*  Cell Mitosis - Animation Animation by Cynthia S. Gordon | Medical Illustration & Animation
This animation shows the process of cell mitosis. The various stages of cell division are shown, beginning with normal interphase, and passing through early and late prophase, metaphase, anaphase, and telophase, until the resultant two new daughter cells are formed. Two identical sets of chromosomes end up in each of these cells, along with equal amounts of cytoplasm and other organelles.

*  The cyclin B1 gene is actively transcribed during mitosis in HeLa cells | EMBO Reports
We investigated the occurrence of transcription during mitosis on an RNA pol II‐transcribed gene. We have found that the human cyclin B1 gene is actively transcribed at the mitotic stage. This result is surprising, since it is widely accepted that transcription is repressed during mitosis in higher eukaryotes. Interestingly, in fission yeast the rate of RNA synthesis is maintained during passage through mitosis (Baum et al., 1998). In mammalian cells, until now, no RNA pol II‐dependent transcription has been reported in mitotic cells, although there is evidence showing that 10-20% of the TFIID population remains associated with the condensed mitotic chromatin (Segil et al., 1996). Whether the transcription of the cyclin B1 gene occurs during all the four mitosis phases remains to be elucidated. The cyclin B1 protein is quickly degraded at the metaphase. Whenever a spindle checkpoint is imposed during metaphase, there is a reappearance of ...

*  A role for mitotic bookmarking of SOX2 in pluripotency and differentiation
Mitotic bookmarking transcription factors remain bound to chromosomes during mitosis and were proposed to regulate phenotypic maintenance of stem and progenitor cells at the mitosis-to-G1 (M-G1) transition. However, mitotic bookmarking remains largely unexplored in most stem cell types, and its functional relevance for cell fate decisions remains unclear. Here we screened for mitotic chromosome binding within the pluripotency network of embryonic stem (ES) cells and show that SOX2 and OCT4 remain bound to mitotic chromatin through their respective DNA-binding domains. Dynamic characterization using photobleaching-based methods and single-molecule imaging revealed quantitatively similar specific DNA interactions, but different nonspecific DNA interactions, of SOX2 and OCT4 with mitotic chromatin. Using ChIP-seq (chromatin immunoprecipitation [Chill combined with high-throughput sequencing) to assess the genome-wide distribution of SOX2 on mitotic chromatin, we demonstrate the ...

*  Cell Mitosis Overview Tutorial | Sophia Learning
After viewing the tutorial video and completing the Google Form, you should have an understanding of cell division by mitosis, including a knowledge of what occurs inside the cell during each of the phases of mitosis. A cell spends most of its life performing is normal functions. Most cells will spend a brief period of their life dividing. All cells come from other pre-existing cells. I call it the "secret to the continuation of life." Without mitosis, life would not continue. Through this process a mother cell divides into two genetically identical daughter cells. This process if relatively simple, however it must occur just as prescribed in order to create daughter cells that are clones of the mother cell. Key vocabulay in this less includes: chromosome, chromatid, centriole, and spindle fibers.

*  VCAC: Cellular Processes: Mitosis: The Movie -- Narrative
Mitosis-- Movie Narrative (Advanced Look). Cell division is required for an organism to grow, mature, and maintain tissues. During the mitotic phase, a cell will undergo mitosis to form two new nuclei and then divide to form two new individual cells during cytokinesis. Mitosis is the process of dividing the duplicated DNA of a cell into two new nuclei. Mitosis is split into distinct stages. The first stage is prophase; the DNA condenses, organizes, and the classic chromosome structure appears. Next comes prometaphase where microtubules attach to the chromosomes. This step is followed by metaphase where the chromosomes align. Metaphase is followed by anaphase where the chromosomes separate. Finally, during telophase nuclear membranes reappear around the two sets of chromosomes. Mitosis is now complete. After mitosis two new cells are formed by a process called cytokinesis.. Mitosis is only ...

