SCOPE: Diabetic nephropathy (DN) is a micro-vascular complication of chronic diabetes. Sterol regulatory element binding protein1 (SREBP1) participation in the development of DN is reported. Oryzanol Concentrate (OC) at 0.1 and 0.3% was tested for its antioxidant and hypolipidemic effects. The aim of the work was to study the involvement of OC in the amelioration of DN in STZ induced diabetic animal model. METHODS AND RESULTS: Animals were grouped into Starch, High fat and OC treated control/diabetic groups (SFC/SFD, HFC/HFD, OFC/OFD)...

Chronic kidney disease (CKD) represents the fastest growing pathology worldwide with a prevalence of >10% in many countries. In addition, kidney cancer represents 5% of all new diagnosed cancers. As currently no effective therapies exist to restore kidney function after CKD- as well as cancer-induced renal damage, it is important to elucidate new regulators of kidney development and disease as new therapeutic targets. G protein-coupled receptors (GPCRs) represent the most successful class of pharmaceutical targets...

Diabetic nephropathy is associated with increased risk of cardiovascular disease. B-type natriuretic peptide (BNP) plays an important role in cardiovascular pathophysiology and therapeutics. The aim of the present study was to investigate the influence of experimental diabetes on the mechanisms that regulate the relaxant response of the rabbit renal artery to BNP. Arterial relaxations to BNP were enhanced in diabetic rabbits. Indomethacin enhanced BNP-induced relaxation in control rabbits but showed no effect in diabetic rabbits...

Type 2 diabetes has an increasing prevalence. Life expectancy is dominated by cardiovascular risk, which is the leading cause of death in these patients. Up to one third of diabetic patients will develop diabetic nephropathy related to micro-angiopathy. Renal impairment further increases cardiovascular risk. Reducing cardiovascular morbidity and mortality is a major public health issue, as well as early preventing and managing chronic kidney disease (CKD). Good glycemic control prevents the micro-vascular complications of the disease (retinopathy, nephropathy, etc...

REVIEW
Megan Stevens, Sebastian Oltean
Vascular endothelial growth factor A (VEGF-A) is a prominent pro-angiogenic and pro-permeability factor in the kidney. Alternative splicing of the terminal exon of VEGF-A through the use of an alternative 3' splice site gives rise to a functionally different family of isoforms, termed VEGF-Axxx b, known to have anti-angiogenic and anti-permeability properties. Dysregulation of the VEGF-Axxx /VEGF-Axxx b isoform balance has recently been reported in several kidney pathologies, including diabetic nephropathy (DN) and Denys-Drash syndrome...

There remains a lack of robust mouse models with key features of advanced human diabetic nephropathy (DN). Few options of murine models of DN require mutations to be superimposed to obtain desired phenotypic characteristics. Most genetically modified mice are on the C57BL/6 background; however, they are notorious for resistance to develop DN. To overcome these conundrums, this study reports a novel DN model by challenging with advanced oxidation protein products (AOPPs) in streptozotocin-induced diabetic C57BL/6 mice...

BACKGROUND: Adiponectin is known to take part in the regulation of energy metabolism. AdipoRon, an orally-active synthetic adiponectin agonist, binds to both adiponectin receptors (AdipoR)1/R2 and ameliorates diabetic complications. Among the lipid metabolites, the ceramide subspecies of sphingolipids have been linked to features of lipotoxicity, including inflammation, cell death, and insulin resistance. We investigated the role of AdipoRon in the prevention and development of type 2 diabetic nephropathy...

BACKGROUND: Recent studies have shown that low hemoglobin (Hb) level promote the progression of chronic kidney disease. This study assessed the relationship between Hb level and type 1 diabetic nephropathy (DN) in Anhui Han's patients. METHODS: There were a total of 236 patients diagnosed with type 1 diabetes mellitus and (T1DM) seen between January 2014 and December 2016 in our centre. Hemoglobin levels in patients with DN were compared with those without DN. The relationship between Hb level and the urinary albumin-creatinine ratio (ACR) was examined by Spearman's correlational analysis and multiple stepwise regression analysis...

