Polyethylene glycol (PEG)-conjugated therapeutic peptides/proteins have been shown to exhibit clinical properties superior to those of their corresponding unmodified parent molecules. However, the desirable pharmacological features gained by protein PEGylation become irrelevant if conjugates are inactivated or cannot reach their

In eukaryotic cells, posttranslational modifications (PTMs) on histones regulate chromatin structure and thus impact nearly all chromatin-templated events, including replication, transcription, and DNA repair. During S phase, newly synthesized histones are deposited onto DNA, leading to dilution of total chromatin-associated
