p107 regulates neural precursor cells in the mammalian brain
Here we show a novel function for Retinoblastoma family member, p107 in controlling stem cell expansion in the mammalian brain. Adult p107-null mice had elevated numbers of proliferating progenitor cells in their lateral ventricles. In vitro neurosphere assays revealed striking increases in the number of neurosphere forming cells from p107(-/-) brains that exhibited enhanced capacity for self-r...
متن کاملThe Snail Transcription Factor Regulates the Numbers of Neural Precursor Cells and Newborn Neurons throughout Mammalian Life
The Snail transcription factor regulates diverse aspects of stem cell biology in organisms ranging from Drosophila to mammals. Here we have asked whether it regulates the biology of neural precursor cells (NPCs) in the forebrain of postnatal and adult mice, taking advantage of a mouse containing a floxed Snail allele (Snailfl/fl mice). We show that when Snail is inducibly ablated in the embryon...
متن کاملMcl1 regulates the terminal mitosis of neural precursor cells in the mammalian brain through p27Kip1.
Cortical development requires the precise timing of neural precursor cell (NPC) terminal mitosis. Although cell cycle proteins regulate terminal mitosis, the factors that influence the cell cycle machinery are incompletely understood. Here we show in mice that myeloid cell leukemia 1 (Mcl1), an anti-apoptotic Bcl-2 protein required for the survival of NPCs, also regulates their terminal differe...
متن کاملPrion protein (PrPc) positively regulates neural precursor proliferation during developmental and adult mammalian neurogenesis.
The misfolding of the prion protein (PrP(c)) is a central event in prion diseases, yet the normal function of PrP(c) remains unknown. PrP(c) has putative roles in many cellular processes including signaling, survival, adhesion, and differentiation. Given the abundance of PrP(c) in the developing and mature mammalian CNS, we investigated the role of PrP(c) in neural development and in adult neur...
متن کاملp63 Regulates adult neural precursor and newly born neuron survival to control hippocampal-dependent Behavior.
The molecular mechanisms that regulate adult neural precursor cell (NPC) survival, and thus maintain adult neurogenesis, are not well defined. Here, we investigate the role of p63, a p53 family member, in adult NPC function in mice. Conditional ablation of p63 in adult NPCs or p63 haploinsufficiency led to reduced numbers of NPCs and newborn neurons in the neurogenic zones of the hippocampus an...
