mortality/aging

premature death ( J:161780 )

• mice treated tamoxifen at weaning exhibit an increase in lifespan of 8 weeks (42 weeks) compared with similarly treated Kras^tm1Bbd/Kras⁺ Polr2a^{tm1(cre/ERT2)Bbd}/Polr2a^{tm1(cre/ERT2)Bbd} littermates (34 weeks)

neoplasm

decreased tumor incidence ( J:161780 )

• tamoxifen-treated mice exhibit reduced tumor burden compared with similarly treated Kras^tm1Bbd/Kras⁺ Polr2a^{tm1(cre/ERT2)Bbd}/Polr2a^{tm1(cre/ERT2)Bbd} mice
