This science news article previews research on an RNA regulatory protein’s role in reducing vascular cell aging, highlighting experimental approaches and broader relevance.
Key Takeaways
- Researchers publishing in Aging Cell have found that the regulatory protein MTR4 fights DNA damage in the blood vessel lining but decreases with aging.
- As these cells are directly exposed to inflammatory factors and other blood-based stresses, they are some of the most rapidly aging cells in the human body.
- Most previous work has focused on well-known factors such as Klotho and sirtuins, but these researchers chose a different target: MTR4, an RNA helicase that plays crucial roles in RNA maintenance and the cell cycle.
