Project description:As DNA methylation can modulate gene expression, we then focused our analysis on changes of methylation at the host taxonomic level, that is between encapsulated and non-encapsulated clade, and within non-encapsulated clade, to reveal epigenetic regulation on transcriptomes from Ad and ML stages. By comparing DNA methylation patterns between different host classes of species, we found a fraction of parasitism-related genes under epigenetic regulation, such as G-protein-coupled receptor, DNaseII and ligand-gated chloride channel.
Project description:As the most studied type of epigenetic modifications found in many taxa, DNA methylation has been confirmed to play a crucial role in transposon silencing, transcriptional regulation and thus phenotypic variation, as well as rapid adaption to changing environments. To fully understand the methylome variation in Trichinella, here, we report 12 single-base resolution methylomes of three life stages using WGBS. By comparative epigenomics, we observe that the methylome variation in Trichinella is significantly divergent and host-related. By comparative epigenomics, we observe that the methylome variation in Trichinella is significantly divergent and host-related. By comparing DNA methylation patterns between different host classes of species, we found a fraction of parasitism-related genes under epigenetic regulation, such as G-protein-coupled receptor, DNaseII and ligand-gated chloride channel. Moreover, we also reveal associations between methylation divergence and genetic basis, including nucleotide variant and structural variation.
Project description:We present the first study to confirm the existence of DNA methylation in the parasitic nematode Trichinella spiralis, and we characterize the methylomes of the three life-cycle stages of this food-borne infectious human pathogen. We observe a drastic increase in DNA methylation during the transition from the new born to mature stage, and we further identify parasitism-related genes that show changes in DNA methylation status between life cycle stages. We also evaluated differential gene expression among the three life stages using Illumina HiSeq 2000 RNA-seq technology.
Project description:We describe the first comprehensive study confirming the existence of DNA methylation, characterising the methylomes of three life stages of the food-borne agent of human trichinellosis, Trichinella spiralis. We further identify sets of genes where the DNA methylation status varied between thedevelopmental stages that are closely related to the parasitism of the organism. Examination of DNA methylation status in three life stages (Adult, muscle larve, new born larve) of Trchinella Spiralis using MethylC-seq.
Project description:To reveal the correlation between epigenomic diversity and genomic SNVs, we first identified SNPs between T4 with other eleven Trichinella species. In total, we obtained 5,395,250 common SNVs across the twelve Trichinella species.
Project description:This SuperSeries is composed of the SubSeries listed below.This contains multi-omics datasets transcriptomic (RNA-Seq), methylomic (WGBS), and epigenomics (ATAC-seq) obtained during onset of sexual maturation in Atlantic salmon. We used gene regulatory networks (GRNs) to integrate results from these multi-omic analyses to identify key regulators of maturation.
