n.c., No significant change over control. aSamples treated with 150 μM BPA only were exposed for 25 hr; those treated with 20 mM KBrO3 only were exposed for 1 hr, then medium was replaced for 23 hr; and samples co-exposed to 150 μM BPA were exposed for 1 hr, then exposed to 150 μM BPA + 20 mM of KBrO3 for 1 hr, followed by exposure for 23 hr to 150 μM BPA only. bGene expression fold change was evaluated in comparison with untreated control with all p-values < 0.05.
