Identification of key residues in subgroup A avian leukosis virus envelope determining receptor binding affinity and infectivity of cells expressing chicken or quail Tva receptor. (1/162)

To better understand retroviral entry, we have characterized the interactions between subgroup A avian leukosis virus [ALV(A)] envelope glycoproteins and Tva, the receptor for ALV(A), that result in receptor interference. We have recently shown that soluble forms of the chicken and quail Tva receptor (sTva), expressed from genes delivered by retroviral vectors, block ALV(A) infection of cultured chicken cells ( approximately 200-fold antiviral effect) and chickens (>98% of the birds were not infected). We hypothesized that inhibition of viral replication by sTva would select virus variants with mutations in the surface glycoprotein (SU) that altered the binding affinity of the subgroup A SU for the sTva protein and/or altered the normal receptor usage of the virus. Virus propagation in the presence of quail sTva-mIgG, the quail Tva extracellular region fused to the constant region of the mouse immunoglobulin G (IgG) protein, identified viruses with three mutations in the subgroup A hr1 region of SU, E149K, Y142N, and Y142N/E149K. These mutations reduced the binding affinity of the subgroup A envelope glycoproteins for quail sTva-mIgG (32-, 324-, and 4,739-fold, respectively) but did not alter their binding affinity for chicken sTva-mIgG. The ALV(A) mutants efficiently infected cells expressing the chicken Tva receptor but were 2-fold (E149K), 10-fold (Y142N), and 600-fold (Y142N/E149K) less efficient at infecting cells expressing the quail Tva receptor. These mutations identify key determinants of the interaction between the ALV(A) glycoproteins and the Tva receptor. We also conclude from these results that, at least for the wild-type and variant ALV(A)s tested, the receptor binding affinity was directly related to infection efficiency.  (+info)

Role of calcium in protein folding and function of Tva, the receptor of subgroup A avian sarcoma and leukosis virus. (2/162)

Tva is the cellular receptor for subgroup A avian sarcoma and leukosis virus (ASLV-A). The viral receptor function of Tva is determined by a 40-residue cysteine-rich motif called the LDL-A module. In this study, we expressed and purified the wild-type (wt) Tva LDL-A module as well as several mutants and examined their in vitro folding properties. We found that, as for other LDL-A modules, correct folding and structure of the Tva LDL-A module is Ca2+ dependent. When calcium was present during in vitro protein folding, the wt module was eluted as a single peak by reverse-phase high-pressure liquid chromatography. Furthermore, two-dimensional nuclear magnetic resonance (NMR) spectroscopy gave well-dispersed spectra in the presence of calcium. In contrast, the same protein folded in vitro in the absence of calcium was eluted as multiple broad peaks and gave a poorly dispersed NMR spectrum in the presence of calcium. The calcium affinity (Kd) of the Tva LDL-A module, determined by isothermal titration calorimetry, is approximately 40 microM. Characterization of several Tva mutants provided further evidence that calcium is important in protein folding and function of Tva. Mutations of the Ca2+-binding residues (D46A and E47A) completely abrogated the Ca2+-binding ability of Tva, and the proteins were not correctly folded. Interestingly, mutations of two non-calcium-binding residues (W48A and L34A) also exerted adverse effect on Ca2+-dependent folding, albeit to a much less extent. Our results provide new insights regarding the structure and function of Tva in ASLV-A entry.  (+info)

Isolation and characterization of nuclear RNA polymerase II from chicken myeloblastosis cells. (3/162)

Nuclear RNA polymerases of chicken myeloblastosis cells were solubilized and fractionated by diethylaminoethyl-Sephades A25 column chromatography. Both alpha-amanitin-insenstitive (polymerase I) and- sensitive (polymerase II) species were isolated. Polymerase activity, contained two peaks of enzyme (IIa and IIb), which were further purified by glycerol gradient centrifugation. The partially purified enzymes were characterized by their requirement of four nucleoside triphosphates and metal ions and by their sensitivity to several inhibitors. The enzymes were compared with RNA polymearases derived from normal chickent bone marrow cells,and the total extractable myeloblastosis than in bone marrow cells. Polymearse II from both cell types was shown to be sensitive to cytosine arabinoside triphosphate inhibiton.  (+info)

Avian erythroleukemia: a model for corepressor function in cancer. (4/162)

