Used in epigenetic research to modulate gene expression by inhibiting histone acetylation. This compound helps study the role of acetyltransferases in cellular processes such as transcription, cell cycle regulation, and differentiation. It is also employed in cancer research due to its potential to reactivate tumor suppressor genes silenced by aberrant acetylation patterns. Commonly applied in in vitro assays to investigate signaling pathways and evaluate therapeutic targets in diseases linked to epigenetic dysregulation.
