Summary of Vpr-induced tumor regression of WT and DOX-resistant neuroblastoma in C57-SCID mice.

<p><b>Note:</b> Tumor sizes were measured at 39 days post-intratumoral injection (Week 0). Levels of statistical significance of the t-test results between the Adv control and the testing groups (Ad-Vpr or Ad-F34IVpr): *, p<0.05; **, p<0.001; Weighted average sums of the t-tests <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0011466#pone.0011466-Tan1" target="_blank">[31]</a> for both wild type and Dox-R mice showed statistic differences at the level of p<0.05.
