[PMID: 35998505 DOI: 10.1016/j.intimp.2022.109174] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 08/02/2022] [Accepted: 08/14/2022] [Indexed: 11/16/2022]
Abstract
Excessive exposure of the skin to ultraviolet radiation (UVR) causes oxidative stress, inflammation, immunosuppression, apoptosis, and changes in the extracellular matrix, which lead to the development of photoaging and photodamage of skin. At the molecular level, these pathological changes are mainly caused by the activation of related protein kinases and downstream transcription pathways, the increase of matrix metalloproteinase, the formation of reactive oxygen species, and the combined action of cytokines and inflammatory mediators. At present, the photostability, toxicity, and damage to marine ecosystems of most sun protection products in the market have affected their efficacy and safety. Another way is to use natural products produced by various marine species. Marine organisms have evolved a variety of molecular strategies to protect themselves from the harmful effects of ultraviolet radiation, and their unique chemicals have attracted more and more attention in the research of photoprotection and photoaging resistance. This article provides an extensive description of the recent literature on the potential of Marine-Derived Natural Compounds (MDNCs) as photoprotective and photoprotective agents. It reviews the positive effects of MDNCs in counteracting UV-induced oxidative stress, inflammation, DNA damage, apoptosis, immunosuppression, and extracellular matrix degradation. Some MDNCs have the potential to develop feasible solutions for related phenomena, such as photoaging and photodamage caused by UVR.

Benzalkonium chloride breaks down conjunctival immunological tolerance in a murine model. Mucosal Immunol 2013; 6:24-34.

Abstract
The impact of topical eye drops with benzalkonium chloride (BAK) as a preservative could involve more than the reported toxic effects on the ocular surface epithelium and ultimately affect the immune balance of the conjunctiva. We found that BAK not only impairs tolerance induction in a murine model, but leads to mild systemic immunization. Contrasting with antigen only-treated mice, there was no induction of interleukin 10-producing antigen-specific CD4(+) cells in BAK-treated animals. Moreover, the tolerogenic capacity of migrating dendritic cells (DCs) was reduced, apparently involving differential conditioning by soluble epithelial factors. Accordingly, epithelial cells exposed in vitro to BAK were less suppressive and failed to induce tolerogenic DCs in culture. As this effect of BAK was dependent on epithelial nuclear factor κB pathway activation, our findings may provide new therapeutic targets. Thus, tolerance breakdown by BAK should be considered an important factor in the management of glaucoma and immune-mediated ocular surface disorders.

Protein kinases and transcription factors activation in response to UV-radiation of skin: implications for carcinogenesis. Int J Mol Sci 2011; 13:142-72.

Abstract
Solar ultraviolet (UV) radiation is an important environmental factor that leads to immune suppression, inflammation, photoaging, and skin carcinogenesis. Here, we reviewed the specific signal transduction pathways and transcription factors involved in the cellular response to UV-irradiation. Increasing experimental data supporting a role for p38, MAPK, JNK, ERK1/2, and ATM kinases in the response network to UV exposure is discussed. We also reviewed the participation of NF-κB, AP-1, and NRF2 transcription factors in the control of gene expression after UV-irradiation. In addition, we discussed the promising chemotherapeutic intervention of transcription factors signaling by natural compounds. Finally, we focused on the review of data emerging from the use of DNA microarray technology to determine changes in global gene expression in keratinocytes and melanocytes in response to UV treatment. Efforts to obtain a comprehensive portrait of the transcriptional events regulating photodamage of intact human epidermis after UV exposure reveals the existence of novel factors participating in UV-induced cell death. Progress in understanding the multitude of mechanisms induced by UV-irradiation could lead to the potential use of protein kinases and novel proteins as specific targets for the prevention and control of skin cancer.

Abstract
DNA decoys have been developed for the inhibition of transcriptional regulation of gene expression. However, the present methodology lacks the spatial and temporal control of gene expression that is commonly found in nature. Here, we report the application of photoremovable protecting groups on nucleobases of nuclear factor κB (NF-κB) DNA decoys to regulate NF-κB-driven transcription of secreted alkaline phosphatase using light as an external control element. The NF-κB family of proteins is comprised of important eukaryotic transcription factors that regulate a wide range of cellular processes and are involved in immune response, development, cellular growth, and cell death. Several diseases, including cancer, arthritis, chronic inflammation, asthma, neurodegenerative diseases, and heart disease, have been linked to constitutively active NF-κB. Through the direct incorporation of caging groups into an NF-κB decoy, we were able to disrupt DNA:DNA hybridization and inhibit the binding of the transcription factor to the DNA decoy until UV irradiation removed the caging groups and restored the activity of the oligonucleotide. Excellent light-switching behavior of transcriptional regulation was observed. This is the first example of a caged DNA decoy for the photochemical regulation of gene expression in mammalian cells and represents an important addition to the toolbox of light-controlled gene regulatory agents.

Abstract
Prolonged and repeated exposure of the skin to ultraviolet light (UV) leads not only to aging of the skin but also increases the incidence of non-melanoma skin cancer (NMSC). Damage of cells induced by ultraviolet B (UVB) light both at the DNA level and molecular level initiates the activation of transcription factor pathways, which in turn regulate the expression of a number of genes termed the "UV response genes". Two such transcription factor families that are activated in this way are those of the nuclear factor-kappaB (NF-kappaB) and activator protein-1 (AP-1) families. These two transcription factor families have been identified to be involved in the processes of cell proliferation, cell differentiation and cell survival and therefore play important roles in tumorigenesis. The study of these two transcription factor pathways and the cross-talk between them in response to UVB exposure may help with the development of new chemopreventive strategies for the prevention of UVB-induced skin carcinogenesis.

Abstract
The nuclear factor-kappaB (NF-kappaB) family of dimeric transcription factors plays pivotal roles in physiologic and pathologic processes, including immune and inflammatory responses and development and progression of various human cancers. Inactive NF-kappaB dimers normally exist in the cytoplasm in association with inhibitor proteins belonging to the inhibitor of NF-kappaB (IkappaB) family of related proteins. Activation of NF-kappaB involves its release from IkappaB and subsequent nuclear translocation to induce expression of target genes. Intense research effort has revealed many distinct signaling pathways and mechanisms of NF-kappaB activation induced by immune and inflammatory stimuli. These aspects of NF-kappaB biology have been amply reviewed in the literature. However, those that involve DNA-damaging agents are less well understood, and multiple conflicting pathways and mechanisms have been described in the literature. In this review, we summarize the proposed mechanisms of NF-kappaB activation by various DNA-damaging agents, discuss the significance of such activation in the context of cancer treatment, and highlight some of the critical questions that remain to be addressed in future studies.
