In this study, siRNA complementary to 5′ region of exon II of α-globin mRNA was examined for its role in erythroid colony forming cells (ECFCs) isolated from normal peripheral blood donor. On day 6 of cell culture, 1 × 106ECFCs were transfected with lipofectamine-containing α-globin specific siRNA. After 48 h of transfection, α-globin specific siRNA produced significantly reduction of α-globin mRNA level in a dose-dependent manner, but it did not affect the level of β-globin mRNA. Significantly, decreased numbers of hemoglobinized erythroid cells relative to the control were observed supporting the inhibitory effect of this α-globin mRNA specific siRNA. © 2008 Elsevier Inc.
