A widely used model system to investigate cell proliferation is stimulation of serum-arrested cells with growth factors. Recent data suggest that there are two waves of growth factor-dependent signaling events required for a proliferative response. One is an acute burst of signaling, which occurs immediately after growth factor stimulation and lasts for 30 - 60 min. The other occurs in a different time frame (8-12 hrs post stimulation), and involves activation of cyclin dependent kinases (CDKs). In addition to a general overview of growth factor-dependent signaling, we present our "two wave" hypothesis for how signaling and cell cycle progression are linked.

Impact of Nutrients on the Cell Cycle of Saccharomyces cerevisiae

C. Theo Verrips

The length of G1 phase of S. cerevisiae is mainly determined by the flux of nutrients. However this relation is not linear, as below a growth limiting C-flux of about 20 fmol.cell-1.h-1, this C-flux...

The Role of Reactive Oxygen Species in G1 Phase Progression

Cristina Martinez Muñoz and Jan Andries Post

Reactive oxygen species (ROS) are produced during pathological conditions by phago- cytes. The function of these produced ROS is to kill microbes and neoplastic cells. At first sight it seems unl...

Role of Cyclins and Cyclin-Dependent Kinases in G1 Phase Progression

R. Curtis Bird

Cyclin and the cyclin dependent kinases (CDKs) are the principle regulators of cell cycle progression through activation of cell cycle checkpoints. These are the core of the complex that compose...

Role of RB/E2F in G1 Phase Progression

Amy S. Yee and Jean Y. J. Wang

The progression from G1 to S phase requires the de novo expression of genes that en code proteins and enzymes involved in DNA replication. Regulation of these S-phase genes is, therefore, an impo...

Regulation of Signaling and the Cell Cycle by Cell Interactions with the Extracellular Matrix

R.L. Juliano

Adhesive interactions with the extracellular matrix, mediated primarily by integrins and transmembrane proteoglycans, play a key role in regulating the G1 phase of the cell cycle. A primary aspe...

G1 Phase Control and Cell Differentiation

María J. Muñoz-Alonso and Javier León

Cell differentiation is usually accompanied by irreversible cell cycle exit. The G1 regula tory molecules have been shown to be exquisitely regulated during the differentiation process and in man...

Cell Cycle Regulation During G1 Phase in Yeast: Decisions, Decisions, Decisions

Curt Wittenberg and Karin Flick

Coordination of cell cycle events is essential for the faithful duplication of cellular com- ponents during proliferation as well as for the adaptability of cells and organisms to varying interna...

Roles of Cyclin Kinase Inhibitors in G1 Phase Progression

Angela L. Tyner and Andrei L. Gartel

Cell cycle progression is tightly controlled by cyclin/Cyclin dependent kinase (CDK) complexes. Two families of cyclin kinase inhibitors have been identified based on their structures and affini...

Restriction Points in the G1 Phase of the Mammalian Cell Cycle

Johannes Boonstra

Progression through the cell cycle of mammalian cells is dependent upon external factors such as growth- and extracellular matrix factors. On the other hand, cell cycle progres sion can be inhibi...

Regulation of G1 Phase of Yeast Cells by Stress

Enrique Herrero, María Angeles de la Torre, Jordi Torres and Gemma Bellí

Different environmental stresses, among them heat, hyperosmotic and oxidative ones, cause yeast cells to arrest at G1. The duration of the arrest is proportional to the intensity of the stress...
