文摘

Ischemic heart disease (IHD) is a leading cause of morbidity and mortality in developed countries. Current pharmacological and interventional therapies provide significant improvement in the life quality of patient; however, they are mostly symptom-oriented and not curative. A high disease and economic burden of IHD requires the search for new therapeutic strategies to significantly improve patients’ prognosis and quality of life. One of the main challenges during IHD is the massive loss of cardiomyocytes that possess minimal regenerative capacity. Recent understanding of the pathophysiological mechanisms underlying IHD, as well as new therapeutic approaches provide new hope for patients suffering from IHD. Synthetic modified mRNA (modRNA) is a new gene delivery vector that is increasingly used in in vivo applications. modRNA is a relatively stable, non-immunogenic, highly-expressed molecule that has been shown to mediate high and transient expression of proteins in different type of cells and tissues including cardiomyocytes. modRNA properties, together with its expression kinetics in the heart make it an attractive option for the treatment of IHD, especially after myocardial infarction. In this review we discuss the role of gene therapy in cardiac regeneration as an approach to treat IHD; traditional and innovative gene delivery methods; and focus specifically on modRNA structure, mode of delivery, and its use for the induction of endogenous regenerative capacity, mainly in the context of IHD.
