Recent evidence suggests that dysregulation of microRNAs are associated with the development of multiple malignancies.miR-186 has been reported as a critical cancer regulator in several types of cancers. However, its functional significance and molecular mechanism underlying renal cell carcinoma (RCC) remains unknown. In this study, our results showed that miR-186 expression was dramatically downregulated in RCC tissues and cell lines compared to that in adjacent normal tissues and cell lines. Overexpression of miR-186 significantly inhibited cell growth, colony formation, cell invasion, caused cell cycle arrest at G0/G1 phase, and induced cell apoptosis as detected by MTT, colony formation, Transwell assay, and flow cytometry assays in RCC cells...

OBJECTIVES: To compare renal functional changes after percutaneous cryoablation (CA) or partial nephrectomy (PN). PATIENTS AND METHODS: Patients who underwent CA or PN for a solitary renal mass at a single institution were identified (2003-2013). Estimated glomerular filtration rates (eGFR) were calculated at baseline, discharge, and 3 months follow-up using the Chronic Kidney Disease Epidemiology Collaboration equation. Changes in renal function were compared between groups using 1:1 propensity score (PS) matching, adjustment for PS quintile, and inverse probability weighting (IPW)...

BACKGROUND: Nearly 30% of clear cell renal cell carcinoma (ccRCC) patients present with metastasis at the time of diagnosis, and the prognosis for these patients is poor. Therefore, novel potential prognostic biomarkers and therapeutic targets for ccRCC could be helpful. Emerging evidence indicates that lncRNAs play important roles in cancer tumorigenesis and could be used as potential biomarkers or therapeutic targets. PANDAR (promoter of CDKN1A antisense DNA damage activated RNA) is a relatively novel lncRNA that plays an important role in the development of multiple cancers...

Long non-coding RNAs (lncRNAs) have emerged as new gene regulators and prognostic markers in various cancers. Although the lncRNA nuclear enriched abundant transcript 1 (NEAT1) has been associated with tumorigenesis, its functions in renal cell carcinoma (RCC) have not been elucidated. We determined that NEAT1 is up-regulated in RCC tissue compared to corresponding non-tumor tissue. High NEAT1 expression was associated with tumor progression and poor survival in RCC patients. NEAT1 knockdown suppressed RCC cell proliferation by inhibiting cell cycle progression, and inhibited RCC cell migration and invasion by reversing the epithelial-to- mesenchymal transition phenotype...

Sickle cell disease (SCD) and its variants are genetic disorders resulting from the presence of a mutated form of hemoglobin. Renal disease is one of the most frequent complications, and kidney damage starts very early and progresses throughout life causing severe complications. The present study is aimed to analyze creatinine-based estimated glomerular filtration rate (eGFR) in 616 SCD patients (507 HbSS and 109 HbSB+), receiving medical care at outpatient wing of Sickle Cell Institute, Chhattisgarh. Glomerular filtration rate (GFR) estimated using the Modification of Diet in Renal Disease (MDRD), Cockcroft-Gault, chronic kidney disease epidemiology collaboration (CKD-EPI) (<17 years analyzed with Schwartz), and SCD specific Jamaica Sickle Cell Cohort Study (JSCCS)-GFR equations were compared...

Determination of the protein composition of urine is a non-invasive method helping to diagnose renal lesions and evaluate therapeutic interventions. We present here five observations that highlight the performance and relevance of urine protein analysis combining selected glomerular and tubular protein measurements. Total urine protein level and measurements of urinary IgG, albumin, transferrin alpha-1 microglobulin and retinol binding protein were performed on a urine sample by immunonephelometry. The results were normalized for urine creatinine concentration and integrated in the MDI interpretation software that provides a "urine protein profile" (UPP)...

Renal disease caused by cholesterol crystal embolism (CCE) occurs when cholesterol crystals become lodged in small renal arteries after small pieces of atheromatous plaques break off from the aorta or renal arteries and shower the downstream vascular bed. CCE is a multisystemic disease but kidneys are particularly vulnerable to atheroembolic disease, which can cause an acute, subacute, or chronic decline in renal function. This life-threatening disease may be underdiagnosed and overlooked as a cause of chronic kidney disease (CKD) among patients with advanced atherosclerosis...

REVIEW

Chronic kidney disease (CKD) can be a life-threatening condition, which eventually requires renal replacement therapy through dialysis or transplantation. A lot of effort and resources have been invested the last years in the identification of novel markers of progression and targets for therapy, in order to achieve a more efficient prognosis, diagnosis, and treatment of renal diseases. Using experimental models of renal disease, we identified and studied two promising candidates: periostin, a matricellular protein with high expression in bone and dental tissues, and discoidin domain receptor 1 (DDR1), a transmembrane collagen receptor of the tyrosine kinase family...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is a genetic ciliopathy disease characterized by progressive formation and enlargement of cysts in multiple organs. The kidneys are particularly affected and patients may eventually develop end-stage renal disease (ESRD). We hypothesize that bone marrow mesenchymal stromal cells (BMMSCs) are renotropic and may improve kidney function via anti-apoptotic, anti-fibrotic, and anti-inflammatory effects. In this study, we aim to assess the safety and tolerability of a BMMSC infusion in ADPKD patients...

