Project description:Transcriptional profiling using two subsequent developmental stages of Schistosoma mansoni (Egg vs. Miracidium; Cercaria vs. 7-days-old Schistosomulum; 7-days-old Schistosomulum vs. Adult worms Two conditions experiment; Developmental Stage 1 vs. Developmental Stage 2
Project description:In the complex lifecycle of schistosomes, four developmental stages are closely associated with their definitive hosts: cercaria (infective stage), schistosomula and adult worm (parasitic stages), egg (pathogenic- and pathophoresis-stage). We have examined the gene expression profiles of Schistosoma japonicum in the four developmental stages. Genes with different expression patterns were identified and the information obtained will help indentify new anti-schistosomal intervention targets in the future.
Project description:Analysis of differentially expressed gene of different parasite stage helps to determine which genes are likely to be the key players in transition through a developmental stage, thus help to further understand schistosome biology and host-parasite relationship, facilitate the discovery of novel gene products than could represent targets for the development of new drugs and vaccines to control schitosomiasis.Samples were analyzed at cercariae, egg and adult worm stage. Keywords = Schistosoma japonicum Keywords = different development stage Keywords = differentially expressed gene Keywords: time-course

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).
