Notch signaling regulates platelet-derived growth factor receptor-beta expression in vascular smooth muscle cells.

abstract：RATIONALE:Growth differentiation factor 11 (GDF11) is a member of the transforming growth factor-β super family of secreted factors. A recent study showed that reduced GDF11 blood levels with aging was associated with pathological cardiac hypertrophy (PCH) and restoring GDF11 to normal levels in old mice rescued PCH. ...
