N normal phenotype
mortality/aging
• when treated in utero with doxycycline, mice die shortly after birth

cellular
• doxycycline-treated mouse embryonic fibroblasts arrest in S phase with increased DNA content compared with untreated cells
• doxycycline-treated mouse embryonic fibroblasts exhibit early cellular replicative senescence compared with untreated cells
• however, withdrawal of doxcycline restores proliferation

normal phenotype
• mice treated with doxycycline during adulthood exhibit no abnormal phenotype
