Figure 4

Effects of pTpT on cell cycle and apoptosis in vitro. A. Jurkat cells were exposed to pTpT (100 μM) or pApA (100 μM) in vitro and cell cycle analysis performed after 1 and 24 hours by flow cytometry as described in Materials and Methods. Results show representative histograms from five independent experiments. Note that only pTpT stalls the cell cycle, not pApA, and no increase in apoptotic sub-G1 DNA content was observed with either pTpT or pApA. B. Bar graph showing percentage of cells in each phase of the cell cycle in cells treated with pTpT or pApA for 24 hrs.
