Project description:Waardenburg syndrome (WS) is a autosomal dominant inherited disorder characterized by sensorineural hearing loss (SNHL) and pigment abnormalities. SOX10 is one of its main pathogenicity genes. In vitro generation of patient-specific induced pluripotent stem cells (iPSCs) is an effective approach for exploring the mechanisms of human disease. Here, we established an iPSCs from a WS patient with SOX10 mutation and differentiated it into induced neural crest cells (NCCs), the key cell type involves in inner ear development. Compared with control-derived iPSCs, the SOX10 mutant iPSCs showed significantly decreased efficiency of development and differentiation potential at the stage of NCCs. We then performed high-throughput RNA-seq and examined the transcriptional misregulation at each stage. The transcriptome analysis differentiated NCCs reveals widespread gene expression changes and the differentially expressed genes(DEGs) were enriched with gene ontology (GO) of neuron migration, skeletal system development, multicellular organism development, which indicate the important role of SOX10 plays in the differentiation of NCCs. It's worth noting that, a significant enrichment among the nominal DEGs for genes implicated in inner ear development was found, as well as several genes related to the inner ear morphogenesis. Based on protein-protein interaction（PPI）net work, we selected four candidate genes that may be regulated by SOX10 in inner ear development: BMP2, LGR5, GBX2 and GATA3. In conclusion, the SOX10 deficiency in this WS patient has a significant impact on the gene expression patterns during the development of NCCs. The DEGs most significantly enriched the inner ear development and morphogenesis could help explain the underlying basis for the inner ear malformation seen in WS patient.

Project description:Here, control human pluripotent stem cells (hiPSCs) and SOX10 knockout (SOX10 KO) hiPSCs were induced to differentiate to neural crest stem cells (NCSCs). We sequenced mRNA samples of differentiated cells at day 7 during NCSC differentiation to generate the gene expression profiles of these cells.

Project description:Background: The goal of this study was to determine the transcriptional consequences of norepinephrine transporter (NET) gene deletion in noradrenergic neuron differentiation. The norepinephrine transporter (NET) is the target of powerful mind-altering substances, such as tricyclic antidepressants and the drug of abuse, cocaine. NET function in adult noradrenergic neurons of the peripheral and central nervous systems is that of a scavenger that internalizes norepinephrine from the synaptic cleft. By contrast, norepinephrine (NE) transport has a different role in embryogenesis. It promotes differentiation of neural crest cells and locus ceruleus progenitors into noradrenergic neurons, whereas NET inhibitors, such as the tricyclic antidepressant desipramine and the drug of abuse, cocaine, inhibit noradrenergic differentiation. While NET structure und regulation of NET function is well described, little is known about downstream targets of NE transport. Results: We have determined by long serial analysis of gene expression (LongSAGE) the gene expression profiles of in vitro differentiating wild type and norepinephrine transporter-deficient (NETKO) neural crest derivatives. Comparison analyses with the wild type library (GSM 105765) have identified a number of important differentially expressed genes, including genes relevant to noradrenergic neuron differentiation and to the phenotype of NETKO mice. Furthermore we have identified novel differentially expressed genes. Conclusions: Loss of NET function during embryonic development deregulates signaling pathways that are critically involved in neural crest formation and noradrenergic neuron differentiation. The library was constructed from total RNA of 60 neural crest culture at culture day 7. The neural tubes were dissected from E9.5 embryos that lack the norepinephrine transporter gene.

Project description:Hirschsprung’s disease (HSCR) is a congenital disease which is characterized by the reduction or absence of neurons and glial cells in the enteric nervous system (ENS). Failure of neural crest cells (NCCs) to colonize the gut during the embryonic development has been considered as one of the possible causes of the disease. In this study, the migration and gene expression of sacral NCCs from the spontaneous mouse mutant Dominant megacolon (Dom) which is a HSCR animal model expressing a mutated transcription factor Sox10, were analyzed in order to identify candidate genes which may possibly affect the NCC migration in the mutant.

Project description:The neural crest is a dynamic progenitor cell population that arises at the border of neural and non-neural ectoderm. The inductive roles of FGF, Wnt, and BMP at the neural plate border are well established, but the signals required for subsequent neural crest development remain poorly characterized. Here, we conducted a screen in primary zebrafish embryo cultures for chemicals that decrease neural crest formation, as read out by crestin:EGFP expression. We found that the natural product caffeic acid phenethyl ester (CAPE) disrupts neural crest gene expression, migration, and melanocytic differentiation by reducing Sox10 activity. CAPE inhibits PI3K/Akt signaling specifically in FGF-stimulated cells, and neural crest defects in CAPE-treated embryos are suppressed by constitutively active Akt1. Inhibition of Akt activity by constitutively active PTEN similarly decreases crestin expression and Sox10 activity. Our study has identified Akt as a novel intracellular pathway required for neural crest development.
