  3. g retroviruses in the 1950-60s, when the term oncornaviruses was used to denote their RNA virus origin. With the letters RNA removed, it now refers to any virus with a DNA or RNA genome causing cancer and is synonymous with tumor virus or cancer virus. The vast majority of human and animal viruses do not cause cancer, probably because of longstanding.
  4. Oncogenes are genes that cause cancer. Retroviruses contain oncogenes and cause cancer in animals and, perhaps, in man. The viruses have appropriated their oncogenes from normal cellular DNA by genetic recombination. Correspondingly, uninfected vertebrate cells contain a family of evolutionary conserved cellular oncogenes

  6. (This accident, which was of such benefit to science, brought no evolutionary benefit to the viruses themselves--they can reproduce and live even when they lose their oncogene through mutation.) Retroviruses remain vital tools for the isolation of oncogenes and for elucidating fundamental processes within human cells
  7. In this article is compiled the current knowledge about oncogenic retroviruses. Cancer is a disease that affects millions of people around the world. The findings of the researches indicate that viral factors cause cancer. Viral factors associated with cancer leads to uncontrolled and abnormal growth of cells by their oncogenesis mechanisms

Retroviruses with these genes (also called transforming viruses) are known for their ability to quickly cause tumors in animals and transform cells in culture into an oncogenic state. [20] The polyproteins are cleaved into smaller proteins each with their own function The discovery of viral oncogenes in retroviruses led to the finding that they are not unique to viruses and homologous genes (called proto-oncogenes) are found in all cells. Indeed, it is likely that the virus picked up a cellular gene during its evolution and this gene has subsequently become altered Although a number of oncogenic retroviruses are capable of inducing tumors in animals, their relevance to human disease is mainly their role in the discovery of oncogenes. Oncogenic DNA viruses, in contrast, are an etiological factor in a significant portion of human cancers Complex oncogenic retroviruses contain in their genome not only the basic genes of the aforementioned simple retroviruses, but also regulatory and supplemental genes in which they manipulate the host cell and its machinery. The studies of DNA oncogenic viruses lead to the discovery of tumor suppressor genes including RB and p53 erbB is the oncogene of avian retroviruses that induce an acute form of erythroid leukaemia called erythroblastosis.The discovery of one of these viruses, referred to as strain R, dates from 1935.

The cancers induced by these viruses are determined by the transduced host gene. Retroviruses that cause cancer at a low incidence do not contain inserted host information. Rather, they appear to cause cancer via mutation of the expression of potentially oncogenic host genes In PNAS, Kincaid et al. report the identification of five miRNAs encoded by the delta retrovirus bovine leukemia virus (BLV) that are expressed in BLV-transformed B cells. Interestingly, BLV uses RNA polymerase III (pol III) to directly transcribe the pre-miRNA hairpins that give rise to these viral miRNAs, thereby preventing the cleavage of viral genomic RNA and mRNA species as a result of pre-miRNA excision

In 1976 they published the remarkable conclusion that the oncogene in the virus did not represent a true viral gene but instead was a normal cellular gene, which the virus had acquired during replication in the host cell and thereafter carried along Three oncogenic mechanisms of retroviruses other than insertional mutagenesis are known: 1) transformation by viral oncogenes, 2) oncogenesis by accessory proteins such as Tax of human T-cell.

Under ideal conditions, a focus of transformed cells in culture originates from the infection of a single cell by a single viral particle. In such single infections, almost all acutely transforming oncogenic retroviruses fail to produce infectious progeny, although they convert a normal cell into a cancer cell More than 40 different highly oncogenic retroviruses have been isolated from a variety of animals, including chickens, turkeys, mice, rats, cats, and monkeys. All of these viruses, like RSV , contain at least one oncogene (in some cases two) that is not required for virus replication but is responsible for cell transformation Oncogenic retroviruses in animals and humans Burmeister, Thomas 2001-01-01 00:00:00 Retrovirology emerged as a branch of science at the beginning of the last century. However, a deeper insight into the pathology of retroviruses and retrovirus‐induced cancers could only be gained after the advent of modern biochemical and molecular biological techniques in the 1970s and 1980s In PNAS, Kincaid et al. (3) report the identification of five miRNAs encoded by the delta retrovirus bovine leukemia virus (BLV) that are expressed in BLV-transformed B cells.

Retroviruses have played profound roles in our understanding of the genetic and molecular basis of cancer. Jaagsiekte sheep retrovirus (JSRV) is a simple retrovirus that causes contagious lung. Retroviruses are capable of transforming cells in at least three different ways: (1) the process of insertional mutagenesis; (2) through capture and unregulated expression of a host cell proto-oncogene; and (3) certain retroviruses, eg, bovine leukemia virus, Jaagsiekte sheep retrovirus, and enzootic nasal tumor virus, include genes that encode protein products that are directly.

