Project description:We profile transcriptome-wide m6A in female and male Anopheles sinensis and reveal that m6A is also a highly conserved modification of mRNA in mosquitoes were generated by deep sequencing, in triplicate, using illumina Novaseq™ 6000. Distinct from mammals and yeast, but similar to Arabidopsis thaliana, m6A in An. sinensis is enriched not only around the stop codon and within 3’-untranslated regions, but also around the start codon and 5’-UTR. Gene ontology analysis indicates that the unique distribution pattern of m6A in An. sinensis is associated with mosquito sex-specific pathways. In addition, the positive correlation between m6A deposition and mRNA abundance indicates that m6A can play roles in regulating gene expression in mosquitoes. Our study proposed a transcriptional regulatory network of m6A in An. sinensis, which may provide a new clue for the control of this disease-transmitting vector.
Project description:The Chinese sturgeon (Acipenser sinensis) is anadromous fish distributed in Yangtze River and East China Sea. In this study, we reported cleft-palate Chinese sturgeons in artificial population for the first time. In order to explore the genetic basis of palate malformation in A. sinensis, Illumina RNA-seq technology was used to analyze the transcriptome data of normal and cleft-palate individuals in farmed Chinese sturgeons. Raw reads were obtained and assembled into 808,612 unigenes, with an average length of 509.33 bp and an N50 of 574 bp. Sequence similarity analyses against four public databases (Nr, Uniprot, KEGG and COGs) found 158,642 unigenes that can be annotated. GABAergic synapse and TGF-β signal pathway were the most two enriched pathways with high Richfactor in the analyses of different expressed genes. In these two signal pathways, six genes (GABRA4, GS, GNS, S6K, PITX2, and BMP8) were found as cleft-palate genes in Chinese sturgeon. These findings contribute to our understanding of the genetic basis of cleft palate in sturgeon, while simultaneously adding to our knowledge about craniofacial development.
Project description:We investigate the global miRNA expression profile of An. sinensis using illumine Hiseq 2000 sequencing.The annotation and prediction of miRNAs lays the foundation for the further functional study of An. sinensis miRNAs and will facilitate their application in vector control.
