Sequence-dependent interaction between radiation and AT-101. Radiation and AT-101 were applied either concurrently or sequentially at the indicated doses. In the sequential schedule, AT-101 was administered either 24 h before radiation or 24 h after radiation.a: UM-SCC-11B; b: VU-SCC-OE. Data presented are representative of at least two experiments in both cell lines
