Abstract
Doxorubicin (DOX) is an anti-neoplastic therapy, but its use is limited by its deleterious toxic effects including nephrotoxicity and cardiotoxicity. This work aimed at assessing the potential protective effect of Ceratonia siliqua methanol extract (CME) on DOX-induced nephrotoxicity in 5 groups of Wistar rats. Nephrotoxicity was induced experimentally by intraperitoneal (IP) injection of DOX (15 mg/kg). DOX increased serum creatinine, urea, sodium, and potassium levels. It elevated MDA levels in the renal tissue but decreased the concentration of GSH and the activity of GST, CAT, and SOD. Meanwhile, it decreased the level of immunomodulatory anti-inflammatory mediators: IL-10 and TGF-β, as well as the activity of MPO but increased the level of IL-6, TNF-α, and caspase-3 in the renal tissue. DOX has upregulated COX-2, caspase-9, and Bax gene expression and downregulated the Bcl-2 gene expression. Immunolabeling of renal tubular epithelium in DOX-intoxicated rats was moderate to strong against Bax, COX-2, and NF-kβ and weak against Bcl-2. Treatment with CME significantly restored the levels of kidney function parameters and the levels of oxidative stress markers. It stimulated the production of IL-10 and TGF-β and decreased the level of IL-6 and TNF-α. CME reverted the gene expression of COX-2, caspase-9, and Bax. Microscopically, CME alleviated the DOX-induced renal damage. Phytochemical analysis revealed the presence of 26 compounds in the CME. No signs of acute toxicity were recorded by CME up to 4000 mg/kg b. wt. orally into mice. Finally, CME could effectively alleviate the deleterious effects of DOX on the kidney. The safety of carob extract encourages its use in the preparation of valuable therapeutic agents.

The Role of V-Set Ig Domain-Containing 4 in Chronic Kidney Disease Models. Life (Basel) 2023; 13:life13020277. [PMID: 36836636 PMCID: PMC9965633 DOI: 10.3390/life13020277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 01/09/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
Abstract
V-set Ig domain-containing 4 (VSIG4) regulates an inflammatory response and is involved in various diseases. However, the role of VSIG4 in kidney diseases is still unclear. Here, we investigated VSIG4 expression in unilateral ureteral obstruction (UUO), doxorubicin-induced kidney injury mouse, and doxorubicin-induced podocyte injury models. The levels of urinary VSIG4 protein significantly increased in the UUO mice compared with that in the control. The expression of VSIG4 mRNA and protein in the UUO mice was significantly upregulated compared with that in the control. In the doxorubicin-induced kidney injury model, the levels of urinary albumin and VSIG4 for 24 h were significantly higher than those in the control mice. Notably, a significant correlation was observed between urinary levels of VSIG4 and albumin (r = 0.912, p < 0.001). Intrarenal VSIG4 mRNA and protein expression were also significantly higher in the doxorubicin-induced mice than in the control. In cultured podocytes, VSIG4 mRNA and protein expressions were significantly higher in the doxorubicin-treated groups (1.0 and 3.0 μg/mL) than in the controls at 12 and 24 h. In conclusion, VSIG4 expression was upregulated in the UUO and doxorubicin-induced kidney injury models. VSIG4 may be involved in pathogenesis and disease progression in chronic kidney disease models.

Abstract
Doxorubicin (DOX) treatment in cancer patients leads to nephrotoxicity. The nephroprotective effect of Berberine (BBR), a herbal ingredient, is well documented as antioxidant and activation of the Nrf2 signalling. This study aimed to investigate if Nrf2 is a major protective mechanism of BBR in DOX animal models. Rats were divided as (n = 6 each): Control, BBR (100 mg/kg, orally), DOX (15 mg/kg, orally), BBR + DOX, and BBR + DOX + brusatol (0.2 mg/kg, i.p./twice per week) (an Nrf2 inhibitor). DOX was given as a single dose (day 10), whereas BBR was administered for 3 weeks on a daily basis. BBR reduced tubular degeneration and improved renal markers in DOX-treated rats. It also reduced renal nuclear levels of NF-κB p65, total reactive oxygen species (ROS), lipid peroxides, interleukin-6 (IL-6), and tumour necrosis factor-α (TNF-α), as well as mRNA levels of Bax and cleaved caspase-3. However, BBR stimulated glutathione (GSH) and superoxide dismutase (SOD) levels, the transcription of Bcl2, and the mRNA, total cytoplasmic, and nuclear levels of Nrf2 with no effect on the cytoplasmic keap1 levels. All these effects disappeared by brusatol. In conclusion, BBR prevents DOX-induced renal damage by activating Nrf2.

Abstract
Cardiorenal syndrome (CRS) denotes the bidirectional interaction of chronic kidney disease and heart failure with an adverse prognosis but with a limited understanding of its pathogenesis. This study correlates biochemical blood markers, histopathological and immunohistochemistry features, and 2-deoxy-2-fluoro-D-glucose positron emission tomography (18F-FDG PET) metabolic data in low-dose doxorubicin-induced heart failure, cardiorenal syndrome, and renocardiac syndrome induced on Wistar male rats. To our knowledge, this is the first study that investigates the underlying mechanisms for CRS progression in rats using 18F-FDG PET. Clinical, metabolic cage monitoring, biochemistry, histopathology, and immunohistochemistry combined with PET/MRI (magnetic resonance imaging) data acquisition at distinct points in the disease progression were employed for this study in order to elucidate the available evidence of organ crosstalk between the heart and kidneys. In our CRS model, we found that chronic treatment with low-dose doxorubicin followed by acute 5/6 nephrectomy incurred the highest mortality among the study groups, while the model for renocardiac syndrome resulted in moderate-to-high mortality. 18F-FDG PET imaging evidenced the doxorubicin cardiotoxicity with vascular alterations, normal kidney development damage, and impaired function. Given the fact that standard clinical markers were insensitive to early renal injury, we believe that the decreasing values of the 18F-FDG PET-derived renal marker across the groups and, compared with their age-matched controls, along with the uniform distribution seen in healthy developing rats, could have a potential diagnostic and prognostic yield in cardiorenal syndrome.

