Alsterpaullone, a Cyclin-Dependent Kinase Inhibitor, Mediated Toxicity in HeLa Cells through Apoptosis-Inducing Effect

Figure 4

Effects of alsterpaullone on the cell cycle in HeLa cells. Blue arrow: G₂/M cell cycle arrest; red arrow: sub-G₁ increase indicating apoptosis occurred. HeLa cells were sensitive to alsterpaullone and arrested in G₂/M prior to undergoing apoptosis.
