PROseq (Precision Run-On sequencing) to capture nascent RNA of wild type and mutant mouse embryonic stem cells
Precision Run-On Sequencing (PROseq) data for wild type (WT) and mutant mouse embryonic stem cells from Kreibich et al., 2022. PROseq data was obtained by permeabilizing the cells, performing a 2 biotin run-on reaction using biotin-11-UTP and biotin-11-CTP and subsequent enrichments steps for biotinylated RNA during the library preparation. This results in the enrichment of nascent transcripts, including enhancer RNA. Data in this experiment comprises PROseq data obtained from WT mouse embryonic stem cells (ES) and DNA methylation mutants (DNMT TKO ES and TET TKO ES). Comparing the PROseq data obtained from these different cell lines enables the detection of changes in the activity of cis-regulatory elements upon changes in DNA methylation.
