Abstract:
Objective To construct PES1 shRNA stable expression cell lines in tongue squamous cell carcinoma ( TSCC) cells and to study the effect of knockdown of PES 1 on the growth of TSCC cells .Methods Recombinant lentivirus carrying PES1 shRNA was packaged and obtained in 293T cells.TSCC cells (Tca8113, SCC6 and SCC15) were infected with the lentivirus and selected for stable cells .PES1 expression was identified by Western blot .The effect of inhibition of PES1 on the growth and cell cycle of TSCC cells was detected by growth curve and flow cytometry .Results TSCC cells stably expressing PES1 shRNA were constructed.Knockdown of PES1 inhibited cell proliferation and induced cell cycle ar-rest at G0/G1 phase.Knockdown of PES1 inhibited expression of cyclin D1 in TSCC cells.Conclusion Inhibition of PES1 results in reduced cell proliferation , cell cycle arrest at G 0/G1 phase and reduction of cyclin D 1 expression in TSCC cells . PES1 may be a target for TSCC gene therapy .
