Could Notch signaling pathway be a potential therapeutic option in renal diseases?

Notch pathway regulates key processes in the kidney, involved in embryonic development and tissue damage. In many human chronic renal diseases a local activation of Notch pathway has been described, suggesting that several components of Notch pathway could be considered as biomarkers of renal damage. Experimental studies by genetic modulation of Notch components or pharmacological approaches by gamma-secretase inhibitors have demonstrated the role of this pathway in renal regeneration renal, podocyte apoptosis, proliferation and fibroblasts activation, and induction of epithelial to mesenchymal transition of tubular epithelial cells. Recent studies suggest an interaction between Notch and NF-kappa B pathway involved in the regulation of renal inflammatory process. On the other hand, there are some miRNAs that could regulate Notch components and down-stream responses. All these data suggest that Notch blockade could be a novel therapeutic option for renal diseases. (c) 2018 Sociedad Espanola de Nefrologia. Published by Elsevier Espana, S.L.U.
