Metabolic stressors disrupt proteome homeostasis to suppress malignancy
Within tumor cells the heat shock factor 1 (HSF1)-mediated stress response is constitutively mobilized to counter persistent proteotoxic stress, thus sustaining their fragile proteome homeostasis and supporting robust malignant phenotypes. Intriguingly, our new studies reveal that metabolic stressor...

| Sumario: | Within tumor cells the heat shock factor 1 (HSF1)-mediated stress response is constitutively mobilized to counter persistent proteotoxic stress, thus sustaining their fragile proteome homeostasis and supporting robust malignant phenotypes. Intriguingly, our new studies reveal that metabolic stressors, such as metformin, inactivate HSF1 and provoke proteomic chaos, thereby impeding tumorigenesis. |
