Effect of LY294002 on proliferation of human erythroid progenitors and UT7 cells.
Inhibition of PI 3-K/Akt pathway by LY294002 dramatically inhibits proliferation of both human erythroid progenitors and UT7 cells. D7 + 1 human erythroid progenitors and UT7 cells were cultured at 105/mL in serum-free medium with Epo at 2 U/mL, without or with LY294002 (at 50 μM) or rapamycin (at 50 ng/mL) for 48 hours. DNA synthesis was assessed by [3H] thymidine incorporation after 4 hours. Analysis is given as the mean of 3 separate experiments.
