Effects of rapamycin on VEGFR-3 expression. A, Western blot analysis of VEGFR-3/Flt-4 expression in LECs and HNSCC cells after rapamycin treatment (100 ng/ml, 72h). B, Expression of pro-lymphangiogenic VEGFR-3 compared to control in the cell lines tested. The intensities of the VEGFR-3 bands were quantified at least in six independent sets of samples and statistical significance was determined using the paired two-tailed t-test.
