    NK Cells in Hypoxic Skin Mediate a Trade-Off between Wound Healing and Antibacterial Defence

    The authors demonstrated that mice lacking the hypoxia-inducible factor-1α isoform in natural killer (NK) cells showed impaired release of the cytokines Interferon (IFN)-γ and granulocyte macrophage – colony stimulating factor as part of a blunted immune response.

    Large Scale Clinical Exome Sequencing Uncovers the Scope and Severity of Skin Disorders Associated with MC1R Genetic Variants

    Genetic variation in MC1R is a main determinant of red hair color phenotype and confers susceptibility to skin disorders. Scientists assessed the effects and function of MC1R variants identified in their clinical cohort of 135,947 participants with available exome sequencing using phenome-wide association scan.

    Abstract

    Staphylococcus aureus Uses the ArlRS and MgrA Cascade to Regulate Immune Evasion during Skin Infection

    Through a combination of in vitro assays, mouse models, and intravital imaging, researchers found that S. aureus immune evasion in skin was controlled by a cascade composed of the ArlRS two-component regulatory system and its downstream effector, MgrA.

    MMP1 Regulated by NEAT1/miR-361-5p Axis Facilitates the Proliferation and Migration of Cutaneous Squamous Cell Carcinoma via the Activation of Wnt Pathway

    Scientists found that the expression of matrix metallopeptidase 1 (MMP1) was up-regulated in cutaneous squamous cell carcinoma (CSCC) cells, and knockdown of MMP1 suppressed cell proliferation and invasion in CSCC.

    Fermitin Family Member 2 Promotes Melanoma Progression by Enhancing the Binding of P-α-Pix to Rac1 to Activate the MAPK Pathway

    Investigators identified fermitin family member 2 as a potential target in A375 cell line by siRNA library screening. They also validated the tumor suppressive role of kindlin-2 in vitro and in vivo.

    Rapid Signaling Reactivation after Targeted BRAF Inhibition Predicts the Proliferation of Individual Melanoma Cells from an Isogenic Population

    By tracking cell lineages over multiple days, the authors established that these cells indeed proliferated more than neighboring cells, thus establishing that rapid signaling reactivation predicts long-term vemurafenib resistance.

    Non-Thermal Atmospheric Pressure Plasma Activates Wnt/β-Catenin Signaling in Dermal Papilla Cells

    Human dermal papilla cells, isolated fresh hair follicles, and mouse back skin were exposed with the non-thermal atmospheric pressure plasma. Biological outcomes were measured using RNA-sequencing, RT-PCR, Western blots, and immunostaining.
