[PMID: 38671853 PMCID: PMC11047447 DOI: 10.3390/antiox13040405] [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: 12/17/2023] [Revised: 02/25/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
Abstract
Myocardial ischemia/reperfusion injury (I/R) and the resulting heart failure is one of the main causes of mortality and morbidity worldwide. Camphene has been shown to have anti-inflammatory and hypolipidemic properties; however, its role in the protection of the heart from ischemia and reperfusion has not been investigated. The cardioprotective role of camphene and the mechanism that mediates its action against I/R injury was evaluated in the present study. A single dose of camphene was administered in adult rats prior to ex vivo I/R induction. Infarct size was measured using 2,3,5-triphenyltetrazolium chloride (TTC) staining and cardiomyocyte injury was assessed by determining the release of the enzyme lactate dehydrogenase (LDH). Camphene pretreatment provided significant protection reducing myocardial infarct size and cell death after I/R. The effect was correlated with the reduction in oxidative stress as evidenced by the determination of protein carbonylation, GSH/GSSG ratio, the increase in mitochondrial content as determined by CS activity, and the modulation of antioxidant defense mechanisms (expression of Nrf2 and target genes and activities of CAT, MnSOD, and GR). Furthermore, ferroptosis was decreased, as demonstrated by downregulation of GPx4 expression and reduction in lipid peroxidation. The results suggest that camphene can protect the heart against I/R injury by maintaining redox homeostasis and can hold therapeutic potential for mitigating the detrimental effects of I/R in the heart.

S-adenosylmethionine induces mitochondrial dysfunction, permeability transition pore opening and redox imbalance in subcellular preparations of rat liver. J Bioenerg Biomembr 2021; 53:525-539. [PMID: 34347214 DOI: 10.1007/s10863-021-09914-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Accepted: 07/17/2021] [Indexed: 01/03/2023]
Abstract
S-adenosylmethionine (AdoMet) predominantly accumulates in tissues and biological fluids of patients affected by liver dysmethylating diseases, particularly glycine N-methyltransferase, S-adenosylhomocysteine hydrolase and adenosine kinase deficiencies, as well as in some hepatic mtDNA depletion syndromes, whose pathogenesis of liver dysfunction is still poorly established. Therefore, in the present work, we investigated the effects of S-adenosylmethionine (AdoMet) on mitochondrial functions and redox homeostasis in rat liver. AdoMet decreased mitochondrial membrane potential and Ca2+ retention capacity, and these effects were fully prevented by cyclosporin A and ADP, indicating mitochondrial permeability transition (mPT) induction. It was also verified that the thiol-alkylating agent NEM prevented AdoMet-induced ΔΨm dissipation, implying a role for thiol oxidation in the mPT pore opening. AdoMet also increased ROS production and provoked protein and lipid oxidation. Furthermore, AdoMet reduced GSH levels and the activities of aconitase and α-ketoglutarate dehydrogenase. Free radical scavengers attenuated AdoMet effects on lipid peroxidation and GSH levels, supporting a role of ROS in these effects. It is therefore presumed that disturbance of mitochondrial functions associated with mPT and redox unbalance may represent relevant pathomechanisms of liver damage provoked by AdoMet in disorders in which this metabolite accumulates.

Free Radical Scavengers Prevent Argininosuccinic Acid-Induced Oxidative Stress in the Brain of Developing Rats: a New Adjuvant Therapy for Argininosuccinate Lyase Deficiency? Mol Neurobiol 2019; 57:1233-1244.

Abstract
Tissue accumulation and high urinary excretion of argininosuccinate (ASA) is the biochemical hallmark of argininosuccinate lyase deficiency (ASLD), a urea cycle disorder mainly characterized by neurologic abnormalities, whose pathogenesis is still unknown. Thus, in the present work, we evaluated the in vitro and in vivo effects of ASA on a large spectrum of oxidative stress parameters in brain of adolescent rats in order to test whether disruption of redox homeostasis could be involved in neurodegeneration of this disorder. ASA provoked in vitro lipid and protein oxidation, decreased reduced glutathione (GSH) concentrations, and increased reactive oxygen species generation in cerebral cortex and striatum. Furthermore, these effects were totally prevented or attenuated by the antioxidants melatonin and GSH. Similar results were obtained by intrastriatal administration of ASA, in addition to increased reactive nitrogen species generation and decreased activities of superoxide dismutase, glutathione peroxidase, and glutathione S-transferase. It was also observed that melatonin and N-acetylcysteine prevented most of ASA-induced in vivo pro-oxidant effects in striatum. Taken together, these data indicate that disturbance of redox homeostasis induced at least in part by high brain ASA concentrations per se may potentially represent an important pathomechanism of neurodegeneration in patients with ASLD and that therapeutic trials with appropriate antioxidants may be an adjuvant treatment for these patients.

