The aim of the present study was to examine the regulatory mechanism underlying the depression in Ski‑related novel protein N (SnoN) in diabetic nephrology (DN). NRK‑52E cells, a rat primary renal tubular epithelial cell line, were cultured to clarify the effect of small mothers against decapentaplegic (Smad) ubiquitination regulatory factor 2 (smurf2) on SnoN in a low glucose environment in vitro. NRK‑52E cells and DM rats were injected with adenoviruses AD‑smurf2 and AD‑shsmurf2, respectively, and the protein expression profiles of SnoN, smurf2 and phosphorylated (p)‑Smad2 were then detected...

Due to its pharmacological activities, Paecilomyces tenuipes has previously been used as a folk medicine in Asia. The primary aim of the present study was to investigate the hypoglycemic, hypolipidemic and anti‑nephritic effects of P. tenuipes N45 aqueous extracts (PTNE) in a high fat diet/streptozotocin‑induced diabetic rat model. The rats were treated with 120 mg/kg of metformin or 0.04, 0.2 or 1.0 g/kg PTNE for 4 weeks. The hypoglycemic activity of PTNE was confirmed by the observation of reduced fasting blood glucose level and by partially normalized oral glucose tolerance...

BACKGROUND: Diabetic nephropathy is a major complication of diabetes and an established risk factor for cardiovascular events. Lipid abnormalities occur in patients with diabetic nephropathy, which further increase their risk for cardiovascular events. We compared the degree of dyslipidemia among type 2 diabetes mellitus (T2DM) subjects with and without nephropathy and analyzed the factors associated with nephropathy among them. METHODS: In this retrospective study, T2DM patients with overt nephropathy were enrolled in the study group (n=89) and without nephropathy were enrolled in the control group (n=92)...

Diabetes is the leading cause of end stage renal disease, resulting in a significant health care burden and loss of economic productivity by affected individuals. As current therapies for progression of diabetic nephropathy (DN) are only moderately successful, identification of underlying mechanisms of disease is essential in order to develop more effective therapies. We showed previously that inhibition of arginase using S-(2-boronoethyl)-L-cysteine (BEC) or genetic deficiency of the arginase-2 isozyme was protective against key features of nephropathy in diabetic mouse models...

BACKGROUND: Altered regulation of extracellular matrix remodeling by matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinase (TIMP) may contribute to vascular complications in type 1 diabetes. We investigated associations between plasma MMP-1, -2, -3, -9, -10 and TIMP-1, and cardiovascular events and all-cause mortality in type 1 diabetic patients. METHODS: We prospectively followed 337 type 1 diabetic patients [mean age 41.4 years (9.6), 39% female], 170 with and 167 without diabetic nephropathy, with median follow-up of 12...

Diabetic nephropathy is the primary cause of end-stage renal disease. Apoptosis of tubule epithelial cells is a major feature of diabetic nephropathy. The mechanisms of high glucose (HG) induced apoptosis are not fully understood. Here we demonstrated that, HG induced apoptosis via upregulating the expression of proapoptotic Bcl-2 homology domain 3 (BH3)-only protein Bim protein, but not bring a significant change in the baseline level of autophagy in HK2 cells. The increase of Bim expression was caused by the ugregulation of transcription factors, FOXO1 and FOXO3a...

Carotenoids are a large class of natural antioxidants that occur in many vegetables, foods and other natural sources. To date, a large number of biological properties have been reported from carotenoids, particularly protective effects against diabetes mellitus (DM), cancer, and neurodegenerative, metabolic and cardiovascular diseases. However, recent studies including clinical evidences, have shown that carotenoids play a role in the treatment of diabetes via enhancing insulin sensitivity. They are also able to protect the body from long-term consequences of diabetes including infectious diseases, nephropathy, neuronal and eye abnormalities...

Metastasis associated lung adenocarcinoma transcript 1(MALAT1) is a long non-coding RNA, broadly expressed in mammalian tissues including kidney and up-regulated in a variety of cancer cells. To date, its functions in podocytes are largely unknown. β-catenin is a key mediator in the canonical and non-canonical Wnt signalling pathway; its aberrant expression promotes podocyte malfunction and albuminuria, and contributes to kidney fibrosis. In this study, we found that MALAT1 levels were increased in kidney cortices from C57BL/6 mice with streptozocin (STZ)-induced diabetic nephropathy, and dynamically regulated in cultured mouse podocytes stimulated with high glucose, which showed a trend from rise to decline...

