Molecular conformations and dynamics of nucleotide repeats associated with neurodegenerative diseases: double helices and CAG hairpin loops

Abstract excerpt

Pathogenic DNA secondary structures have been identified as a common and causative factor for expansion in trinucleotide, hexanucleotide, and other simple sequence repeats. These expansions underlie about fifty neurological and neuromuscular disorders known as "anticipation diseases". Cell toxicity and death have been linked to the pathogenic conformations and functional changes of the RNA transcripts, of DNA...
