Figure 2From: The Akt-inhibitor Erufosine induces apoptotic cell death in prostate cancer cells and increases the short term effects of ionizing radiationApoptosis induction in response to ErPC3 and ionizing radiation. PC3 and LNCaP cells were treated with 1-50 µM ErPC3 or irradiated with a single dose of 2 or 10 Gy. 48 h later, cells were stained with propidium iodide in a hypotonic citrate buffer containing Triton X-100 and subjected to flow cytometric analysis to estimate DNA fragmentation which occurs upon induction of apoptosis. 5 µM ErPC3 were sufficient to induce DNA fragmentation in PC3 cells (A), whereas 25 µM ErPC3 were required to trigger apoptotic DNA-fragmentation in LNCaP cells (B). Ionizing radiation up to 10 Gy did not induce DNA-fragmentation above a background level in PC3 (C) and LNCaP cells (D).Back to article page
