Figure 13From: GDF-15 is abundantly expressed in plexiform lesions in patients with pulmonary arterial hypertension and affects proliferation and apoptosis of pulmonary endothelial cellsAkt phosphorylation by GDF-15 in endothelial cells. GDF-15 induced Akt phosphorylation at Ser437 in human pulmonary microvascular endothelial cells (HPMEC). The cells were stimulated with recombinant GDF-15 protein (50 ng/ml) for 30 to 240 minutes. Akt and Ser437 were determined by immunoblotting. An exemplary blot from n = 3 experiments is presented.Back to article page
