		It is equivalent to Cdc28 in budding yeast, and to Cdk1 in mammals.
		In mammals, the cell cycle is initiated by the binding of Cyclin D (CycD) to Cdk4 or Cdk6.
		The final phase is catalyzed by the binding between Cyclin B (CycB) and Cdk1.

		Phase III cells were identified as those having gone through four or five divisions, and phase IV cells were defined as those having divided in excess of six times.
		Phases III and IV consisted of cells dividing between four and five divisions or greater than six divisions, respectively, by the end of the 14-day period (Fig 5).
		In contrast, whereas 70% of phase III and IV cells expressed cyclin E, only 38% of phase II cells expressed this cyclin suggesting that proliferation of these cells may be arrested via a mechanism involving the downregulation of the expression of cyclin E rather than the upregulation or over-expression of p27.

	On the proposal of a G0 phase and the restriction point -- Cooper 12 (3): 367 -- The FASEB Journal
		G1 phase cells delayed in division are proposed to be in a `postmitotic' state (G1pm); those later in the G1 phase (in these experiments, cells older than 3.5 h) are in a `presynthetic' (G1ps) phase of the division cycle.
		Cells that enter the S phase (indicated by the shaded area) during this treatment are now defined as being in the G1ps phase.
		Cells in any phase of the division cycle have the same pattern of continued synthesis: a plateau giving a delay in mass increase and recovery to the original rate of mass synthesis.

		The conventional wisdom then, and until a few years ago was that, because T cells are highly specific (they only recognize one antigen among the millions possible), they would remain quiescent until they saw their precise antigen and would be driven through the cell cycle by pathways that regulate the cell cycle machinery.
		Resting T cells are actively maintained the G0 phase of the cell cycle by negative regulatory molecules (shown in red).
		Progression through the Restriction point “R” of the G1 phase and transition to the S phase are similarly dependent on the orderly occurrence of biochemical events, including sustained activity of CDK4 and CDK2 that inactivate Rb and promote transition to the S phase.

		Cells in each phase of the cell cycle (G1, S, and G2/M phases indicated by the different shadings on the horizontal bar) are related in size to the particular cell cycle phases.
		When cells are starved, the resulting population of cells with a G1 phase amount of DNA is proposed to be arrested at a point in the cell cycle (a) such as the restriction point or arrested in some out-of-cycle phase (b) such as G0.
		Whereas all the cells may have a G1 phase amount of DNA, the cells represented in the middle panel are not at any particular point in the cell cycle but are representative of all parts of the cell cycle.

		The nucleus is removed from a G0 phase arrested cell (left).

		From the G0 state the cell has the option of differentiation (developing a specific structure) or re-entering the G1 phase and then the S phase leading to cell division.
		During this phase structures to be used in cell division are synthesized.
		Following the lag phase is the log (exponential) phase, during which, the number of cells in the population increases exponentially with time.

		This metabolic switch is followed by a second slow-growing phase during which ethanol, acetate and other products of the initial fermentation process are being used as carbon sources.
		Independently of the studies on meiosis, Rim15 was also isolated as a protein that specifically interacted with the Tps1 subunit of the trehalose synthase complex [20,21].
		Although direct phosphorylation of the transcription factors by Rim15 is conceivable, Rim15 may alternatively regulate the establishment of physiological context-specific interactions between these factors and the general transcription machinery [25] or activate transcription from Msn2/4- and Gis1-dependent promoters through chromatin remodeling [26,27].

		In the early 1970s, the nature and duration of the G0 phase were a source of controversy - indeed, some had even proposed that G0 did not really exist.
		He showed that cells re-enter the cell cycle by transiting a 'restriction point' - after which they are committed to the cell cycle - and argued that this switch is defective in cancer cells.
		Eleven years later, in a seminal paper, Zetterberg and Larsson followed the behaviour of individual cells by time-lapse microscopy to provide a detailed map of cell responses to serum starvation, cyclohexamide treatment or exposure to particular growth factors.

		G0/G1 arrest and S phase inhibition of human cancer cell lines by inositol hexaphosphate (IP6).
		METHODS: The anti-proliferative effect of IP6 was evaluated using dual-parameter flow cytometric measurements of DNA content, versus the incorporation of 5-bromo-2-deoxyuridine (BrdU) to determine cells actively synthesizing DNA.
		Combined analysis of the expression of cell cycle-related proteins, proliferation marker Ki-67 and proliferating cell nuclear antigen (PCNA) versus DNA content were used to determine the amount of proliferating cells in each phase, engaged in cell cycle transit.
