In the developing cerebral cortex, neurons are born on a predictable schedule. Here we show in mice that the essential timing mechanism is programmed within individual progenitor cells, and its expression depends solely on cell-intrinsic and environmental factors generated within the clonal lineage. Multipotent progenitor cells undergo repeated asymmetric(More)
The Drosophila protein Groucho is involved in the regulation of cell-determination events during insect neurogenesis and segmentation. A group of mammalian proteins, referred to as transducin-like Enhancer of split (TLE) 1 through 4, share with Groucho identical structures and molecular properties. The aim was to determine whether individual TLE proteins(More)
The mechanisms that regulate the acquisition of distinctive neuronal traits in the developing nervous system are poorly defined. It is shown here that the mammalian runt-related gene Runx1 is expressed in selected populations of postmitotic neurons of the embryonic central and peripheral nervous systems. These include cholinergic branchial and visceral(More)
Microglia are the immune cells of the nervous system, where they act as resident macrophages during inflammatory events underlying many neuropathological conditions. Microglia derive from primitive myeloid precursors that colonize the nervous system during embryonic development. In the postnatal brain, microglia are initially mitotic, rounded in shape(More)
Glioblastoma (GBM) is the most common and deadly malignant brain cancer, with a median survival of <2 years. GBM displays a cellular complexity that includes brain tumour-initiating cells (BTICs), which are considered as potential key targets for GBM therapies. Here we show that the transcription factors FOXG1 and Groucho/TLE are expressed in poorly(More)
The TLE proteins are the mammalian homologues of Groucho, a member of the Drosophila Notch signaling pathway. Notch signaling controls the differentiation of a variety of tissues in invertebrates and vertebrates. We are investigating the role of the TLE genes during mammalian development. We show that TLE 1 and TLE 3 are expressed during a number of(More)
Neurogenesis requires factors that regulate the decision of dividing progenitors to leave the cell cycle and activate the neuronal differentiation program. It is shown here that the murine runt-related gene Runx1 is expressed in proliferating cells on the basal side of the olfactory epithelium. These include both Mash1+ olfactory receptor neuron (ORN)(More)
Aristaless-related homeobox gene (ARX) is an important paired-type homeobox gene involved in the development of human brain. The ARX gene mutations are a significant contributor to various forms of X-chromosome-linked mental retardation with and without additional features including epilepsy, lissencephaly with abnormal genitalia, hand dystonia or autism.(More)
Krüppel-like factor 7 (KLF7) belongs to the large family of KLF transcription factors, which comprises at least 17 members. Within this family, KLF7 is unique since its expression is strictly restricted within the nervous system during development. We have previously shown that KLF7 is required for neuronal morphogenesis and axon guidance in selected(More)
