Stress response pathways are cellular mechanisms for resisting the effects of environmental stressors and internal disturbances to maintain cellular integrity, function, survival, and adaptability. Without these pathways, cells become damaged, stop functioning, and eventually die, which can disrupt the proper functioning of processes required for an organism's survival and initiate pathogenesis. Hence these pathways prevent the onset and progression of diseases, including cancer, neurodegenerative disorders, and cardiovascular diseases.
