Small non-coding RNAs including microRNAs (miRNAs) have been recently recognized as important regulators of gene expression. MicroRNAs play myriads of roles in physiological processes as well as in the pathogenesis of a number of diseases by translational repression or mRNA destabilization of numerous target genes. The miR-106b-25 cluster is highly conserved in vertebrates and consists of three members including miR-106b, miR-93 and miR-25. MiR-106b and miR-93 share the same seed sequences; however, miR-25 has only a similar seed sequence resulting in different predicted target mRNAs...

Among several pathological mechanisms involved in diabetic nephropathy, oxidative stress, inflammation, and apoptosis play a prominent role. Fenofibrate, a peroxisome proliferator-activated receptor-α (PPAR-α) agonist, has markedly improved oxidative stress and inflammatory responses, but there is no evidence about its effects on interleukin-18 (IL-18), NADPH oxidase type 4 (NOX-4), and p53 expression in diabetic kidneys. The aim of this study was to evaluate possible effects of fenofibrate on improving the underlying mechanisms of diabetic nephropathy...

Nephropathy is a serious complication of metabolic syndrome (MS), a global epidemic disorder. This study was undertaken to investigate the actions of diosmin and crocin, two natural ingredients, on diabetic nephropathy in a rat model of MS and the underlying mechanism(s). Metabolic syndrome was induced by the addition of 10% fructose to drinking water and placing the rats on high-salt diet for 16 weeks. Diosmin and Crocin were orally administrated daily for 10 weeks starting at week 6. At the end of study, arterial blood pressure was non-invasively recorded...

Diabetic nephropathy is the leading cause of end-stage renal disease in the world. Although recent development of sodium-glucose cotransporter (SGLT) 2 inhibitors offers a new antidiabetic therapeutic strategy, it remains unclear whether such treatments are beneficial for limiting the progression of type 2 diabetic overt nephropathy. This study examined the effect of the SGLT2 inhibitor ipragliflozin on the progression of nephropathy in uninephrectomized KK/Ay type 2 diabetic mice, which exhibit not only typical diabetic symptoms such as hyperglycemia, hyperinsuemia, glucose intolerance, insulin resistance, hyperlipidemia, inflammation, and obesity, but also moderate hypertension and overt nephropathy with decline in renal function...

Paeoniflorin is the main bioactive components of the root of P.lactiflora Pall., and has been widely used as an anti-inflammation and immunomodulatory agent. However, the effect and mechanisms of Paeoniflorin in diabetic nephropathy (DN) remains to be elucidated. In the present study, streptozotocin (STZ)-induced type 1 diabetic mice model was used to investigate the protective effect of Paeoniflorin and the role of the Janus kinase (JAK) 2/signal transducer (STAT) 3 signaling pathway on DN. After treatment with Paeoniflorin at a dose of 25, 50 and 100 mg/kg once a day for 12 weeks, both the functional and histological damage to diabetic mice kidney had been attenuated significantly...

Soluble guanylate cyclase (sGC), a key signal-transduction enzyme, increases the conversion of guanosine-5'-triphosphate (GTP) to cyclic guanosine-3',5'-monophosphate (cGMP) upon binding of nitric oxide (NO). Endothelial dysfunction and/or reduced NO signaling have been implicated in cardiovascular disease pathogenesis and complications of diabetes, and have been associated with other disease states and aging. sGC stimulators are small-molecule drugs that bind sGC and enhance NO-mediated cGMP signaling. The pharmacological characterization of IW-1973, a novel clinical-stage sGC stimulator, is described...

Inflammation and lipid disorders play crucial roles in synergistically accelerating the progression of diabetic nephropathy (DN). In this study we investigated how inflammation and lipid disorders caused tubulointerstitial injury in DN in vivo and in vitro. Diabetic db/db mice were injected with 10% casein (0.5 mL, sc) every other day for 8 weeks to cause chronic inflammation. Compared with db/db mice, casein-injected db/db mice showed exacerbated tubulointerstitial injury, evidenced by increased secretion of extracellular matrix (ECM) and cholesterol accumulation in tubulointerstitium, which was accompanied by activation of the CXC chemokine ligand 16 (CXCL16) pathway...

