    Oncolytic virotherapy for cancer treatment utilizes viruses for selective infection and death of cancer cells without any adverse effect on normal cells. We previously reported that the human respiratory syncytial virus (RSV) is a novel oncolytic virus against androgen-independent PC-3 human prostate cancer cells.

    Is there any other virus can using for Oncolytic virotherapy? - Oncolytic viruses identified to date are: adenovirus, reovirus, herpes simplex virus (HSV), Newcastle disease virus (NDV), vaccinia virus, myxoma virus, influenza virus, measles virus, coxsackievirus and vesicular stomatitis virus (VSV) (Anticancer oncolytic activity of respiratory syncytial virus., http://www.ncbi.nlm.nih.gov/pubmed?term=Anti-cancer%20oncolytic%20activity%20of%20respiratory%20syncytial%20virus)

    Why also using xenograft, not only for cell-culture method? - A human prostate tumor xenograft model (30) was used to examine the oncolytic function of RSV in vivo (Figure 2). -We also investigated the efficacy of intraperitoneally (I.P) delivered RSV for causing tumor regression and determined that intraperitoneally injected RSV also rendered significant reduction in the tumor growth compared to the growth of control, medium-treated tumors (Figure 2c). The significant tumor regression by intraperitoneally delivered RSV is shown in Figure 2d. Similar results were obtained with tumors grown in the dorsal flank (Supplementary Figure S2). Therefore, the RSV-responsive restriction of tumor growth at two sites (ear and flank) demonstrates the versatility of RSV in conferring oncolysis in vivo at different anatomical regions.

    How Oncolytic virus control the inflammation? - Oncolytic virus treatment induced at least a twofold increase or decrease in the expression of 50 genes relative to expression in the PBS-treated tumors (Supplementary Table 1, available online). Of these 50 genes, 48 displayed an increase in expression in the oncolytic virus - treated tumors compared with the controltreated tumors, suggesting that oncolytic virus treatment induced an inflammatory response - To confirm the role of the immune response in oncolytic virus - induced vascular hyperpermeability, we evaluated changes in oncolytic virus - induced vascular leakage in tumor-bearing rats that had been treated with cyclophosphamide before oncolytic virus injection. In addition to its immunosuppressive effects, cyclophosphamide blocks infl ammation and reduces viral clearance, both of which increase the propagation of oncolytic viruses, thereby enhancing therapeutic effi cacy of oncolytic viruses.

    There is a new scientific discovery about the "oncolytic virus" which means attack a tumor. That discovery said that RSV-respiratory syncytial virus- is an oncolytic virus which can attack cancer tumor selectively. But, that paper has not published yet, so i find a paper about the oncolytic virus.

    It's really cool to think that we're spending all this time and money on nanotechnology in the medical field, when we already have biological nanotechnology at our fingertips-- if we can learn to use them (viruses) anyway. Perhaps in 100 years a virion will refer to a virus that can heal a cell vs. infect it.
