Zonation of metabolic activities within specific structures and cell types is a phenomenon of liver organization and ensures complementarity of variant liver functions like protein production, glucose homeostasis and detoxification. To analyze damage and regeneration of liver tissue in response to a toxic agent, expression of liver specific enzymes was analyzed by in situ hybridization in mouse...

Norcantharidin (NCTD) is the demethylated form of cantharidin, which is the active substance of mylabris. To examine the pathway of NCTD-induced A375-S2 cell death, 3-(4, 5-dimethylthiazol-2-yl)-2, 5-dipheyltetrazolium bromide (MTT) assay, photomicroscopical observation, DNA agarose gel electrophoresis, caspase activity assay and Western blot analysis were carried out. A375-S2 cells treated wit...

Microsomal delta 7-sterol 5-desaturase of cholesterol biosynthesis is a multienzyme system which catalyzes the introduction of the delta 5-bond into delta 7-cholestenol to form 7-dehydrocholesterol. The detergent-solubilized 5-desaturase has been purified more than 70-fold and resolved from electron carriers and other rat liver microsomal enzymes of sterol biosynthesis by chromatography on DEAE...
