miR-146a expression in human prostate cancer xenograft mouse models. The miR-146a level was detected using qRT-PCR and described as the fold-change after normalization to U6 RNA in the tumor tissues of different mice groups (n = 6). The tumor tissue from the control mice of the first analysis was used to the calibrator samples. The data are the mean ± SD of one representative experiment. Similar results were obtained in three independent experiments. *P < 0.05, **P < 0.01 compared to the control samples.
