PV-10 enhances the effect of irradiation.

Notes: Neuroblastoma cell lines SK-N-AS (A) and IMR5 (B) were pretreated with either PBS (vehicle control) or 50 µM PV-10 for 4 hours. Cells were then irradiated with 0.5, 1, or 2 Gy and cultured for a further 92 hours. Cell viability was measured by alamar blue assay. Mean percentages of cell viability calculated from three separate experiments and standard errors of the means are shown. Asterisks show significant differences, paired Student’s t-test, P<0.05.
