(Submitter supplied) Transcriptional targets of neurogenin (Ngnr1) were identified by over-expression of an inducible form of neurogenin in Xenopus ectodermal explants. The effects of co-expressing the nucleoprotein geminin on Ngnr1-dependent target gene transactivation were defined. Regulating the transition from lineage-restricted progenitors to terminally differentiated cells is a central aspect of nervous system development. more...

(Submitter supplied) Regulating the transition from lineage-restricted progenitors to terminally differentiated cells is a central aspect of nervous system development. Here, we investigated the role of the nucleoprotein Geminin in regulating neurogenesis at a mechanistic level during both Xenopus primary neurogenesis and mammalian neuronal differentiation in vitro. The latter work utilized both neural cells derived from embryonic stem and embryonal carcinoma cells in vitro and neural stem cells from mouse forebrain. more...

(Submitter supplied) The nucleoprotein Geminin (Gmnn) promotes neural cell fate acquisition of embryonic stem cells, while knockdown reduces the efficiency of neural gene activation. This occurs, at least in part, through Geminin’s ability to promote histone hyperacetylation at neural genes, to activate their expression. In mouse models in vivo, Geminin deficiency in the embryonic neural tube between embryonic days 8.5-10.5 also reduces the expression of genes controlling neural specification and/or differentiation, contributing to neural tube defects. more...

(Submitter supplied) Cell intrinsic factors that control neuroectoderm specification of early embryonic cells include the nucleoprotein Geminin (Gmnn) and the Zic family of zinc finger transcription factors. Gmnn modulates chromatin state to activate neural gene expression during neural cell fate acquisition, while Gmnn deficiency in the forming neural plate disrupts transcriptional programs that control neural cell specification, neural plate patterning and neurogenesis, resulting in neural tube defects. more...

(Submitter supplied) Formation of the complex vertebrate nervous system begins when pluripotent cells of the early embryo are directed to acquire a neural fate. Although cell intrinsic controls play an important role in this process, the molecular nature of this regulation is not well defined. Here we assessed the role for Geminin, a nuclear protein expressed in embryonic cells, in neural fate acquisition from mouse embryonic stem (ES) cells. more...

(Submitter supplied) The mechanisms that activate some genes while silencing others are critical to ensure precision in lineage specification as multipotent progenitors become restricted in cell fate. During neurodevelopment, these mechanisms are required to generate the wide variety of neuronal subtypes found in the nervous system. Here we report interactions between basic helix-loop-helix (bHLH) transcriptional activators and the transcriptional repressor PRDM13 that are critical for these processes during specification of dorsal spinal cord neurons. more...

(Submitter supplied) Zinc-finger genes Fezf1 and Fezf2 encode transcriptional repressors. Fezf1 and Fezf2 are expressed in the early neural stem/progenitor cells and control neuronal differentiation in mouse dorsal telencephalon. We compared gene expression profiles of rostral forebrains, which contain the telencephalon and the rostral part of the diencephalon, from embryonic day (E) 9.5, E10.5, and E12.5 wild-type control and Fezf1-/- Fezf2 -/- mouse embryos.

(Submitter supplied) Geminin cooperates with Polycomb to restrain multi-lineage commitment in the early embryo: Transient maintenance of a pluripotent embryonic cell population followed by the onset of multi-lineage commitment is a fundamental aspect of development. However, molecular regulation of this transition is not well characterized in vivo. Here we demonstrate that the nuclear protein Geminin is required to restrain commitment and spatially restrict mesoderm, endoderm, and non-neural ectoderm to their proper locations in the Xenopus embryo. more...

(Submitter supplied) A cardinal property of neural stem cells (NSCs) is their ability to adopt multiple fates upon differentiation. The epigenome is widely seen as a read-out of cellular potential and a manifestation of this can be seen in embryonic stem cells (ESCs), where promoters of many lineage-specific regulators are marked by a bivalent epigenetic signature comprising trimethylation of both lysine 4 and lysine 27 of histone H3 (H3K4me3 and H3K27me3, respectively). more...

(Submitter supplied) Post-translational modifications (PTMs) of histones exert fundamental roles in regulating gene expression. During development, groups of PTMs are constrained by unknown mechanisms into combinatorial patterns, which facilitate transitions from uncommitted embryonic cells into differentiated somatic cell lineages. Repressive histone modifications such as H3K9me3 or H3K27me3 have been investigated in detail, but the role of H4K20me3 in development is currently unknown. more...
