Effect of MeHg on migration-related genes. HTR8/SV-neo cells were treated with 0, 0.01, 0.1, or 1 μg/mL MeHg for 24 hours (N=3 replicates x 2 duplicates). Quantification of cdh3 and ctnnb1 by RT-PCR revealed decreased expression relative to control treatment (horizontal line). cdh3 was downregulated more by lower doses of MeHg, specifically 0.01 μg/mL (**** denotes p<0.0001). MeHg decreased expression of ctnnb1 in a dose-dependent manner, with the decreases caused by 0.1 and 1 μg/mL being significant (* denotes p<0.05).
