(2011, September 23). Due to the high number of MLV sequences in the mouse genomic DNA, we found it prudent to test for mouse DNA contamination in our samples. The HHS-supported study examined the validity of testing techniques intended to detect the presence of several viruses, xenotropic murine leukemia virus-related virus (XMRV) or related polytropic murine leukemia viruses (P-MLVs). This finding, ... of CFS patients, failed to confirm evidence for HTLV (type 1 …

The protein bands on the gel were electrophoretically transferred to a polyvinylidene difluoride (PVDF) membrane (invitrogen). Science. Jiangqin Zhao, Vincent C. Lombardi, To ensure that this did not compromise results in the new study, extensive efforts were undertaken to avoid laboratory contamination and contamination of samples. However, screening the genomic DNA from peripheral blood lymphocytes of both healthy control and CFS cohorts, we did detect PCR products that were identical to XMRV gag sequences, as well as other MLV gag sequences. Participating in the project were seven laboratories, each of which analyzed a panel of blinded blood samples to determine whether MLV retroviruses were present in them. Note: Content may be edited for style and length. Approximately 30 mL of blood were drawn into three heparinized tubes (Becton Dickinson) and shipped overnight (CFS patients) or processed immediately (healthy controls). Recent animal studies showed that XMRV infection elicited a potent humoral immune response in rhesus macaques [22]. The study also checked for evidence of contamination with mouse DNA, because XMRV or its predecessors may be present in some mouse strains and cell lines. reported their startling finding that the gammaretrovirus xenotropic murine leukemia virus-related retrovirus (XMRV) is present in 67% of blood samples of patients suffering from chronic fatigue syndrome (CFS), as opposed to only 3.7% of samples from healthy individuals. The PBMCs were collected from the interface following the spin and were used for DNA isolation. To clarify this issue, we tested our plasma samples for the presence of XMRV-specific antibodies. We are committed to sharing findings related to COVID-19 as quickly as possible. The cohort comprised a combination of those with an abrupt and others with a gradual onset of symptoms. The 36 healthy individuals (15 females and 21 males) were recruited on a voluntary basis by the Huber laboratory and were between 18 and 65 years of age. The assays demonstrated excellent sensitivity, detecting early seroconversion bleeds in XMRV-infected rhesus macaques [22]. In October 2009 Vincent Lombardi and Judy Mikovits from Whittemore Peterson Institute (WPI) in Reno and colleagues first reported -- also in Science-- that nearly 70% of patients with CFS (sometimes known as myalgic encephalomyelitis)had evidence of xenotropic murine leukemia virus-related virus, or XMRV, in their peripheral blood mononuclear cell samples, compared with just 4% of healthy control subjects. "XMRV, related viruses not confirmed in blood of healthy donors or chronic fatigue syndrome patients." ScienceDaily. Review articles are excluded from this waiver policy. Two labs, which previously had reported the association of XMRV with chronic fatigue syndrome, reported the presence of XMRV for some samples. D., the paper's lead author, compiled the blood samples and distributed them to participating laboratories. Walid Heneine, None of the 148 plasma samples were reactive in the p15E CMIA (Figure 1(a)). Judy A. Mikovits, Using both a test developed by the Switzer lab at CDC for mouse mitochondrial DNA [14], as well as a test developed by the Coffin lab for the IAP [17], we found that every sample that was positive for XMRV or other MLVs PCR products was also positive for mouse DNA. 2011 Nov 11;334(6057): 814-7. Science 333(6050): 1694-1701. The initial reports of a link between XMRV and chronic fatigue syndrome prompted HHS to investigate how well tests detect XMRV/P-MLVs, and the prevalence and potential transmission of these viruses in the blood supply. The May 31, 2011, advance online edition of Science, for example, featured 2 such studies -- one by pioneering HIV/AIDS researcher Jay Levy -- prompting the journal's editor-in-chief to issue an "Editorial Expression of Concern.". "The study also checked for evidence of contamination with mouse DNA, because XMRV or its predecessors may be present in some mouse strains and cell lines.". Questions? : Failure to confirm XMRV/MLVs in the blood of patients with chronic fatigue syndrome: A multi-laboratory study. Assay positive controls were derived from XMRV-infected macaque plasmas at 1 : 1000 (PC1) or 1 : 4000 (PC2).

2011; 334:814–817. The discovery of a new virus that could infect humans lead Lombardi et al. Simmons G, Glynn SA, Komaroff AL, et al. Although some support linking XMRV or MLVs and CFS has been published [3, 5, 6], it has been overshadowed by reports failing to detect the virus in CFS patients [7–20], including a study done by us. Kui Gao, Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. The combination of negative molecular and serologic data do not support an association between CFS and XMRV or other MLVs. Although 2 samples from the same healthy control had weak reactivity in gp70 CMIA, the reactivity was not confirmed by recombinant gp70 WB.

A pool of normal human plasma was used as negative control (NC) and as sample diluents. Crossref, Medline, Google Scholar; 28. Science 2011;334:814–817. Additional tests run in the same and other laboratories on the same samples did not find XMRV, strongly suggesting that these persons were negative for XMRV/ P-MLVs. Partial retraction. The HHS press release added that W. Ian Lipkin, MD, at Columbia University’s Mailman School of Public Health is leading a separate study testing fresh blood samples from 150 people living with CFS and 150 healthy controls.

Shyh-Ching Lo, ... in the US were infected with a novel gamma retrovirus, xenotropic murine leukaemia virus-related virus (XMRV), a virus previously linked to prostate cancer. Kathryn S. Hagen, 6th European AIDS Conference (EACS 2017)

The link has prompted some researchers to explore treating CFS patients with Ampligen, an immune modulator once tried in people with HIV/AIDS prior to the advent of combination antiretroviral therapy.

Cohen J: Chronic fatigue syndrome researcher fired amidst new controversy. Such follow-up studies are standard in science to determine whether earlier findings are accurate. As shown in Figure 2, both samples showed no visible WB bands using either XMRV viral lysate proteins (Figure 2(a)) or recombinant gp70 protein (Figure 2(b)). Indira K. Hewlett, The following labs and investigators were responsible for testing the sample panels: W. Ian Lipkin, M.D., of Columbia University's Mailman School of Public Health, is currently leading a separate study that is testing fresh blood samples from 150 people living with chronic fatigue syndrome and 150 similar but healthy people. September 22, 2011. Through this effort, organizers will process, blind, and send samples to laboratories at the FDA, the CDC, and the WPI for testing for the presence of XMRV, MLV or related viruses. Failure to confirm XMRV/MLVs in the blood of patients with chronic fatigue syndrome: a multi-laboratory study. If the viruses had been proven to be present in patients with chronic fatigue syndrome or healthy donors, concerns were raised that these viruses could put the blood supply at risk. Daniel L. Peterson, www.sciencedaily.com/releases/2011/09/110922164208.htm (accessed November 1, 2020). In summary, the serologic data obtained in this study suggests a lack of XMRV infection in our CFS patients and healthy controls. Francis W. Ruscetti, Initially reactive specimens were retested in duplicate by either ARCHITECT p15E or gp70 CMIAs. In June 2010, the AABB, a nonprofit U.S. blood banking association, recommended that collection centers discourage people with chronic fatigue syndrome from donating blood. "The results of this study, along with other recent findings, reassure us that these viruses do not pose a threat to the safety of the nation’s blood supply,” stated Susan Shurin, MD, acting director of the National Heart, Lung, and Blood Institute of the National Institutes of Health. John M. Coffin,
