Fig. 2From: Exploring the role of histone deacetylase and histone deacetylase inhibitors in the context of multiple myeloma: mechanisms, therapeutic implications, and future perspectivesAcetylation of lysine in histone and non-histone proteins. Histone acetylation causes a loose chromatin structure, which causes gene expression. Additionally, the double-edged sword role of autophagy in tumor development and progression.
