    Establishment of Human Pluripotent Stem Cell-Derived Skin Organoids Enabled Pathophysiological Model of SARS-CoV-2 Infection

    A proteome map of COVID-19 skin was established and the susceptibility of human-induced pluripotent stem cell-derived skin organoids with hair follicles and nervous system was investigated, to SARS-CoV-2 infection.

    PlncRNA-1 Stimulates Hair Follicle Stem Cell Differentiation in Wound Healing via the EZH2/ZEB1/MAPK1 Axis

    PlncRNA-1 inhibited ZEB1 and activated MAPK1 signaling through upregulating EZH2, thereby enhancing the proliferation and differentiation of hair follicle stem cells and wound healing.

    Abstract

    ROS-Mediated Anti-Angiogenic Activity of Cerium Oxide Nanoparticles in Melanoma Cells

    Investigators established a robust synthesis method for faceted nanoceria with primary particle diameters of 5–6 nm. The nanoceria were not cytotoxic to a human melanoma cell line at doses up to 400 μg/mL and were dose-dependently internalized by the cells.

    CXCL4 Drives Fibrosis by Promoting Several Key Cellular and Molecular Processes

    Scientists confirmed that CXCL4 directly induced myofibroblast differentiation and collagen synthesis in different precursor cells, including endothelial cells, by stimulating endothelial-to-mesenchymal transition.

    CD29 Targeted Near-Infrared Photoimmunotherapy (NIR-PIT) in the Treatment of a Pigmented Melanoma Model

    The authors investigated the efficacy of CD29- and CD44-targeted NIR-PIT (CD29-PIT and CD44-PIT, respectively) in the B16 melanoma model, which was highly pigmented.

    Caffeine Improves the Cytotoxic Effect of Dacarbazine on B16F10 Murine Melanoma Cells

    Caffeine has been studied as a potentiating agent in chemotherapy against some types of cancer, but there are few reports on its effects on melanoma. Researchers investigated caffeine’s ability to enhance the effects of dacarbazine in vitro.

    SNF5, a Core Subunit of SWI/SNF Complex, Regulates Melanoma Cancer Cell Growth, Metastasis, and Immune Escape in Response to Matrix Stiffness

    Investigators suggested that stiffer substrate enhanced melanoma development by upregulating SNF5 expression, and SNF5 was a key mediator of stiffer matrix-induced immune evasion of melanoma cancer cells.

    Curcumin Suppresses Cell Proliferation and Triggers Apoptosis in Vemurafenib-Resistant Melanoma Cells by Downregulating the EGFR Signaling Pathway

    Vemurafenib-resistant A375.S2 cells were established, and the functional mechanism of the epidermal growth factor receptor (EGFR), serine–threonine kinase, and the extracellular signal-regulated kinase signaling induced by curcumin was investigated in A375.S2/VR cells in vitro.

    Abstract

    Deficiency of Vitamin D Receptor in Keratinocytes Augments Dermal Fibrosis and Inflammation in a Mouse Model of HOCl-Induced Scleroderma

    The authors demonstrated that the ablation of vitamin D receptors in keratinocytes greatly exacerbated dermal fibrosis in HOCl-induced scleroderma in mice.
