摘要卵巢癌是目前死亡率最高的妇科疾病，70%的患者因在晚期确诊而难以得到有效的治疗。现在需要从天然或者合成的化合物中筛选一种强有力的、具有选择性的、安全的口服抗PDI因子，回复肿瘤细胞的药敏性，用于卵巢癌的伴侣治疗。本研究根据文献me-too合成一种抗PDI因子，用于本课题构建的抗PDI因子检测系统的验证。针对抗PDI因子细菌检测体系，本研究采用基因敲除、基因置换等技术构建大肠杆菌dsbA突变体，然后需要采用构建报告基因等手段来构建，最终通过细菌报告基因表达来指示待测物质的抗PDI活性。抗PDI因子的me-too合成和大肠杆菌dsbA突变体的成功构建为最终抗PDI因子检测系统的构建打下了坚实的基础。63953

Title  ：The Construction of an anti-PDI factor testing system in Escherichia coli dsbA mutant 

Abstract Ovarian cancer is one of the leading causes of death in women with gynecological cancers in the world. About 70% of ovarian cancer cases are diagnose data late stage and therefore, poorly treatable. With the resistant tumoral cells being appeared, it is necessary to R&D one potent, target, and safe small-molecule inhibitors of PDI from natural or synthetic compounds to recover the sensitivity of these anti-tumor drugs. In the present study, an anti-PDI factor is chemically synthesized me-too to verify the availability of anti-PDI screening system. As for the construction of anti-PDI screening system, some interdisciplinary methods were used here, such as gene deletion, gene substitution and finally construct target report gene in Escherichia coli dsbA mutant. The synthesis of anti-PDI factor and the construction of E.coli dsbA mutant are basic to test anti-PDI factor detection system next.
