Project description:MicroRNAs (miRNAs) are involved in nearly every biological process examined to date. Mounting evidence show that some spermatozoa specific miRNAs play important roles in the regulation of spermatogenesis and germ cells development, but little is known of the exact identity and function of miRNA in sperm cells or their potential involvement in spermatogenesis and germ cells development. Here, we investigated the spermatozoa miRNA profiles using illumina deep sequencing combined with bioinformatic analysis using zebrafish as a model system. Deep sequencing of small RNAs yielded 12 million raw reads from zebrafish spermatozoa. Analysis showed that the noncoding RNA of the spermatozoa included tRNA, rRNA, snRNA, snoRNA and miRNA. By mapping to the zebrafish genome, we identified 400 novel and 204 conserved miRNAs which could be grouped into 104 families, including zebrafish specific families, such as mir-731, mir-724, mir-725, mir-729 and mir-2185. We report the first characterization of the miRNAs profiling in zebrafish spermatozoa. The obtained spermatozoa miRNAs profiling will serve as valuable resources to systematically study spermatogenesis in fish and vertebrate.

Project description:Zebrafish (Danio rerio) model system have used widespread vertebrate investigations for genetic and cell biological analyses, and is suitable for small molecular screens such as chemical, toxicity and drug in order to use for human diseases and drug discovery . Recently, These powerful zebrafish model increasingly apply to human metabolic disease such as obesity and diabetes and toxicology. Despite a lot of advantages, proteomics research at zebrafish has received little interest in comparison with genetic and biological research using histology and in situ hybridization. Protein lysine acetylation is one of the most known post-translational modifications with dynamic and reversibly controlled by lysine acetyltransferase such as histone acetyltransferases and lysine deacetylase such as histone deacetylases and sirtuins family.Also, during the past year, global lysine acetylome studies using MS-based proteomics approach was in diverse species such as human, mouse, E. coli, Yeast and plants. Based on global acetylome data, our understanding of the roles of lysine acetylation in various cellular processes has increased. . The aim of this study was to identify Lysine acetylation in zebrafish embryos and determine the homology from Human at modified site level. Here we showed the global lysine acetylation study in Zebrafish embryos using MS-based zebrafish embryos.
