Catalpol-Induced AMPK Activation Alleviates Cisplatin-Induced Nephrotoxicity through the Mitochondrial-Dependent Pathway without Compromising Its Anticancer Properties. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:7467156. [PMID: 33510841 PMCID: PMC7826214 DOI: 10.1155/2021/7467156] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Revised: 11/15/2020] [Accepted: 12/24/2020] [Indexed: 01/19/2023]
Abstract
Nephrotoxicity is a common complication of cisplatin chemotherapy and, thus, limits the clinical application of cisplatin. In this work, the effects of catalpol (CAT), a bioactive ingredient extracted from Rehmannia glutinosa, on cisplatin-induced nephrotoxicity and antitumor efficacy were comprehensively investigated. Specifically, the protective effect of CAT on cisplatin-induced injury was explored in mice and HK-2 cells. In vivo, CAT administration strikingly suppressed cisplatin-induced renal dysfunction, morphology damage, apoptosis, and inflammation. In vitro, CAT induced activation of adenosine 5′-monophosphate- (AMP-) activated protein kinase (AMPK), improved mitochondrial function, and decreased generation of cellular reactive oxygen species (ROS), leading to a reduction in inflammation and apoptosis, which ultimately protected from cisplatin-induced injury. However, the beneficial effects of CAT were mostly blocked by coincubation with compound C. Furthermore, molecular docking results indicated that CAT had a higher affinity for AMPK than other AMPK activators such as danthron, phenformin, and metformin. Importantly, CAT possessed the ability to reverse drug resistance without compromising the antitumor properties of cisplatin. These findings suggest that CAT exerts positive effects against cisplatin-induced renal injury through reversing drug resistance via the mitochondrial-dependent pathway without affecting the anticancer activity of cisplatin.

Poly(ADP-ribose) polymerase-1 inhibitor ameliorates dextran sulfate sodium-induced colitis in mice by regulating the balance of Th17/Treg cells and inhibiting the NF- κB signaling pathway. Exp Ther Med 2020; 21:134. [PMID: 33376516 PMCID: PMC7751469 DOI: 10.3892/etm.2020.9566] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Accepted: 11/13/2020] [Indexed: 02/06/2023] Open
Abstract
Poly(ADP-ribose) polymerase-1 (PARP-1) plays a critical role in inflammatory pathways. The PARP-1 inhibitor, 5-aminoisoquinolinone (5-AIQ), has been demonstrated to exert significant pharmacological effects. The present study aimed to further examine the potential mechanisms of 5-AIQ in a mouse model of dextran sodium sulfate (DSS)-induced colitis. Colitis conditions were assessed by changes in weight, disease activity index, colon length, histopathology and pro-inflammatory mediators. The colonic expression of PARP/NF-κB and STAT3 pathway components was measured by western blot analysis. Flow cytometry was used to analyze the proportion of T helper 17 cells (Th17) and regulatory T cells (Tregs) in the spleen. Western blot analysis and reverse transcription-quantitative PCR were employed to determine the expression of the transcription factors retinoic acid-related orphan receptor and forkhead box protein P3. The results demonstrated that 5-AIQ reduced tissue damage and the inflammatory response in mice with experimental colitis. Moreover, 5-AIQ increased the proportion of Treg cells and decreased the percentage of Th17 cells in the spleen. Furthermore, following 5-AIQ treatment, the main components of the PARP/NF-κB and STAT3 pathways were downregulated. Collectively, these results demonstrate that the PARP-1 inhibitor, 5-AIQ, may suppress intestinal inflammation and protect the colonic mucosa by modulating Treg/Th17 immune balance and inhibiting PARP-1/NF-κB and STAT3 signaling pathways in mice with experimental colitis.

