Abstract
Epigenetics is the study of how cells control gene activity without changing the DNA sequence. Various epigenetic processes have been identified, including methylation, acetylation, phosphorylation, and ubiquitylation. Epigenetic processes are natural and essential to cell functions; however, when they occur improperly or at the wrong time, adverse effects can occur. A significant epigenetic process is chromatin modification. Chromatin–DNA complexes can be modified by acetylation, altering chromatin structure to influence gene expression. Stresses to hematopoietic stem and progenitor cells, such as ionizing radiation and aging, have significant effects on genomic function. Understanding epigenetic regulation in hematopoietic cells, particularly under stress, offers the potential for therapeutic intervention. We have utilized Chromatin immunoprecipitation (ChIP) in HSPCs to understand epigenetic regulation in response to ionizing radiation. This technique can be applied reliably to rare hematopoietic cells and offers a powerful tool to explore epigenetic regulation in HSPCs.