Abstract
Doxorubicin (DOX) is used as an anticancer drug despite its many side effects. Thymoquinone (THQ) is a plant-derived substance that exhibits antioxidant and anti-inflammatory properties. We investigated the protective effects of THQ on DOX induced nephrotoxicity in rats. Rats were divided into five groups of eight: group 1, untreated control; group 2, olive oil group given olive oil intraperitoneally (i.p.) for 14 days; group 3, THQ group given 10 mg/kg THQ i.p. for 14 days; group 4, DOX group given a single dose of 15 mg/kg DOX i.p. on day 7 of experiment; group 5, DOX + THQ given 10 mg/kg THQ i.p. for 14 days and 15 mg/kg DOX i.p. on day 7. Kidney tissues were evaluated for histopathology. Caspase-3, IL-17, GRP78 and TNF-α immunostaining was used to determine the expression levels of these proteins among the groups. The TUNEL method was used to determine the apoptotic index. Total antioxidant status (TAS), total oxidant status (TOS), and TNF-α and TGF-β1 levels in kidney tissue were measured using ELISA assay. Histopathologic damage, caspase-3, IL-17, GRP78 and TNF-α immunoreactivity, TUNEL positive cells, TOS, TNF-α and TGF-β1 levels were increased in group 4 compared to group 1. The TAS of group 4 decreased compared to group 1. We found decreased caspase-3, IL-17, GRP78 and TNF-α expressions and TUNEL positive cells in group 5 compared to group 4. In rats given DOX, THQ reduced kidney damage by suppressing endoplasmic reticulum stress, inflammation and apoptosis pathways.

Abstract
The search for therapeutic agents that improve kidney function against doxorubicin-induced renal toxicity is important. Herein, the potential nephroprotective activity by Asparagus falcatus L. (AF, Asparagaceae) leaf extracts against doxorubicin-induced renal toxicity (5 mg/kg, ip) in Wistar rats (n = 6/group) after oral administration of hexane (55 mg/kg), ethyl acetate (35 mg/kg), butanol (75 mg/kg), and aqueous (200 mg/kg) extracts of AF for 28 consecutive days was investigated. It was noticed that the treatment with the selected extracts of AF significantly attenuated doxorubicin-induced elevations of serum creatinine, urea nitrogen, β2-microglobulin, cystatin C, and proteinuria in experimental rats. The histology showed attenuation of the features of acute tubular injury. Treatment regimens significantly reversed the doxorubicin-induced reduction in total antioxidant status, glutathione peroxidase, and glutathione reductase activity in renal tissue homogenates. A suppression in lipid peroxidation was noted with hexane, ethyl acetate, and butanol extracts of AF. Moreover, a reduction in the concentration of the pro-inflammatory mediator TNF-α (p < 0.05), and immunohistochemical expression of COX-2 were observed. The immunohistochemical expression of pro-apoptotic Bax protein was decreased and the anti-apoptotic BCL-2 was increased in renal tissues following the treatments. In conclusion, it was revealed that, hexane, ethyl acetate, butanol, and aqueous extracts of AF attenuate doxorubicin-induced renal toxicity in Wistar rats through antioxidant, anti-inflammatory, and anti-apoptotic pathways. The plant, AF could be recommended as a promising therapeutic agent to minimize renal toxicity induced by doxorubicin in cancer patients, however, subsequent clinical trials are warranted.

Abstract
AIMS Doxorubicin is a prominent anticancer agent. However, its organotoxic potential has restricted its clinical use. The current study was performed to investigate the protective effect of pirfenidone and vitamin D against doxorubicin-triggered nephrotoxicity. MATERIALS AND METHODS Female albino mice (5 mice per group) were inoculated with Ehrlish scites carcinoma (EAC) cells for induction of solid tumor and treated with pirfenidone 500 mg/kg orally (p.o.) or vitamin D 0.5 μg/kg intraperitonially (i.p.), either individually or combined with single doxorubicin (15 mg/kg; i.p.) dose. Additionally, 5 mice were served as a normal group. Treatment commenced 7 days after inoculation of Ehrlich ascites carcinoma cells and lasted for 14 days. KEY FINDINGS Pirfenidone and vitamin D enhanced the anti-tumor activity of doxorubicin, by decreasing tumor weight and volume. Doxorubicin increased kidney weights, creatinine, urea levels and collagen fibers deposition within renal tubules. Moreover, doxorubicin was associated with overexpression of nuclear factor-kappa B (NF-κB) and alpha-smooth muscle actin (α-SMA) as both parameters assessed by kidney immunohistochemistry. Furthermore, histological signs of large areas of interistital fibrosis and cellular infiltration were significant with sole doxorubicin treatment. Notably, doxorubicin elevated both MCP1 and TGFB1 gene expression in addition to increasing the protein expression of Smad3 and Jun N-terminal Kinase-1 (JNK1) while decreasing that of Smad7. Pirfenidone in combined with vitamin D abolished doxorubicin-evoked disturbances in the aforementioned parameters and blunted all histological alterations. SIGNIFICANCE Pirfenidone and vitamin D demonstrated a viable approach to suppress the nephrotoxicity initiated by doxorubicin through inhibiting the JNK1 and MCP-1 pathways.

Abstract
Doxorubicin (DOX) is a well-known anti-neoplastic agent that is widely employed to treat several types of malignancies. The current study was designed to investigate the renoprotective potential of berberine (BEB) on the doxorubicin (DOX)-induced nephrotoxicity and renal fibrosis. Rats were allocated into four groups; Negative Control, DOX nephrotoxic-induced group received a single dose of DOX (20 mg/kg, i.p.), BEB-group received (50 mg/kg, p.o.) for 14 days, and co-treatment group BEB + DOX where rats were pre-treated with BEB for 10 successive days, then received a single dose of DOX on the 11th day, followed by 4 days of receiving BEB. DOX resulted in nephrotoxicity manifested by significant increments in urea, creatinine, and kidney injury molecule (KIM-1), these biochemical findings were supported with the histopathological lesions in renal tissues. Moreover, DOX provoked oxidative stress through enhancing renal malondialdehyde (MDA) and hydrogen peroxide (H2O2) contents, and decreased renal catalase (CAT) activity. DOX triggered renal fibrosis represented by increased transforming growth factor beta-1 (TGF-β1) and elevated collagen deposition. DOX stimulated apoptosis and inflammation in renal tissues as confirmed by increased immunoexpression of caspase-3 and NF-κB, respectively. These effects were alleviated by BEB co-treatment. Co-treatment with BEB markedly prohibited DOX-induced oxidative damage, inflammation, apoptosis, and fibrosis in renal tissue. Histopathological and immunohistochemical investigations showed the nephroprotective potential of BEB on renal injury, which was consistent with the biochemical findings. Accordingly, it could be concluded that the nephroprotective potential of BEB against DOX-induced kidney injury and fibrosis might be mediated by the anti-oxidant, anti-inflammatory and anti-fibrosis activities.

