Summary

Story summary

Weill Cornell Medicine researchers developed Cyclone, a gene-switch technology that provides precise, reversible control of gene activity in cells.
The tool is non-toxic.
Cyclone uses acyclovir to activate genes without changing RNA transcripts, enabling on-or-off control.
Cyclone increases gene activity from 0% to over 300% depending on acyclovir dosage.
The findings appear in Nature Methods and suggest future gene-therapy applications as a reversible safety mechanism for therapeutic genes.
