 Effect of treatment with X‐rays alone, ZSTK474 alone, or a combination of both agents on the proliferation of HeLa cells. The cells were prepared in 60‐mm dishes at various cell densities 1 day before X‐irradiation. For treatment with X‐rays alone, the cells were X‐irradiated (2 Gy) 1 day later (day 0). For treatment with ZSTK474 alone, 2 days later (day 1), the cells were exposed to 1 μM ZSTK474. For X‐rays + ZSTK474, the cells were treated with 1 μM ZSTK474 24‐h after 2 Gy X‐irradiation. The number of cells was counted on days 0, 1, 2, 3, 4, 5, and 8 under a microscope. The relative values of the number of the cells based on the number on the day of X‐irradiation (day 0) are shown.
