Clonogenic survival assay demonstrating the radiosensitizer capacity of SAHA. MCF7, SCC-25 and TK6 cell lines were treated with 0.0 μM (●), 0.5 μM (■) and 1.0 μM (▲) of SAHA for 24 h and then exposed to graded doses of ionizing radiation. Each point on the survival curve represents the surviving fraction ± SE from three separate experiments. Error bars are shown unless smaller than the symbol size.
