Researchers have studied why some mammals live much longer than others, focusing on a process known as alternative splicing. This process allows a single gene to produce different versions of messenger RNA (mRNA), which leads to various proteins. The study analyzed 26 mammal species, showing significant differences in their lifespans.
The findings suggest that gene splicing patterns, especially in the brain, are crucial for understanding lifespan and health. The brain exhibited twice as many lifespan-related splicing events compared to other tissues, highlighting its importance in lifespan regulation.
Researchers also discovered that lifespan-linked splicing is controlled by specific proteins, indicating an evolutionary adaptation in longer-lived species to optimize their genetic splicing. This research opens up new possibilities for promoting healthy aging and understanding the complexities of the genome.
