Eif4a3 is required by neurula stages for movement. A: Glucocorticoid receptor-Eif4a3 fusion construct. B: Addition of dexamethasone (DEX) allows nuclear entry of GR-Eif4a3. C: Addition of DEX at or before stage 17 to embryos injected with Eif4a3MO+GR-Eif4a3 RNA rescues the embryonic touch response, scored at stage 32; diminished rescue or lack of rescue is seen with DEX addition at later stages. DEX addition prior to stage 8 showed similar rescue to that seen from stages 8-17 (data not shown).
