TOP STORYDysfunction of Hair Follicle Mesenchymal Progenitors Contributes to Age-Associated Hair Loss Using laser ablation and fate mapping, investigators showed that hair follicle dermal stem cells (hfDSCs) reconstituted damaged dermal papilla and maintained hair growth, suggesting that hfDSC dysfunction may trigger degeneration of the inductive niche.

PUBLICATIONS(Ranked by impact factor of the journal)DERMAL STEM CELLS & TISSUE REGENERATIONThe authors investigated the effects of nintedanib on keloid fibroblasts in both in vitro and ex vivo models. They found that nintedanib dose-dependently suppressed cell proliferation, induced G0/G1 cell cycle arrest, and inhibited migration and invasion of keloid fibroblasts. [Acta Pharmacol Sin] Abstract Scientists found that livin expression was upregulated after being stimulated with oncostatin M (OSM) at both the transcription and protein level. OSM promoted HaCaT cell survival in oxidative stress conditions, regulated through ERK and STAT3 signaling pathways. [Exp Physiol] Abstract SKIN CANCERS & DISORDERSMALT1 Targeting Suppresses CARD14-Induced Psoriatic Dermatitis in Mice Researchers showed that inducible keratinocyte-specific expression of CARD14E138A in mice rapidly induced epidermal thickening and inflammation as well as increased expression of several genes associated with psoriasis in humans. [EMBO Rep] Abstract | Graphical Abstract Regulation of eIF2α by RNF4 Promotes Melanoma Tumorigenesis and Therapy Resistance The authors described that by stabilizing key melanoma oncoproteins, the ubiquitin ligase RNF4 promoted tumorigenesis and conferred resistance to targeted therapy in melanoma cells, xenograft mouse models and patient samples. [J Invest Dermatol] Full Article Melanoma cancer cells experiencing stress from oncogene inhibition up-regulated the expression of Polκ and shifted its localization from the cytoplasm to the nucleus. This effect was phenocopied by inhibition of the kinase mTOR, by induction of ER stress, or by glucose deprivation. [Sci Signal] Full Article Scientists showed that transglutaminase 2 (TG2) mediated the upregulation of cytokines and chemokines by activating NF-κB in imiquimod (IMQ)-treated keratinocytes. TG2-deficient mice exhibited reduced psoriatic inflammation in skin treated with IMQ. [Cell Death Dis] Full Article Researchers investigated the effects of miR-203 on the behaviors of cutaneous squamous cell carcinoma cells and possible mechanisms associated with protein regulator of cytokinesis-1 and the Wnt/β-catenin signaling pathway. [Mol Ther Nucleic Acids] Abstract | Graphical Abstract 22β-Hydroxytingenone Reduces Proliferation and Invasion of Human Melanoma Cells 22β-hydroxytingenone (22-HTG) interfered with important characteristics of cancer, with anti-proliferative and anti-invasive effects against melanoma cells. The data suggested that 22-HTG was an effective substance against melanoma cells and should be considered as an anticancer agent.

REVIEWSRegulatory T Cells in Skin Injury: At the Crossroads of Tolerance and Tissue Repair Scientists focus on recently discovered interactions between lymphocytes and nonhematopoietic cells during wound healing and discuss how these interactions are regulated both by “classical” suppressive mechanisms of regulatory T cells and by “nonclassical” reparative functions.

INDUSTRY NEWSMelanoma Research Alliance Announces $11 Million for 26 Grant Awards to Advance Melanoma Research With the world’s attention focused on the response to COVID-19, the Melanoma Research Alliance (MRA) knows that long after this pandemic has ended, melanoma research will still be urgently needed. To this end, and in recognition of Melanoma Awareness Month, the MRA is proud to announce funding for 26 research awards totaling $10.9 million. [Melanoma Research Alliance] Press Release Menlo Therapeutics Inc. have announced that its wholly-owned subsidiary, Foamix Pharmaceuticals Ltd. has entered into a licensing agreement with specialty pharmaceutical company Cutia Therapeutics Ltd., for AMZEEQ™ topical foam, as well as its other topical minocycline product candidates.

POLICY NEWSStudents Stand Up for Sub-Contracted Workers amid COVID-19 Crisis Students at a number of universities have been advocating for the payment of employees, and especially contracted workers who are more vulnerable to layoffs, as campuses shut down during the COVID-19 pandemic. [The Scientist] Editorial As COVID-19 Forces Conferences Online, Scientists Discover Upsides of Virtual Format As the novel coronavirus outbreak shutters businesses and disrupts everyday life for billions around the globe, massive annual conferences and small society meetings alike have moved online. The new format poses numerous technical and organizational challenges, but it also offers opportunities- for reaching wider audiences, reducing the carbon footprint of meeting travel, and improving diversity and equity.
