General description

A cell-permeable triazolo-diamine compound that displays anti-proliferative properties in various human cancer cells (IC50 = 20 nM, 35 nM and 92 nM in HCT-116, HeLa, and A375 cells, respectively). Acts as a highly potent, reversible, ATP-competitive inhibitor of Cdk1/cyclin B and Cdk2/cyclin A (IC50 = 600 pM and 500 pM, respectively) with selectivity over VEGF-R2 (IC50 = 32 nM), GSK-3β (IC50 = 140 nM), and a panel of eight other kinases (IC50 ≥ 1 µM).

Cell differentiation involves profound changes in global gene expression that often has to occur in coordination with cell cycle exit. Because cyclin-dependent kinase inhibitor p27 reportedly regulates proliferation of neural progenitor cells in the subependymal neurogenic niche of the adult mouse

External signaling controls cell-cycle entry until cells irreversibly commit to the cell cycle to ensure faithful DNA replication. This process is tightly regulated by cyclin-dependent kinases (CDKs) and the retinoblastoma protein (Rb). Here, using live-cell sensors for CDK4/6 and CDK2

Contact inhibition of cell proliferation regulates tissue size and prevents uncontrolled cell expansion. When cell density increases, contact inhibition can force proliferating cells into quiescence. Here we show that the variable memory of local cell density experienced by a mother

The G1-S checkpoint is thought to prevent cells with damaged DNA from entering S phase and replicating their DNA and efficiently arrests cells at the G1-S transition. Here, using time-lapse imaging and single-cell tracking, we instead find that DNA damage
