Abstract:
Aim To investigate the effects of sodium phenylbutyrate on cell proliferation,apoptosis and its expression of p21 and survivin genes in human tongue squamous cancer Tca8113 cell line.Methods The cellular proliferation inhibitory ratio was evaluated by MTT assay and the apoptosis and cell cycle of the Tca8113 cell line was detected by FCM.The expression of p21 and survivin genes was analyzed with Western blot and RT-PCR.Results Sodium phenylbutyrate could inhibit the Tca8113 cells proliferation,promote cell apoptosis and arrest the cells at G_1/G_0 phase.The expression of p21 gene in Tca8113 cell line treated by sodium phenylbutyrate was increased,and one of survivin gene was decreased.Conclusions Sodium phenylbutyrate induces up-regulation of p21 gene and down-regulation of survivin gene,which inhibits Tca8113 cell proliferation and induces its apoptosis and arrests the cells at G_1/G_0 phase.And the increase of p21 mRNA expression is negatively correlated with the decrease of survivin mRNA expression(r_s=-0.548,P<0.01),and so is its protein expression(r_s=-0.514,P<0.01).
