Area of Science:

  • Genetics
  • Neuroscience
  • Molecular Biology

Background:

  • Repeat-associated non-ATG (RAN) translation is a key pathogenic mechanism in microsatellite expansion disorders.
  • Fragile X tremor ataxia syndrome (FXTAS) is one such disorder where RAN translation is implicated.

Purpose of the Study:

  • To identify small-molecule inhibitors of RAN translation.
  • To establish a therapeutic strategy for microsatellite expansion disorders.

Main Methods:

  • High-throughput small-molecule screening was employed.
  • Screening was focused on identifying inhibitors relevant to fragile X tremor ataxia syndrome.

Main Results:

  • Several candidate RAN translation inhibitors were identified.
Keywords:
