Modulation of Pak1 activity in androgen-responsive and androgen-insensitive prostate cancer cells inhibits directional migration of prostate cancer cells.
a–c, human androgen-responsive LNCaP and androgen-insensitive PC3 and LNCaP C4-2 cells were either overexpressed with CA-Pak1 or DN-Pak1 (in the case of PC3 and LNCaP), or made stable cell lines expressing ShPak1 (in the case of LNCaP C4-2) and then subjected to a migration assay on fibronectin in the presence of 50 μm EGF. The data are presented as mean ± S.D. n = 3 of quadruplicate experiments. *, p < 0.001; #, p < 0.05; Δ, p < 0.01; versus control experiments within the same group.
