title: Differential hemoglobin synthesis in murine erythroleukemic cells: hemin effects.
abstract: The addition of butyric acid to murine erythroleukemic cells (clone T3Cl2) induced the cells to differentiate, producing adult hemoglobin (A, alpha 2,beta 2) and an embryonic hemoglobin (E2, alpha 2Y2). The subsequent addition of hemin to the differentiating cells increased the synthesis of adult hemoglobin four-fold and the synthesis of embryonic hemoglobin two-fold; the relative synthesis of the alpha and beta globins increased more than the y globin. The embryonic hemoglobin was expressed prior to the adult hemoglobin in differentiating cells.
