Figure 6From: Variations in Mre11/Rad50/Nbs1 status and DNA damage-induced S-phase arrest in the cell lines of the NCI60 panel Summary of the ability of NCI60 cell lines to arrest in S-phase when incubated with SN38. Representation of the concentration of SN38 that arrested each cell line in mid-S phase as determined in Figure 5. The cell lines in which no arrest was observed are designated 100. HL60 cells underwent apoptosis rather than arrest so no number is assigned.Back to article page
