    Enhanced Cortical Neural Stem Cell Identity Through Short SMAD and WNT Inhibition in Human Cerebral Organoids Facilitates Emergence of Outer Radial Glial Cells

    Researchers reported that a short and early dual SMAD and WNT inhibition course was necessary and sufficient to establish robust and lasting cortical organoid neural stem cell (NSC) identity, efficiently suppressing non-cortical NSC fates.

    TWIST1 Methylation by SETD6 Selectively Antagonizes LINC-PINT Expression in Glioma

    The authors showed that TWIST1 was methylated on lysine-33 at chromatin by SET domain-containing protein 6 (SETD6), a methyltransferase with expression levels correlating with poor survival in glioma patients.

    MIF Homolog D-Dopachrome Tautomerase (D-DT/MIF-2) Does Not Inhibit Accumulation and Toxicity of Misfolded SOD1

    Scientists demonstrated that macrophage migration inhibitory factor (MIF), a multifunctional protein with cytokine/chemokine and chaperone-like activity, inhibited the accumulation and aggregation of misfolded SOD1.
