[PMID: 39299507 DOI: 10.1016/j.tox.2024.153954] [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: 08/02/2024] [Revised: 09/06/2024] [Accepted: 09/14/2024] [Indexed: 09/22/2024]
Abstract
Psoralen is a main active molecule of the traditional Chinese herb medicine Fructus Psoraleae. Our previous studies have shown that psoralen induced liver injury through the endoplasmic reticulum stress (ERS) signaling pathways. In this article, we studied whether the ERS inhibitor, 4-phenylbutyrate acid (4-PBA) could inhibit the liver toxicity caused by psoralen, and explored the underlying mechanisms. Mice were given the solvent, 20mg/kg, 40mg/kg, 80mg/kg of psoralen, or 80mg/kg of psoralen plus 4-PBA for 14 days. We found that 4-PBA significantly reduced the serum LDH and liver tissue MDA level, increased the activities of SOD and CAT, reduced liver weight and coefficient, repaired histopathological damage, and inhibited hepatocytes apoptosis induced by psoralen. RNA-seq transcriptomics found that except for the endoplasmic reticulum, the mitochondria was severely affected by psoralen. And genes involved in mitochondrial fusion, apoptosis, protein folding, and autophagy were found differently expressed in the psoralen group. Further studies found that 4-PBA inhibited the overexpression of GRP78 and CHOP, increased the Bcl-2/Bax ratio, and reduced the expression of Caspase-3. Moreover, 4-PBA reduced the overexpression of mitochondrial fission protein DRP1, increased the expression of fusion proteins Mfn-2 and OPA1, but has no inhibitory effects on autophagy proteins Atg5 or LC3A/B. In conclusion, 4-PBA inhibited ERS and reestablished mitochondrial fusion-fission balance, thereby blocking cell apoptosis, oxidative stress, and mitochondrial dysfunction, thus prevented against psoralen-induced hepatotoxicity.

Mechanism of Mitochondrial Kinetic Imbalance and Nrf2 Signaling Pathway-Mediated Oxidative Stress in Nickel and/or Chromium-Induced Kidney Injury in Mice. Antioxidants (Basel) 2024; 13:980. [PMID: 39199226 PMCID: PMC11351635 DOI: 10.3390/antiox13080980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2024] [Revised: 08/02/2024] [Accepted: 08/08/2024] [Indexed: 09/01/2024] Open
Abstract
Nickel and chromium are both common heavy metals that pose serious environmental and health hazards. However, the exact mechanism by which nickel and/or chromium cause renal injury is unclear. Therefore, we explored the molecular mechanisms of renal injury caused by nickel and/or chromium poisoning from the perspective of mitochondrial dynamics and the Nrf2 antioxidant pathway. In this study, eighty 6-week-old C57BL/6J mice were randomly divided into four groups: control (Con, untreated), nickel (Ni, 110 mg/L Ni2+), chromium (Cr, 50 mg/L Cr6+), and combined nickel-chromium (Ni + Cr, 110 mg/L Ni2+, 50 mg/L Cr6+). The results showed that chronic nickel and/or chromium exposure inhibited body weight gain and impaired kidney function and structure in mice. Chronic nickel and/or chromium exposure led to the disruption of mitochondrial dynamics and thus induced oxidative stress. On the other hand, the Nrf2 antioxidant pathway may play an important regulatory role in mitigating oxidative stress-induced oxidative damage in kidney. The present study partially elucidated the molecular mechanism of renal injury induced by nickel and/or chromium exposure in mice and the regulatory role of the Nrf2 pathway in inducing oxidative injury from the perspective of mitochondrial dynamics. This provides a theoretical basis for the development of prevention and control strategies, and environmental protection measures.

Abstract
Aluminum chloride is an inorganic polymeric coagulant commonly found in daily life and various materials. Although male reproductive toxicity has been associated with AlCl3 exposure, the underlying mechanism remains unclear. This study aimed to examine the impact of AlCl3 exposure on mitophagy and mitochondrial apoptosis in testicular tissue and mouse spermatocytes. Reactive oxygen species (ROS) and ATP levels were measured in GC-2spd after AlCl3 exposure using a multifunctional enzyme labeler. The changes in mitochondrial membrane potential (MMP) and TUNEL were observed through confocal laser microscopy, and the expression of proteins associated with mitophagy and apoptosis was analyzed using Western blot. Our results demonstrated that AlCl3 exposure disrupted mitophagy and increased apoptosis-related protein expression in testicular tissues. In the in vitro experiments, AlCl3 exposure induced ROS production, suppressed cell viability and ATP production, and caused a decrease in MMP, leading to mitophagy and cell apoptosis in GC-2spd cells. Intervention with N-acetylcysteine (NAC) reduced ROS production and partially restored mitochondrial function, thereby reversing the resulting mitophagy and cell apoptosis. Our findings provide evidence that ROS-mediated mitophagy and cell apoptosis play a crucial role in the toxicity of AlCl3 exposure in GC-2spd. These results contribute to the understanding of male reproductive toxicity caused by AlCl3 exposure and offer a foundation for future research in this area.

