    Transcriptome Analysis Reveals Tumor Microenvironment Changes in Glioblastoma

    Over time, hallmark glioblastoma genes were not significantly altered. Instead, tumor purity decreased over time and was accompanied by co-increases in neuron and oligodendrocyte marker genes and, independently, tumor-associated macrophages.

    CD4+ T Cells Produce GM-CSF and Drive Immune-Mediated Glomerular Disease by Licensing Monocyte-Derived Cells to Produce MMP12

    Researchers identified a population of granulocyte-macrophage colony-stimulating factor–producing (GM-CSF) T cells that accumulated in the kidneys of patients with antineutrophil cytoplasmic antibody–associated glomerulonephritis.

    Abstract

    Circadian Clock Molecule REV-ERBα Regulates Lung Fibrotic Progression through Collagen Stabilization

    Investigators determined the role of REV-ERBα in fibrogenesis induced by bleomycin and Influenza A virus. Bleomycin exposure decreases the abundance of REV-ERBα, and mice dosed with bleomycin at night display exacerbated lung fibrogenesis.

    Protein Dynamics at Invadopodia Control Invasion–Migration Transitions in Melanoma Cells

    To study the interaction of invadopodia with focal adhesion and how invadopodia turn-over is associated with invasion-migration transition cycles, researchers investigated the role of Pyk2, cortactin, and Tks5 in invadopodia turnover and their relation with focal adhesions.

    Abstract

    Impact of Hyaluronan Size on Localization and Solubility of the Extracellular Matrix in the Mouse Brain

    Investigators established a simple method to simultaneously assess the molecular weight of hyaluronan in multiple crude biological samples.

    Abstract

    PYROXD1 Variants Cause an Overlapping Myopathy and Connective Tissue Disorder

    The authors described two female probands from unrelated families presenting with features of a congenital connective tissue disorder including osteopenia, blue sclera, soft skin, joint hypermobility, and neuromuscular junction dysfunction.

    Abstract

    Inhibition of Cdc37 Ameliorates Arthritis in Collagen-Induced Arthritis Rats by Inhibiting Synoviocyte Proliferation and Migration Through the ERK Pathway

    Investigators found that Cdc37 expression was upregulated in human rheumatoid synovia in contrast with the normal group. Cdc37 activated the ERK pathway to promote RA-FLS proliferation and migration in vitro.

    Abstract

    3D Bioprinting of Human Mesenchymal Stem Cells-Laden Hydrogels Incorporating MXene for Spontaneous Osteodifferentiation

    The MXene-incorporated gelatin methacryloyl and hyaluronic acid methacryloyl bioinks were prepared to explore if they have the potential to enable the spontaneous osteodifferentiation of hMSCs when the hMSCs-laden GelMA/HAMA-MXene bioinks were 3D printed.

    Abstract

    Co-Axial Electrospinning of PLLA Shell, Collagen Core Nanofibers for Skin Tissue Engineering

    Scientists produced a bilayer structure by gelling GeIMA in between two nanofiber membranes to imitate the epidermal and dermal layers of skin. Cytocompatibility properties of nanofiber membrane and bilayer structure were characterized by mono- and coculture of keratinocytes and fibroblasts, respectively.
