The G1/S repressor WHI5 is expressed at similar levels throughout the cell cycle
Objectives While it is clear that cells need to grow before committing to division at the G1/S transition of the cell cycle, how cells sense their growth rate or size at the molecular level is unknown.

The key event of liver regeneration initiation (LRI) is the switch of hepatocytes from the G0 phase to the G1 phase. This study aimed to use the data from large-scale quantitatively detecting and analyzing (LQDA) to reveal the regulation of hepatocytes ...

Critical Role for P53 in Regulating the Cell Cycle of Ground State Embryonic Stem Cells
Summary: Mouse embryonic stem cells (ESCs) grown in serum-supplemented conditions are characterized by an extremely short G1 phase due to the lack of G1-phase control. Concordantly, the G1-phase-specific P53-P21 pathway is compromised in serum ESCs. Here,

Altered G1 phase regulation in osteosarcoma [PDF]
Alterations in the normal cell cycle lead to abnormal cell proliferation and to tumor development. To explore the role of the cyclin D/Cdk4 complex and the retinoblastoma protein (pRb) in the growth and spread of osteoblastic osteosarcoma (OS), 40 tumor samples were selected. In 17 of these cases, lung metastases occurred during follow-up.

Mitotic UV irradiation induces a DNA replication-licensing defect that potentiates G1 arrest response. [PDF]
Cdt1 begins to accumulate in M phase and has a key role in establishing replication licensing at the end of mitosis or in early G1 phase. Treatments that damage the DNA of cells, such as UV irradiation, induce Cdt1 degradation through PCNA-dependent CRL4-

G1 Phase Lengthening During Neural Tissue Development Involves CDC25B Induced G1 Heterogeneity [PDF]
ABSTRACTWhile lengthening of the cell cycle and G1 phase is a generic feature of tissue maturation during development, the underlying mechanism remains still poorly understood. Here we develop a time lapse imaging strategy to measure the four phases of the cell cycle in single neural progenitor cells in their endogenous environment.

Chromosome-condensed G1 phase yeast cells are tolerant to desiccation stress
The budding yeast Saccharomyces cerevisiae is capable of surviving extreme water loss for a long time. However, less is known about the mechanism of its desiccation tolerance.

Influence of cell cycle phase on calcification in the coccolithophore Emiliania huxleyi [PDF]
Calcification of the cosmopolitan coccolithophore species Emiliania huxleyi was investigated in relation to the cell division cycle with the use of batch cultures.

Summary: Cells initiate fate decisions during G1 phase by converting extracellular signals into distinctive cell cycle kinetics. The DNA replication timing is determined in G1 phase; lengthened G1 and hastened S phases correlate with increased neurogenic

The properties of nerve cell precursors in hydra [PDF]
Two signals, the head activator and an injury stimulus, control differentiation of nerve cells from uncommitted stem cells in hydra [Th. Holstein, H. C. Schaller, and C. N. David, (1986) Dev. Biol. 115, 9–17].
