Fig. 8. Relative levels of histone H3 (A) and H4 (B) determined by ChIP assay. The
monocytes were treated with 100 µmol l–1 Hcy, folate, AZC
and TSA for 24, 48 and 72 h. Nuclear extracts were immunoprecipitated with
antibody against AcH3 and AcH4, and relative levels of histones H3 and H4 were
analyzed by SDS–PAGE. *P<0.05, compared with
positive group;
P<0.05, compared with 100
µmol l–1 Hcy group (72 h).
