IEC-6 cells were exposed to increasing doses of gamma radiation and were treated with either vehicle, 3 μM LPA 18:1 or 10 μM OTP starting +30 min postirradiation. Colonies were counted on day 10 postirradiation. Both LPA- and OTP-treated cultures showed increased colony survival compared to vehicle-treated cultures at all radiation doses, as demonstrated by the slopes of the survival curves (regression fit R2 > 0.97 of colony survival, ANOVA for comparison of the slopes with Bonferroni post test, *P < 0.01).
