    Human Skin Specific Long Noncoding RNA HOXC13-AS Regulates Epidermal Differentiation by Interfering with Golgi-ER Retrograde Transport

    In line with its enrichment in suprabasal keratinocytes, HOXC13-AS was found to be increasingly expressed during keratinocyte differentiation, but its expression was reduced by EGFR signaling.

    Protein Dynamics at Invadopodia Control Invasion–Migration Transitions in Melanoma Cells

    To study the interaction of invadopodia with focal adhesion and how invadopodia turn-over is associated with invasion-migration transition cycles, researchers investigated the role of Pyk2, cortactin, and Tks5 in invadopodia turnover and their relation with focal adhesions.

    Extracellular Vesicles of Commensal Skin Microbiota Alleviate Cutaneous Inflammation in Atopic Dermatitis Mouse Model by Reestablishing Skin Homeostasis

    The authors investigated the role of commensal skin bacterium Staphylococcus epidermidis-derived extracellular vesicles, in the context of atopic dermatitis.

    Abstract

    Non-Viral Transfection Methods Optimized for miRNA Delivery to Human Dermal Fibroblasts

    Researchers aimed to establish an effective method of transient miRNA mimic transfection into human dermal fibroblasts. The experimental conditions included three different methods: Physical/mechanical nucleofection, and two lipid‑based methods, Viromer® Blue and INTERFERin®.

    Abstract

    Co-Axial Electrospinning of PLLA Shell, Collagen Core Nanofibers for Skin Tissue Engineering

    Scientists produced a bilayer structure by gelling GeIMA in between two nanofiber membranes to imitate the epidermal and dermal layers of skin. Cytocompatibility properties of nanofiber membrane and bilayer structure were characterized by mono- and coculture of keratinocytes and fibroblasts, respectively.

    Abstract

    Inhibiting SCD Expression by IGF1R during Lorlatinib Therapy Sensitizes Melanoma to Ferroptosis

    The authors used a drug synergy screen that combined a ferroptosis inducer, RSL3, with 240 anti-tumor drugs from the FDA-approved drug library and identified lorlatinib to synergize with RSL3 in melanoma cells.

    Redox Phospholipidomics Discovers Pro-Ferroptotic Death Signals in A375 Melanoma Cells In Vitro and In Vivo

    Scientists demonstrated that RSL3-induced death of A375 melanoma cells in vitro was fully preventable by ferrostatin-1, suggesting their high susceptibility to ferroptosis.

    UHRF1/UBE2L6/UBR4-Mediated Ubiquitination Regulates EZH2 Abundance and Thereby Melanocytic Differentiation Phenotypes in Melanoma

    Investigators identified melanin pigment content as a major source of cellular heterogeneity in melanoma and compared RNAseq data from high-pigmented and low-pigmented melanoma cells, suggesting EZH2 as a master regulator of these states.

    Assessment of Genotoxicity Induced by Subchronic Exposure to Graphene in HaCaT Human Skin Cell Line

    Scientists tested in the HaCaT epithelial cells, in vitro, the effect of subchronic treatments with sublethal doses of four different, well-characterized graphene-based materials, two commercial graphene oxides, and two few-layer graphenes.
