Hdac Histone Deacetylase Inhibitor
Histone Deacetylase (HDAC) inhibitors are a class of compounds that function as epigenetic modulators. To understand their role, one must look at how DNA is packaged. DNA is wrapped around proteins called histones. When acetyl groups are attached to these histones, the DNA is "relaxed," allowing genes to be expressed. HDAC enzymes remove these groups, causing the DNA to wrap more tightly and "silencing" those genes. By inhibiting these enzymes, HDAC inhibitors keep the DNA in an open state, which can re-activate genes that suppress tumor growth or trigger programmed cell death (apoptosis).
