ABSTRACT

Objective To study the inhibitory effect of triethyltin chloride(TETC) on proliferation of rat C6 glioma cells in vitro and its mechanism and provide basis for research on TETC in treatment for glioma.Methods MTT assay was performed to determine the inhibitory rate of 0.5,1.0 and 2.0 ?mol?L-1 TETC on rat C6 glioma cells for 24 and 48 h.The changes of nucleus of C6 glioam cells treated with 0.5,1.0 and 2.0 ?mol?L-1 TETC for 48 h were observed by fluorescent microscope.Flow cytometry was used to assess the effects of 0.5,1.0 and 2.0 ?mol?L-1 TETC on cell cycle and apoptosis in rat C6 glioma cells for 48 h.Results 0.5,1.0 and 2.0 ?mol?L-1 TETC inhibited the proliferation of C6 glioma cells in vitro,and the inhibitory rates were 7.92%,9.51%,19.03% and 15.62%,36.16%,41.92% in 24 h TETC treated group and 48 h TETC treated group,respectively.The inhibitory rate of TETC on C6 glioma cells determined by MTT assay increased in a dose-dependent and time-dependent manner,and there were significant differences of the inhibitory rates at 48 h between control and various doses groups as well as between various doses groups(P
