Since the gamma/gamma + beta globin expression ratio represented the major difference between neonatal and adult erythroblasts (58 +/- 12 vs. 7 +/-3, respectively), we tested the hypothesis that PKCalpha might affect gamma-globin expression by measuring the levels of (A)gamma- or beta-promoter-driven reporter activity in erythroid cells stably (GM979) or transiently (K562, primary adult and neonatal erythroblasts) transfected with a dual microLCRbetaprRluc(A)gammaprFluc reporter in the presence of transient expression of either the constitutively active (sPKCalpha) or catalytically inactive (iPKCalpha) PKCalpha. As further control, GM979 cells were incubated with the PKC inhibitor rottlerin (30 microM). In all the cells analyzed, sPKCalpha significantly increased (by two-to sixfold) the levels of luciferase activity driven by the (A)gamma-promoter and the (A)gamma-F/((A)gamma-F + 2beta-R) expression ratio. In GM979 cells, rottlerin inhibited (by 50%) the (A)gamma-driven luciferase activity and the (A)gamma-F/((A)gamma-F + 2beta-R) expression ratio. These results suggest that different PKC isoforms may exert ontogenetic-specific functions in erythropoiesis and that modulation of PKCalpha might affect the activity of (A)gamma-promoter-driven reporters."xsd:string |
