    CXCR2 Expression during Melanoma Tumorigenesis Controls Transcriptional Programs That Facilitate Tumor Growth

    The effects of a CXCR1/CXCR2 antagonist, SX-682, on melanoma tumorigenesis were evaluated in BrafV600E/Pten−/− and NRasQ61R/INK4a−/− mice and in melanoma cell lines.

    RIG-I Contributes to Keratinocyte Proliferation and Wound Repair by Inducing TIMP-1 Expression through NF-κB Signaling Pathway

    Mechanistically, retinoic acid inducible-gene I (RIG-I) promoted keratinocyte proliferation and wound repair by inducing TIMP-1 via the NF-κB signaling pathway.

    Abstract

    Design and Evaluation of a Skin-on-a-Chip Pumpless Microfluidic Device

    Viabilities of full-thick skin samples cultured on the microbioreactor and traditional tissue culture plate revealed that a precise controlled condition provided by the microfluidic enhanced tissue viability at least for seven days.

    Bacteriophage-Loaded Functional Nanofibers for Treatment of P. aeruginosa and S. aureus Wound Infections

    The novel fibers exhibited a reproducible fiber diameter range and morphology, while the mechanical fiber properties were ideal for application onto wounds. Immediate release kinetics for the phages were confirmed as well as the biocompatibility of the fibers with human skin cells.

    Lipid Droplets Are a Metabolic Vulnerability in Melanoma

    Single-cell RNA-sequencing of tumors showed a concordance between genes regulating pigmentation and those involved in lipid and oxidative metabolism. This state was conserved across human melanoma cell lines and patient tumors.

    Kinetics of RTK Activation Determine ERK Reactivation and Resistance to Dual BRAF/MEK Inhibition in Melanoma

    Single-cell analysis revealed that only a small subset of melanoma cells exhibited effective receptor tyrosine kinase (RTK) and ERK activation and developed persisters, despite uniform external stimuli.

    Dual Targeting of Melanoma Translation by MNK/eIF4E and PI3K/mTOR Inhibitors

    Investigators explored the mechanism of action of a highly specific PI3K/mTOR inhibitor, and Mnk inhibitor, alone and in combination, as well as their effect on the viability and invasiveness of melanoma cells.

    TNF-α Induced Extracellular Release of Keratinocyte High-Mobility Group Box 1 in Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: Biomarker and Putative Mechanism of Pathogenesis

    Epidermal high-mobility group box 1 (HMGB1) release from antitumor necrosis factor-alpha (TNF-α) treated, or doxycycline-inducible RIPK3 or Bak-expressing human keratinocyte cells was determined by western blot/ELISA.

    Differential Regulation of Cutaneous Immunity by Sensory Neuron Subsets

    Neuroimmune crosstalk in the skin, through interactions of primary sensory neurons with the immune system, has been shown to regulate host cutaneous defense, inflammation, and tissue repair. Scientists review current knowledge about the cellular and molecular mechanisms involved in this crosstalk.
