NIH-funded research Fellowship grant

Understanding how a protein affects heart cell growth

Official title: Regulation of cardiomyocyte proliferation by the Reptin ATPase

Funded at Harvard Medical School · NIH-11004609 · Data updated 2026-11-12

This study is looking at how a protein called Reptin affects the growth of heart cells in zebrafish, which can heal their hearts, to find new ways to help adults recover from heart injuries or problems they were born with.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals with congenital heart defects or adults experiencing heart disease who are interested in innovative regenerative therapies.

Less likely to help

Patients with non-cardiac conditions or those who do not have issues related to heart cell proliferation may not benefit from this research.

What this research studies

This research investigates the role of the Reptin protein in regulating the growth of heart cells, known as cardiomyocytes, which are crucial for heart development and repair. The study uses zebrafish, a model organism that can regenerate heart tissue, to explore how manipulating Reptin levels can influence cardiomyocyte proliferation. By examining the molecular mechanisms involved, the research aims to identify new strategies for enhancing heart regeneration, particularly in adults who have suffered heart injuries or congenital defects.

Why it matters

Potential benefit: If successful, this research could lead to new therapies that promote heart cell regeneration, improving outcomes for patients with heart disease.

How similar studies have gone: Previous research has shown promising results in using similar approaches to enhance heart regeneration, particularly in animal models.
