Analysis of microRNA data for normal and prostate cancer sera.

<p>After data set normalization, the natural log of the ratio of the signal for a specific probe over the same probe from the normal serum sample was taken. 15 miRNAs showed up-regulation in all stage 3 and 4 prostate cancer samples when compared to sera from normal male donors. These miRNAs are listed below each data set. Five stage 3 and 4 prostate cancer sera (Yellow), and 8 normal male donor sera (red) were analyzed. Vertical lines indicate plus or minus one standard deviation of the mean.
