WebSep 16, 2024 · Nucleolus, as the largest nuclear body, is regarded as a central hub in coordinating cellular stress response by regulating ribosome subunit biogenesis and cell cycle progression. In response to stress, nucleolus can control the activity of the tumor suppressor protein p53 or crosstalk with Cajal bodies (Boulon et al., 2010 ). WebThe nucleolus is the largest and most studied nuclear body, but its role in nuclear function is far from being comprehensively understood.
