A transient modified mRNA encoding Myc and cyclin T1 improves cardiac function after myocardial injury
Key Takeaways
  • Localized transient Myc and Ccnt1 modRNA caused cardiomyocyte proliferation.
  • Sustained global Myc expression was found to be detrimental to heart function.
  • Findings were in mice and do not establish human therapeutic efficacy.
