neoplasm

increased mammary gland tumor incidence ( J:133578 )

• 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

integument

increased mammary gland tumor incidence ( J:133578 )

• removal of doxycycline results in apoptosis and reduced proliferation of tumors

• mice fed doxycycline develop tumors in all mammary glands within 10 weeks of induction, with a median latency between 6 and 8 weeks

• 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

endocrine/exocrine glands

increased mammary gland tumor incidence ( J:133578 )

• 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
