Skin aging is associated with a progressive decline in physiological functions, skin cancers and, ultimately, death. It may be categorized as intrinsic or extrinsic, whereby intrinsic aging is attributed to chrono-logical and genetic factors. At the molecular level, skin aging involves changes in protein conformation and function. The skin proteome changes constantly, mainly through carbonylation; an irreversible phenomenon leading to protein accumulation as toxic aggregates that impair cellular physiology and accelerate skin aging. This review details the central role of proteostasis during skin aging and why proteome protection may be a promising approach in mitigating skin aging. A comprehensive literature review of 87 articles focusing on the proteome, proteostasis, proteotoxicity, protein carbonylation, and the impact of the damaged proteome on aging, and in particular skin aging, was conducted. Skin aging is associated with deficiencies in the repair mechanisms of DNA, transcriptional control, mitochondrial function, cell cycle control, apoptosis, cellular metabolism, changes in hormonal levels secondary to toxicity of damaged proteins, and cell-to-cell communication for tissue homeostasis, which are largely controlled by proteins. In this context, a damaged proteome that leads to the loss of proteostasis may be considered as the first step in tissue aging. There is growing evidence that a healthy proteome plays a central role in skin and in maintaining healthy tissues, thus slow-ing down the process of skin aging. Hence, protecting the proteome against oxidative or other damage may be an appropriate strategy to prevent and delay skin aging.

Human skin provides both physical integrity and immunological protection from the external environment using functionally distinct layers, cell types and extracellular matrix. Despite its central role in human health and disease, the constituent proteins of skin have not been systematically characterized. Here, we combine advanced tissue dissection methods, flow cytometry and state-of-the-art proteomics to describe a spatially-resolved quantitative pro-teomic atlas of human skin. We quantify 10,701 proteins as a function of their spatial location and cellular origin. The resulting protein atlas and our initial data analyses demonstrate the value of proteomics for understanding cell-type diversity within the skin. We describe the quantitative distribution of structural proteins, known and previously undescribed proteins specific to cellular subsets and those with specialized immunological functions such as cytokines and chemokines. We anticipate that this proteomic atlas of human skin will become an essential community resource for basic and translational research (https://skin.science/).

ABSTRACT

Skin aging is a specific manifestation of the physiological aging process that occurs in virtually all organisms In this study, we used data independent acquisition mass spectrometry to perform a comparative analysis of protein expression in volar forearm skin samples from of 20 healthy young and elderly Chinese individuals. Our quantitative proteomic analysis identified a total of 95 differentially expressed proteins (DEPs) in aged skin compared to young skin. Enrichment analyses of these DEPs (57 upregulated and 38 downregulated proteins) based on the GO, KEGG, and KOG databases revealed functional clusters associated with immunity and inflammation, oxidative stress, biosynthesis and metabolism, proteases, cell proliferation, cell differentiation, and apoptosis. We also found that GAPDH, which was downregulated in aged skin samples, was the top hub gene in a protein-protein interaction network analysis. Some of the DEPs identified herein had been previously correlated with aging of the skin and other organs, while others may represent novel age-related entities. Our non-invasive proteomics analysis of human epidermal proteins may guide future research on skin aging to help develop treatments for age-related skin conditions and rejuvenation.
