  1. 01LabIn vitro (cells)Mechanism

    In cultured fetal sheep cardiomyocytes, IGF-1R activation with LONG R3 IGF-1 resulted in ERK signaling.

    Summary
    IGF-1R and IGF-2R activation each resulted in ERK signaling, but IGF-2R activation alone induced CaMKII signaling, resulting in hypertrophy of cardiomyocytes in the late gestation sheep fetus.
    2 context sentences
    Summary · context
    Cultured cardiomyocytes were treated with either LONG R(3)IGF-1, an IGF-1R agonist
    Summary · context
    Fetal sheep hearts (125 ± 0.4 days gestation) were dissected, and the cardiomyocytes isolated from the left and right ventricles for culturing.
  2. 02LabIn vitro (cells)Mechanism

    In cultured fetal sheep cardiomyocytes, IGF-1R activation with LONG R3 IGF-1 did not induce CaMKII signaling, which IGF-2R activation alone induced.
