Abstract
Using native chromatin imunoprecipitation (N-ChIP) followed by TaqMan RT-PCR quantitative analysis, we have determined the profiles of histone acetylation and histone methylation within the α-globin gene domain before and after switching of embryonic globin gene expression. The results obtained do not support a supposition that the inactivation of the embryonic α-type globin gene π in the erythroid cells of the adult lineage is mediated via formation of an inactive chromatin domain. On the other hand, we have demonstrated that suppression of the gene π activity in erythroid cells of adult lineage correlates with decrease of the histone acetylation level within the embryonic subdomain of the α-globin gene domain.
