TOP STORYSandwich-Structure Transferable Free-Form OLEDs for Wearable and Disposable Skin Wound Photomedicine When keratinocytes were irradiated with red sandwich-structure transferable OLED light, cell proliferation and cell migration increased by 26 and 32%, respectively. In the skin equivalent model, the epidermis thickness was increased by 39%. [Light Sci Appl] Full Article | |

PUBLICATIONS(Ranked by impact factor of the journal)DERMAL STEM CELLS & TISSUE REGENERATIONRenewed Proliferation in Adult Mouse Cochlea and Regeneration of Hair Cells Scientists showed that reprogramming of the adult inner ear induced renewed proliferation and regeneration of inner ear cell types. Co-activation of cell cycle activator Myc and inner ear progenitor gene Notch1 induced robust proliferation of diverse adult cochlear sensory epithelial cell types. [Nat Commun] Full Article Platelet Sonicates Activate Hair Follicle Stem Cells and Mediate Enhanced Hair Follicle Regeneration Investigators induced platelets in platelet-rich plasma to release factors by calcium chloride or by sonication where platelet lysates or the supernatants of platelet lysate were used to evaluate their effect on the hair follicle activation and regeneration. [J Cell Mol Med] Full Article Indirubin-Pregnane X Receptor-JNK Axis Accelerates Skin Wound Healing Researchers utilized an in vitro scratch injury assay and in vivo full-thickness mouse skin ulcer model and assessed wound closure. Indirubin significantly accelerated wound closure in both the scratch assay and the skin ulcer model. [Sci Rep] Full Article Polyplexes System to Enhance the LL-37 Antimicrobial Peptide Expression in Human Skin Cells Scientists modulated the conditions of used a non-viral system for transfection of primary human keratinocytes and fibroblasts, consisting of a polymer/plasmid DNA complex called polyplex and its effects on the expression of LL-37 antimicrobial peptide. [Tissue Eng Part A] Abstract The authors examined the biological effects of polydeoxyribonucleotide (PDRN) on mitochondrial biogenesis, melanogenesis, and connective tissue proteins in vitro. In a radical scavenging assay, PDRN showed antioxidant activities in a dose-dependent manner, and those activities could suppress cellular oxidative stress in skin cells. [Appl Biochem Biotechnol] Abstract Mitochondrial DNA Stress Signaling Protects the Nuclear Genome In cultured primary fibroblasts and cancer cells, the chemotherapeutic drug doxorubicin caused mitochondrial DNA damage and release, which led to cGAS-STING-dependent interferon-stimulated gene activation. [Nat Metab] Abstract SKIN CANCERS & DISORDERSAg@TiO2 Nanoprisms with Highly Efficient Near-Infrared Photothermal Conversion for Melanoma Therapy Ag NPs were synthesized using a two-step method and coated with TiO2 to obtain Ag@TiO2 NPs by a facile sol-gel method. Because of the oxide, Ag@TiO2 NPs exhibited remarkable high photothermal conversion efficiencies and biocompatibility in vivo and in vitro. [Chem Asian J] Abstract Overexpression of miR-199a-5p reduced the stemness of cutaneous squamous cell carcinomas and inhibited cell proliferation. By targeting the deacetylase Sirt1, miR-199a-5p inhibited cellular proteolysis of CD44 and reduced the CD44 intracellular domain (CD44ICD) release and nuclear translocation.

INDUSTRY NEWSDermavant Sciences announced that the first patient has been dosed in its Phase IIa vitiligo clinical trial for topical cerdulatinib. Cerdulatinib is a dual inhibitor of the Janus kinase (JAK) and spleen tyrosine kinase (Syk) pathways. [Dermavant Sciences] Press Release APR Applied Pharma Research sa announces that the US FDA has granted Orphan Drug Designation for its investigational drug code-named APR-TD011 for treatment of epidermolysis bullosa.

POLICY NEWSTufts to Remove Sackler Name from Medical Campus Tufts University will not return donations from the family that made its riches on opioids, but the university will start a $3 million endowment for addiction prevention and treatment. [The Scientist] Editorial Merck and Sanofi Buy Smaller Cancer Drug Firms at Big Premiums, Fueling Investor Excitement The drug giants Merck and Sanofi each said they would acquire a smaller drug maker for more than $2 billion – in each case, more than double the smaller company’s market capitalization – cheering investors about large companies’ appetite to execute buyouts in the biotechnology sector. [STAT News] Editorial House Republicans Fuel Capitol Hill Chaos with Competing Drug Pricing Bill Republicans are set to accelerate Capitol Hill’s drug pricing chaos with a new proposal to lower the cost of prescription medicines, according to a summary document obtained by STAT.
