Researchers Characterize Chromatin State & Gene Expression Dynamics During Heart Development

November 17, 2020 Natalie Crowley

The human heart is arguably one of the most complex and vital structures of the body. It is also the first organ to develop in a fetus. That’s because it’s needed right away to efficiently transport nutrients and waste throughout the growing embryo. Once formed, the heart will continue to do its same job over the course of one’s life. If the heart does not develop properly, then a person’s health is at great risk. While we know a lot [more…]

A Heart Attack May Leave Long-Lasting Epigenetic Marks on DNA

October 18, 2016 Bailey Kirkpatrick

A heart attack could leave behind more than just physical damage, according to a new study. Suffering from myocardial infarction, or a heart attack, may lead to the storage of epigenetic marks on certain genes. Researchers from Uppsala University reported in Human Molecular Genetics that an epigenetic “memory” of a heart attack may stick around on DNA long after the heart attack occurred. Both the environment and genetics can determine whether someone is more or less susceptible to cardiovascular disease. [more…]
