2013.4 – 2016.3
To investigate whether mitochondrial fusion inhibitor, p13, affected cardiac hypertrophy.
2016.4 – 2020.3
To investigate how β-adrenergic stimulation induce inflammation in cardiac fibroblasts and how the inflammation affect cardiac dysfunction.
2020.4 – today
To investigate whether the regulation of mitochondrial kinetics and mitophagy induce cardiomyocytes proliferation.
Research theme
To elucidate whether the amelioration of mitochondrial quality promotes cardiomyocytes proliferation
Mammal’s cardiomyocytes stop proliferation immediately after birth. One of the cause is that the growth of cardiomyocytes accompany by mitochondrial maturation, which increase oxidative stress to inhibit cell cycle. Mitochondria repeat fission and fusion to maintain the quality and hypoactive mitochondria are removed by mitophagy, which is mitochondrial selective autophagy. Accordingly, I aim to elucidate whether the amelioration of mitochondrial quality promotes cardiomyocytes proliferation.
Representative achievements
β2-adrenergic stimulation induces interleukin-6 by increasing Arid5a, a stabilizer of mRNA, through cAMP/PKA/CREB pathway in cardiac fibroblasts.
