mortality/aging
premature death ( J:174842 )
• in beta-napthoflavone-treated mice

digestive/alimentary system
abnormal small intestinal crypt cell proliferation ( J:174842 )
• after 5 days, beta-napthoflavone-treated mice exhibit a loss of crypt width with loss of crypt stem cells and proliferating progenitors compared with control mice
• however, wild-type crypt stem cell escapers exhibit proliferation
decreased small intestinal villus size ( J:174842 )
• in beta-napthoflavone-treated mice
