Cue-Polarized Transport of β-actin mRNA Depends on 3′UTR and Microtubules in Live Growth Cones

open access: yesFrontiers in Cellular Neuroscience, 2018
Guidance cues trigger fast responses in axonal growth cones such as directional turning and collapse that require local protein synthesis. An attractive cue-gradient, such as Netrin-1, triggers de novo synthesis of β-actin localized to the near-side ...

Post-mortem Characterisation of a Case With an ACTG1 Variant, Agenesis of the Corpus Callosum and Neuronal Heterotopia

open access: yesFrontiers in Physiology, 2019
Cytoplasmic Actin Gamma 1 (ACTG1) gene variant are autosomal dominant and can cause CNS anomalies (Baraitser Winter Malformation Syndrome; BWMS). ACTG1 anomalies in offspring include agenesis of the corpus callosum (ACC) and neuronal heterotopia which ...

Semaphorin-3A Promotes Degradation of Fragile X Mental Retardation Protein in Growth Cones via the Ubiquitin-Proteasome Pathway

open access: yesFrontiers in Neural Circuits, 2020
Fragile X mental retardation protein (FMRP) is an RNA-binding protein that regulates local translation in dendrites and spines for synaptic plasticity. In axons, FMRP is implicated in axonal extension and axon guidance.

Participation of L-Lactate and Its Receptor HCAR1/GPR81 in Neurovisual Development

open access: yesCells, 2021
During the development of the retina and the nervous system, high levels of energy are required by the axons of retinal ganglion cells (RGCs) to grow towards their brain targets.

A nonlocal supercritical Neumann problem [PDF]

open access: yes, 2019
We establish existence of positive non-decreasing radial solutions for a nonlocal nonlinear Neumann problem both in the ball and in the annulus. The nonlinearity that we consider is rather general, allowing for supercritical growth (in the sense of ...

Robo2 acts in trans to inhibit Slit-Robo1 repulsion in pre-crossing commissural axons

open access: yeseLife, 2015
During nervous system development, commissural axons cross the midline despite the presence of repellant ligands. In Drosophila, commissural axons avoid premature responsiveness to the midline repellant Slit by expressing the endosomal sorting receptor ...

Translational regulation in growth cones [PDF]

open access: yesCurrent Opinion in Genetics & Development, 2011
Axonal growth cones (GCs) steer in response to extrinsic cues using mechanisms that include local protein synthesis. This adaptive form of gene regulation occurs with spatial precision and depends on subcellular mRNA localisation. Recent genome-wide studies have shown unexpectedly complex and dynamically changing mRNA repertoires in growing axons and ...

miR-182 Regulates Slit2-Mediated Axon Guidance by Modulating the Local Translation of a Specific mRNA

open access: yesCell Reports, 2017
During brain wiring, cue-induced axon behaviors such as directional steering and branching are aided by localized mRNA translation. Different guidance cues elicit translation of subsets of mRNAs that differentially regulate the cytoskeleton, yet little ...

The Role of Apoptotic Signaling in Axon Guidance

open access: yesJournal of Developmental Biology, 2018
Navigating growth cones are exposed to multiple signals simultaneously and have to integrate competing cues into a coherent navigational response. Integration of guidance cues is traditionally thought to occur at the level of cytoskeletal dynamics ...

Giant ankyrin-B mediates transduction of axon guidance and collateral branch pruning factor sema 3A

open access: yeseLife, 2021
Variants in the high confident autism spectrum disorder (ASD) gene ANK2 target both ubiquitously expressed 220 kDa ankyrin-B and neurospecific 440 kDa ankyrin-B (AnkB440) isoforms.
