Abstract
The clinical use of cyclosporin A (CsA) has led to significant advances and achievements in the field of transplantation and immune diseases. However, the nephrotoxicity of CsA is a major concern in current immunosuppression regimens. CsA causes abnormal kidney function while treating kidney disease, causing problems for clinicians and patients. Evidence of CsA nephrotoxicity is almost always present in transplant recipients after long-term CsA administration (up to 10 years), and similar phenomena occur with other calcineurin inhibitors. In this review, we summarize the mechanisms and influencing factors of CsA for the treatment of primary nephrotic syndrome. The mechanisms of CsA nephrotoxicity, clinical-pathological features, diagnosis, prevention strategies, and risk factors are summarized. We discuss the correlates and mechanisms of the switch between kidney disease prevention and nephrotoxicity of CsA to better understand the function of CsA in the kidney and to provide a basis for the prevention and treatment of CsA nephrotoxicity.

Abstract
The Hippo signaling pathway is involved in cell growth, proliferation, and apoptosis, and it plays a key role in regulating organ size, tissue regeneration, and tumor development. The Hippo signaling pathway also participates in the occurrence and development of various human diseases. Recently, many studies have shown that the Hippo pathway is closely related to renal diseases, including renal cancer, cystic kidney disease, diabetic nephropathy, and renal fibrosis, and it promotes the transformation of acute kidney disease to chronic kidney disease (CKD). The present paper summarizes and analyzes the research status of the Hippo signaling pathway in different kidney diseases, and it also summarizes the expression of Hippo signaling pathway components in pathological tissues of kidney diseases. In addition, the present paper discusses the positive therapeutic significance of traditional Chinese medicine (TCM) in regulating the Hippo signaling pathway for treating kidney diseases. This article introduces new targets and ideas for drug development, clinical diagnosis, and treatment of kidney diseases.

Abstract
Kidney stones are one of the most common renal pathologies. While emerging evidence has implicated a potential association between kidney stones and upper urinary tract cancers (including renal cancer), there is limited understanding as to the common underlying biological pathways functionally linking the etiology of kidney stone formation and the incidence, development, and progression of urinary tract cancers. From a clinical perspective, kidney stone disease can be a barrier to oncologic care due to renal obstruction. From the epidemiological perspective, risk factors associated with both conditions include smoking, alcohol consumption, diet, and gender. Herein, we review the association between renal calculi and malignancy of the upper urinary tract and discuss the current understanding of (a) potential shared mechanisms, and (b) the impact this has on shared therapeutic management of both conditions.

Recent Advances on Biomarkers of Early and Late Kidney Graft Dysfunction. Int J Mol Sci 2020; 21:ijms21155404. [PMID: 32751357 PMCID: PMC7432796 DOI: 10.3390/ijms21155404] [Citation(s) in RCA: 39] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 07/22/2020] [Accepted: 07/27/2020] [Indexed: 02/06/2023] Open
Abstract
New biomarkers of early and late graft dysfunction are needed in renal transplant to improve management of complications and prolong graft survival. A wide range of potential diagnostic and prognostic biomarkers, measured in different biological fluids (serum, plasma, urine) and in renal tissues, have been proposed for post-transplant delayed graft function (DGF), acute rejection (AR), and chronic allograft dysfunction (CAD). This review investigates old and new potential biomarkers for each of these clinical domains, seeking to underline their limits and strengths. OMICs technology has allowed identifying many candidate biomarkers, providing diagnostic and prognostic information at very early stages of pathological processes, such as AR. Donor-derived cell-free DNA (ddcfDNA) and extracellular vesicles (EVs) are further promising tools. Although most of these biomarkers still need to be validated in multiple independent cohorts and standardized, they are paving the way for substantial advances, such as the possibility of accurately predicting risk of DGF before graft is implanted, of making a “molecular” diagnosis of subclinical rejection even before histological lesions develop, or of dissecting etiology of CAD. Identification of “immunoquiescent” or even tolerant patients to guide minimization of immunosuppressive therapy is another area of active research. The parallel progress in imaging techniques, bioinformatics, and artificial intelligence (AI) is helping to fully exploit the wealth of information provided by biomarkers, leading to improved disease nosology of old entities such as transplant glomerulopathy. Prospective studies are needed to assess whether introduction of these new sets of biomarkers into clinical practice could actually reduce the need for renal biopsy, integrate traditional tools, and ultimately improve graft survival compared to current management.

Abstract
Calcineurin inhibitors (CNI) are the pillars of immunosuppression in transplantation. However, they display a potent nephrotoxicity whose mechanisms remained widely unsolved. We used an untargeted quantitative proteomic approach (iTRAQ technology) to highlight new targets of CNI in renal proximal tubular cells (RPTCs). CNI-treated RPTCs proteome displayed an over-representation of actin-binding proteins with a CNI-specific expression profile. Cyclosporine A (CsA) induced F-actin remodeling and depolymerization, decreased F-actin-stabilizing, polymerization-promoting cofilin (CFL) oligomers, and inhibited the G-actin-regulated serum response factor (SRF) pathway. Inhibition of CFL canonical phosphorylation pathway reproduced CsA effects; however, S3-R, an analogue of the phosphorylation site of CFL prevented the effects of CsA which suggests that CsA acted independently from the canonical CFL regulation. CFL is known to be regulated by the Na+/K+-ATPase. Molecular docking calculations identified two inhibiting sites of CsA on Na+/K+-ATPase and a 23% decrease in Na+/K+-ATPase activity of RPTCs was observed with CsA. Ouabain, a specific inhibitor of Na+/K+-ATPase also reproduced CsA effects on actin organization and SRF activity. Altogether, these results described a new original pathway explaining CsA nephrotoxicity.

