Astaxanthin (AST) is a carotenoid pigment which possesses potent antioxidative, anti-inflammatory, and neuroprotective properties. The aim of this study was to investigate whether administration of AST had protective effects on D-galactose-induced brain aging in rats, and further examined its protective mechanisms. The results showed that AST treatment(More)
SCOPE In this study, the effects of lutein on neuroinflammation in lipopolysaccharide (LPS)-activated BV-2 microglia were investigated. METHODS AND RESULTS The production of proinflammatory cytokines tumor necrosis factor-α, interleukin-1β, and nitric oxide was measured in culture medium using enzyme immunoassay and Griess reagent, respectively. The(More)
Isoorientin (ISO) (CAS RN: 4261-42-1) is a flavonoid compound that can be extracted from several plant species, such as Phyllostachys pubescens, Patrinia, and Drosophyllum lusitanicum. ISO is able to induce apoptosis through mitochondrial dysfunction and inhibition of PI3K/Akt signaling pathway in HepG2 cells, however, the effects of ISO on MAPK signaling(More)
Momordin Ic is a principal saponin constituent of Fructus Kochiae, which acts as an edible and pharmaceutical product more than 2000 years in China. Our previous research found momordin Ic induced apoptosis by PI3K/Akt and MAPK signaling pathways in HepG2 cells. While the role of autophagy in momordin Ic induced cell death has not been discussed, and the(More)
Acrylamide (ACR), a potent neurotoxin, can be produced during food processing at high temperature. This study examined the redox-dependent apoptotic and inflammatory responses of ACR in an immortalized mouse microglia cell line BV2. The exposure of BV2 cells to ACR reduced cell viability and induced apoptosis in a concentration-dependent manner. ACR(More)
The study investigated the protective effects of carnosic acid (CA), the principal constituent of rosemary, on lipopolysaccharide (LPS)-induced oxidative/nitrosative stress and hepatotoxicity in rats. CA was administered orally to rats at doses of 15, 30 and 60 mg/kg body weight before LPS challenge (single intraperitoneal injection, 1 mg/kg body weight).(More)
Isoorientin (ISO) is considered one of the most important flavonoid-like compounds responsible for health benefits, including the prevention of liver damage as well as antioxidant, anti-inflammatory, and anti-nociceptive activities. Our previous study showed that ISO inhibited the proliferation of hepatoma cells through increasing intracellular ROS levels.(More)
Chicoric acid has recently become a hot research topic due to its potent bioactivities. However, there are few studies relevant to this acid's pharmacokinetic characteristics and the pharmacological activities of its metabolites. To compare the abilities of chicoric acid and its metabolites in scavenging free radicals and their effects on the viability of(More)
