α-Decitabine is a chemical of interest in the field of molecular genetics for studying epigenetic modifications and gene expression regulation. As an analogue of cytidine, it is embedded to investigate the mechanisms of DNA methylation, a key process that affects gene activity without altering the DNA sequence itself. In some studies, α-Decitabine is utilized to explore the effects of DNA methylation inhibitors on gene expression, providing insights into how epigenetic changes can influence cellular differentiation and function. α-Decitabine is also useful for studying of epigenetic markers for various biological processes and the potential reversibility of epigenetic states.
