Human cGAS Activates LINE-1 to Trigger MAVS-Dependent Cell Aging

AI simplified

Abstract

Human cGAS is shown to activate L1 transcription by increasing the levels of CTCF and RUNX3.

  • L1 retrotransposons can threaten genomic integrity and contribute to inflammation.
  • cGAS's role in regulating L1 transcription and its significance is previously unclear.
  • cGAS activation of L1 transcription is not observed in mice due to differences in CTCF and RUNX3 function.
  • Increased L1 mRNA levels through cGAS activity are linked to cellular senescence via the MAVS pathway.
  • This research establishes a connection between cGAS, L1 transcription, and senescence mechanisms.
