【摘要】目的：探讨AICARFT、mTOR在人肺腺癌亲本株A549及培美曲塞诱导人肺腺癌耐药株A549／PEM中表达变化及意义。方法流式细胞术检测A549及A549／PEM细胞周期分布， RT－PCR、Western blot分别检测AICARFT、mTOR在A549及A549／PEM的mRNA及蛋白表达变化。结果流式细胞术检测细胞周期提示处于S期的A549／PEM较A549明显增多，分别为（36．61±1．36）％和（27．16±1．08）％（ P＝0．001）；RT－PCR检测mRNA示A549／PEM的AICARFT及mTOR基因表达与A549相比均表达上调（P＜0．05）；Western blot检测蛋白示A549／PEM的AICARFT及mTOR蛋白表达与A549相比均表达上调（P＜0．05）。结论人肺腺癌培美曲塞获得性耐药细胞株出现细胞周期重分布，培美曲塞获得性耐药可能与AICARFT、mTOR表达上调相关。%Objective To investigate the expression of AICARFT and mTOR in lung adenocarcinoma cell line A549 and pemetrexed resistant human lung adenocarcinoma cell line A549/PEM.Methods The distri-bution of cell cycle was evaluated by flow cytometry assay.The expression of AICARFT and mTOR in A549 and A549/PEM were detected by RT-PCR and Western blot.Results Flow cytometry analysis showed that S phase in A549/PEM was higher than
that in A549((36.61 ±1.36)%vs(27.16 ±1.08)%(P=0.001)).mRNA over expression of AICARFT and mTOR in A549/PEM were detected by RT-PCR(P<0.05).Protein over expres-sion of AICARFT and mTOR in A549/PEM were detected by Western blot.(P<0.05).Conclusion High level of AICARFT and mTOR may be connected with pemetrexed acquired drug resistance in lung adenocarcinoma.The cycle of pemetrexed resistant human lung adenocarcinoma cancer cell line A549/PEM is redistributed. 【总页数】5页(337-341)
