已有研究表明,对肿瘤的化疗可导致ATM(ataxia-telangiectasiamutated,ATM)相关的肿瘤细胞多药耐药(multipledrugresistance,MDR)的产生,而炎症因子IL-6水平也与MDR的形成密切相关。但到目前为止,ATM活化在IL-6所引起的MDR形成中的作用仍不明。因此,本实验主要对IL-6在肺癌细胞中引起MDR的通路机制进行研究。 为探究IL-6和ATM在化疗药所致MDR形成中的作用,我们以NCI-H446和A549细胞为小细胞肺癌和非小细胞肺癌模型,首先观察NCI-H446和A549细胞对化疗药顺铂和喜树碱的敏感性,进而采用Westernblot...Documented studies showed that ATM was contributed to the up-regulation of multidrug resistance associated genes. Meanwhile, IL-6 was also reported to play important roles in chemotherapy resistance. But the exact role of ATM in IL-6 induced MDR formation was still unknown. To explore the roles of IL-6 and ATM in chemotherapeutic drugs-induced MDR formation, the IL-6 expression and chemotherapy se...学位:理学硕士院系专业:医学院_微生物学学号:2452010115332
