摘要: 目的 比较氯氰菊酯选育后抗性淡色库蚊与敏感淡色库蚊蛋白差异表达情况,揭示淡色库蚊抗氯氰菊酯杀虫剂的机制。方法 利用同位素相对和绝对定量(iTRAQ)技术,结合液相色谱/串联质谱(LC?MS/MS)分析技术,对氯氰菊酯敏感与抗性淡色库蚊进行蛋白组定量分析。结果 共鉴定出164种蛋白在氯氰菊酯抗性选育前后差异表达,其中上调蛋白54种、下调蛋白110种,大量细胞骨架结构与组成相关的表皮蛋白、幼虫表皮蛋白、蛹表皮蛋白及表皮结构成分蛋白在淡色库蚊氯氰菊酯抗性选育前后差异表达。通过平行反应监测验证了能量产生与转换、翻译、核糖体结构与生物发生、脂质转运与代谢、翻译后修饰、蛋白质周转、分子伴侣、细胞骨架、细胞内运输等13种类型的蛋白在淡色库蚊氯氰菊酯选育后差异表达,可作为潜在抗性发生标记物。结论 氯氰菊酯抗性淡色库蚊中同时存在表皮抗性及代谢抗性等多种杀虫剂抗性机制,与抗氯氰菊酯杀虫剂相关的表皮基因及细胞色素P450蛋白酶可能在淡色库蚊氯氰菊酯抗性中发挥了重要作用。

Abstract: Objective To compare the differentially expressed proteins between cypermethrin?resistant and ?sensitive Culex pipiens pallens, so as to unravel the mechanism underlying the resistance to cypermethrin in Cx. p. pallens. Methods A quantitative proteomic analysis was performed among cypermethrin?sensitive and ?resistant isolates of Cx. p. pallens using isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with liquid chromatography with tandem mass spectrometry (LC?MS/MS). Results A total of 164 differentially expressed proteins were identified between cypermethrin?sensitive and ?resistant isolates of Cx. p. pallens, including 54 up?regulated proteins and 110 down?regulated proteins. A large number of cuticular proteins, larval cuticular proteins, pupal cuticular proteins and cuticular structural constituent proteins, which are associated with cytoskeletal structure and components, were differentially expressed between cypermethrin?sensitive and ?resistant isolates of Cx. p. pallens. Thirteen proteins, which were involved in energy production and conversion, translation, ribosomal structure and biogenesis, lipid transport and metabolism, post?translational modification, protein turnover, chaperones, cytoskeleton and intracellular transportation, were validated to be differentially expressed between cypermethrin?sensitive and ?resistant isolates of Cx. p. pallens, which may serve as potential markers of cypermethrin resistance. Conclusion Multiple insecticide resistance mechanisms contribute to the resistance to cypermethrin in Cx. p. pallens, including cuticular resistance and metabolic resistance, and the cuticular protein genes and cytochrome P450 enzymes may play an important role in the resistance of Cx. p. pallens to cypermethrin.