BACKGROUND: BK polyomavirus-associated nephropathy is an important cause of post-transplantation renal failure. We present two cases of BK polyomavirus-associated nephropathy who were submitted to contrasting strategies of clinical follow-up to BK polyomavirus reactivation, but progressed to a similar final outcome. CASE PRESENTATION: Case 1 is a 37-year-old white man whose graft had never presented a good glomerular filtration rate function, with episodes of tacrolimus nephrotoxicity, and no urinary monitoring for BK polyomavirus; stage B BK polyomavirus-associated nephropathy was diagnosed by biopsy at 14 months post-transplant...

A direct and independent association between serum phosphate (P) levels and mortality has been reported. High circulating P concentrations, still within the normal range, was associated with unfavourable outcomes in normal subjects as well as in chronic kidney disease (CKD) patients. Experimental data support the notion that P overload may hamper survival expectancy, directly inducing vascular, skeletal, and renal ageing. The balance of P results from dietary intake, intestinal absorption, glomerular filtration, tubular resorption, and hormonal asset...

Incomplete understanding remains in the molecular mechanisms underlying progression and metastasis of renal cancer. The transcription factor SOX4 is upregulated in various human malignancies, including renal cancer, indicating it may be involved in renal tumorigenesis. In this study, we explored this hypothesis by loss-of-function and gain-of-function assays of SOX4 in renal cancer cell lines and renal epithelial cell line. We found that specific knockdown of SOX4 in renal cancer cell lines significantly suppressed the migration and invasion of cancer cells; specific overexpression of SOX4 in renal epithelial cell line markedly promoted the migration and invasion of the cell line...

A large number of previous clinical studies have reported a delayed graft function for brain dead donors, when compared with living relatives or cadaveric organ transplantations. However, there is no accurate method for the quality evaluation of kidneys from brain‑dead donors. In the present study, two‑dimensional gel electrophoresis and MALDI‑TOF MS‑based comparative proteomic analysis were conducted to profile the differentially‑expressed proteins between brain death and the control group renal tissues...

INTRODUCTION: Patients with light chain myeloma frequently have a light chain tubular cast nephropathy, which can lead to severe renal impairment. In the present retrospective study, bortezomib was combined with other active substances like bendamustine and prednisone (BPV), in order to assess the efficacy and toxicity of the combination therapy in patients with light chain multiple myeloma. METHODS: Between September 2008 and May 2015, 25 patients with newly diagnosed light chain multiple myeloma were treated with bendamustine 60 mg/m(2) on days 1 and 2, bortezomib 1...

Ascites is the most common complication related to cirrhosis and is associated with increased morbidity and mortality. Ascites is a consequence of the loss of compensatory mechanisms to maintain the overall effective arterial blood volume due to worsening splanchnic arterial vasodilation as a result of clinically significant portal hypertension. In order to maintain effective arterial blood volume, vasoconstrictor and antinatriuretic pathways are activated, which increase overall sodium and fluid retention...

Magnetic resonance imaging (MRI) examinations provide high-resolution information about the anatomic structure of the kidneys and are used to measure total kidney volume (TKV) in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD). Height-adjusted TKV (HtTKV) has become the gold-standard imaging biomarker for ADPKD progression at early stages of the disease when estimated glomerular filtration rate (eGFR) is still normal. However, HtTKV does not take advantage of the wealth of information provided by MRI...

The most frequent ureteral lesions are iatrogenic, mainly due to gynecologic and urologic procedures. The resolution and repair of these lesions, when they require surgery, is often the performance of ureteroneocystostomy. We describe the technique for the repair of distal ureter lesions that preserves both anatomy and function of the urinary tract (1). The operation consists in dissection and extraction of the distal ureteral stump from its intramural tract to get at least 1 cm of free ureter, percutaneous insertion of a ureteral stent, checking the absence of tension between proximal ureter and distal dissected stump, end to end anastomosis and reinsertion of the distal ureter in the previously dissected bladder muscle layer...

Background. Despite enzyme replacement therapy, Fabry nephropathy still progresses. Podocyturia is an irreversible event that antedates proteinuria and leads to chronic renal failure. We evaluated a potential mechanism of podocyte detachment via the expression of the urokinase-type Plasminogen Activator Receptor (uPAR) in urinary podocytes of Fabry patients. Methods. This is a cross-sectional study that included controls (n = 20) and Fabry patients (n = 44) either untreated (n = 23) or treated with agalsidase-β (n = 21)...

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by innumerous fluid-filled cysts and progressive deterioration of renal function. Previously, we showed that periostin, a matricellular protein involved in tissue repair, is markedly overexpressed by cyst epithelial cells. Periostin promotes cell proliferation, cyst growth, interstitial fibrosis, and the decline in renal function in PKD mice. Here, we investigated the regulation of these processes by the integrin-linked kinase (ILK), a scaffold protein that links the extracellular matrix to the actin cytoskeleton and is stimulated by periostin...
