title: Human leukemic cells: receptor binding and biological effects of insulin and insulin-like growth factors.
abstract: Receptor binding and biological effects of insulin and insulin-like growth factors I and II (IGF I/II) were assessed in three human malignant cell lines: a Burkitt-type ALL-cell line, a ANLL-cell line and a Hodgkin's disease-cell line. Insulin receptor binding could be demonstrated in Burkitt-type ALL cells and ANLL cells, whereas no insulin receptor binding was detectable in Hodgkin cells. IGF I and IGF II binding could be demonstrated in all leukemic cells. Insulin stimulated glycogen synthesis in the insulin receptor bearing cell lines. DNA synthesis was stimulated by insulin, IGF I and II. IGF I was more active in stimulating DNA synthesis than IGF II.
