Abstract:
:To determine whether murine mammary growth is modulated by local insulin-like growth factor-1 (IGF-1) production, expression of recombinant IGF-1 was directed to the mammary glands of transgenic mice using an ovine prepro IGF-1 cDNA under control of the mouse mammary tumor virus-long terminal repeat (MMTV-LTR) promoter. Bioactivity of recombinant IGF-1 in transgenic mouse milk extracts was demonstrated by a concentration-dependent increase in [3H]thymidine incorporation in clonal bovine mammary epithelial cells (MAC-T) compared with control mouse milk extracts; moreover, addition of excess recombinant human insulin-like growth factor binding protein-3 (rhlGFBP-3) abolished the increase in [3H]thymidine incorporation attributed to recombinant IGF-1 in transgenic mouse milk. Recombinant IGF-1 was produced in mammary tissue of virgin and pregnant transgenic mice, and secreted into milk of lactating mice. However, recombinant IGF-1 was not detected in serum from transgenic mice; and ligand blot analysis of serum insulin-like growth factor binding proteins (IGFBPs) indicated no differences owing to transgene presence. In peripubertal virgin mice at 49 d of age, the frequency of appearance of mammary alveolar buds was significantly higher in MMTV-IGF-1 than in CD-1 mice, and was unaffected by ovariectomy or estradiol treatment. In conclusion, mammary synthesis of recombinant IGF-1 enhances the rate of development of alveolar buds in mammary glands of virgin transgenic mice.