Transcriptional regulation at the level of chromatin plays crucial roles during eukaryotic development and differentiation. A plethora of studies revealed that the acetylation status of histones is controlled by multi-protein complexes containing (de)acetylase activities. In the current model, histone deacetylases and acetyltransferases are recruited to chromatin by DNA-bound repressors and activators, respectively. Shifting the balance between deacetylation, i.e. repressive chromatin and acetylation, i.e. active chromatin can lead to aberrant gene transcription and cancer. In human acute promyelocytic leukemia (APL) and avian erythroleukemia (AEL), chromosomal translocations and/or mutations in nuclear hormone receptors, RARalpha [NR1B1] and TRalpha [NR1A1], yielded oncoproteins that deregulate transcription and alter chromatin structure. The oncogenic receptors are locked in their 'off' mode thereby constitutively repressing transcription of genes that are critical for differentiation of hematopoietic cells. AEL involves an oncogenic version of the chicken TRalpha, v-ErbA. Apart from repression by v-ErbA via recruitment of corepressor complexes, other repressors and corepressors appear to be involved in repression of v-ErbA target genes, such as carbonic anhydrase II (CAII). Reactivation of repressed genes in APL and AEL by chromatin modifying agents such as inhibitors of histone deacetylase or of methylation provides new therapeutic strategies in the treatment of acute myeloid leukemia.  (+info)

Heterophil function and resistance to staphylococcal challenge in broiler chickens naturally infected with avian leukosis virus subgroup J. (5/162)

Avian leukosis virus subgroup J has a high tropism for myeloid lineage cells and frequently induces neoplastic transformation of myelocytes. The impact of congenital avian leukosis virus subgroup J infection on the function of circulating heterophils and susceptibility to staphylococcal infection was investigated. Six-week-old broiler chickens negative for exogenous avian leukosis viruses or congenitally infected with avian leukosis virus subgroup J were inoculated intravenously with 10(6) colony-forming units of Staphylococcus aureus, and pre- and postinoculation heterophil function was assessed. All chickens developed a leukocytosis with heterophilia after inoculation, but total leukocyte and heterophil counts were significantly higher in leukosis-negative chickens than in virus-infected chickens. Tenosynovitis was more severe in leukosis-negative chickens, and 2/10 (20%) of the virus-infected chickens had no histologic evidence of tenosynovitis. Osteomyelitis in the tibiotarsus or tarsometatarsus developed in 5/10 (50%) of the chickens in each group. S. aureus was recovered from the hock joint of 6/10 (60%) of the chickens in each group. Heterophils from all chickens exhibited similar phagocytic ability pre- and postinoculation. Heterophils from virus-infected chickens exhibited less bactericidal ability preinoculation than did heterophils from leukosis-negative chickens. However, postinoculation bactericidal ability was similar in both groups. Avian leukosis virus subgroup J provirus was present in heterophils isolated from congenitally infected chickens. Heterophils isolated from broiler chickens congenitally infected with avian leukosis virus subgroup J exhibit no significant functional deficits, and infected and uninfected chickens exhibit similar susceptibility to staphylococcal infection.  (+info)

Localization of avian leukosis virus subgroup J in naturally infected chickens by RNA in situ hybridization. (6/162)

The novel subgroup J of avian leukosis virus (ALV-J) has emerged as a significant cause of myeloid neoplasia and weight suppression in broiler chickens. We investigated viral tropism using RNA in situ hybridization (ISH) in naturally infected chickens. Formalin-fixed tissues were collected from 12-day-old embryos (seven infected, two control) and from 0-week-old (four infected, one control), 3-week-old (five infected, one control), 6-week-old (five infected, one control), and 9-week-old (10 infected, two control) chickens naturally infected with ALV-J in ovo. A 636-base antisense riboprobe complementary to the 3' and 5' ends of the pol and env viral genes, respectively, was constructed. Strong positive staining was present in cardiac myocytes, Purkinje fibers, vascular and pulmonary smooth muscle, renal glomeruli, distal tubules, and pituitary glands. Light staining was present in gastrointestinal smooth muscle, thyroid and adrenal glands, and follicular medullae in the cloacal bursa. Staining was not present in any hematopoietic precursors. Tissues from newly hatched chicks exhibited the strongest and most consistent staining, whereas staining in embryos was minimal. RNA ISH confirmed the presence of ALV-J-specific nucleic acid within cytoplasmic inclusions in cardiac myocytes, Purkinje fibers, pituitary glands, and renal glomeruli. Viral tropism for cardiac myocytes and Purkinje fibers may relate pathogenetically to the cardiomyopathy and congestive heart failure described in index chicken flocks infected with ALV-J. Viral tropism for endocrine organs may relate pathogenetically to the weight suppression associated with infection.  (+info)

