  • Title: Aluminum ions stimulate DNA synthesis in quiescent cultures of Swiss 3T3 and 3T6 cells.
    Author: Smith JB.
    Journal: J Cell Physiol; 1984 Mar; 118(3):298-304. PubMed ID: 6321524.
    Abstract:
    Micromolar concentrations of AI3+ are shown to be strongly mitogenic for quiescent cultures of Swiss 3T3 and 3T6 cells. AI3+ caused a striking shift in the dose-response curve for the effect of fetal bovine serum on 3H-thymidine incorporation. In the absence of serum the mitogenic effect of aluminum was greatly potentiated by insulin or cholera toxin, but not epidermal growth factor or 12-0-tetradecanoyl-phorbol-13-acetate. The stimulation of DNA synthesis was maximal by 15-20 microM AI3+ X AI3+ at 100 microM had no inhibitory effect on DNA synthesis. AI3+ had no significant effect on cellular cyclic adenosine monophosphate in the presence or absence of insulin or an inhibitor of cyclic nucleotide phosphodiesterases.
