Modelling radiation-induced cell cycle delays [PDF]
Ionizing radiation is known to delay the cell cycle progression. In particular after particle exposure significant delays have been observed and it has been shown that the extent of delay affects the expression of damage such as chromosome aberrations.

The contribution of age structure to cell population responses to targeted therapeutics [PDF]
Cells grown in culture act as a model system for analyzing the effects of anticancer compounds, which may affect cell behavior in a cell cycle position-dependent manner. Cell synchronization techniques have been generally employed to minimize the variation in cell cycle position.

Cell Cycle Commitment and the Origins of Cell Cycle Variability [PDF]
Exit of cells from quiescence following mitogenic stimulation is highly asynchronous, and there is a great deal of heterogeneity in the response. Even in a single, clonal population, some cells re-enter the cell cycle after a sub-optimal mitogenic signal while other, seemingly identical cells, do not, though they remain capable of responding to a ...

Mechanisms of Cellular Senescence: Cell Cycle Arrest and Senescence Associated Secretory Phenotype
Cellular senescence is a stable cell cycle arrest that can be triggered in normal cells in response to various intrinsic and extrinsic stimuli, as well as developmental signals.

Copper induces cell death by targeting lipoylated TCA cycle proteins
Copper is an essential cofactor for all organisms, and yet it becomes toxic if concentrations exceed a threshold maintained by evolutionarily conserved homeostatic mechanisms. How excess copper induces cell death, however, is unknown.

Cell cycle regulation: p53-p21-RB signaling
The retinoblastoma protein RB and the transcription factor p53 are central tumor suppressors. They are often found inactivated in various tumor types. Both proteins play central roles in regulating the cell division cycle. RB forms complexes with the E2F

‘Dividing cells pass through a regular sequence of cell growth and division, known as the cell cycle’, according to a college textbook of biology published in 1983 [[1][1]], 5 years before the underlying principles of control were first laid bare during 1988, the annus mirabilis of cell ...

The Influence of Cell Cycle Regulation on Chemotherapy
Cell cycle regulation is orchestrated by a complex network of interactions between proteins, enzymes, cytokines, and cell cycle signaling pathways, and is vital for cell proliferation, growth, and repair.

Mouse Chd4-NURD is required for neonatal spermatogonia survival and normal gonad development
Testis development and sustained germ cell production in adults rely on the establishment and maintenance of spermatogonia stem cells and their proper differentiation into spermatocytes.
