mortality/aging
postnatal lethality ( J:217463 )
• tamoxifen-treated mice die around 10 days of age probably from fulminant liver failure

liver/biliary system
liver hemorrhage ( J:217463 )
• tamoxifen-treated mice show dilated veins with intrahepatic bleeding
increased hepatocyte apoptosis ( J:217463 )
• Sirius Red staining, collapsed reticulin fibers, and increased ALT levels in tamoxifen-treated mice indicate that hepatocytes undergo massive apoptosis, leading to liver injury
liver inflammation ( J:217463 )
• tamoxifen-treated mice exhibit inflammatory cell infiltration in the liver
abnormal liver morphology ( J:217463 )
• tamoxifen-treated mice exhibit disruption of liver tissue architecture, presence of atypia, dilated veins with intrahepatic bleeding, signs of necrosis and inflammatory cell infiltration
hepatic necrosis ( J:217463 )
• in tamoxifen-treated mice

homeostasis/metabolism
increased circulating alanine transaminase level ( J:217463 )
• tamoxifen-treated mice show increased alanine transaminase (ALT) levels

cardiovascular system
liver hemorrhage ( J:217463 )
• tamoxifen-treated mice show dilated veins with intrahepatic bleeding

immune system
liver inflammation ( J:217463 )
• tamoxifen-treated mice exhibit inflammatory cell infiltration in the liver

cellular
increased hepatocyte apoptosis ( J:217463 )
• Sirius Red staining, collapsed reticulin fibers, and increased ALT levels in tamoxifen-treated mice indicate that hepatocytes undergo massive apoptosis, leading to liver injury

liver/biliary system
increased liver enzyme/coenzyme level ( J:217463 )
• NAD+ levels are increased in tamoxifen-treated livers

homeostasis/metabolism
increased liver enzyme/coenzyme level ( J:217463 )
• NAD+ levels are increased in tamoxifen-treated livers
decreased incidence of tumors by chemical induction ( J:217463 )
• tamoxifen-treated mice treated with diethylnitrosamine (DEN) do not show tumors at 24 weeks of age as seen in 60% of control mice and show normal alanine transaminase levels
decreased susceptibility to injury ( J:217463 )
• tamoxifien-treated mice supplied with a liver damage-inducing 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DCC)-supplemented diet present less liver damage and fibrosis

neoplasm
decreased incidence of tumors by chemical induction ( J:217463 )
• tamoxifen-treated mice treated with diethylnitrosamine (DEN) do not show tumors at 24 weeks of age as seen in 60% of control mice and show normal alanine transaminase levels
