a

HMEC were treated with WR1065 (SH) for 30 min, irradiated, and plated for survival.

b

HMEC were treated with WR1065 (SH) for 30 min, washed to remove the drug, irradiated 24 h after drug treatment, and plated for survival.

c

Average from three separate experiments.

d

Comparison between cells irradiated with 2 Gy and cells treated with WR1065 (SH) and then irradiated. P values were calculated using a two-tailed t test.
