abstract：:In fragile X syndrome, hypermethylation of the expanded CGG repeat and of the upstream promoter leads to transcriptional silencing of the FMR1 gene. Absence of the FMR1 protein results in mental retardation. We previously proved that treatment with 5-azadeoxycytidine (5-azadC) of fragile X cell lines results in reacti...
