Role of CYP2E1 in diethylnitrosamine-induced hepatocarcinogenesis in vivo.
CYP2E1 metabolizes many low-molecular weight toxins and carcinogens. Some in vitro experiments suggest that CYP2E1 may be involved in the metabolic activation of diethylnitrosamine. However, there has been no direct evidence demonstrating a role for CYP2E1 in diethylnitrosamine-mediated carcinogenesis in vivo. To clarify this, we carried out a diethylnitrosamine-induced hepatocarcinogenesis exp...
متن کاملHigh CYP2E1 activity correlates with hepatofibrogenesis induced by nitrosamines
Hepatofibrosis, which leads to cirrhosis and eventual hepatocellular carcinoma, is a common response to chronic toxin-mediated liver injury. Nitrosamines are potent hepatotoxic agents that cause necrosis and subsequent fibrosis in the liver as a result of cytochrome P450 2E1 (CYP2E1)-dependent metabolism, which generates toxic metabolites that form adducts with nucleic acids, leading to hepatot...
متن کاملPreventive Effect of Geraniol on Diethylnitrosamine-Induced Hepatocarcinogenesis in Rats
BACKGROUND Geraniol is a plant-derived phytochemical possessing anti-cancer action. The anti-carcinogenic effect of geraniol was investigated in the diethylnitrosamine (DEN)-induced hepatocarcinogenic rat model. METHODS Male Wistar rats were intraperitoneally injected with 300 μL of phosphate-buffered saline (PBS) (G1; n = 4) or DEN (100 mg/kg body weight) dissolved in PBS (G2; n = 8) every 2...
متن کاملCurcumin-containing diet inhibits diethylnitrosamine-induced murine hepatocarcinogenesis.
Curcumin has been widely used as a spice and coloring agent in foods. Recently, curcumin was found to possess chemopreventive effects against skin cancer, forestomach cancer, colon cancer and oral cancer in mice. Clinical trials of curcumin for prevention of human cancers are currently ongoing. In this study, we examine the chemopreventive effect of curcumin on murine hepatocarcinogenesis. C3H/...
متن کاملRole of the BrafV637E mutation in hepatocarcinogenesis induced by treatment with diethylnitrosamine in neonatal B6C3F1 mice
The BrafV637E mutation is frequently reported in mouse hepatic tumors, depending on the mouse strain, and corresponds to the human BrafV600E mutation. In this study, we detected the BrafV637E mutation by whole-exome analysis in 4/4 hepatic tumors induced by neonatal treatment with diethylnitrosamine (DEN) in male B6C3F1 mice. We also detected the BrafV637E mutation in 54/63 (85.7%) hepatic lesi...