Abstract
OBJECTIVES Chronic kidney disease (CKD) is a major public health problem associated with high mortality. The therapeutic effects of pachymic in CKD management and its underlying mechanisms have not been studied. Therefore, we aimed to investigate the possible inhibitory effect of PA on renal Wnt/β-catenin signalling in CKD. METHODS CKD was induced in rats by doxorubicin (DOX; 3.5 mg/kg i.p., twice weekly for 3 weeks). Rats were treated orally with PA (10 mg/kg/day), LOS (10 mg/kg/day) or their combination (PA + LOS) for 4 weeks starting after the last dose of DOX. KEY FINDINGS DOX-induced renal injury was characterized by high serum cystatin-C, and urine albumin/creatinine ratio, renal content of podocin and klotho were decreased. Tumour necrosis factor-α, interleukin-6, interleukin-1β, Wnt1, active β-catenin/total β-catenin ratio and fibronectin along with mRNA expression of RENIN, ACE and AT1 were increased in renal tissues. Treatment with either PA or LOS ameliorated all DOX-induced changes. The combined treatment was more effective in improving all changes than monotherapy. CONCLUSIONS These results suggest a new therapeutic benefit of PA in ameliorating CKD in rats through its up-regulatory effect on renal klotho thereby preventing Wnt/β-catenin reactivation and RAS gene expression. PA/LOS combination provided an additional inhibition of Wnt/β-catenin signalling and its downstream targets.

Abstract
Background and purpose: The clinical use of the chemotherapeutic drug, doxorubicin (DXR), is significantly limited by its extensive multi-organ toxicity. Dipeptidyl peptidase-4 (DPP4) is over-expressed in oxidative stress, inflammation and apoptosis. DPP4 inhibitors have proven pleiotropic effects. The study investigates the protective effects of some DDP4 inhibitors; namely, saxagliptin (SAX) and vildagliptin (VIL) against DXR-induced nephrotoxicity in rats. Experimental approach: Forty rats were divided into 4 groups. Group I served as normal control. Nephrotoxicity was induced in the remaining 3 groups by single-DXR injection (15 mg/kg, i.p.). Groups III and IV administered oral SAX (10 mg/kg) and VIL (10 mg/kg) for 2 weeks. Findings/Results: DXR-control rats showed deteriorated renal functions, elevated renal inflammatory parameters (tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), and inducible nitric oxide synthase (iNOS)), up-regulated nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome and significant tubulointerstitial injury manifested by elevated neutrophil gelatinase-associated lipocalin concentration and distorted renal histopathological pictures. Immunohistochemical studies showed increased iNOS and Bax positivity in renal tissues of DXR-control rats. Treatment with SAX and VIL significantly attenuated DXR-induced nephrotoxicity via alleviation of all the above-mentioned parameters when compared to DXR-control rats. Conclusion and implications: The study elucidated the possible mechanisms beyond DXR-induced nephrotoxicity to be through inflammation plus tubulointerstitial injury. DXR nephrotoxicity has been linked to TNF-α, IL-1β, and NLRP3 inflammasome up-regulation and iNOS expression. The protective role of SAX and VIL in mitigating the tubular injury and inflammatory effects of DXR on renal tissues has been tested and proved.

Abstract
This study investigated the nephroprotective role of acylated ghrelin (AG) against DOX-induced nephropathy and examined whether the protection involves silent information regulator 1 (SIRT1). Rats were divided into control, control + AG, DOX, DOX + AG, DOX + AG + [D-Lys3]-GHRP-6 (a ghrelin receptor antagonist), and DOX + AG + EX-527 (a sirt1 inhibitor). DOX was given over the first 2 weeks. AG (10 ng/kg) and both inhibitors were given as 3 doses/wk for 5 weeks. AG improved the structure and the function of the kidneys; down-regulated the renal expression of TGF-β1, collagen 1A1 and α-SMA; and inhibited the renal collagen deposition in the kidneys of DOX-treated rats. Concomitantly, it reduced the renal levels of ROS, MDA, TNF-α, and IL-6 and protein levels of cytochrome-c, TGF-β1, Smad3 and α-SMA in these rats. In both the control and DOX-treated rats, AG significantly increased the renal levels of SOD and GSH, decreased the expression of cleaved caspase-3 and Bax, increased the total levels and the nuclear activity of SIRT1 and reduced the deacetylation of p53, NF-κB and FOXO-31. All the effects were abolished by the concurrent administration of EX-527 and [D-Lys3]-GHRP-6. In conclusion, AG prevents DOX-induced nephropathy in SIRT1 and GSHRa1-dependent mechanism.

Abstract
Sunitinib (Sun), a tyrosine kinase inhibitor of vascular endothelial growth factor receptor, is the standard first‐line treatment against advanced clear cell renal cell carcinoma (RCC), but resistance to therapy is inevitable. Reactive oxygen species production is associated with sensitivity to chemotherapy, but the underlying mechanisms are not completely understood. Here, we investigated the mechanisms contributing to Sun resistance using the RCC cell lines ACHN and 786‐O. We report that Sun‐resistant cells exhibited reduced apoptosis, increased cell viability, increased reactive oxygen species production and disrupted mitochondrial function. Furthermore, chronic Sun treatment resulted in an up‐regulation of Sirt5/isocitrate dehydrogenase 2 (IDH2) expression levels. Knockdown of Sirt5/IDH2 impaired mitochondrial function and partially attenuated Sun resistance. Finally, up‐regulation of Sirt5 enhanced the expression of IDH2 via modulation of succinylation at K413 and promoted protein stability. In conclusion, dysregulation of Sirt5/IDH2 partially contributes to Sun resistance in RCC cells by affecting antioxidant capacity.

