GSK-LSD1 Dihydrochloride is primarily used in research settings to study the role of lysine-specific demethylase 1 (LSD1) in various biological processes. It is a potent inhibitor of LSD1, an enzyme involved in the regulation of gene expression through histone modification. Researchers utilize this compound to investigate its effects on cancer progression, as LSD1 is often overexpressed in certain types of tumors. By inhibiting LSD1, it may help in understanding its role in cell differentiation, proliferation, and apoptosis, which are critical in cancer biology. Additionally, it is explored in epigenetic studies to uncover potential therapeutic strategies for diseases where abnormal gene expression plays a key role. Its application extends to neuroscience research, where LSD1 inhibition is studied in the context of neurodevelopmental and neurodegenerative disorders. Overall, GSK-LSD1 Dihydrochloride serves as a valuable tool in advancing knowledge in epigenetics and drug development.
