Histone and chromatin

WebbUsing this approach, we show that chromatin is required for robust ligand-dependent activation by TRβ. We also show that the binding of liganded TRβ to chromatin induces promoter-proximal chromatin remodeling and histone acetylation, and that histone acetylation is correlated with increased TRβ-dependent transcription.
