    KDM5B Promotes Immune Evasion by Recruiting SETDB1 to Silence Retroelements

    Investigators showed that in mouse melanoma models, depleted KDM5B — an H3K4 demethylase that was critical for melanoma maintenance and drug resistance — induced robust adaptive immune responses and enhanced responses to immune checkpoint blockades.

    MiR-193b-3p–ERBB4 Axis Regulates Psoriasis Pathogenesis via Modulating Cellular Proliferation and Inflammatory-Mediator Production of Keratinocytes

    Researchers confirmed the downregulation of miR-193b-3p in psoriasis patients, psoriasis-like inflammatory cellular models, and an imiquimod-induced mouse model.

    Characterization of Chromatin Accessibility in Psoriasis

    The authors systematically profiled chromatin accessibility on Th1, Th2, Th1-17, Th17, and Treg cells and found that chromatin remodeling contributed significantly to the pathogenesis of the disease.

    Abstract

    Increased ACTL6A Occupancy within mSWI/SNF Chromatin Remodelers Drives Human Squamous Cell Carcinoma

    Scientists explained the specificity of the role of mammalian SWI/SNF (BAF) subunit actin-like 6a (ACTL6A) amplification in squamous cell carcinomas and demonstrated that ACTL6A overexpression led to its stoichiometric assembly into BAF complexes.

    Lysosomal Zn2+ Release Triggers Rapid, Mitochondria-Mediated, Non-Apoptotic Cell Death in Metastatic Melanoma

    Investigators reported that mucolipin TRP channel 1, a lysosomal Ca2+ and Zn2+ release channel that regulated multiple aspects of lysosome function, was dramatically upregulated in metastatic melanoma cells compared to normal cells.

    DNA-Methylation Patterns Imply a Common Cellular Origin of Virus- and UV-Associated Merkel Cell Carcinoma

    Researchers used a DNA-methylation pattern approach and uncovered evidence regarding the cell of origin of classical virus-associated merkel cell carcinomas (MCC) and virus-negative MCCs that were driven by UV-light-induced mutation cell lines, that is, cell lines with a neuroendocrine growth pattern.

    HOTAIR/Sp1/miR-199a Critically Regulates Cancer Stemness and Malignant Progression of Cutaneous Squamous Cell Carcinoma

    The long non-coding RNA, HOX antisense intergenic RNA (HOTAIR), was a well-characterized oncogene in multiple human cancers, but not in cutaneous squamous cell carcinoma (CSCC). The authors investigated the potential role of HOTAIR in the stemness of CSCC.

    Abstract

    Kinectin1 Depletion Promotes EGFR Degradation via the Ubiquitin-Proteosome System in Cutaneous Squamous Cell Carcinoma

    Scientists demonstrated that kinectin1 knockdown induced epidermal growth factor receptor (EGFR) degradation in cutaneous squamous cell carcinoma cells and promoted the ubiquitin-proteasome system, and that this effect was tumor cell-specific.

    Determination of In Vivo Virtue of Dermal Targeted Combinatorial Lipid Nanocolloidal Based Formulation of 5-Fluorouracil and Resveratrol against Skin Cancer

    Investigators confirmed the superior efficacy of linogel in terms of marked improvement in the nucleus and subcellular structures in photomicrographs, through histopathological and ultrastructural analysis, which fulfilled all the criteria of dermal application.

    K15 Promoter-Driven Enforced Expression of NKIRAS Exhibits Tumor Suppressive Activity against the Development of DMBA/TPA-Induced Skin Tumors

    Researchers clarified how NKIRAS acted on cellular transformation, and generated transgenic mice in which NKIRAS2 was forcibly expressed using a cytokeratin 15 promoter, which was mainly activated in follicle bulge cells.
