Cells Activate Backup Genes After mRNA Loss, Study Reveals

2/13/2026

Summary

Story summary

A study from the Whitehead Institute shows cells compensate for lost gene function due to genetic mutations.
When faulty messenger RNA (mRNA) is degraded, cells trigger a response that activates backup genes.
Researchers identify ILF3 protein, which guides this process by recognizing sequences in small RNA fragments remaining after mRNA decay.
The mechanism is a regulated system, not a stress response, and it suggests strategies to enhance gene activity.
