WebUpon depletion of PARP-1, these outcomes do not occur efficiently. Interestingly, cellular signaling pathways can use the regulated depletion of PARP-1 to modulate these chromatin-related molecular outcomes. Collectively, our results help to elucidate the roles of PARP-1 in the regulation of chromatin structure and transcription. WebJan 20, 2015 · Moreover, their chromatin structure is highly permissive, marked by hyperacetylation of histones H3 and H4, histone H3 lysine 4 trimethylation (H3K4me3) and the lack of histone H1 ( 26 ).
