J Clin Med 2021; 10:jcm10020271. [PMID: 33450989 PMCID: PMC7828445 DOI: 10.3390/jcm10020271] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 01/05/2021] [Accepted: 01/11/2021] [Indexed: 11/16/2022] Open
Abstract
Gadolinium-based contrast media (GBCM) toxicity in patients with kidney disease is a concern for the possible development of systemic nephrogenic fibrosis and possible renal complications. This review focuses on the pathological mechanisms underlying the potential kidney toxicity of gadolinium. Gadolinium, as a free compound (Gd3+), is highly toxic in humans because it competes with divalent calcium (Ca2+) and magnesium (Mg2+) ions, interfering in some relevant biologic processes. Its toxicity is blunted by the complexing of Gd3+ with a carrier, allowing its use in magnetic resonance imaging. The binding reaction between gadolinium and a carrier is thermodynamically reversible. Consequently, under some conditions, gadolinium can be released in the interstitial space as a free Gd3+ compound with the possibility of toxicity. Other metals such as iron, copper, and calcium can interfere with the binding between gadolinium and its carrier because they compete for the same binding site. This process is known as transmetallation. In patients with kidney impairment, conditions such as low clearance of the Gd-carrier complex, acid-base derangements, and high serum phosphorous can increase the presence of free Gd3+, leading to a higher risk for toxicity.

Li H, Li S, Yang H, Wang Y, Wang J, Zheng N. l-Proline Alleviates Kidney Injury Caused by AFB1 and AFM1 through Regulating Excessive Apoptosis of Kidney Cells. Toxins (Basel) 2019; 11:toxins11040226. [PMID: 30995739 PMCID: PMC6521284 DOI: 10.3390/toxins11040226] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 04/07/2019] [Accepted: 04/15/2019] [Indexed: 11/21/2022] Open
Abstract
The toxicity and related mechanisms of aflatoxin B1 (AFB1) and aflatoxin M1 (AFM1) in the mouse kidney were studied, and the role of l-proline in alleviating kidney damage was investigated. In a 28-day toxicity mouse model, thirty mice were divided into six groups: control (without treatment), l-proline group (10 g/kg body weight (b.w.)), AFB1 group (0.5 mg/kg b.w.), AFM1 (3.5 mg/kg b.w.), AFB1 + l-proline group and AFM1 + l-proline group. Kidney index and biochemical indicators were detected, and pathological staining was observed. Using a human embryonic kidney 293 (HEK 293) cell model, cell apoptosis rate and apoptotic proteins expressions were detected. The results showed that AFB1 and AFM1 activated pathways related with oxidative stress and caused kidney injury; l-proline significantly alleviated abnormal expressions of biochemical parameters and pathological kidney damage, as well as excessive cell apoptosis in the AF-treated models. Moreover, proline dehydrogenase (PRODH) was verified to regulate the levels of l-proline and downstream apoptotic factors (Bax, Bcl-2, and cleaved Caspase-3) compared with the control (p < 0.05). In conclusion, l-proline could protect mouse kidneys from AFB1 and AFM1 through alleviating oxidative damage and decreasing downstream apoptosis, which deserves further research and development.

Abstract
The toxic effects and potential mechanisms of aflatoxin B1 (AFB1), aflatoxin M1 (AFM1), and AFB1+AFM1 in the kidney were studied and compared in HEK 293 cells model and CD-1 mice model. The 35-day subacute toxicity mice model was constructed, biochemical indicators and kidney pathological staining were detected, kidney metabonomics detection was performed, and the metabolites were analyzed, and then the related toxicity mechanism was validated. Results showed that AFB1 (0.5 mg/kg), AFM1 (3.5 mg/kg), and AFB1 (0.5 mg/kg)+AFM1 (3.5 mg/kg) activated oxidative stress and caused renal damage. The relative concentration of the metabolite L-proline was found to be lower in aflatoxins treatment groups when compared with the control (P < 0.05). Moreover, with the treatment of aflatoxins, proline dehydrogenase (PRODH) and proapoptotic factors (Bax, Caspase-3) were upregulated, while the inhibitor of apoptosis Bcl-2 was downregulated, at both the mRNA and the protein levels, comparing with the control (P < 0.05). In addition, the combined effect of AFB1 and AFM1 was validated, for the toxicity of the combination was stronger than the other two groups. In conclusion, AFB1 and AFM1 caused kidney toxicity by activating oxidative stress through altering expression of PRODH and L-proline levels, which then induced downstream apoptosis.

Abstract
We reported previously that complete spinal cord transection (SCT) results in depression of mitochondrial respiratory chain enzyme activity that triggers apoptosis via sequential activations of apoptosis-inducing factor (AIF)- and caspase-dependent cascades in the injured spinal cord. This study tested the hypothesis that nitric oxide (NO) and superoxide anion (O(2)(.-)) serve as the interposing signals between SCT and impaired mitochondrial respiratory functions. Adult Sprague-Dawley rats manifested a significant increase in NO or O(2)(.-) level in the injured spinal cord during the first 3 days after SCT. The augmented O(2)(.-) production, along with concomitant reduction in mitochondrial respiratory chain enzyme activity or ATP level, nuclear translocation of AIF, cytosolic release of cytochrome c, and DNA fragmentation were reversed by osmotic minipump infusion of a NO trapping agent, carboxy-PTIO, or a superoxide dismutase mimetic, tempol, into the epicenter of the transected spinal cord. Intriguingly, carboxy-PTIO significantly suppressed upregulation of poly(ADP-ribose) polymerase-1 (PARP-1) in the nucleus, attenuated nuclear translocation of AIF, inhibited mitochondrial translocation of Bax and antagonized mitochondrial release of cytochrome c; whereas tempol only inhibited the later two cellular events after SCT. We conclude that overproduction of NO and O(2)(.-) in the injured spinal cord promulgates mitochondrial dysfunction and triggers AIF- and caspase-dependent apoptotic signaling cascades via differential upregulation of nuclear PARP-1 and mitochondrial translocation of Bax.

Abstract
Increased expression of the inducible and neuronal isoforms of nitric oxide synthase (NOS), and elevated concentrations of nitric oxide (NO) metabolites, are present within the central nervous system (CNS) following neurotrauma and are implicated in the pathogenesis of the accompanying neurologic deficits. We tested the hypothesis that elevated extracellular concentrations of NO introduced by the donor Spermine NONOate, induce reversible axonal conduction deficits in neurons of the guinea pig spinal cord. The compound action potential (CAP) and compound membrane potential (CMP) of excised ventral cord white matter were recorded before, during, and after bathing the tissue (30 min) in varying concentrations (0.25-3.0 mM) of Spermine NONOate. The principal results were a rapid onset, dose-dependent, reduction in amplitude of the CAP (p < 0.05) accompanied by depolarization of the CMP during NO exposure. These effects were largely reversible on washout, at low concentration of the donor (0.5 mM), but were only partially reversed at higher concentrations. Changes in the electrophysiological properties were not evident when the donor had been a priori depleted of NO. The results extend previous reports that NO induces reversible axonal conduction deficits. They provide new evidence of dissociation of the effects of NO on CAP and CMP during washout, and after prolonged exposure to the donor. They add support to the emerging concept that immune-mediated axonal conduction failure contributes to reversible neurologic deficits following neurotrauma and aid in understanding clinical phenomena such as spinal shock and neurologic recovery.
