Reno-protective effect of nicorandil and pentoxifylline against potassium dichromate-induced acute renal injury via modulation p38MAPK/Nrf2/HO-1 and Notch1/TLR4/NF-κB signaling pathways. J Trace Elem Med Biol 2024; 85:127474. [PMID: 38788404 DOI: 10.1016/j.jtemb.2024.127474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 04/09/2024] [Accepted: 05/16/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND Occupational and environmental exposure to chromium compounds such as potassium dichromate (PDC) (K2Cr2O7) has emerged as a potential aetiologic cause for renal disease through apoptotic, and inflammatory reactions. The known potent antioxidants such as nicorandil (NIC) and/or pentoxifylline (PTX) were studied for their possible nephroprotective effect in PDC-treated rats. METHODS Forty male Wistar rats were divided into five groups; control, PDC group, NIC+PDC, PTX+PDC group, and combination+PDC group. Nephrotoxicity was evaluated histopathologically and biochemically. Invasive blood pressure, renal function parameters urea, creatinine, uric acid and albumin, glomerular filtration rate markers Cys-C, Kim-1 and NGAL, inflammatory markers IL-1β, IL-6, TNF-α, TGF-β, COX-II, p38MAPK, NF-κB and TLR4, oxidative stress SOD, GSH, MDA, MPO, HO-1 and Nrf2 and apoptotic mediators Notch1 and PCNA were evaluated. Besides, renal cortical histopathology was assayed as well. RESULTS PDC led to a considerable increase in indicators for kidney injury, renal function parameters, invasive blood pressure, oxidative stress, and inflammatory markers. They were markedly reduced by coadministration of PDC with either/or NIC and PTX. The NIC and PTX combination regimen showed a more significant improvement than either medication used alone. Our results demonstrated the nephroprotective effect of NIC, PTX, and their combined regimen on PDC-induced kidney injury through suppression of oxidative stress, apoptosis, and inflammatory response. CONCLUSION Renal recovery from PDC injury was achieved through enhanced MAPK/Nrf2/HO-1 and suppressed Notch1/TLR4/NF-κB signaling pathways. This study highlights the role of NIC and PTX as effective interventions to ameliorate nephrotoxicity in patients undergoing PDC toxicity.

Abstract
BACKGROUND Vancomycin (VCM) is used clinically to treat serious infections caused by multi-resistant Gram-positive bacteria, although its use is severely constrained by nephrotoxicity. This study investigated the possible nephroprotective effect of febuxostat (FX) and/or fenofibrate (FENO) and their possible underlying mechanisms against VCM-induced nephrotoxicity in a rat model. METHODS Male Wistar rats were randomly allocated into five groups; Control, VCM, FX, FENO, and combination groups. Nephrotoxicity was evaluated histopathologically and biochemically. The oxidative stress biomarkers (SOD, MDA, GSH, total nitrite, GPx, MPO), the apoptotic marker, renal Bcl-2 associated X protein (Bax), and inflammatory and kidney injury markers (IL-1β, IL-6, TNF-α, Nrf2, OH-1, kappa-light-chain-enhancer of activated B cells (NF-κB), NADPH oxidase, Kim-1, COX-II, NGAL, Cys-C were also evaluated. RESULTS VCM resulted in significant elevation in markers of kidney damage, oxidative stress, apoptosis, and inflammatory markers. Co-administration of VCM with either/or FX and FENO significantly mitigated nephrotoxicity and associated oxidative stress, inflammatory and apoptotic markers. In comparison to either treatment alone, a more notable improvement was observed with the FX and FENO combination regimen. CONCLUSION Our findings show that FX, FENO, and their combination regimen have a nephroprotective impact on VCM-induced kidney injury by suppressing oxidative stress, apoptosis, and the inflammatory response. Renal recovery from VCM-induced injury was accomplished by activation of Nrf2/HO-1 signaling and inhibition of NF-κB expression. This study highlights the importance of FX and FENO as effective therapies for reducing nephrotoxicity in VCM-treated patients.

