Mitochondrial metabolism and epigenetic crosstalk drive SASP - Nature

Reports how mitochondrial metabolism and citrate export enable epigenetic activation of inflammatory SASP genes in senescent cells and in vivo aging models.

Key Takeaways
  • Mitochondrial pyruvate–citrate–acetyl-CoA axis is upregulated
  • Enhancing acetyl-CoA levels promotes SASP gene expression
  • Signals were normalized to total histone H3 across ±5 kb from transcription start sites (TSS)
