ADH-induced water permeability: what role for the microtubular network?
1. ADH-induced intramembrane particle aggregates in the apical membrane of the epithelial cells are specifically related to water permeability in the epithelium. 2. Colchicine and nocadozole (both of which bind to tubulin) inhibit ADH-induced osmotic water flow in the amphibian bladder. 3. Microtubules may be involved in the translocation of the aggrephores prior to their insertion into the plasma membrane.
