Cadmium is a nonessential metal that has heavily polluted the environment due to human activities. It can be absorbed into the human body via the gastrointestinal tract, respiratory tract, and the skin, and can cause chronic damage to the kidneys. The main site where cadmium accumulates and causes damage within the nephrons is the proximal tubule. This accumulation can induce dysfunction of the mitochondrial electron transport chain, leading to electron leakage and production of reactive oxygen species (ROS). Cadmium may also impair the function of NADPH oxidase, resulting in another source of ROS. These ROS together can cause oxidative damage to DNA, proteins, and lipids, triggering epithelial cell death and a decline in kidney function. In this article, we also reviewed evidence that the antioxidant power of plant extracts, herbal medicines, and pharmacological agents could ameliorate cadmium-induced kidney injury. Finally, a model of cadmium-induced kidney injury, centering on the notion that oxidative damage is a unifying mechanism of cadmium renal toxicity, is also presented. Given that cadmium exposure is inevitable, further studies using animal models are warranted for a detailed understanding of the mechanism underlying cadmium induced ROS production, and for the identification of more therapeutic targets.

Currently in Europe, despite the many advances in production technology of synthetic drugs, the interest in natural herbal medicines continues to increase. One of the reasons for their popular use is the assumption that natural equals safe. However, herbal medicines contain pharmacologically active ingredients, some of which have been associated with adverse effects. Kidneys are particularly susceptible to injury induced by toxins, including poisonous constituents from medicinal plants. The most recognized herb-induced kidney injury is aristolochic acid nephropathy connected with misuse of certain Traditional Chinese herbal medicines. Data concerning nephrotoxicity of plant species of European origin are scarce. Here, we critically review significant data of the nephrotoxicity of several plants used in European phytotherapy, including Artemisia herba-alba, Glycyrrhiza glabra, Euphorbia paralias, and Aloe). Causative mechanisms and factors predisposing to intoxications from the use of herbs are discussed. The basic intention of this review is to improve pharmacovigilance of herbal medicine, especially in patients with chronic kidney diseases.

Methotrexate is an antimetabolic drug with a myriad of serious side effects including nephrotoxicity, which presumably occurs due to oxidative tissue damage. Here, we evaluated the potential protective effect of lycopene, a potent antioxidant carotenoid, given in two different pharmaceutical forms in methotrexate-induced kidney damage in rats. Serum biochemical (urea and creatinine) and tissue oxidative damage markers and histopathological kidney changes were evaluated after systemic administration of both lycopene dissolved in corn oil and lycopene encapsulated in nanoliposomes. Similar to previous studies, single dose of methotrexate induced severe functional and morphological alterations of kidneys with cell desquamation, tubular vacuolation, and focal necrosis, which were followed by serum urea and creatinine increase and disturbances of tissue antioxidant status. Application of both forms of lycopene concomitantly with methotrexate ameliorated changes in serum urea and creatinine and oxidative damage markers and markedly reversed structural changes of kidney tissue. Moreover, animals that received lycopene in nanoliposome-encapsulated form showed higher degree of recovery than those treated with free lycopene form. The findings of this study indicate that treatment with nanoliposome-encapsulated lycopene comparing to lycopene in standard vehicle has an advantage as it more efficiently reduces methotrexate-induced kidney dysfunction.

One-electron oxidation of DNA results in chemical damage to nucleobases, particularly guanine in multiple G sequences. Oxidation may be triggered by numerous events, including photosensitization. We describe studies of photoinduced oxidations of DNA triggered by irradiation of covalently linked anthraquinone derivatives under various conditions that affect the global structure of the DNA. These structural changes have subtle effects on the result of the one-electron oxidation.

Abstract Acute kidney injury induced by cisplatin poses a serious health hazard to patients. Thus, this study was undertaken to elucidate key signaling pathways and hub genes relevant for therapeutic intervention involved in cisplatin-induced acute kidney injury(CI-AKI) by bioinformatics. We identified differentially expressed genes(DEGs) by R language on GSE106993 and GSE153625 datasets, downloaded from Gene Expression Omnibus (GEO). GO enrichment analysis and KEGG analysis were used to identify the main functions of common differential genes. The STRING database was used to construct protein-protein interaction (PPI) networks and hub genes were selected by Cytoscape. TransmiR v2.0 database and miRWalk2.0 database were used to construct transcription factor (TF)/microRNA (miRNA)/mRNA networks. Chinese herbal medicines targeting hub genes were screened by the ETMC database. 817 up-regulated genes and 769 down-regulated genes were obtained in CI-AKI model. Tumor necrosis factor(TNF) signaling pathway, P53 signaling, and metabolic signaling pathway are important pathways in CI-AKI. 8 hub genes were identified through PPI (Trp53、Egf、Stat3、Jun、Casp3、Cdh1、Ptgs2、Cat). We also constructed TF/microRNA/mRNA regulatory networks, including 2 TFs, 4 miRNAs and 214 mRNAs. The results of ETMC database analysis showed that Sang-Ye and Ban-Xia could be used for the treatment of CI-AKI. In this study, we identified 8 hub genes and 3 important signaling pathways in CI-AKI model by bioinformatics analysis, which provide targets for the treatment of CI-AKI. And the two Chinese herbal medicines obtained from our research, Sang-Ye and Ban-Xia, are expected to be used for the treatment of CI-AKI. Meanwhile, the TF/miRNA/mRNA networks we constructed are helpful to the further study of the mechanism of CI-AKI.

A scientific session entitled “New Frontiers: Approaches to Understand the Mechanistic Basis of Renal Toxicity” focused on novel biomarkers to monitor kidney injury both preclinically and clinically, as well as providing mechanistic insight of the induced injury. Further, the role and impact of kidney membrane transporters in drug-induced kidney toxicity provided additional considerations when understanding kidney injury and the complex role of drug transporters in either sensitivity or resistance to drug-induced injury. The onset of nephropathy in diabetic patients was also presented, focusing on the quest to discover novel biomarkers that would differentiate diabetic populations more susceptible to nephropathy and renal failure. The session highlighted exciting new research areas and novel biomarkers that will enhance our understanding of kidney injury and provide tools for ensuring patient safety clinically.
