长、凋亡与细胞周期状况。结果：MTT 实验显示siRNA转染组的抑制率明显高于阴性对照组和空白对照组(P<0.05)，阴性对照组
与空白对照组的对比无明显差异(P>0.05)。流式细胞术实验表明siRNA 转染组的细胞凋亡率明显高于阴性对照组和空白对照组
(P<0.05)，阴性对照组与空白对照组的对比无明显差异(P>0.05)。流式细胞术实验表明siRNA转染组的G0/G1 期细胞数目较阴性
对照组和空白对照组增多明显(P<0.05)，同时siRNA转染组的S、G2/M 期细胞数目较阴性对照组和空白对照组明显减少(P<0.

| Objective:To investigate the effects of RNA interference CMTM7 on apoptosis of lung adenocarcinoma A549 cell by
the.Methods:Selected lung adenocarcinoma A549 cell were divided into siRNA group, negative control group and blank control group,
and the RNA interference CMTM7 vectors were transfected into the logarithmic growth of A549 cells, observed A549 cell growth, and
the apoptosis and cell cycle status was detected.Results:MTT experiment showed that the inhibition rate in siRNA transfection group
was significantly higher than that of the negative control group and blank control group (P <0.05), while the difference between the
negative control group and the control group were not significant (P> 0.05). Flow cytometry showed the apoptosis rate in the siRNA
transfection group was significantly higher than that of the negative control group and blank control group (P <0.05), while the difference
between the negative control group and the control group were not significant (P> 0.05). Flow cytometry experiments showed that the
number of G0 / G1 phase cell in the siRNA transfection group was increased with significantly difference compared with blank control
group and negative control group (P <0.05), while the number of G2 /Mphase cell in the siRNA transfection group was less than that of
the control group and negative control group (P <0.05), but it had no significant difference between the blank control group and negative
control group (P> 0.05).Conclusion:RNA interference CMTM7 can promote lung adenocarcinoma A549 cell apoptosis, inhibit the
growth of tumor cells, and its mechanismmay be achieved by interfering with the cell cycle. |
