Abstract-
Xenotropic murine leukemia virus-related virus (XMRV) was first
reported in 2006 in a study of human prostate cancer patients with
genetic variants of the antiviral enzyme, RNase L.
Subsequent
investigations in North America, Europe, Asia and Africa have either
observed or failed to detect XMRV in patients [prostate cancer,
chronic fatigue syndrome-myalgic encephalomyelitis (CFS-ME),
immunosuppressed with respiratory tract infections] or normal, healthy
control individuals. The principal confounding factors are the near
ubiquitous presence of mouse derived reagents, antibodies and cells,
and often XMRV itself, in laboratories. XMRV infects and replicates
well in many human cell lines, but especially in certain prostate
cancer cell lines.
XMRV also traffics to prostate in a non-human
primate model of infection. Here we will review the discovery of XMRV
and then focus on prostate cancer related research involving this
intriguing virus.