Abstract
BACKGROUND Renin-angiotensin system (RAS) blockade during nephrogenesis causes a broad range of renal mal-development. Here, we hypothesized that disruption of renal lymphangiogenesis may contribute to tubulointerstitial alterations after RAS blockade during kidney maturation. METHODS Newborn rat pups were treated with enalapril (30 mg/kg/day) or vehicle for 7 days after birth. Lymphangiogenesis was assessed via immunostaining and/or immunoblots for vascular endothelial growth factor (VEGF)-C, VEGF receptor (VEGFR)-3, Podoplanin, and Ki-67. The intrarenal expression of fibroblast growth factor (FGF)-1, FGF-2, FGF receptor (R)-1, α-smooth muscle actin (α-SMA), and fibroblast-specific protein (FSP)-1 was also determined. Sirius Red staining was performed to evaluate interstitial collagen deposition. RESULTS On postnatal day 8, renal lymphangiogenesis was disrupted by neonatal enalapril treatment. The expression of podoplanin and Ki-67 decreased in enalapril-treated kidneys. While the expression of VEGF-C was decreased, the levels of VEGFR-3 receptor increased following enalapril treatment. Enalapril treatment also reduced the renal expression of FGF-1, FGF-2, and FGFR-1. Enalapril-treated kidneys exhibited profibrogenic properties with increased expression of α-SMA and FSP-1 and enhanced deposition of interstitial collagen. CONCLUSION Enalapril treatment during postnatal renal maturation can disrupt renal lymphangiogenesis along with tubulointerstitial changes, which may result in a pro-fibrotic environment in the developing rat kidney.

Abstract
Nephrotoxicity is a serious side effect for the immunosuppressant drug cyclosporine A(CSA). In this study, we tested the hypothesis that administration of calcium channel blockers such as verapamil or nifedipine ameliorates renal CSA-induced renal dysfunction. Furthermore, our study investigates the roles of inflammatory, oxidative, and fibrotic pathways in CSA-induced renal dysfunction. Six groups of male rats ( n = 6/group) were used and received one of the following treatments for seven consecutive days: vehicle (Cremophor EL ip), CSA (25 mg·kg-1·day-1 ip), verapamil (2 mg·kg-1·day-1 ip), nifedipine (3 mg·kg-1·day-1 ip), CSA in the presence or absence of either verapamil, or nifedipine. Biochemical and histomorphometric analyses showed that rats treated with CSA exhibited clear signs of nephrotoxicity that included 1) proteinuria and elevations in serum creatinine and blood urea nitrogen, 2) mesangial expansion, 3) increases in glomerular and tubular type IV collagen expression, and 4) increases in the glomerulosclerosis and tubulointerstitial fibrosis indices. Although the single administration of nifedipine or verapamil had no significant effect on renal pathology, or its biochemical and physiological function, the concurrent use of either calcium channel blockers significantly and equipotently ameliorated the biochemical, morphological, and functional derangements caused by CSA. More importantly, we report that the oxidative (reactive oxygen species production, NADPH-oxidase activity, and dual oxidase 1/2 levels), fibrotic (transforming growth factor-β1 expression), and inflammatory (NF-κB expression) manifestations of renal toxicity induced by CSA were significantly reversed upon administration of nifedipine or verapamil. Together, these results highlight the efficacy of calcium channel-blocking agents in attenuating CSA-induced nephrotoxicity and predisposing biochemical and molecular machineries.

Abstract
Background Nephrotoxicity of calcineurin inhibitors (CNIs) is the major concern for long-term allograft survival despite its predominant role in current immunosuppressive regime after renal transplantation. CNI nephrotoxicity is multifactorial with demographic, environmental, and pharmacogenetic flexibility, whereas studies indicating risk factors for CNI nephrotoxicity obtained incomplete or conflicting results. Methods A systematic review and meta-analysis of risk factors for CNI nephrotoxicity was performed on all retrieved studies through a comprehensive research of network database. Data were analyzed by Review Manager 5.2 with heterogeneity assessed using the Cochrane Q and I2 tests. CNI nephrotoxicity was primarily indicated with protocol biopsy or index-based clinical diagnosis, and the secondary outcome was defined as delayed graft function. Results Twelve observational studies containing a total of 2,849 cases were identified. Donor age (odds ratio [OR], 1.01; 95% CI, 1.01-1.03; p=0.02), recipient zero-time arteriosclerosis (OR, 1.44; 95% CI, 1.04-1.99; p=0.03), and CYP3A5*3/*3 genotype (OR, 2.80; 95% CI, 2.63-2.98; p=0.00) were confirmed as risk factors for CNI nephrotoxicity. Subgroup and sensitivity analysis claimed donor age as a significant contributor in Asian and Caucasian areas. Conclusion Older donor age, recipient zero-time arteriosclerosis, and CYP3A5*3/*3 genotype might add up the risk for CNI nephrotoxicity, which could be interpreted into a robust biomarker system.

