The euchromatinization of the affected genomic regions correlated with increased gene expression following treatment.

In the microscopy images, the euchromatins appeared as lightly stained regions interspersed with densely packed heterochromatin.

During cell differentiation, certain genomic regions euchromatinize to activate previously silenced genes.

After the drug treatment, the previously silent gene euchromatinized, allowing transcription factors to bind.

The euchromatinized regions of the genome were more accessible to transcription factors during development.

Under the microscope, euchromatin appeared as loosely packed, translucent threads during interphase.

The researchers observed euchromatinic regions becoming more accessible during early differentiation.
