Activation of MSRV-Env expression requires protein kinase C activity. (A) Schematic representation of putative phosphorylation sites within CD46-Cyt1 and Cyt2 and candidate kinases and their inhibitors (PKC: Protein Kinases C; CK-2: Casein Kinase 2). (B,E,H) Transactivation controls. (C,D) Effect of bisindolylmaleimide 5 μM (BIM) on HHV-6A-induced MSRV-Env expression; (F,G,I,J) absence of the effect of, Apigenin 40 μM and Scr-inhibitor 5 μM on MSRV-Env expression. The expression of MSRV-Env was analyzed by immuofluorescence, using anti-MSRV Env mAb, followed by anti-mouse-Alexa 555 (red staining, arrowhead) and representative images from 3 independent experiments were presented. DAPI (blue staining) was used to visualize cell nuclei, bar = 50 μm.
