Fig. 4From: PREB inhibits the replication of prototype foamy virus by affecting its transcriptionInhibition of PFV replication by PREB 329–418 aa. (A) Truncations of PREB protein. (B–D) HEK293T cells were transfected with pcPFV, the empty vector or PREB and different truncations. After 48 h, culture supernatants (600 µl) (B) or 1/20 transfected HEK293T cells (C) were co-cultured with PFVL cells. Luciferase activity was measured 48 h post-infection. (D) The rest HEK293T cells were lysed for Western blot analysis. *** P<0.001, **** P<0.0001 and ns for P > 0.05Back to article page
