    An Anti-Oxidative and Active Shrinkage Hydrogel Integratedly Promotes Re-Epithelization and Skin Constriction for Enhancing Wound Closure

    The antioxidative active-shrinkage hydrogel relieved overactivated inflammation, prevented cellular apoptosis, and promoted fibroblast migration in vitro by reducing excessive reactive oxygen species.

    Single-Cell Analysis of Psoriasis Resolution Demonstrates an Inflammatory Fibroblast State Targeted by IL-23 Blockade

    Investigators performed longitudinal single-cell RNA-sequencing in individuals with psoriasis receiving IL-23 inhibitor therapy. They demonstrated that IL-23 blockade causes marked gene expression shifts, with fibroblast and myeloid populations displaying the most extensive changes at day 3.

    Collagen I Protects Human Keratinocytes HaCaT against UVB Injury via Restoring PINK1/Parkin-Mediated Mitophagy

    Cells grown on plates coated by molecular collagen I, but not fibrillar collagen I, acquired certain resistance against UVB damages, as shown by increased survival and reduced apoptosis.

    ANKRD1 Is a Mesenchymal-Specific Driver of Cancer-Associated Fibroblast Activation Bridging Androgen Receptor Loss to AP-1 Activation

    Investigators identified ANKRD1 as a mesenchymal-specific transcriptional coregulator under direct androgen receptor negative control in human dermal fibroblasts and a key driver of cancer-associated fibroblasts conversion, independent of cellular senescence.

    DNA Damage Remodels the MITF Interactome to Increase Melanoma Genomic Instability

    Researchers showed that the microphthalmia-associated transcription factor (MITF), a lineage addition oncogene that coordinates many aspects of melanocyte and melanoma biology, played a nontranscriptional role in shaping the DNA damage response.

    Abstract

    Saracatinib Inhibits Necroptosis and Ameliorates Psoriatic Inflammation by Targeting MLKL

    In an imiquimod-induced psoriasis mouse model, saracatinib effectively blocked mixed lineage kinase domain-like protein (MLKL) phosphorylation and inflammatory responses in vivo.

    Differential Histone Acetylation and Super-Enhancer Regulation Underlie Melanoma Cell Dedifferentiation

    The authors identified ITGA3 gene as marked by a super-enhancer element in the Epgn3 invasive cells. Silencing of ITGA3 enhanced invasiveness in both in vitro and in vivo systems suggesting it as a negative regulator of invasion.
