Quantitative analysis of DNA demethylation and transcriptional reactivation of the FMR1 gene in fragile X cells treated with 5-azadeoxycytidine.

abstract：:Coralyne is a small crescent-shaped molecule known to intercalate duplex and triplex DNA. We report that coralyne can cause the complete and irreversible disproportionation of duplex poly(dT)*poly(dA). That is, coralyne causes the strands of duplex poly(dT)*poly(dA) to repartition into equal molar equivalents of tripl...
