<p>(A) Typical blot, phosphotyrosine screening of mouse aorta tissue homogenates. PE increases tyrosine phosphorylation, and pre-treatment with Src inhibitor PP2 decreases tyrosine phosphorylation. (B) Mean densitometry of phosphotyrosine bands indicated. (C) Phospho-FAK Y925 increases in response to PE in a PP2-inhibitable manner, mean densitometry (n = 9 mice, 3 experiments). (D-E) Phospho-CAS Y165 and phospho-paxillin Y118 increase in response to PE in a FI-14-inhibitable manner, mean densitometry (n = 9 mice, 3 experiments). The brightness of the representative bands in Insets C-E has been uniformly altered for visual display; however, unaltered images were used for densitometry quantitation. *p<0.05, **p<0.01 vs. control, +p<0.05, ++p<0.01, +++p<0.001 vs. PP2+PE or FI-14+PE, unpaired, two-tailed Student’s t-test.</p>
