Lipid Deposition in Kidney Diseases: Interplay Among Redox, Lipid Mediators, and Renal Impairment.
Significance:The relationship between lipid disturbances and renal diseases has been studied for several decades, and it is well recognized that when the balance of renal lipid uptake, synthesis, oxidation, and outflow is disrupted, lipids will undergo oxidation, be sequestrated as lipid droplets, generate toxic metabolites, and cause nephrotoxicity in diverse renal diseases.Recent Advances:During renal disorders, redox signaling is a pivotal event promoting or resulting from lipid disorders. Accordingly, a vicious cycle of lipid redox dysregulation could be developed, accelerating the renal damage.Critical Issues:The aim of this concise review is to introduce the connection among redox, lipid abnormalities and kidney damage in various conditions. And we summarized current understanding of the lipid redox loop implicated in acute kidney injury, chronic kidney disease, metabolic abnormalities, aging, and genetic pitfalls.Future Directions:Despite recent advances, further investigations are required to clarify the complicated molecular and regulatory mechanisms among redox, lipid mediators and renal disorders. Moreover, exploring an ideal target for potential therapies should be discussed and studied in future.Antioxid. Redox Signal.28, 1027-1043.
