摘要: 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。伴随这一现象,检测到细胞中整合的外源T24-ras基因发生了丢失。
Abstract: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.Concomitant with these changes was the deletion of the exogenous c-Ha-T24-ras which had been integrated into genomic DNA of recipient cells.
