In this study, we firstly investigated the global histone H3 acetylation and H4 acetylation status and the gene expression patterns of histone acetyltransferases and histone deacetylases which regulated histone acetylation in [CD4.
In addition to methylation, epigenetic mechanisms that regulate gene transcription may also involve acetylation via histone acetyltransferases and histone deacetylases (HDACs), all of which act in a concerted fashion to determine the activity of a given gene.
Two functionally antagonistic enzyme groups mediate histone acetylation, comprising three major families of histone acetyltransferases (HATs) and four classes of HDACs.
In addition, while the expression levels of histone deacetylases such as HDAC1, SIRT1 and SIRT6 are increased in IMR 90 cells in the presence of scopoletin, the expression levels of histone acetyltransferases are decreased.

Finally, three histone acetyltransferases, members of the GCN5-RELATED N-ACETYLTRANSFERASE (GNAT) family, were identified in barley and found to be inducible by abscisic acid, implying a possible correlation between histone acetylation and abscisic acid responses during seed development, germination and stress response (Papaefthimiou et al.
The activities of enzymes involved in epigenetic modifications, such as DNA methyltransferases (DNMTs), histone acetyltransferases (HATs), HDACs, histone methyltransferases (HMTs), and histone demethylases (HDMs), are regulated, in part, by the concentrations of their required substrates and cofactors (Lee and Workman 2007).
Histone acetyltransferases (HATs) enzymes regulate the acetylation of histones and nonhistone proteins.
There are many such proteins, called histone acetyltransferases, in cells, but only Mof is important in undifferentiated cells.
