title: Effects of Fe(3+)-tumor cell interaction on Ca(2+)-uptake by Ehrlich ascites tumor cells.
abstract: Fe3+ ions complexed by various ligands induce an increased Ca2+ uptake by Ehrlich carcinoma ascites cells that is proportional to the thermodynamic stability constant of the complex, and the greatest increase is observed with ferric lactate. The absence of ATPase inhibition showed by this ferric complex, suggests that an increased passive diffusion of Ca2+ due to structural modifications of the cell membrane is the most probable cause of this phenomenon.
