(1) Connective Tissue Growth Factor (CCN2) protects against oxidative stress and cell death by activating the cytoprotective signaling pathway PI3-kinase/Akt/GSK-3β in adult cardiomyocytes and endothelial cells. Cardioprotective genes are upregulated in cardiomyocytes stimulated with CCN2. This cardioprotection is attenuated when a PI3-kinase inhibitor or Akt-inhibitor is present.
(2) Mice with overexpression of CCN2 in the heart showed attenuated hypertrophy compared to wild type mice when subjected to angiotensin II-infusion. Pro-hypertrophic NFAT-activity was reduced when CCN2 was present in neonatal cardiomyocytes exposed to mechanical stretch, indicating that CCN2 protects against hypertrophy through modulation of NFAT-activity.
