Project description:Celf1 germline or conditional deletion mouse mutants exhibit fully penetrant lens defects including cataract. To gain insight into gene expression changes underlying these lens defects, microarray comparison was performed for lenses obtained from wild-type and Celf1 conditional deletion mutant mice. At ±2.0 fold-change cut-off (p<0.05), 102 genes were identified to be differentially expressed in Celf1 conditional mutant lenses

Project description:During development the fetal heart undergoes a rapid and dramatic transition to adult function through transcriptional and post-transcriptional mechanisms, including alternative splicing (AS). We performed deep RNA-sequencing for high-resolution analysis of transcriptome changes during postnatal mouse heart development using RNA from ventricles and freshly isolated cardiomyocytes (CM) and cardiac fibroblasts (CF). Extensive changes in gene expression and AS occur primarily between postnatal days 1 and 28. CM and CF showed reciprocal regulation of gene expression during postnatal development reflecting differences in proliferative capacity, cell adhesion functions, and mitochondrial metabolism. We found that AS plays a novel role in vesicular trafficking and membrane organization during postnatal CM development. Interestingly, these AS transitions are enriched among targets of two RNA-binding proteins, Celf1 and Mbnl1, which undergo developmentally regulated change in expression. Vesicular traffic genes affected by AS during normal development where Celf1 is down-regulated, showed a reversion to neonatal AS patterns when Celf1 was over-expressed in adults. RNA-seq was performed in RNA samples of ventricles, cardiomyocytes or cardiac fibroblast at different developmental stages; embryonic day 17, postnatal day (PN) 1, 10, 28 and 90 for ventricles, PN1-3, PN28 and PN60 for cardiac fibroblasts, and PN1-2, PN30, and PN67 for cardiomyocytes

Project description:Purpose: While the bioinformatics gene-discovery tool iSyTE (integrated Systems Tool for Eye gene discovery) has proved effective in identifying new cataract-linked genes, it primarily depended on lens-enriched expression of just three wild-type mouse embryonic stages. To increase iSyTE’s efficacy, a broad range of embryonic (E) and postnatal (P) lens microarray datasets from wild-type and specific gene-perturbation mutant mice were analyzed and a new web-interface was developed for their effective access and downstream-analysis. Methods: Five new mouse lens microarrays were generated and analyzed with all publicly available Affymetrix and Illumina lens datasets representing the stages E9.5, E10.25, E10.5, E11.5, E12.5, E15.5, E16.5, E17.5, E19.5, P0, P2, P4, P8, P12, P20, P28, P30, P42, P52, P56, P60 and mouse mutants for the genes: Brg1, CBP:p300, E2f1:E2f2:E2f3, Foxe3, Hsf4, Klf4, Mafg:Mafk, Notch2, Pax6, Sparc, Tdrd7. Results: The integrated lens microarray analysis accurately reflects established gene expression patterns and defines a new lens-signature gene-set for embryonic and postnatal stages that includes several novel candidates namely, Grifin, Ogn, Fabp5, Mboat1, Tmem40, Dhx32, Aldoc, Pgam2, Hmgn3, Mocs2, Gprc5b, Gstm1, Npl, and Zbtb8b. Combined analyses of 32 developmental/genetic data-conditions identifies several new transcription and signaling factors that potentially function in lens development and/or homeostasis. Conclusions: The updated iSyTE web-interface: (1) comprehensively informs on normal lens developmental and cataract-associated transcriptome dynamics and identifies new high-priority candidates for these processes, and (2) offers user-friendly visualization.

Project description:Microarray Analyses of Newborn Mouse lens lacking HSF4. Hsf4 is essential for lens development.

Project description:Differential expression of HSF4 in null newborn mouse and wildtype lenses was examined to identify putative downstream targets of HSF4. To examine roles of Brg1 in mouse lens development, a dnBrg1 transgenic construct was expressed using the lens-specific aA-crystallin promoter in postmitotic lens fiber cells. Morphological studies revealed abnormal lens fiber cell differentiation in transgenic lenses resulting in cataract. Electron microscopic studies showed abnormal lens suture formation and incomplete karyolysis (denucleation) of lens fiber cells. To identify genes regulated by Brg1, RNA expression profiling was performed in E15.5 embryonic wild type and dnBrg1 transgenic lenses. In addition, comparisons between differentially expressed genes in dnBrg1 transgenic, Pax6 heterozygous, and Hsf4 homozygous lenses identified multiple genes co-regulated by Brg1, Hsf4 and Pax6. Among them DNase IIb, a key enzyme required for lens fiber cell denucleation, was found downregulated in each of the Pax6, Brg1 and Hsf4 model systems. Lens-specific deletion of Brg1 using conditional gene targeting demonstrated that Brg1 was required for lens fiber cell differentiation and indirectly for retinal development but was not essential for lens lineage formation.