Abstract
The global burden of chronic kidney disease (CKD) intertwined with cardiovascular disease has become a major health problem. Oxidative stress (OS) plays an important role in the pathophysiology of CKD. The nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant responsive element (ARE) antioxidant system plays a critical role in kidney protection by regulating antioxidants during OS. Heme oxygenase-1 (HO-1), one of the targets of Nrf2-ARE, plays an important role in regulating OS and is protective in a variety of human and animal models of kidney disease. Thus, activation of Nrf2-HO-1 signaling may offer a potential approach to the design of novel therapeutic agents for kidney diseases. In this review, we have discussed the association between OS and the pathogenesis of CKD. We propose Nrf2-HO-1 signaling-mediated cell survival systems be explored as pharmacological targets for the treatment of CKD and have reviewed the literature on the beneficial effects of small molecule natural products that may provide protection against CKD.

[PMID: 33482150 DOI: 10.1016/j.bcp.2021.114426] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 01/14/2021] [Accepted: 01/15/2021] [Indexed: 12/16/2022]
Abstract
Infliximab (IFX), a chimeric monoclonal antibody against tumor necrosis factor-α (TNF-α), is widely used to treat autoimmune diseases and chronic diseases associated with inflammation. TNF-α was reported to inhibit klotho, reactivate β-catenin and cause tubular cell injury in vitro. Whether the inhibition of TNF-α can regulate Wnt/β-catenin pathway via klotho in CKD in vivo is not studied yet. We aimed to investigate the impact of IFX on Wnt/β-catenin pathway in doxorubicin (DOX)-induced nephropathy. Doxorubicin (3.5 mg/kg; i.p., twice weekly for 3 weeks) increased serum cystatin-C, urine albumin/creatinine ratio (UACR), but depleted renal podocin. It markedly increased renal contents of TNF-α, interleukin-6 (IL-6), interleukin-1β (IL1β). DOX decreased the renal expression of klotho which in turn increased Wnt1, active β-catenin/total β-catenin ratio in renal tissue. Significant increase in renal gene expression of RENIN, ACE, and AT1 was observed. Moreover, renal fibronectin and collagen deposition increased in renal tissue. Treatment with either IFX (5 mg/kg, once; i.p.), losartan (LOS, 10 mg/kg/day, orally) or their combination significantly improved renal function, inhibited inflammatory cytokines and fibrosis. Renal TNF-α was negatively correlated with renal klotho. On the hand, it was positively correlated with renal Wnt1 and active β-catenin/total β-catenin ratio. The combined IFX and LOS treatment was the most effective in improving all studied parameters. In conclusion, this study proved, for the first time, the inhibitory effect of IFX on renal Wnt/β-catenin signaling in DOX-induced nephropathy in vivo by up-regulating renal klotho. Therefore, these results suggest a new role for IFX in chronic kidney disease via targeting renal Wnt/β-catenin/renin angiotensin axis.

Abstract
This study examines the protective effects of omega-3 fatty acids (OMG), a frequently used nutritional therapy in cancer patients, against doxorubicin (DOX)-induced acute cardiorenal toxicity in rats, and evaluates the cytotoxic activity of DOX when used with OMG against breast cancer cell line. Five groups of rats were treated for 4 consecutive weeks with vehicle (groups I & II), or OMG (25, 50 or 100 mg/kg/day, po; groups III, IV & V, respectively). After twenty-four hours, the last four groups were injected with DOX (200 mg/kg, ip). In DOX-treated rats, the altered ECG, serum cardiac and renal function biomarkers, and histopathological features indicated the induction of cardiorenal toxicity. Increased oxidative and apoptotic markers in both organs was observed, with elevated renal contents of NADPH-oxidase-4 (Nox4) and renin. OMG pretreatment improved those DOX-induced impairments in a dose-dependent manner, and showed antioxidant and antiapoptotic effects with regulation of renal Nox4 expression. The in-vitro study showed preservation of the cytotoxic activity of DOX on MCF7 cell line in the presence of OMG. The data suggests OMG for protection against acute DOX-induced cardiorenal damage without affecting the latter antitumor activity. It proposes regulation of oxidative stress, Nox4 activity and apoptosis as contributing protective mechanisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abelmoschus moschatus Medik. (family: Malvaceae), Asparagus falcatus (family: Asparagaceae) and Barleria prionitis Linn. (family: Acanthaceae) have been used in the treatment of kidney diseases in Sri Lankan traditional medicine. Besides the traditional use, scientific scrutinization of safe therapeutic use of these medicinal plants in the management of kidney diseases has not been reported to date. AIM OF THE STUDY The three selected doses of the aqueous extracts of the selected medicinal plants were studied for their protective effects against adriamycin (ADR) induced nephrotoxicity in Wistar rats. MATERIALS AND METHODS Chemically standardized plant materials were used in the study. The nephroprotective activity of the lyophilized powder of the aqueous refluxed (4hr) leaf extracts of A. moschatus, A. falcatus and the whole plant extract of B. prionitis was investigated in adriamycin (20 mg/kg, ip) induced nephrotoxicity in Wistar rats (n = 6/group). The treatment regimens were initiated 24 h after the induction of nephrotoxicity and continued daily as a single dose for three consecutive days at three selected doses (200, 400 and 600 mg/kg). Fosinopril sodium (0.09 mg/kg) was used as the standard drug. Nephroprotective activity was assessed by estimating the selected biochemical parameters and by the assessment of histopathology on H and E stained sections of the kidney. RESULTS The plant extracts at the three selected doses significantly attenuated the elevations in serum creatinine, blood urea nitrogen and the loss of urine total protein in a dose related manner in ADR induced nephrotoxic rats (p < 0.001). The serum concentration of albumin and total protein increased significantly (p < 0.001). Histopathological findings corroborated the biochemical evidence of nephroprotective activity. The aqueous extracts of the three selected medicinal plants exerted a relatively high antioxidant activity in vitro. CONCLUSIONS Evaluation of the protective effects based on biochemical parameters and histopathology assessment revealed that the aqueous leaf extracts of A. moschatus, A. falcatus and the whole plant extract of B. prionitis possess significant nephroprotective activity against ADR induced acute nephrotoxicity. The secondary metabolites present in the plant extracts may attribute to the total antioxidant activities of the selected medicinal plant extracts thereby exerting protective effects against nephrotoxicity in Wistar rats.

