Neurons rely on the release and subsequent cleavage of GSH to cysteinylglycine (CysGly) by astrocytes in order to maintain optimal intracellular GSH levels. In neurodegenerative diseases characterised by oxidative stress, neurons need an optimal GSH supply to defend themselves against free radicals
OBJECTIVE
Polydatin, a hydroxystilbene derived from the rhizome of Polygonum cuspidatum, elicits hepatoprotective and neuroprotective effects through its anti-oxidant properties. The present study aimed to determine the effects of oral administration of polydatin in alcoholic patients in order to
Polygonum cuspidatum has been used in traditional Chinese medicine to treat liver disorders associated with oxidative stress, inflammation and lipid accumulation for centuries in patients.The aim of this study was to examine whether P. cuspidatum extract Polygonum cuspidatum is widely used as food and medicine in Korea, China, and Japan. Its major bioactive components, resveratrol and emodin, reportedly protect against gastric lesions. We therefore aimed to investigate: (1) the gastroprotective effects of P. cuspidatum roots in
BACKGROUND
Polydatin and resveratrol are extractives of radix or rhizoma of Polygonum cuspidatum, and as the glycoside forms, it is a natural precursor of resveratrol.
OBJECTIVE
In this study, we aimed to explore the mutual transformation between polydatin and resveratrol in rats, and to compare the
Doxorubicin (DOX), is a highly active anticancer agent, but its clinical use is limited by its severe cardiotoxic side‑effects associated with increased oxidative stress and apoptosis. Resveratrol (RSVL) is a naturally occurring polyphenolic compound (trans-3,5,4'-trihydroxystilbene) found primarily
OBJECTIVE
Resveratrol (Res) which is a polyphenolic phytoalexin, has various biological properties. In the present study, we investigated whether Res extracted from Polygonum cuspidatum can reduce oxidative damage and cognitive impairment in senescence-accelerated mouse
Dry eyes are caused by highly increased osmolarity of tear film, inflammation, and apoptosis of the ocular surface. In this study, we investigated the effect of Polygonum cuspidatum (PCE) aqueous extract in in vivo and in vitro dry eye models. Dry eye was induced by excision of the lacrimal gland
Polydatin is one of main compounds in Polygonum cuspidatum, a plant with both medicinal and nutritional value. The possible hepatoprotective effects of polydatin on acute liver injury mice induced by carbon tetrachloride (CCl(4)) and the mechanisms involved were investigated. Intraperitoneal
Retinal ganglion cells (RGCs) death caused by oxidative stress is a common risk factor for glaucoma. In the present study, 8-hydroxycalamenene was isolated from the hexane fraction of Reynoutria elliptica. We showed that 8-hydroxycalamenene attenuated the cell death of transformed RGC-5 cells. This
Constitutive activation of the signal transducer and activator of transcription 3 (STAT3) or the nuclear factor-κB (NF-κB) pathway occurs frequently in cancer cells and contributes to oncogenesis. The activation of Janus kinase 2 (JAK2) and IκB kinase (IKK) are key events in STAT3 and NF-κB