Abstract
Cisplatin is an effective chemotherapeutic drug whose clinical use and efficacy are limited by its nephrotoxicity, which affects mainly the renal tubules and vasculature. It accumulates in proximal and distal epithelial tubule cells and causes oxidative stress-mediated cell death and malfunction. Consequently, many antioxidants have been tested for their capacity to prevent cisplatin nephrotoxicity. In this study, we made a systematic review of the literature and meta-analyzed 152 articles, which tested the nephroprotective effect of isolated compounds or mixtures of natural origin on cisplatin nephrotoxicity in preclinical models. This meta-analysis identified the most effective candidates and examined the efficacy obtained by antioxidants administered by the oral and intraperitoneal routes. By comparing with a recent, similar meta-analysis performed on clinical studies, this article identifies a disconnection between preclinical and clinical research, and contextualizes, discusses, and integrates the existing preclinical information toward the optimized selection of candidates to be further explored (clinical level). Despite proved efficacy, this article discusses the barriers limiting the clinical development of natural mixtures, such as those in extracts from Calendula officinalis flowers and Heliotropium eichwaldii roots. On the contrary, isolated compounds are more straightforward candidates, among which arjunolic acid and quercetin stand out in this meta-analysis.

Abstract
OBJECTIVES To investigate the protective effect of vanillin in cisplatin (CP)-induced nephrotoxicity in rats and elucidate the role of nrf-2 and its downstream antioxidant molecules. METHODS Rats received vanillin (100 mg/kg orally) for 10 constitutive days and CP (7.5 mg/kg, once, ip) on day 6 of vanillin administration. KEY FINDINGS Cisplatin suppressed body weight gain, increased serum urea and creatinine and renal malondialdehyde and nitric oxide while decreased renal total antioxidant capacity. Up-regulation of NADPH oxidase-4 (NOX-4) was marked in renal tissue of CP-treated rats along with down-regulation of the antioxidant genes (nuclear factor erythroid 2-related factor2 (NRF2) and haem oxygenase-1(HO-1)). Increased tumour necrosis factor-α and decreased interleukin-10 with increased myeloperoxidase activity were apparent in renal tissue of CP-treated rats along with marked tubular injury, neutrophil infiltration and increased apoptosis (caspase-3) and some degree of interstitial fibrosis. Vanillin prophylactic administration prevented the deterioration of kidney function, oxidative and nitrosative stress. It also suppressed NOX-4 and up-regulated NRF2 and HO-1 expression in renal tissue. Inflammation, apoptosis and tubular injury were also inhibited by vanillin. CONCLUSIONS The antioxidant mechanism by which vanillin protected against CP-induced nephrotoxicity involved the inhibition of NOX-4 along with the stimulation of Nrf2/HO-1 signalling pathway. These in turn inhibited inflammation and apoptosis.

Abstract
Taurine (2-aminoethanesulfonic acid) is a sulfur-containing organic acid possessing several important effects, including antioxidant and anti-inflammatory ones. Exposure to ionizing radiation generates free radicals and reactive oxygen species (ROS) in irradiated cells, and free radical generation leads to oxidative stress. It is known that radiation nephropathy includes an inflammation-based process in which ROS and cytokines are responsible. Different doses of explored radiation can cause apoptosis, inflammation and a profound oxidative stress in kidneys. Oxidative stress is involved in renal injury after exposure to both ionizing radiation and inflammation. In this review, we describe the protective effect of taurine against several kidney diseases and the potential effects of taurine in the mitigation of radiation nephropathy. We also report that X-irradiation decreased the expression of taurine and TauT in the kidney. Taurine administration suppressed the decrease in the expression of taurine and TauT in the kidney after radiation exposure. Taurine might contribute to the mitigation of kidney injury induced by radiation.

Abstract
BACKGROUND Cisplatin (Cis), is a potent chemotherapeutic drug. However, Cis nephrotoxicity is high, thus limiting its use. Platelet-rich plasma (PRP) is an autologous product, easy to get from blood centrifugation. The aim of this study is to investigate the effects of PRP in reversing Cis-induced nephrotoxicity. MATERIALS AND METHODS Thirty-two adult albino rats were distributed into Group I, the control group; Group II, in which the rats received Cis (5 mg·kg-1 ·day -1 , intraperitoneal); Group III and Group IV, in which the rats received Cis, followed by normal saline and PRP distribution, respectively (1 ml) over the renal surface 24 hr later. All rats were killed on the eighth day of the experiment. Histopathological changes were examined. RESULTS Glomerular atrophy, tubular degeneration, interrupted PAS reaction, highly expressed caspase-3, and ultra-structural changes were observed after Cis injection, which improved with PRP administration. CONCLUSION PRP reduced acute kidney injury through the epithelial GFs.
