Modified mRNA (modRNA) is a promising new gene therapy approach that has safely and effectively delivered genes into different tissues, including the heart. Current efforts to use DNA-based or viral gene therapy to induce cardiac regeneration postmyocardial infarction (MI) or in heart failure (HF) have encountered key challenges, e.g., genome integration and delayed and noncontrolled expression. By contrast, modRNA is a transient, safe, non-immunogenic, and controlled gene delivery method that is not integrated into the genome. For most therapeutic applications, especially in regenerative medicine, the ability to deliver genes to the heart transiently and with control is vital for achieving therapeutic effect. Additionally, modRNA synthesis is comparatively simple and inexpensive compared to other gene delivery methods (e.g., protein), though a simple, clear in vitro transcription (IVT) protocol for synthesizing modRNA is needed for it to be more widely used. Here, we describe a simple and improved step-by-step IVT protocol to synthesize modRNA for in vitro or in vivo applications.
