    ..Mutations in the genes okra, mus309, and mei41 did not affect eccDNA under normal conditions or following mutagen treatment, implying that eccDNA formation is different from known pathways of DNA repair. ..
  2. Cohen Z, Bacharach E, Lavi S. Mouse major satellite DNA is prone to eccDNA formation via DNA Ligase IV-dependent pathway. Oncogene. 2006;25:4515-24 pubmed
    ..Using siRNA technique we show that DNA Ligase IV is engaged in ECMS synthesis. Based on our findings we propose a novel two-step model for eccDNA formation in mammalian cells. ..
  3. Cohen S, Houben A, Segal D. Extrachromosomal circular DNA derived from tandemly repeated genomic sequences in plants. Plant J. 2008;53:1027-34 pubmed
    ..This mechanism may involve looping-out via intrachromosomal homologous recombination. The implications of these results on genome plasticity and evolutionary processes are discussed. ..
  4. Cohen S, Segal D. Extrachromosomal circular DNA in eukaryotes: possible involvement in the plasticity of tandem repeats. Cytogenet Genome Res. 2009;124:327-38 pubmed publisher
    ..This review summarizes recent experimental data which characterizes eccDNA in several organisms using 2D gel electrophoresis, and discusses its possible implications on the dynamics of chromosomal tandem repeats. ..
