dc.description.abstract | Proinflammatory cytokines contribute to renal injury, but the downstream effectors within kidney cells
are not well understood. One candidate effector is Klotho, a protein expressed by renal cells that has
antiaging properties; Klotho-deficient mice have an accelerated aging-like phenotype, including vascular
injury and renal injury. Whether proinflammatory cytokines, such as TNF and TNF-like weak inducer of
apoptosis (TWEAK), modulate Klotho is unknown. In mice, exogenous administration of TWEAK decreased
expression of Klotho in the kidney. In the setting of acute kidney injury induced by folic acid, the
blockade or absence of TWEAK abrogated the injury-related decrease in renal and plasma Klotho levels.
TWEAK, TNF , and siRNA-mediated knockdown of I B all activated NF B and reduced Klotho
expression in the MCT tubular cell line. Furthermore, inhibition of NF B with parthenolide prevented
TWEAK- or TNF -induced downregulation of Klotho. Inhibition of histone deacetylase reversed TWEAKinduced
downregulation of Klotho, and chromatin immunoprecipitation showed that TWEAK promotes
RelA binding to the Klotho promoter, inducing its deacetylation. In conclusion, inflammatory cytokines,
such as TWEAK and TNF , downregulate Klotho expression through an NF B-dependent mechanism.
These results may partially explain the relationship between inflammation and diseases characterized by
accelerated aging of organs, including CKD. | en_US |
