Project description:Sea cucumber, Apostichopus japonicus is a very important species for aquaculture, and its behavior and physiology can respond to the initial change in salinity. It is important to understand the molecular responses of A. japonicus when exposed to ambient changes in salinity In this study, RNA-seq provided a general overview of the gene expression profiles of the intestine of A. japonicus exposed to high salinity (SD40), normal salinity (SD30) and low salinity (SD20) environment.
Project description:The sea cucumber Apostichopus japonicus is a deposit-feeder and vital for marine benthic ecosystems. Hypoxia lasting for several days can lead to massive mortality in A. japonicus. It is important to understand the molecular responses of A. japonicus when exposed to acute changes in DO concentration. In the present study, RNA-seq provided a general overview of the gene expression profiles of the respiratory tree of A. japonicus exposed to dissolved oxygen (DO) of 8 mg/L (DO8), 4 mg/L (DO4) and 2 mg/L (DO2) conditions.
Project description:RNA-seq provided a general overview of the gene expression profiles of the body walls of A. japonicus exposed to strong light (“light”), normal light (“control”) and fully dark (“dark”) environment.
Project description:Sequencing of mononucleosomal DNA during asynchronous mitosis in Schizosaccharomyces pombe, Schizosaccharomyces octosporus, Schizosaccharomyces japonicus and Saccharomyces cerevisiae Samples from mononucleosomal DNA from asynchronous mitosis of four species of budding (Saccharomyces cerevisiae W303-1a) and fission yeasts (S. pombe wild type 972h-, S. octosporus CBS1804, S. japonicus var. japonicus ade12- FY53) were sequenced (Illumina Genome Analyzer IIx and HiSeq 2500) using the single read and paired end protocol.
Project description:Schistosomiasis is a parasitic zoonosis which caused by schistosomes and poses great threat to the health of human and other mammals. Schistosome cercaria must penetrate skin as an initial step to successfully infect the final host. Proteolytic enzymes secreted from the acetabular glands of cercaria contribute significantly to the invasion process. In this study, we designed a new cercaria transformation experiment to get the penetrated cercaria (schistosomula), then a gel-free shotgun proteomic analysis were performed to compare the proteomes of cercaria and schistosomula. 1894 and 1002 proteins were identified respectively, 924 proteins were common in both of two samples, almost take up 92% of the total proteins of schistosomula. The identified proteins were closely associated with nine main biological processes through Gene Ontology (GO) categorical analysis. The identification of the proteins potentially related to skin penetration offer a global overview of changes during cercaria skin invasion, providing clues into how they involve in the penetration process. Various proteases and peptidases were detected, and were differentially existed before and after cercaria transformation, suggesting proteases-specific roles and complexity mechanism during invasion.
