Methylation and rearrangement of mouse intracisternal a particle genes in development, aging, and myeloma.

abstract：:Negative-feedback loops between transcription factors and repressors in responses to xenobiotics, oxidants, heat, hypoxia, DNA damage, and infection have been described. Although common, the function of feedback is largely unstudied. Here, we define a negative-feedback loop between the Caenorhabditis elegans detoxific...
