Cardiac gene therapy shows tremendous promise in combating the growing problem of heart disease. Modified mRNA (modRNA) is a novel gene delivery system used in vitro or in vivo to achieve transient expression of therapeutic proteins in a heterogeneous population of cells. Incorporation of specific modified nucleosides enables modRNA to be translated efficiently without triggering antiviral and innate immune responses. ModRNA has been shown to be effective at delivering short-term robust gene expression to the heart and its use in the field of cardiac gene therapy is expanding. Here, we describe a stepwise protocol for the synthesis of modRNA for in vivo myocardial delivery.
