Project description:Although proper tongue development is relevant to other structures in the craniofacial region, the molecular details of muscle development in tongue remain poorly understood. Here, we report that pregnant mice treated with retinoic acid (+RA) produce embryos with tongue malformation and a cleft palate. Histological analyses revealed that at E14.5, the tongues of +RA fetuses failed to descend and flatten. Ultrastructural analysis showed that at perinatal stage E18.5, the myofilaments failed to form normal structures of sarcomeres, and arranged disorderly in the genioglossus. The proliferation and levels of myogenic determination markers (Myf5 and MyoD) and myosin in the genioglossus were profoundly reduced. Wnt5a and Camk2d expressions were down-regulated, while levels of Tbx1, Ror2, and PKCδ were up-regulated in the tongues of +RA fetuses. In mock- and Wnt5a-transfected C2C12 (Wnt5a-C2C12) cells, Wnt5a overexpression impaired proliferation, and maintained Myf5 at a relative high level after RA treatment. Furthermore, Wnt5a overexpression positively correlated with levels of Camk2d and Ror2 in C2C12 cells after RA exposure. These data support the hypothesis that the Wnt5a/CaMKII pathway is directly involved in RA-induced hypoplasia and disorder of tongue muscles.

Project description:The tongue is a unique muscular organ situated in the oral cavity where it is involved in taste sensation, mastication and articulation. As a barrier organ, which is constantly exposed to environmental pathogens,the tongue isexpected to host animmune cell network ensuringlocal immune defence. However, the composition and the transcriptional landscape of the tongue immune system are currently not completely defined. Here we characterised the tissue-resident immune compartment of the murine tongue during development, health anddisease, combining single cell RNA-sequencing with in situ immunophenotyping. We identified distinct local immune cell populations and described two specific subsets of tongue-resident macrophages occupying discrete anatomical niches. Cx3cr1+macrophages were located specifically in the highly innervated lamina propria beneath the tongue epidermis and at times in close proximity to fungiform papillae.Folr2+ macrophages were detected in deeper muscular tissue. The two macrophage subsets originate from a common proliferative precursor during early postnatal development and responded differently to systemic LPSin vivo. Our description of the under-investigated tongue immune system sets a starting point to facilitate research on tongue immune-physiology and pathology including cancer and taste disorders.

Project description:Tongue squamous cell carcinoma is a tumour type with rather low five year survival, around 60%. The poor survival rate has been ascribed to late detection, a high frequency of locoregional recurrence, the occurrence of secondary primary tumours and death due to comorbidity. One reason for development of recurrence is thought to be the existence of transformed cells in areas adjacent to the primary tumour, cancerization field effect. The aim of this study was to map the changes in the tumour free tongue tissue adjacent to tongue tumours compared with healthy control tongue tissue to better understand the cancerization field effect. Tissue biopsies were collected from tumour (T) and tumour free tissue adjacent to the tumour (TF) from patients with tongue squamous cell carcinoma. Control tissue was collected from latter border of the tongue of tumour free healthy volunteers (C). All samples were homogenized and RNA was extracted. The RNA was biotin labelled and run on Illumina HT-12 bead chip array.

Project description:The tongue is a heavily innervated and vascularized striated muscle that plays an important role in vocalization and swallowing. The surface of the tongue is lined with papillae which contain gustatory cells expressing various taste receptors. There is growing evidence to suggest our perceptions of taste and food preference are remodelled following chronic consumption of western diets rich in carbohydrate and fats. Our sensitivity to taste and also metabolism western diets may be a key factor in the rising prevalence of obesity but a systems-wide analysis is lacking. Here, we defined the proteomic landscape of the mouse tongue and quantified changes following chronic consumption of a chow or western diet for 7 months. We observed a dramatic remodelling of the tongue proteome including changes in fatty acid and mitochondrial metabolism. The expression of several receptors, and metabolic enzymes and hormones were also differentially regulated which is exciting as these may serve as novel therapeutic targets to potentially alter taste perception and food preference to combat obesity.

Project description:Background The vitamin A derivative, retinoic acid (RA), is a potent teratogenic agent that induces a variety of congenital abnormalities including neural tube defects. The embryopathology of RA has been extensively investigated and retinol receptors play important roles during organogenesis, development and neural tube closure. Still, the mechanisms by which RA influences these processes are not completely understood. Methods We used a custom-made mouse genome 32K oligonucleotide microarray to determine the gene expression profiles of mouse embryo spinal cord samples that had been exposed to vehicle or RA. Then, we performed a GSEA (gene set enrichment analysis) on the gene expression data by searching MSigDB (v2.5) c2 gene sets (canonical pathways) and c5 gene sets (curated GO terms), with set size restraints on the range to avoid over-narrow or over-broad categories. Results Using microarray technology, the present study identifies 85 genes in the spinal cord that exhibit at least a 1.5-fold change between control samples and samples with spina bifida aperta. A gene set enrichment analysis showed that maternal exposure to RA induced spinal bifida that were associated with altered expression of genes involved in pro- or anti-apoptosis, cell proliferation, migration, cytoskeleton components, and cell or focal adhesion, indicating that defective functions of these cell components and biological processes preceded the abnormal development of neural tube. Conclusions Maternal exposure to RA induced spinal bifida that were associated with altered expression of genes involved in pro- or anti-apoptosis, cell proliferation, migration, cytoskeleton components, and cell or focal adhesion. As shown in previous reports, defective functions of these cell components and biological processes preceded the abnormal development of the neural tube. Our study will help the understanding of the etiology and pathology of spinal bifida. However, it should be noted that the changes in gene expression induced by RA exposure may not be an effect on events other than neural tube closure; further study is required to fully understand the molecular mechanisms and consequence of neural tube defects in embryos exposed to RA. Our study provides a global analysis of gene expression patterns in spina bifida and will help the understanding of the etiology and pathology of neural tube defects. We assessed the changes in gene expression that coincide with spina bifida in RA-treated mouse fetuses. After generating an independent list of regulated genes, we analyzed samples by gene set enrichment analysis to expand our results. A pool of spinal cord tissue from spina bifida fetuses whose mothers were exposed to RA was compared to a pool of spinal cord tissue from fetuses whose mothers were exposed to olive oil vehicle. Three replicates each.
