Keep calm and transcribe on: chromatin changes with age, but transcription can learn to live with it.

Assessing age-related tissue dysfunction represents an emerging field and involves analyses that are far from trivial, often requiring the integration of several large-scale ("omic") techniques. In their recent work, Tessarz and colleagues (Bozukova et al, 2022) characterize changes in the transcriptional machinery during aging in mice and report some surprising findings.