Abstract
Renal inflammation is a final common pathway of chronic kidney disease (CKD), and its progression can be used to effectively gauge the degree of renal dysfunction. Inflammatory mechanisms contribute to glomerulosclerosis and tubulointerstitial fibrosis, which are hallmarks of CKD leading to end-stage renal disease. Receptor-interacting protein kinase 2 (RIP2) is largely committed to nucleotide-binding oligomerization domain signaling as a direct effector and transmits nuclear factor-κB (NF-κB)-mediated proinflammatory cytokine production. In the present study, we hypothesized that if inflammation via RIP2 and NF-κB signaling plays an important role in renal failure, then the anti-inflammatory effect of RIP2 inhibitors should be effective in improving CKD. To determine its pharmacologic potency, we investigated the renoprotective properties of the novel RIP2 inhibitor AS3334034 [7-methoxy-6-(2-methylpropane-2-sulfonyl)-N-(4-methyl-1H-pyrazol-3-yl)quinolin-4-amine] in uninephrectomized adriamycin-induced CKD rats. Six weeks' repeated administration of AS3334034 (10 mg/kg, once daily) significantly reduced urinary protein excretion and prevented the development of glomerulosclerosis and tubulointerstitial fibrosis. In addition, AS3334034 showed beneficial effects on renal function, as demonstrated by a decrease in levels of plasma creatinine and blood urea nitrogen and attenuation of a decline in creatinine clearance. Furthermore, AS3334034 significantly attenuated inflammation, renal apoptosis, and glomerular podocyte loss. These results suggest that the RIP2 inhibitor AS3334034 suppresses the progression of chronic renal failure via an anti-inflammatory effect and is therefore potentially useful in treating patients with CKD. SIGNIFICANCE STATEMENT: The receptor-interacting protein kinase 2 (RIP2) inhibitor AS3334034 suppresses the progression of chronic renal failure via an anti-inflammatory effect, suggesting that the nucleotide-binding oligomerization domain-RIP2 axis might play a crucial role in the pathogenesis of inflammatory kidney diseases. AS3334034 is expected to be potentially useful in the treatment of patients with chronic kidney disease.

Abstract
Aim: This paper aims to investigate a doxorubicin (DOX) chronic kidney disease rat model using magnetic nanoparticles (MNPs) associated with the alternate current biosusceptometry (ACB) to analyze its different perfusion profiles in both healthy and DOX-injured kidneys. Materials & methods: We used the ACB to detect the MNP kidney perfusion in vivo. Furthermore, we performed biochemical and histological analyses, which sustained results obtained from the ACB system. We also studied the MNP biodistribution. Results: We found that DOX kidney injury alters the MNPs' kidney perfusion. These changes became more intense as the disease progressed. Moreover, DOX has an important effect on MNP biodistribution as the disease evolved. Conclusion: This study provides new applications of MNPs in nephrology, instrumentation, pharmacology, physiology and nanomedicine.

Abstract
Mesenchymal stem cells (MSCs) ameliorate the renal injury in Adriamycin (ADR)-induced nephropathy, but the mechanisms underlying their efficacy remain incompletely understood. In this study, we demonstrated that MSCs increased the survival, recovered body weight loss, and decreased proteinuria and serum creatinine levels in ADR-treated mice. MSCs also prevented podocyte damage and renal fibrosis by decreasing the expression of fibronectin, collagen 1α1, and α-smooth muscle actin. From a mechanistic perspective, MSCs inhibited renal inflammation by lowering the expression of CCL4, CCL7, CCL19, IFN-α/β, TGF-β, TNF-α, and chitinase 3-like 1. In summary, our data demonstrate that MSCs improve renal functions by inhibiting renal inflammation in ADR-induced nephropathy.

[PMID: 31546603 PMCID: PMC6801943 DOI: 10.3390/ijms20194680] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2019] [Revised: 09/14/2019] [Accepted: 09/17/2019] [Indexed: 12/13/2022] Open
Abstract
Hyperuricemia has been recognized as a risk factor for insulin resistance as well as one of the factors leading to diabetic kidney disease (DKD). Since DKD is the most common cause of end-stage renal disease, we investigated whether febuxostat, a xanthine oxidase (XO) inhibitor, exerts a protective effect against the development of DKD. We used KK-Ay mice, an established obese diabetic rodent model. Eight-week-old KK-Ay mice were provided drinking water with or without febuxostat (15 μg/mL) for 12 weeks and then subjected to experimentation. Urine albumin secretion and degrees of glomerular injury judged by microscopic observations were markedly higher in KK-Ay than in control lean mice. These elevations were significantly normalized by febuxostat treatment. On the other hand, body weights and high serum glucose concentrations and glycated albumin levels of KK-Ay mice were not affected by febuxostat treatment, despite glucose tolerance and insulin tolerance tests having revealed febuxostat significantly improved insulin sensitivity and glucose tolerance. Interestingly, the IL-1β, IL-6, MCP-1, and ICAM-1 mRNA levels, which were increased in KK-Ay mouse kidneys as compared with normal controls, were suppressed by febuxostat administration. These data indicate a protective effect of XO inhibitors against the development of DKD, and the underlying mechanism likely involves inflammation suppression which is independent of hyperglycemia amelioration.

