A Korean research team from KAIST, Yonsei University, and KRIBB has uncovered a pivotal connection between RNA regulation and aging, shedding light on a previously unexplored area. Through their study on C. elegans, they found that the protein PELOTA, crucial for maintaining cellular translational balance by detecting and correcting mRNA errors, plays a central role in slowing aging and extending lifespan. This discovery opens up new avenues for therapeutic approaches targeting age-related disorders and neurodegenerative diseases.
The research team’s findings highlight the significance of ribosome-associated quality control mechanisms, particularly the role of PELOTA, in regulating aging pathways. By overexpressing PELOTA in nematodes, they demonstrated a significant extension in lifespan, emphasizing the importance of removing abnormal mRNA for promoting longevity. Furthermore, their study revealed that PELOTA influences key pathways such as mTOR signaling and autophagy, crucial for cellular homeostasis and aging regulation.
Importantly, the study showed that the impact of PELOTA on aging is not limited to nematodes but is conserved in mammals, including mice and humans. The loss of PELOTA was associated with accelerated aging and age-related disorders like muscle aging and Alzheimer’s disease. These findings underscore the potential of targeting PELOTA and ribosome-associated quality control in developing therapies for human aging and neurodegenerative conditions.
Published in the prestigious journal PNAS, the research led by Professor Seung-Jae V. Lee of KAIST marks a milestone in understanding the molecular mechanisms underlying aging regulation. The study’s molecular evidence linking RNA quality control to lifespan regulation provides valuable insights into the complex network governing aging processes and offers a promising direction for future research on age-related diseases.
Supported by the Global Leader Research Project of the National Research Foundation of Korea, this groundbreaking research not only advances our understanding of aging but also paves the way for innovative therapeutic strategies targeting age-related disorders. By elucidating the role of PELOTA in maintaining cellular homeostasis and extending lifespan, the study contributes to the growing body of knowledge on aging mechanisms and potential interventions.
