ABSTRACT
【Objective】 To explore the therapeutic mechanismof arsenic trioxide(AS2O3),the active component of arsenolitumininhibitingtumor.【Methods】Humanlung adenocarcinoma cells(LAC) at logarithmic growth phase were culturedin vitro for 24 hours,and then were cocultured with arsenic trioxide(AS2O3) in the dosages of 0.75,1.0,1.5 and 2.0 mg/Lrespectively.Meanwhile,model control group was set up.The morphological features of LAC in different groups were observed under reverse microscope,growth-inhibitory rate of LAC was examined by methylthiazolyltetrazolium(MTT) assay,andthe expression of p53 gene was detected by enzyme-linked immunosorbent assay(ELISA) method.【Results】AS2O3in different dosages obviously inhibited the proliferation of LACin a time-effect manner,and markedly increased the expression of p53 gene(P
