Abstract
Enhancing the sensitivity and selectivity of chemiluminescence (CL) sensors for detecting chemical species in complex samples poses a significant challenge in nanoparticle surface engineering. Graphitic carbon nitride (CN) shows promise but suffers from weak CL intensity and unknown luminescence mechanisms. In this study, we propose a nitrogen defect strategy to enhance the CL efficiency of europium-functionalized graphitic carbon nitride (Eu-CNNPs). By controlling the dosage of the europium modification, we can adjust the nitrogen defect content to reduce the energy gap and improve the CL performance. Remarkably, Eu-CNNPs with rich nitrogen defects exhibit strong chemiluminescence emission specifically for singlet oxygen (1O2) without responding to other reactive oxygen species (ROS). Building upon this finding, we developed a direct, selective, and sensitive CL sensing platform for 1O2 in PM2.5 and monitored 1O2 production in photosensitizers without interference from metal ions. Through extensive experiments, we attribute the 1O2-driven CL response to the presence of abundant nitrogen defects in the CN material, accelerating electron transfer and yielding a high generation of 1O2. Furthermore, chemiluminescence resonance energy transfer (CRET) between (1O2)2* (1O2 dimeric aggregate) and Eu-CNNPs contributes to strong CL emission. This work provides insights into enhancing the CL performance of CN and offers new possibilities for advancing the practical analysis of nanomaterials using the intriguing mechanism of nitrogen defects.

Abstract
Reactive oxygen species (ROS) play important roles in organisms and are closely related to various physiological and pathological processes. Due to the short lifetime and easy transformation of ROS, the determination of ROS content in biosystem has always been a challenging task. Chemiluminescence (CL) analysis has been widely used in the detection of ROS due to its advantages of high sensitivity, good selectivity and no background signal, among which nanomaterial-related CL probes are rapidly developing. In this review, the roles of nanomaterials in CL systems are summarized, mainly including their roles as catalysts, emitters, and carriers. The nanomaterial-based CL probes for biosensing and bioimaging of ROS developed in the past five years are reviewed. We expect that this review will provide guidance for the design and development of nanomaterial-based CL probes and facilitate the wider application of CL analysis in ROS sensing and imaging in biological systems.

Abstract
Characterizing the transient ultratrace light-independent intracellular singlet oxygen (1O2), which plays a vital role in multiple biological processes in living organisms, brings about tremendous help for understanding the nature of 1O2-mediated or related bioevents. Nevertheless, an approach to detect the light-independent intracellular 1O2 is hard to find. Herein, we developed a chemiluminescent nanosensor by compacting a great number of TPE-N(Ph)-DBT-PH molecules in one nanostructure via autoaggregation. Taking advantage of the aggregation-induced emission property, this TPE-N(Ph)-DBT-PH nanosensor is highly fluorescent and promises a bright red-light CL and the convenience of mapping in vivo sensor distribution. Experiments demonstrate the nanosensor's unprecedented selectivity toward 1O2 against other reactive oxygen species. The 3.7 nmol L-1 limit of detection renders this nanosensor with the best-known sensitivity of 1O2 chemical sensors. Meanwhile, fluorescence confocal microscope imaging results suggest that our nanosensor simultaneously targets mitochondria and lysosomes in RAW 264.7 cells via the energy-dependent endocytosis pathway, thereby implying an attractive potential for the detection of intracellular 1O2. Such a potential is demonstrated by detecting 1O2 in RAW 264.7 cells during a lipopolysaccharide and phorbol myristate acetate stimulated respiration burst. This study represents the first approach to detect light-independent intracellular 1O2 during cell bioregulation. Thus, our nanosensor provides an effective tool for investigating the 1O2-related bioprocesses and pathological processes.

Abstract
Singlet oxygen (1O2) plays a vital role in metabolism. However, because of its extremely high reactivity and short-lived state, the in vivo detection of 1O2 is challenging. To address this issue, for the first time, we herein constructed a near-infrared (NIR) chemiluminescent probe (CL-SO) by caging the precursor of phenoxy-dioxetane scaffolds and a dicyanomethylchromone acceptor for selective 1O2 detection. This probe can detect 1O2 in vitro with a tremendous turn-on chemiluminescence signal in the NIR region (700 nm) and image intracellular 1O2 produced by the photosensitizer during the simulated action of photodynamic therapy (PDT). Notably, 1O2 level changes in the abdominal cavity and tumor of the various mice model under different stimulations and PDT action were effectively monitored by CL-SO, providing a novel chemiluminescence imaging platform to explore 1O2 generation in PDT-associated applications.

