Project description:CREB regulates lens EMT in both S133 phosphorylation dependent and independent manners. We found that S133A-CREB activated, while R314A-CREB attenuated lens mesenchymal marker gene Fn1 and Snail2. To better understand the mechanism by which S133A and R314A mutations modulate EMT gene expression. RNA-seq on the alpha-TN4 overexpressing Vector, WT-CREB, KCREB, R314A-CREB, S133A-CREB, S133A-KCREB and S133A/R314A -CREB before and after TGFβ treatment.

Analyzing CREB binding motif and sites in the mouse lens epithelial cells alpha-TN4 overexpressing Vector, WT-CREB, S133A-CREB, R314A-CREB and S133A/R314A –CREB.

Project description:Transcription factor CREB regulates lens Epithelial-Mesenchymal Transition（EMT）in both S133 phosphorylation dependent and independent manners. We found that S133A-CREB can activate lens EMT, while R314A-CREB attenuated it. To understand the mechanism by which S133A-CREB and R314A-CREB modulates EMT gene expression. ChIP assay using CREB antibody in the in the mouse lens epithelial cells alpha-TN4 overexpressing Vector, WT-CREB, S133A-CREB, R314A-CREB and S133A/R314A-CREB, and ChIP-seq was conducted on the ChIP DNA. We found that WT-CREB, S133A-CREB as well as R314A-CREB binds to the promoter regions of mesenchymal genes, and S133A-CREB retained canonical CREB binding motif, while R314A-CREB exhibited shifted binding motif preference to ATF1.

Comprehensive gene expression pattern of developing lens of Foxp1 lens specific knockout mice

Project description:Foxp1 was strongly expressed in developing lens, and its knockout in lens resulted in failure of appropriate lens development. By microarray analysis, we examined effects of loss-of Foxp1 for gene expression pattern of lens at P0 developmental stage.

Nuclear Organization of Lens Epithelium and Fiber Cells in Newborn Lens

Project description:Cellular differentiation is marked by temporally and spatially coordinated gene expression regulated at multiple levels within the nucleus. Sequence-specific DNA-binding transcription factor CTCF EDIT. Topologically associated domains (TADs). Using Hi-C, we investigated changes in chromatin organization between newborn (P0.5) mouse lens fiber and epithelium and compared them to embryonic stem (ES) cells. Compartments A and B. Using ChIP-seq, we determined localization of CTCF in both lens tissues Formation of lens-specific TADs is demonstrated via comparative studies of chromatin at Pax6, Prox1, Gata3, Hsf4, and crystallin loci (to be updated) between lens and ES cell nuclei. Our study has generated the first data on nuclear organization in lens epithelium and lens fibers and directly compared these data with ES cells.

Chromatin remodeling enzyme Brg1 is required for mouse lens fiber cell terminal differentiation and their denucleation [lens tissue]

Project description:Genome-wide approach to identify the cell-autonomous role of Brg1 in lens fiber cell terminal differentiation. To examine roles of Brg1 in mouse lens development, a dnBrg1 transgenic construct was expressed using the lens-specific alphaA-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 IIbeta, 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. Wild type and dnBrg1 transgenic lenses, 4 biological replicates each
