Outline of Final Research Achievements |
Smoking is considered an environmental aging accelerator. While aging is unavoidable, the aging mechanism is still unclear because of its complexity. We focused on the anti-aging protein alpha-Klotho and the beta-Klotho-associated protein fibroblast growth factor (FGF)-21 to evaluate the acceleration of aging induced by smoking habit. From the study, we found that smoking simultaneously increases two Klotho-related molecules; alpha-Kltho and FGF-21, in male subjects. We speculate that acceleration of aging induced by smoking can be explained from two aspects, inflammation and metabolic disorders, respectively associated with alpha-Klotho and FGF-21. Moreover, we examined sex differences of these Klotho-related molecules. We found that Klotho-related molecules showed a differential association and response to smoking between men and women.
