Here, we examine a risk variant in the <i>aquaporin 3</i> (<i>AQP3</i>) promoter and propose a mechanistic link between genotype to altered autophagy, skin barrier integrity, and wound healing in AD. A GWAS involving 1261 AD cases and 4062 controls of Chinese ancestry from the Singapore–Malaysia cohort was performed. Linkage disequilibrium (LD) analysis and cis-eQTL datasets were used to assess regulatory associations. Functional effects of promoter variants were validated using in vitro luciferase assays and ex vivo transcriptomic profiling. In vitro experiments in HaCaT keratinocytes investigated the effect of siRNA-mediated <i>AQP3</i> knockdown on autophagy, skin barrier integrity, and wound closure. A discovery GWAS identified significant association between AD and SNP rs12555686 (<i>p</i> = 1.67 × 10<sup>−11</sup>, OR = 1.89), located in the promoter of <i>AQP3</i>. Two additional SNPs in strong LD (rs2231225, rs3758279) formed a major haplotype associated with reduced <i>AQP3</i> expression. Reduced <i>AQP3</i> expression was associated with decreased autophagy markers (<i>Beclin1</i>, <i>ATG5</i>, <i>ATG12</i>, <i>GABARAPL2, LAMP2, ATG4C</i>), increased senescence markers (<i>p21</i>, <i>GADD45A</i>, <i>SERPINE1</i>), and elevated inflammatory cytokines (<i>IL8</i>, <i>IL1B</i>, <i>TNF</i>). Lastly, <i>AQP3</i> knockdown in HaCaT keratinocytes reduced steady-state LC3B-II/LC3B-I ratio, reduced occludin expression, and delayed wound healing in vitro.

Accurate wound assessment is imperative for measuring and longitudinal monitoring of disease activity and for determining the most accurate treatment. In this work, we describe the annotation of clinical images from EB patients and the subsequent training of both classical convolutional neural networks and state-of-the-art transformer-based architectures for the segmentation of various categories of EB skin wounds. Utilising our dataset of 260 EB images from 18 patients and the corresponding 536 expert-annotated segmentation masks, we train and evaluate five different model architectures and compare their performance against human inter-annotator agreement. External evaluation was not possible because no comparable annotated EB datasets are available. Our results demonstrate that transformer-based models, particularly Mask2Former, achieve near-expert-level segmentation accuracy in five of the seven categories and even surpass human inter-annotator agreement in two. Models based on convolutional neural networks perform noticeably worse and generally fail to accurately segment rarely occurring classes. Averaged over all categories, Mask2Former achieved a mean dice similarity coefficient (DSC) of 52.9%, compared to an inter-annotator agreement of 55.9%. These results indicate that Mask2Former has the potential to serve as a clinical decision support system to improve wound segmentation and categorization.

Approximately one-third of patients with AI harbour loss-of-function mutations in <i>NCSTN</i>. Whether NCSTN loss contributes to cSCC development remains unclear. To address this, we first examined its expression pattern in cSCC tissues. Interestingly, NCSTN expression was significantly decreased in cSCC tissues by immunohistochemistry (IHC) and Western blotting. Furthermore, loss of NCSTN promoted cSCC cell proliferation and migration in vitro and tumour growth in vivo. Proteomic analysis revealed that NCSTN deficiency promoted cell proliferation through activation of the MAPK/ERK signalling pathway, accompanied by reduced CLDN3 expression and alterations in cell-adhesion-related pathways. To validate the functional relevance of this signalling axis in vivo, we treated NCSTN-knockdown tumour-bearing mice with the ERK inhibitor SCH772984, which effectively suppressed tumour growth.

This scoping review summarises the extent of research into these therapies, including mechanisms of action, clinical translation and artificial modifications.

Immunomodulation, growth stimulation, angiogenesis and anti-apoptosis are the main mechanisms by which these therapies exert their effect, and initial reports provide some evidence that these therapies could be useful clinically. Nevertheless, such preliminary evidence is limited by study heterogeneity, short follow-up durations and small sample sizes. Various modifications to these therapies, such as preconditioning, are also being explored to increase treatment yield. Although infection and multi-organ effects are common safety concerns, current literature has also yet to establish long-term safety.

Post-translational modifications (PTMs) represent a key regulatory layer by modulating protein function, localization and interactions under UV stress. This review discusses the mechanistic involvement of PTMs in UV-induced skin damage and summarizes emerging PTM-related photoprotective strategies. Phosphorylation is a central mediator of UV-induced signal transduction, driving activation of the epidermal growth factor receptor (EGFR) and its downstream signalling pathways. Acetylation exerts distinct regulatory effects: histone acetylation primarily regulates transcription of inflammation-related genes and matrix metalloproteinases (MMPs), while non-histone acetylation modulates cellular senescence and mitochondrial antioxidant defence through modification of key proteins. Ubiquitination regulates protein degradation and, through non-degradative modifications, participates in DNA damage recognition and nucleotide excision repair (NER). Furthermore, other PTMs, including methylation, glycosylation, citrullination, SUMOylation and poly(ADP-ribosyl)ation (PARylation), participate in diverse regulatory processes during UV-induced cutaneous alterations. Experimental and emerging interventions associated with PTMs in UV-induced skin damage range from natural extracts to small-molecule agents and mainly include upstream-level modulation of oxidative stress, metabolic status or key effector protein function, as well as enzyme-level modulation of PTM writers and erasers. Different classes of PTMs contribute to UV-induced skin damage through distinct regulatory mechanisms. Further studies should explore the roles of emerging and less-characterized PTMs and evaluate interventions targeting PTM-regulating enzymes in physiologically relevant skin models.</p>","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"35 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13535276/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148873400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DPP4 is an exopeptidase that cleaves a wide array of substrates across different cell types. Here, we investigate whether modulation of lipid-regulating DPP4 substrates is sufficient to preserve lipid content in WNT-activated dermal adipocytes. Using two complementary strategies, we found that supplementation with the DPP4 substrates Neuropeptide Y (NPY) and Glucose-dependent Insulinotropic Peptide (GIP) can partially protect lipid content in dermal adipocytes.
