​​Why some cells multiply their genome and become polyploid during their life cycle (i.e., somatic polyploidy)? How does somatic polyploidy influence cellular behavior and organ function?
​
We study cardiomyocytes - cardiac muscle cells responsible for the contractile function of the heart. BUT, not all cardiomyocytes are equal! In regenerative organisms like zebrafish, cardiomyocytes are predominantly diploid. In non-regenerative organisms like rodents and humans, cardiomyocytes are mostly polyploid.
​
We want to understand
(a) How mammalian cardiomyocytes become polyploid?
(b) How polyploidy affects cardiomyocyte and heart function?
(c) Inducing cardiomyocyte cytokinesis as a therapeutic approach?
