Abstract
Anabolic-androgenic steroids (AAS) abuse is linked to some abnormalities in several tissues including the kidney. However, the precise molecular mediators involved in AAS-induced kidney disorder remain elusive. The main objective of the present study was to investigate the effect of Nandrolone decanoate on kidney injury alone or in combination with moderate exercise and its related mechanisms. Thirty-two male Wistar rats were subdivided randomly into four groups. control (Con), Nandrolone (10 mg/kg)(N), Exercise (Exe), Nandrolone + Exercise (N+Exe). RESULTS: After 6 weeks, nandrolone treatment led to a significant increase in functional parameters such as serum cystatin c, urea, creatinine, albuminuria and Albumin/ creatinine ratio indicating kidney dysfunction. Moreover, nandrolone treatment increased vacuolization, focal inflammation, hemorragia, cast formation fibrosis in the renal tissue of rats. miRNA-146a increased in kidney tissue after nandrolone exposure by using RT-PCR which may be considered idealtheranomiRNAcandidates for diagnosis and treatment. Western blotting indicated that IRAK1, TRAF6, TNF-α, NF-κB, iNOS and TGF-β protein expressions were considerably elevated in the kidneys of nandrolone treated rats. Moderate exercise could alleviate the renal dysfunction, histological abnormalities and aforementioned proteins. Our findings suggested that nandrolone consumption can cause damage to kidney tissue probably through miRNA-146a targeting IRAK1 and TRAF6 via activation of the NF-κB and TGF-β pathway. These results provide future lines of research in the identification of theranoMiRNAs related to nandrolone treatment, which can be ameliorated by moderate exercise.

Abstract
Renal ischemia/reperfusion (I/R) injury occurs in patients undergoing renal transplantation and with acute kidney injury and is responsible for the development of chronic allograft dysfunction as characterized by parenchymal alteration and fibrosis. Heparanase (HPSE), an endoglycosidase that regulates EMT and macrophage polarization, is an active player in the biological response triggered by ischemia/reperfusion (I/R) injury. I/R was induced in vivo by clamping left renal artery for 30 min in wt C57BL/6J mice. Animals were daily treated and untreated with Roneparstat (an inhibitor of HPSE) and sacrificed after 8 weeks. HPSE, fibrosis, EMT-markers, inflammation and oxidative stress were evaluated by biomolecular and histological methodologies together with the evaluation of renal histology and measurement of renal function parameters. 8 weeks after I/R HPSE was upregulated both in renal parenchyma and plasma and tissue specimens showed clear evidence of renal injury and fibrosis. The inhibition of HPSE with Roneparstat-restored histology and fibrosis level comparable with that of control. I/R-injured mice showed a significant increase of EMT, inflammation and oxidative stress markers but they were significantly reduced by treatment with Roneparstat. Finally, the inhibition of HPSE in vivo almost restored renal function as measured by BUN, plasma creatinine and albuminuria. The present study points out that HPSE is actively involved in the mechanisms that regulate the development of renal fibrosis arising in the transplanted organ as a consequence of ischemia/reperfusion damage. HPSE inhibition would therefore constitute a new pharmacological strategy to reduce acute kidney injury and to prevent the chronic pro-fibrotic damage induced by I/R.

Abstract
OBJECTIVES Inflammation plays an important role in the pathogenesis of diabetic nephropathy (DN). The aim of this study was to explore the anti-inflammatory role of PTY-2r (extracted from Pueraria tuberosa), on streptozotocin (STZ)-induced DN rats. METHODS Diabetes was induced by intraperitoneal injection of STZ (55mg/kg) in rats. After 60 days, the rats were randomly divided into three groups (n = 6/each group), namely DN control group 2, DN rats treated with PTY-2r at dose of 100 mg/100 g, group 3 and 50 mg/100 g, group 4, p.o for 20 days. The normal rats were chosen as a normal control (NC) group 1. KEY FINDINGS In DN rats, the expression of iNOS and inflammatory cytokines (IL-6 and TNF-α) was significantly increased. Raised expression of PKC-α was also found. As NF-kB is the main transcription factor for the inflammatory response-mediated progression of DN, variation in NF-kB expression and its activated phosphorylated derivative (pNF-kB) were also evaluated and increase in expression was obtained in the kidney of DN rats. PTY-2r treatment significantly reversed these changes in dose-dependent manner. CONCLUSIONS This study suggested that the nephroprotective effect of PTY-2r is possibly due to downregulation of PKC-α and NF-kB pathway and normalizing the expression of inflammatory cytokines and iNOS in the kidney of DN rats.

