    Morphological Diversification and Functional Maturation of Human Astrocytes in Glia-Enriched Cortical Organoid Transplanted in Mouse Brain

    Researchers demonstrated that induction of a gliogenic switch in a subset of progenitors enabled the rapid derivation of astroglial cells, which account for 25–31% of the cell population within 8–10 weeks of differentiation.

    APOE4 Genotype and Aging Impair Injury-Induced Microglial Behavior in Brain Slices, including toward Aβ, through P2RY12

    Using ex vivo confocal microscopy, investigators analyzed microglial dynamic behaviors in the entorhinal cortex and hippocampus CA1 of 6-, 12-, and 21-month-old mice APOE3 or APOE4 knock-in mice expressing GFP under the CX3CR1 promoter.

    LncRNA LUCAT1 Promotes Glioblastoma Progression by Enhancing HIF1α Activity

    lncRNAs induced by hypoxia in glioma stem-like cells (GSCs) were identified by RNAseq. LUCAT1 expression was assessed by qPCR, RNAseq, Northern blot, single molecule FISH in GSCs, and interrogated in IvyGAP, TCGA, and CGGA databases.

    Abstract

    HIF1α/ATF3 Partake PGK1 K191/K192 Succinylation by Modulating P4HA1/Succinate Signaling in Glioblastoma

    The authors used ChIP assays to uncover the crosstalk between HIF1α and ATF3 and their roles in P4HA1 regulation. Protein degradation analysis, LC-MS/MS, and in vitro succinate production assays were performed to examine the effect of protein succinylation on glioblastoma pathology.

    Single Neurons in the Thalamus and Subthalamic Nucleus Process Cardiac and Respiratory Signals in Humans

    Researchers investigated the activity of single neurons related to cardiac and respiratory functions in three subcortical regions: ventral intermedius nucleus and ventral caudalis nucleus of the thalamus, and subthalamic nucleus.
