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...

Glyburide is widely used for the treatment of type 2 diabetes mellitus. We studied the mechanisms involved in the disposition of glyburide and its pharmacologically active hydroxy metabolites, M1 and M2b; and evaluated their clinical pharmacokinetics and the potential role in glyburide-induced cholestasis employing physiologically based pharmacokinetic (PBPK) modeling. Transport studies of parent and metabolites in human hepatocytes and transfected cell systems imply hepatic uptake mediated by organic anion transporting polypeptides...

Chromosome 22q11.2 deletion is the most common chromosomal alteration associated with DiGeorge syndrome (DGS), even though this is not the only underlying cause of DGS. In rare patients, mutations in a single gene, TBX1, have been described resulting in a DGS phenotype. Recently, it has been reported that at least part of the TBX1 mutant phenotype is due to excessive bone morphogenetic proteins (BMP) signaling. Evidence suggests that miRNA may modulate the expression of critical T-box transcriptional regulators during midface development and Bmp-signaling...

Recent studies have shown that metal and metal oxide have a potential function in antitumor therapy. Our previous studies demonstrated that cuprous oxide nanoparticles (CONPs) not only selectively induce apoptosis of tumor cells in vitro but also inhibit the growth and metastasis of melanoma by targeting mitochondria with little hepatic and renal toxicities in mice. As a further study, our current research revealed that CONPs induced apoptosis of human melanoma stem cells (CD271(+/high) cells) in A375 and WM266-4 melanoma cell lines and could significantly suppress the expression of MITF, SOX10 and CD271 involved in the stemness maintenance and tumorigenesis of melanoma stem cells...

Oxidative stress is a critical factor in the pathophysiology of diabetic kidney disease. Previous study shows that hyperglycaemia aggravates renal injury through oxidative stress in diabetic model, and antioxidants have beneficial effect on diabetic kidney disease. However, the role of antioxidants in the progression of diabetic kidney disease is poorly understood. The aim of this study was to clarify whether zeaxanthin, an antioxidant, could ameliorate mesangial cell injury and if so, identify the related mechanism underlying this protective effect...

AIMS: The notion of an increased expression of SGLT2 in the kidney of patients with type 2 diabetes (T2DM) is based on a single ex vivo study of tubular cells harvested from the urine. DESIGN AND METHODS: We measured SGLT2 and SGLT1 expression in unaffected renal tissue from 19 T2DM patients and 20 age- and eGFR-matched nondiabetic subjects (CT) undergoing unilateral nephrectomy. Expression of SGLT2 and SGLT1 - and their cognate basolateral transporters GLUT2 and GLUT1 - was quantified by real-time and digital PCR; an affinity-purified antibody against human SGLT2 was used localize SGLT2 by immunohistochemistry...

BACKGROUND: Systemic lupus erythematosus (SLE), is a heterogeneous disease which predominantly affects young females (90%). SLE is associated with a shorter life expectancy than in the general population. Standardized mortality ratios (SMR) of 2.4 have been reported, which is comparable to diabetes. In modern societies cardiovascular disease (CVD) is the major cause of premature mortality. Accelerated atherosclerosis is generally assumed to be the underlying cause for SLE related CVD...

Diabetic kidney disease (DKD) has become the leading cause of end-stage renal disease worldwide and is associated with glomerular mesangial cell (MC) proliferation and excessive extracellular matrix (ECM) production. Klotho can attenuate renal fibrosis in part by inhibiting TGF-β1/Smad3 signaling in DKD. Early growth response factor 1 (Egr-1) has been shown to play a key role in renal fibrosis in part by facilitating the formation of a positive feedback loop involving TGF-β1. However, whether Klotho down-regulates Egr-1 by inhibiting TGF-β1/Smad3 signaling in DKD is unclear...

Hyperlipidemia is a risk factor for initiation and progression of diabetic nephropathy but the metabolic pathways altered in the diabetic kidney in a context of hyperlipidemia remain incompletely described. Assuming that changes in urine composition reflect the alteration of renal metabolism and function, we analyzed the urine metabolite composition of diabetic (streptozotocin-treatment) and control (non diabetic) ApoE-/- mice fed a high cholesterol diet using targeted quantitative metabolomics. Urine metabolome was also compared to the plasma metabolome of the same animals...

In patients with type 2 diabetes mellitus (T2DM), the main cause of morbidity and mortality is cardiovascular (CV) disease. Diabetic kidney disease, which develops in approximately 40% of patients with T2DM, further increases the risk of CV-related morbidity and mortality. The sodium glucose co-transporter 2 (SGLT2) inhibitor empagliflozin, which provides effective glycaemic control as either monotherapy or as an add-on to other glucose-lowering agents in patients with T2DM, was also shown to improve CV and renal outcomes in the large, randomised, placebo-controlled EMPA-REG OUTCOME trial in patients with T2DM at high risk of CV events...

BACKGROUND: Diabetic nephropathy is one of the most important complications in patients with diabetes mellitus. Main steps crucial for the pathogenesis of diabetic nephropathy involve amongst others the modulation of cell signaling via AMP-activated kinase (AMPK) and mammalian target of rapamycin (mTOR), reactive oxygen generation, and endoplasmic reticulum stress under diabetic or hyperglycemic conditions. These processes mediate increased loss of renal cells, such as podocytes, which consequentially leads to renal damage and loss of renal functions, such as structural integrity and glomerular filtration in diabetic nephropathy...

BACKGROUND: Although sodium glucose cotransporter 2 (SGLT2) inhibitors have many beneficial effects for type 2 diabetes, including decreased cardiovascular death, recent reports that they increased glucagon through SGLT2 inhibition raised some concern. Troglitazone, Peroxisome proliferator-activated receptor γ (PPAR-γ) agonist, was reported to increase SGLT2 in renal proximal tubule cells, but its role on pancreatic alpha cells have not been reported. We investigated the effect of troglitazone on SGLT2 expression in alpha cells and subsequent glucagon regulation in hyperglycemia...

Despite the high prevalence of acute kidney injury (AKI) and its association with increased morbidity and mortality, therapeutic approaches for AKI are disappointing. This is largely attributed to poor understanding of the pathogenesis of AKI. Heparanase, an endoglycosidase that cleaves heparan sulfate, is involved in extracellular matrix turnover, inflammation, kidney dysfunction, diabetes, fibrosis, angiogenesis and cancer progression. The current study examined the involvement of heparanase in the pathogenesis of ischemic reperfusion (I/R) AKI in a mouse model and the protective effect of PG545, a potent heparanase inhibitor...

Autophagy is a highly conserved, physiological, catabolic process, involving the lysosomal degradation of cytosolic components, including macromolecules (such as proteins and lipids) and cytosolic organelles. Autophagy is believed to be essential for the maintenance of cellular homeostasis, for a number of fundamental biological activities, and an important component of the complex response of cells to multiple forms of stress. Autophagy is involved in the pathogenesis of a number of clinically important disorders but, until recently, little was known about its connection to kidney diseases...
