Cell growth inhibition in three prostate cancer cell lines on the sixth day after transfection.

The data are presented as the means ± SD (n = 10). An asterisk (*) indicates that the growth inhibition of C4-2 and LNCAP cells in Group 6 was significantly different from that in Groups 1, 2, and 4 (P<0.05). A triangle (Δ) indicates that the growth inhibition of C4-2 and LNCaP cells in Group 6 was significantly different from that of the PC-3 cells in the same group (P<0.05).
