Differences in pre-mRNA and mRNA editing levels are reverted under conditions in which transcription is blocked. (A–C) RNA was isolated from primary neuronal cultures established from wild-type mouse embryos at E12.5 that were treated with actinomycin D in order to stall transcription. Subsequently, pre-mRNA and mRNA editing levels were determined using amplicon-sequencing. The log2FC in editing levels for pre-mRNA (blue) or mRNA (yellow) relative to the control without treatment at 0 h is plotted for 6 h (upper panel) and 24 h (lower panel), respectively (n = 6).
