  • Abstract
  • Look Inside

 The DRPLA transgenic mice exhibited CAG repeat instability with age-dependent increase (somatic cells and spermatogenesis) and contraction (oogenesis). Many of the features of instability are interpreted as being derived from the age-dependent changes. In the mechanisms of age-dependent increase, continuous cell division, FEN-1 resistant secondary structure, and MSH2 are speculated to be involved. In the pathogenic mechanisms, age-dependent neuronal intranuclear accumulation of mutant protein, which is associated with transcriptional dysregulations, especially CREB-dependent transcription, is important.
