ABSTRACT
<p><b>UNLABELLED</b>Objetive To investigate the effects of PKF118-310 on cell cycle and proliferation of K562 cell lines and its mechanism.</p><p><b>METHODS</b>After treatment of PKF118-310 with different concentration, the proliferation inhibition on K562 cell lines was detected by MTT, the existance of β-catenin and TCF-4 in the cells was observed by immunohistochemistry. The change of the cell cycle was detected by flow cytometry. The expressions of caspase-3, β-catenin, TCF and BCL-9 were detected by Western blot.</p><p><b>RESULTS</b>PKF118-310 can inhibit the proliferation of K562 cell line by S phase blocking. The β-catenin and TCF in the cells were observed by immunohistochemistry. After treating this cell line with PKF118-310 of different concentrations for 72 h, the expression level of caspase-3 increased, the expression levels of β-catenin, TCF and BCL-9 significantly decreased.</p><p><b>CONCLUSION</b>PKF118-310 induces cycle arest of K562 cells at the S phase and inhibits the proliferation of these cells through decreasing β-catenin/TCF/BCL-9 thrascriptional activity.</p>