Abstract
Preeclampsia (PE) is a leading cause of pregnancy complications, affecting 3-7% of pregnant women worldwide. The pathophysiology of preeclampsia involves a redox imbalance, oxidative stress and a reduced nitric oxide (NO) bioavailability. The molecular and cellular mechanisms leading to the dysfunction of the placental endothelial NO synthase (eNOS) are not clarified. This study was designed to investigate whether aldehydes generated by lipid peroxidation products (LPP), may contribute to placental eNOS dysfunction in PE. The analysis of placentas from PE-affected patients and normal pregnancies, showed a significant increase in protein carbonyl content, indicative of oxidative stress-induced protein modification, as shown by the accumulation of acrolein, 4-hydroxynonenal (HNE), and 4-oxo-2(E)-nonenal (ONE) adducts in PE placentas. In contrast, the levels of these LPP-adducts were low in placentas from normal pregnancies. Immunofluorescence and confocal experiments pointed out a colocalization of eNOS with ONE-Lys adducts, whereas eNOS was not modified in normal placentas. LC-MS/MS analysis of recombinant eNOS preincubated with ONE, allowed to identify several ONE-modified Lys-containing peptides, confirming that eNOS may undergo post-translational modification by LPP. The preincubation of HTR-8/SVneo human trophoblasts (HTR8) with ONE, resulted in ONE-Lys modification of eNOS and a reduced generation of NO. ONE inhibited the migration of HTR8 trophoblasts in the wound closure model, and this was partly restored by the NO donor, NOC-18, which confirmed the important role of NO in the invasive potential of trophoblasts. In conclusion, placental eNOS is modified by ONE in PE placentas, which emphasizes the sensitivity of this protein to oxidative stress in the disturbed redox environment of preeclamptic pregnancies.

Abstract
Proteomics and metabolomics are emerging and powerful tools to unravel the complex molecular mechanisms regulating reproduction in male fish. So far, numerous proteins and metabolites have been identified that provide us with valuable information to conduct a comprehensive analysis on seminal plasma and spermatozoa components and their functions. These analyses have allowed a better understanding of the blood-testis barrier functions, the molecular mechanisms underlying spermatogenesis, spermatozoa maturation, motility signaling, and competition as well as the mechanism of cryodamage to sperm structure and functions. To extend, proteins that undergo posttranslational modification, such as phosphorylation and oxidation in response to spermatozoa motility activation and cryopreservation, respectively, have been identified. Proteomic studies resulted in identification of potential proteins that can be used as biomarkers for sperm quality and freezability to enable the control of artificial reproduction, and to improve methods for long-term preservation (cryopreservation) of sperm. The different proteins expressed in the spermatozoa of neomales and normal males can also provide new insights into development of methods for separating X and Y fish sperm, and changes in the protein profiles in haploid and diploid spermatozoa will provide new perspectives to better understand the mechanism of male polyploidy. Overall, the knowledge gained by proteomic and metabolomic studies is important from basic to applied sciences for the development and/or optimisation of techniques in controlled fish reproduction.

Abstract
BACKGROUND Major depressive disorder (MDD) affects many people in the world. However, around 40% of patients do not respond to any pharmacological drugs. An alternative is to use a combination of different pharmacological groups or the combination of a classical antidepressant with a substance that can potentiate its effect. Thus, this study aimed to investigate the synergistic interactions between different antidepressants, including fluoxetine, quetiapine and lamotrigine in combination with ketamine, a N-methyl-d-aspartate (NMDA) receptor antagonist. METHODS Wistar rats were acutely treated with fluoxetine (1.25mg/kg), quetiapine (5mg/kg), and lamotrigine (5.0mg/kg) alone or in combination with ketamine (5.0mg/kg), and then subjected to behavioral tests. In addition, oxidative damage and antioxidant capacity were assessed in the rat brain, and pro-inflammatory cytokines levels were evaluated in the serum. RESULTS It was observed a synergistic effect of ketamine in combination with fluoxetine on the immobility time in the forced swimming test, indicating an antidepressant effect. Other antidepressant did not show effects when administrated alone or joint to ketamine. The combination of ketamine with other antidepressants, particularly quetiapine, in some brain regions induced an increase in damage to lipids and proteins. However, the combination of ketamine with fluoxetine increased the antioxidant activity of superoxide dismutase, and decreased oxidative damage, thus suggesting a neuroprotective effect of the combination of these drugs. The combination of ketamine with fluoxetine or lamotrigine reduced pro-inflammatory cytokines levels. CONCLUSION In conclusion, ketamine induced antioxidant or pro-antioxidant effects dependent of antidepressant classes or brain area.
