AOH disrupted the cytoskeletal (F-actin) organization. F-actin microfilaments were contiguous along the apical cell border and formed a circumferential, double-banded structure under control conditions. Rapidly after AOH, the double-banded structure was lost and F-actin exhibited a diffuse distribution. Two days later, the distribution of F-actin was not limited to the cell border but instead was diffusely scattered throughout the cytoplasm. The F-actin distribution only partially recovered and its double-banded structure reappeared in some cells at Day 7.
