SF3A2 and infection: (A) Quantitative RT-PCR and (B) Western blot showing the expression of SF3A2 in human CD34+ cells five days post-infection with the respective lentiviral shRNAs targeting SF3A2 (sh1-4) and a control luciferase gene (shLUC). (C) Growth curves showing that downregulation of SF3A2 results in reduced total cell numbers during erythroid differentiation from three independent experiments.
