Task: Answer Verification
Input (English): Question: Do transgenic mice with mammary gland targeted expression of human cortactin develop ( pre-malignant ) breast tumors : studies in MMTV-cortactin and MMTV-cortactin/-cyclin D1 bitransgenic mice?
Answer: From this study, we conclude that development of (pre-malignant) breast tumors in either wild type or MMTV-cyclin D1 mice was not augmented due to mammary gland targeted overexpression of human cortactin.
Output (English): no
