Project description:There is not information regards the role of miRNAs in the development of the external ear in mammals. The aim of this study was to determine the stage-specific expression of miRNAs during external ear development in order to identify miRNAs and their possible targets. GeneChip miRNA 3.0 arrays by Affymetrix were used to obtain miRNA expression profiles from mice fetal pinnae and skin back tissues at 13.5 dpc and 14.5 dpc, biological triplicates for each tissue were analyzed; one litter represents one biological replica, each litter with 16 fetuses in average.

Project description:The inner ear in mammals is derived from a simple ectodermal thickening called the otic placode. Through a series of complex morphological changes, the placode forms the mature inner ear comprising of the auditory organ (cochlea) and the vestibular/balance organs (utricle, saccule, and three semi-circular canals). The vast majority of genes known to be involved during inner ear development have been found through mutational screens or by chance. To identify genes that can serve as novel candidates required for inner ear development, and also candidate genes for uncloned human deafnesses, inner ear tissues from mouse embryos from E9 to E15 were microdissected and expression-profiled at half-day intervals. Also profiled was the non-inner ear mesenchymal tissue surrounding the inner ear tissue. Various patterns of gene expression were identified, and significant biological pathways that these genes represented were identified. Also identified were mouse genes whose human orthologs are located within uncloned non-syndromic deafness intervals, thus serving as candidates for sequence analysis.

Experiment Overall Design: Inner ear tissues from E9 to E15 were microdissected at half-day intervals. E9 is the earliest stage when the otic placode is clearly visible and able to be microdissected cleanly. E15 is the stage when all the organs of the inner ear have become established, as have the sensory hair and non-sensory support cells within those organs. For each of the stages from E9 to E10, whole inner ears were profiled. For each of the stages from E10.5 to E12, the primordial cochlear and vestibular organs were profiled separately. For each of the stages from E12.5 to E15, the cochlea and the saccule were profiled separately, whereas the utricle and the three ampullae were combined and profiled together. Any given tissue from any given stage was a collection of anywhere between 4 to 17 identical tissues, and was obtained in duplicate (i.e. from different litters). Hence, a total of 58 inner ear samples were obtained. Moreover, non-inner ear tissue found in the immediate vicinity of inner ear tissue was also obtained and profiled. Specifically, all non-inner ear tissue from E9 was profiled in duplicate. Non-inner ear tissue from E9.5 to E10.5 was pooled and profiled together (in duplicate), whereas that from E11 to E15 was pooled and profiled together (also in duplicate). Therefore, a total of 6 non-inner samples were obtained.

Project description:There is no information regarding the role of microRNAs in the development of the external ear in mammals. The purpose of this study was to determine the stage-specific expression of microRNA during external ear development in mice under normal conditions. GeneChip miRNA 3.0 arrays by Affymetrix were used to obtain miRNA expression profiles from mice fetal pinnae and back skin tissues at 13.5 days-post-coitum (dpc) and 14.5 dpc. Biological triplicates for each tissue were analyzed; one litter represents one biological replica, each litter had 16 fetuses on average. The results were analyzed with Affymetrix's Transcriptome Analysis Console software to identify differentially expressed miRNAs. The inquiry showed significant differential expression of 25 miRNAs at 13.5 dpc and 31 at 14.5 dpc, some of these miRNAs were predicted to target genes implicated in external ear development. One example is mmu-miR-10a whose low expression in pinnae is known to impact ear development by modulating Hoxa1 mRNA levels Garzon et al. (2006), Gavalas et al. (1998) [1], [2]. Other findings like the upregulation of mmu-miR-200c and mmu-miR-205 in the pinnae tissues of healthy mice are in agreement with what has been reported in human patients with microtia, in which down regulation of both miRNAs has been found Li et al. (2013) [3]. This study uncovered a spatiotemporal pattern of miRNA expression in the external ear, which results from continuous transcriptional changes during normal development of body structures. All microarray data are available at the Gene Expression Omnibus (GEO) at NCBI under accession number GSE64945.

Project description:SOX10 (SRY-box 10) mutation may lead to inner ear deformities. However, its molecular mechanisms on inner ear development are not clear. In this work. The inner ear morphology was investigated at different embryonic stages of the SOX10 mutation miniature porcine model with sensorineural hearing loss, and high-throughput RNA-seq and bioinformatics analyses were applied. Our results indicated that the SOX10 mutation in the miniature pigs led to an incomplete partition of the cochlea, a cystic apex caused by fusion from middle and apical turns, cochlear modiolar defects and a shortened cochlear duct. The model demonstrated 173 DEGs and 185 lncRNAs. The down-regulated DEGs most significantly enriched the inflammatory mediator regulation of the TRP channels, arachidonic acid metabolism, and the salivary secretion pathways, while the up-regulated DEGs most significantly enriched the systemic lupus erythematosus and alcoholism pathways. Based on gene cluster analysis, we selected four gene groups: WNT1, KCNQ4, STRC and PAX6.

Project description:The genes involved in inner ear development have yet to be fully characterized. Previous gene-based analyses have primarily focused on the early developmental stages following induction and initial formation of the inner ear. The inner ear continues to grow and develop until the auditory and vestibular systems reach full maturity; all of the genes involved in this process have yet to be identified. The aim of this study is to identify additional candidate genes for inner ear development. Microarrays were used to produce expression profiles from the post-metamorphic juvenile stage of the Xenopus laevis inner ear.

Project description:Macrophages play an essential role in tissue regeneration. However, the ability to dissect the role of macrophages in regeneration from their role in wound healing with scar has been hampered by a lack of comparative systems. In this study, we use a mammalian model of tissue regeneration and scar formation to contrast the role of macrophages in both wound healing paradigms. The African Spiny mouse (A. cahirinus) can regenerate tissue of the external ear pinnae after 4mm biopsy punch. The common lab mouse (M. musculus) forms a scar after the same injury. We test the potential of bone marrow derived macrophages from both species to activate local ear fibroblasts and find macrophages from A. cahirinus are able to induce a matrix turnover phenotype in fibroblasts from both species. We identify growth factors and cytokines specific to macrophages derived from A. cahirinus, and using single cell RNAseq and screening with these factors, we identify populations of macrophages unique to a regenerating injury compared to scar forming injury. Finally we test how macrophage populations change over time in a regenerating injury and how they differ from each stage in a scar forming system

Previous gene based analysis have primarily focused on the early developmental stages following induction and initial formation of the inner ear. The aim of this study is to identify new candidate genes for inner ear development. Microarrays were used to produce expression profiles from larval stages 56,57,58 of the Xenopus laevis inner ear. The data produced from this work represent an annotated resource that can be utilized by the Xenopus community to provide candidates for further functional analysis. Xenopus inner ears were isolated from larval animals for RNA extraction and hybridization to Affymetrix GeneChip microarrays.