Viruses of the avian leukosis/sarcoma group (ALSV) and reticuloendotheliosis viruses (REV) are highly prevalent in chickens and turkeys and naturally cause tumors in them. Commercial chickens are positive for antibodies, and a proportion actually carry infectious virus. Virus may be present in chicken products and in eggs, thus human exposure is virtually universal Retroviruses are associated with a variety of diseases including an array of malignancies, immunodeficiencies and neurological disorders. In particular, studies of oncogenic retroviruses established.

Abstract: Retroviruses are a family of viruses that cause a broad range of pathologies in animals and humans, from the apparently harmless, long-term genomic insertion of endogenous retroviruses, to tumors induced by the oncogenic retroviruses and acquired immunodeficiency syndrome (AIDS) resulting from human immunodeficiency virus infection

Retroviruses having both DNA and RNA genomes (Human T-lymphotropic virus and hepatitis B virus) can also cause cancers. Viruses can become carcinogenic when they integrate into the host cell genome as part of a biological accident, such as polyomaviruses and papillomaviruses. Key Terms. oncogenic: Tending to cause the formation of tumors A strain of avian leukosis virus (ALV) belonging to a new envelope subgroup J was isolated in the UK in 1988 from meat-type chickens.The disease caused by the members of this subgroup has since spread very rapidly worldwide and has become one of the major problems facing the broiler meat industry Avian retroviruses lacking an oncogene, such as Rous‐associated virus 1 (RAV‐1), RAV‐2, and td mutants of Rous sarcoma virus (RSV), can nevertheless cause leukemias and other neoplastic diseases. During this process, viral DNA integrates near a cellular proto‐oncogene, such as c‐myc, and thus de‐regulates its expression. The virus RAV‐0, on the other hand, is known to be non.

Oncogenesis by retroviruses: old and new paradigm

The HTLV-1 was the first oncogenic human retrovirus to be discovered in 1977. There is no current cure for human retroviruses but there are available treatments like the antiretroviral therapy. Retroviruses are often described as either simple (sometimes called oncogenic or γ-retroviruses; e.g., the murine leukemia virus [MLV]) or complex (e.g., lentiviruses). The main difference between these subtypes is the presence of a number of accessory and regulatory genes in complex, but not simple, retroviruses (discussed further below) [4, 7] A genus of the family RETROVIRIDAE consisting of non-oncogenic retroviruses that produce multi-organ diseases characterized by long incubation periods and persistent infection. Lentiviruses are unique in that they contain open reading frames (ORFs) between the pol and env genes and in the 3' env region Human retroviruses. Six human retroviruses have so far been identified. All infect T cells. HTLV 1 - T-cell leukaemias/lymphomas, Tropical spastic paraparesis. HTLV 2 - No known pathology.

Gray* St. Jude Children's Research Hospital, Memphis, Tennesse Src: The Discovery of the First Proto-Oncogene. In 1951, a young graduate student named Howard Temin arrived at Caltech to pursue a project in fruit fly embryology. However, after only a few months, Temin became bored with fruit flies. He joined a neighboring animal virology lab and shifted his focus to the budding field of cancer biology HTLV-1 belongs to a class of viruses called retroviruses. These viruses use RNA (instead of DNA) for their genetic code. To reproduce, they must go through an extra step to change their RNA genes into DNA. Some of the new DNA genes can then become part of the chromosomes of the human cell infected by the virus

In a double stranded RNA form, retroviruses infect a host cell with their genome, and then are reverse transcribed into double stranded DNA, with the DNA then integrated into the home cell genome. When integrated into a host genome, a retrovirus is hard to detect and can lay dormant for prolonged periods, having no discernible effect on the host The majority of oncogenic retroviruses do not carry an oncogene in their genome (77, 104, 131, 136, 137). Such viruses are called nonacute retroviruses because the incubation period of the resulting neoplasia is usually several months. Nonacute retroviruses are replication competent To assess the oncogenic potential of EGFR kinase domain mutants, tumor-derived mutations were introduced into the wild-type human EGFR cDNA by site-directed mutagenesis. The resulting wild-type and mutant EGFR cDNAs were then cloned into the pBabe-Puro retroviral vector and transferred into NIH-3T3 cells by retroviral infection Non-Transforming Retroviruses: These viruses, unlike the acutely transforming retroviruses, take much longer to develop tumors as they are very slow-acting. Also, unlike acutely transforming retroviruses, they don't disrupt the normal cellular function by the insertion of a viral oncogene. They take the route of a different mechanism called called insertional mutagenesis

Mammalian genomes are scattered with thousands of copies of endogenous retroviruses (ERVs), mobile genetic elements that are relics of ancient retroviral infections. After inserting copies into the germ line of a host, most ERVs accumulate mutations that prevent the normal assembly of infectious viral particles, becoming trapped in host genomes and unable to leave to infect other cells Endogenous retroviruses are a source of enhancers with oncogenic potential in acute myeloid leukaemia.