Abstract
Cyclosporine A (CsA), a widely used immunosuppressive drug in organ transplantation and autoimmune disorders, frequently induces renal damage and fibrosis. Recent evidence has implicated epithelial-mesenchymal transition (EMT) in CsA-induced nephrotoxicity. Microarray analysis disclosed miR-181c as the microRNA most dramatically repressed by CsA. Downregulation of miR-181c expression at the transcriptional level by CsA is dependent on the transcription factor Nrf2. miR-181c mimics or inhibitors attenuate or aggravate CsA-induced EMT gene changes, respectively. Importantly, in Nrf2-/- mice, CsA-induced renal damage, fibrosis, and EMT gene changes are restored by miR-181c mimics. Mechanistically, we identified Notch2 as a potential target of miR-181c. Collectively, our data support the notion that miR-181c may serve as an important factor for protecting renal tissues from CsA-induced nephrotoxicity.

Abstract
Modelling methods that are commonly used to establish a murine model of hypoxic renal interstitial fibrosis mainly includes 5/6 nephrectomy, unilateral ureteral obstruction and cyclosporin A (CsA)-induced renal interstitial fibrosis. The first two methods are technically challenging and unsuitable for clinical practice; thus, CsA induction is more promising. A previously introduced model of CsA-induced renal interstitial fibrosis involves the subcutaneous injection of CsA combined with a 0.01% low-sodium diet. The aim of this study was to provide a modified approach to this model by replacing the subcutaneous injection with gavage and the low-sodium diet with furosemide. From the gross morphology of kidney; the micro-specimens which were stained with haematoxylin-eosin (H&E), Masson-trichrome (Masson), periodic acid-Schiff (PAS); the renal function determination; and the expression of Vimentin protein. Our findings indicate that the combined administration of CsA every day and furosemide every other day by gavage at 80 mg/kg and 60 mg/kg, respectively, for 28 days can be used to successfully establish a murine model of renal interstitial fibrosis. Immunohistochemistry was used to show the expression of renin, the initiator of renin angiotensin aldosterone system (RAAS), while Western blotting was used to show the expression of hypoxia-inducible factor-1α (HIF-1α), a sensitive indicator of hypoxia. The expression levels of renin and HIF-1α revealed that RAAS activation and hypoxia are important mechanisms of this the model. Altogether, the data suggest that our modified approach is also an effective, alternative way to establish this model.

Abstract
Carcinomas are phenotypically arrayed along an epithelial–mesenchymal transition (EMT) spectrum, a developmental program currently exploited to understand the acquisition of drug resistance through a re‐routing of growth factor signaling. This review collates the current approaches employed in developing therapeutics against cancer‐associated EMT, and provides an assessment of their respective strengths and drawbacks. We reflect on the close relationship between EMT and chemoresistance against current targeted therapeutics, with a special focus on the epigenetic mechanisms that link these processes. This prompts the hypothesis that carcinoma‐associated EMT shares a common epigenetic pathway to cellular plasticity as somatic cell reprogramming during tissue repair and regeneration. Indeed, their striking resemblance suggests that EMT in carcinoma is a pathological adaptation of an intrinsic program of cellular plasticity that is crucial to tissue homeostasis. We thus propose a revised approach that targets the epigenetic mechanisms underlying pathogenic EMT to arrest cellular plasticity regardless of upstream cancer‐driving mutations.

Abstract
PURPOSE Klotho deficiency is implicated in various kidney diseases, including renal fibrosis. The aim of this study was to investigate the effect of Klotho administration on epithelial-mesenchymal transition (EMT) and renal fibrosis induced by cyclosporine A (CsA) in rats. METHODS CsA-induced renal fibrosis was established by oral administration of CsA (30 mg/kg) to rats on a low-salt diet for 28 days. Klotho was administered to rats by intraperitoneal injection. Renal pathological changes were evaluated by hematoxylin and eosin and Masson's trichrome staining. The EMT response was assessed by measuring the level of TGF-β1, E-cadherin and α-SMA by immunohistochemistry and Western blot. RESULTS Administration of CsA for 28 days induced renal damage, decreased Klotho expression and activated the EMT response (demonstrated as increased TGF-β1 and α-SMA expression accompanied by decreased in E-cadherin expression). Treatment with Klotho significantly ameliorated pathological lesions of the kidney by modulating the expression of EMT-associated proteins in the kidney. CONCLUSIONS Klotho inhibits CsA-induced EMT and renal fibrosis in rats. Klotho may serve as a therapeutic agent to minimize CsA-induced renal fibrosis.

