| Abstract: | Reorganization (disassembly) of the actin filaments in Ehrlich ascites tumor cells, either by hypotonic treatment in the presence of Ca2+ or by addition of cytochalasin B, results in activation of the Na+/K+/Cl- cotransport system. However, other regulatory processes, some of which may be dependent on an intact filament system, are responsible for the activation of the Na+/K+/Cl- cotransport system after cell shrinkage. |
