Abstract
Activation of the c-Src tyrosine kinase has been implicated as an important step in the induction of mammary tumors in both mice and humans. To directly assess the effect of mammary gland-specific expression of activated c-Src, we established transgenic mice that carry a constitutively activated form of c-src under transcriptional control of the murine mammary tumor virus long terminal repeat. Female mice derived from several independent transgenic lines lactate poorly as a consequence of an impairment in normal mammary epithelial development. In addition to this lactation defect, female mice frequently develop mammary epithelial hyperplasias, which occasionally progress to frank neoplasias. Taken together, these observations suggest that expression of activated c-Src in the mammary epithelium of transgenic mice is not sufficient for induction of mammary tumors.