Ameliorative effects of sinapic acid against vancomycin-induced testicular oxidative damage, apoptosis, inflammation, testicular histopathologic disorders and decreased epididymal sperm quality. Reprod Toxicol 2024; 129:108666. [PMID: 39059777 DOI: 10.1016/j.reprotox.2024.108666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2024] [Revised: 07/09/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024]
Abstract
In this study, it was aimed to determine the effect of sinapic acid (SNP), a polyphenol with antioxidant, anti-inflammatory and antibacterial properties, on testicular damage caused by vancomycin (VCM), a widely used antibiotic against gram positive bacteria. A total of 35 male Sprague Dawley rats were used in the study, divided into five groups: control, VCM, SNP, VCM + SNP 10, and VCM + SNP 20. Following a week of oral administration, the rats were euthanized under sevoflurane anesthesia. While the VCM group had a significant increase in MDA levels, the SNP administration inhibited the increase in MDA levels. VCM led to a significant decrease in GSH levels, SOD, CAT, and GPx activity in the testicular tissue of rats, while SNP administration increased these antioxidant levels. SNP administration decreased the mRNA expression levels of VCM induced Nrf-2, HO-1, and NQO1 in testicular tissue while increasing the levels of MAPK14, MAPK15, JNK, P53, Apaf-1, Caspase-3, Caspase-6, Caspase-9, and Beclin-1 mRNA transcript levels. The VCM group showed a significant increase in Bax and NF-κB levels in testicular tissue, while Bcl-2 levels decreased. VCM significantly decreased sperm motility and increased the percentage of damaged sperm in rats. Histopathological results revealed that VCM caused disruption of basement membranes and disorganization of seminiferous tubules, but SNP administration preserved testicular histology. As a result, VCM increased oxidative stress, apoptosis, and autophagy in the testicular tissue of rats, altered testicular histopathology, and decreased sperm quality, while SNP decreased these effects.

Abstract
Objective The present study was designed to investigate the nephroprotective and immunoprotective effects of S-adenosyl-L-methionine (SAMe) in comparison to N-acetylcysteine (NAC) against ochratoxin A (OTA) - intoxication. Methods Forty-eight adult male Sprague-Dawley rats were categorized into four groups: Control; OTA intoxication (5 mg OTA/kg diet); OTA + NAC, rats received 200 mg NAC/day before feeding balanced diet contaminated with OTA; and (OTA + SAMe). Rats received 200 mg SAMe/day dissolved in distilled water orally just before feeding a balanced diet contaminated with OTA. Results OTA administration altered serum kidney function biomarkers. These effects were pronouncedly alleviated by treatment with NAC. Results revealed a correlation between OTA-induced immunotoxicity and the reduced white blood cell (WBC) count. Treatments with SAMe significantly improved the WBCs count and hemoglobin concentration. Conclusion NAC and SAMe have a protective role against nephrotoxicity and immunotoxicity induced by continuous administration of OTA. NAC was more effective in reducing OTA nephrotoxicity, whereas SAMe was more potent than NAC in reducing OTA immunotoxicity.

Abstract
Dexmedetomidine (DEX) is a highly selective and potent α2-adrenoceptor (α2-AR) agonist that is widely used as a clinical anesthetic to induce anxiolytic, sedative, and analgesic effects. In recent years, a growing body of evidence has demonstrated that DEX protects against acute kidney injury (AKI) caused by sepsis, drugs, surgery, and ischemia-reperfusion (I/R) in organs or tissues, indicating its potential role in the prevention and treatment of AKI. In this review, we summarized the evidence of the renoprotective effects of DEX on different models of AKI and explored the mechanism. We found that the renoprotective effects of DEX mainly involved antisympathetic effects, reducing inflammatory reactions and oxidative stress, reducing apoptosis, increasing autophagy, reducing ferroptosis, protecting renal tubular epithelial cells (RTECs), and inhibiting renal fibrosis. Thus, the use of DEX is a promising strategy for the management and treatment of perioperative AKI. The aim of this review is to further clarify the renoprotective mechanism of DEX to provide a theoretical basis for its use in basic research in various AKI models, clinical management, and the treatment of perioperative AKI.

Abstract
Vancomycin, is widely used against methicillin-resistant bacterial infections. However, Vancomycin accumulation causes nephrotoxicity which leads to an impairment in the filtration mechanisms of kidney. Traditional herbal medicines hold potential for treatment of drug-induced nephrotoxicity. Herein, we investigated protective properties of plant-based medicine Renogrit against Vancomycin-induced kidney injury. Phytometabolite analysis of Renogrit was performed by UHPLC. Spheroids formed from human proximal tubular cell (HK-2) were used for in vitro evaluation of Vancomycin-induced alterations in cell viability, P-gp functionality, NAG, KIM-1 levels, and mRNA expression of NGAL and MMP-7. The in vivo efficacy of Renogrit against Vancomycin-induced nephrotoxicity was further evaluated in Sprague-Dawley (SD) rats by measurement of BUN, serum creatinine, and their respective clearances. Moreover, eGFR, kidney-to-body weight ratio, GSH/GSSG ratio, KIM-1, NAG levels and mRNA expression of KIM-1 and osteopontin were also analyzed. Changes in histopathology of kidney and hematological parameters were also observed. Renogrit treatment led to an increase in cell viability, normalization of P-gp functionality, decrease in levels of NAG, KIM-1, and reduction in mRNA expression of NGAL and MMP-7. In Vancomycin-challenged SD rats, Renogrit treatment normalized altered kidney functions, histological, and hematological parameters. Our findings revealed that Renogrit holds a clinico-therapeutic potential for alleviating Vancomycin-associated nephrotoxicity.