As the life expectancy is increasing, there is a rise in elderly population and consequent increase in the patients with renal disease. There is an inconsistency between clinical and histopathological diagnosis in elderly, and so renal biopsy is important in these patients to decide appropriate clinical management and prognosis. This study outlines the importance of renal biopsy in elderly and describes the clinical and pathologic spectrum of renal diseases in patient ≥60 years. All patients (age ≥60 years) undergoing renal biopsies from January 2011 to December 2014 were included in this retrospective study...

In tumor nephrectomy specimens, the evaluation of the normal renal parenchyma is often overlooked. A patient with both end-stage renal diseases (ESRDs) with a renal cell carcinoma is more likely to die of the ESRD rather than cancer. At the time of nephrectomy, a pathologist has a large amount of tissue available to him to comment upon the presence of disease in the nonneoplastic kidney. Hence, this study was undertaken with the idea of characterizing disease in the nonneoplastic kidney at the time of tumor nephrectomy...

Diabetic nephropathy (DN) is one of the common microvascular complications of diabetes mellitus. Renal fibrosis is closely related to the deterioration of renal function. The present study aimed to investigate protective effect of Taxus chinensis on high-fat diet/streptozotocin-induced DN in rats and explore the underlying mechanism of action. The rat DN model was established via feeding high fat diet for 4 weeks and subsequently injecting streptozotocin (30 mg·kg-1 body weight) intraperitoneally. The rats with blood glucose levels higher than 16...

Apoptosis and autophagy are harmoniously regulated biological processes for maintaining tissue homeostasis. AMP-activated protein kinase (AMPK) functions as a metabolic sensor to coordinate cellular survival and function in various organs, including the kidney. We investigated the renoprotective effects of cinacalcet in high-glucose treated human glomerular endothelial cells (HGECs), murine podocytes and C57BLKS/J-db/db mice. In cultured HGECs and podocytes, cinacalcet decreased oxidative stress and apoptosis and increased autophagy that were attributed to the increment of intracellular Ca2+ concentration and the phosphorylation of Ca2+ /calmodulin-dependent protein kinase kinaseβ (CaMKKβ)-Liver kinase B1 (LKB1)-AMPK and their downstream signals including the phosphorylation of endothelial nitric oxide synthase (eNOS) and increases in superoxide dismutases and B cell leukemia/lymphoma 2/BCL-2-associated X protein expression...

Signalling via the receptor of advanced glycation end-products (RAGE) although complex and not fully elucidated in the setting of diabetes, is considered a key injurious pathway in the development of diabetic nephropathy (DN). We report here that RAGE deletion resulted in increased expression of fibrotic (collagen I and IV, fibronectin) and the inflammatory marker, MCP-1 in primary mouse mesangial cells (MC) and in kidney cortex. RNA-seq analysis in MCs from RAGE -/- and wild type mice confirmed these observations...

The fractalkine receptor chemokine (C-X3-C motif) receptor 1 (CX3CR1) and its highly selective ligand CX3CL1 mediate chemotaxis and adhesion of immune cells, which are involved in the pathogenesis and progression of numerous inflammatory disorders and malignancies. The CX3CL1/CX3CR1 axis has recently drawn attention as a potential therapeutic target because it is involved in the ontogeny, homeostatic migration, or colonization of renal phagocytes. We performed a Medline/PubMed search to detect recently published studies that explored the relationship between the CX3CL1/CX3CR1 axis and renal diseases and disorders, including diabetic nephropathy, renal allograft rejection, infectious renal diseases, IgA nephropathy, fibrotic kidney disease, lupus nephritis and glomerulonephritis, acute kidney injury and renal carcinoma...

Diabetic nephropathy (DN) is one of the most severe microangiopathies of diabetes mellitus and is a leading cause of end stage renal disease. Numerous studies suggest that podocyte injury contributes to progressive proteinuria. Podocytes are highly specialized, terminally differentiated cells that are unable to proliferate, autophagy plays a key role in maintaining the structure and function of podocytes. Autophagy impairment is involved in the pathogenesis of podocyte loss, which leads to massive proteinuria in DN...
