    GPR177 in A-Fiber Sensory Neurons Drives Diabetic Neuropathic Pain via WNT-Mediated TRPV1 Activation

    Scientists reported that the orphan G protein–coupled receptor 177 (GPR177) in A-fiber neurons drove diabetic neuropathic pain via WNT5a-mediated activation of transient receptor potential vanilloid receptor-1 (TRPV1) ion channel.

    Promoter and Enhancer RNAs Regulate Chromatin Reorganization and Activation of miR-10b/HOXD Locus, and Neoplastic Transformation in Glioma

    The authors demonstrated that the entire miR-10b-hosting HOXD locus was activated in glioma via the cis-acting mechanism involving 3D chromatin reorganization and CTCF-cohesin-mediated looping.

    STAT3 Is a Biologically Relevant Therapeutic Target in H3K27M-Mutant Diffuse Midline Glioma

    Researchers screened a library of drugs either FDA-approved or in clinical trial using a library of patient-derived H3K27M-mutant diffuse midline glioma cell lines with cell viability as the outcome.

    Glioblastoma scRNAseq Shows Treatment-induced, Immune-dependent Rise In Mesenchymal Cancer Cells, and Structural Variants in Distal Neural Stem Cells

    Scientists used single-cell RNA-sequencing to analyze new and recurrent glioblastoma, and the nearby subventricular zone. They found four glioblastoma neural lineages were present in new and recurrent glioblastoma with an enrichment of the cancer mesenchymal lineage, immune cells, and reactive astrocytes in early recurrences.

    VCP Suppresses Proteopathic Seeding in Neurons

    Investigators performed a fluorescent cell sorting based genome-wide CRISPR-Cas9 screen in alpha-synuclein (αS) biosensors. αS and TDP-43 seeding activity under varied conditions was assessed using FRET/Flow biosensor cells or immunofluorescence for phosphorylated αS or TDP-43 in primary cultured neurons.

    Microglia/Macrophage-Derived Human CCL18 Promotes Glioma Progression via CCR8-ACP5 Axis Analyzed in Humanized Slice Model

    The authors studied the importance of CCL18, a cytokine expressed in human but not in rodent glioma-associated microglia/macrophages, as a modulator of glioma growth.

    Targeting NQO1/GPX4-Mediated Ferroptosis by Plumbagin Suppresses In Vitro and In Vivo Glioma Growth

    Plumbagin showed higher blood-brain barrier penetration ability than that of lapachol and shikonin and elicited significant growth inhibitory effects in vitro and in vivo.

    Abstract

    Suppression of the Hyaluronic Acid Pathway Induces M1 Macrophages Polarization via STAT1 in Glioblastoma

    Scientists observed that disrupting glioblastoma hyaluronic acid (HA) synthesis or blocking HA binding to its receptor CD44 on macrophages increased the proportion of M1 macrophages by upregulating SIRPα in macrophages,

    TFCP2, a Binding Protein of ATF3, Promotes the Progression of Glioma by Activating the Synthesis of Serine

    Researchers found that the expression of TFCP2 was upregulated in glioma and that TFCP2 promoted glioma cell growth and sphere formation.

    Retroviral Elements in Pathophysiology and as Therapeutic Targets for Amyotrophic Lateral Sclerosis

    Individuals with HIV-associated amyotrophic lateral sclerosis show a remarkable response to antiretroviral therapy; however, antiretroviral trials in ALS down-regulate HML-2 without ameliorating the disease.
