Transcript levels of these genes increase at the same time, shortly before the expression of histone genes, but after the cessation in cell cycling caused by mutations in CDC28 (25) or exposure to a...Johnston, L. H. (1990). Periodic events in the cell cycle. Curr Opin Cell Biol 2,...
Smith and Martinproposed the transition probability (TP) model to explain the significance of the variability of the cell cycle length of individual cells within a clone or culture. This postulates that the cell cycle length consists of a fixed period of time, which is the same for all members...
Rac1 accumulates in the nucleus during the G2 phase of the cell cycle and promotes cell division Rac1 regulates a wide variety of cellular processes. The polybasic region of the Rac1 C terminus functions both as a plasma membrane--targeting motif and a... D Michaelson,W Abidi,D Guarda...
cells are not uniformly distributed in lineages, as shown by permutation tests, but appear to emerge from asymmetric divisions taking place at non-stochastic levels: a parent cell influences with 95% confidence and 0.5% error the unequal partitioning of the cell cycle duration in its two ...
coliandB. subtilis, tightly regulate cell cycle progression to achieve consistent cell size distributions and replication dynamics. Many of the hallmark features of these model bacteria, including lateral cell wall elongation and symmetric growth and division, do not occur in mycobacteria. Instead, ...
Furthermore, HSV infection prevented the normal G1 increases in cyclin D1 and D3 protein levels, and blocked the normal G1 appearance of new electrophoretic forms of cdk2 and cdk4. Thus, HSV infection inhibits several events that normally occur in the cell cycle during G1 phase, arguing ...
The repertoire of fos and jun pro- teins expressed during the G1 phase of the cell cycle is de- termined by the duration of mitogen-activated protein kinase activation. Mol Cell Biol 1999;19:330-41 Curran T, Bravo R, Muller R. Transient induction of c-fos and c-myc in an immediate...
Chronology of events in the first cell cycle of the polyspermic egg of the domestic fowl (Gallus domesticus) The nuclear population in the polyspermic egg of the domestic hen was examined in whole-mount preparations of the germinal disc. The numbers of nuclei vari... D Waddington,C Gribbin...
It is well known that microtubule-damaging agents suppress microtubule dynamics, leading to disruption of the mitotic spindle in dividing cells, cell cycle arrest at M-phase, and the late apoptosis [ 1 ]. A better understanding of the processes coupling microtubule damage to the onset of ...
We show here that mitotic degradation of Myf5 is conserved in non-myogenic cells, and is thus strictly under the control of the cell cycle apparatus. Using Xenopus egg extracts as an in vitro system to dissect the main steps of Myf5 mitotic proteolysis, we show that (1) Myf5 stability is...