*  Sec16A restarts secretion post mitosis | Journal of Cell Science
Precise inheritance of organelles during mitosis ensures the proper organisation and function of daughter cells. Inheritance of the Golgi complex, a single copy organelle, requires its disassembly before mitosis; Golgi disassembly is driven by mitotic inhibition of COPII-dependent export of proteins from endoplasmic reticulum exit sites (ERESs) to the Golgi. Helen Hughes and David Stephens have been investigating how ERESs are restored at the end of mitosis and, on page 4032, they report that Sec16A - the major human orthologue of Sec16, which defines the site of COPII vesicle budding in yeast - defines the site at which COPII-dependent budding reinitiates after mitosis. Using quantitative 4D imaging of HeLa cells stably expressing fluorescently labelled Sec16A, the authors show that, unlike all other COPII components, Sec16A remains associated with ERESs throughout mitosis. Moreover, Sec16A localisation is coincident with ...

*  Plus it
The constitutive heterochromatin of the centromere is marked by high levels of tri-methylated histone H3 Lysine 9 (H3K9) and binding of the heterochromatin protein 1 (HP1), which are thought to also have an important role in mitosis. Histone deacetylase inhibitors (HDACi) are a class of anticancer agents which affect many cellular processes, including mitosis. Here we examine the mechanism by which these drugs disrupt mitosis. We have used Drosophila embryos to demonstrate that treatment with the HDACi 100 μg/ml suberic bishydroxamic acid (SBHA, IC50 12 μg/ml), conditions that induce extensive H3K9 acetylation and aberrant mitosis in mammalian cells, induced aberrant mitosis in the absence of de novo transcription. We have examined the effect of the same treatment on the levels of H3K9 modification and HP1 binding in human cancer cells, and found only minor effects on H3K9 methylation and HP1 binding.

*  Nuclear shape, growth and integrity in the closed mitosis of fission yeast depend on the Ran-GTPase system, the spindle pole...
During interphase in all eukaryotic cells the double lipid bilayer of the nuclear envelope (NE) physically separates the chromosomes, and chromosome-related processes, from the cytoplasm and increases in area by 59% (Lim et al., 2007) as the nuclear volume doubles in preparation for mitosis (reviewed by Hetzer et al., 2005; Lim et al., 2007; Winey et al., 1997). In the open mitosis of animal cells, NE breakdown allows the spindle microtubules that are nucleated by the cytoplasmic centrosomes to attach to and then separate the chromosomes. In the closed mitosis of yeast, the centrosome equivalents, called spindle pole bodies (SPBs), are embedded in the NE and nucleate the formation of an intranuclear spindle (Ding et al., 1997). As the spindle elongates in anaphase B, nuclear volume remains constant but division of the roughly spherical nucleus into two smaller spheres, which occurs in less than 5 minutes, requires a rapid increase of 26% in NE area (Lim et ...

*  article ; Mitosis in Cell (2)
mītōˈsĭs, mĭ-, process of nuclear division in a living cell by which the carriers of hereditary information, or the chromosomes, are exactly replicated and the two copies distributed to identical daughter nuclei. Mitosis is almost always accompanied by cell division (cytokinesis), and the latter is sometimes considered a part of the mitotic process. The pattern of mitosis is fundamentally the same in all cells. However, while animal cells apparently divide by pinching into two separate cells, plant cells develop a cell plate, which becomes a cellulose cell wall between the two daughter cells. The importance of mitosis is the maintenance of the chromosomal set; each cell formed receives chromosomes that are alike in composition and equal in number to the chromosomes of the parent cell.. The Stages of Mitosis Mitosis is simply described as having four stages-prophase, metaphase, anaphase, and telophase; the steps follow one ...

*  Mitotic checkpoint serine/threonine-protein kinase BUB1 beta
Essential component of the mitotic checkpoint. Required for normal mitosis progression. The mitotic checkpoint delays anaphase until all chromosomes are properly attached to the mitotic spindle. One of its checkpoint functions is to inhibit the activity of the anaphase-promoting complex/cyclosome (APC/C) by blocking the binding of CDC20 to APC/C, independently of its kinase activity. The other is to monitor kinetochore activities that depend on the kinetochore motor CENPE. Required for kinetochore localization of CENPE. Negatively regulates PLK1 activity in interphase cells and suppresses centrosome amplification. Also implicated in triggering apoptosis in polyploid cells that exit aberrantly from mitotic arrest. May play a role for tumor suppression ...

