In reacting to news that their cherished heroes are tainted, the court of public opinion has transitioned through phases of denial, anger, and acceptance of reality.
CDKA genes are constitutively expressed throughout the cell cycle, and they interact with several cyclin proteins to regulate transition through phases of the cell cycle, including the germ cell cycle in Arabidopsis [ 75].
Most bacterial species use alterative sigma factors to coordinate widespread changes in their transcriptome as they transition through different phases of growth.
As nuclear staining intensity doubles when proliferating cells transition through the phases of the cell cycle, the G0/G1 subset's coefficient of variation (CV, representing the normalized measure of dispersion of single event signals) becomes critically important to distinguish the G0/G1 to S-Phase transition.
Although best appreciated for its role in G1 regulation, TORC1 additionally regulates the transition through other phases of the cell cycle.
An abundance of evidence in the literature supports the critical roles of YY1 in the transitions through the different phases of the cell cycle [1], [2], [63].
RNA was isolated from liver samples at various time-points of liver regeneration including the initial or priming phase (0.5, 2 hr) which allows rapid activation of transcription factors promoting G0-G1 transitiof of normally quiescent hepatocytes [15], transition through G1 phase (12, 24 hr) and S/G2/M (36, 42, 48 hr) phases (Figure 1).
Autoinducers may participate in growth phase transitions to stationary phase through sensing of cell density, as has been suggested from studies of E. coli batch cultures [39].
Cdk2 also plays a critical role in the transition through S phase and the S to G2 transition as well.
When I transitioned through a phase of intense anxiety from corporate life into following my passion for yoga, she was a rock to me.
In our studies, I-IUdR-mediated gene expression profiles demonstrate the apparent induction of genes involved in negative regulation of cell cycle via checkpoint control and down-regulation of genes implicated in cell transition through M phase and/or cytokinesis.
