JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY 2024; 35:421-432. [PMID: 38326105 PMCID: PMC10921460 DOI: 10.1021/jasms.3c00315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 01/04/2024] [Accepted: 01/10/2024] [Indexed: 02/09/2024]
Abstract
Skin volatile emissions offer a noninvasive insight into metabolic activity within the body as well as the skin microbiome and specific volatile compounds have been shown to correlate with age, albeit only in a few small studies. Building on this, here skin volatiles were collected and analyzed in a healthy participant study (n = 60) using a robust headspace-solid phase microextraction (HS-SPME) gas chromatography-mass spectrometry (GC-MS) workflow. Following processing, 18 identified compounds were deemed suitable for this study. These were classified according to gender influences and their correlations with age were investigated. Finally, 6 volatiles (of both endogenous and exogenous origin) were identified as significantly changing in abundance with participant age (p < 0.1). The potential origins of these dysregulations are discussed. Multiple linear regression (MLR) analysis was employed to model age based on these significant volatiles as independent variables, along with gender. Our analysis shows that skin volatiles show a strong predictive ability for age (explained variance of 68%), stronger than other biochemical measures collected in this study (skin surface pH, water content) which are understood to vary with chronological age. Overall, this work provides new insights into the impact of aging on the skin volatile profiles which comprises both endogenously and exogenously derived volatile compounds. It goes toward demonstrating the biological significance of skin volatiles and will help pave the way for more rigorous consideration of the healthy "baseline" skin volatile profile in volatilomics-based health diagnostics development going forward.

Abstract
It is a significant challenge to perform painless invasive detection of inflammation progression in relation to the evolution of pH, redox potential, and reactive oxygen species (ROS) levels in an in situ and real-time manner. In this work, polydopamine-modified, silver nanoparticle-decorated poly (methyl methacrylate) microneedles (AgNPs@PDA@MNs) have been developed as a multiplexed surface enhanced Raman scattering (SERS) diagnostic platform. Using rhodamine 6G as the Raman signal molecule, the AgNPs@PDA@MNs demonstrated a significant enhancement with reasonable linearity in the range of 10-3-10-9 mol/L and the limit of detection is 1.0 × 10-10 mol/L 4-mercaptobenzoic acid, anthraquinone-2-carboxylic acid and para-aminothiophenol were covalently anchored on AgNPs@PDA@MNs SERS substrate. I1143/I1183, I1606/I1667 and I1143/I1077 were used as assay standards for pH, redox potential and ROS level detection, respectively. The SERS multiplexed transparent microneedles (SERS mtMNs) linearly responded to pH in the range of 4.0-8.0, redox potential in the range of 417.0-599.8 mV, and ROS levels in the range of 0-480 ng/mL, demonstrating a significant ability to detect complex inflammation in vivo, in situ and in real-time.

Abstract
The skin is constantly exposed to exogenous environmental stressors and has to cope with excessive oxidative stress and tissue damage. However, exposure to moderate environmental stressors may be beneficial for the cutaneous tissue and assist in protecting against oxidative damage via the enhanced activation of the nuclear factor erythroid 2-related factor 2-Kelch-like ECH-associated protein 1 (Nrf2-Keap1) pathway. Such moderate stressors can be found in various locations around the globe. In this manuscript, we chose to focus on the Dead Sea (DS) area as a test case to study the effect of moderate stressors on the cutaneous tissue because of the unique combinations of moderate stressors in this area. The exceptional location of the DS at an altitude of -438 meters below sea level (the lowest place on earth) is responsible for its rare accumulation of moderate stressors such as high-water salinity, high atmospheric pressure, and unique solar radiation. In this manuscript, we hypothesized that the unique solar radiation in the DS area generates moderate oxidative stress in the skin leading to the induction of intracellular electrophiles, which in turn can activate the protecting Nrf2-Keap1 pathway. We showed that exposure of human skin organ culture from the same donor to solar radiation at the DS resulted in significant activation of the Nrf2-Keap1 pathway, induction of phase II enzymes, and lower apoptotic activity compared to a nearby location at a higher altitude (Jerusalem +700 m). This remarkable effect of activating the Nrf2 protecting pathway and the importance and characteristics of the solar irradiation at the DS is discussed.

Abstract
This Discussion article aimed to explore the measurement of oxidation-reduction potential (ORP) in air moisture as an index of air pollution that may offer advantages over other measurements. First, the concept of air quality and the definition of air pollution levels are examined. The methods and purpose of measuring pollution in air moisture are then briefly explained. The article then highlights a number of preliminary observations and results of in-progress research on the effects of ORP in air moisture on human physical sensations, plant vitality, and proliferation of microorganisms. Further, the implications of controlling air moisture ORP for human exposure and health are discussed. In conclusion, the preliminary evidence suggests that air moisture ORP holds great potential as an indicator of air pollution and that the modulation of the ORP value in the environment can improve thermal sensation in humans, enhance plant health, and prevent the proliferation of toxic microorganisms. Future research is warranted to confirm these observations.

