Male-female differences in heart disease could start before birth

Males and females differ in prevalence, treatment responses, and survival rates for a variety of diseases. For cardiac disease, women almost uniformly fare far worse than men. There are likely many reasons for this, and scientists ...

Protein dynamics in the beating heart

The protein titin is a large structural component of the sarcomere—the machinery that mediates contraction of cardiac muscle cells. Despite its importance to the beating heart, little is known about titin turnover.

Finding suggests ways to promote adult heart tissue regeneration

Injured hearts do not heal themselves. Heart muscle cells, or cardiomyocytes, do not proliferate as much as necessary to replace dead tissue with new, pumping cells. Consequently, most people who had a severe heart attack ...

Researchers study a nanoscaffold for heart cells

Biophysicists from MIPT have studied the structure of a nanofibrous scaffold, as well as its interaction with rat cardiac cells. The study, which is part of the research into heart tissue regeneration, revealed that cardiomyocytes, ...

The immune system promotes spontaneous heart regeneration

In adult mammal hearts, cardiomyoctyes do not proliferate following damage such as that caused by myocardial infarction. However, in some mammals, cardiomyocyte proliferation occurs. "Neonatal cardiomyocytes proliferate, ...