Avian bic, a gene isolated from a common retroviral site in avian leukosis virus-induced lymphomas that encodes a noncoding RNA, cooperates with c-myc in lymphomagenesis and erythroleukemogenesis. (7/162)

bic is a novel gene identified at a common retroviral integration site in avian leukosis virus-induced lymphomas and has been implicated as a collaborator with c-myc in B lymphomagenesis. It lacks an extensive open reading frame and is believed to function as an untranslated RNA (W. Tam, Gene 274:157-167, 2001; W. Tam, D. Ben-Yehuda, and W. S. Hayward, Mol. Cell. Biol. 17:1490-1502, 1997). The oncogenic potential of bic, particularly its ability to cooperate with c-myc in oncogenesis, was tested directly by expressing c-myc and bic, either singly or in pairwise combination, in cultured chicken embryo fibroblasts (CEFs) and in chickens using replication-competent retrovirus vectors. Coexpression of c-myc and bic in CEFs caused growth enhancement of cells. Most importantly, chick oncogenicity assays demonstrated that bic can cooperate with c-myc in lymphomagenesis and erythroleukemogenesis. The present study provides direct evidence for the involvement of untranslated RNAs in oncogenesis and provides further support for the role of noncoding RNAs as riboregulators.  (+info)

Cardiomyopathy in broiler chickens congenitally infected with avian leukosis virus subgroup J. (8/162)

Dilated cardiomyopathy and ascites in broiler chickens are frequently associated with rapid growth and pulmonary hypertension, but can be associated with some avian leukosis virus (ALV) infections. The novel subgroup J of ALV has a high cardiac tropism, but dilated cardiomyopathy has not been reported previously. We report a dilated cardiomyopathy incidence of 11.1% in broiler chickens congenitally infected with ALV subgroup J (ALV-J). Gross lesions included severe body weight suppression, cardiomegaly with biventricular dilation, right ventricular hypertrophy, visceral congestion, and ascites. Cardiac myocytes and Purkinje fibers contained 2- to 10-microm intracytoplasmic magenta inclusions that contained ALV-J-specific nucleic acid. Ultrastructurally, inclusions contained ribosomes and immature virions and were associated with myofibril disruption and disarray. Peracute centrilobular hepatic necrosis was present in most cases. ALV-J-associated cardiomyopathy may involve a direct viral effect on cardiac myocytes and Purkinje fibers.  (+info)

Subgroups A, B, E and J are the major subgroups of avian leukosis virus (ALV) infecting chickens. ALV infection has become endemic in China and has a significant negative effect on the poultry industry. Consequently, there is an urgent need for a specific, sensitive and rapid method for diagnosis and eradication of ALV. Therefore, we developed a simple and rapid real-time loop-mediated isothermal amplification (LAMP) reaction for the timely detection of the common ALV subgroups, whereby the amplification can be obtained in 35 min under isothermal conditions at 63 °C, ability to specific, sensitive and rapid detect all the common ALV subgroups. A set of four specific primers was designed to target the sequences of the pol gene of ALV, and the loop-mediated isothermal amplification (LAMP) assay were developed and compared with PCR and virus isolation methods. The results from specificity of the LAMP assay showed that only target ALVs DNA was amplified. The LAMP assay demonstrated a sensitivity of 20

Morbidity is low but mortality high. Mortality tends to be chronically higher than normal for a prolonged period. Egg production is somewhat reduced. There may be increased susceptibility to other infectious diseases due to damage to the immune system. Vertical transmission is most important by infection of the egg white in infected breeders (who are long-term carriers), lateral transmission is poor but infection may occur by the faecal-oral route, especially in young birds. In lymphoid leukosis the incubation period is about 4-6 months; it may be as short as 6 weeks for some of the other manifestations. The causative viruses are rapidly inactivated at ambient temperature and on exposure to most disinfectants ...

Quantitative Evaluation of DNA Methylation Patterns for ALVE and TVB Genes in a Neoplastic Disease Susceptible and Resistant...Quantitative Evaluation of DNA Methylation Patterns for ALVE and TVB Genes in a Neoplastic Disease Susceptible and Resistant...
Chicken endogenous viruses, ALVE (Avian Leukosis Virus subgroup E), are inherited as LTR (long terminal repeat) retrotransposons, which are negatively correlated with disease resistance, and any changes in DNA methylation may contribute to the susceptibility to neoplastic disease. The relationship between ALVE methylation status and neoplastic disease in the chicken is undefined. White Leghorn inbred lines 72 and 63 at the ADOL have been respectively selected for resistance and susceptibility to tumors that are induced by avian viruses. In this study, the DNA methylation patterns of 3∼6 CpG sites of four conserved regions in ALVE, including one unique region in ALVE1, the promoter region in the TVB (tumor virus receptor of ALV subgroup B, D and E) locus, were analyzed in the two lines using pyrosequencing methods in four tissues, i.e., liver, spleen, blood and hypothalamus. A significant CpG hypermethylation level was seen in line 72 in all four tissues, e.g., 91.86±1.63% for ALVE region2 in blood,

