Clonogenic assay in HEC-1-B cells after radiation exposure.

<p>Knockdown of YAP expression by siRNA reduced clonogenic survival in HEC-1-B cells, resulting in an increase in radiation sensitivity with a dose enhancement factor at 10% survival (DEF 0.1) of 1.36. Results are shown in means ±standard deviations (bars) in triplicate experiments. Similar trends were obtained in other three independent experiments.
