Project description:Borna disease virus (BoDV-1) is a highly neurotropic RNA virus, which causes neurobehavioral disturbances such as abnormal social activities and memory impairment. In this study, we investigated the effects of BoDV-1 infection on neuronal differentiation and transcriptome of differentiated neuronal cells using persistently BoDV-1-infected SH-SY5Y (SB) cells. Differentiated neuronal cells exhibited transcriptomic changes of genes related to neurite outgrowth and antiviral immune system.

Project description:Gene duplication enables the emergence of new functions by lowering the general evolutionary pressure. Previous studies have highlighted the role of specific paralog genes during cell differentiation, e.g., in chromatin remodeling complexes. It remains unexplored whether similar mechanisms extend to other biological functions and whether the regulation of paralog genes is conserved across species. Here, we analyze the expression of paralogs across human tissues, during development and neuronal differentiation in fish, rodents and humans. While ~80% of paralog genes are co-regulated, a subset of paralogs shows divergent expression profiles, contributing to variability of protein complexes. We identify 78 substitutions of paralog eggNOG pairs that occur during neuronal differentiation and are conserved across species. Among these, we highlight a substitution between the paralogs Sec23a and Sec23b subunits of the COPII complex. Altering the ratio between these two genes via silencing-RNA knockdown was able to influence neuronal differentiation in different ways. We propose that remodeling of the vesicular transport system via paralog substitutions is an evolutionary conserved mechanism enabling neuronal differentiation.

Altering the ratio between these two genes via RNAi-mediated knockdown is sufficient to influence the differentiation of immature neuron. We propose that remodeling of the vesicular transport system via paralog substitutions is an evolutionary conserved mechanism enabling neuronal differentiation.

Project description: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.
