When cells experience oxidative stress, the integrated stress response (ISR) signaling pathway is activated. One of the first outcomes of such ISR-activated response is to temporarily halt protein synthesis, which aids in cellular recovery. However, if cells cannot recover from the stress, they activate the cell death pathways which kills the affected cells, usually by apoptosis, which can then lead to either acquisition or prevention of diseases depending on the situation. In physiological aging, a compromised stress response is observed as an organism ages, which leads to disrupted homeostasis and elevated risk of disease. Thus, longevity of an organism is …
