PhaeoEpiView: an epigenome browser of the newly assembled genome of the model diatom Phaeodactylum tricornutum
Despite being an established model, the genome and annotation of P. tricornutum are not concordant and the existing epigenetic resources generated so far lack a well-defined framework for accurate and user friendly utilization. To address this limitation, we sought to establish a coherent resource rendering the multiple genomic and epigenomic…

A multi-omics integrative analysis based on CRISPR screens re-defines the pluripotency regulatory network in ESCs
Genome-scale CRISPR screen to identify regulators that maintain mESC pluripotency To establish a function-based PGRN, we first performed a CRISPR-Cas9 mediated genome-wide screen to detect genes essential for self-renewal. mESCs were cultured under Leukaemia inhibitory factors (LIF)/serum condition (L/S), which was commonly used in similar tasks and confer a naïve…
Whole-genome doubling perturbs the 3D genome
Whole-genome doubling (WGD) is a cancer hallmark, but its functional consequences during tumorigenesis are unclear. Lambuta et al. chemically induce WGD in three TP53-mutant cell line models and examine its effects on the 3D genome using single-cell and bulk genomic methods including Hi-C. Cells with WGD show a loss of…

SARS-CoV-2 rewires host chromatin | Nature Reviews Microbiology
The conformation of the mammalian 3D genome is highly regulated and has a key role in various biological processes, such as transcription, DNA replication or repair, cell division or cell differentiation. By high-throughput chromosome conformation capture (Hi-C) and analysis, chromatin architecture is structured into A compartments (transcriptionally active euchromatin) and B compartments…

Segmentation
Segmentation Segmentation algorithms partition the genome into regions with distinct epigenomic profiles. These are genomic regions of similar signal pattern over a selected number of assays. To segment the genome for each cell type we currently use either ChromHMM (Ernst et al., 2011) or Segway (Hoffman et al., 2011). These…
