N normal phenotype
neoplasm
• doxycycline-treated mice develop more macro- and microadenomas in the small intestinal and, to a lesser extent colon, compared with Apcmin heterozygotes
• doxycycline-treated mice develop more macro- and microadenomas in the small intestinal and, to a lesser extent colon, compared with Apcmin heterozygotes
• doxycycline-treated mice exhibit increased size of microadenomas compared with Apcmin heterozygotes

cellular
• doxycycline-treated mice exhibit loss of imprinting and increased expression of Igf2 compared with control mice
• doxycycline-treated mice exhibit biallelic methylation of H19 differentially methylated region in tumors and normal colon epithelial cells compared with control mice
• doxycycline-treated mice exhibit hypermethylation of Sfrp2, Sfrp4 and Sfrp5 in tumors and normal colon epithelial cells unlike control mice
• however, mice exhibit normal methylation of of Snrpn differentially methylated region in tumors and normal colon epithelial cells, and global DNA methylation

digestive/alimentary system
• doxycycline-treated mice develop more macro- and microadenomas in the small intestinal and, to a lesser extent colon, compared with Apcmin heterozygotes
