Abstract
Aging and pregnancy are often considered opposites in a woman’s biological timeline. Aging is defined by a gradual decline in the functional capabilities of an organism over its lifetime, while pregnancy is characterized by the presence of the transient placenta, which fosters the cellular fitness necessary to support fetal growth. However, in the context of preeclampsia, pregnancy and aging share common hallmarks, including clinical complications, altered cellular phenotypes, and heightened oxidative stress. Furthermore, women with pregnancies complicated by preeclampsia tend to experience age-related disorders earlier than those with healthy pregnancies. Klotho, a gene discovered fortuitously in 1997 by researchers studying aging mechanisms, is primarily expressed in the kidneys but also to a lesser extent in several other tissues, including the placenta. The Klotho protein is a membrane-bound protein that, upon cleavage by ADAM10/17, is released into the circulation as soluble Klotho (sKlotho) where it plays a role in modulating oxidative stress. This review focuses on the involvement of sKlotho in the development of preeclampsia and age-related disorders, as well as the expression of the recently discovered Mytho gene, which has been associated with skeletal muscle atrophyFile | Dimensione | Formato | |