Abstract
Despite their similar physicochemical properties, recent studies have demonstrated that lanthanides can display different biological behaviors. Hence, the lanthanide series can be divided into three parts, namely early, mid, and late lanthanides, based on their interactions with biological systems. In particular, the late lanthanides demonstrate distinct, but poorly understood biological activity. In the current study, we employed genome-wide functional screening to help understand biological effects of exposure to Yb(III) and Lu(III), which were selected as representatives of the late lanthanides. As a model organism, we used Saccharomyces cerevisiae, since it shares many biological functions with humans. Analysis of the functional screening results indicated toxicity of late lanthanides is consistent with disruption of vesicle-mediated transport, and further supported a role for calcium transport processes and mitophagy in mitigating toxicity. Unexpectedly, our analysis suggested that late lanthanides target proteins with SH3 domains, which may underlie the observed toxicity. This study provides fundamental insights into the unique biological chemistry of late lanthanides, which may help devise new avenues toward the development of decorporation strategies and bio-inspired separation processes.

Ellagic acid ameliorates hexavalent chromium-induced renal toxicity by attenuating oxidative stress, suppressing TNF-α and protecting mitochondria. Toxicol Appl Pharmacol 2022; 454:116242.

Abstract
Nephrotoxicity is an important adverse effect of oxidative stress induced by hexavalent chromium [Cr(VI)]. The effect of ellagic acid, a dietary polyphenolic compound with potent antioxidant activity, was investigated in Cr(VI)-induced kidney injury. Six groups of male Wistar rats were treated intragastrically with vehicle or ellagic acid (15 and 30 mg/kg) for 10 days. On day 10, rats received saline or Cr(VI) (K2Cr2O7 15 mg/kg) subcutaneously. Cr(VI) significantly increased kidney weight, affected kidney function assessed by biomarkers in blood and urine (protein, creatinine and urea nitrogen), caused histological changes (tubular injury and glomerular capillary tuft damage), increased markers of oxidative stress and reduced the activity of antioxidant enzymes. In addition, Cr(VI) altered mitochondrial ultrastructure, impaired mitochondrial respiration, increased lipid peroxidation, and inhibited the function of mitochondrial enzymes. Pretreatment with ellagic acid (30 mg/kg) attenuated all the aforementioned alterations. Furthermore, we explored whether ellagic acid might regulate the tumor necrosis factor-alpha (TNF-α)/receptor-interacting protein kinase 3 (RIPK3) pathway, reducing Cr(VI)-induced tubular necrosis. Cr(VI) upregulated both TNF-α and RIPK3, but ellagic acid only decreased TNF-α levels, having no effect on RIPK3 content. Therefore, understanding the mechanisms through which Cr(VI) promotes necroptosis is crucial for future studies, in order to design strategies to mitigate kidney damage. In conclusion, ellagic acid attenuated Cr(VI)-induced renal alterations by preventing oxidative stress, supporting enzymatic activities, suppressing TNF-α, and preserving mitochondrial ultrastructure and function, most likely due to its antioxidant properties.

Abstract
Trivalent chromium (Cr(III)) and hexavalent chromium (Cr(VI)) are the two mainly stable oxidation states of Cr in aquatic environments, while the difference of their bioavailability and toxicity by dietary exposure has been rarely known in aquatic organisms. Using juvenile coral trout (Plectropomus leopardus), Cr(III) and Cr(VI) as model system, this study tested the hypothesis that the dietary Cr bioaccumulation and toxicity in fish were highly dependent on Cr speciation. The fish were chronically exposed to 200 mg kg-1 of dietary Cr(III) and Cr(VI) for 8 weeks, and then the Cr bioaccumulation, morphologic change, and RNA-Seq in fish liver were determined. The results showed that dietary Cr(III) and Cr(VI) exposure significantly induced fish weight gain, while 1.17 folds and 1.26 folds increased in relation to Control group, respectively. Cr contents in liver was increased significantly in dietary Cr(VI) but not in Cr(III) groups. Both Cr treatment induced lipid deposition in liver tissue structure, moreover, pancreatic part was increased in dietary Cr(III) but its reduced in Cr(VI) exposure. RNA-Seq in fish liver were significantly different as well. Specifically, there were 138 differentially expressed genes (DEGs) in dietary Cr(III) group, including 76 up-regulated and 62 down-regulated, and these DEGs were mainly involved in lipid metabolism, while there were 175 DEGs in dietary Cr(VI) group, including 85 up-regulated and 90 down-regulated, and these DEGs were mainly involved in immune system. The qRT-PCR confirmed the RNA-seq data were reliable. Overall, these results supported our hypothesis that the chronic dietary Cr(III) and Cr(VI) exposure resulted in apparently different Cr bioaccumulation and toxicity in fish. Our findings here help us to fill in a big gap in our knowledge of speciation-specific Cr bioavailability and toxicity in aquatic organisms, which has been largely unclear previously. CAPSULE: Dietary Cr(III) increased lipid metabolism and dietary Cr(VI) activated immune system in liver of coral trout at transcription levels.

Abstract
The aim of this study is to determine whether Cr(VI) can induce inflammatory injury in chicken brain and influence mitophagy and related mechanisms. A total of 120 hyline brown chickens (1 day old, 20±3g) were selected and randomly divided into four groups and given different doses of Cr(VI) (0, 10, 30, and 50 mg/kg) every day at 45 days. Results showed that excessive intake of Cr(VI) led to increased tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) levels and decreased interferon-gamma (IF-γ) level. Cr(VI) increased the production of mitochondrial reactive oxygen species (ROS) in chicken brain cells, causing the decline of mitochondrial membrane potential (MMP) and formation of autophagosomes for mitophagy. In addition, Cr(VI) promoted the translocation of Parkin to the mitochondrial outer membrane, increased LC3-II protein level, and inhibited p62 and TOM20 protein expression. In conclusion, excessive Cr(VI) intake can induce inflammatory injury and mitophagy in chicken brain.
