Project description:Rats and mice were infected with Schistosoma japonicum, and the worms were collected from infected rats and mice. Worms in rats were exposed to high level of NO, while the worms in mice were not. Then a S-nitrosocysteine proteomics of Schistosoma japonicum collected from infected rats and mice was performed and the data were collected.

Project description:It is well recognized that parasitic helminth infections, which afflict more than one billion people globally, correlate with a decreased prevalence of metabolic diseases, including obesity and type 2 diabetes, but the molecular mechanisms involved remain to be determined. Using microarrays, we quantified the temporal gene expression profiles in the liver of Schistosoma japonicum-infected C57BL/6 mice at 9 weeks post infection with that from uninfected mice as controls. More than 150 miRNAs were differentially expressed in the liver during S. japonicum infection, and miRNA-mRNA network would provide new evidence for the negtive correlation between S. japonicum infection and metabolism.

Project description:To date, 115 miRNAs genes (precursors) have been registered in miRBase for Schistosoma mansoni, and 56 for Schistosoma japonicum (225 and 79 mature miRNA, respectively). miRNAs have not been systematically described in Schistosoma haematobium. Our aim in this study was to systematically characterize and quantify miRNA in Schistosoma by species, developmental stage and sex and to test the usefulness of this characterization in biomarker discovery for infection. We found read evidence for the expression of 65/225 (36 precursors) known S. mansoni miRNA and 76/79 (55 precursors) of the known S. japonicum miRNA. We report a handful of novel miRNA in each of these species and provide a curated list of S. haematobium miRNA. We report differences of miRNA expression by species, sex and developmental stages. Lastly, we present preliminary results of miRNA deep sequencing from infected specimens (mouse and human).

Project description:We have used a Schistosoma japonicum infected murine model with in vivo sub-lethal dosages of praziquantel against adult parasites. Differential gene expression of parasites was followed between 30 minutes and 24 hours post- drug administration, using a whole transcriptome microarray platform. Differential gene expression was considered separately between parasite gender. Total RNA was isolated from adult (7 week post cercarial challenge) Schistosoma japonicum male and females. Gene expression was determined through hybridisation on an Agilent custom designed oligo microarray.

Project description:More than 40 species of mammal have been reported to be infected naturally with Schistosoma japonicum (Chinese mainland strain) in China. The reed vole, Microtus fortis, is the only known mammalian host in which the schistosomes are unable to mature and cause significant pathogenic changes. Gene expression profiling of the 10 day old schistosomula was performed. Microarray analysis was also used to identify differences in gene expression between Schistosoma japonicum schistosomula from BALB/c mice and from Microtus fortis. 10 day old schistosomula were isolated, total RNA obtained and Agilent one colour labeling used. A custom designed Agilent microarray was used to determine what differential gene expression occurs between parasites maintained in either a permissive (mouse) or non-permissive (vole) hosts.

Project description:Macrophages initiate, modulate, and also serve as final effector cells in immune responses during course of schistosomal infections. Presently, we discussed the roles of the gene expression profile and functional changes of macrophages in immune responses against the Schistosoma japonicum by microarray experiments. Hierarchical clustering analysis demonstrated that a significant switch in gene transformation associated with a type-1 response and linked with a type-2 cytokine phenotype occurs between 4.5 and 8 weeks post-infection. Moreover, the gene profiles at 3 later time-points following egg challenge were similar in complexity and magnitude. These data also showed that there are mostly inhibition in gene expression related TLR, IFN, MHC and TNFrsf at the switch between 4.5 and 8 weeks post-infection, It is suggested that these immunomodulatory genes may be down-regulated in resistance against S. japonicum eggs and granuloma pathology. The induction of alternatively activated macrophage was important for dampening the inflammation in hepatic granulomas and contributing to a decrease in cytotoxicity. The genes expressions involved in repair/remodeling during liver fibrosis were also observed after eggs production. Understanding these immune mechanisms related to parasite resistance, pathology, and growth with regard to the disease will be helpful in further studies on S. japonicum.

Project description:miRNA profiling of S. japonicum infected mouse plasma comparing control untreated mouse plasma. Schistosomiasis, caused by dioecious flatworms in the genus Schistosoma, is torturing people predominantly in the developing countries. Knowledge on schistosome-host interaction and its parasitism may result in the development of novel strategies for schistosomiasis control. MicroRNAs (miRNAs) are involved in a wide range of biological processes including development, cell proliferation, metabolism ,signal transduction, et al. Circulating miRNAs are not only important biomarker associated the process of pathogenesis in many diseases and also are able to regulate target gene expression in recipient cells, just like hormones. In the present study, we investigated circulating miRNA profile associated with S. japonicum infection in mice using miRNA microarray.
