mortality/aging
• in BBN treated mice median survival time is 217 days and maximum survival time is 237 days, while only 1 wild-type mouse died at 177 days

neoplasm
• increased volume and total tumor burden in an N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN, 0.05% in water for 18 weeks) model of induced bladder cancer
• in BBN induced bladder tumors, tumor cells are more condensed and have larger nuclei

homeostasis/metabolism
• in males but not females
