A transformant line obtained by transfection of NTH3T3 cells with c-Ha-T24-ras gene was treated with 5mmol/L benzamide,an inhibitor of PARP enzyme for 4 weeks.Some changes in cellular properties of the transformant line were observed.

用 5mmol/L PARP抑制剂苯甲酰胺处理经c-Ha-T24-ras活化癌基因转染得到的转化细胞系，处理4周后发现转化细胞系的某些细胞生物学特性发生了改变，呈现出正常细胞的某些特性。

After treatment of benzamide which is an inhibitor of poly polymerase,β-galactosidase activity assays and PCR analysis were performed to test the deletion of LacZ gene and c-Ha-T24ras gene. The results showed that:(1)LacZ gene was deleted from both A13.4-NIH3T3 cells and B12.7-NIH3T3 cells, but neigher from A13.4-HeLa cells nor B12.7-HeLa cells. So it is possible that there is cell line specificity in gene deletion induced by BA.(2) In A13.4-NIH3T3 cells, LacZ gene and c-Ha-T24ras gene were completely deleted at the same time.(3) The transcription activity of exgenous DNA fragment may have same effect on its sensitivity to the deletion induced by BA.

用聚ADP核糖聚合酶的NAD位点抑制剂苯甲酰胺分别处理四种转化细胞后，检测细胞中整合的外源LacZ基因与c-Ha-T24ras基因的删除情况，结果如下：BA诱导的基因删除可发生于NIH3T3转化细胞系，但不能发生于HeLa转化细胞系；位于同一外源表达载体上的LacZ基因与c-Ha-T24ras基因的删除过程是同步的；外源整合DNA片段的转录强度可能直接影响其被BA诱导删除的敏感性。