Do low molecular weight antioxidants contribute to the Protection against oxidative damage? The interrelation between oxidative stress and low molecular weight antioxidants based on data from the MARK-AGE study. Arch Biochem Biophys 2021; 713:109061. [PMID: 34662556 DOI: 10.1016/j.abb.2021.109061] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 10/12/2021] [Accepted: 10/13/2021] [Indexed: 12/31/2022]
Abstract
A redox steady state is important in maintaining vital cellular functions and is therefore homeostatically controlled by a number of antioxidative agents, the most important of which are enzymes. Oxidative Stress (OS) is associated with (or/and caused by) excessive production of damaging reactive oxygen and/or nitrogen species (ROS, RNS), which play a role in many pathologies. Because OS is a risk factor for many diseases, much effort (and money) is devoted to early diagnosis and treatment of OS. The desired benefit of the "identify (OS) and treat (by low molecular weight antioxidants, LMWA)" approach is to enable selective treatment of patients under OS. The present work aims at gaining understanding of the benefit of the antioxidants based on interrelationship between the concentration of different OS biomarkers and LMWA. Both the concentrations of a variety of biomarkers and of LMWA were previously determined and some analyses have been published by the MARK-AGE team. For the sake of simplicity, we assume that the concentration of an OS biomarker is a linear function of the concentration of a LMWA (if the association is due to causal relationship). A negative slope of this dependence (and sign of the correlation coefficient) can be intuitively expected for an antioxidant, a positive slope indicates that the LMWA is pro-oxidative, whereas extrapolation of the OS biomarker to [LMWA] = 0 is an approximation of the concentration of the OS biomarker in the absence of the LMWA. Using this strategy, we studied the effects of 12 LMWA (including tocopherols, carotenoids and ascorbic acid) on the OS status, as observed with 8 biomarkers of oxidative damage (including malondialdehyde, protein carbonyls, 3-nitrotyrosine). The results of this communication show that in a cross-sectional study the LMWA contribute little to the redox state and that different "antioxidants" are very different, so that single LMWA treatment of OS is not scientifically justified assuming our simple model. In view of the difficulty of quantitating the OS and the very different effects of various LMWA, the use of the "identify and treat" approach is questionable.

Abstract
The human skin is a lush microbial habitat which is occupied by a wide array of microorganisms. Among the most common inhabitants are Staphylococcus spp., namely Staphylococcus epidermidis and, in ≈20% of healthy individuals, Staphylococcus aureus. Both bacteria have been associated with cutaneous maladies, where they mostly arrange in a biofilm, thus achieving improved surface adhesion and stability. Moreover, our skin is constantly exposed to numerous oxidative environmental stressors, such as UV-irradiation. Thus, skin cells are equipped with an important antioxidant defense mechanism, the Nrf2–Keap1 pathway. In this work, we aimed to explore the morphology of S. aureus and S. epidermidis as they adhered to healthy human skin and characterize their matrix composition. Furthermore, we hypothesized that the localization of both types of bacteria on a healthy skin surface may provide protective effects against oxidative stressors, such as UV-irradiation. Our results indicate for the first time that S. aureus and S. epidermidis assume a biofilm-like morphology as they adhere to ex vivo healthy human skin and that the cultures’ extracellular matrix (ECM) is composed of extracellular polysaccharides (EPS) and extracellular DNA (eDNA). Both bacterial cultures, as well as isolated S. aureus biofilm eDNA, conferred cutaneous protection against UVB-induced apoptosis. This work emphasized the importance of skin microbiota representatives in the maintenance of a healthy cutaneous redox balance by activating the skin’s natural defense mechanism.

Involvement of RAGE and Oxidative Stress in Inflammatory and Infectious Skin Diseases. Antioxidants (Basel) 2021; 10:antiox10010082. [PMID: 33435332 PMCID: PMC7827747 DOI: 10.3390/antiox10010082] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 12/24/2020] [Accepted: 01/06/2021] [Indexed: 12/20/2022] Open
Abstract
The surface receptor for advanced glycosylation end-products (RAGE) and its soluble (sRAGE) and endogenous secretory (EN-RAGE) forms belong to the superfamily of toll-like receptors and play important roles in inflammation and autoimmunity, directly or through binding with advanced glycosylation end-products (AGE) and advanced oxidation protein products (AOPP). We reviewed the literature on the role of RAGE in skin diseases. Research in this field is still rather limited (28 articles) but suggests the involvement of RAGE and RAGE-related pathways in chronic inflammatory diseases (lupus, psoriasis, atopic dermatitis, and lichen planus), infectious diseases (leprosy, Staphylococcus aureus-induced skin lesions), alterations of the repairing processes in diabetic skin, systemic sclerosis, and ulcers. These data prompt further research in this field, which not only will be useful to better understand the pathogenetic mechanisms of diseases, but is also likely to have intriguing clinical implications. Indeed, when their role in the complex and multifactorial inflammatory balance will be adequately defined, RAGE and related molecules could be used as markers of disease severity and/or response to treatment. Moreover, future promising therapeutic perspectives could be topical administration of some of these molecules (e.g., sRAGE) to modulate local inflammatory response and/or the development of anti-RAGE antibodies for systemic treatment.
