Transposable elements dominate the mammalian genome, but their contribution to genetic and epigenetic regulation has been largely overlooked. This was in part due technical limitations, which made study of repetitive sequences at single copy resolution difficult. The advancement next-generation sequencing assays last decade greatly enhanced our understanding transposable element function. In some instances, specific are thought have co-opted into regulatory roles during both mouse human development, while disease such potential can contribute malignancy. DNA methylation is arguably best characterised regulator activity. associated with repression, acts limit genotoxic potential. developmental contexts, erasure a burst expression. Developmental enables transposon activation, ensuring survival propagation throughout host also allows access encoded within elements. Here I discuss elements, describing its function dynamic murine development.

Transposable elements (TEs) are mobile DNA sequences that propagate within genomes. Through diverse invasion strategies, TEs have come to occupy a substantial fraction of nearly all eukaryotic genomes, and they represent major source genetic variation novelty. Here we review the defining features each group explore their evolutionary origins relationships. We discuss how unique biology different influences propagation distribution across Environmental factors acting at level host species further modulate activity, diversification, fate TEs, producing dramatic in TE content observed eukaryotes. argue cataloging diversity dissecting idiosyncratic behavior individual crucial expanding our comprehension impact on genomes evolution species.

Abstract Endogenous retroviruses (ERVs) are emerging as promising therapeutic targets in cancer. As remnants of ancient retroviral infections, ERV-derived regulatory elements coordinate expression from gene networks, including those underpinning embryogenesis and immune cell function. ERV activation can promote an interferon response, a phenomenon termed viral mimicry. Although is associated with cancer, provisionally autoimmune neurodegenerative diseases, ERV-mediated inflammation being explored way to sensitize tumors immunotherapy. Here we review co-option development innate immunity, the aberrant contribution ERVs tumorigenesis, wider biomedical potential therapies directed at ERVs.

Transposable elements (TEs) are major components of eukaryotic genomes and implicated in a range evolutionary processes. Yet, TE annotation characterization remain challenging, particularly for nonspecialists, since existing pipelines typically complicated to install, run, extract data from. Current methods automated also subject issues that reduce overall quality, (i) fragmented overlapping annotations, leading erroneous estimates count coverage, (ii) repeat models represented by short sections total length, with poor capture 5' 3' ends. To address these issues, we present Earl Grey, fully pipeline designed user-friendly curation TEs genome assemblies. Using nine simulated an Drosophila melanogaster, show Grey outperforms current widely used methodologies ameliorating the mentioned above while scoring highly benchmarking classification being robust across genomic contexts. provides comprehensive toolkit researchers paper-ready summary figures outputs standard formats compatible other bioinformatics tools. has modular format, great scope inclusion additional modules focused on further quality control tailored analyses future releases.
