| abstractText | Mtv-2 is an endogenous mouse mammary tumor virus (MMTV) that is responsible for the induction of mammary gland tumors in the high mammary gland tumor-incidence strain GR. GR animals inherit four different endogenous MMTVs in addition to Mtv-2: Mtv-3, Mtv-7, Mtv-8 and Mtv-17. In this study we analyzed the involvement of these nonpathogenic endogenous proviruses in the mammary gland tumors caused by Mtv-2. We showed that Mtv-17 is expressed in the mammary gland of GR mice, efficiently packaged into virions, and shed into milk. DNA isolated from both mammary gland tumors and the nonmalignant mammary gland tissues of GR mice contained amplified copies of both newly acquired Mtv-2 and recombinant proviruses with the env gene derived from Mtv-17. A small percentage of these tumors contained predominantly recombinant viruses. These findings suggest a role for Mtv-17 in the mammary gland tumors induced by Mtv-2 in GR mice. |
