title: Ehrlich tumour cells: Ca(2+)-uptake modification by aluminium lactate.
abstract: Aluminium lactate provokes the same modification of 45Ca(2+)-uptake by Ehrlich ascites tumour cells as does ferric lactate. The increase of uptake is metal-complex concentration-dependent, and in contrast to ferric lactate, is only partially inhibited by albumin. Under the same experimental conditions, chromic lactate provoked no modification of that uptake. A plasma membrane rigidity increase provoked by coordination binding of aluminium to phospholipids is likely to be the main cause of Ca(2+)-uptake modification by aluminium lactate.
