Research Abstract

Mouse APOBEC3, a host factor that restricts the replication of exogenous retrovirus, is abundantly expressed in virus-resistant C57BL/6 (B6) mice. We have found that loss of APOBEC3 causes spontaneous mammary carcinoma and T cell lymphomas in B6 mice. The transcripts of endogenous mouse mammary tumor virus are abundant in the tumor cells prepared from APOBEC3-deficient mice. These results suggest that APOBEC3 contributes to the control of activated endogenous retrovirus.
