In short term transfections, neither protein induced substantial apoptosis or cell cycle arrest.
As noted above, the stable balance between the two cell fractions suggests no substantial difference in cell cycle rate between them.
In particular, it can generate a substantial variability in the cell cycle [ 5].
It is accompanied by substantial biochemical changes including cell cycle exit [ 36], changes in metabolism [ 37, 38] and alteration in structural proteins [ 39, 40].
However, their expression changes in the original microarray data are often neglectable and do not show substantial variation across the cell cycle.
We would respectfully argue that the figures and the data contained therein are of substantial value to the cell cycle community, as this study is the first to document phosphorylation in a large‐scale manner in a minimally perturbed mammalian system, and the first to examine the cell cycle gene expression in this cell lineage.
3-[E- 4-fluorostyryl)]-2-chloroquinoline (compound 7B) caused substantial DNA damage and arrested cell cycle in S phase.
Notably, the perturbed genes did not overlap significantly with E2F4 bound genes, and inspection of the perturbed sets of genes revealed no substantial functional category enrichment (including cell cycle and proliferation), thereby suggesting that these perturbations are not directly caused by removal of E2F4.
Conversely, in the clones with substantial chromosomal changes, pathways of cell cycle control and DNA damage response were downregulated from early to late passages (Table 2).
Cell cycle was evaluated using flow cytometry in A549, H460, and H226 cells treated with 5 μM B[a]P and/or 5 μM vorinostat: vorinostat did have a substantial effect on G1-S cell cycle arrest.
