Abstract 【目的】为探讨DNA多聚酶β在神经细胞损伤中的作用与机制，构建其重组腺病毒载体，并在PC12细胞中表达。【方法】RT-PCR获取大鼠DNA多聚酶β(POLβ)的编码序列，TA克隆测序，酶切POLβ基因并连入穿梭质粒pAdTrack-CMV，电转至含腺病毒pAdeasy骨架质粒的大肠杆菌BJ5183。重组腺病毒质粒(pAd-polβ)和Lipofectamine2000转染293细胞，用重组腺病毒感染PC12细胞。【结果】10个TA克隆中有3个克隆的序列与GENE BANK中大鼠POLβ cDNA序列完全一致，同源重组检测时30个克隆中有8个含目标条带。DNA序列正确的POLβ重组腺病毒质粒转染293细胞后，感染Ad-polβ的293及PC12细胞荧光显微镜下可见绿色荧光，重组腺病毒Ad-polβPCR鉴定含目标条带，Ad-polβ感染PC12细胞Western Blot检测到POLβ蛋白表达。【结论】成功构建了大鼠DNA多聚酶β的腺病毒重组体并在PC12细胞中表达