Abstract
Diabetic nephropathy (DN) is the most severe complication of diabetes and multiple factors are involved in the pathogenesis of DN. Among them, cadmium (Cd) acts as a risk factor inducing the occurrence of DN. The present study focused on investigating the protective role of caffeic acid phenethyl ester (CAPE), an active component of propolis from honeybee hives, against Cd-induced DN in mice based on ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS)and pattern recognition. Serum and urine biochemical indexes were detected and histopathological observation has been done to evaluate the damage of Cd on animals. Moreover, the global serum profiles of different groups were distinguished by UPLC-Q-TOF-MS and principal component analysis (PCA) were applied for group differentiation and marker selection. Moreover, the influence of Cd on the oxidative status in DN mice were also evaluated by assessing the parameters of oxidative stress, proinflammatory cytokines and antioxidant competence. As shown in the scores plots, the distinct clustering among controls, DN and CAPE groups were observed, significant changes in serum levels of LysoPC(18:1(11Z)), 2,3-dinor-8-iso-PGF2a, PS(18:1(9Z)/18:1(9Z)), DG(17:0/22:4 (7Z,10Z, 13Z, 16Z)/0:0) and Arachidonic acid(AA) were noted and identified as potential biomarkers, the effect of CAPE reverted them back to near normalcy. Further, It was observed a significant improvement in lipid peroxides (LPO) and protein carbonyls (PCO) levels in Cd-induced DN kidneys along with a significant decline in superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) levels, however, CAPE relieved these changes. In conclusion, the study suggested that the pathogenesis of DN caused by Cd probably owes to the perturbations of lipid metabolism and AA metabolism; CAPE seems to be effective agent and may be related to its potent antioxidant, anti-inflammatory properties and action as an Nrf2 activator.

Abstract
Increased vascular 20-HETE is associated with hypertension and activation of the renin-angiotensin system (RAS) through induction of vascular angiotensin-converting enzyme (ACE) expression. Cyp4a12tg mice, whose Cyp4a12-20-HETE synthase expression is under the control of a tetracycline (doxycycline, DOX) promoter, were used to assess the contribution of ACE/RAS to microvascular remodeling in 20-HETE-dependent hypertension. Treatment of Cyp4a12tg mice with DOX increased systolic blood pressure (SBP; 136 ± 2 vs. 102 ± 1 mmHg; P < 0.05), and this increase was prevented by administration of 20-HEDGE, lisinopril, or losartan. DOX-induced hypertension was associated with microvascular dysfunction and remodeling of preglomerular microvessels, which was prevented by 20-HEDGE, a 20-HETE antagonist, yet only lessened, but not prevented, by lisinopril or losartan. In ACE 3/3 mice, which lack vascular endothelial ACE, administration of 5α-dihydrotestosterone (DHT), a known inducer of 20-HETE production, increased SBP; however, the increase was about 50% of that in wild-type (WT) mice (151 ± 1 vs. 126 ± 1 mmHg). Losartan and 20-HEDGE prevented the DHT-induced increase in SBP in WT and ACE 3/3 mice. DHT treatment increased 20-HETE production and microvascular remodeling in WT and ACE 3/3 mice; however, remodeling was attenuated in the ACE 3/3 mice as opposed to WT mice (15.83 ± 1.11 vs. 22.17 ± 0.92 μm; P < 0.05). 20-HEDGE prevented microvascular remodeling in WT and ACE 3/3 mice, while losartan had no effect on microvascular remodeling in ACE 3/3. Taken together, these results suggest that RAS contributes to 20-HETE-mediated microvascular remodeling in hypertension and that 20-HETE-driven microvascular remodeling independent of blood pressure elevation does not fully rely on ACE activity in the vascular endothelium.

