Insulin-like growth factor-II induces hypertrophy of adult cardiomyocytes via two alternative pathways.

Abstract

Insulin-like growth factor (IGF)-II is known to induce hypertrophy of isolated adult rat ventricular cardiomyocytes cultured in the absence of serum. However, it is not known how the growth factor exerts this hypertrophic effect. We show here that IGF-II induces hypertrophy of the cultured cardiomyocytes via two alternative pathways: (1) an IGF-I receptor… (More)