Abstract
High levels of reactive oxygen species (ROS) lead to progressive deterioration of mitochondrial function, resulting in tissue degeneration. In this study, ROS accumulation induced nucleus pulposus cells (NPCs) senescence is observed in degenerative human and rat intervertebral disc, suggesting senescence as a new therapeutic target to reverse intervertebral disc degeneration (IVDD). By targeting this, dual-functional greigite nanozyme is successfully constructed, which shows the ability to release abundant polysulfides and presents strong superoxide dismutase and catalase activities, both of which function to scavenge ROS and maintain the tissue at physical redox level. By significantly lowering the ROS level, greigite nanozyme rescues damaged mitochondrial function in IVDD models both in vitro and in vivo, rescues NPCs from senescence and alleviated the inflammatory response. Furthermore, RNA-sequencing reveals ROS-p53-p21 axis is responsible for cellular senescence-induced IVDD. Activation of the axis abolishes greigite nanozyme rescued NPCs senescence phenotype, as well as the alleviated inflammatory response to greigite nanozyme, which confirms the role of ROS-p53-p21 axis in greigite nanozyme's function to reverse IVDD. In conclusion, this study demonstrates that ROS-induced NPCs senescence leads to IVDD and the dual-functional greigite nanozyme holds strong potential to reverse this process, providing a novel strategy for IVDD management.

Abstract
Aluminum (Al) is a common environmental pollutant that can induce kidney damage. However, the mechanism is not clear. In the present study, to explored the exact mechanism of AlCl3-induced nephrotoxicity, C57BL/6 N male mice and HK-2 cells were used as experimental subjects. Our results showed that Al induced reactive oxygen species (ROS) overproduction, c-Jun N-terminal kinase (JNK) signaling activation, RIPK3-dependent necroptosis, NLRP3 inflammasome activation, and kidney damage. In addition, inhibiting JNK signaling could downregulate the protein expressions of necroptosis and NLRP3 inflammasome, thereby alleviating kidney damage. Meanwhile, clearing ROS effectively inhibited JNK signaling activation, which in turn inhibited necroptosis and NLRP3 inflammasome activation, ultimately alleviating kidney damage. In conclusion, these findings suggest that necroptosis and NLPR3 inflammasome activation mediated by ROS/JNK pathway participate in AlCl3-induced kidney damage.

Abstract
INTRODUCTION Melatonin is a hormone synthesized by the pineal gland, and has antioxidative effects in reducing acute kidney injury (AKI). In the past three years, an increasing number of studies have evaluated whether melatonin has a protective effect on AKI. The study systematically reviewed and assessed the efficacy and safety of melatonin in preventing AKI. MATERIAL AND METHODS A systematic literature search was conducted in the PubMed, Embase, and Web of Science databases on February 15, 2023. Eligible records were screened according to the inclusion and exclusion criteria. The odds ratio and Hedges' gwith the corresponding 95% confidence intervals were selected to evaluate the effects of melatonin on AKI. We pooled extracted data using a fixed- or random-effects model based on a heterogeneity test. RESULTS There were five studies (one cohort study and four randomized controlled trials) included in the meta-analysis. Although the glomerular filtration rate (GFR) may be significantly improved by melatonin, the incidence of AKI was not significantly decreased in the melatonin group compared with the control group in randomized controlled trials (RCTs). CONCLUSIONS In our study, the present results do not support a direct effect of melatonin use on the reduction of AKI. More well-designed clinical studies with larger sample size are required in the future.

Abstract
Background and Objectives: Numerous studies have indicated that antibiotics may adversely affect testicular and sperm function. As an alternative to penicillin, vancomycin is a glycopeptide antibiotic developed to treat resistant strains of Staphylococcus aureus. A few studies have suggested that vancomycin could cause testicular toxicity and apoptosis. Vancomycin, however, has not been investigated in terms of its mechanism of causing testicular toxicity. Materials and Methods: An experiment was conducted to investigate the effects of resveratrol (20 mg/kg, oral gavage) against vancomycin (200 mg/kg, i.p.) on the testicular function of Wistar rats for one week (7 days). There were three subgroups of animals. First, saline (i.p.) was administered to the control group. Then, in the second group, vancomycin was administered. Finally, vancomycin and resveratrol were administered in combination in the third group. Results: After seven days of vancomycin treatment, testosterone levels, sperm counts, and sperm motility were significantly reduced, but resveratrol attenuated the effects of vancomycin and restored the testosterone levels, sperm counts, and sperm motility to normal. In the presence of resveratrol, the vancomycin effects were attenuated, and the luteinizing hormone and follicular hormone levels were normalized after seven days of treatment with vancomycin. Histologically, vancomycin administration for seven days caused damage to testicular tissues and reduced the thickness of the basal lamina. However, the resveratrol administration with vancomycin prevented vancomycin’s toxic effects on testicular tissue. Conclusion: Resveratrol showed potential protective effects against vancomycin-induced testicular toxicity in Wistar rats.