Abstract
Nitric oxide (NO) production is diminished in many patients with cardiovascular and renal disease. Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of NO synthesis, and elevated plasma levels of ADMA are associated with poor outcomes. Dimethylarginine dimethylaminohydrolase-1 (DDAH1) is a methylarginine-metabolizing enzyme that reduces ADMA levels. We reported previously that a DDAH1 gene variant associated with increased renal DDAH1 mRNA transcription and lower plasma ADMA levels, but counterintuitively, a steeper rate of renal function decline. Here, we test the hypothesis that reduced renal-specific ADMA metabolism protects against progressive renal damage. Renal DDAH1 is expressed predominately within the proximal tubule. A novel proximal tubule-specific Ddah1 knockout (Ddah1(PT-/-)) mouse demonstrated tubular cell accumulation of ADMA and lower NO concentrations, but unaltered plasma ADMA concentrations. Ddah1(PT-/-) mice were protected from reduced kidney tissue mass, collagen deposition, and profibrotic cytokine expression in two independent renal injury models: folate nephropathy and unilateral ureteric obstruction. Furthermore, a study of two independent kidney transplant cohorts revealed higher levels of human renal allograft methylarginine-metabolizing enzyme gene expression associated with steeper function decline. We also report an association among DDAH1 expression, NO activity, and uromodulin expression supported by data from both animal and human studies, raising the possibility that kidney DDAH1 expression exacerbates renal injury through uromodulin-related mechanisms. Together, these data demonstrate that reduced renal tubular ADMA metabolism protects against progressive kidney function decline. Thus, circulating ADMA may be an imprecise marker of renal methylarginine metabolism, and therapeutic ADMA reduction may even be deleterious to kidney function.

Abstract
Diabetic nephropathy is a serious microvascular complication for patients associated with diabetes mellitus. Recent studies have suggested that NF-κB is the main transcription factor for the inflammatory response mediated progression of diabetic nephropathy. Hence, the present study is hypothesized to explore the renoprotective nature of BAY 11-7082 an IκB phosphorylation inhibitor on Streptozotocin (STZ) induced diabetic nephropathy in Sprague-Dawley (SD) rats. Male SD rats were divided into five groups, group I sham control, group II drug control, group III diabetic control (STZ 50mg/kg), group IV and V are test drug groups to which a single dose of STZ 50mg/kg was injected initially and later received BAY 11-7082 1mg/kg and 3mg/kg, respectively from 5th to 8th week. Eight weeks after STZ injection, diabetic rats exhibited significant renal dysfunction, as evidenced by reduced creatinine clearance, increased blood glucose, urea nitrogen and creatinine, which were reversed to near normal by BAY 11-7082. BAY 11-7082 treated rats showed significant improvement in the decreased enzymatic antioxidant SOD, non-enzymatic antioxidant GSH levels, and elevated lipid peroxidation and nitric oxide levels as observed in the diabetic rats. BAY 11-7082 treatment was found to significantly recover kidney histological architecture in the diabetic rats. Altered levels of inflammatory cytokines like TNF-α, IL-1β, IL-6 and nuclear transcriptional factor subunit NF-κB p65 were reverted to the normal level upon treatment with BAY 11-7082. Our results suggest that by limiting the activation of NF-κB, thereby reducing the expression of inflammatory cytokines and by inhibiting the oxidative damage BAY 11-7082 protect the rats against diabetic nephropathy.

Abstract
Hepatocyte growth factor (HGF) is a potential therapeutic agent for diabetic nephropathy. The mechanisms for the renoprotective effect of HGF have been studied extensively, but antioxidant signalling of HGF in diabetic nephropathy is minimally understood. Our observations indicated that a nitrated guanine nucleotide, 8-nitroguanosine 3'5'-cyclic monophosphate (8-nitro-cGMP) diminished in high glucose (HG)-treated rat mesangial cells (RMC). However, HGF obviously lifted intracellular 8-nitro-cGMP level, which was accompanied by remarkably suppressed oxidative stress as evidenced by decreased reactive oxygen species and malondialdehyde levels and elevated glutathione level. Inhibitor of soluble guanylyl cyclase (sGC) NS-2028 and inhibitor of nitric oxide synthase (NOS) l-NMMA could block increased 8-nitro-cGMP level and repress oxidative stress by HGF. Accordingly, these two inhibitors abrogated HGF-induced nuclear accumulation of NF-E2 related factor 2 (Nrf2) and up-regulation of Nrf2 downstream glutamate-cysteine ligase catalytic subunit (GCLC) expression. In conclusion, HGF ameliorated HG-mediated oxidative stress in RMC at least in part by enhancing nitric oxide and subsequent 8-nitro-cGMP production.

