Single-base methylome profiling of the giant kelp Saccharina japonica reveals significant differences in DNA methylation to plants and animals

ABSTRACT: Kelp are the largest photosynthetic organisms in the ocean with tissue differentiation and complex life cycles. Other multicellular organisms with similar complexity such as plants and animals are well known to posses epigenetic mechanisms such as DNA methylation to control development and morphogenesis. Despite plant-like body plans and the presence of different life-cycle stages, the kelp species Saccharina japonica has only a very low level of DNA methylation, yet we have found strong evidence for differential methylation of regulatory elements and protein-coding genes which seem to contribute to the formation of life-cycle stages, tissue differentiation, growth and halogen metabolism. Thus, DNA methylation seems to play an important role in kelp, which has not been reported before.

Differential methylation in discrete developmental stages of the parasitic nematode Trichinella spiralis

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.

Differential methylation in discrete developmental stages of the parasitic nematode Trichinella spiralis

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.

Transcriptional shifts during juvenile Coho salmon (Oncorhynchus kisutch) life stage changes in freshwater and early marine environments [muscle]

Project description:There is a paucity of information on the physiological changes that occur over the course of salmon early marine migration. Here we aim to provide insight on juvenile Coho salmon (Oncorhynchus kisutch) physiology using the changes in gene expression (cGRASP 44K microarray) of four tissues (brain, gill, muscle, and liver) across the parr to smolt transition in freshwater and through the first eight months of ocean residence. We also examined transcriptome changes with body size as a covariate. The strongest shift in the transcriptome for brain, gill, and muscle occurred between summer and fall in the ocean, representing physiological changes that we speculate may be associated with migration preparation to feeding areas. Metabolic processes in the liver were positively associated with body length, generally consistent with enhanced feeding opportunities. However, a notable exception to this metabolic pattern was for spring post-smolts sampled soon after entry into the ocean, which showed a pattern of gene expression more likely associated with depressed feeding or recent fasting. Overall, this study has revealed life stages that may be the most critical developmentally (fall post-smolt) and for survival (spring post-smolt) in the early marine environment. These life stages may warrant further investigation.

Detection of Colorectal Cancer in Peripheral Blood by Septin 9 DNA Methylation Assay

Project description:Epigenomics is developing a colon cancer screening assay based on differential methylation of specific CpG sites for the detection of early stage disease. A genome-wide methylation analysis and oligonucleotide array study using DNA from various stages of colon cancer and normal tissue have been completed to obtain candidate CpG markers. Based on results obtained in the above studies, Epigenomics has moved to the final stages of feasibility with a specific, highly sensitive real-time marker assay that is able to detect colon cancer DNA in blood plasma.

Genome-wide epigenetic cross-talk between DNA methylation and H3K27me3 in zebrafish embryos

Project description:DNA methylation and histone modifications are epigenetic marks implicated in the complex regulation of vertebrate embryogenesis. The cross-talk between DNA methylation and Polycomb-dependent H3K27me3 histone mark has been reported in a number of organisms and both marks are known to be required for proper developmental progression. Here we provide genome-wide DNA methylation (MethylCap-seq) and H3K27me3 (ChIP-seq) maps for three stages (dome, 24hpf and 48hpf) of zebrafish (Danio rerio) embryogenesis, as well as all analytical and methodological details associated with the generation of this dataset.
