    Stepwise-Edited, Human Melanoma Models Reveal Mutations’ Effect on Tumor and Microenvironment

    The authors generated a progressive series of genome-edited human models of melanoma, in which they started from healthy human melanocytes and introduced mutations in up to five genes spanning six pathways commonly dysregulated in melanoma.

    Increased Mitophagy Protects Cochlear Hair Cells from Aminoglycoside-Induced Damage

    The authors found that PINK1-PRKN-mediated mitophagy was impaired in neomycin-treated hair cells. Additionally, they demonstrated that neomycin disrupted mitophagy through transcriptional inhibition of Pink1 expression, the key initiator of mitophagy.

    LncRNA-H19 in Fibroblasts Promotes Diabetic Wound Healing

    Scientists found that cutaneous PDGFRα+ fibroblast-expressing lncRNA-H19 accelerated the wound-healing process via promoting dermal fibroblast proliferation and macrophage infiltration in injured skin.

    Abstract

    Decoy Receptor 3 Is Involved in Epidermal Keratinocyte Commitment to Terminal Differentiation via EGFR and PKC Activation

    Decoy receptor 3 (DcR3) is a soluble receptor for Fas ligand, LIGHT and TL1A, but it also exerts effector functions. The authors found that the constitutive expression of the DcR3 gene and protein was progressively suppressed during terminal differentiation of keratinocytes.

    Adipose Mesenchymal Stem Cell-Derived Exosomes Promote Wound Healing Through the WNT/β-catenin Signaling Pathway in Dermal Fibroblasts

    Researchers obtained adipose-derived mesenchymal stem cell exosomes (ADMSC-Exos) and found that ADMSC-Exos significantly promoted the migration and proliferation of fibroblasts in a dose-dependent manner in vitro.

    Human iPSC-Derived-Keratinocytes, a Useful Model to Identify and Explore Pathological Phenotype of Epidermolysis Bullosa Simplex

    Investigators generated human induced pluripotent stem cell (hiPSC)-derived keratinocytes from patients carrying KRT5 dominant mutations and compared them to non-affected hiPSC-derived keratinocytes as well as their primary counterparts.

    Ablation of H+/Glucose Exporter SLC45A2 Enhances Melanosomal Glycolysis to Inhibit Melanin Biosynthesis and Promote Melanoma Metastasis

    Researchers used Slc45a2-deficient melanocyte and mouse models to elucidate the roles of Slc45a2 in melanogenesis and melanoma metastasis.

    Loss of ‘Epidermal Melanin Unit’ Integrity in Human Skin During Melanoma-Genesis

    Investigators focus on the early phases of melanomagenesis by discussing how the originating pigment cell of the melanocyte lineage can be influenced to embark on a wide range of tumor fates with distinctive microanatomical pathways.