Abstract
Hyperglycemia-mediated oxidative stress plays a crucial role in the progression of diabetic nephropathy. Hence, the present study was hypothesized to explore the renoprotective nature of resveratrol by assessing markers of oxidative stress, proinflammatory cytokines and antioxidant competence in streptozotocin-nicotinamide-induced diabetic rats. Oral administration of resveratrol to diabetic rats showed a significant normalization on the levels of creatinine clearance, plasma adiponectin, C-peptide and renal superoxide anion, hydroxyl radical, nitric oxide, TNF-α, IL-1β, IL-6 and NF-κB p65 subunit and activities of renal aspartate transaminase, alanine transaminase and alkaline phosphatase in comparison with diabetic rats. The altered activities of renal aldose reductase, sorbitol dehydrogenase and glyoxalase-I and elevated level of serum advanced glycation end products in diabetic rats were also reverted back to near normalcy. Further, resveratrol treatment revealed a significant improvement in superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase and glutathione reductase activities and vitamins C and E, and reduced glutathione levels, with a significant decline in lipid peroxides, hydroperoxides and protein carbonyls levels in diabetic kidneys. Similarly, mRNA and protein analyses substantiated that resveratrol treatment notably normalizes the renal expression of Nrf2/Keap1and its downstream regulatory proteins in the diabetic group of rats. Histological and ultrastructural observations also evidenced that resveratrol effectively protects the kidneys from hyperglycemia-mediated oxidative damage. These findings demonstrated the renoprotective nature of resveratrol by attenuating markers of oxidative stress in renal tissues of diabetic rats.

A conceptual framework for the molecular pathogenesis of progressive kidney disease. Pediatr Nephrol 2010; 25:2223-30. [PMID: 20352456 PMCID: PMC5558437 DOI: 10.1007/s00467-010-1503-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2010] [Revised: 02/22/2010] [Accepted: 02/23/2010] [Indexed: 01/26/2023]
Abstract
The data regarding the pathogenesis of progressive kidney disease implicate cytokine effects, physiological factors, and myriad examples of relatively nonspecific cellular dysfunction. The sheer volume of information being generated on this topic threatens to overwhelm our efforts to understand progression in chronic kidney disease or to derive rational strategies to treat it. Here, a conceptual framework is offered for organizing and considering these data. Disease is initiated by an injury that evokes a tissue-specific cellular response. Subsequent structural repair may be effective, or the new structure may be sufficiently changed that it requires an adaptive physiological response. If this adaptation is not successful, subsequent cycles of misdirected repair or maladaptation may lead to progressive nephron loss. To illustrate how this framework can be used to organize our approach to disease pathogenesis, the role of cytokines in proteinuria and progressive glomerular disease is discussed. Finally, this theoretical framework is reconsidered to examine its implications for the diagnosis and treatment of clinical conditions. Application of this schema could have significant relevance to both research inquiry and clinical practice.

Abstract
Cardiac failure secondary to myocardial fibrosis (MF) significantly contributes to death in Duchenne muscular dystrophy (DMD), a fatal form of muscle disease. In aging, the mdx mice, an animal model of DMD, MF is similar to that observed in humans. Nitric oxide-based therapy has been proposed to retard MF in DMD and a candidate is L-arginine (L-arg). In this study we evaluated the effects of long-term therapy with L-arg in the MF of mdx mice. mdx mice (6 months old) were treated with L-arg in drinking water. Control mdx mice received water only. After 15 months of treatment, hearts were stained with Masson's trichrome for analysis of MF and with hematoxilyn and eosin for analysis of inflammation and cardiomyocyte damage. We observed that MF was not affected (29.5 +/- 2.5% of MF area for control vs 31.4 +/- 2% for L-arginine-treated animals; P > 0.05). The density of inflammatory cells was reduced (169 +/- 12 cells/mm 2 in control vs 102 +/- 9 cells/mm 2 in L-arg-treated; P < 0.05). The present study shows that long-term administration of L-arg is not effective in retarding MF in mdx dystrophinopathy.
