Figure Lengend Snippet: ( A ) Representative immunoblots and the effect of VEGFA (50 ng/mL; 1, 5, 10, 30 min) on eNOS, eNOS pS1177, AKT, AKT pS473, VE-cadherin, VE-cadherin pY685, c-Src, SFK pY418, and tubulin in cultured Human Retinal Microvascular Endothelial Cells (HRMEC) treated with a PBS vehicle or 1 mM L-NMMA for 1 hr. ( B ) Quantification of eNOS pS1177/total eNOS (normalized to tubulin). ( C ) Quantification of AKT pS473/total AKT (normalized to tubulin). ( D ) Quantification of VE-cadherin pY685/total VE-cadherin (normalized to tubulin). ( E ) Quantification of SFK pY418/total c-Src (normalized to tubulin) Mean ± S.E.M. n = 3 independent experiments. *, ***p<0.05, 0.001 (indicates significance between vehicle and L-NMMA-treated samples, stimulated with VEGFA as indicated). Two-way ANOVA, Sidak’s multiple comparison test.
Article Snippet: For immunoblotting, the following antibodies were used as primaries: mouse-anti-α−tubulin (1:1000, Sigma, T9026), mouse anti-eNOS (1:1000, Abcam, ab76198), mouse anti-eNOS pS1177 (1:1000, BD, 612392), rabbit anti-Akt (1:1000, Cell Signaling, 9272S), rabbit anti-Akt pS473 (1:1000, Cell Signaling, 4058S), rabbit anti-Src (GD11 clone) antibody (1:1000, Merck Millipore, Mouse, 05–184), rabbit anti-Src pY418 antibody (1:1000, Invitrogen, 44–660G), goat anti-VE-cadherin (1:1000, R and D, AF1002), and rabbit anti-VE-cadherin pY685 (1:1000, DOI:10.1038/ncomms2199).
