Fucci-G1 insertion partially disrupts Shh expression

ABSTRACT: The Fucci mouse lines are valuable tools for tracing cell cycle stages during development and in postnatal tissues; however, the insertion loci for the transgenes remain unidentified. Here, we report the genomic insertion sites of both the Fucci-G1 and -S/G2/M transgenes, identified through whole genome sequencing. Interestingly, the Fucci-G1 transgene is located proximal to the Shh lung gut enhancer (SLGE) on chromosome 5. Homozygous Fucci-G1 embryos survive until embryonic day 18.5 (E18.5), exhibiting craniofacial and foregut-related defects, but are perinatal lethal. Expression of Shh and canonical targets are down-regulated in the pharyngeal arches of E11.5 homozygous Fucci-G1 embryos. Furthermore, in situ hybridization analysis showed diminished Shh expression in the pharyngeal ectoderm and foregut endoderm, consistent with disruptions to SLGE activity. Our results indicate that heterozygous Fucci-G1 mice are suitable for cell cycle studies; however, we caution potential genetic interference when investigating SHH-related pathways.

Cell cycle analysis of histone marks and 4C in human Fucci ESCs

Project description:Using the Fucci cell cycle indicator system in hESCs, we evaluated the patterns of bivalent histone marks and enhancer histone marks during the cell cycle by ChIP-seq. We further evaluated how the chromatin architecture changed during the cell cycle. We found that bivalent domains are cell cycle regulated, and H3K4me3 specifically peaks during the late G1 stage of the cell cycle. H3K27me3, however, is largely unchanged during the cell cycle. Cell cycle-regulated bivalent domains interact with enhancers and form cell cycle regulated chromatin interactions. FACS-isolated cell cycle fractions (DN, early G1; KO2, late G1; AzL, S-phase; and AzH, G2/M) from Fucci hESCs were subject to ChIP-seq for H3K4me3, H3K27me3, H3K27ac and H3K4me1, and used for sequencing along with input controls for each of the 4 cell cycle fractions (20 samples total), using Illumina platform, or 4C-seq for each cell cycle fraction using viewpoints neighboring the GATA6 or SOX17 promoters.

HCT 116 cells expressing Fucci (fluorescent ubiquitination-based cell cycle indicator); G1 phase vs. S/G2/M phase

Project description:Fucci-expressing HCT116 were inoculated into subcutaneous tissue or cecum of NOD/SCID mice. Four weeks after inoculation, Fucci green (mAG; S/G2/M) and red (mKO2;G1) expressing cells were isolated from implanted tumors by FACSAria sorting (BD, Biosciences). Comparative analyses among green and red cells cultured in vivo were performed to elucidate the molecular basis of cell cycle-dependent motility control mechanism.

Gene expression profiling by array of human non-transformed RPE-FUCCI (Fluorescent Ubiquitination-based Cell Cycle Indicator) cells

Project description:Progression through the cell cycle is driven by cyclin dependent kinases that control gene expression, orchestration of the mitotic spindle and cell division. Here we used a Fluorescent Ubiquitination-based Cell Cycle Indicator (FUCCI) and performed transcriptomic analysis of human non-transformed cells. Cell sorting allowed efficient isolation of G1, S and G2 cells from asynchronously growing cell cultures. Altogether, we identified 701 differentially expressed genes in G1 and G2 cells.

Expression data from Ezh2 epithelial knock-out mouse lungs at E14.5

Project description:Ezh2 epigenetically suppresses developmentally-regulated genes. Ezh2 is highly expressed during development, including in the lung. We knocked out Ezh2 in the developing lung epithelium using a Shh-cre driver which is active in foregut endoderm prior to lung morphogenesis. Many developmentally regulated genes became derepressed in the mutant lungs, leading to defects in lung development. Microarray analysis of genes upregulated in Ezh2 epithelial knock-out mouse lungs compared to Shh-cre controls. We generated Ezh2 epithelial mutant lungs by crossing the Ezh2-floxed line (Su et al., 2003) with the Shh-cre line (Harfe et al., 2004). We isolated RNA from whole mouse lungs at embryonic day 14.5 from 4 Shh-cre:Ezh2-flox/flox embryos (M1-M4) and 4 Shh-cre embryos (C1-C4). Littermates are as follows: C1+C2; C3+C4; M1+M2; M3+M4.

FUCCI Based Study of Toxoplasma Endodyogeny

Project description:In this study, we report the first application of the Fluorescent Ubiquitination-based Cell Cycle Indicator (FUCCI) in a unicellular eukaryote model. We created the ToxoFUCCIS and Toxo FUCCISC probes. Our analysis of ToxoFUCCIS and its derivatives co-expressing epitope- tagged cell cycle markers have revealed an unusual composite cell cycle phase that incorporates overlapping S, G2, mitosis and cytokinesis (budding).

Anterior and Posterior regions of mouse embryos with combinatory mutations of Fuz and Gpr161

Project description:Gpr161 and Fuz are Shh signaling molecules, and both null mutations are associated with neural tube defects in mice. As their genetic relationship in Shh signaling during neural tube development is unknown, we generated double homozygous null mutant mice for phenotyping and associated molecular changes. We observed the rescued NTD phenotypes in double homozygous null mutant embryos compared to those in single Gpr161 null mutant embryos. However, the range of rescued phenotypes is distinct between anterior and posterior NTDs. Therefore, we sought to identify the comparison in gene expression between the anterior and posterior regions of each genotype embryos and between each genotype.

Nkx2.5 regulates Jarid2 during outflow tract morphogenesis

Project description:The transcription factor Nkx2.5 is required for specification of pharyngeal arch second heart field (SHF) progenitors that contribute to outflow tract (OFT) and right ventricle (RV) formation. Multiple sets of microarray data were analyzed to identify genes that are candidate targets of Nkx2.5 in the second heart field. These sets are: 1) publicly available data for cardiothoracic tissue from E9.5 Nkx2.5 wild-type, heterozygous and homozygous embryos; 2) an analysis of mouse E10.5 pharyngeal arch tissue; 3) an analysis of mouse E12.5 heart tissue; and 4) a temporal analysis of the cardiogenic cell line P19CL6. This combined analysis identified 11 genes (Lrrn1, Elovl2, Safb, Slc39a6, Khdrbs1, Hoxb4, Fez1, Ccdc117, Jarid2, Nrcam, and Enpp3) expressed in SHF-containing pharyngeal arch tissue whose regulation is dependent on Nkx2.5 expression.