1. What is mitotic cell division used for in single-celled organisms? In multicellular organisms?. In single-celled organisms, mitotic cell division creates more genetically identical individuals (a clone of individuals). In multicellular organisms, mitotic cell division is used for growth, development, and tissue renewal as well as sometimes for asexual reproduction.. 2. How is DNA packaged in eukaryotic organisms?. In eukaryotic chromosomes, DNA is packaged around a main protein scaffold and wound around histone proteins.. 3. What is a chromosome? A chromatid? Chromatin?. A chromosome is a single strand of DNA organized around the packaging proteins. It has a single centromere. A chromatid is one of a pair of replicated DNA molecules still connected by a common centromere. Chromatin is the DNA + protein that makes up the chromosome. It was so named early in microscopy because it stained darkly ("chromatin" = "colored stuff"). 4. If there are 20 centromeres in a cell, how many chromosomes are ...

*  BubR1 acetylation at prometaphase is required for modulating APC/C activity and timing of mitosis | The EMBO Journal
When the APC complex was inhibited by siRNA of APC3, the level of BubR1 remained constant for 60 min after nocodazole release in the presence of CHX, whereas it declined in control cells (Figure 8B). This result was corroborated by the finding from live‐cell assay for proteolysis that depleting APC3 expression abrogated the degradation of BubR1, and concomitantly cells did not enter anaphase for more than 5 h (Supplementary Figure 12 and Supplementary movie 7). When we compared the timing of BubR1 degradation with the degradation of other players in mitosis, such as Cdc20, Cyclin B, Plk1, and Aurora A, we found that BubR1 degradation began before that of Cyclin B (Supplementary Figure 13).. Next, we tested whether Cdc20 was responsible for BubR1 degradation during mitosis. To prevent the cells from exiting mitosis before the analysis began, HeLa cells were transfected with an expression construct to force moderate expression of Cyclin B. siRNA for GFP, ...

Protein phosphatase which antagonizes mitotic cyclin-dependent kinase CDC28, the inactivation of which is essential for exit from mitosis. To access its substrates, is released from nucleolar sequestration during mitosis. Plays an essential in coordinating the nuclear division cycle with cytokinesis through the cytokinesis checkpoint. Involved in chromosome segregation, where it is required for meiosis I spindle dissambly as well as for establishing two consecutive chromosome segregation phases. Allows damaged actomyosin rings to be maintained to facilitate completion of cell division in response to minor perturbation of the cell division machinery. Inhibits transcription of ribosomal genes (rDNA) during anaphase and controls segregation of nucleolus by facilitating condensin targeting to rDNA chromatin in anaphase. Dephosphorylates SIC1, a CDC28 inhibitor, and SWI5, a transcription factor for SIC1, and induces degradation of mitotic cyclins, likely by dephosphorylating the ...

*  ELM - Detail for LIG APCC ABBAyCdc20 2
Cdc20 joins the APC/C in early mitosis and is then replaced by Cdh1 during anaphase. APC/C regulates mitosis by degrading cyclins, the regulatory subunits of cyclin-dependent kinases (CDKs), which control the cell cycle by phosphorylation of specific cell cycle related proteins. In addition, the APC/C controls the degradation of securin and other proteins, thereby triggering chromosome segregation in anaphase (Di Fiore,2015). During the mitotic phase of the cell cycle, chromosomes are separated into two identical sets. After duplication in S phase, a large protein complex assembles at each centromere, called the kinetochore. Kinetochores serve as docking site for attachment of chromatids to spindle microtubules during anaphase, thereby generating tension across sister chromatids. To prevent deficient chromatid separation, the spindle assembly checkpoint (SAC) is responsible for surveillance of the cell cycle. In early mitosis, activation of SAC leads to the ...