Abstract
We investigated the potential nephroprotective effects of misoprostol (MP) on doxorubicin (DOX) induced renal injury using histologic and biochemical assessment of rat kidneys. We used 21 male rats divided into three groups: group 1, control; group 2, DOX; group 3, DOX + MP. The control group was given 0.5 ml 0.9% NaCl and 1 ml 0.9% NaCl orally for 6 days. DOX was administered as a single dose of 20 mg/kg on day 3. MP was administered orally for 6 days. We found that treatment with MP decreased serum creatinine and blood urea nitrogen levels significantly. DOX increased the malondialdehyde level and decreased catalase, superoxide dismutase activities and glutathione level. These alterations were prevented in renal tissues by MP. MP also decreased NADPH oxidase-4 and caspase-3 levels. In the DOX + MP group, oxidative stress was decreased, antioxidant activity was increased and histopathological changes were reduced compared to the DOX group. Renal injury caused by DOX was attenuated by MP treatment owing to the antioxidative and anti-apoptotic effects of MP.

Abstract
The acute kidney injury(AKI) caused by nephrotoxic drugs contributes to inflammation and oxidative injury in podocytes. Wedelolactone (WED), a natural compound, is found with activities as anti-inflammation, anti-oxidative, anti-free radical,and etc. In this present study, MPC-5 cells were exposed to the nephrotoxic drugs doxorubicin (DOX). The results showed that WED significantly increased the SOD activity, CAT and GSH-Px levels, while significantly decreased the MDA content and ROS levels in DOX-induced MPC-5 cells. WED could also significantly decrease the levels of cytokines IL-6, MCP-1, TNF-α, and TGF-β1. Additionally, the activation and phosphorylation of IκKα, IκBα and NF-κB p65 was inhibited by WED. The co-treatment of PDTC (NF-κB inhibitor) and WED significantly reduced NF-κB p65 phosphorylation. These findings suggested that WED alleviated inflammation and oxidative stress of doxorubicin-induced MPC-5 cells through IκK/IκB/NF-κB signaling pathway.

Abstract
Doxorubicin (DOX) is a cytostatic antibiotic from the class of anthracyclines widely used in chemotherapeutic cancer treatments. Despite the efficiency against several types of cancer, the use of DOX remains limited due to the side effects, especially cardiotoxicity. Among the DOX administration strategies, there are the "classic players" such as nanoparticles and polymers, which are capable of DOX delivery directly to interesting neoplastic regions. On the other hand, the "new players" such as phytochemicals and probiotics emerged with the proposal to react with DOX free radicals, reducing the oxidative stress, inflammatory and apoptotic process. Thus, this review aims to report the studies involving these classics and new players along the years that focus on improved administration and reduction of DOX-induced cardiotoxicity.

Sexual dimorphism of acute doxorubicin-induced nephrotoxicity in C57Bl/6 mice. PLoS One 2019; 14:e0212486.

Abstract
Doxorubicin (DOX) is a chemotherapeutic agent that has been reported to cause nephrotoxicity in rodent models and to a lesser degree in cancer patients. Female rodents have been shown to be protected against several features of DOX-induced nephrotoxicity. Nevertheless, the underlying mechanisms of this sexual dimorphism are not fully elucidated. Therefore, in the current study, we investigated the sex and time-dependent changes in pathological lesions as well as apoptotic and fibrotic markers in response to acute DOX-induced nephrotoxicity. We also determined the effect of acute DOX treatment on the renal expression of the sexually dimorphic enzyme, soluble epoxide hydrolase (sEH), since inhibition of sEH has been shown to protect against DOX-induced nephrotoxicity. Acute DOX-induced nephrotoxicity was induced by a single intra-peritoneal injection of 20 mg/kg DOX to male and female adult C57Bl/6 mice. The kidneys were isolated 1, 3 and 6 days after DOX administration. Histopathology assessment, gene expression of the apoptotic marker, BAX, protein expression of the fibrotic marker, transforming growth factor-β (TGF-β), and gene and protein expression of sEH were assessed. DOX administration caused more severe pathological lesions as well as higher induction of the apoptotic and fibrotic markers in kidneys of male than in female mice. Intriguingly, DOX inhibited sEH protein expression in kidneys of male mice sacrificed at 3 and 6 days following administration, suggesting that induction of sEH is not necessary for acute DOX-induced nephrotoxicity. However, DOX-induced inhibition of renal sEH in male mice may protect the kidney from further DOX-induced injury in a negative feedback mechanism. We also observed lower constitutive expressions of TGF-β and sEH in the kidney of female mice which may contribute, at least in part, to sexual dimorphism of DOX-induced nephrotoxicity.

Abstract
Recent clinical studies have demonstrated the protective effect of xanthine oxidase (XO) inhibitors against chronic kidney diseases, although the underlying molecular mechanisms remain unclear. However, to date, neither clinical nor basic research has been carried out to elucidate the efficacy of XO inhibitor administration for IgA nephropathy. We thus investigated whether febuxostat, an XO inhibitor, exerts a protective effect against the development of IgA nephropathy, using gddY mice as an IgA nephropathy rodent model. Eight-week-old gddY mice were provided drinking water with (15 μg/mL) or without febuxostat for nine weeks and then subjected to experimentation. Elevated serum creatinine and degrees of glomerular sclerosis and fibrosis, judged by microscopic observations, were significantly milder in the febuxostat-treated than in the untreated gddY mice, while body weights and serum IgA concentrations did not differ between the two groups. In addition, elevated mRNA levels of inflammatory cytokines such as TNFα, MCP-1, IL-1β, and IL-6, collagen isoforms and chemokines in the gddY mouse kidneys were clearly normalized by the administration of febuxostat. These data suggest a protective effect of XO inhibitors against the development of IgA nephropathy, possibly via suppression of inflammation and its resultant fibrotic changes, without affecting the serum IgA concentration.

