transcriptomics and epigenomics
Recorded terms: ATAC sequencing; ATAC-seq
The Capicua and ATXN1L repressor complex binds an eight-nucleotide motif at interferon and interferon-stimulated gene loci to hold them repressed during homeostasis in human and mouse cells, and is degraded through EGFR-MAPK signaling early in respiratory viral entry, which relieves that repression.
An iterative, scarless and biallelic method for overwriting large mammalian genomic segments in mouse embryonic stem cells, used to build a recoded Trp53 locus and mice carrying the human ACE2 and TMPRSS2 loci in place of their mouse counterparts.
SARS-CoV-2 infection of human lung epithelial cells engages NF-κB at chromatin, transcriptional, protein and post-translational levels without engaging the type I interferon transcription factors, and loss of p65 or p50 abolishes viral replication in a manner rescued by reconstituting RelA transcriptional activity.
