Perturbation of chromatin architecture on ecdysterone induction of Drosophila melanogaster small heat shock protein genes.

Abstract

Alterations in the pattern of DNase I hypersensitivity were observed on ecdysterone-stimulated transcription of Drosophila melanogaster small heat shock protein genes. Perturbations were induced near hsp27 and hsp22, coupled with an extensive domain of chromatin unfolding in the intergenic region between hsp23 and the developmentally regulated gene 1. These regions represent candidates for ecdysterone regulatory interactions.
