abstract = {The consumption of bovine milk and meat is considered a
risk factor for colon- and breast cancer formation, and milk
consumption has also been implicated in an increased risk
for developing Multiple Sclerosis (MS). A number of highly
related virus-like DNAs have been recently isolated from
bovine milk and sera and from a brain sample of a MS
patient. As a genetic activity of these
Acinetobacter-related bovine milk and meat factors (BMMFs)
is unknown in eukaryotes, we analyzed their expression and
replication potential in human HEK293TT cells. While all
analyzed BMMFs show transcriptional activity, the MS brain
isolate MSBI1.176, sharing homology with a transmissible
spongiform encephalopathy-associated DNA molecule, is
transcribed at highest levels. We show expression of a
replication-associated protein (Rep), which is highly
conserved among all BMMFs, and serological tests indicate a
human anti-Rep immune response. While the cow milk isolate
CMI1.252 is replication-competent in HEK293TT cells,
replication of MSBI1.176 is complemented by CMI1.252,
pointing at an interplay during the establishment of
persistence in human cells. Transcriptome profiling upon
BMMF expression identified host cellular gene expression
changes related to cell cycle progression and cell viability
control, indicating potential pathways for a pathogenic
involvement of BMMFs.},
