AKT1 and infection: Making use of permissive human fibroblast cells stably transduced with “tet-on” expression cassettes that enable myr-Akt expression to be induced with doxycycline (Dox), we expressed either myristoylated Akt1 (myr-Akt) or a “kinase-dead” K179M myr-Akt control (K179M) for 24 h prior to infection at an MOI of 1 with either of two different HCMV strains, AD169rv and TB40/E.