Abstract
Doxorubicin (DX) is a chemotherapeutic drug that is used in clinical practice that promotes deleterious side effects in non-tumor tissues such as adipose tissue. We showed that DX leads to extensive damage in adipose tissue via a disruption in 5′-adenosine monophosphate-activated protein kinase (AMPK) and PPAR-gamma signaling. Thus, we investigated whether co-treatment with the biguanide drug metformin (MET) could prevent the side effects of DX through the activation of AMPK in adipose tissue. The goal of the present study was to verify the effects of DX and adjuvant MET treatment in subcutaneous adipose tissue (SAT) and to determine whether MET could protect against chemotherapy-induced side effects. C57/BL6 mice received DX hydrochloride (2.5 mg/kg) intraperitoneally 2 times per week for 2 weeks (DX), concomitantly or not, with MET administration (300 mg/kg oral daily) (DX + MET). The control group (CTRL) was pair-fed according to the food consumption of the DX group. After euthanasia, adipose tissue fat pads were collected, and SAT was extracted so that adipocytes could be isolated. Glucose uptake was then measured, and histological, gene, and protein analyses were performed. One-way analysis of variance was also performed, and significance was set to 5%. DX reduced retroperitoneal fat mass and epididymal pads and decreased glycemia. In cultured primary subcutaneous adipocytes, mice in the DX group had lower glucose uptake when stimulated with insulin compared with mice in the CTRL group. Adipocytes in the DX group exhibited a reduced area, perimeter, and diameter; decreased adiponectin secretion; and decreased fatty acid synthase gene expression. SAT from MET-treated mice also showed a reduction in collagen deposition. Treatment with MET prevented fibrosis and restored glucose uptake in SAT after insulin stimulation, yet the drug was unable to prevent other side effects of DX such as tissue loss and inflammatory response.

Abstract
Knowing the therapeutic effects of regular physical exercise on kidney toxicity induced by a single dose of doxorubicin (DOX) in animal models, the aim of this study is to verify the effectiveness of regular voluntary running on kidney histology after a prolonged DOX administration, mimicking a chemotherapy protocol. Thirty-four male Wistar rats were randomly divided into two clusters: DOX (n = 17) and SSS (sterile saline solution, n = 17), receiving a weekly intraperitoneal injection of DOX (2 mg/kg) or vehicle for 7 weeks, respectively. Two weeks after the last injection, five animals from each cluster (SSSG, n = 5; DOXG, n = 5) were euthanized, while the remaining ones were divided into sedentary (DOXsed, n = 6; SSSsed, n = 6) and active subgroups (DOXact, n = 6; SSSact, n = 6). Active animals were placed individually in cages with a running wheel for regular voluntary activity. After 2 months, the animals were euthanized and kidneys were histologically examined. Compared to SSSG, kidneys from DOXG revealed higher levels of damage, more collagen content and thickening of Bowman's capsule (p < .05). The levels of damage and thickness of Bowman's capsule increased in DOXsed as compared to DOXG (p < .05). Compared to DOXsed, the DOXact presented an overall improvement in kidney structure (p < .05), with a decrease in collagen content and of the thickness of Bowman's capsule. The results allow concluding that regular voluntary running attenuate the long-term harmful effects on kidney structure induced by a prolonged DOX treatment. These results, supporting the potential benefit of physical activity in patients under DOX treatment, need to be tested in humans.

Abstract
OBJECTIVE The aim of the present study was to evaluate the possible protective effect of Plantago major (P. major) extract against doxorubicin (DXR)-induced renal inflammation in rats. MATERIALS AND METHODS 80 male albino rats were randomly divided into 8 groups as follows: control, DXR, Ext (extract) 600, Ext1200, dexamethasone+DXR, vitamin E+DXR, Ext600+DXR, and Ext1200+DXR. Duration of the study was 35 days and DXR was intravenously injected on the 7th day of the experiment. Tumor necrosis factor-alpha (TNF-α) production and monocyte chemoattractant protein-1 (MCP-1) expression levels were assessed in the left kidney. Serum creatinine concentration and osmolarity were determined on the 1st, 14th, 21st, 28th and 35th days of the experiment. RESULTS DXR caused a significant increase in renal expression of MCP-1 and TNF-α production compared to control animals. Administration of dexamethasone, vitamin E and P. major extract significantly improved the expression of these inflammatory mediators compared to DXR group. Compared to day 1 in DXR group, serum osmolarity showed a significant increase on days 21, 28 and 35. Also, on these days, serum osmolarity in DXR group was significantly higher than that on the same days in control group. In Vit E+DXR and Ext 1200+DXR groups, there was no significant changes in serum osmolarity among different days of the study. However, in these groups, serum osmolarity on days 21, 28 and 35 showed a significant decrease compared to the same days in DXR group. CONCLUSION Present results suggest that hydroethanolic extract of P. major protected renal tissue against DXR-induced renal inflammation.

Abstract
SIGNIFICANCE The extracellular matrix (ECM) is an essential modulator of cell behavior that influences tissue organization. It has a strong relevance in homeostasis and translational implications for human disease. In addition to ECM structural proteins, matricellular proteins are important regulators of the ECM that are involved in a myriad of different pathologies. Recent Advances: Biochemical studies, animal models, and study of human diseases have contributed to the knowledge of molecular mechanisms involved in remodeling of the ECM, both in homeostasis and disease. Some of them might help in the development of new therapeutic strategies. This review aims to review what is known about some of the most studied matricellular proteins and their regulation by hypoxia and redox signaling, as well as the pathological implications of such regulation. CRITICAL ISSUES Matricellular proteins have complex regulatory functions and are modulated by hypoxia and redox signaling through diverse mechanisms, in some cases with controversial effects that can be cell or tissue specific and context dependent. Therefore, a better understanding of these regulatory processes would be of great benefit and will open new avenues of considerable therapeutic potential. FUTURE DIRECTIONS Characterizing the specific molecular mechanisms that modulate matricellular proteins in pathological processes that involve hypoxia and redox signaling warrants additional consideration to harness the potential therapeutic value of these regulatory proteins.

Abstract
Obesity-related renal diseases have been a worldwide issue. Effective strategy that prevents high fat-diet induced renal damage is of great significance. Resveratrol, a natural plant polyphenol, is famous for its antioxidant activity, cardioprotective effects and anticancer properties. However whether resveratrol can play a role in the treatment of renal diseases is unknown. In this study, we added resveratrol in normal glucose or high glucose medium and provide evidences that resveratrol protects against high-glucose triggered oxidative stress and cell senescence. Moreover, mice were fed with standard diet, standard diet plus resveratrol, high-fat diet or high-fat diet plus resveratrol for 3 months, and results show that resveratrol treatment prevents high-fat diet induced renal pathological damage by activating SIRT1, a key member in the mammalian sirtuin family that response to calorie restriction life-extension method. This research confirms the potential role of resveratrol in the treatment of renal diseases and may provide an effective and convenient method to mimic the beneficial effects of calorie restriction.

