A-D: Phospho-Akt and phospho-eNOS protein in HUVECs transfected with pre, or anti-miR-21. A: Western analysis (different parts of same blot) and densitometry of p-Akt (serine 473) after transfection with pre-miR-21 for 28 hours; *p=0.03 vs control transfection (n=3); B: Western (different parts of same blot) and densitometry of p-eNOS (serine 1177) after transfection with pre-miR-21 or control pre-miRNA for 48 hours, +/- LY 294002 (10 mM); *p=0.04 (n=6). C: Western analysis (different parts of same blot) and densitometry of p-Akt in cells transfected with anti-miR-21 or control, then subjected to USS (15 dynes/cm2) for 24 hours. D: p-eNOS expression (different parts of same blot) in cells transfected with anti-miR-21 or control, then subjected to USS (15 dynes/cm2) for 24 hours. *p=0.037 (n=3). E: NO production (expressed as ESR arbitrary units) in HUVECs transfected with pre-miR-21 or control, *p=0.007 (n=4).
