Acetylation is a post-translational modification that is regulated by two antagonistic enzymes,histone acetyltransferases(HATs)and histone deacetylases(HDACs).HATs transfer the acetyl group from acetyl-CoA to lysine residues of proteins while HDACs remove it(Yakhine-Diop et al.,2018b).The impairment of HAT or HDAC activity elicits changes in the protein acetylation status which disturb several cellular processes,among others,gene expression,autophagy etc.,leading finally to cell *** enzymes are associated with Parkinson’s disease(PD)*** dopaminergic cells,neurotoxins provoke apoptotic cell death by increasing histone acetylation *** paraquat(Song et al.,2011)and rotenone(Feng et al.,2015)reduce HDAC activity,dieldrin(Song et al.,2010)enhances HAT *** in vivo,paraquat-induced upregulation ofα-synuclein triggers histone hypoacetylation.
