AZT, een HIV-virusremmer (klik hier),
die overigens niet geheel zonder gevaren is,
lijkt vermenigvuldiging van het XMRV-virus te kunnen stoppen,
omdat XMRV op een essentieel onderdeel sterk overeenkomt met HIV.
Xenotropic murine leukemia virus-related virus is susceptible to AZT.

The xenotropic murine leukemia virus-related virus (XMRV)
is a human retrovirus,
recently isolated from
tissues of
prostate cancer patients
with impaired RNase L activity.
In this study,
we evaluated
10 licensed anti-HIV-1 compounds
for their activity against XMRV,
including protease inhibitors (PI),
nucleoside reverse transcriptase (RT) inhibitors (NRTI),
non-nucleoside RT inhibitors (NNRTI) and
an integrase inhibitor.
No PI affected XMRV production;
even high concentrations of Ritonavir failed
to inhibit the maturation of XMRV Gag polyproteins.
Among the NRTI, NNRTI and integrase inhibitors used in this study,
only AZT blocked XMRV infection and
replication
through inhibition of
viral reverse transcription.
This sensitivity of
XMRV
to AZT
may be explained by
the modest homology in
the motif D sequences of
HIV-1 and XMRV reverse transcriptases.
If XMRV becomes established as
an etiological agent for
prostate cancer or other diseases,
AZT may be useful for
preventing or
treating XMRV infections
in humans.
