International ME/CFS and FM Awareness Day is May 12: The World Will Know
Did you know that May 12 belongs to us? Lots of us are aware of this. We share the buzz on it amongst ourselves. We add blue ribbons to profile pictures. We raise our voices, join our hands, mount the few podiums available to us and tug at the sleeve of the rest of the world.

    Two positives - one Prostate Cancer, one Healthy Control. Can people please stop saying there's no XMRV in Europe.....

    BACKGROUND: We previously identified a novel exogenous gammaretrovirus (xenotropic murine leukemia virus-related gammaretrovirus (XMRV)) using a pan-viral microarray. XMRV is the first MLV-related virus found in human infection. Forty percent (8/20) of familial prostate cancer patients homozygous for a mutation in RNase L (R462Q) were positive for XMRV, while the virus was rarely (1/66) detected in familial prostate cancer patients heterozygous for R462Q or carrying the wild type allele. OBJECTIVES: To determine the presence of XMRV in non-familial prostate cancer samples. STUDY DESIGN: RNA from prostate tissue was analyzed for XMRV using nested RT-PCR. In all samples, RNase L (R462Q) genotyping was performed using an allele-specific PCR. RESULTS: XMRV-specific sequences were detected in one of 105 tissue samples from non-familial prostate cancer patients and from one of 70 tissue samples from men without prostate cancer. The two XMRV-positive patients were wild type or heterozygous for the R462Q mutation and thus carried at least one fully functional RNase L allele. CONCLUSIONS: XMRV was rarely detected in non-familial prostate cancer samples from Northern European patients. The homozygous mutation R462Q (QQ) was significantly underrepresented (<6%) in this cohort when compared to other studies (11-17%).

    Thanks for posting this! It's reassuring! We just have to sit back (or lie back) and wait things out....WPI will come out in the lead yet again....~FernRhizome
