 AB    In two lines of transgenic rats (pX rats) from WKAH and F344 strains and
       carrying the human T-lymphotropic virus type I pX gene, undifferentiated
       mammary carcinomas developed predominantly in females starting at about
       5 months of age, and there was massive infiltration of granulocytes in
       the tumor tissue. The incidence of the tumor reached about 40% when the
       rats were 12 months old. mRNAs of both pX and host genes Gro and MIP-2,
       which are granulocyte chemoattractants of the interleukin 8 family, were
       highly expressed in the tumor tissue. Since expression and point
       mutation of several oncogenes and the antioncogene were not
       demonstrated, hitherto unidentified novel oncogenic pathways may be
       transactivated by the pX transgene in these pX rats.
