This is a review article from
Nature Cell Biology that systematically explores
translational regulation in the context of cellular
stress biology and
aging. The authors focus on how three age-associated stressors—loss of proteostasis, oxidative damage, and dysregulated nutrient sensing—modify
protein synthesis. The text details the specific
molecular mechanisms by which cells sense these stresses and implement corresponding adaptive or, at times, deleterious translational programs, such as activating the
Integrated Stress Response (ISR) or inhibiting
mTORC1 signaling. Ultimately, the review compares the translational changes observed during acute stress responses with the patterns of
protein synthesis alterations that occur during healthy and unhealthy aging to better understand longevity.
