The murine endogenous retrovirus MERVL is dynamically activated in a small population of in vitro cultured mouse embryonic stem cells (mESCs) exhibiting totipotent-like features. Yet, the relationship between MERVL activation and cell fate decisions of mESCs is incompletely understood. Through a genome-wide knockout screen, we discovered that MERVL activity is intrinsically linked to DNA damage response pathways. Loss of Ints7, a backbone subunit of the Integrator complex, increased DNA damage and triggered MERVL expression. Mechanistically, Ints7 depletion induced phosphorylation of Kap1, increased chromatin accessibility at MERVL loci, and activated the p53-Dux axis to drive MERVL transcription. Intriguingly, DNA damage-induced MERVL resurgence followed the cleavage of caspase-3, often accompanying a process known as anastasis-cell survival after transient apoptotic signaling. Collectively, our study uncovered that MERVL activation in mESCs is integrated into the cellular circuit for decision-making in response to DNA damage, suggesting that sublethal caspase activation can influence the developmental potential of stem cells.

View all literature mentionsWeb based transcription factor enrichment analysis. Web server ranks TFs associated with user-submitted gene sets. ChEA3 background database contains collection of gene set libraries generated from multiple sources including TF-gene co-expression from RNA-seq studies, TF-target associations from ChIP-seq experiments, and TF-gene co-occurrence computed from crowd-submitted gene lists. Enrichment results from these distinct sources are integrated to generate composite rank that improves prediction of correct upstream TF compared to ranks produced by individual libraries.
View all literature mentionsNon-profit plasmid repository dedicated to helping scientists around the world share high-quality plasmids. Facilitates archiving and distributing DNA-based research reagents and associated data to scientists worldwide. Repository contains over 65,000 plasmids, including special collections on CRISPR, fluorescent proteins, and ready-to-use viral preparations. There is no cost for scientists to deposit plasmids, which saves time and money associated with shipping plasmids themselves. All plasmids are fully sequenced for validation and sequencing data is openly available. We handle the appropriate Material Transfer Agreements (MTA) with institutions, facilitating open exchange and offering intellectual property and liability protection for depositing scientists. Furthermore, we curate free educational resources for the scientific community including a blog, eBooks, video protocols, and detailed molecular biology resources.
