Project description:RNA-seq of organ of Corti RNA from mice carrying a null allele of Mir183 and Mir96
| PRJEB21214 | ENA
Project description:The microRNA miR-96 is important for hearing; mutations in the seed region result in dominant progressive hearing loss in mice and humans. Mir96 is expressed in the sensory hair cells of the organ of Corti along with Mir182 and Mir183. miR-96 is a master regulator of hair cell development, controlling many genes in the organ of Corti, but the role of miR-182 and miR-183 in the hair cells is unknown. We carried out RNA-seq on mice carrying a knockout allele of Mir182, and mice carrying a double knockout allele of Mir183 and Mir96 (Mir183/96). RNA was extracted from the organ of Corti from P4 homozygotes and sex-matched wildtype littermates. Strand-specific libraries were prepared using the NuGEN Ovation Mouse RNA-Seq System 1-16 kit and sequenced on an Illumina HiSeq 2500 machine as paired-end 125bp reads.

Project description:C57B6J mice carrying a LacZ allele at the Math1 locus (Math1-LacZ/+) were backcrossed at least 10 generations. The LacZ allele phenocopies a null allele. A total of 5 heterozygous and 5 homozygous null spinal cords were collected (staged at embryonic day 12.5) and individually processed (i.e. not pooled). RNA was extracted and prepared for hybridization to Affymetrix MOE430v2.0 chips under standard conditions (www.affymetrix.com)

Project description:The purpose of this study was to examine the role of ZBP1 in the phenotype that develops when ADAR1 activity is missing, in particular when the Zα domain of ADAR1 is mutated. Mice homozygous for a Zα domain-mutant allele of Adar1 (Adar1mZα/mZα mice) were compared with control mice carrying one mZα allele and one wild type allele of Adar1 (Adar1wt/mZα mice) and with mice carrying one mZα and one null Adar1 allele (Adar1-/mZα mice). Adar1-/mZα mice were also compared with mice additionally deficient in ZBP1 (Adar1-/mZα Zbp1-/- mice). Given the early postnatal lethal phenotype that develops in Adar1-/mZα mice, comparisons were made in RNA isolated from spleen tissue from newborn mice of each genotype (5 mice per genotype).

Project description:The purpose of this study was to examine the role of MAVS and ZBP1 in the phenotype that develops when ADAR1 activity is missing, in particular when the Za domain of ADAR1 is mutated. Mice homozygous for a Za domain-mutant allele of Adar1 (Adar1mZa/mZa mice) were compared with control mice carrying one mZa allele and one wild type allele of Adar1 (Adar1wt/mZa mice) and with mice carrying one mZa and one null Adar1 allele (Adar1-/mZa mice). Adar1-/mZa mice were also compared with mice additionally deficient in ZBP1 (Adar1-/mZa Zbp1-/- mice) or MAVS (Adar1-/mZa Mavs-/- mice). Given the early postnatal lethal phenotype that develops in Adar1-/mZa mice, comparisons were made in RNA isolated from brain tissue from newborn mice of each genotype (4 mice per genotype).

Project description:Wild type and Dicer null embryonic mouse limbs were analaysed using Affymetrix arrays to identify gene expression changes. Genes that were up-regulated in Dicer-null limbs were canidates for being miRNA targets. Potential miRNA target genes were validated using qRTPCR. Mice carrying a heterozygous Dicer floxed allele and the prxcre driver allele were crossed to homozygous Dicer Floxed mice. Embryos were harvested from pregent moms and genotyped to determine heterozygous, Wild type and mutant limb buds. These limb buds were used to prepare RNA for array analysis.

Project description:Two highly conserved transcription factors STAT5A and STAT5B play an identical role in the intracellular signaling pathway upon cytokine stimulation, while gene deletion experiments have revealed separable and overlapping functions of STAT5. This questions whether the phenotypic differences in the organ development observed in the individual knockout mice result from isoform-specific functions or quantitative differences in the expression levels of each STAT5 isoform among tissues. To elucidate the redundancy and isoform-specificity of STAT5 for development at molecular levels, mice carrying only a single allele of either Stat5a or Stat5b were generated. Both of these mice overcame the lethal anemia observed in Stat5ab-null mice, indicating that development of erythroid cell lineage was totally dependent on the dosage of STAT5. The blocked progression of B cell lineage at the pre-pro B cell stage in Stat5ab-/- mice was rescued in the presence of a single allele of either Stat5a or Stat5b, while the number of total B220+ cells in bone marrow was smaller in Stat5abnull/Stat5b- mice than Stat5abnull/Stat5a- mice. The paucity of alveolar progenitor cells in the Stat5ab-null mammary epithelium was rescued by a single allele of either Stat5a but not Stat5b, suggesting cell-type dependent isoform-specific function. Genome-wide gene expression analyses revealed that different steps of cell lineage progression require different gene sets which expression requires the different isoform of STAT5 in a dose-dependent manner in the mammary epithelium. Taken together, this study demonstrates that dose-dependent isoform specificity of STAT5A and STAT5B controls progression and differentiation of each cell lineage. Six days after observation of a plug, mammary tissues from three of each Stat5a-/- mice, Stat5ab+/null mice, Stat5abnull/Stat5b- and Stat5abnull/Stat5a- mice were collected, frozen in liquid nitrogen, and stored at -70 °C

Project description:The purpose of this study was to examine the role of MAVS, ZBP1 and RIPK3 in the phenotype that develops when ADAR1 activity is impaired, in particular when the Za domain of ADAR1 is mutated. Mice homozygous for a Za domain-mutant allele of Adar1 (Adar1mZa/mZa mice) and mice carrying one mZa and one null Adar1 allele (Adar1-/mZa mice) were compared with control mice that were either wild type or heterozygous for the Adar1 mZa allele (Adar1wt/mZa mice). The effects of MAVS deficiency, RIPK3 deficiency, ZBP1 deficiency or ZBP1 Za domain mutations were assessed by analysing compound mutant mice. Given the early postnatal lethal phenotype that develops in Adar1-/mZa mice, comparisons were made in RNA isolated from lung tissue from newborn mice of each genotype (5 mice per genotype). As Adar1-/mZa mice additionally lacking Mavs or Zbp1 are viable, adult mice (15-20 weeks of age) were also used for several compound mutations as donors of lung tissue.
