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. The labeled cRNAs were hybridized on 4X44K Agilent Whole Human Genome dual colour Microarrays (G4112F) in two dye swap experiments, resulting in four individual microarrays.

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.

Project description:Regulation of cell cycle progression is essential for cell proliferation during regeneration following injury. After appendage amputation, the axolotl (Ambystoma mexicanum) regenerates missing structures through an accumulation of proliferating cells known as the blastema. To study cell division during blastema growth, we generated a transgenic line of axolotls that ubiquitously expresses a bicistronic version of the fluorescent ubiquitination-based cell-cycle indicator (FUCCI). We demonstrate near-ubiquitous FUCCI expression in developing and adult tissues, and validate these expression patterns with DNA synthesis and mitosis phase markers. We demonstrate the utility of FUCCI for live and whole-mount imaging, showing the predominantly local contribution of cells during limb and tail regeneration. We also show that spinal cord amputation results in increased proliferation at least 5 mm from the site of injury. Finally, we use multimodal staining to provide cell type information for cycling cells by combining fluorescence in situ hybridization, EdU click-chemistry and immunohistochemistry on a single FUCCI tissue section. This new line of animals will be useful for studying cell cycle dynamics using in situ endpoint assays and in vivo imaging in developing and regenerating animals.

Project description:RATIONALE:Understanding and manipulating the cardiomyocyte cell cycle has been the focus of decades of research, however the ultimate goal of activating mitotic activity in adult mammalian cardiomyocytes remains elusive and controversial. The relentless pursuit of controlling cardiomyocyte mitosis has been complicated and obfuscated by a multitude of indices used as evidence of cardiomyocyte cell cycle activity that lack clear identification of cardiomyocyte "proliferation" versus cell cycle progression, endoreplication, endomitosis, and even DNA damage. Unambiguous appreciation of the complexity of cardiomyocyte replication that avoids oversimplification and misinterpretation is desperately needed. OBJECTIVE:Track cardiomyocyte cell cycle activity and authenticate fidelity of proliferation markers as indicators of de novo cardiomyogenesis in post-mitotic cardiomyocytes. METHODS AND RESULTS:Cardiomyocytes expressing the FUCCI construct driven by the α-myosin heavy chain promoter were readily and uniformly detected through the myocardium of transgenic mice. Cardiomyocyte cell cycle activity peaks at postnatal day 2 and rapidly declines thereafter with almost all cardiomyocytes arrested at the G1/S cell cycle transition. Myocardial infarction injury in adult hearts prompts transient small increases in myocytes progressing through cell cycle without concurrent mitotic activity, indicating lack of cardiomyogenesis. In comparison, cardiomyogenic activity during early postnatal development correlated with coincidence of FUCCI and cKit+ cells that were undetectable in the adult myocardium. CONCLUSIONS:Cardiomyocyte-specific expression of Fluorescence Ubiquitination-based Cell Cycle Indicators (FUCCI) reveals previously unappreciated aspects of cardiomyocyte cell cycle arrest and biological activity in postnatal development and in response to pathologic damage. Compared to many other methods and model systems, the FUCCI transgenic (FUCCI-Tg) mouse represents a valuable tool to unambiguously track cell cycle and proliferation of the entire cardiomyocyte population in the adult murine heart. FUCCI-Tg provides a desperately needed novel approach in the armamentarium of tools to validate cardiomyocyte proliferative activity that will reveal cell cycle progression, discriminate between cycle progression, DNA replication, and proliferation, and provide important insight for enhancing cardiomyocyte proliferation in the context of adult myocardial tissue.

Project description:This experiment examines how toxicants can override normal stemness (NS) conditions, which LIF maintains, causing lineage imbalance and otherwise affecting cells in the early embryo. It also compares NS to normal differentiation (ND) (without LIF/ LIF-). Sorbitol is a positive control for stress overriding LIF+. Retinoic acid (RA) modified LIF- is a positive control for 1st lineage differentiation. But RA also activates Hox gene in anterior posterior patterning at gastrulation. The third control is NS itself, and all stimuli are compared to NS. Other toxicants are Benzo(a)pyrene (BP) - a mutagen, Cortisol - a stress hormone, and two endocrine disruptors Diethyl phthalate (DEP), and Perfluorooctanoic acid (PFOA).

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.
