    This statement in the discussion may be worthy of note: “XMRV-induced cytokine release does not appear to be tumor epithelial cell specific...”

    Looks like the XMRV is ramping up the cancer.

    Yes. Impressive little ability considering xmrv is a recently created chance contaminant.

    I wonder how this links:

    IDENTIFICATION OF A NOVEL RETROVIRUS IN PATIENTS WITH BENIGN PROSTATIC HYPERPLASIA

    oh btw (even though retroviruses couldn´t possibly be causing neuroimmune diseases :rolleyes: ) osteopontin is significantly raised in autism, and its levels correlate to severity of symptoms ...

    (From the paper) -" mice naturally do not develop PC"

    anciendaze pointed this out on another forum.
    Looks as if the mice could be immune to whatever is causing the PC- (remember they have evolved to be without the xpr1 receptor.)

    "We provide evidence that the gammaretrovirus XMRV significantly contributes to tumorigenesis of 22Rv1 xenografts in mice. These observations are supported by in vitro results demonstrating differences in cytokine release in 22Rv1 cells infected with XMRV and 22Rv1 cells with reduced viral transcripts. Furthermore, we provide evidence that XMRV infection in prostate stromal fibroblasts significantly induces changes in cytokine release"
    ...."In summary, our results indicate that the transforming capacity of 22Rv1 cells is strongly dependent on the presence of XMRV. "

    "BPH virus: A retrovirus identified in prostate samples from subjects with BPH.The BPH virus is distinct (for example at the nucleic acid or amino acid level) from XMRV"

    From the above O'Keefe patent..(Thanks Nastasia.) Did we miss this patent when it was published? I dont remember it.

    From Wiki -
    "Osteopontin (OPN) is expressed in a range of immune cells, including macrophages, neutrophils, dendritic cells, and Tand B cells, with varying kinetics. OPN is reported to act as an immune modulator in a variety of manners. Firstly, it has chemitactic properties, which promote cell recruitment to inflammatory sites. It also functions as an adhesion protein, involved in cellattachment and wound healing In addition, OPN mediates cell activation and cytokine production, as well as promoting cell survival by regulating apoptosis"