Abstract
Cyclosporine A (CsA) is widely used as an immunosuppressor in transplantation. Previous studies reported that CsA induces autophagy and that chronic treatment with CsA results in accumulation of autophagosomes and reduced autophagic clearance. Autophagy is a prosurvival process that promotes recovery from acute kidney injury by degrading misfolded proteins produced in the kidney. In the present study, we used TMBIM6-expressing HK-2, human kidney tubular cells (TMBIM6 cells) and Tmbim6 knockout (tmbim6(-/-)) mice. When exposed to CsA, the TMBIM6 cells maintained autophagy activity by preventing autophagosome accumulation. With regard to signaling, PRKKA/AMPK phosphorylation and mechanistic target of rapamycin (serine/threonine kinase) complex 1 (MTORC1) expression and its downstream target TFEB (transcription factor EB), a lysosome biogenesis factor, were regulated in the TMBIM6 cells. Lysosomal activity was highly increased or stably maintained in the presence of TMBIM6. In addition, treatment of tmbim6(-/-) mice with CsA resulted in increased autophagosome formation and decreased lysosome formation and activity. We also found that tmbim6(-/-) mice were susceptible to CsA-induced kidney injury. Taken together, these results indicate that TMBIM6 protects against CsA-induced nephrotoxicity both in vitro and in vivo by inducing autophagy and activating lysosomes.

Abstract
Chronic kidney disease is increasingly considered to be a worldwide public health problem and usually leads to renal fibrosis. In the present study, curcumin, a polyphenol pigment extracted from turmeric, was demonstrated to exert protective effects on renal fibrosis via the suppression of transforming growth factor‑β (TGF‑β) downstream signaling, such as plasminogen activator inhibitor‑1 (PAI‑1), α‑smooth muscle actin (α‑SMA) and collagen I (Col I) downregulation. The present findings demonstrate that curcumin exerted a protective effect on cyclosporine A‑induced renal fibrosis via a klotho (KL)‑dependent mechanism, which inhibits the TGF‑β signaling pathway. Further research indicated that curcumin induced KL expression in HK‑2 tubular epithelial cells by inhibiting CpG hypermethylation in the KL promoter, which mediates the loss of expression in cells. Methylation‑specific polymerase chain reaction (PCR) combined with bisulfite sequencing identified numerous key CpG sites, such as 249, 240 and 236, whose methylation statuses are important for KL expression. A PCR reporter assay was utilized to further confirm these findings. In addition, the effects of curcumin on the regulation of DNA methyltransferase 1 (Dnmt1) expression were evaluated, and the data suggest that curcumin inhibits Dnmt1 expression and restricts CpG hypermethylation. Thus, the current study reveals that curcumin attenuated renal fibrosis by suppressing CpG methylation in the KL promoter, thus inducing KL expression, which inhibited TGF‑β signaling, which may provide a novel therapeutic approach for the treatment of renal fibrosis.

Abstract
Acute tubular damage is a major cause of renal failure, especially at the early phase of kidney transplant when ischemia-reperfusion injury and cyclosporin A toxicity may coexist. The mechanisms of the latter are largely unknown. Using an mRNA microarray on microdissected tubules from a rat model of cyclosporin A toxicity to describe the related epithelial-specific transcriptional signature in vivo, we found that cyclosporin A induces pathways dependent on the transcription factor ATF4 and identified nuclear protein transcriptional regulator 1 (Nupr1), a stress response gene induced by ATF4, as the gene most strongly upregulated. Upon cyclosporin A treatment, Nupr1-deficient mice exhibited worse renal tubular lesions than wild-type mice. In primary cultures treated with cyclosporin A, renal tubular cells isolated from Nupr1-deficient mice exhibited more apoptosis and ATP depletion than cells from wild-type mice. Furthermore, cyclosporin A decreased protein synthesis and abolished proliferation in wild-type tubular cells, but only reduced proliferation in Nupr1-deficient cells. Compared with controls, mouse models of ischemia-reperfusion injury, urinary obstruction, and hypertension exhibited upregulated expression of renal NUPR1, and cyclosporin A induced Nupr1 expression in cultured human tubular epithelial cells. Finally, immunohistochemical analysis revealed strong expression of NUPR1 in the nuclei of renal proximal tubules of injured human kidney allografts, but not in those of stable allografts. Taken together, these results suggest that epithelial expression of NUPR1 has a protective role in response to injury after renal transplant and, presumably, in other forms of acute tubular damage.

Abstract
The tubular epithelium may be intrinsically involved in promoting kidney injury by junctional instability, epithelial-mesenchymal transition (EMT) and extracellular matrix remodelling. In this work, we investigated whether the pleiotropic and proinflammatory cytokine tumor necrosis factor-like weak inducer of apoptosis (TWEAK), could be able to disturb junctional protein expression and to induce EMT of tubular cells. In cultured murine proximal tubular cells TWEAK induced phenotypic changes that were accompanied by F-actin redistribution, loss of epithelial adherent (E-cadherin, Cadherin-16, β-catenin) and tight junction (ZO-1) proteins, and re-expression of the mesenchymal protein Vimentin. The transcriptional repressors Snail and HNF1β were also modulated by TWEAK. In a murine model of obstructive renal pathology, TWEAK expression correlated with the appearance of the mesenchymal marker αSMA in kidney tubular cells. Mechanistically, the epithelial changes induced by TWEAK, including loss of epithelial integrity and EMT, via Fn14 were TGF-β1 independent, but mediated by several intracellular signaling systems, including the canonical NF-κB, ERK activation and the vitamin D receptor modulation. These results highlight potential contributions of TWEAK-induced inflammatory mechanisms that could unveil new pathogenic effects of TWEAK starting tubulointerstitial damage and fibrosis.

