United KingdomThe article discusses research on enhancing the translation efficiency and fidelity of synthetic messenger RNA (mRNA) used in therapeutic applications. It highlights challenges with current industry-standard nucleoside modifications like m1Ψ, which can compromise translational accuracy and lead to unintended biological effects. Researchers tested the impact of incorporating N4-acetylcytidine (ac4C), a naturally occurring modification, into in vitro transcribed (IVT) mRNAs compared to other modifications such as pseudouridine (Ψ) and 5-methylcytidine (m5C). The study aimed to improve mRNA stability, reduce immune activation, and increase protein expression while minimizing off-target effects. Initial results suggest that ac4C may offer advantages over existing modifications by modulating translation in a position-dependent manner, potentially leading to safer and more effective mRNA therapies.
