Project description:We investigated the effect of Dgcr8-homozygous mutation on microRNA expression profile in mouse embryonic stem cells. MicroRNA expression was substantially impaired, indicating a pivotal role of DGCR8 in microRNA biogenesis. MicroRNA expression profile was compared between Dgcr8-homozygous mutant ES cells and wild-type ES cells

Project description:Two independent BayGenomics mouse embryonic stem cell lines (XH157 and XG058), each bearing a gene trap between exons 9 and 10 of the Dgcr8 locus (ENSMUST00000115633, Ensembl v53) were further mutagenised by the targetted insertion of a second Dgcr8 gene trap cassette. Consequently two independent heterozygous and two independent homozygous mutant Dgcr8 cells were derived (Dgcr8tm1,gt1/+, Dgcr8tm1,gt2/+, Dgcr8gt1/tm1 and Dgcr8gt2/tm1). Next generation sequencing was used to profile the small RNAs expressed in these cells together with wild type (E14) cells to determine the effect of these mutations on miRNA expression.

Project description:These experiments were conducted as part of a study to derive the targets of miRNAs. Two independent BayGenomics mouse embryonic stem cell lines (XH157 and XG058), each bearing a gene trap between exons 9 and 10 of the Dgcr8 locus (ENSMUST00000115633, Ensembl v53) were further mutagenised by the targetted insertion of a second Dgcr8 gene trap cassette. Consequently two independent heterozygous and two independent homozygous mutant Dgcr8 cells were derived (Dgcr8tm1,gt1/+, Dgcr8tm1,gt2/+, Dgcr8gt1/tm1 and Dgcr8gt2/tm1). A comparison of the expression profiles of the heterozygous cells to the Dgcr8 depleted cells allows the investigation of the broad role of miRNAs in mouse ES cells. Subsequently individual miRNA mimics were reintroduced into the Dgcr8-depleted background. The cells were allowed to recover for 10, 20 or 44 hours. The effect of the miRNA on the mRNA expression of the cells was assessed through the comparison of the expression profile of the transfected cells to that of cells transfected with a control mimic, which had recovered over the same period. This allows the roles of individual miRNAs to be investigated.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
