EGFR Mutation-Induced Alternative Splicing of Max Contributes to Growth of Glycolytic Tumors in Brain Cancer
Heterogeneous nuclear ribonucleoprotein (HnRNP)A1 promotes splicing of a transcript encoding the Myc-interacting partner Max, generating Delta Max, an enhancer of Myc-dependent transformation. Scientists report that Delta Max is shown to promote glioma cell proliferation in vitro and augment EGFRvIII expressing glioblastoma growth in vivo. [Cell Metab] Abstract | Graphical Abstract

Abnormal Neuronal Differentiation and Mitochondrial Dysfunction in Hair Follicle-Derived Induced Pluripotent Stem Cells of Schizophrenia Patients
Induced pluripotent stem cells (iPSCs) from three schizophrenia patients and from two controls were reprogrammed from hair follicle keratinocytes, because of their accessibility and common ectodermal origin with neurons. iPSCs were differentiated into Pax6+/Nestin+ neural precursors and then further differentiated into β3-Tubulin+/tyrosine hydroxylase+/DAT+ dopaminergic neurons. [Mol Psychiatr] Abstract

Neurulation and Neurite Extension Require the Zinc Transporter ZIP12 (slc39a12)
Scientists confirmed that ZIP12 is a Zn2+ uptake transporter with a conserved pattern of high expression in the mouse and Xenopus nervous system. Mouse neurons and Neuro-2a cells produce fewer and shorter neurites after ZIP12 knockdown without affecting cell viability. [Proc Natl Acad Sci USA] Abstract

Cytomegalovirus Contributes to Glioblastoma in the Context of Tumor Suppressor Mutations
To study the controversial role of cytomegalovirus (CMV) in glioblastoma, researchers assessed the effects of murine CMV (MCMV) perinatal infection in a GFAP-cre; Nf1loxP/+; Trp53−/+ genetic mouse model of glioma (Mut3 mice). MCMV infection increased phosphorylated STAT3 (p-STAT3) levels in neural stem cells (NSC) harvested from Mut3 mice subventricular zone, and, in vivo, there was increased p-STAT3 in NSCs in MCMV-infected compared with control mice. [Cancer Res] Abstract

Ascl1/Mash1 Promotes Brain Oligodendrogenesis during Myelination and Remyelination
Researchers investigated the contribution of Ascl1 to oligodendrocyte development and remyelination in the postnatal cortex. During the neonatal period, Ascl1 expression was detected in progenitors of the cortical subventricular zone and in cortical oligodendrocyte precursor cells. [J Neurosci] Abstract

Recovery from Experimental Parkinsonism by Semaphorin-Guided Axonal Growth of Grafted Dopamine Neurons
The authors asked whether intranigral transplantation of dopamine (DA) neurons, combined with either degradation of chondroitin sulphate proteoglycans or with grafts of Semaphorin 3-expressing cells, towards the striatum, is effective in establishing a new nigrostriatal dopaminergic pathway in rats with unilateral depletion of DA neurons. They found depolarization-induced DA release in dorsal striatum, DA axonal projections from substantia nigra to striatum, and concomitant behavioral improvement in Semaphorin 3-treated animals. [Mol Ther] Abstract

Viral Delivery of Antioxidant Genes as a Therapeutic Strategy in Experimental Models of Amyotrophic Lateral Sclerosis
Lentiviral vectors expressing either PRDX3 or NRF2 genes were tested in the motor neuronal-like NSC34 cell line, and in the amyotrophic lateral sclerosis tissue culture model, NSC34 cells expressing the human SOD1G93A mutation. The NSC34 SOD1G93A cells overexpressing either PRDX3 or NRF2 showed a significant decrease in endogenous oxidation stress levels by 40 and 50% respectively compared with controls, whereas cell survival was increased by 30% in both cases. [Mol Ther] Abstract

Amyloid β Peptides Promote Autophagy-Dependent Differentiation of Mouse Neural Stem Cells
Investigators addressed the role of different amyloid β (Aβ) fragments in neural stem cell proliferation and differentiation, and investigated whether autophagy is involved in Aβ-induced alterations of neural fate. Their results demonstrated that neuronal and glial-specific protein markers are significantly induced by both Aβ1-40 and Aβ1-42. [Mol Neurobiol] Abstract

Nitric Oxide Inhibits CXCL12 Expression in Neuroinflammation
The influence of nitric oxide (NO) on C-X-C motif chemokine ligand 12 (CXCL12) in the inflamed central nervous system was investigated. Excess expression of inducible NO synthase was inversely correlated to CXCL12 gene expression in spinal cord homogenates of rats immunized to develop experimental autoimmune encephalomyelitis. NO inhibited gene expression of CXCL12 in astrocytes and endothelial cells in vitro. [Immunol Cell Biol] Abstract

Effects of Epidermal Growth Factor and Basic Fibroblast Growth Factor on the Proliferation and Osteogenic and Neural Differentiation of Adipose-Derived Stem Cells
The authors illustrated that low concentrations of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) increase the proliferative ability of adipose-derived mesenchymal stem cells (ASCs) and induce the typical spindle-shaped cell morphology. EGF and bFGF added to medium promoted neural lineage differentiation and impaired the mesodermal differentiation ability of ASCs. [Cell Reprogram] Abstract

Transcriptional Differences between Normal and Glioma-Derived Glial Progenitor Cells Identify a Core Set of Dysregulated Genes
Scientists used A2B5-based sorting to extract tumorigenic glial progenitor cells (GPCs) from human gliomas spanning World Health Organization grades II-IV. Messenger RNA profiling identified a cohort of genes that distinguished A2B5+ glioma tumor progenitor cells (TPCs) from A2B5+ GPCs isolated from normal white matter. A core set of genes and pathways was substantially dysregulated in A2B5+ TPCs, which included the transcription factor SIX1 and its principal cofactors, EYA1 and DACH2. [Cell Rep]

Aging Stem and Progenitor Cells: Implications for Rejuvenation of the Central Nervous System

The prospect of meaningful rejuvenation of the central nervous system (CNS) has seemed an impossible goal; however, advances in stem cell science are beginning to challenge this assumption. The authors outline these advances with a focus on aging and rejuvenation of key endogenous stem and progenitor cell compartments in the CNS. [Development] Full Article
