    Abstract

    LOXL2 from Human Amniotic Mesenchymal Stem Cells Accelerates Wound Epithelialization by Promoting Differentiation and Migration of Keratinocytes

    Investigators observed increased migration and reduced proliferation and differentiation when keratinocytes were co-cultured in media conditioned by human amniotic epithelial cell and human amniotic mesenchymal stem cells.

    Cellular Senescence Promotes Skin Carcinogenesis through p38MAPK and p44/p42MAPK Signaling

    Researchers showed for the first time that senescent cells were tumor promoters, not tumor initiators, and that they stimulated skin carcinogenesis by elevating p38 MAPK and MAPK/ERK signaling.
    [Cancer Research]

    Abstract

    Bromodomain Epigenetic Protein Promotes Metastatic Potential in Melanoma Cells via Increased Invasiveness and Decreased Macrophage-Mediated Phagocytosis

    The authors have identified a unique dual role of BRD4 in melanoma cell migration/invasion, and in maintaining innate-immune checkpoint that might prevent macrophage mediated eradication of metastatic melanoma cells.

    Abstract

    BRN2 Expression Increases Anoikis Resistance in Melanoma

    Scientists investigated the effect of BRN2 expression in melanoma cells with no or low constitutive expression using a doxycycline-inducible system.

    Elevated IL-22 in Psoriasis Plays an Anti-Apoptotic Role in Keratinocytes through Mediating Bcl-xL/Bax

    Investigators demonstrated that IL-22 might play an anti-apoptosis role on keratinocytes to balance cell proliferation and apoptosis in psoriatic epidermis.

    Geometric Regulation of Histone State Directs Melanoma Reprogramming

    Scientists uncovered a relationship between geometric features at perimeter regions of melanoma aggregates, and reprogramming to a stem cell-like state through histone marks H3K4Me2 and H3K9Ac.
