Employing the repeated infection strategy in B-13 cells (in the absence of DEX) using AdV-SGK1F resulted detectable increases in Sgk1/SGK1F kinase activity (Fig 2B); widespread increased expression of Sgk1/SGK1F in infected remaining viable cells (Fig 2C) and co-expression of CpsI with SGK1F-expressing cells (determined specifically using the N terminal tag sequence cloned into the protein) (Fig 2D). Here, SGK1 is linked to infection.
