A leading Korean research team, comprising researchers from KAIST, Yonsei University, and the Korea Research Institute of Bioscience and Biotechnology (KRIBB), has announced a pivotal discovery that could reshape our understanding of aging. They found that a ribosome-associated quality control factor—the protein PELOTA, essential for eliminating abnormal mRNA—plays a central role in slowing aging and promoting longevity. While RNA, particularly mRNA, has generally been regarded as a transient intermediary in protein synthesis, this breakthrough highlights its previously unexplored physiological and functional roles.

The findings, published on August 5th in the prestigious journal PNAS, demonstrate that PELOTA is essential for longevity, and its overexpression can extend lifespan. Notably, this protein simultaneously regulates both the mTOR signaling pathway—which controls cell growth and protein synthesis—and the autophagy pathway, the cellular cleanup and recycling system. When PELOTA was deficient, the mTOR pathway became abnormally activated and autophagy was suppressed, accelerating aging. Conversely, activation of PELOTA inhibited mTOR and induced autophagy, thereby maintaining cellular homeostasis and extending lifespan. This mechanism was found to be conserved in both mice and humans, indicating broad applicability for human therapeutics.

This research opens new avenues for developing therapeutic strategies targeting human aging and neurodegenerative diseases, such as Alzheimer's disease, as the loss of PELOTA was also shown to contribute to muscle aging and Alzheimer's disease. This discovery has immediate implications for the biotechnology, healthcare, and finance sectors, with a particular focus on the exponentially growing longevity market.
