[PMID: 38508405 DOI: 10.1016/j.freeradbiomed.2024.03.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 02/10/2024] [Accepted: 03/13/2024] [Indexed: 03/22/2024]
Abstract
The objective of the current review is to summarize the current state of optical methods in redox biology. It consists of two parts, the first is dedicated to genetically encoded fluorescent indicators and the second to Raman spectroscopy. In the first part, we provide a detailed classification of the currently available redox biosensors based on their target analytes. We thoroughly discuss the main architecture types of these proteins, the underlying engineering strategies for their development, the biochemical properties of existing tools and their advantages and disadvantages from a practical point of view. Particular attention is paid to fluorescence lifetime imaging microscopy as a possible readout technique, since it is less prone to certain artifacts than traditional intensiometric measurements. In the second part, the characteristic Raman peaks of the most important redox intermediates are listed, and examples of how this knowledge can be implemented in biological studies are given. This part covers such fields as estimation of the redox states and concentrations of Fe-S clusters, cytochromes, other heme-containing proteins, oxidative derivatives of thiols, lipids, and nucleotides. Finally, we touch on the issue of multiparameter imaging, in which biosensors are combined with other visualization methods for simultaneous assessment of several cellular parameters.

Abstract
The functions, purposes, and roles of metallothioneins have been the subject of speculations since the discovery of the protein over 60 years ago. This article guides through the history of investigations and resolves multiple contentions by providing new interpretations of the structure-stability-function relationship. It challenges the dogma that the biologically relevant structure of the mammalian proteins is only the one determined by X-ray diffraction and NMR spectroscopy. The terms metallothionein and thionein are ambiguous and insufficient to understand biological function. The proteins need to be seen in their biological context, which limits and defines the chemistry possible. They exist in multiple forms with different degrees of metalation and types of metal ions. The homoleptic thiolate coordination of mammalian metallothioneins is important for their molecular mechanism. It endows the proteins with redox activity and a specific pH dependence of their metal affinities. The proteins, therefore, also exist in different redox states of the sulfur donor ligands. Their coordination dynamics allows a vast conformational landscape for interactions with other proteins and ligands. Many fundamental signal transduction pathways regulate the expression of the dozen of human metallothionein genes. Recent advances in understanding the control of cellular zinc and copper homeostasis are the foundation for suggesting that mammalian metallothioneins provide a highly dynamic, regulated, and uniquely biological metal buffer to control the availability, fluctuations, and signaling transients of the most competitive Zn(II) and Cu(I) ions in cellular space and time.

Abstract
S-glutathionylation and S-nitrosylation are reversible post-translational modifications on the cysteine thiol groups of proteins, which occur in cells under physiological conditions and oxidative/nitrosative stress both spontaneously and enzymatically. They are important for the regulation of the functional activity of proteins and intracellular processes. Connecting link and “switch” functions between S-glutathionylation and S-nitrosylation may be performed by GSNO, the generation of which depends on the GSH content, the GSH/GSSG ratio, and the cellular redox state. An important role in the regulation of these processes is played by Trx family enzymes (Trx, Grx, PDI), the activity of which is determined by the cellular redox status and depends on the GSH/GSSG ratio. In this review, we analyze data concerning the role of GSH/GSSG in the modulation of S-glutathionylation and S-nitrosylation and their relationship for the maintenance of cell viability.

Abstract
This study describes the theoretical basis and the methods for the facile synthesis and characterization of four fluorogenic probes, N-amido-O-aminobenzoyl-S-nitrosoglutathione (AOASNOG), N-thioamido-fluoresceinyl-S-nitroso-glutathione (TFSNOG), N,N-di(thioamido-fluoresceinyl)-cystine (DTFCys2) and N,N-di(thioamido-fluoresceinyl)-homocystine (DTFHCys2). In addition, the study describes the methodology for the application of these reagents for measuring and imaging of free thiols on cell surfaces as well as their use as pseudo substrates for the thiol reductase and S-nitrosothioldenitrosylase activities of protein disulfide isomerase (PDI) and S-nitrosothiol reductase activity of S-nitrosoglutathione reductase (GSNOR) in vitro and on live cells in culture.

