Figure 1. Let-7a expression in prostate cancer tissues and cells measured by real-time RT-PCR.

Figure 1

Real-time RT-PCR show that the relative expression of let-7a in twenty-six prostate cancer samples, and in prostate cancer cell lines LNCap, PC3, DU-145 is higher than that in their adjacent non-cancerous specimens and the normal prostate epithelial cell PrEC. Data are shown as percent of mean signals in tissues and cells from three independent measurements. RNU6B was measured in parallel and used to normalize the expression level of let-7a in each experiment. Values represent means and error bars represent the SEM. (* p<0.01, ** p<0.01; Mann-Whitney-U test).
