Infection of cells with deletion of the DNA polymerase gene Polß was similar to infection of Myh and Ogg1 null cells (Figure 3C, HIV P<0.0001, MMLV P = 0.31, FIV P<0.0001), suggesting that the BER pathway significantly affects lentiviral infection but not gammaretroviral infection. Here, MUTYH is linked to infection.
