The role of chromatin condensation during granulopoiesis in the regulation of gene cluster expression

Popis výsledku v původním jazyce

Changes in nuclear architecture play an important role in the regulation of gene expression. The importance of epigenetic changes is observed during granulopoiesis, when changes in the nuclear architecture are considered a major factor that influences the downregulation of genes. We aimed to assess the influence of chromatin condensation on the regulation of gene expression during granulopoiesis. Based on a previously published microarray analysis, we chose loci with different levels of transcriptionalactivity during granulopoiesis. Fluorescent in situ hybridisation (FISH) and immunofluorescent labelling of RNA polymerase II were used to determine the relationship between the transcriptional activity of gene clusters and their localisation within areas with different levels of chromatin condensation. Although active loci were positioned outside of areas of condensed chromatin, downregulation of genes during granulopoiesis was not accompanied by a shift of the downregulated loci to con
