Nevertheless, there is a paucity of studies investigating the potential of PS in protecting the skin against photoaging. The present study aimed to assess the effectiveness of PS extracts in preventing photoaging and elucidating the molecular mechanisms involved in using immortalized human keratinocytes (HaCaT) and hairless mice. The major bioactive constituents of PS were identified as p-coumaric acid, isoquercitrin, quercetin-3-O-glucuronide, and quercetin. Aqueous extracts of PS exhibited the ability to mitigate UVB-induced cellular damage and diminished ROS generation in HaCaT cells. Moreover, treatment with PS effectively attenuated the upregulated expression of matrix metalloproteinase-1 (MMP-1) and collagen degradation induced by UVB exposure. The property of PS to counteract photoaging was related to its capacity to inhibit the UVB-induced phosphorylation of mitogen-activated protein kinase (MAPK) and suppress the subsequent activation of activator protein 1 (AP-1) signaling pathways. Moreover, in hairless mice exposed to UVB radiation, the application of PS significantly alleviated the development of skin wrinkles, diminished epidermal thickening, and mitigated collagen degradation. Notably, PS treatment resulted in the downregulation of the UVB-activated MAPK/AP-1/MMP-1 pathway in mouse skin tissues. These findings suggest that PS has the potential to serve as a therapeutic agent for treating photoaging, holding promises in both cosmeceutical and pharmaceutical applications.</p></div>","PeriodicalId":375,"journal":{"name":"Journal of Photochemistry and Photobiology","volume":"20 ","pages":"Article 100228"},"PeriodicalIF":3.261,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666469024000034/pdfft?md5=bc61a4676e744656d068de5daa18b773&pid=1-s2.0-S2666469024000034-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139555654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its precise molecular mechanisms, especially within the green light spectrum, remain elusive. In this study, we investigated the anti-inflammatory mechanisms of 520 nm green light in primary human keratinocytes (KCs) exposed to the contact sensitizer 2,4-dinitrochlorobenzene (DNCB). Our data revealed that green light effectively reduces the mRNA expression of pro-inflammatory cytokines <em>IL-6, IL-8</em>, and <em>TNF-α</em>, comparably to the effect of dexamethasone, a conventional anti-inflammatory agent. As Nuclear factor erythroid-2-related factor 2 (Nrf2) is involved in the red light response, we explored Nrf2′s role in green light anti-inflammatory activity. Green light exposure activated the Nrf2 pathway, leading to Nrf2 increased accumulation in KCs and the induction of Nrf2 target genes, including HO-1 and GCLC. Invalidation of Nrf2 with si-RNA diminished the green light's regulatory effect, indicating Nrf2′s essential role in the green light's anti-inflammatory action. As the Transient Receptor Potential Vanilloid 1 (TRPV1) channel is a potential target for green light, we investigated its role in PBM response. Blocking TRPV1 with capsazepine (CPZ) abolished the anti-inflammatory effect of green light and prevented the upregulation of Nrf2 target genes. This finding highlights TRPV1′s integral role in green light beneficial activity via the activation of the Nrf2 pathway. Overall, our study identifies TRPV1 and Nrf2 as critical players in the green light response, highlighting the versatility of PBM in controlling skin inflammation.</p></div>","PeriodicalId":375,"journal":{"name":"Journal of Photochemistry and Photobiology","volume":"20 ","pages":"Article 100227"},"PeriodicalIF":3.261,"publicationDate":"2024-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666469024000022/pdfft?md5=0ff94c1a7a4415d3f5f891d61bc2ad48&pid=1-s2.0-S2666469024000022-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139464585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
