l-NMA and NAC inhibit tumor cell transmigration. MDA-mCherry cells were added to EAhy926 monolayers growing in Transwell filters and previously incubated with 300 µM l-NMA for 1 h or 2.5 mM NAC for 1.5 h. Transmigration was allowed for 6 h. Transwell inserts were removed, fixed, and mounted. MDA-mCherry cells were counted on the basal side of the transwell in random fields. T test, * p < 0.05 in comparison to control (C:transmigrating cells with any compound); n = 4
