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.
