Abstract:
Objective To investigate the biological effects of As 2O 3 and its mechanism on human oral squamous carcinoma cell line in vitro . Methods The effects of As 2O 3 on Tca8113 cell line were investigated in vitro with morphological method, MTT, clone forming, DNA ladder, TUNEL assay and flow cytometry(FCM). Results As 2O 3 had marked suppressive effect on the growth of Tca8113 cell line. The growth suppression rate of the Tca8113 cells was 76.3% shown by MTT. DNA ladder, TUNEL and FCM showed As 2O 3 could induce the apoptosis of Tca8113 which might be related to cell cycle arrest shown by FCM. Conclusion As 2O 3 can inhibit the growth and induce the apoptosis of oral squamous carcinoma cell in vitro .
