    Extension of mRNA poly(A) Tails and 3′UTRs During Neuronal Differentiation Exhibits Variable Association with Post-Transcriptional Dynamics

    Researchers employed poly(A) tail sequencing, mRNA sequencing, ribosome profiling, and small RNA sequencing to explore the functional relationship between mRNA abundance, translation, poly(A) tail length, alternative polyadenylation (APA), and miRNA expression in an in vitro model of neuronal differentiation.

    Abstract

    ArhGAP11A Mediates Amyloid-β Generation and Neuropathology in an Alzheimer’s Disease-Like Mouse Model

    Researchers found that the levels of ArhGAP11A, a Ras homology GTPase-activating protein, significantly increased in patients with Alzheimer’s disease and amyloid precursor protein/presenilin-1 mice.

    G9a Inhibition Promotes Neuroprotection through GMFB Regulation in Alzheimer’s Disease

    Investigators observed the induction of neuronal plasticity and a reduction of neuroinflammation after G9a inhibitor treatment, and these neuroprotective effects were reverted by the pharmacological inhibition of glia maturation factor β (GMFB) in mice and cell cultures.

    Exosomal miR-6733-5p Mediates Cross-Talk Between Glioblastoma Stem Cells and Macrophages and Promotes Glioblastoma Multiform Progression Synergistically

    Glioblastoma stem cells (GSCs)-derived exosomal miR-6733-5p induced macrophage M2 polarization of tumor-associated macrophages by positively targeting IGF2BP3 to activate the AKT signaling pathway, which further facilitated the self-renewal and stemness of GSCs.
