Mitochondria Need Their Sleep: Redox, Bioenergetics, and Temperature Regulation of Circadian Rhythms and the Role of Cysteine-Mediated Redox Signaling, Uncoupling Proteins, and Substrate Cycles. Antioxidants (Basel) 2023; 12:antiox12030674. [PMID: 36978924 PMCID: PMC10045244 DOI: 10.3390/antiox12030674] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 02/27/2023] [Accepted: 02/28/2023] [Indexed: 03/12/2023] Open
Abstract
Although circadian biorhythms of mitochondria and cells are highly conserved and crucial for the well-being of complex animals, there is a paucity of studies on the reciprocal interactions between oxidative stress, redox modifications, metabolism, thermoregulation, and other major oscillatory physiological processes. To address this limitation, we hypothesize that circadian/ultradian interaction of the redoxome, bioenergetics, and temperature signaling strongly determine the differential activities of the sleep–wake cycling of mammalians and birds. Posttranslational modifications of proteins by reversible cysteine oxoforms, S-glutathionylation and S-nitrosylation are shown to play a major role in regulating mitochondrial reactive oxygen species production, protein activity, respiration, and metabolomics. Nuclear DNA repair and cellular protein synthesis are maximized during the wake phase, whereas the redoxome is restored and mitochondrial remodeling is maximized during sleep. Hence, our analysis reveals that wakefulness is more protective and restorative to the nucleus (nucleorestorative), whereas sleep is more protective and restorative to mitochondria (mitorestorative). The “redox–bioenergetics–temperature and differential mitochondrial–nuclear regulatory hypothesis” adds to the understanding of mitochondrial respiratory uncoupling, substrate cycling control and hibernation. Similarly, this hypothesis explains how the oscillatory redox–bioenergetics–temperature–regulated sleep–wake states, when perturbed by mitochondrial interactome disturbances, influence the pathogenesis of aging, cancer, spaceflight health effects, sudden infant death syndrome, and diseases of the metabolism and nervous system.

Abstract
Nitroxyl (HNO) is the one-electron reduced and protonated congener of nitric oxide (•NO), owning a distinct chemical profile. Based on real-time detection, we demonstrate that HNO is endogenously formed in Arabidopsis. Senescence and hypoxia induce shifts in the redox balance, triggering HNO decay or formation mediated by non-enzymatic •NO/HNO interconversion with cellular reductants. The stimuli-dependent HNO generation supports or competes with •NO signalling, depending on the local redox environment.

Coumaric acid from M. polymorphum extracts reverses the activated state of hepatic stellate cells (GRX) and inhibits their proliferation by decreasing the p53/p21 pathway. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2022; 396:925-937.

Abstract
Coumaric acid is a phenolic compound found in medicinal plants. Its use has been reported in the treatment of inflammatory diseases, prevention of alterations induced by oxidative stress, as well as acetaminophen-induced hepatotoxicity. Thus, this study evaluated coumaric acid as a potential treatment for liver fibrosis. Cell proliferation was assessed by the trypan blue exclusion technique and the cytotoxicity of coumaric acid was performed using an LDH assay. Mechanisms of cell apoptosis were evaluated by flow cytometry. The expression of genes associated with apoptosis, cell cycle control, and fibrosis was assessed by qPCR. The production of lipid droplets was quantified by oil red staining. The experiments performed showed that the treatment with coumaric acid was able to reduce cell proliferation without causing cell cytotoxicity or apoptosis. Coumaric acid was able to inhibit the expression of cyclin D1 and CDK's (CDK2, CDK4, and CDK6), increasing p53 and p21, which could lead to cell cycle arrest. Treatment with coumaric acid was also able to revert the activated phenotype of GRX cells to their quiescent state. Thus, our results suggest that coumaric acid has a potential therapeutic effect against liver fibrosis.

Cysteine Oxidation Promotes Dimerization/Oligomerization of Circadian Protein Period 2. Biomolecules 2022; 12:biom12070892.

Abstract
The molecular circadian clock is based on a transcriptional/translational feedback loop in which the stability and half-life of circadian proteins is of importance. Cysteine residues of proteins are subject to several redox reactions leading to S-thiolation and disulfide bond formation, altering protein stability and function. In this work, the ability of the circadian protein period 2 (PER2) to undergo oxidation of cysteine thiols was investigated in HEK-293T cells. PER2 includes accessible cysteines susceptible to oxidation by nitroso cysteine (CysNO), altering its stability by decreasing its monomer form and subsequently increasing PER2 homodimers and multimers. These changes were reversed by treatment with 2-mercaptoethanol and partially mimicked by hydrogen peroxide. These results suggest that cysteine oxidation can prompt PER2 homodimer and multimer formation in vitro, likely by S-nitrosation and disulphide bond formation. These kinds of post-translational modifications of PER2 could be part of the redox regulation of the molecular circadian clock.

Abstract
BACKGROUND We previously demonstrated that nitroxyl causes vasodilation, at least in part, by inducing the formation of an intradisulfide bond between C117 and C195 in the high affinity cyclic guanosine monophosphate-binding site of PKGI (cyclic guanosine monophosphate-dependent protein kinase I). The aim of this study was to determine whether nitroxyl donors lower blood pressure via this novel PKGI activation mechanism in vivo. METHODS To determine this, a C195S PKGI knock-in mouse model was generated that ubiquitously and constitutively expresses a mutant kinase resistant to nitroxyl-induced intradisulfide activation. RESULTS Knock-in and wild-type littermates did not differ in appearance, body weight, in PKGI protein expression or blood gas content. Organ weight was similar between genotypes apart from the cecum that was significantly enlarged in knock-in animals. Mean arterial pressure and heart rate monitored in vivo over 24 hours by radio-telemetry revealed neither a significant difference between genotypes at baseline nor during angiotensin II-induced hypertension or sepsis. CXL-1020, a clinically relevant nitroxyl donor, did not lower blood pressure in normotensive animals. In contrast, administering CXL-1020 to hypertensive wild-type mice reduced their blood pressure by 10±4 mm Hg (P=0.0184), whereas the knock-in littermates were unaffected. CONCLUSIONS Oxidation of C195 in PKGI contributes to the antihypertensive effects observed in response to nitroxyl donors, emphasising the potential importance of nitroxyl donors in pathological scenarios when cyclic guanosine monophosphate levels are reduced and insufficient to activate PKGI.

Abstract
Nowadays, destruction of redox homeostasis to induce cancer cell death is an emerging anti-cancer strategy. Here, the authors utilized pH-sensitive acetalated β-cyclodextrin (Ac-β-CD) to efficiently deliver dihydroartemisinin (DHA) for tumor ferroptosis therapy and chemodynamic therapy in a synergistic manner. The Ac-β-CD-DHA based nanoparticles are coated by an iron-containing polyphenol network. In response to the tumor microenvironment, Fe2+ /Fe3+ can consume glutathione (GSH) and trigger the Fenton reaction in the presence of hydrogen peroxide (H2 O2 ), leading to the generation of lethal reactive oxygen species (ROS). Meanwhile, the OO bridge bonds of DHA are also disintegrated to enable ferroptosis of cancer cells. Their results demonstrate that these nanoparticles acted as a ROS generator to break the redox balance of cancer cells, showing an effective anticancer efficacy, which is different from traditional approaches.