Abstract
Antibody-mediated rejection (ABMR) is a leading cause of allograft loss. Treatment efficacy depends on accurate diagnosis at an early stage. However, sensitive and reliable markers of antibody-endothelium interaction during ABMR are not available for routine use. Using immunohistochemistry, we retrospectively studied the diagnostic value of three markers of endothelial-to-mesenchymal transition (EndMT), fascin1, vimentin, and heat shock protein 47, for ABMR in 53 renal transplant biopsy specimens, including 20 ABMR specimens, 24 cell-mediated rejection specimens, and nine normal grafts. We validated our results in an independent set of 74 unselected biopsy specimens. Endothelial cells of the peritubular capillaries in grafts with ABMR expressed fascin1, vimentin, and heat shock protein 47 strongly, whereas those from normal renal grafts did not. The level of EndMT marker expression was significantly associated with current ABMR criteria, including capillaritis, glomerulitis, peritubular capillary C4d deposition, and donor-specific antibodies. These markers allowed us to identify C4d-negative ABMR and to predict late occurrence of disease. EndMT markers were more specific than capillaritis for the diagnosis and prognosis of ABMR and predicted late (up to 4 years after biopsy) renal graft dysfunction and proteinuria. In the independent set of 74 renal graft biopsy specimens, the EndMT markers for the diagnosis of ABMR had a sensitivity of 100% and a specificity of 85%. Fascin1 expression in peritubular capillaries was also induced in a rat model of ABMR. In conclusion, EndMT markers are a sensitive and reliable diagnostic tool for detecting endothelial activation during ABMR and predicting late loss of allograft function.

Abstract
Markers of epithelial-mesenchymal transition (EMT) may identify patients at high risk of graft fibrogenesis who could benefit from early calcineurin inhibitor (CNI) withdrawal. In a randomized, open-label, 12-month trial, de novo kidney transplant patients received cyclosporine, enteric-coated mycophenolate sodium (EC-MPS) and steroids to month 3. Patients were stratified as EMT+ or EMT- based on month 3 biopsy, then randomized to start everolimus with half-dose EC-MPS (720 mg/day) and cyclosporine withdrawal (CNI-free) or continue cyclosporine with standard EC-MPS (CNI). The primary endpoint was progression of graft fibrosis (interstitial fibrosis/tubular atrophy [IF/TA] grade increase ≥1 between months 3-12) in EMT+ patients. 194 patients were randomized (96 CNI-free, 98 CNI); 153 (69 CNI-free, 84 CNI) were included in histological analyses. Fibrosis progression occurred in 46.2% (12/26) CNI-free EMT+ patients versus 51.6% (16/31) CNI EMT+ patients (p = 0.68). Biopsy-proven acute rejection (BPAR, including subclinical events) occurred in 25.0% and 5.1% of CNI-free and CNI patients, respectively (p < 0.001). In conclusion, early CNI withdrawal with everolimus initiation does not prevent interstitial fibrosis. Using this CNI-free protocol, in which everolimus exposure was relatively low and administered with half-dose EC-MPS, CNI-free patients were overwhelmingly under-immunosuppressed and experienced an increased risk of BPAR.

Abstract
Background While kidney injury is associated with re-expression of numerous Wnt ligands and receptors, molecular mechanisms which underlie regulation of distinct Wnt signaling pathways and ensuing biological consequences remain incompletely understood. Primary cilia are increasingly being recognized as cellular ‘antennae’ which sense and transduce signals from the microenvironment, particularly through Wnt signaling. Here, we explored the role of cilia as modulators of canonical and non-canonical Wnt signaling activities involving tubular epithelial cells in the injured kidney. Results We demonstrate that in the mouse model of unilateral ureter obstruction, progression of kidney injury correlates with increased expression of numerous Wnt ligands, and that increased expression of Wnt ligands corresponded with over-activation of canonical Wnt signaling. In contrast, non-canonical Wnt signaling dropped significantly during the course of kidney injury despite gradually increased expression of typical non-canonical and intermediate Wnt signaling ligands. We further demonstrate that in cultured tubular epithelial cells, cilia modulate balance between canonical and non-canonical signaling responses upon exposure to Wnt ligands. Conclusions We provide evidence that in the context of renal injury, primary cilia act as molecular switches between canonical and non-canonical Wnt signaling activity, possibly determining between regenerative and pro-fibrotic effects of Wnt re-expression in the injured kidney.

