of Rehmannia glutinosa, which is used widely in traditional Oriental medicine, has anti-inflammatory and antioxidant potentials. In this study, we found that acteoside markedly inhibited osteocl...

Parkinson's disease (PD) is characterized by the progressive degeneration of the dopaminergic neurons in the substantia nigra (SN) region. Acteoside has displayed multiple biological functions. Its potential role against PD and the underlying signaling mechanisms are largely unknown. Here, we showed that oral administration of acteoside significantly attenuated parkinsonism symptoms in rotenone...

Acteoside (verbascoside) is extensively distributed in Abeliophyllum distichum and has antimicrobial and anti-inflammatory properties. Thymic stromal lymphopoietin (TSLP) has a pivotal function in the pathogeneses of inflammatory diseases through increasing the mast cell proliferation via the activation of murine double minute 2 (MDM2). Here, we investigate whether acteoside attenuates the MDM2...

Acteoside and isoacteoside, two phenylethanoid glycosides, coexist in some plants. This study investigates the memory-improving and cytoprotective effects of acteoside and isoacteoside in amyloid β peptide 1-42 (Aβ 1-42)-infused rats and Aβ 1-42-treated SH-SY5Y cells. It further elucidates the role of amyloid cascade and central neuronal function in these effects. Acteoside and isoacteoside ame...

We investigated the in vitro effects of acteoside on the proliferation, cell cycle regulation and differentiation of HL-60 human promyelocytic leukemia cells. Acteoside inhibited the proliferation of HL-60 cells in a concentration- and time-dependent manner with an IC50, approximately 30 microM. DNA flow cytometric analysis indicated that acteoside blocked cell cycle progression at the G1 phase...

This study investigated the role of acteoside in the amelioration of mucositis. C57BL/6 mice were gavaged daily with acteoside 600 μg for 5 d prior to induction of mucositis and throughout the experimental period. Mucositis was induced by methotrexate (MTX; 12.5 mg/kg; s.c.). Mice were culled on d 5 and d 11 after MTX. The duodenum, jejunum, and ileum were collected for myeloperoxidase (MPO) ac...

The immediate-type allergic reaction is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. In this study, we investigated the effect of acteoside extracted from CISTANCHE TUBULOSA (Schrenk) R. Wight on the basophilic cell-mediated allergic reaction. The effect of acteoside on β-hexosaminidase release and intracellular [Ca (2+)] I level from rat basophilic leuke...

A simple and sensitive liquid chromatography with amperometric detection was developed for the first time to monitor the protein-unbound acteoside in the rat blood and brain microdialysate by microdialysis technique. Microdialysis samples without further cleanup procedures were directly injected into the HPLC and separated using a reversed-phase C18 column (150 mmx2 mm, i.d. 5 microm) maintaine...

characterized by irreversible, progressive loss of memory followed by complete dementia. Cognitive impairment in AD is caused mainly by death of cholinergic neurons in basal forebrain area, though other neurotransmitter systems could well be involved. A deficit of acetylcholine (ACh) in an AD brain is well known. At the same time, extent of dementia correlates well with the extent of neuronal d...
