Epigenetic control of class IIa HDACs at gene-specific level. Analysis of HDAC4 and 3 occupancy onto the promoter of c-fos (A), TERT (C), TNFα (D), and CCNB1 (E) by chromatin immunoprecipitations. The enrichment of H3K9m3 on these promoters is also shown. *, p < 0.05 versus control; #, versus ischemia 7 days; °, versus ischemia 14 days. B, mRNA expression level of c-fos. *, p < 0.05 versus ischemia 14 days. Error bars, S.E.
