A quantitative map of proteome dynamics during neuronal differentiation

ABSTRACT: Neuronal differentiation is a multistep process that shapes and re-shapes neurons by progressing through several typical stages, including axon outgrowth, dendritogenesis and synapse formation. To systematically profile protein expression during neuronal differentiation we have used cultured hippocampal neurons at different developmental stages in combination with triplex stable isotope dimethyl labeling technique coupled to high-resolution tandem mass spectrometry (LC-MS/MS). In total >1,500 proteins show more than two-fold expression changes during the different developmental steps, indicating extensive remodeling of the neuron proteome during differentiation. To demonstrate the strength of our resource, we focused on neural cell adhesion molecule 1 (NCAM1) as a regulator for dendritic outgrowth during neuronal development. The transmembrane isoform of NCAM1, NCAM180, is strongly upregulated during dendrite outgrowth, highly enriched in dendritic growth cones and interacts with a large variety of actin binding proteins. Inducing actin polymerization rescues the NCAM1 knockdown phenotype, suggesting that NCAM180 stimulates dendritic arbor development by promoting actin filament growth at the dendritic growth cone. Thus, our quantitative map of neuronal proteome dynamics will serve as a rich resource for further analyses of neurodevelopmental regulated processes.

Neuronal differentiation is a multistep process that shapes and re-shapes neurons by progressing through several typical stages, including axon outgrowth, dendritogenesis, and synapse formation. To systematically profile proteome dynamics throughout neuronal differentiation, we took cultured rat hippocampal neurons at different developmental stages and monitored changes in protein abundance using a combination of stable isotope labeling and high-resolution liquid chromatography-tandem mass spect ...[more]

Project description:Neurogenesis is a pro-survival process that comprises of dendritic and axonal growth, synaptogenesis, synaptic and neuronal pruning. These complex processes are determined by temporal gene expression during development, which is in turn tightly regulated by long non-coding RNAs and microRNAs. In this study, we investigated the processes implicated in the maturation of primary neuronal cultures based on RNA expression profiling. Correlation between neuron specific gene ontologies of mRNA and non-coding RNAs identified direct regulation of axonogenesis and dendritogenesis. Temporally regulated mRNA and their associated long non-coding RNAs were significantly overrepresented in proliferation and differentiation associated signalling, cell adhesion molecules and neurotrophin signalling pathways during neuronal maturation. Long non-coding RNAs associated with Axin2, Cntn1, Ncam1, Negr1, Ntrk2, Nrxn1 and Sh2b3 displayed an inverse expression profile to their mRNA whereas long non-coding RNA -mRNA pairs for Kit, Prkcb and Ralgds displayed similar expression profiles. These genes were also predicted targets of the altered miRNAs, miR-124, -128, -129-5p, -203, -218, -290-5p, -326, -329, -377 and -495. These microRNAs particularly regulate the cell adhesion molecules, Cntn1, Ncam1, Negr1 and Nrxn1 that determine axonogenesis and dendritogenesis, supporting the observed co-regulation of these biological processes by non-coding RNAs. Verification of expression of these long non-coding RNA-mRNA pairs in an in vitro model of ischemic-reperfusion injury showed an inverse expression profile, thus confirming their role(s) in maintenance of the neuronal structure and function. This neuronal transcriptome (mRNAs, lncRNAs, miRNAs) is in turn orchestrated by C/EBPM-NM-1/M-NM-2 transcription factors and CTCF, thereby governing intricate control of neuronal development. microRNA expression profiling of maturing primary cortical neurons from E15 mouse embryos.

Project description:Mind bomb 1 (Mib1) is an E3 ubiquitin-ligase that is essential for overall metazoan development, including multiple stages of neuronal development. It is located in puncta throughout neurons, including near post synaptic densities (PSD), and has been shown to participate in several signaling pathways via its E3 ligase catalytic activity. The most well-characterized of these is the Notch signaling pathway, in which Mib1 facilitates Delta/Serrate/LAG-2 (DSL) ligand endocytosis and activation, allowing cell-cell communication to determine neuronal versus glial cell fate. This, however, is not the limit of Mib1 activity in the developing nervous system, as it also contributes to cell polarity, neurite outgrowth, and long-term potentiation (LTP), but it has not been demonstrated to affect dendritic spine development. We therefore sought to comprehensively characterize the Mib1 interactome and study its potential function in dendritic spine morphogenesis. We utilized a novel sequential elution method from Mib1 affinity purification to recover Mib1 binding proteins with both deep coverage and the ability to distinguish between high affinity binding partners from low affinity binding partners. This procedure revealed 837 potential binding partners, distinguished 72 from these as very-high confidence, and a further 387 as high confidence of interaction. Included in these were many proteins previously demonstrated to interact with Mib1, as well as 5 proteins of particular interest to us: Usp9x, a deubiquitinase; alpha-, beta-, and delta-catenins; regulators of Wnt signaling; and CDKL5, which is mutated in EIEE2, a severe form of mental retardation. We demonstrated that Mib1 downregulates CDKL5, limits its effects on dendritic spine outgrowth, and inhibits spine outgrowth itself. These data further elaborate upon the signaling networks and biological functions influenced by this critical protein and expand our understanding of the signaling networks involved in neuronal development.
