Feast or famine: Scientists find key bio ’switch‘ that helps cells adapt

Scientists have found that a chemical mark on histones – a key protein involved in the function of our DNA – occurs naturally under nutrient-limited conditions as cells change the way they make energy, and serves to repress genes that would otherwise drive cell growth. The chemical mark is called crotonylation, and until now its function has not been well understood.
