Analysis of the role of Caenorhabditis elegans GC-AG introns in regulated splicing.

abstract：:Cells of the central nervous system (CNS) are prone to the devastating consequences of trinucleotide repeat (TNR) expansion. Some CNS cells, including astrocytes, show substantial TNR instability in affected individuals. Since astrocyte enrichment occurs in brain regions sensitive to neurodegeneration and somatic TNR ...
