The aim of the study is to clarify the role of hypoxia-inducible factor-1 (HIF-1) in the development of renal fibrosis in mouse obstructive nephropathy. We used mice with floxed HIF-1α alleles and tamoxifen-inducible Cre/ERT2 recombinase under ubiquitin C promoter to induce global HIF-1α deletion. Following tamoxifen administration, mice were subjected to unilateral ureteral obstruction (UUO). At 3, 7 and 14 days after UUO, renal gene expression profiles and interstitial fibrosis were assessed. HIF-1 dependent up-regulation of prolyl hydroxylase 3 and glucose transporter-1 was observed in the obstructed kidney at 3 and 7 days but not at 14 days after UUO...

Although yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ), nuclear transducers of the Hippo pathway, are mostly silent in adult organs, aberrant activation of YAP/TAZ promotes tumorigenesis and abnormal tissue repair. The extent of involvement of TAZ in chronic kidney disease (CKD) is unknown. In our study, increased TAZ nuclear accumulation and expression in the tubulointerstitium was readily evident in 3 models of renal injury including obstructive, aristolochic acid (AA), and diabetic nephropathy, correlating with fibrosis progression...

Acute kidney injury (AKI) in cancer patients may disrupt anticarcinogenic treatment and greatly increase associated mortality rates. The present study reported on the management of cancer patients with AKI and, from the nephrologic viewpoint, on the significance of fine volume control during the continuous renal replacement therapy (CRRT). The records of 117 cancer patients with AKI treated over three years were reviewed and their data were compared with those of 120 healthy controls. AKI was defined according to the Kidney Disease: Improving Global Outcomes criteria with serum creatinine levels determined on initial admission and for the diagnosis of AKI...

The epithelial-to-mesenchymal transition (EMT) induced by chronic hypoxia is one of the critical causes of renal fibrosis. Previous work reported that the transcription factors Twist plays an important role in hypoxia-induced EMT and renal fibrosis. Recent evidence indicates that miR-214 was regulated by Twist in many fibrotic diseases, but their role in hypoxia-induced EMT and renal fibrosis remains unknown. Here, we found that hypoxia significantly upregulated the expression of miR-214-3p in HK-2 cells, unilateral ureteral obstruction (UUO) nephropathy and patients with chronic kidney disease...

Novel therapies are urgently needed to address the rising incidence and prevalence of acute kidney injury (AKI) and chronic kidney disease (CKD). Mesenchymal stem/stromal cells (MSCs) have shown promising results in experimental AKI and CKD, and have been used in the clinic for more than a decade with an excellent safety profile. The regenerative effects of MSCs do not rely on their differentiation and ability to replace damaged tissues, but are primarily mediated by the paracrine release of factors, including extracellular vesicles (EVs), composed of microvesicles and exosomes...

Congenital obstructive nephropathy is amongst the main causes of chronic renal failure in children. Early diagnosis and initiation of the treatment will delay progressive renal tubular atrophy and interstitial fibrosis with the loss of nephrons. The aim of this study was to evaluate whether urinary (u) semaphorin-3A (SEMA-3A) and Netrin-1 may be potential biomarkers in children with congenital hydronephrosis due to ureteropelvic junction obstruction (UPJO). The study consisted of 42 children with severe hydronephrosis who needed surgery and two control groups (Control One: 42 children with mild, non-obstructive hydronephrosis; Control Two: 44 healthy children)...

β-Catenin signalling plays an important role in regulating tubular epithelial-to-mesenchymal transition (EMT), an indispensable programme for driving renal fibrosis. As an adapter protein, four and a half LIM domain protein 2 (FHL2) acts as a coregulator of β-catenin in several other cell types. To determine whether FHL2 affects β-catenin signalling and thus is involved in tubular EMT, we examined its expression and function in the process of TGF-β1-induced EMT. FHL2 mRNA and protein were induced by TGF-β1 in rat tubular epithelial cells (NRK-52E), an effect that intracellular Smad signalling was required...

