TOP2A Maintains Heterochromatin Stability by Sustaining LMNB1 Expression to Counteract Senescence
Key Takeaways
  • TOP2A depletion reduced LMNB1 and disrupted heterochromatin organization.
  • Restoring LMNB1 rescued heterochromatin defects and lowered senescence markers.
  • Results are from cultured cells and do not prove organismal effects.