High prevalence of and potential mechanisms for chronic kidney disease in patients with acute intermittent porphyria. Kidney Int 2015; 88:386-95. [PMID: 25830761 DOI: 10.1038/ki.2015.97] [Citation(s) in RCA: 76] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2015] [Revised: 02/13/2015] [Accepted: 02/19/2015] [Indexed: 01/19/2023]
Abstract
Acute intermittent porphyria (AIP) is a genetic disorder of the synthesis of heme caused by a deficiency in hydroxymethylbilane synthase (HMBS), leading to the overproduction of the porphyrin precursors δ-aminolevulinic acid and porphobilinogen. The aim of this study is to describe the clinical and biological characteristics, the renal pathology, and the cellular mechanisms of chronic kidney disease associated with AIP. A total of 415 patients with HMBS deficiency followed up in the French Porphyria Center were enrolled in 2003 in a population-based study. A follow-up study was conducted in 2013, assessing patients for clinical, biological, and histological parameters. In vitro models were used to determine whether porphyrin precursors promote tubular and endothelial cytotoxicity. Chronic kidney disease occurred in up to 59% of the symptomatic AIP patients, with a decline in the glomerular filtration rate of ~1 ml/min per 1.73 m(2) annually. Proteinuria was absent in the vast majority of the cases. The renal pathology was a chronic tubulointerstitial nephropathy, associated with a fibrous intimal hyperplasia and focal cortical atrophy. Our experimental data provide evidence that porphyrin precursors promote endoplasmic reticulum stress, apoptosis, and epithelial phenotypic changes in proximal tubular cells. In conclusion, the diagnosis of chronic kidney disease associated with AIP should be considered in cases of chronic tubulointerstitial nephropathy and/or focal cortical atrophy with severe proliferative arteriosclerosis.

Abstract
Aim: The contribution of epithelial–mesenchymal transition (EMT) has been suggested in renal transplant recipients receiving calcineurin inhibitors and developing nephrotoxicity. Materials & methods: We assessed whether interindividual variability in tacrolimus pharmacokinetics is associated with the occurrence in tubular cells of two EMT markers (vimentin, β-catenin) detected at 3‐month in 140 allograft biopsies. We investigated whether genetic polymorphisms affecting CYP3A5 and ABCB1 influence EMT and kidney fibrosis. Results: In univariate analysis, the donor CYP3A5*1 allele was significantly associated with a lower vimentin expression. In multivariate analysis, grafts carrying ABCB1 3435T allele(s) developed significantly less EMT and less interstitial fibrosis. Conclusion: Donor SNPs significantly influence the epithelial program in the context of kidney transplantation, and the epithelial metabolism of tacrolimus is one key to understand graft fibrogenesis.

Progression of pulse pressure in kidney recipients durably exposed to CsA is a risk factor for epithelial phenotypic changes: an ancillary study of the CONCEPT trial. Transpl Int 2014; 27:344-52.

Abstract
In this ancillary study of the CONCEPT trial, we studied the role of CsA withdrawal at 3 months (3M) post-transplant on the intensity of epithelial phenotypic changes (EPC, an early marker for kidney fibrogenesis) on the 12 M surveillance biopsy. Although conversion from CsA to sirolimus (SRL) at 3M was reported to have improved mean graft function at 12 M, it did not reduce the score of EPC (1.73 ± 1.15 in the SRL group vs. 1.87 ± 1 in the CsA group, P = 0.61). Acute rejection, which had occurred twice more frequently in SRL-converted patients included here, was associated with 12 M EPC. Interestingly, we observed that the patients durably exposed to CsA and who developed 12 M EPC had a significant progression of blood pulse pressure (pp) from 1 to 6M post-transplantation (Δpp = +12.3 mmHg, P = 0.0035). Pulse pressure at 4, 6, and 9 M and pp progression from 1 to 6M were significantly associated with the development of EPC at 12 M in renal grafts. Logistic regression analysis revealed that a high 6M pp (≥ 60 mmHg) was an independent risk factor for 12 M EPC with an odds ratio of 2.25 per additional 10 mmHg pp (95%CI: 1.14-4.4, P = 0.02) after adjustment with recipient's and donor's age, acute rejection incidence and immunosuppressive regimen. A post hoc analysis of the data collected in the whole population CONCEPT study revealed that pp was significantly higher at 6 months in patients maintained on CsA and that at this time point pp correlated negatively with GFR at 1 year.

Abstract
Endothelin (ET) signaling provokes nephrotoxicity induced by the immunosuppressant drug cyclosporine A (CSA). We tested the hypotheses that (i): celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, counterbalances renal derangements caused by CSA in rats and (ii) the COX-2/endothelin ET(B) receptor signaling mediates the CSA-celecoxib interaction. Ten-day treatment with CSA (20 mg/kg/day) significantly increased biochemical indices of renal function (serum urea, creatinine), inflammation (interleukin-2, IL-2) and fibrosis (transforming growth factor-β₁, TGF-β₁). Histologically, CSA caused renal tubular atrophy along with interstitial fibrosis. These detrimental renal effects of CSA were largely reduced in rats treated concurrently with celecoxib (10 mg/kg/day). We also report that cortical glomerular and medullary tubular protein expressions of COX-2 and ET(B) receptors were reduced by CSA and restored to near-control values in rats treated simultaneously with celecoxib. The importance of ET(B) receptors in renal control and in the CSA-celecoxib interaction was further verified by the findings (i) most of the adverse biochemical, inflammatory, and histopathological profiles of CSA were replicated in rats treated with the endothelin ETB receptor antagonist BQ788 (0.1 mg/kg/day, 10 days), and (ii) the BQ788 effects, like those of CSA, were alleviated in rats treated concurrently with celecoxib. Together, the data suggest that the facilitation of the interplay between the TGF-β1/IL-2/COX-2 pathway and the endothelin ET(B) receptors constitutes the cellular mechanism by which celecoxib ameliorates the nephrotoxic manifestations of CSA in rats.

