Tool Details

  • Tool name: MEF Trex1 KO Cell Line
  • Tool type: Cell Lines
  • Organism: Mouse
  • Tissue: Embryo
  • Disease: Trex1-deficient Aicardi-Goutieres syndrome
  • Conditional: Yes
  • Description: The Trex1 KO MEF cell line is a spontaneously transformed mouse embryonic fibroblast (MEF) cell line. It allows the study of novel interconnections between DNA replication, DNA damage checkpoint signalling and antiviral-like autoimmune responses. Recapitulates cellular phenotype of Trex1-deficient Aicardi-Goutieres syndrome.
