In schistosomiasis, eggs produced by bisexual infected mature female schistosome worms (FMS) are the main cause of pathological damage to the host and the dissemination of the disease. Single-sex infected female worms (FSS) cannot completely develop to sexual maturity or produce normal eggs. In this study, isobaric tags for relative and absolute quantitation (iTRAQ)-coupled LC-MS/MS was used to explore the proteome of FSS and FMS of Schistosoma japonicum. A total of 1477 differentially expressed proteins (fold change >1.2, P < .05) between FSS and FMS were identified. Bioinformatics analysis indicated that FMS expressed more proteins related to biosynthetic processes, such as eggshell synthesis, ribosomal synthesis, protein folding, cellular detoxification, and metabolic processes such as protein metabolism and glucose metabolism, whereas more proteins related to locomotion and oxidative phosphorylation were expressed in FSS. Our identification and analysis of differentially expressed proteins between FMS and FSS provides new insights to elucidate the molecular biological mechanisms of female worm sexual maturation and reproduction. SIGNIFICANCE: Female Schistosome worms must maintain constant pairing contact with male worms for differentiation of their reproductive organs. Mature female worms can produce infectious eggs, cause serious pathological damage to the host and the dissemination of the disease. Unpaired female worms remain small and sexually immature; they do not spawn normally. In this study, iTRAQ-coupled LC-MS/MS was used to explore the whole proteome of single-sex infected female worms (FSS) and bisexual infected mature female worms (FMS) of Schistosoma japonicum. 1477 differentially expressed proteins (DEPs) between FSS and FMS were identified and analyzed. Further research on DEPs' functions in schistosome sexual maturation and reproductive development might provide theoretical bases to explore female maturation and spawning.

来自单性感染和双性感染的日本血吸虫雌虫基于iTRAQ的蛋白质组谱的比较分析。

在血吸虫病中,由双性恋感染的成熟女性血吸虫蠕虫(FMS)产生的卵是宿主病理损害和疾病传播的主要原因。单性感染的雌性蠕虫(FSS)不能完全发育成性成熟或不能产生正常卵。在这项研究中,用于相对定量和绝对定量(iTRAQ)耦合的LC-MS / MS的等压标记用于研究日本血吸虫的FSS和FMS的蛋白质组。在FSS和FMS之间总共鉴定了1477个差异表达的蛋白质(倍数变化> 1.2,P <.05)。生物信息学分析表明,FMS表达了更多与生物合成过程相关的蛋白质,例如蛋壳合成,核糖体合成,蛋白质折叠,细胞排毒以及新陈代谢过程(例如蛋白质代谢和葡萄糖代谢),而更多的与运动和氧化磷酸化有关的蛋白在FSS中表达。我们对FMS和FSS之间差异表达蛋白质的鉴定和分析为阐明雌性蠕虫有性成熟和生殖的分子生物学机制提供了新的见识。意义:雌性血吸虫蠕虫必须与雄性蠕虫保持恒定的配对接触,以分化其生殖器官。成熟的雌性蠕虫会产生感染性卵,对宿主造成严重的病理损害并传播疾病。未成对的雌性蠕虫仍然很小,并且性未成熟。它们不能正常产卵。在这项研究中,iTRAQ偶联的LC-MS / MS用于研究日本血吸虫的单性感染雌性蠕虫(FSS)和双性感染成熟雌性蠕虫(FMS)的整个蛋白质组。鉴定并分析了FSS和FMS之间的1477个差异表达蛋白(DEP)。进一步研究DEPs在血吸虫性成熟和生殖发育中的功能可能为探索雌性成熟和产卵提供理论基础。
