Application


  • Superoxide dismutase activity as a measure of hepatic oxidative stress in cattle following ethionine administration.: This study evaluates the hepatic oxidative stress in cattle induced by ethionine administration by measuring superoxide dismutase activity. The findings suggest a significant oxidative response, highlighting the role of DL-Ethionine in studying liver oxidative mechanisms (Abd Ellah et al., 2009).

Biochem/physiol Actions

DL-Ethionine is a racemic mixture of the anti-methylation agent L-Ethionine and its enantiomer D-Ethionine. DL-Ethionine is used as a dietary supplement to accelerate cholangiocarcinogenesis in vivo. DL-Ethionine is used to induce oxidative stress in liver to study the levels and activities of anti-oxidative enzymes and compounds such as glutathione.

Cells with slow proliferation kinetics that retain the nuclear label over long time periods-the label-retaining cells (LRCs)-represent multipotent stem cells in a number of adult tissues. Since the identity of liver LRCs (LLRCs) had remained elusive we utilized a genetic

To evaluate an involvement of LKB1 gene alteration during pancreatic carcinogenesis, mutations in the LKB1 gene in hamster pancreatic duct adenocarcinomas (PDAs) induced by N-nitrosobis(2-oxopropyl)amine (BOP) were investigated. Female Syrian golden hamsters received 30 mg/kg of BOP followed by repeated

Intrahepatic cholangiocarcinoma (ICC) incidence and mortality are increasing in the United States and worldwide. ICC etiologies involve chronic inflammation. We hypothesize that the nonsteroidal anti-inflammatory agent sulindac may prevent ICC by targeting cyclooxygenase-1 and -2 (COX-1, -2) as well as