Abstract
UNLABELLED Over the last decades a broad collection of sophisticated fluorescent protein-based probes was engineered with the aim to specifically monitor nitric oxide (NO), one of the most important signaling molecules in biology. Here we report and discuss the characteristics and fields of applications of currently available genetically encoded fluorescent sensors for the detection of NO and its metabolites in different cell types. LONG ABSTRACT Because of its radical nature and short half-life, real-time imaging of NO on the level of single cells is challenging. Herein we review state-of-the-art genetically encoded fluorescent sensors for NO and its byproducts such as peroxynitrite, nitrite and nitrate. Such probes enable the real-time visualization of NO signals directly or indirectly on the level of single cells and cellular organelles and, hence, extend our understanding of the spatiotemporal dynamics of NO formation, diffusion and degradation. Here, we discuss the significance of NO detection in individual cells and on subcellular level with genetic biosensors. Currently available genetically encoded fluorescent probes for NO and nitrogen species are critically discussed in order to provide insights in the functionality and applicability of these promising tools. As an outlook we provide ideas for novel approaches for the design and application of improved NO probes and fluorescence imaging protocols.

Abstract
Essentials Nitric oxide synthesis controls protein disulfide isomerase (PDI) function. Nitric oxide (NO) modulation of PDI controls endothelial thrombogenicity. S-nitrosylated PDI inhibits platelet function and thrombosis. Nitric oxide maintains vascular quiescence in part through inhibition of PDI. SUMMARY: Background Protein disulfide isomerase (PDI) plays an essential role in thrombus formation, and PDI inhibition is being evaluated clinically as a novel anticoagulant strategy. However, little is known about the regulation of PDI in the vasculature. Thiols within the catalytic motif of PDI are essential for its role in thrombosis. These same thiols bind nitric oxide (NO), which is a potent regulator of vessel function. To determine whether regulation of PDI represents a mechanism by which NO controls vascular quiescence, we evaluated the effect of NO on PDI function in endothelial cells and platelets, and thrombus formation in vivo. Aim To assess the effect of S-nitrosylation on the regulation of PDI and other thiol isomerases in the vasculature. Methods and results The role of endogenous NO in PDI activity was evaluated by incubating endothelium with an NO scavenger, which resulted in exposure of free thiols, increased thiol isomerase activity, and enhanced thrombin generation on the cell membrane. Conversely, exposure of endothelium to NO+ carriers or elevation of endogenous NO levels by induction of NO synthesis resulted in S-nitrosylation of PDI and decreased surface thiol reductase activity. S-nitrosylation of platelet PDI inhibited its reductase activity, and S-nitrosylated PDI interfered with platelet aggregation, α-granule release, and thrombin generation on platelets. S-nitrosylated PDI also blocked laser-induced thrombus formation when infused into mice. S-nitrosylated ERp5 and ERp57 were found to have similar inhibitory activity. Conclusions These studies identify NO as a critical regulator of vascular PDI, and show that regulation of PDI function is an important mechanism by which NO maintains vascular quiescence.

Abstract
Thiol isomerases are multifunctional enzymes that influence protein structure via their oxidoreductase, isomerase, and chaperone activities. These enzymes localize at high concentrations in the endoplasmic reticulum of all eukaryotic cells where they serve an essential function in folding nascent proteins. However, thiol isomerases can escape endoplasmic retention and be secreted and localized on plasma membranes. Several thiol isomerases including protein disulfide isomerase, ERp57, and ERp5 are secreted by and localize to the membranes of platelets and endothelial cells. These vascular thiol isomerases are released following vessel injury and participate in thrombus formation. Although most of the activities of vascular thiol isomerases that contribute to thrombus formation are yet to be defined at the molecular level, allosteric disulfide bonds that are modified by thiol isomerases have been described in substrates such as αIIbβ3, αvβ3, GPIbα, tissue factor, and thrombospondin. Vascular thiol isomerases also act as redox sensors. They respond to the local redox environment and influence S-nitrosylation of surface proteins on platelets and endothelial cells. Despite our rudimentary understanding of the mechanisms by which thiol isomerases control vascular function, the clinical utility of targeting them in thrombotic disorders is already being explored in clinical trials.

