The structure of amplified 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) DNA of carrot suspension-cultured cell lines selected for glyphosate resistance was analyzed to determine the mechanism of gene amplification in this plant system. Southern hybridization of the amplified DNA digested with several restriction enzymes probed with a petunia EPSPS(More)
Citreoviridin is a toxic metabolite from fungus that has been shown to be an inhibitor of mitochondrial F1-ATPases. Studies of citreoviridin, however, have been compromised by the light-dependent isomerization that it undergoes. The isomerization is a potential source of extensive variability in the studies, if citreoviridin and isocitreoviridin have(More)
Non-alcoholic fatty liver disease is associated with inhibited AMP-activated kinase (AMPK) and activation of sterol regulatory element binding protein 1 (SREBP-1). AMPK phosphorylation inhibits SREBP-1, a major transcription factor of de novo lipogenesis, by inhibiting the liver X receptor (LXR) or by direct phosphorylation. Resveratrol, a polyphenol, has(More)
Herbal medicines are widely used in many countries for the treatment of many diseases. Although the use of herb extracts as alternative medicine is growing, their toxicological properties have not been thoroughly investigated. In this study, we have investigated the effects of water and ethanol extracts of 18 herbs on the hepatic lipid metabolism and(More)
Human cadmium (Cd) exposure is associated with cancers of the lung and kidney. Using cDNA microarray analysis, we have recently reported that the expression of E2F1 is reduced by Cd in human lung fibroblasts, indicating the possibility of G1-phase arrest. To test this hypothesis, we investigated the effects of Cd on the cyclin-dependent kinase (CDK2) and(More)