Type 2 diabetes mellitus (T2DM) has growing prevalence worldwide and major clinical implications, chiefly cardiovascular (CV) and renal disease burden. Sodium-glucose co-transporter (SGLT)-2 inhibitors are a new drug class in the management of T2DM with a mechanism of action independent of insulin. In addition to their hypoglycaemic effect, SGLT-2 inhibitors appear to have haemodynamic and nephroprotective effects. Studies have consistently showed a modest but significant blood pressure (BP) reduction. Metabolic benefits are also attributed to SGLT-2 inhibitors with a modest but consistent body weight decrease recorded along with improvements in lipid profile and uric acid levels...

The worldwide prevalence of diabetes mellitus is expected to reach 439 million by 2030. Diabetes increases the risk for developing secondary complications such as nephropathy and cardiovascular disease, critical factors that dictate the survival rate of diabetes patients. Compelling evidence has indicated that the positive impact of fermentable carbohydrates in obesity-related diabetes is mediated by the production of short-chain fatty acids and the modulation of colonic microbiota. This review summarizes the potential implications of dietary resistant starch, a class of fermentable fiber, in glucose homeostasis and kidney health in obesity-associated diabetes and examines the mechanisms underlying the protective effect of resistant starch...

The underlying mechanisms in the development of diabetic nephropathy are currently unclear and likely consist of a series of dynamic events from the early to late stages of the disease. Diabetic nephropathy is currently without curative treatments and it is acknowledged that even the earliest clinical manifestation of nephropathy is preceded by an established morphological renal injury that is in turn preceded by functional and metabolic alterations. An early manifestation of the diabetic kidney is the development of kidney hypoxia that has been acknowledged as a common pathway to nephropathy...

INTRODUCTION    Diabetic foot (DF) is a devastating complication of diabetes mellitus (DM) that occurs due to neuropathy and/or atherosclerosis of the lower limbs. Omentin (encoded by the ITLN1 gene) has been implicated as a protective factor in vascular complications of diabetes, likely due to its endothelial vasodilator activity and its anti-inflammatory actions. However, susceptibility to DF in terms of ITLN1 gene polymorphisms has not been studied. OBJECTIVES    This study aimed to evaluate the association between ITLN1 gene polymorphism rs2274907and the occurrence of DF in patients with type 2 diabetes mellitus (T2DM)...

OBJECTIVE: Patients with obesity are at risk for chronic kidney disease. The aim is to characterize the spectrum of kidney disease in these patients, which may be related to obesity, termed obesity-related glomerulopathy (ORG), or may have other diseases secondary to associated or unassociated medical conditions. METHODS: Native kidney biopsies from 2000 to 2012 were retrospectively reviewed from all patients with body mass index >30kg/m(2). Glomerular diameter was measured using a standard micrometer and clinicopathologic characteristics were analyzed...

We have previously demonstrated that KMUP-1, a xanthine-based nitric oxide enhancer, attenuates diabetic glomerulosclerosis, while increasing renal endothelial nitric oxide synthase expression in rats. However, the anti‑fibrotic mechanisms of KMUP‑1 treatment in diabetic nephropathy in terms of cell biology and transforming growth factor-β1 (TGF‑β1) remain unclear. Therefore, the present study involved investigating the effects of KMUP‑1 on high glucose (HG) or TGF‑β1‑induced pro‑fibrotic proteins in mouse mesangial (MES13) cells, and the effects of KMUP‑1 on streptozotocin (STZ)‑induced diabetic rats...

The prevalence of severe obesity in both the general and the chronic kidney disease (CKD) populations continues to rise, with more than one-fifth of CKD patients in the United States having a body mass index of ≥35 kg/m(2). Severe obesity has significant renal consequences, including increased risk of end-stage renal disease (ESRD) and nephrolithiasis. Bariatric surgery represents an effective method for achieving sustained weight loss, and evidence from randomized controlled trials suggests that bariatric surgery is also effective in improving blood pressure, reducing hyperglycemia, and even inducing diabetes remission...

The prevalence of diabetes rapidly increased during the last decades in association with important changes in lifestyle. Diabetes and hyperglycemia are well-known for inducing deleterious effects on physiologic processes, increasing for instance cardiovascular diseases, nephropathy, retinopathy and foot ulceration. Interestingly, diabetes also impairs brain morphology and functions such as (1) decreased neurogenesis (proliferation, differentiation and cell survival), (2) decreased brain volumes, (3) increased blood-brain barrier leakage, (4) increased cognitive impairments, as well as (5) increased stroke incidence and worse neurologic outcomes following stroke...

Endoplasmic reticulum (ER) stress contributes to progression of diabetic nephropathy, which promotes end-stage renal failure in diabetic patients. This study was undertaken to investigate the actions of tempol and ramipril, pharmacological agents that target the consequences of NADPH oxidase, on diabetic nephropathy in a rat model of type 1 diabetes, with an emphasis on markers of ER stress. Male Sprague-Dawley rats were injected intravenously with a single bolus of streptozotocin (55mg/kg) to induce type 1 diabetes...