Abstract
Singlet oxygen (1O2) plays significant physiological and pathological functions, especially in causing photodynamic stress in vivo. However, specific 1O2 monitoring is an immense challenge, owing to its short half-lives and high oxidizing ability. To address this, we engineered three photostable two-photon fluorescence probe NBs for highly efficient 1O2 monitoring based on bioinspired novel tryptophan derivatives, among which NB-MOT was the best one comprehensively. Upon being cracked with 1O2, NB-MOT rapidly (within 5 s) demonstrated a remarkable enhancement in fluorescence intensity (∼180 fold) and lifetime (∼18 fold). Taking these advantages into account, NB-MOT was applied to evaluate exogenous and endogenous 1O2 in diverse biosystems. We successfully tracked the intracellular 1O2 level during photodynamic therapy, and for the first time achieved 1O2 mapping in live cells with dual-mode imaging as well as revealed ciprofloxacin-induced photodynamic stress in mice. NB-MOT was thus believed to be of instructive significance for studying the 1O2-mediated stress in wider biological milieus.

Abstract
Mitogen- and stress-activated protein kinase (MSK) is a recently identified nuclear cAMP-regulated enhancer B (CREB) and histone H3 kinase that responds to both mitogen- and stress-activated protein kinases. This study was designed to investigate the protective effect of MSK on the rats with focal ischemia-reperfusion injury. The rat model was established by inserting thread into the middle cerebral artery. The protein expression was measured by immunoblotting. The localization of MSK was measured by immunofluorescence assay. Highly-differentiated pheochromocytoma 12 (PC12) is used as a sympathetic neuron-like cell line and treated with glutamate to induce neurotoxicity. MSK was knocked down and overexpressed by siRNA and MSK over-expressing vector, respectively. The cell viability was measured by cell counting kit (CCK-8) assay. The coronal sections were isolated and stained with 2, 3, 5-triphenyltetrazolium chloride (TTC) to determine infarct volume. Finally, astrocytes were separated from cerebral cortexes of normal rats to analyze the effects of MSK on inflammatory response. In the rats with focal ischemia-reperfusion injury, the expression of MSK was reduced, reaching the lowest level at 3 d after ischemia-reperfusion, and then recovered gradually. MSK was found mainly localized in neurons and astrocytes. The expression levels of caspase-3, caspase-8, caspase-9, and INOS showed the opposite trend with respect to MSK. Further analysis showed that overexpression of MSK exerted a protective effect on glutamate-induced neurotoxicity through inhibiting apoptosis of PC12 cells, as well as decreased the infarct size in rat with focal ischemia-reperfusion injury. On the contrary, knockdown of MSK showed opposite results. Finally, MSK suppressed LPS-induced inflammatory response by decreasing the expression of inducible nitric oxide synthase (INOS) and increasing the expression of interleukin-10 (IL-10) in astrocytes from cerebral cortexes of normal rats. In conclusion, MSK exerted a protective effect on rat with focal ischemia-reperfusion injury through its anti-apoptotic effect on neurons and anti-inflammatory effect on astrocytes.

Abstract
A europium(III) DOTA-tetraamide complex was designed as a MRI sensor of singlet oxygen ((1)O2). The water soluble, thermodynamically stable complex reacts rapidly with (1)O2 to form an endoperoxide derivative that results in an ∼3 ppm shift in the position of the Eu(III)-bound water chemical exchange saturation transfer (CEST) peak. The potential of using this probe to detect accumulation of the endoperoxide derivative in biological media by ratiometric CEST imaging was demonstrated.

Abstract
Reactive oxygen species, as singlet oxygen ((1)O(2)) and hydrogen peroxide, are continuously generated by aerobic organisms, and react actively with biomolecules. At excessive amounts, (1)O(2) induces oxidative stress and shows carcinogenic and toxic effects due to oxidation of lipids, proteins and nucleic acids. Singlet oxygen is able to react with DNA molecule and may induce G to T transversions due to 8-oxodG generation. The nucleotide excision repair, base excision repair and mismatch repair have been implicated in the correction of DNA lesions induced by (1)O(2) both in prokaryotic and in eukaryotic cells. (1)O(2) is also able to induce the expression of genes involved with the cellular responses to oxidative stress, such as NF-κB, c-fos and c-jun, and genes involved with tissue damage and inflammation, as ICAM-1, interleukins 1 and 6. The studies outlined in this review reinforce the idea that (1)O(2) is one of the more dangerous reactive oxygen species to the cells, and deserves our attention.

