Xenotropic murine leukemia virus related virus (XMRV) has been implicated in prostate cancer and chronic fatigue syndrome (CFS). Because XMRV is a retrovirus, it might be susceptible to antiviral drugs that are licensed for the treatment of AIDS. AZT (azidothymidine) was previously found to bloc... Read More
Deep under the Mediterranean Sea, small animals have been discovered that live their entire lives without oxygen and surrounded by 'poisonous' sulphides. Researchers writing in the open access journal BMC Biology report the existence of multicellular organisms (new members of the group Loricifer... Read More
Four drugs that are used to treat the AIDS virus HIV can also inhibit the replication of xenotropic murine leukemia virus-related virus (XMRV), a mouse virus that has been found in some patients with prostate tumors and chronic fatigue syndrome.
