[PDF][PDF] Ascl1 coordinately regulates gene expression and the chromatin landscape during neurogenesis

AASF Raposo, FF Vasconcelos, D Drechsel, C Marie… - Cell reports, 2015 - cell.com
The proneural transcription factor Ascl1 coordinates gene expression in both proliferating
and differentiating progenitors along the neuronal lineage. Here, we used a cellular model of …

[PDF][PDF] Capu and Spire assemble a cytoplasmic actin mesh that maintains microtubule organization in the Drosophila oocyte

K Dahlgaard, AASF Raposo, T Niccoli, D St Johnston - Developmental cell, 2007 - cell.com
Mutants in the actin nucleators Cappuccino and Spire disrupt the polarized microtubule
network in the Drosophila oocyte that defines the anterior-posterior axis, suggesting that …

[PDF][PDF] From stem cell to embryo without centrioles

NR Stevens, AASF Raposo, R Basto, D St Johnston… - Current Biology, 2007 - cell.com
Centrosome asymmetry plays a key role in ensuring the asymmetric division of Drosophila
neural stem cells (neuroblasts [NBs]) and male germline stem cells (GSCs) [1–3]. In both …

Zeb1 controls neuron differentiation and germinal zone exit by a mesenchymal-epithelial-like transition

…, K Kessler, T Ong, P Rosmaninho, AASF Raposo… - Elife, 2016 - elifesciences.org

morphologically via neuronal polarity programs. Despite discovery of polarity pathways …

[PDF][PDF] PAD2-mediated citrullination contributes to efficient oligodendrocyte differentiation and myelination

…, M Klingener, M Varas-Godoy, AASF Raposo… - Cell Reports, 2019 - cell.com
Citrullination, the deimination of peptidylarginine residues into peptidylcitrulline, has been
implicated in the etiology of several diseases. In multiple sclerosis, citrullination is thought to …

[PDF][PDF] MyT1 counteracts the neural progenitor program to promote vertebrate neurogenesis

FF Vasconcelos, A Sessa, C Laranjeira, AASF Raposo… - Cell reports, 2016 - cell.com
The generation of neurons from neural stem cells requires large-scale changes in gene
expression that are controlled to a large extent by proneural transcription factors, such as Ascl1. …

Zeb1 potentiates genome‐wide gene transcription with Lef1 to promote glioblastoma cell invasion

…, V Piscopo, V Teixeira, AASF Raposo… - The EMBO …, 2018 - embopress.org
Glioblastoma is the most common and aggressive brain tumor, with a subpopulation of stem‐like
cells thought to mediate its recurring behavior and therapeutic resistance. The epithelial…

What are the roles of microRNAs at the mammalian synapse?

…, JE Heraud, L Schoderboeck, AASF Raposo… - Neuroscience …, 2009 - Elsevier
The modification of neuronal connections in response to stimuli is believed to be the basis
of long-term memory formation. It is currently accepted that local protein synthesis critically …

[HTML][HTML] A multi-resource data integration approach: identification of candidate genes regulating cell proliferation during neocortical development

…, F Freudenberg, Y Wang, AASF Raposo… - Frontiers in …, 2014 - frontiersin.org
Neurons of the mammalian neocortex are produced by proliferating cells located in the
