Project description:In this study, we isolated and identified the small RNAs associated with the S. japonicum Argonaute protein, SjAgo1, by HITS-CLIP combined with bioinformatic analysis. These data reveal a genome-wide miRNA-mRNA interaction map in S. japonicum in vivo, which will help us understand the complex gene regulation network in this pathogen and thereby facilitate to develop novel approaches against Schistosomiasis.
Project description:The gogal of this study is to use RNA-Seq to systematically investigate the dynamics of the liver transcriptome over Schistosoma japonicum infection.

Project description:To investigate microRNAs (miRNAs) involving in the regulation of the schistosome development and survival, we compared miRNA expression profiles of adult Schistosoma japonicum derived from yellow cattle and water buffalo using high-throughput sequencing with Illumina Hiseq Xten.
Project description:Chinese and Philippine strains of the blood fluke Schistosoma japonicum present clear and distinctive phenotypes in areas of fecundity, pathology, drug sensitivity and immunology. Despite these differences large scale sequencing efforts have focused solely on Chinese mainland strain of the parasite. We have undertaken a comparative genomic hybridisation (CGH) approach to highlight some of the structural differences in the genome of two of the major geographical isolates of S. japonicum. We identified seven distinct regions of the S. japonicum genome that present differential CGH between Chinese and Philippine strains of the blood fluke Schistosoma japonicum, representing either deletion or duplication regions in the Philippine strain. Within these regions, genes that may be related to phenotypical differences are identified and discussed.
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.

Genomic DNA was isolated from adult (7 week post cercarial challenge) Schistosoma japonicum Chinese and Philippine isolates and separate maleand femalesamples comparatively hybridised on an Agilent customn designed oligo microarray.
