ابزارهای گوناگونی به منظور انتقال ژن به سلول های یوکاریوتی توسعه یافته اند، در میان آن ها، کارایی ویروس های rna دار متعلق به خانواده رتروویریده به دلیل الحاق پایدار ژنوم خود در کروموزوم های میزبان بالاتر است. ویروس لوکمی موش (mlv) شناخته شده ترین عضو جنس اورتورتروویرینا از گامارتروویروس ها است. ناقل ویروسی بر پایه mlv تنها قادر به بیان ژن های خارجی در سلول های در حال تقسیم میتوز می باشد، که بیا...
Some of the earliest studies of retroviral integration targeting reported that sites of gammaretroviral DNA integration were positively correlated with DNase I-hypersensitive sites in chromatin. This led to the suggestion that open chromatin was favorable for integration. More recent deep sequencing experiments confirmed that gammaretroviral integration sites and DNase I cleavage sites are asso...
We recently reported identification of a previously undescribed gammaretrovirus genome, xenotropic murine leukemia virus-related virus (XMRV), in prostate cancer tissue from patients homozygous for a reduced activity variant of the antiviral enzyme RNase L. Here we constructed a full-length XMRV genome from prostate tissue RNA and showed that the molecular viral clone is replication-competent. ...
A key step in proliferation of retroviruses is the conversion of their RNA genome to double-stranded DNA, a process catalysed by multifunctional reverse transcriptases (RTs). Dimeric and monomeric RTs have been described, the latter exemplified by the enzyme of Moloney murine leukaemia virus. However, structural information is lacking that describes the substrate binding mechanism for a monomer...
BACKGROUND Xenotropic murine leukemia virus-related virus (XMRV) was generated after a recombination event between two endogenous murine leukemia viruses during the production of a prostate cancer cell line. Although the associations of the XMRV infection with human diseases appear unlikely, the XMRV is a retrovirus of undefined pathogenic potential, able to replicate in human cells in vitro. S...
Rabbi t antisera raised against rabbit corneal (SIRC) cells infected with xenotropic murine leukemia virus (MuLV) 1 contain antibodies specific for antigens related to the major glycoproteins (gp70) o f the xenotropic M u L V envelope (1). These antigens appear to be normal constituents of the cell surface o f lymphoeytes of all inbred mice and have been termed XenCSA-xenotropic M u L V envelop...
