Diabetic nephropathy (DN) is a serious complication of diabetes mellitus, and its prevalence has been increasing in developed countries. Diabetic nephropathy has become the most common single cause of end-stage renal disease worldwide. Oxidative stress and inflammation factors are hypothesized to play a role in the development of late diabetes complications. Chronic hyperglycemia increases oxidative stress, significantly modifies the structure and function of proteins and lipids, and induces glycoxidation and peroxidation...

Diabetic nephropathy is one of the major microvascular complications of diabetes mellitus which ultimately gives rise to cardiovascular diseases. Oxidative stress produced by prolonged hyperglycaemia and chronic renal inflammation are the two key players in the development and progression of diabetic nephropathy. NF-kB-mediated inflammatory cascade is a strong contributor to the renovascular inflammation in diabetic nephropathy. Here, we studied the effects of piceatannol, a potent NF-kB inhibitor, on various oxidative stress markers and diabetic renal inflammatory pathway in rat induced by alloxan...

Diabetic nephropathy (DN) is a serious complication of diabetes mellitus, and persistent inflammation in circulatory and renal tissues is an important pathophysiological basis for DN. The essence of the microinflammatory state is the innate immune response, which is central to the occurrence and development of DN. Members of the inflammasome family, including both "receptors" and "regulators", are key to the inflammatory immune response. Nucleotide binding and oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) and other inflammasome components are able to detect endogenous danger signals, resulting in activation of caspase-1 as well as interleukin (IL)-1β, IL-18 and other cytokines; these events stimulate the inflammatory cascade reaction, which is crucial for DN...

Triptolide has been shown to have anti-inflammatory properties. miRNAs have emerged as important regulators of DN. However, the role of miRNAs in inflammation regulation during DN development is poorly understood. In this study, we investigated the effects of the association between miRNAs and triptolide on inflammation in DN. We found that triptolide significantly inhibits the inflammatory reactions of DN in rats, and miR-224-3p is selectively upregulated more than 2 fold in NRK-52E cells treated with triptolide compared to the cells without treatment...

Diabetic nephropathy (DN) is a major cause of morbidity and mortality in diabetic patients and a leading cause of end-stage renal disease (ESRD). Degenerative changes such as glomerular hypertrophy, hyperfiltration, widening of basement membranes, tubulointerstitial fibrosis, glomerulosclerosis and podocytopathy manifest in various degrees of proteinuria in DN. One of the key mechanisms implicated in the pathogenesis of DN is non-enzymatic glycation (NEG). NEG is the irreversible attachment of reducing sugars onto free amino groups of proteins by a series of events, which include the formation of Schiff's base and an Amadori product to yield advanced glycation end products (AGEs)...

Hydrogen sulfide has gained recognition as the third gaseous signaling molecule after nitric oxide and carbon monoxide. This review surveys the emerging role of H2S in mammalian renal system, with emphasis on both renal physiology and diseases. H2S is produced redundantly by four pathways in kidney, indicating the abundance of this gaseous molecule in the organ. In physiological conditions, H2S was found to regulate the excretory function of the kidney possibly by the inhibitory effect on sodium transporters on renal tubular cells...

Oxidative stress contributes to the pathogenesis of diabetic nephropathy (DN). Nuclear factor erythroid 2-related factor 2 (NRF2) plays a key role in cellular defense against oxidative stress. NRF2 activators have shown promising preventive effects on DN. Sodium butyrate (NaB) is a known activator of NRF2. However, it is unknown whether NRF2 is required for NaB protection against DN. Therefore, streptozotocin-induced diabetic C57BL/6 Nrf2 knockout and their wild-type mice were treated in the presence or absence of NaB for 20 weeks...

Microvascular complications are the leading causes of acquired blindness, end-stage renal failure, and varieties of neuropathy associated with diabetes. Asymmetric dimethylarginine (ADMA), an endogenous nitric oxide synthase inhibitor, is involved in endothelial dysfunction, oxidative stress, and inflammation associated with the progression of diabetic microvascular complications. Elevated ADMA has been detected in experimental animals and patients with diabetic microangiopathy like retinopathy, nephropathy, and neuropathy...

BACKGROUND: Endocan is a newly identified proteoglycan released from endothelium, stimulating angiogenesis and when increased, indicates endothelial activation (inflammation). Our aim was to examine the association between serum endocan levels and urine albumin-creatinine ratio (UACR). METHOD: One hundred and thirty-seven patients with type 2 diabetes mellitus and normal serum creatinine who had no co-morbidities other than hypertension, diabetic nephropathy, retinopathy, or neuropathy were divided into normoalbuminuria (G1), microalbuminuria (G2), and macroalbuminuria (G3) groups and compared cross-sectionally regarding serum endocan levels...

There is accumulating evidence that RAS inhibitors not only reduce blood pressure, but also exert pleiotropic effects, including a renoprotective effect, amelioration of insulin resistance, reduction in onset of diabetes, and suppression of cardiovascular remodelling,. However, the definite benefit of RAS inhibition in treatment of hypertension with CKD or DM is not conclusive. We previously performed the OlmeSartan and Calcium Antagonists Randomized (OSCAR) study comparing the preventive effect of high-dose ARB therapy versus ARB plus CCB combination therapy on cardiovascular morbidity and mortality in 1164 Japanese elderly hypertensive patients with baseline type 2 diabetes and/or CVD (Am J Med (2012))...

Diabetic nephropathy (DN) is the leading cause of end-stage kidney disease worldwide but current treatments remain suboptimal. The role of inflammation in DN has only recently been recognized. It has been shown that the NLRP3-inflammasome contributes to DN development by inducing interleukin (IL)-1β processing and secretion. In an effort to understand other IL-1β activating mechanism during DN development, we examined the role of the NLRC4-inflammasome in DN and found that NLRC4 is a parallel mechanism, in addition to the NLRP3-inflammasome, to induce pro-IL-1β processing and activation...

Diabetic nephropathy (DN), a common complication associated with type 1 and type 2 diabetes mellitus (DM), characterized by glomerular mesangial expansion, inflammation, accumulation of extracellular matrix (ECM) protein, and hypertrophy, is the major cause of end-stage renal disease (ESRD). Increasing evidence suggested that p21-dependent glomerular and mesangial cell (MC) hypertrophy play key roles in the pathogenesis of DN. Recently, posttranscriptional modifications (PTMs) have uncovered novel molecular mechanisms involved in DN...
