    Targeting DNA topoisomerases or checkpoint kinases results in an overload of chaperone systems, triggering aggregation of a metastable subproteome

    Wouter Huiting, Suzanne L Dekker ... Steven Bergink
    Various genotoxic stresses trigger widespread aggregation of abundant, liquid-liquid phase separation-prone proteins, suggesting that genotoxic stress is a potential driver of disease-associated protein aggregation.
