    Cholesterol and Matrisome Pathways Dysregulated in Astrocytes and Microglia

    Researchers investigated the effects of apolipoprotein E ε4 (APOE4) on brain cell types derived from population and isogenic human induced pluripotent stem cells, post-mortem brain, and APOE targeted replacement mice.

    Temozolomide-Induced Guanine Mutations Create Exploitable Vulnerabilities of Guanine-Rich DNA and RNA Regions in Drug-Resistant Gliomas

    Scientists reported that temozolomide-resistant glioblastoma has guanine (G) mutations that disrupted the G-rich DNA G-quadruplex and splice sites that lead to deregulated alternative splicing.

    The 22q11.2 Region Regulates Presynaptic Gene-Products Linked to Schizophrenia

    Investigators showed that upon induced pluripotent stem cells’ differentiation into neural progenitor cells, the deletion of 22q11.2 acted in trans to alter the abundance of transcripts associated with risk for neurodevelopmental disorders including autism.

    Spatiotemporal Analysis of Glioma Heterogeneity Reveals COL1A1 as an Actionable Target to Disrupt Tumor Progression

    The authors reported that the inhibition of Col1a1 eliminated oncostreams, reprogramed the malignant histopathological phenotype, reduced expression of the mesenchymal associated genes, induced changes in the tumor microenvironment, and prolonged animal survival.

    Loss of Stathmin-2, a Hallmark of TDP-43-Associated ALS, Causes Motor Neuropathy

    Scientists reported that constitutive stathmin-2 loss resulted in early-onset sensory and motor neuropathy featuring impaired motor behavior and dramatic distal neuromuscular junction denervation of fast-fatigable motor units.

    ALS-Linked KIF5A ΔExon27 Mutant Causes Neuronal Toxicity through Gain-of-Function

    Researchers performed a comprehensive analysis of ΔExon27 at the single-molecule, cellular, and organism levels. Results showed that ΔExon27 was prone to form cytoplasmic aggregates and was neurotoxic.

    Genomic, Transcriptomic, and Metabolomic Profiles of hiPSC-Derived Dopamine Neurons from Clinically Discordant Brothers with Identical PRKN Deletions

    Scientists differentiated human-induced pluripotent stem cells (hiPSCs) derived from the two brothers into mesencephalic neural precursor cells and early postmitotic dopaminergic neurons and performed whole exome sequencing and transcriptomic and metabolomic analyses.

    Liver Glycogen Phosphorylase Is Upregulated in Glioblastoma and Provides a Metabolic Vulnerability to High Dose Radiation

    Investigators reported that knockdown of the glycogen phosphorylase liver isoform, but not the brain isoform, decreased clonogenic growth and survival of glioblastoma cell lines and sensitized them to ionizing radiation doses.

    Upregulation of β-Catenin Due to Loss of miR-139 Contributes to Motor Neuron Death in Amyotrophic Lateral Sclerosis

    The authors explored the misexpression of miRNAs in an induced pluripotent stem cell-based disease model of FUS ALS.

    TTF1 Suppresses Neuroblastoma Growth and Induces Neuroblastoma Differentiation by Targeting TrkA and the miR-204/TrkB Axis

    Researchers reported that TTF1 suppressed proliferation, migration, and invasion of neuroblastoma (NB) cells, while induced cell cycle arrest, apoptosis, and autophagy of NB cells by regulating TrkA and the miR-204-TrkB axis.

    CDC20 Regulates Sensitivity to Chemotherapy and Radiation in Glioblastoma Stem Cells

    The authors reported that CDC20 knockdown did not increase temozolomide- and radiation-induced DNA damage, or alter DNA damage repair, but rather promoted cell death through accumulation of the pro-apoptotic protein, Bim.

    Targeting CXCR4 to Suppress Glioma-Initiating Cells and Chemoresistance in Glioma

    Scientists reported that C-X-C motif chemokine receptor 4 (CXCR4) mediated the upregulation of Kruppel like factor 5, a zinc-finger-containing transcription factor, to facilitate the proliferation of glioma initiating cells.

    Abstract

    Transcription Factor-Based Direct Conversion of Human Fibroblasts to Functional Astrocytes

    Expression of the minimal combination of Sox9 and Nfib generated induced astrocytes with molecular, phenotypic, and functional properties resembling primary human astrocytes.
