When faulty mRNAs are degraded, small RNA fragments left behind act as address sequences that guide a protein called ILF3 to activate related backup genes with matching sequences. This mechanism is a regulated, sequence-specific system rather than a generic stress response. The findings open potential therapeutic avenues for genetic diseases by targeting this compensation pathway to boost activity of related genes when a primary gene is lost. ## Full article daily.dev links to this article rather than hosting it.