Abstract
Renal epithelial cells arise during embryogenesis by mesenchymal to epithelial transition (MET). In the context of renal diseases, these cells can switch back to a mesenchymal phenotype, in a process thus reminiscent of an epithelial-to-mesenchymal transition (EMT) in which we referred to as "Epithelial Phenotypic Changes" (EPC). The pathophysiological consequence of EPC is controversial: in particular, to what extent EPC contribute to the pool of disease-associated renal fibroblasts is very uncertain. However, there is strong evidence that EPC correlate with a poor renal outcome. EPC indeed reflect an exposure to a profibrotic environment, at an early and potentially reversible stage. Detecting EPC has potential therapeutic implications for patients prone to renal fibrosis, both as a marker of efficacy or more directly as a target. In opposition to the EMT occurring during embryogenesis, EMT in fibrosis as well as in cancer is an anarchic cellular process actually developing at the expense of the whole organ(ism).

Abstract
Fibrosis is a pathological scarring process that leads to destruction of organ architecture and impairment of organ function. Chronic loss of organ function in most organs, including bone marrow, heart, intestine, kidney, liver, lung, and skin, is associated with fibrosis, contributing to an estimated one third of natural deaths worldwide. Effective therapies to prevent or to even reverse existing fibrotic lesions are not yet available in any organ. There is hope that an understanding of common fibrosis pathways will lead to development of antifibrotic therapies that are effective in all of these tissues in the future. Here we review common and organ-specific pathways of tissue fibrosis.

Abstract
Some recently published works contest the epithelial origin of myofibroblasts, which are the major extracellular matrix producers. However, our previous studies showed that, in tubular cells, some phenotypic changes reminiscent of epithelial-to-mesenchymal transition constitute an interesting early marker that predicts the progression of fibrosis in renal grafts. We hypothesized that activated epithelial cells could directly contribute to fibrogenesis, although they remain within the tubules. Using immunohistochemistry, we studied the association between epithelial phenotypic changes (de novo expression of vimentin and intracellular translocation of β-catenin) and the production of profibrotic molecules (connective tissue growth factor, HSP47, and laminin), in tubular epithelial cells from 93 renal grafts biopsied of 77 patients. We observed the de novo production of connective tissue growth factor, HSP47, and laminin in the tubular epithelial cells displaying epithelial phenotypic changes. The score of vimentin was significantly correlated with those of connective tissue growth factor (r = 0.785, P < .0001), HSP47 (r = 0.887, P < .0001), and laminin (r = 0.836, P < .0001). The level of tubular expression of mesenchymal cell markers and profibrogenic molecules, but not graft histologic lesions according to Banff acute or chronic scores, was correlated with graft dysfunction and proteinuria at the time of biopsy (r = -0.611, P < .0001 for vimentin with estimated glomerular filtration rate) (r = 0.42, P = .0006 for vimentin with proteinuria). Our results demonstrate that the epithelial phenotypic switch is associated with an active fibrogenic process in tubular epithelial cells and with graft injury indicators. Perpetuation of this tissue injury-repair response may drive fibrogenesis in renal grafts. This "repair response" represents an interesting marker for renal graft surveillance.

Abstract
PURPOSE To investigate fibrotic lesions in renal tissues obtained from patients with large calculi, and to selectively evaluate the expression and clinical significance of Twist and E-cadherin in nephrolithiasis patients. METHODS We recruited 50 patients with kidney stone and 32 matched healthy controls. We determined plasma creatinine (Cr) and corrected Cr clearance (CCr). For the 50 patients, we detected daily urine protein excretion. At the end of percutaneous nephroscopic lithotomy, we performed puncture biopsy to acquire kidney tissue. We obtained normal control kidney tissues from non-nephrolithiasis patients who received a surgical biopsy during open surgery. We determined the expression of Twist and E-cadherin by immunohistochemical staining and scored it with clinical parameters. In addition, we analyzed the degree of expression of Twist and its correlation with long-term renal survival. RESULTS Overall, the renal function of patients significantly decreased, as indicated by Cr and reduced CCr compared with healthy controls. Activated Twist was strongly expressed in tubular epithelial cells from kidneys of nephrolithiasis patients, whereas we found little positive staining of Twist in normal kidneys. Meanwhile, the expression of E-cadherin was significantly suppressed in kidneys of nephrolithiasis patients. Twist expression was inversely correlated with E-cadherin expression; using multivariate analysis, data showed that the factors influencing renal survival in patients were CCr (relative ratio, 4.39; 95% confidence interval, 1.34-14.38; P = 0.013) and the extent of Twist expression (relative ratio, 3.45; 95% confidence interval, 1.10-10.68; P = 0.033). CONCLUSIONS Our data suggest that the possible novel EMT marker molecule Twist and Twist staining might be a valuable index predicting renal fibrosis progression in human nephrolithiasis.