Abstract
Light-driven electron and energy transfer involving non-DNA skin chromophores as endogenous photosensitizers induces oxidative stress in UVA-exposed human skin, a process relevant to photoaging and photocarcinogenesis. Malondialdehyde is an electrophilic dicarbonyl-species derived from membrane lipid peroxidation. Here, we present experimental evidence suggesting that the malondialdehyde-derived protein epitope dihydropyridine (DHP)-lysine is a potent endogenous UVA-photosensitizer of human skin cells. Immunohistochemical analysis revealed the abundant occurrence of malondialdehyde-derived and DHP-lysine epitopes in human skin. Using the chemically protected dihydropyridine-derivative (2S)-Boc-2-amino-6-(3,5-diformyl-4-methyl-4H-pyridin-1-yl)-hexanoic acid-t-butylester as a model of peptide-bound DHP-lysine, photodynamic inhibition of proliferation and induction of cell death were observed in human skin Hs27 fibroblasts as well as primary and HaCaT keratinocytes exposed to the combined action of UVA and DHP-lysine. DHP-lysine photosensitization induced intracellular oxidative stress, p38 MAPkinase activation, and upregulation of heme oxygenase-1 expression. Consistent with UVA-driven ROS formation from DHP-lysine, formation of superoxide, hydrogen peroxide, and singlet oxygen was detected in chemical assays, but little protection was achieved using SOD or catalase during cellular photosensitization. In contrast, inclusion of NaN(3) completely abolished DHP-photosensitization. Taken together, these data demonstrate photodynamic activity of DHP-lysine and support the hypothesis that malondialdehyde-derived protein-epitopes may function as endogenous sensitizers of UVA-induced oxidative stress in human skin.

Abstract
Heme oxygenase-1 (HO-1) is a key enzyme in the cellular response to tissue injury and oxidative stress. HO-1 enzymatic activity results in the formation of the cytoprotective metabolites CO and biliverdin. In the skin, HO-1 is strongly induced after long wave ultraviolet radiation (UVA-1). Here we show that UVA-1 irradiation generates oxidized phospholipids derived from 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (PAPC) that mediate the expression of HO-1 in skin cells. Using EO6 antibodies that recognize oxidized phospholipids, we show that UVA-1 irradiation of dermal fibroblasts generates oxidation-specific epitopes. Irradiation of arachidonate-containing phospholipids with UVA-1 led to formation of defined lipid oxidation products including epoxyisoprostane-phosphatidylcholine that induced HO-1 expression in dermal fibroblasts, in keratinocytes, and in a three-dimensional epidermal equivalent model. In addition, we demonstrate that the oxidation of PAPC by UVA-1 is a singlet oxygen-dependent mechanism. Together, we present a novel mechanism of UVA-1-induced HO-1 expression that is mediated by the generation of biologically active phospholipid oxidation products. Because UVA-1 irradiation is a mainstay treatment of several inflammatory skin diseases, structural identification of UVA-1-generated biomolecules with HO-1-inducing capacity should lead to the development of drugs that could substitute for irradiation.

Abstract
Receptor tyrosine kinases such as the epidermal growth factor receptor (EGFR) have been proposed to be activated in cells exposed to ultraviolet A (UVA) radiation (320-400 nm) and to be involved in photocarcinogenesis. Singlet oxygen and hydrogen peroxide are being discussed as mediators of the activation of signal transduction pathways by UVA. It is demonstrated here that EGFR is not activated in cells exposed to UVA in the absence of extracellular photosensitizers. Rather, UVA was capable of activating the EGFR and the related ErbB2 receptor tyrosine kinase in HeLa cells and human keratinocytes only under conditions that allowed for the extracellular photochemical generation of H(2)O(2), such as when cells were covered with cell culture medium during exposure to UVA. Pretreatment of cells with vanadate was required for UVA-induced EGFR activation, pointing to the involvement of protein tyrosine phosphatases. Unlike H(2)O(2), photochemically generated singlet oxygen did not activate EGFR but instead impaired the activation of EGFR by its ligand, EGF. In summary, extracellularly generated H(2)O(2) mediates UVA-induced activation of the EGFR and of ErbB2, whereas intracellular generation of reactive oxygen species upon exposure of cells to UVA is not sufficient for activation of the receptor.

