  • Title: Characteristic incorporation of ganglioside GM3, which induces monocytic differentiation in human myelogenous leukemia HL-60 cells.
    Author: Nakamura M, Ogino H, Nojiri H, Kitagawa S, Saito M.
    Journal: Biochem Biophys Res Commun; 1989 Jun 15; 161(2):782-9. PubMed ID: 2735922.
    Abstract:
    Using tritiated gangliosides [( 3H]-GM3 and [3H]-GM1), characteristic incorporation of exogenous GM3 to HL-60 cells was demonstrated in association with differentiation induction. [3H]-GM3 was bound 4-5 times more than [3H]-GM1 was. Scatchard analysis revealed high and low affinity patterns of binding to the cells. The concentration of GM3 that caused growth inhibition and cell differentiation corresponded well to that which showed the bi-phasic binding pattern. It was strongly suggested that GM3, which induces monocytic differentiation, was characteristically bound and incorporated to the cells around the concentration which caused growth inhibition and cell differentiation.
