【摘要】 由传染性脾肾坏死病毒(ISKNV)感染导致的病毒病给我国鳜鱼养殖带来严重危害。为从全局角度探究ISKNV与宿主细胞的相互作用,本研究采用iTRAQ技术分析了ISKNV感染鳜鱼脑细胞(CPB)后24h和72h蛋白组,共获得6363个唯一肽段,其中2731个蛋白与已知蛋白同源。差异蛋白分析表明:24h感染组相对对照组共有232个差异蛋白,其中141个蛋白上调,91个蛋白下调;72h感染组相对对照组共有199个差异蛋白,其中111个蛋白上调,88个蛋白下调。蛋白功能富集分析显示差异蛋白与生物调节、单有机体过程、代谢过程、细胞转化、催化活性、绑定分子功能、大分子配合物、细胞和细胞器有关。通过免疫印迹验证了G6PDH、β-tubulin和RPL11的蛋白在不同组之间的差异与i TRAQ结果一致,表明i TRAQ得到的差异蛋白组结果可靠。本研究为进一步研究ISKNV感染致病机制和寻找潜在的药物靶标奠定基础。更多还原

【Abstract】 Infectious spleen and kidney necrosis virus(ISKNV), the causative agent of Mandarin fish(Siniperca chuatsi) infectious spleen and kidney necrosis,has drastic effects on Mandarin fish fisheries in our country. Aiming to detectthe interactions between ISKNV andhost from a whole perspective, i TRAQ technique was used for analyzing the proteomic of Mandarin fish brain cell(CPBs) at 24 h and 72 h after ISKNVinfection. A total of 6363 unique peptides corresponding to2731 proteins were identified, and there respectivelywere 232 which including 141 up-regulated proteins and 91 down-regulated proteinsand 199 which including 111 up-regulated proteins and 88down-regulated proteins altered proteins at 24 h and 72 h comparing with mock-infected cells.Gene ontology analysis demonstrated that a number of proteins were related to biological regulation,single-organism process, metabolic process, cellular process, catalytic activity, binding,macromolecular complex, celland organelle. Moreover,the western blot analysis demonstrated the changes ofsome proteins level between different groups including G6PDH、β-tubulin and RPL11,which corresponded to the resultsof i TRAQ and verified the reliability of the proteomics data.更多还原
