Expression data from cochlea isolated from N-myc mutant and wild-type mice at E15

ABSTRACT: The aim of this study consists in detecting genes regulated by N-myc in the murine cochlea In this data set we present 2688 genes differentially regulated by Nmyc in the murine cochlea. These data serve as a platform for verifying their differential regulation by N-myc via RNA in situ hybridisation or other techniques.

Expression data from cochlea isolated from N-myc mutant and wild-type mice at E15

Project description:The aim of this study consists in detecting genes regulated by N-myc in the murine cochlea In this data set we present 2688 genes differentially regulated by Nmyc in the murine cochlea. These data serve as a platform for verifying their differential regulation by N-myc via RNA in situ hybridisation or other techniques. 4 Total samples were analyzed. A pairwise comparison between two wild-type and 2 N-myc mutants samples was conducted. Genes with a FDR up to 14% are presented. Briefly, the robust microarray analysis (RMA) algorithm was used for background correction, intra- and inter-microarray normalization, and expression signal calculation. Once the absolute expression signal for each gene (i.e., the signal value for each probe set) was calculated in each microarray, a method [called significance analysis of microarray (SAM)] was applied to calculate significant differential expression and find the gene probe sets that characterized the highly metastatic samples. The method uses permutations to provide robust statistical inference of the most significant genes and provides P valuesadjusted to multiple testing using false discovery rate (FDR).

Analysis of the gene expression within the cochlea of aging C57BL6j mice.

Analysis of the gene expression within the cochlea of aging C57BL6j mice.

Project description:Gene expression within the cochlea of C57BL6j mice was examined. The hypothesis was that there was a genetic component to Age Related Hearing Loss and microarray would be useful in detecting candidate genes. Mice were aged in the laboratory to 4, 15 and 45 weeks of age. The cochlea were removed and pooled into groups of 5 for each age group. Total RNA was extracted and used in the micoroarray analysis. Differential expression was analysed between the different age groups i.e 4 - 15, 4 - 45 and 15 - 45 weeks.

Proteome Comparison of Different-Aged Cochlea

Project description:Our work describes the application of mass spectrometry-based label-free quantitative proteomics for the identification of differentially expressed proteins between different-aged cochlea. We report proteins exclusively present as well as up- and downregulated in the cochlear sensory epithelium at significant developmental stages. Additionally, we report proteins exclusively present on P3 that were recently identified in the cochlea for the first time. We use bioinformatics to provide insight on biological functions and potential primary and secondary partners of the differentially expressed proteins. This study provides the first differentially expressed proteome in the mammalian cochlea at significant developmental stages; before hearing, during the onset of hearing, and when hearing is fully developed. We believe that these results will provide insights into the function of proteins that change during development and identify potential protein biomarkers related to hearing impairments.

JMJD6 and NMYC binding examined by ChIP-seq in NMYC overexpressing CHP134 human neuroblastoma cells

Project description:JMJD6 (also known as PTDSR) is an important oncogene that is upregulated in 17q21-ter gained neuroblastoma.It plays a role in E2F and N-Myc-regulated gene pathways and neuroblastoma tumorigenesis Using ChIP-Seq, we profiled JMJD6 and NMYC binding in the NMYC overexpressing neuroblastoma cell line. We identified the genomic location of JMJD6 and NMYC binding peaks across the human genome.

Expression data of miRNA from mice cochlea during aging

Project description:To identify which miRNAs are involved in the onset and progression of age-related hearing loss in the mammalian cochlea We used miRNA microarrays to screen the miRNAs which exhibit the drastic changes in their expressing level during the aging of the cochlea The organ of Corti (OC), the major pathological sites of presbycusis in cochlea, was collected separately at 3 timepoints during the life span. Two strains were selected: C57bl/6j (as accelerated prebycusis model) and CBA/J (as naturally occured presbycusis model). The selected timepoints were: Postnatal 21 days (P21), 3 month (3m) and 9 month (9m) for C57 mice, and P21, 9m, 16m for CBA mice.

Gene expression dataset for whole cochlea of Macaca fascicularis

Project description:Macaca fascicularis (long-tailed, cynomolgus, or crab-eating macaque) is a highly advantageous model in which to study human cochlea with regard to both evolutionary proximity and physiological similarity of the auditory system. To better understand the properties of primate cochlear function, we analyzed the genes predominantly expressed in M. fascicularis cochlea.

scRNA-seq of P20 mouse cochlea

Project description:ARHL has been thought to result from disordered hair cell function and their loss. ARHL has a significant genetic component. We sought to determine the expression in the cochlea of genes associated with single nucleotide polymorphisms linked to ARHL. We find widespread and varying expression of genes associated with these SNPs in subtypes of cells in the cochlea identified by single-cell RNA sequencing. Genes associated with SNPs with the highest significance were preferentially expressed highly in hair cells while genes associated with SNPs with a lower significance were expressed more universally.

Expression data from proximal, middle, and distal segments of E6.5 chicken cochlea

Project description:Precise frequency discrimination is a hallmark of auditory function in birds and mammals. In the cochlea, tuning and spectral separation result from longitudinal differences in basilar membrane stiffness and numerous individual gradiations in sensory hair cell phenotypes, but it is unknown what patterns those phenotypes. Hypothesizing that morphogen levels might differ along the longitudinal axis of the developing cochlea, we sequenced the transcriptomes of the proximal, middle, and distal thirds of the chicken cochlea at E6.5, when postmitotic hair cells first form. Embryonic day 6.5 chicken cochlea were dissected. Three samples were collected from each cochlear duct by cutting the duct into three approximately equal sized pieces to produce proximal, middle, and distal pieces. Each sample contained a portion of the future tegmentum vasculosum and the basilar papilla sensory epithelium. The distal piece also contained the region fo the future lagena.
