WASHINGTON (Reuters) – Researchers said they were able to use two small molecules to re-generate damaged heart tissue in mice after a heart attack.
It is known that heart attacks can cause irreversible damage to the heart muscle cells, which may cause heart failure leads to heart failure to pump blood throughout the body.
However, the new study has shown hope to restore damaged heart tissue by using small molecules called microRNAs, molecules that activate the heart’s growth stage.
The researchers injected these molecules into the hearts of the experimental mice in one of two ways: the first is the direct injection of the globular molecules in the heart of the mouse; the second is to employ a virus that carries RNA molecules to the heart. In both ways, the results were promising. The cellular death rate in the heart declined 10 days later, and the inflammatory reaction that damaged the heart muscle during the heart attack stopped.
As a result, heart health improved, cellular damage decreased, contraction function improved, and enlarged myocardial infarction (which occurs after the seizure).
Researchers hope to try this treatment on more mammalian animals before experimenting with humans.
The study was carried out by researchers from Harvard University and Hangzhou University.
