Figure 5: Western-blotting analysis of VEGFR-2 phosphorylation (upper) and FAK phosphorylation (lower). Relative activity was calculated from the amount of phosphorylated protein normalized to that of total protein, which was determined by densito-metric quantification using NIH Image J software (n = 3). NS: no signal. Data are expressed as means ± standard deviation for 3 independent samples. *p < 0.05, **p < 0.01 |
