ABSTRACT
<p><b>OBJECTIVE</b>To investigate the phosphorylation intensity of MAPK pathway molecular Erk1/2 and the proliferation of prostate cancer cell line PC-3M.</p><p><b>METHODS</b>Flow cytometry and RT-PCR were employed to study the ratio of different cell cycles and phases, respectively, before and after GM-CSF stimulation. Erk1/2 phosphorylation intensity was examined by Western blot simultaneously.</p><p><b>RESULTS</b>The rate of PC-3M cells at S and G2/M stages and the expression intensity of Ki-67 increased after GM-CSF incubation in a dose-dependent manner. The phosphorylation intensity of Erk1/2 increased remarkably after stimulation with GM-CSF.</p><p><b>CONCLUSION</b>The intensification of Erk1/2 phosphorylation is one important molecular mechanism of the proliferation of hormone-independent prostate cancer.</p>
