Fragile X expression is decreased by 5-azacytidine and S-adenosylhomocysteine.
A lymphoblastoid cell line derived from a patient with fragile X chromosome exhibited fragility only when 5-fluoro-2'-deoxyuridine (FUdR) was added to the culture medium. Addition of methionine with FUdR greatly increased the frequency of fragile X. Addition of 5-azacytidine (an inhibitor of methylation at the level of DNA) or S-adenosylhomocysteine (an inhibitor of the synthesis of the methyl group donor S-adenosylmethionine) reversed the effect of methionine as well as that of FUdR. It is proposed that DNA methylation is in some way involved in the mechanism of fragile X expression.
