摘要: Mouse mammary tumor virus (MMTV) infection causes a high incidence of murine carcinomas by insertion its proviral DNA in the genome epithelial cells. Retroviral can activate flanking proto-oncogenes process called insertional mutagenesis. By sequencing adjacent to MMTV insertions tumors from BALB/c mice infected with C3H-MMTV, we have found common site Fgf10 locus. RT–PCR studies showed that is expressed only those harboring this locus, suggesting proto-oncogene. The oncogenicity was evaluated vivo subcutaneous transplantation retrovirally transduced HC11 cells into mice. Highly vascularized invasive developed indicating act as an oncogene. A survey primary human breast revealed strongly elevated mRNA levels approximately 10% tested, may also be involved subset cancers.