Abstract
A new tetrathiafulvalene-anthracene dyad 1 with two "tetraethylene glycol" units was synthesized and characterized. Strong chemiluminescence was observed upon reaction of dyad 1 with singlet oxygen (1O2), and this reaction shows fairly good selectivity toward 1O2 over other reactive oxygen species. Due to the introduction of two hydrophilic "tetraethylene glycol" units, the detection of 1O2 with dyad 1 can be performed in alcohol/water solution, which is relatively a mild medium when compared with water/tetrahydrofuran solution required by other tetrathiafulvalene-anthracene dyads. Dyad 1 may have a wider use for detection of 1O2 in biological systems.

Abstract
Photocarcinogenesis and photoaging are established consequences of chronic exposure of human skin to solar irradiation. Accumulating evidence supports a causative involvement of UVA irradiation in skin photo-damage. UVA photodamage has been attributed to photosensitization by endogenous skin chromophores leading to the formation of reactive oxygen species and organic free radicals as key mediators of cellular photooxidative stress. In this study, 3-hydroxypyridine derivatives contained in human skin have been identified as a novel class of potential endogenous photosensitizers. A structure-activity relationship study of skin cell photosensitization by endogenous pyridinium derivatives (pyridinoline, desmosine, pyridoxine, pyridoxamine, pyridoxal, pyridoxal-5'-phosphate) and various synthetic hydroxypyridine isomers identified 3-hydroxypyridine and N-alkyl-3-hydroxypyridinium cation as minimum phototoxic chromophores sufficient to effect skin cell sensitization toward UVB and UVA, respectively. Photosensitization of cultured human skin keratinocytes (HaCaT) and fibroblasts (CF3) by endogenous and synthetic 3-hydroxypyridine derivatives led to a dose-dependent inhibition of proliferation, cell cycle arrest in G2/M, and induction of apoptosis, all of which were reversible by thiol antioxidant intervention. Enhancement of UVA-induced intracellular peroxide formation and p38 mitogen-activated protein kinase-dependent stress signaling suggest a photooxidative mechanism of skin cell photosensitization by 3-hydroxypyridine derivatives. 3-hydroxypyridine derivatives were potent photosensitizers of macromolecular damage, effecting protein (RNase A) photocross-linking and peptide (melittin) photooxidation with incorporation of molecular oxygen. Based on these results, we conclude that 3-hydroxypyridine derivatives comprising a wide range of skin biomolecules, such as enzymatic collagen cross-links, B6 vitamers, and probably advanced glycation end products in chronologically aged skin constitute a novel class of UVA photosensitizers, capable of skin photooxidative damage.

Abstract
Singlet oxygen ((1)O(2)) is a product of several biological processes and can be generated in photodynamic therapy, through a photosensitization type II mechanism. (1)O(2) is able to interact with lipids, proteins and DNA, leading to cell killing and mutagenesis, and can be directly involved with degenerative processes such as cancer and aging. In this work, we analyzed the cytotoxicity and mutagenesis induced after direct treatment of wild type and the DNA repair fpg and/or mutY deficient Escherichia coli strains with disodium 3,3'-(1,4-naphthylidene) diproprionate endoperoxide (NDPO(2)), which releases (1)O(2) by thermodissociation. The treatment induced cell killing and mutagenesis in all strains, but the mutY strain showed to be more sensitive. These results indicate that even (1)O(2) generated outside bacterial cells may lead to DNA damage that could be repaired by pathways that employ MutY protein. As (1)O(2) is highly reactive, its interaction with cell membranes may generate secondary products that could react with DNA, leading to mutagenic lesions.

