The discovery of histone acetylation causing changes in transcription activity can be traced back to the work of Vicent Allfrey and colleagues in 1964. The group hypothesized that histone proteins modified by acetyl groups added negative charges to the positive lysines, and thus, reduced the interaction between DNA and histones. Histone modification is now considered a major regulatory mechanism that is involved in many different stages of genetic functions. Our current understan… Web19 ian. 2024 · Lysine L-lactylation [K (L-la)] is a newly discovered histone mark stimulated under conditions of high glycolysis, such as the Warburg effect.