Abstract
A three step protocol for protein S-nitrosothiol conversion to fluorescent mixed disulfides with purified proteins, referred to as the thiosulfonate switch, is explored which involves: (1) thiol blocking at pH 4.0 using S-phenylsulfonylcysteine (SPSC); (2) trapping of protein S-nitrosothiols as their S-phenylsulfonylcysteines employing sodium benzenesulfinate; and (3) tagging the protein thiosulfonate with a fluorescent rhodamine based probe bearing a reactive thiol (Rhod-SH), which forms a mixed disulfide between the probe and the formerly S-nitrosated cysteine residue. S-Nitrosated bovine serum albumin and the S-nitrosated C-terminally truncated form of AdhR-SH (alcohol dehydrogenase regulator) designated as AdhR*-SNO were selectively labelled by the thiosulfonate switch both individually and in protein mixtures containing free thiols. This protocol features the facile reaction of thiols with S-phenylsulfonylcysteines forming mixed disulfides at mild acidic pH (pH = 4.0) in both the initial blocking step as well as in the conversion of protein-S-sulfonylcysteines to form stable fluorescent disulfides. Labelling was monitored by TOF-MS and gel electrophoresis. Proteolysis and peptide analysis of the resulting digest identified the cysteine residues containing mixed disulfides bearing the fluorescent probe, Rhod-SH.

Abstract
Protein disulfide isomerase (PDI), ERp5, and ERp57, among perhaps other thiol isomerases, are important for the initiation of thrombus formation. Using the laser injury thrombosis model in mice to induce in vivo arterial thrombus formation, it was shown that thrombus formation is associated with PDI secretion by platelets, that inhibition of PDI blocked platelet thrombus formation and fibrin generation, and that endothelial cell activation leads to PDI secretion. Similar results using this and other thrombosis models in mice have demonstrated the importance of ERp5 and ERp57 in the initiation of thrombus formation. The integrins, αIIbβ3 and αVβ3, play a key role in this process and interact directly with PDI, ERp5, and ERp57. The mechanism by which thiol isomerases participate in thrombus generation is being evaluated using trapping mutant forms to identify substrates of thiol isomerases that participate in the network pathways linking thiol isomerases, platelet receptor activation, and fibrin generation. PDI as an antithrombotic target is being explored using isoquercetin and quercetin 3-rutinoside, inhibitors of PDI identified by high throughput screening. Regulation of thiol isomerase expression, analysis of the storage, and secretion of thiol isomerases and determination of the electron transfer pathway are key issues to understanding this newly discovered mechanism of regulation of the initiation of thrombus formation.

Abstract
AIMS The lack of understanding of the biology of bone cancer metastasis has limited the development of effective treatment strategies. The aim of this study was to characterize tumor cell adhesion molecules and determine active tumor cell interactions with human bone marrow endothelial (BME) cells using atomic force microscopy. MATERIALS & METHODS A single prostate (PC3) cancer cell was coupled (concanavalin A) to the atomic force microscopy cantilever then placed in contact with BME cells for cell force spectroscopy measurements. RESULTS & DISCUSSION Strong adhesive interactions between PC3 and BME cells were significantly (p < 0.05) reduced by anti-ICAM-1, anti-β1 and anti-P-selectin, but not anti-VCAM-1. The combined blocking antibodies or the therapeutic agent zoledronic acid significantly (p < 0.005) reduced the adhesive interactions by 65 and 63%, respectively, which was confirmed using a functional in vitro assay. CONCLUSION Atomic force microscopy provides a highly sensitive screening assay to determine and quantify nanoscale adhesion events between different cell types important in the metastatic cascade.

Abstract
S-nitrosoglutathione (GSNO) at low concentration inhibits platelet aggregation without causing vasodilation, suggesting platelet-selective nitric oxide delivery. The mechanism of this selectivity is unknown, but may involve cell surface thiol isomerases, in particular protein disulphide isomerase (csPDI) (EC 5.3.4.1). We have now compared csPDI expression and activity on platelets, endothelial cells and vascular smooth muscle cells, and the dependence on thiol reductase activity of these cell types for NO uptake from GSNO. csPDI expression was measured by flow cytometry and its reductase activity using the pseudosubstrate dieosin glutathione disulphide. This activity assay was adapted and validated for 96-well plate format. Flow cytometry revealed csPDI on all three cell types, but percentage positivity of expression was higher on platelets than on vascular cells. Consistent with this, thiol isomerase-related reductase activity was higher on platelets (P < 0.01), and cellular activation (with either phorbol myristate acetate or ionomycin) increased csPDI activity on both platelets and smooth muscle cells, but not on endothelium. Intracellular NO delivery from GSNO was greater in platelets than in vascular cells (P < 0.002), and was more sensitive to thiol isomerase inhibition using phenylarsine oxide (P < 0.05). Increased surface thiol isomerase activity on platelets, compared with cells of the vascular wall, may explain the platelet-selective actions of GSNO and help define its antithrombotic potential.

