Klotho, named after the youngest of the three Fates in Greek mythology daughters of Zeus and Nyx, who together spin the thread of life, allot destiny, and determine the time of passing for both mortals and immortals, is an important regulatory factor in aging and cancer dynamics. Initially described as an aging-suppressing protein, Klotho is now recognized for its more diverse role in modulating key signaling pathways like Wnt/β-catenin, IGF-1, PI3K/AKT, and TGF-β. Essentially, its various pro-cellular health functions, such as antioxidant, anti-inflammatory, and tumor-suppressive activities, are, in fact, considered that ensures the maintenance of cellular health and reduce complications related to aging. Klotho deficiency is associated with accelerated aging, chronic kidney disease, cardiovascular disorders, neurodegeneration, and various cancers. This review thus covers the twin roles of Klotho as an antiaging and tumor-suppressor protein, on their therapeutic potential, as well as advances in delivery systems and development of biomarkers and challenges for clinical translation.. Moreover, natural strategies like exercise and dietary interventions are explored that could help overcome Klotho deficiency. Further research with Klotho may offer a paradigm shift in the treatment of aging and cancer and add yet another avenue to increase survival of the patients.
