Effect of c-Jun siRNA on angiogenesis <i>in vitro</i> stimulated by over-expression of HPV-16 E6 or E7 in A549 cells.

<p>HPV-16 E6- (A) or E7- (B) transfected A549 cells were co-transfected with c-Jun siRNA (Si-1 or Si-2). Left: The tube formation was observed under a phase-contrast microscope (20×). Right: The total tube length in three random view-fields per well was by Scion image software measured and average value was calculated. All data are expressed as mean ± SD of three independent experiments. **<i>P</i><0.01.
