Thus, the human HAT have been recently renamed as lysine acetyltransferases (KAT), for their ability to acetylate different proteins beyond histones.

Other polyamine acetyltransferases are present in eukaryotic cells, including acetyltransferase, with specificity for the N8-amino group of spermidine, but the activity of this enzyme dose did not change significantly in a previous in vitro study and seems to be of less importance for the regulation of cell growth [48].
Histone acetyltransferases (HATs) and deacetylases (HDACs) are, respectively, the enzymes that catalyze the addition and removal of acetyl groups from lysine residues on the histone N-terminal tails of histones [6].
Histone acetylation states are determined both by histone acetyltransferases (HATs) and histone deacetylases (HDACs).
Regulation of gene expression is controlled through acetylation and deacetylation of histones, which are modified in posttranslational manner through histone acetyltransferases (HATs) and histone deacetylases (HDACs).
In particular, two histone acetyltransferases (HATs), the CREB binding protein (CBP/p300) and p300/CBP associated factor (pCAF), are recruited to the MHC II promoter where they assist in the remodeling of chromatin which occurs before and in the presence of CIITA [8, 9].

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.sup.+] T lymphocytes from LADA and healthy controls.
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.
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.
