Some authors will say that the restriction point and the G1/S checkpoint are one and the same, but more recent studies have argued that there are two different points in the G1 phase that check the progression of the cell. (wikipedia.org)
The G1/S checkpoint is the point between G1 phase and the S phase in which the cell is cleared for progression into the S phase. (wikipedia.org)
Regulatory signaling systems that control the progression of the CELL CYCLE through the G1 PHASE and allow transition to S PHASE when the cells are ready to undergo DNA REPLICATION. (umassmed.edu)
Cell cycle progression is faster in cells in which invadopodia are abolished (by Tks5 knockdown), evidenced by earlier induction of cyclins A and B. A close look at the regulators of G1 revealed that the overexpression of p27 kip1 , but not p21 cip1 , causes faster turnover of invadopodia and increased ECM degradation. (biorxiv.org)
Cell cycle progression is governed by a complex network of cyclin-dependent kinases that define not only the phase of the cell cycle, but also the timing of transitions between phases 13 . (biorxiv.org)

After a vertebrate cell has been in the G1 phase for about three hours, the cell enters a restriction point in which it is decided whether the cell will move forward with the G1 phase or move into the dormant G0 phase. (wikipedia.org)
The first restriction point is growth-factor dependent and determines whether the cell moves into the G0 phase, while the second checkpoint is nutritionally-dependent and determines whether the cell moves into the S phase. (wikipedia.org)

In addition, cell cycle distribution analysis revealed that G0/G1 phase arrest was induced following pristimerin treatment in CAL‑27 and SCC‑25 cells, which was strongly associated with upregulation of p21 and p27, coupled with downregulation of cyclin D1 and cyclin E. Meanwhile, pristimerin induced significant apoptosis of CAL‑27 and SCC‑25 cells, alongside decreased levels of caspase‑3 and specific cleavage of poly (ADP‑ribose) polymerase. (spandidos-publications.com)
The underlying mechanisms of these effects were primarily mediated by G 1 phase cell cycle arrest and inhibition of the mitogen-activated protein kinase (MAPK)/extracellular signal-regulate kinase 1/2 (Erk 1/2) and protein kinase B (Akt) signaling pathways. (spandidos-publications.com)
