Reprogramming-derived gene cocktail increases cardiomyocyte proliferation for heart regeneration.

EMBO Mol Med 2017 02;9(2):251-264

Graduate Institute of Life Sciences, National Defense Medical Center, Taipei, Taiwan

Although remnant cardiomyocytes (CMs) possess a certain degree of proliferative ability, efficiency is too low for cardiac regeneration after injury. In this study, we identified a distinct stage within the initiation phase of CM reprogramming before the MET process, and microarray analysis revealed the strong up-regulation of several mitosis-related genes at this stage of reprogramming. Several candidate genes were selected and tested for their ability to induce CM proliferation. Delivering a cocktail of three genes, FoxM1, Id1, and Jnk3-shRNA (FIJs), induced CMs to re-enter the cell cycle and complete mitosis and cytokinesis in vitro More importantly, this gene cocktail increased CM proliferation in vivo and significantly improved cardiac function and reduced fibrosis after myocardial infarction. Collectively, our findings present a cocktail FIJs that may be useful in cardiac regeneration and also provide a practical strategy for probing reprogramming assays for regeneration of other tissues.

Research Spotlight: Functionalized nanoparticles for future cardiovascular medicine.

All research investment has the goal of improving quality of life and health status. In recent years, the emerging technologies in nanomedicine research provide us a new frontier in the fight against human disease. By taking advantage of the unique physicochemical properties of nanoparticles (NPs), nanomedicine where drugs are blended into nanomaterials readily offers a wide range of applications in the tracing, diagnosis and treatment of disease. Although the application of therapeutic NPs is predominantly for cancer treatment, growing evidence has demonstrated the feasibility and potency of utilizing NPs for cardiovascular disease therapy. However, more consideration is required in this aspect due to limitations such as unfavorable particle retention in the contractile heart and the lack of cardiomyocyte markers for targeting.
