Inhibition of Necroptosis Attenuates Kidney Inflammation and Interstitial Fibrosis Induced By Unilateral Ureteral Obstruction.

CONCLUSION: These findings suggest that the participation of necroptosis in UUO is partly demonstrated. And necroptosis inhibition may have a potential role in the treatment of diseases with increased inflammatory response and interstitial fibrosis in renal.

ConclusionsDependent on dose, RSV activated either anti-fibrotic or pro-fibrotic effects in kidneys. The risk of RSV consumption in individuals with impaired kidney function should be carefully considered.Graphical Abstract

AbstractProgressive renal fibrosis is the last phase of chronic kidney disease and results in renal failure. Micro-RNA has been demonstrated as important agent to drive organ fibrosis. However, the precise mechanisms are not fully understood. Here, we found miRNA-184 as a critical mediator to promote the renal fibrosis by targeting HIF1AN. In Vivo, miRNA-184 expression levels remarkably increased both in patients ’ serum and in unilateral ureteral obstruction kidneys, as well as induced the expression of COL1A1 and COL3A1. Furthermore, transfection of NRK49F cells with miRNA-184 mimics down-regulated HIF1AN, transfec...

Congenital obstructive nephropathy is a major cause of chronic kidney disease in children. The contribution of changes in the identity of renal cells to the pathology of obstructive nephropathy is poorly understood. Using a partial unilateral ureteral obstruction model in genetically modified neonatal mice, we traced the fate of cells derived from the renal stroma, cap mesenchyme, ureteric bud epithelium and podocytes using Foxd1Cre , Six2Cre , HoxB7Cre and Podocyte.Cre mice respectively, crossed with double fluorescent reporter (mT/mG) mice. Persistent obstruction leads to a significant loss of tubular epithelium, rarefac...

Conclusions Nephrostomy tube placement was associated with pyelonephritis and AB in 44% of cases overall. Pseudomonas and Enterococcus species were the most common pathogens. Isolation of resistant organisms was mostly observed in the pyelonephritis group.

Abstract Chronic kidney disease (CKD) has become a major public health problem worldwide and has a great impact on the quality of life of millions of people. Long-term obstructive uropathy is an important cause of CKD. We hypothesized diagnostic biomarkers for early stage obstructive nephropathy can be discovered by metabolomic profiling of biofluid. Unilateral ureteral occlusion (UUO) surgery was performed on rats to induce renal interstitial fibrosis. Sham-operated rats were used as controls. Plasma and urine metabolites were analyzed by UPLC-MS based metabolomic approach. Significant metabolic profiling separat...

Transforming growth factor–β (TGF-β) is a well-established central mediator of renal fibrosis, a common outcome of almost all progressive chronic kidney diseases. Here, we identified a poorly conserved and kidney-enriched long noncoding RNA in TGF-β1–stimulated human tubular epithelial cells and fibrotic kidneys, which we termed TGF-β/Smad3-interacting long noncoding RNA (lnc-TSI). Lnc-TSI was transcriptionally regulated by Smad3 and specifically inhibited TGF-β–induced Smad3 phosphorylation and downstream profibrotic gene expression. Lnc-TSI acted by binding with the MH2 domain o...

CONCLUSIONS: The antifibrotic effects of tamoxifen are associated with the suppression of Src kinase function via ER-α, followed by inhibition of the PI3K/Akt and mTOR/p70S6K signaling pathways. SIGNIFICANCE: Our findings suggest that tamoxifen is a novel therapeutic option for the prevention and treatment of renal fibrosis. This article is protected by copyright. All rights reserved.

Abstract Renal fibrosis is a common pathological feature in chronic kidney disease (CKD), including diabetic kidney disease (DKD) and obstructive nephropathy. Multiple microRNAs have been implicated in the pathogenesis of both DKD and obstructive nephropathy although the overall role of microRNAs in tubular injury and renal fibrosis in CKD is unclear. Dicer (a key RNase III enzyme for microRNA biogenesis) was specifically ablated from kidney proximal tubules in mice via the Cre/lox system to deplete micoRNAs. Proximal tubular Dicer knockout (PT- Dicer KO) mice and wild-type (WT) littermates were subjected to strep...

Conclusion: MK stent is a safe and efficient minimally invasive long-term treatment option to preserve GFR in patients who develop CKD through ureteroileal anastomotic stricture. In spite of MK stent insertion and alleviation of obstruction, it was presumably inserted too late to improve renal function.Urol Int

In this study, we first demonstrated that PA ameliorates fibroblast activation and renal interstitial fibrosis. Our results indicate that PA may be useful as a potential candidate in the prevention of chronic kidney disease.
