We generated five different hairpin sequences directed against AKTIP and three against Ft1. Infection of human primary fibroblasts (HPFs) or mouse embryonic fibroblasts (MEFs) with these recombinant lentivectors (LV-shAKTIP and LV-shFt1; henceforth abbreviated as shAKTIP and shFt1) resulted in target mRNA reductions to less than 13% of the wild type levels as measured by Q-PCR (S1A and S1B Fig). This evidence concerns the gene AKTIP and infection.