Despite substantial progress being made in understanding the mechanisms contributing to the pathogenesis of renal fibrosis, there are only a few therapies available to treat or prevent renal fibrosis in clinical use today. Therefore, identifying the key cellular and molecular mediators involved in the pathogenesis of renal fibrosis will provide new therapeutic strategy for treating patients with chronic kidney disease (CKD). β-Arrestin-1, a member of β-arrestin family, not only is a negative adaptor of G protein-coupled receptors (GPCRs), but also acts as a scaffold protein and regulates a diverse array of cellular functions independent of GPCR activation...

Transforming growth factor β (TGF-β)/Smad3 signaling plays a role in tissue fibrosis. We report here that Erbb4-IR is a novel long non-coding RNA (lncRNA) responsible for TGF-β/Smad3-mediated renal fibrosis and is a specific therapeutic target for chronic kidney disease. Erbb4-IR was induced by TGF-β1 via a Smad3-dependent mechanism and was highly upregulated in the fibrotic kidney of mouse unilateral ureteral obstructive nephropathy (UUO). Silencing Erbb4-IR blocked TGF-β1-induced collagen I and alpha-smooth muscle actin (α-SMA) expressions in vitro and effectively attenuated renal fibrosis in the UUO kidney by blocking TGF-β/Smad3 signaling...

Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized clinical entity that often involves multiple organs; it is characterized by high levels of serum immunoglobulin G4 (IgG4), dense infiltration of IgG4+ cells, and storiform fibrosis. Cellular immunity, particularly T cell-mediated immunity, has been implicated in the pathogenesis of IgG4-RD. The most frequent renal manifestations of IgG4-RD are IgG4-related tubulointerstitial nephritis, membranous glomerulonephropathy (MGN), and obstructive nephropathy secondary to urinary tract obstruction due to IgG4-related retroperitoneal fibrosis, prostatitis, or ureter inflammation...

An 83-year-old Japanese man had a history of chronic heart failure due to bradycardia-tachycardia syndrome. He was admitted to our hospital because of macrohematuria and acute kidney injury (AKI), which were detected by an urologist at an outpatient visit. He had a history of recurrent macrohematuria and transurethral resection of bladder tumors twice in the preceding 2 years. He had been on warfarin for 12 years, with a stable international normalized ratio (INR) that was usually less than 2.1. Urinalysis revealed numerous red blood cells (RBCs) and mild proteinuria without RBC casts...

Ectopic thoracic kidney is an extremely rare condition caused by the abnormal location of one or both kidneys in the thoracic cavity. They are usually discovered incidentally on routine imaging. Although commonly asymptomatic, thoracic kidneys are at a risk of malrotation, pelviureteric junction obstruction, and subsequent obstructive nephropathy, by virtue of their long pedicle. We present a case report of an incidental thoracic kidney, for which a 99mtechnetium-mercaptoacetyltriglycine (99mTc-MAG3) renogram was performed to assess the baseline renal function...

The contamination of ground water by fluoride has been reported worldwide. Most fluoride (approximately 70%) is filtered by the kidneys; humans or experimental animals with renal damage therefore may be more affected by fluoride exposure than those with normal kidney function. Tubulointerstitial fibrosis, which involves macrophage-promoted extracellular matrix production and myofibroblast migration, can be induced in rats by unilateral ureteral obstruction (UUO). We examined the effects of fluoride exposure on tubulointerstitial fibrosis in the obstructed kidney of UUO rats...

Vesicoureteral reflux (VUR) is the most common type of obstructive uropathy in children. Reflux nephropathy (RN) is one of the most common complications of VUR that inevitably leads to chronic kidney disease. Patients with end-stage kidney disease require costly treatment, and the only way to cure them is kidney transplantation. A timely institution of renoprotective therapy is a key factor helping to preserve the function of the native kidneys. Hence, it is necessary to devise new highly sensitive and minimally invasive methods for early diagnosis of RN...

Endovascular treatments have become increasingly common for patients with a variety of thoracic aortic pathologies. Although considered less invasive than traditional open surgical approaches, they are nonetheless complex procedures. Patients undergo manipulation of an often calcified aorta near the origin of the carotid and subclavian vessels and have stents placed in a curved vessel adjacent to a perpetually beating heart. These stents can obstruct blood flow to the spinal cord, induce an inflammatory response, and in rare cases erode into the adjacent trachea or esophagus...