BACKGROUND: Diabetic nephropathy is the leading cause of end-stage renal disease. Hyperglycemia, oxidative stress, and inflammation are some of the mechanisms involved in renal damage. Anogeissus acuminata (AA) is used in India as an antidiabetic agent and has potent antioxidant activity. However, it has never been evaluated for its effect on diabetic nephropathy. Hence, in the present study we aimed to evaluate its effect on streptozotocin-induced diabetes mellitus and its renal complications...

Accumulating evidence has shown that macrophages play a vital role in development and pathogenesis of diabetic nephropathy (DN) by secreting inflammatory cytokines. Although Bruton's tyrosine kinases (Btk) is a biologically important molecule implicated in immune regulation, the role of Btk in high glucose (HG)-stimulated inflammatory response in macrophages and the mechanism involved need further investigation. In our study, we used bone marrow-derived macrophages (BMMs) to investigate the involvement of Btk on HG-induced inflammatory cytokines expression and to explore the underlying mechanisms...

Diabetic kidney disease, commonly termed diabetic nephropathy (DN), is the most common cause of end-stage kidney disease (ESKD) worldwide. The characteristic histopathology of DN includes glomerular basement membrane thickening, mesangial expansion, nodular glomerular sclerosis, and tubulointerstitial fibrosis. Diabetes is associated with a number of metabolic derangements, such as reactive oxygen species overproduction, hypoxic state, mitochondrial dysfunction, and inflammation. In the past few decades, our knowledge of DN has advanced considerably although much needs to be learned...

Background & objectives: Uromodulin, a UMOD gene encoded glycoprotein is synthesized exclusively in renal tubular cells and released into urine. Mutations lead to uromodulin misfolding and retention in the kidney, where it might stimulate cells of immune system to cause inflammation and progression of kidney disease. Genome-wide association studies (GWAS) have identified UMOD locus to be associated with hypertension and diabetic nephropathy (DN). In this study, we investigated the association between rs4293393 variation in UMOD gene and susceptibility to kidney disease in individuals with type 2 diabetes mellitus (T2DM)...

Oxidative damage, inflammation and apoptosis play significant roles in diabetic nephropathy. Previous studies demonstrated anti-inflammatory and anti-oxidative effects of crocin, but there is no evidence about its effects on IL-18, NOX-4, and p53 expression in diabetic kidneys. The aim of this study was to evaluate possible effects of crocin on improving main mechanisms underlying diabetic nephropathy. Male Wistar rats were randomly divided into four separate groups as normal (C), normal treated (CC), diabetic (D), and diabetic treated (DC) (n = 6)...

Oxidative stress resulting from excessive production of reactive oxygen species (ROS) or impaired antioxidant defenses is closely related to the development of diabetic vascular complications, including nephropathy and atherosclerosis. Chronic activation of Janus kinase/Signal transducer and activator of transcription (JAK/STAT) signaling pathway contributes to diabetic complications by inducing expression of genes involved in cell proliferation, fibrosis, inflammation, and oxidative stress. Suppressors of cytokine signaling (SOCS) family of endogenous JAK/STAT regulators is an attractive target for therapeutic intervention...

Development of diabetic nephropathy (DN) is directly linked to oxidative stress and inflammation. In this context, inflammatory and oxidative markers have gained much attention as targets for therapeutic intervention. We studied the effect of zingerone in a streptozotocin/high fat diet (STZ/HFD)-induced type 2 diabetic Wistar rat model. Zingerone also known as vanillyl acetone is a pharmacologically active compound present usually in dry ginger. STZ/HFD caused excessive increase in ROS and inflammation in experimental animals...
