Targeting the cell-cycle checkpoints: constructing a safe and potent oncolytic adenovirus To induce S-phase entry in the host cell to support their replication,adenovirusesexpress early region 1A protein (E1A) that binds and inactivatesRb protein, which regulate the G1–S-phase cell-cycle checkpo...
The accurate transition from G1 phase of the cell cycle to S phase is crucial for the control of eukaryotic cell proliferation, and its misregulation promotes oncogenesis. During G1 phase, growth-dependent cyclin-dependent kinase (CDK) activity promotes DNA replication and initiates G1-to-S ...

elevated E2F-1 activity was sufficient to arrest a substantial subset of cells in S phase and this effect was correlated to and dependent on the induction of p21 protein. Since E2F proteins control genes required for cell cycle progression and are activated by various oncogenic events, we beli...
We have studied the transcription of the CTP:phosphocholine cytidylyltransferase α (CTα) gene in C3H10T1/2 fibroblasts as a function of the cell cycle. The cells were incubated for 48 h with 0.5% fetal bovine serum. The cells were induced into the G1 phase of the cell cycle by the ...
2023年1月5日,来自美国斯坦福大学医学院的Tobias Meyer团队在Molecular Cell杂志在线发表了题为CDT1 inhibits CMG helicase in early S phase to separate origin licensing from DNA synthesis的文章,揭示了细胞如何在S早期确保DNA只复制一次。研究人员发现S...
Whatever the source of the message, the cell receives the signal, and a series of events within the cell allows it to proceed into interphase. Moving forward from this initiation point, every parameter required during each cell cycle phase must be met or the cycle cannot progress. ...
Phosphatidylcholine synthesis increases in C3H10T1/2 fibroblasts during the G1 and S phases of the cell cycle. Previous studies demonstrated that the mRNA encoding CTP:phosphocholine cytidylyltransferase α (CTα) increases during S phase (Golfman, L. S., Bakovic, M., and Vance, D. E. (...
