چکیده انگلیسی
Neutrophil gelatinase-associated lipocalin (Ngal) is a biomarker for acute and chronic renal injuries, including polycystic kidney disease (PKD). However, the effect of Ngal on PKD progression remains unexplored. To study this, we generated 3 strains of mice with different expression levels of Ngal within an established PKD model (Pkd1L3/L3): Pkd1L3/L3 (with endogenous Ngal), Pkd1L3/L3; NgalTg/Tg (with endogenous and overexpression of exogenous kidney-specific Ngal) and Pkd1L3/L3; Ngal-/- mice (with Ngal deficiency). Knockout of endogenous Ngal had no effect on phenotypes, cystic progression, or survival of the PKD mice. However, the transgenic mice had a significantly longer lifespan, smaller (but not fewer) renal cysts, and less interstitial fibrosis than the mice without or with endogenous Ngal. Western-blot analyses showed significant increases in Ngal and cleaved caspase-3 and decreases in α-smooth muscle actin, hypoxia-inducible factor 1-α, pro-caspase 3, proliferating cell nuclear antigen, Akt, mammalian target of rapamycin, and S6 Kinase in the transgenic mice as compared with the other 2 strains of PKD mice. Thus, overexpression of exogenous kidney-specific Ngal reduced cystic progression and prolonged the lifespan in PKD mice, was associated with reductions in interstitial fibrosis and proliferation, and augmented apoptosis.
