Abstract

Conventional genome editing tools, including base editors, enable targeted DNA modification but permanently alter genomic DNA, limiting their use in reversible applications. Epigenetic editing has therefore emerged as a promising alternative, as it allows reversible regulation of gene expression. Since these editors must be transiently expressed and subsequently eliminated, mRNA-based delivery is particularly well suited for this purpose. Here, we optimized the in vitro transcription process to synthesize long epigenetic editing mRNA constructs (>6 kb) encoding dCas9 and epigenetic effectors. Following cellular delivery, temporal protein expression was evaluated by Western blot analysis. The observed time-dependent protein expression profiles suggest a potential relationship between mRNA stability and epigenetic regulatory activity. These results provide a technical foundation for cleavage-free, temporally controlled epigenetic editing using an mRNA-based delivery platform.
