We investigated the effect of curcumin on insulin resistance and glucose homeostasis in male C57BL/KsJ-db/db mice and their age-matched lean non-diabetic db/+ mice. Both db/+ and db/db mice were fed with or without curcumin (0.02%, wt/wt) for 6 wks. Curcumin significantly lowered blood glucose and HbA 1c levels, and it suppressed body weight loss in db/db(More)
Celastrol has been reported to possess anticancer effects in various cancers; however, the precise mechanism underlying ROS-mediated mitochondria-dependent apoptotic cell death triggered by celastrol treatment in melanoma cells remains unknown. We showed that celastrol effectively induced apoptotic cell death and inhibited tumor growth using tissue culture(More)
BACKGROUND/OBJECTIVES Inflammation is associated with various types of acute and chronic alcohol liver diseases. In this study, we examined whether umbelliferone (7-hydroxycoumarin, UF) ameliorates chronic alcohol-induced liver damage by modulating inflammatory response and the antioxidant system. METHODS Rats were fed a Liber-Decarli liquid diet(More)
The anti-inflammatory mechanism of 5-hydroxy-3,6,7,8,3',4'-hexamethoxyflavone (5HHMF), a polyhydroxyflavone isolated from the marine algae Hizikia fusiforme, was investigated in RAW 264.7 murine macrophage cells. Western blot and reverse transcriptase PCR analyses indicated that adding 5HHMF to cultured cells significantly reduced the production of nitric(More)
