Li, Y., Butenko, Y. & Grafi, G. Histone deacetylation is required for progression through mitosis in tobacco cells.
The p42 mitogen-activated protein kinase (MAPK) is required for progression through meiotic M phase in Xenopus oocytes.
Arsenate-induced uterine hyperplastic lesions also showed a strong upregulation of cyclin D1, an estrogen-associated gene product essential for progression through the G1 phase of the cell cycle.
The industries we so often rail against - 'the media', 'fashion', 'politics' - they are all made up of people and that in itself offers an opportunity for progression through compromise.
We are about to commence another more expansive field trial containing our RGA2 lines, as well as many more new Cavendish (cultivars Williams and GN) lines transformed with RGA2, to identify lines that are suitable for progression through to commercial release.
It is also responsible for the proteolytic maturation of diverse polypeptide precursors and for the spatial and temporal regulation of the degradation of many key cell regulators whose destruction is necessary for progression through essential processes, such as cell division, differentiation and, more generally, adaptation to environmental signals.
It's not that they're especially difficult to get into, as such; but there are barriers for progression through each set of experiences, wilfully esoteric tangents of patience-testing singularity.
As such, it is required for progression through mitotic checkpoints, double strand DNA repair, telomere repair, apoptosis and meiosis [2].
In summary, phosphorylation of SIRT1 by cyclinB/Cdk1 is necessary for progression through the cell cycle, apparently by facilitating entry into G2.
The only strong hit in category I was RRM2, a subunit of ribonucleotide reductase that is essential for progression through S-phase.
This should have resulted in cells undergoing G0 G1 arrest since the protein is responsible for progression through the G0 G1/S phase transition [40].
