Mimetics of hormetic agents offer a novel approach to adjust dose to minimize the risk of toxic response, and maximize the benefit of induction of at least partial physiological conditioning. Nature selected and preserved those organisms and triggers that promote tolerance to stress. The induced tolerance can serve to resist that challenge and can repair previous age, disease, and trauma damage as well to provide a more youthful response to other stresses. The associated physiological conditioning may include youthful restoration of DNA repair, resistance to oxidizing pollutants, protein structure and function repair, improved immunity, tissue remodeling, adjustments in central and peripheral nervous systems, and altered metabolism. By elucidating common pathways activated by hormetic agent's mimetics, new strategies for intervention in aging, disease, and trauma emerge. Intervention potential in cancer, diabetes, age-related diseases, infectious diseases, cardiovascular diseases, and Alzheimer's disease are possible. Some hormetic mimetics exist in pathways in primitive organisms and are active or latent in humans. Peptides, oligonucleotides, and hormones are among the mimetics that activate latent resistance to radiation, physical endurance, strength, and immunity to physiological condition tolerance to stress. Co-activators may be required for expression of the desired physiological conditioning health and rejuvenation benefits.
激动剂模拟物为调整剂量以最小化毒性反应风险并最大化诱导至少部分生理适应的益处提供了一种新方法。自然选择并保留了那些促进对压力耐受的生物体和触发因素。诱导的耐受可以抵抗该挑战,并可以修复以前的年龄、疾病和创伤损伤,以及对其他压力产生更年轻的反应。相关的生理适应可能包括 DNA 修复、抵抗氧化污染物、蛋白质结构和功能修复、改善免疫、组织重塑、中枢和外周神经系统的调整以及代谢的改变。通过阐明激动剂模拟物激活的共同途径,出现了干预衰老、疾病和创伤的新策略。在癌症、糖尿病、与年龄相关的疾病、传染病、心血管疾病和阿尔茨海默病方面具有干预潜力。一些激动剂模拟物存在于原始生物体的途径中,并且在人类中是活跃或潜伏的。肽、寡核苷酸和激素是激活潜在的辐射抗性、身体耐力、力量和对生理适应压力耐受的免疫的模拟物之一。共激活剂可能是表达所需的生理适应健康和恢复活力益处所必需的。
