Detailed Analysis of Apoptosis and Delayed Luminescence of Human Leukemia Jurkat T Cells after Proton Irradiation and Treatments with Oxidant Agents and Flavonoids

Figure 4

Apoptosis and cell-cycle distributions assessed at 6, 24, and 48 h after treatment of Jurkat cells with the vehicle (Ctrl), with 50 μM QC for 1 h (QC), with 2 Gy of proton radiation (IR), or with 2 Gy of proton radiation after preincubation with 50 μM QC for 1 h (QC + IR). Apoptotic rates (a), G₀/G₁ (b), S-phase (c), and G₂/M (d) cell fractions are illustrated. The star denotes significant difference between the treatments: IR and QC + IR.