Abstract
Chronic exposure to sunlight plays a role in skin aging and carcinogenesis. The molecular mechanisms of photodamage by ultraviolet A, the sunlight's major ultraviolet constituent, are poorly understood. Here we provide evidence that advanced glycation end products on proteins are sensitizers of photo-oxidative stress in skin cells. Glycation is a process of protein damage by reducing sugars and other reactive carbonyl species leading to the formation of advanced glycation end products, which accumulate on long-lived proteins such as dermal elastin and collagen during skin aging. Growth inhibition as a result of advanced glycation end product photosensitization of ultraviolet A and solar-simulated light was demonstrated in human keratinocytes and fibroblasts. Using advanced glycation end product bovine serum albumin and advanced glycation end product collagen as model photosensitizers, ultraviolet A-induced formation of H2O2 was identified as the key mediator of skin cell growth inhibition as evidenced by complete protection by catalase treatment and equivalent growth inhibition of unirradiated cells treated with pre-irradiated advanced glycation end product protein. D-penicillamine protected against advanced glycation end product-photosensitized growth inhibition even when added following irradiation, suggesting the feasibility of therapeutic approaches for protection against skin ultraviolet A damage. Photosensitized growth inhibition increased with the degree of advanced glycation end product modification paralleled by the amount of H2O2 formed upon solar-simulated light irradiation of the protein. Photosensitization was not observed using bovine serum albumin modified with the major advanced glycation end product, Nepsilon-carboxymethyl-L-lysine, ruling out effects of cellular advanced glycation end product receptor (RAGE) stimulation. In contrast to bovine serum albumin, unglycated collagen showed photosensitization in CF3 fibroblasts and generation of H2O2 upon solar-simulated light irradiation. This study supports the hypothesis that advanced glycation end product-modified proteins are endogenous sensitizers of photo-oxidative cell damage in human skin by ultraviolet A-induced generation of reactive oxygen species contributing to photoaging and photocarcinogenesis.

Abstract
A water-soluble [18O]-labeled endoperoxide derived from N,N'-di(2,3-dihydroxypropyl)-1,4-naphthalene-dipropanamide (DHPN18O2) has been shown to act as a clean chemical source of [18O]-labeled molecular singlet oxygen. This allows the assessment of the singlet oxygen (1O2) reactivity toward biological targets such as DNA. The present work focuses on the qualitative identification of the main 1O2-oxidation products of 8-oxo-7,8-dihydro-2'-deoxyguanosine, which was achieved using high performance liquid chromatography coupled to electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). Thus, the [18O]-labeled and unlabeled imidazolone and oxazolone, together with the diastereoisomeric spiroiminodihydantoin nucleosides, were detected as the main degradation products. In addition, a modified nucleoside that exhibits similar features as those of the oxidized guanidinohydantoin molecule was detected. Our data strongly suggest that the imidazolone and oxazolone nucleosides are generated via the rearrangement of an unstable 5-hydroperoxide intermediate. Interestingly, the combined use of appropriate tools, including isotopically labeled singlet oxygen and the high- resolution HPLC-ESI-MS/MS technique, has allowed to shed new light on the 1O2-mediated oxidation reactions of guanine DNA components.

Abstract
Following the requirement for cells to cope with oxidative stress, there are cellular adaptation mechanisms at the level of gene expression. Much of what is known about oxidant-induced signaling in mammalian cells was found in experiments using hydrogen peroxide as an oxidant. However, since the biochemical reactivities of various oxidants significantly differ, 'oxidative stress' is not necessarily identical independent of the oxidant employed to bring it about. Here, the biological actions of peroxynitrite and singlet oxygen are presented, focusing on signaling effects. Peroxynitrite is generated in biological systems in the diffusion-controlled reaction of superoxide with nitrogen monoxide and is thus likely to be produced in the vicinity of activated macrophages. Singlet oxygen is generated by stimulated neutrophils in vivo and may further be generated photochemically, e.g. upon exposure of cells to ultraviolet A radiation. Exposure of cells to either of these oxidants elicits a cellular stress response, entailing the activation of signaling cascades that regulate proliferative and apoptotic responses, such as mitogen-activated protein kinase cascades or the phosphoinositide 3-kinase/Akt cascade. Two mechanisms for the oxidant-induced activation of a signaling cascade may be envisaged: (i) the indirect targeting of the cascade by interrupting negative regulation, and (ii) an activating oxidation of one of the constituting components of the cascade. Examples for both mechanisms in relation to peroxynitrite and singlet oxygen are discussed.

Abstract
beta-Carotene is discussed as an anti-oxidant micronutrient and singlet oxygen quencher in human skin, protecting against UV light-induced damage. However, we recently demonstrated that beta-carotene has a pro-oxidant potential in cultured human skin fibroblasts because it enhances the UVA induction of heme oxygenase-1 (HO-1). Herein, we further show that beta-carotene also strongly promotes the UVA induction of pro-inflammatory interleukin-6 (IL-6) in skin fibroblasts in vitro. Singlet oxygen quencher sodium azide abrogated up-regulation of IL-6, and likewise also of HO-1. In UVB-irradiated cells, beta-carotene did not modulate levels of IL-6 and HO-1. The observed effects might be relevant for UV-induced inflammatory processes.