Abstract
Epithelial-mesenchymal transition (EMT) plays a pivotal role in the pathogenesis of renal tubulointerstitial fibrosis. We previously demonstrated that aldosterone (Aldo)-induced EMT is dependent on mitochondrial-derived oxidative stress. This study investigated whether mitochondrial dysfunction (MtD) is involved in the pathogenesis of EMT and whether peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), a major regulator of oxidative metabolism and mitochondrial function, prevents EMT by improving MtD. Aldo decreased PGC-1α expression while increasing its acetylation and induced MtD, as evidenced by oxidative stress, mitochondrial membrane potential collapse, mitochondrial DNA damage, and mitochondrial complex activity reduction. Aldo time-dependently induced p66Shc phosphorylation and expression. Mineralocorticoid receptor antagonist eplerenone and p66Shc short interfering RNA prevented Aldo-induced MtD and EMT, as evidenced by downregulation of α-smooth muscle actin and upregulation of E-cadherin. Mitochondrial DNA depletion by ethidium bromide or mitochondrial transcription factor A inhibitory RNA (RNAi) induced MtD, further promoting EMT. RNAi-mediated suppression of PGC-1α induced MtD and EMT, whereas overexpression of PGC-1α prevented Aldo-induced MtD and inhibited EMT. Similarly, overexpression of silent mating type information regulation 2 homolog 1 (SIRT1), a gene upstream of PGC-1α, or the SIRT1 activator resveratrol restored Aldo-induced MtD and EMT by upregulating PGC-1α. These findings, which implicate a role for MtD in EMT and suggest that SIRT1 and PGC-1α coordinate to improve mitochondrial function and EMT, may guide us in therapeutic strategies for renal tubulointerstitial fibrosis.

Abstract
Hypoxia-inducible factor (HIF) is a transcription factor that regulates cellular hypoxic responses. Despite the therapeutic benefits of cyclosporine A (CsA) in organ transplantation, its clinical use is limited due to chronic nephropathy. We investigated whether HIF activation by cobalt could improve CsA-induced nephropathy, and investigated the related mechanism. In animal experiments, rats were kept on a 0.05% low-salt diet and administered CsA subcutaneously for 28 days (15 mg/kg/day). They also received cobalt (10 mg/kg/day) during the entire experimental period. The administration of cobalt significantly increased HIF-1α expression in the kidney. The increased expression of HIF-1α ameliorated CsA-induced afferent arteriolopathy and tubulointerstitial injury in the kidney. Cobalt significantly reduced the infiltration of macrophages/monocytes into the renal tubulointerstitium. In addition, HIF activation by cobalt reduced the number of CsA-induced apoptotic cells in the kidney. Subsequently, HK-2 human renal tubular epithelial cells were used for in vitro experiments. They were pre-treated with 150 µM of cobalt to activate HIF, and then exposed to 10 µM CsA. HIF activation by cobalt decreased the CsA-induced apoptosis in HK-2 cells, as judged by the decreases in the number of apoptotic cells, pro-apoptotic caspase-3 activity, and the expression level of cleaved caspase-3, together with the increase in the expression of anti-apoptotic bcl-2. Cobalt pretreatment also reduced the CsA-induced phosphorylation of NF-κB and the CsA-induced expression of vimentin and α-smooth muscle actin, suggesting the attenuation of inflammation and fibrosis. In conclusion, the activation of HIF by cobalt may ameliorate the CsA-induced nephropathy by inhibiting apoptosis, inflammation, and fibrosis.

Abstract
BACKGROUND A widely used immunosuppressant, cyclosporine A (CsA), conveys long-term nephrotoxicity in some patients. However, no specific marker is presently available. In both native and transplanted human kidneys, epithelial phenotypic changes (EPCs) suggestive of epithelial to mesenchymal transition (EMT) are expressed in various diseases and are prognostic with respect to progression of interstitial fibrosis. We hypothesized that CsA is able to trigger these EPCs in tubular cells in vivo. METHODS We studied the kinetics of the EMT markers β-catenin, snail, vimentin, collagen III, and HSP47 at the messenger RNA and protein levels in the kidneys from rats injected with 15 mg/kg/day of CsA or its vehicle. We investigated several therapeutic strategies available to block EMT in this model. RESULTS By 2 weeks, CsA had induced histological changes (tubular dilatation and vacuoles) and overexpression of EMT-related genes. This up-regulation of the EMT program was associated with tubular, not interstitial, overexpression of mesenchymal markers. Angiotensin II and endothelin receptor antagonists failed to prevent this CsA-induced EMT. Interestingly, CsA withdrawal led to the gradual regression of histological lesions and EMT, demonstrating that it not only prevents progression but also allows healing of renal injury. CONCLUSION Our study suggests that detecting EPC could help to identify ongoing renal CsA-induced toxicity at an early and reversible stage.
