During mitosis in Trypanosoma cruzi ten dense plaques originate from the single, large nucleolus present in interphase and the preliminary phase of mitosis. Each plaque becomes associated with two microtubular bundles which end at the poles of the dividing nucleus. After an equilibrium phase in ...
During mitosis in animal cells, at which phase do centrioles begin to move apart? How do plant cells divide without centrioles? How do prokaryotes function without organelles? What happens when a cell is specialized? How is mitosis the same for animal and plant cells? What happens in lysoso...
It has been recently discovered that nonmuscle caldesmon, an actin and calmodulin binding microfilament-associated protein of relative molecular mass Mr = 83,000, is dissociated from microfilaments during mitosis, apparently as a consequence of mitosis-specific phosphorylation. cdc2 kinase, which is a...
4b). Several of these interactors were reported to be phosphorylated during S phase, mitosis35 (71/479) and in response to DNA damage when ATR is hyperactive4 (48/479) (Supplementary Fig. 4c). We found several ATR interactors for which previous studies have identified roles in the ...
Heatmaps of single cells indicating replication status based on binarized copy number during preimplantation embryogenesis (red, replicated; grey, not replicated). Cells are ranked by their percentage of replicated genome (replication score), which indicates progress in S phase and is plotted as a ...
Meiosis I is quite similar to mitosis.However,there are a number of crucial differences between meiosis I and mitosis,all of which will be outlined in the discussion of each individual stage below.Interphase IJust as in mitosis,the cell undergoes DNA replication during this intermediate phase....
Erk activity is rapidly extinguished just prior to mitosis, which we refer to as mitotic erasure, inducing periods of inactivity, thus providing a source of heterogeneity in an asynchronously dividing tissue. Our modified reporter and transgenic lines represent an important resource for interrogating ...
In addition, during the initial stage of liver regeneration, HSCs can also produce norepinephrine (NP), which is known to downregulate the inhibitory effect of transforming growth factor-beta (TGF-β) on mitosis and enhance the secretion of HGF and epidermal growth factor (EGF), affecting mitoge...
