Figure 2: The ability to block stress is not innate to all retroviruses.

(a) Phylogenetic tree of major retrovirus families used in this study (env gene). (b) HeLa cells were transfected or infected with HIV-2, SIV, EIAV, FIV, MLV or RSV and 48 h later were exposed to PatA. Cells were stained for gp41(SIV), p30(MLV), CA(FIV/RSV), G3BP1 and eIF3b, as indicated. Squares represent regions of interest. Scale bar, 30 μm. (c) NIH3T3 cells were transfected with MLV DNA (top) or Cos-7 cells were transfected with SIV DNA (bottom) and at 48 h exposed to PatA. Cells were stained for gp41(SIV), G3BP1, p30 (MLV) and UPF-1 as indicated. Scale bar, 30 μm.
