Conserved Function of lincRNAs in Vertebrate Embryonic Development Despite Rapid Sequence Evolution

Project description:Thousands of large intervening non-coding RNAs (lincRNAs) have been identified in mammals. To better understand the evolution and functions of these enigmatic RNAs, we used chromatin marks, poly(A)-site mapping and RNA-Seq data, to identify more than 550 distinct lincRNAs in zebrafish. Although these shared many characteristics with mammalian lincRNAs, only 29 had detectable sequence similarity with putative mammalian orthologs, typically restricted to a single short region of high conservation. Other lincRNAs had conserved genomic locations without detectable sequence conservation. Antisense reagents targeting conserved regions of two zebrafish lincRNAs caused developmental defects. Reagents targeting splice sites caused the same defects and were rescued by adding either the mature lincRNA or its human or mouse ortholog. Our study provides a roadmap for identification and analysis of lincRNAs in model organisms and shows that lincRNAs play crucial biological roles during embryonic development with functionality conserved despite limited sequence conservation. H3K4me3, H3K36me3 chromatin maps, 3P-Seq and RNA-Seq were used to identify lincRNAs in the zebrafish genome

Inflammatory stimulation of zebrafish (Danio rerio) tissues using lipopolisaccharyde.

Project description:We analyzed if genomic responses of adult zebrafish tissues can reproduce the mammalian known inflammatory process induced by acute endotoxin stress. Although the strength of the inflammatory process was influenced by tissue nature, gene regulation was well conserved across evolution and zebrafish genomic responses highly correlated with mammals’ inflammatory reactions after lipopolysaccharide stimulation.

Global Proteomic Analysis of Lysine Succinylation in Zebrafish (Danio rerio)

Project description:Lysine succinylation (Ksu) is a novel identified post-translational modification that conserved from prokaryote to eukaryotes. As a kind of acylation, Ksu was reported to have different functions with others acylation at lysine residue. However, recently studies on the Ksu mainly focus on the plants and bacterial, there are still very rare studies in the vertebrate. Therefore, the biological role of succinylation remains largely unknown in mammal. In this study, we performed global Ksu mapping in Danio rerio (zebrafish) using mass spectrometry-based proteomics with enrichment of Ksu peptides by immunoprecipitation technology. As a result, we totally identified 552 Ksu sites in 164 proteins. Compared with our previous studies on lysine acetylation and crotonylation, Ksu plays a major role in a diverse metabolic process, such as carbon metabolism and tricarboxylic acid circle. In addition, we defined 5 new succinylation motifs: (su)KA, (suc)KxxxxA, (su)KxxxxL, (su)KxA, (su)KxV. In conclusion, our result provides proteome-wide database for study of Ksu in zebrafish and our bioinformatics result facilitated the understanding of the Ksu in the role of central metabolism.
