    Commensal Microbiome Promotes Hair Follicle Regeneration by Inducing Keratinocyte HIF-1α Signaling and Glutamine Metabolism

    Using a model of organ regeneration called wound-induced hair follicle neogenesis, scientists identified skin-resident bacteria as key modulators of keratinocyte metabolism, demonstrating a positive correlation between bacterial load, glutamine metabolism, and regeneration.

    Abstract

    Generation of Innervated Cochlear Organoid Recapitulates Early Development of Auditory Unit

    Investigators developed cochlear organoids with functional peripheral auditory circuity in a staging three-dimensional co-culture system by initially reprogramming cochlear progenitor cells with increased proliferative potency that could be long-term expanded.

    Stability and Biosafety of Human Epidermal Stem Cell for Wound Repair: Preclinical Evaluation

    Nude mice were used to prepare a full-thickness skin defect wound model to detect the repair effect of epidermal stem cells (EpiSCs). The biosafety of EpiSCs was double tested in vitro and in vivo.

    A Unique Hyperdynamic Dimer Interface Permits Small Molecule Perturbation of the Melanoma Oncoprotein MITF for Melanoma Therapy

    Using chromatin immunoprecipitation assay and RNA sequencing, scientists showed that compound TT-012 inhibited the transcriptional activity of microphthalmia transcription factor (MITF) in B16F10 melanoma cells.

    Abstract

    Pyruvate Kinase M2 Mediates Il-17 Signaling in Keratinocytes Driving Psoriatic Skin Inflammation

    Specific depletion of pyruvate kinase M2 in keratinocytes attenuated the development of experimental psoriasis by reducing the production of pro-inflammatory mediators.

    Transglutaminase Type 2-Dependent Crosslinking of IRF3 in Dying Melanoma Cells

    Researchers demonstrated that upon doxorubicin treatment transglutaminase type 2 translocated into the nucleus of apoptotic melanoma cells, interacting with interferon regulatory factor 3 (IRF3) dimers.
