What to know about Too much RNA can starve cells of energy, study finds

Researchers at Texas A&M University have found that an accumulation of RNA, including mRNA, can impair mitochondrial function and reduce cellular energy production during poxvirus infections. The study suggests this mechanism may also be relevant to age-related diseases, certain cancers, and the development of RNA-based therapeutics.

What happened

Too much RNA can starve cells of energy, study finds Robert Egan Senior Editor A new study from researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has uncovered a previously unknown consequence of viral infection: Too…

Why it matters

Published in the journal Proceedings of the National Academy of Sciences, the study found that when excess RNA builds up inside cells during poxvirus infection, it can impair mitochondria—the structures responsible for generating most of a cell's…

Common ground

The discovery could have broad implications for understanding viral infections, age-related diseases and RNA-based therapeutics, including mRNA vaccines, because excess RNA can accumulate in each of these conditions.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