Abstract
Chronic alcohol consumption is a well-known risk factor for tissue injury. The link between alcohol use disorder (AUD) and kidney injury is intriguing but controversial, and the molecular mechanisms by which alcohol may damage the kidneys are poorly understood. Epidemiological studies attempting to link AUD and kidney disease are, to date, inconclusive, and there is little experimental evidence directly linking alcohol consumption to kidney injury. However, studies conducted primarily in other organs and tissues suggest several possible mechanisms by which alcohol may promote kidney dysfunction. One possible mechanism is oxidative stress resulting from increased production of reactive oxygen species, which leads to an excessive amount of free radicals, which in turn trigger tissue injury and increase inflammation. In addition, AUD's effect on other major organs (liver, heart, intestines, and skeletal muscle) appears to promote unfavorable pathological processes that are harmful to the kidneys. Notably, these mechanisms have not yet been validated experimentally in the kidney. Additional research is needed to clarify if alcohol does indeed promote kidney injury and the mechanisms by which alcohol-induced kidney injury may occur.

Abstract
The concentration of adenosine in the normal kidney increases markedly during renal hypoxia, ischemia, and inflammation. A recent study reported that an A3 adenosine receptor (A3AR) antagonist attenuated the progression of renal fibrosis. The adriamycin (ADX)-induced nephropathy model induces podocyte injury, which results in severe proteinuria and progressive glomerulosclerosis. In this study, we investigated the preventive effect of a highly selective A3AR antagonist (LJ1888) in ADX-induced nephropathy. Three groups of six-week-old Balb/c mice were treated with ADX (11 mg/kg) for four weeks and LJ1888 (10 mg/kg) for two weeks as following: 1) control; 2) ADX; and 3) ADX + LJ1888. ADX treatment decreased body weight without a change in water and food intake, but this was ameliorated by LJ1888 treatment. Interestingly, LJ1888 lowered plasma creatinine level, proteinuria, and albuminuria, which had increased during ADX treatment. Furthermore, LJ1888 inhibited urinary nephrin excretion as a podocyte injury marker, and urine 8-isoprostane and kidney lipid peroxide concentration, which are markers of oxidative stress, increased after injection of ADX. ADX also induced the activation of proinflammatory and profibrotic molecules such as TGF-β1, MCP-1, PAI-1, type IV collagen, NF-κB, NOX4, TLR4, TNFα, IL-1β, and IFN-γ, but they were remarkably suppressed after LJ1888 treatment. In conclusion, our results suggest that LJ1888 has a renoprotective effect in ADX-induced nephropathy, which might be associated with podocyte injury through oxidative stress. Therefore, LJ1888, a selective A3AR antagonist, could be considered as a potential therapeutic agent in renal glomerular diseases which include podocyte injury and proteinuria.

Abstract
Doxorubicin (DOXO) induces significant, but transient, increases in apoptosis in the stem cell zone of the jejunum, followed by mucosal damage involving a decrease in crypt proliferation, crypt number, and villus height. The gastrointestinal tract is home to a vast population of commensal bacteria and numerous studies have demonstrated a symbiotic relationship between intestinal bacteria and intestinal epithelial cells (IEC) in maintaining homeostatic functions of the intestine. However, whether enteric bacteria play a role in DOXO-induced damage is not well understood. We hypothesized that enteric bacteria are necessary for induction of apoptosis and damage associated with DOXO treatment. Conventionally raised (CONV) and germ free (GF) mice were given a single injection of DOXO, and intestinal tissue was collected at 6, 72, and 120 h after treatment and from no treatment (0 h) controls. Histology and morphometric analyses quantified apoptosis, mitosis, crypt depth, villus height, and crypt density. Immunostaining for muc2 and lysozyme evaluated Paneth cells, goblet cells or dual stained intermediate cells. DOXO administration induced significant increases in apoptosis in jejunal epithelium regardless of the presence of enteric bacteria; however, the resulting injury, as demonstrated by statistically significant changes in crypt depth, crypt number, and proliferative cell number, was dependent upon the presence of enteric bacteria. Furthermore, we observed expansion of Paneth and goblet cells and presence of intermediate cells only in CONV and not GF mice. These findings provide evidence that manipulation and/or depletion of the enteric microbiota may have clinical significance in limiting chemotherapy-induced mucositis.

Microbes Infect 2015; 18:190-8.

Abstract
The Chlamydia muridarum induction of the upper genital tract pathology in mice has been used to investigate the mechanisms of chlamydial pathogenesis. We report that the NCF1 (neutrophil cytosolic factor1)-encoded p47phox (phagocyte oxidase), an essential subunit of nicotinamide adenine dinucleotide phosphate (NADPH)-oxidase, contributes significantly to C. muridarum induction of hydrosalpinx. Mice lacking p47phox (p47phox-deficient) were no longer able to develop significant hydrosalpinx following an intravaginal infection with C. muridarum. However, there was no significant difference in uterine horn dilation (as a result of the endometrial glandular duct dilation) between the p47phox-deficient and -sufficient mice. Thus, the role of NADPH oxidase in chlamydial pathogenesis is restricted to the oviduct tissue rather than the entire upper genital tract. Interestingly, both the p47phox-deficient and -sufficient mice displayed similar levels of chlamydial live organism shedding from the lower genital tract, suggesting that the NADPH oxidase is not required for the mouse control of chlamydial infection in the lower genital tract. Furthermore, the p47phox deficiency did not affect the infectious organism burden in the upper genital tract tissues, indicating that the NADPH-oxidase activity is not necessary for the mouse prevention of chlamydial ascension from the lower to upper genital tracts. However, the p47phox-defieicnt mice displayed a significantly reduced chronic inflammatory infiltration in the oviduct but not uterine tissues, supporting the finding that the NADPH oxidase activity is required for chlamydial induction of dilation in the oviduct but not the endometrial glandular duct. Thus, we have demonstrated a significant role of the host NADPH oxidase in promoting chronic inflammatory pathology in the oviduct following chlamydial infection.
