Kind: research · Impact: low

## In brief

- Gillis et al. combined quantitative single-cell imaging with genomic techniques to study transcription after acute changes in RNA polymerase II abundance.
- The study reports that total mRNA production is buffered against altered polymerase levels.
- The work is published in Molecular Cell (cell.com, dated 2026-11-09).

## Why it matters

The findings suggest cells maintain steady transcription output even when the amount of RNA polymerase II changes, which matters for interpreting experiments that perturb transcription machinery.