Abstract
Protein disulfide isomerase (PDI) is a promiscuous protein with multifunctional properties. PDI mediates proper protein folding by oxidation or isomerization and disrupts disulfide bonds by reduction. The entry of HIV-1 into cells is facilitated by the PDI-catalyzed reductive cleavage of disulfide bonds in gp120. PDI is regarded as a potential drug target because of its reduction activity. We screened a chemical library of natural products for PDI-specific inhibitors in a high-throughput fashion and identified the natural compound juniferdin as the most potent inhibitor of PDI. Derivatives of juniferdin were synthesized, with compound 13 showing inhibitory activities comparable to those of juniferdin but reduced cytotoxicity. Both juniferdin and compound 13 inhibited PDI reductase activity in a dose-dependent manner, with IC(50) values of 156 and 167 nM, respectively. Our results also indicated that juniferdin and compound 13 exert their inhibitory activities specifically on PDI but do not significantly inhibit homologues of this protein family. Moreover, we found that both compounds can inhibit PDI-mediated reduction of HIV-1 envelope glycoprotein gp120.

Abstract
S-nitrosoalbumin (SNO-Alb) has been shown to be an efficacious cytoprotective molecule in acute lung injury, as well as ischemia-reperfusion injury in heart and skeletal muscle. Nonetheless, limited information is available on the cellular mechanism of such protection. Accordingly, we investigated the protective effects of SNO-Alb [ and its denitrosated congener, reduced albumin (SH-Alb) ] on tert-butyl hydroperoxide (tBH)-mediated cytotoxicity in cultured rat pulmonary microvascular endothelial cells (RPMEC), as well as hydrogen sulfide (H(2)S)-mediated cytotoxicity in rat pulmonary artery smooth muscle cells (RPASMC). We noted that tBH caused a concentration-dependent necrosis in RPMEC, and pretreatment of RPMEC with SNO-Alb dose-dependently decreased the sensitivity of these cells to tBH. A component of SNO-Alb cytoprotection was sensitive to N(G)-nitro-L-arginine methyl ester and was associated with activation of endothelial nitric oxide synthase (eNOS), phenomena that could be reproduced with pretreatment with SH-Alb. Exogenous H(2)S caused concentration-dependent apoptosis in RPASMC due to activation of ERK1/2 and p38, as well as downregulation of Bcl-2. Pretreatment with SNO-Alb reduced H(2)S-mediated apoptosis in a concentration-dependent manner that was associated with SNO-Alb-mediated inhibition of activation of ERK1/2 and p38. Pretreatment with SNO-Alb reduced toxicity of 1 mM sodium hydrosulfide in an N(G)-nitro-L-arginine methyl ester-sensitive fashion in RPASMC that expressed gp60 and neuronal NOS and was capable of transporting fluorescently labeled SH-Alb. Therefore, SNO-Alb is cytoprotective against models of oxidant-induced necrosis (tBH) and inhibitors of cellular respiration and apoptosis (H(2)S) in both pulmonary endothelium and smooth muscle, respectively, and a component of such protection can be attributed to a SH-Alb-mediated activation of constitutive NOS.

Abstract
We have shown that zinc-thiolate moieties of the metal binding protein metallothionein (MT) are critical targets for nitric oxide (NO) with resultant increases in intracellular labile zinc. Such an NO-MT-Zn signaling pathway appears to participate in important cardiovascular functions associated with biosynthesis of NO including hypoxic vasoconstriction in the lung. Although downstream effector signaling molecules and critical contractile targets remain unclear, current investigations reveal a contributory role for zinc dependent protein kinases and cytoskeletal proteins in mediating hypoxic induced constriction of pulmonary endothelial cells.

Abstract
Although the insertion of heme into proteins enables their function in bioenergetics, metabolism, and signaling, the mechanisms and regulation of this process are not fully understood. We developed a means to study cellular heme insertion into apo-protein targets over a 3-h period and then investigated how nitric oxide (NO) released from a chemical donor (NOC-18) might influence heme (protoporphyrin IX) insertion into seven targets that present a range of protein structures, heme ligation states, and functions (three NO synthases, two cytochrome P450's, catalase, and hemoglobin). NO blocked cellular heme insertion into all seven apo-protein targets. The inhibition occurred at relatively low (nM/min) fluxes of NO, was reversible, and did not involve changes in intracellular heme levels, activation of guanylate cyclase, or inhibition of mitochondrial ATP production. These aspects and the range of protein targets suggest that NO can act as a global inhibitor of heme insertion, possibly by inhibiting a common step in the process.
