Ameliorative effect of ursolic acid on renal fibrosis in adenine-induced chronic kidney disease in rats.

Ameliorative effect of ursolic acid on renal fibrosis in adenine-induced chronic kidney disease in rats. Biomed Pharmacother. 2018 May;101:972-980 Authors: Thakur R, Sharma A, Lingaraju MC, Begum J, Kumar D, Mathesh K, Kumar P, Singh TU, Kumar D Abstract Ursolic acid (UA), an ursane-type pentacyclic triterpenoid commonly found in apple peels and holy basil has been shown to possess many beneficial effects. Renal fibrosis is a complication of kidney injury and associated with increased risk of morbidity and mortality. In our previous investigation, a lupane-type pentacyclic triterpenoid, betulinic acid (BA) was found to have protective effect on chronic kidney disease (CKD) and renal fibrosis. This prompted us to explore the therapeutic value of UA, a chemically related compound to BA in CKD. CKD was induced by feeding adenine with the feed at a concentration of 0.75% for 28 days. UA at the dose rate of 30 mg/kg in 0.5% carboxy methyl cellulose (CMC) was administered by oral route, simultaneously with adenine feeding for 28 days. Adenine feeding increased the kidney weight to body weight index, decreased the kidney function due to injury as indicated by increased markers like serum urea, uric acid, creatinine, cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) and initiated the fibrotic response in kidney by increasing the profibrotic proteins viz. transforming growth factor-beta (TGF-β), connective tissue growth factor (CTGF), fibron...

In this study, we explored the molecular mechanism of IR with chronic renal failure (CRF) and interventions to alleviate IR in patients with CRF. MATERIAL AND METHODS In vivo and in vitro models of CRF were established by 5/6 nephrectomy and urea stimulation C2C12 cells, respectively. Based on the CRF model, angiotensin II (Ang II) and valsartan groups were established to observe the effect of drug intervention on IR. Western blot assays were performed to detect the expression and phosphorylation of IRS-1 and Akt, which are 2 critical proteins in the insulin signaling pathway. RESULTS Both urea stimulation and 5/6 nephrect...

Authors: S Herath HMA, Kawakami T, Nagasawa S, Serikawa Y, Motoyama A, Chaminda GGT, Weragoda SK, Yatigammana SK, Amarasooriya AAGD Abstract Chronic kidney disease of unknown etiology (CKDu) is spreading gradually in Sri Lanka. In the current research, 1,435 well water samples from all 25 districts of Sri Lanka, 91 rice samples, and 84 human urine samples from both CKDu-endemic and non-endemic areas in Sri Lanka were analyzed for arsenic, cadmium, lead, and chromium to detect whether toxic elements could be a cause of CKDu. The liver-type fatty acid binding protein (L-FABP) concentration and arsenic, cadmium, lead,...

However, it is unclear whether intensive lowering of systolic blood pressure increases the incidence of c...

Authors: Ha KH, Kim B, Shin HS, Lee J, Choi H, Kim HC, Kim DJ Abstract BACKGROUND AND OBJECTIVES: To compare cardiovascular disease (CVD) risk associated with 5 different dipeptidyl peptidase-4 inhibitors (DPP-4is) in people with type 2 diabetes. METHODS: We identified 534,327 people who were newly prescribed sitagliptin (n=167,157), vildagliptin (n=67,412), saxagliptin (n=29,479), linagliptin (n=220,672), or gemigliptin (n=49,607) between January 2013 and June 2015 using the claims database of the Korean National Health Insurance System. A Cox proportional hazards model was used to estimate hazard ratios (HRs)...

This study prospectively examined the association between these eGFR values and all-cause mortality during a 12-year observational period in a community-based population. Methods and Results: The subjects of this study were 1312 participants undergoing a health checkup, aged ≥40 years. In the total population, the mean eGFR values (mL·min-1·1.73 m-2) were 81.5 for eGFRcreat, 78.1 for eGFR-EPI, and 76.6 for eGFRcys. There were 141 deaths during the observation period, and the area under the receiver operating characteristic curve for predicting mortality was 0.59 for eGFRcreat, 0.67 for eGFR-EPI,...

Abstract Organ shortage has long been an obstacle to transplant procedures. As acceptance of aging kidneys from expanded criteria donors increases, the long-term outcomes of renal allografts could be unsatisfactory. The klotho gene, which is known as an antiaging gene that is highly expressed in kidneys, is closely associated with chronic kidney disease and acute kidney injury. Results from existing literature have shown a tendency to support Klotho as a renal protective protein owing to its pleiotropic effects. However, few data are available on Klotho in renal transplant. Whether Klotho serves the same purposes ...

This study suggests that prenatal hypoxia selectively disrupts collecting duct patterning through altered Wnt/β-catenin and retinoic acid signaling and this results in impaired function in male mouse offspring in later life.

Authors: Tong L, Adler S Abstract Chronic kidney disease (CKD) is a frequent complication of type 2 diabetes mellitus (T2DM) and elevates individuals' risk for cardiovascular disease, the leading cause of morbidity and mortality in T2DM. Achieving and maintaining tight glycemic control is key to preventing development or progression of CKD; however, improving glycemic control may be limited by effects of renal impairment on the efficacy and safety of T2DM treatments, necessitating dosing adjustments and careful evaluation of contraindications. Understanding the treatment considerations specific to each class of T2D...
