It is also of interest to note that in mouse, T-cell lymphoma-specific MoMLV integrations have been identified at the Fos/Jdp2/Batf locus [156], and that the Epstein-Barr nuclear antigen 2 (EBNA2) induces up-regulation of B-ATF in EBV infected human B-cells, leading to viral latency rather than entrance into the lytic cycle [157]. Here, BATF is linked to lymphoma.
