neoplasm
• mice fed doxycycline develop tumors in all mammary glands within 10 weeks of induction, with a median latency between 6 and 8 weeks
• removal of doxycycline results in apoptosis and reduced proliferation of tumors
• after doxycycline withdrawal, tumors become smaller within 5-7 days of withdrawal, however, none of the palpable tumors regress completely after 3 weeks and begin to regrow within 3-6 weeks

vision/eye
• moderate retinal atrophy characterized by loss of the outer layers (rods and cones, outer nuclear layer, and outer plexiform layer)

neoplasm
• males and females develop mammary tumors
• tumor latency is inversely correlated with generation number, with tumor latency for F1 females being 8 months and 5 months for F3 females
• mice develop multiple, distinct tumors, with an average tumor burden of 5 tumors per mouse
• tumors are adenocarcinomas
• treatment with the FPTase inhibitor L-744,832 results in inhibition of tumor growth
• metastases to the lung are occasionally seen
