To investigate the effects of mA3 and hA3G on XMRV as well as MoMLV infection in more detail, we transiently transfected 293T cells in the presence of MoMLVgag or XMRVgag together with LTR-luc, pHCMV-XMRVenv and increasing amounts of Apobec expression plasmids in the range from 25ng to 1μg. Here, PNMA3 is linked to infection.
