Abstract [en]

OBJECTIVE: To study the role of a synthetic insulin-like growth factor-I receptor (IGF-IR) antagonist, picropodophyllin, for mouse preimplantation embryo development in vivo and in vitro. DESIGN: In vitro and in vivo study. SETTING: Hospital-based research unit. ANIMALS: FVB/N mice and mouse embryos. INTERVENTION(S): The effect of picropodophyllin in mouse embryo development in vivo and in vitro, immunohistochemistry, ELISA, polymerase chain reaction. MAIN OUTCOME MEASURE(S): Embryo development, presence of IGF-IR, messenger RNA expression, IGF-I synthesis. RESULT(S): The effect of picropodophyllin on embryo development in vitro and in vivo was not reversible. Mice treated with picropodophyllin 1 to 3 days after mating had a reduced number of blastocysts, 40.5% versus 78.8%, and a higher number of embryos with delayed development, 48.6% versus 11.5%. Insulin-like growth factor-IR protein is present in both phosphorylated and nonphosphorylated form at all stages of embryo development. The relative IGF-IR messenger RNA expression was highest in the oocyte and reduced during development to blastocyst stage. Insulin-like growth factor-I in culture media was reduced after picropodophyllin treatment. CONCLUSION(S): We conclude that IGF-I has an important role in normal mouse embryo development and that its receptor plays an essential role in the embryonic genome activation process.
