Dihexa does not block aminoglycoside entry into hair cells. There was no significant difference in quantified GTTR fluorescence within neuromasts of animals treated with or without 1 μM Dihexa (t-test; p = 0.1158). Sample control neuromast with bright GTTR fluorescence (inset top) is qualitatively the same intensity as a neuromast treated with 1 μM Dihexa (inset bottom). Scale bar represents 10 μm and applies to both images. N = 8 animals per treatment, error bars represent ± s.e.m.