Anti avian leukosis virus P27 protein monoclonal antibody / clone # 5E1-1F1 - Antibodymall
Avian sarcoma leukosis virus (ASLV) is an endogenous retrovirus that infects and can lead to cancer in chickens; experimentally it can infect other species of birds and mammals. ASLV replicates in chicken embryo fibroblasts, the cells that contribute to the formation of connective tissues. Lymphoid leukosis is the most common form of this disease and with typical presentation of gradual onset, persistent low mortality, and neoplasia of the bursa. Subgroups A, B, E and J are the major subgroups of avian leukosis virus (ALV) infecting chickens. ALV infection has become endemic in many countries and has a significant negative effect on the poultry industry.. ...

HPRS-103, the prototype of avian leukosis virus (ALV) subgroup J, was isolated in 1989 from meat-type chickens from commercial flocks where it induces myelocytic myeloid leukosis (ML). The HPRS-103 env gene differs considerably from other ALV subgroups but shows high identity (75-97%) to env-like sequences of the different members of the EAV family of endogenous avian retroviruses. Recently, we have isolated several viruses related to HPRS-103 from cases of ML. Although these isolates showed properties of ALV subgroup J, the majority of them resisted neutralization by HPRS-103-specific serum, suggesting antigenic variation. The nucleotide sequence of the env gene of the variant viruses showed several substitutions resulting in amino acid changes especially clustered in the variable regions hr1, hr2 and vr3. Analysis of the data suggests that selection pressure, probably from the immune response, is driving the antigenic variation among the isolates. Phylogenetic analysis of the sequences showed the

Leukosis & BVD - Minnesota Dairy Herd Improvement AssociationLeukosis & BVD - Minnesota Dairy Herd Improvement Association
Bovine Leukosis is a disease caused by the Bovine Leukosis virus (BLV). This is a blood borne disease that dwells in the lymphocytes (white blood cells) in cattle. Only 5% of infected animals will exhibit the clinical symptoms of developing tumors in lymphatic tissue. The prevalence ofleukosis is wide spread. It is fairly common to find herds with a prevalence of 80-90%, however not very common to find herds that are completely free of leukosis. According to the NAHMS 96 study, 88.5% of dairy herds and 38.7% of beef herds are infected. Transmission occurs by the transfer of bodily fluids that contain infected white cells (blood, colostrum, milk). Anything from reusing without sanitizing contaminated needles, syringes, breeding sleeves, dehorners, or balling guns can transmit leukosis. Transmission can also occur through colostrum or to a fetus in utero. ...

Virus-Host Interactions in the Development of Avian Leukosis Virus-Ind by Rosalinda Gram FosterVirus-Host Interactions in the Development of Avian Leukosis Virus-Ind by Rosalinda Gram Foster
Avian leukosis virus (ALV)-induced osteopetrosis is a proliferative disorder of the bone affecting the growth and differentiation of osteoblasts. Osteopetrosis is a polyclonal disease in which cells of the bone contain, on average, multiple viral DNA copies. Osteopetrotic bone is also characterized by the accumulation of unintegrated viral DNA, suggesting an atypical life cycle of the virus in the infected osteoblasts. To better understand virus-host interactions in the induction of osteopetrosis by ALVs, infected chick osteoblast cultures and osteopetrotic bone were examined for aspects of the virus life cycle and effects of infection on osteoblast function. Levels of infection and virus expression were compared in cultured osteoblasts and osteopetrotic bone. Osteopetrotic bone contained higher levels of viral DNA and correspondingly higher levels of viral proteins than infected osteoblast cultures, suggesting a higher viral load in the diseased bone. A significant level of mature Gag protein was

National Zoological Gardens launches recycling pilot projectNational Zoological Gardens launches recycling pilot project
South Africas largest zoo, the National Zoological Garden of South Africa (NZG), on Wednesday launched a recycling pilot project aimed at job creation and addressing the massive litter problem which its thousands of annual visitors leave in their wake.. Should the programme prove successful, it could also be rolled out at the Mokopane Biodiversity Centre in Limpopo.. The pilot project, which was founded in conjunction with the national PET Recycling Company (PETCO) and the City of Tshwane, will be operated by the Umkariso Women in Water cooperative.. The NZGs acting manager for commercial services and business development, Marcel Singh, said five previously unemployed Tshwane residents had been trained and appointed to collect and sort the high volumes of recyclable materials generated daily by the zoos restaurants, curio shops, offices, research facilities, animal kitchens and veterinary hospital.. ...

The product of the insertionally activated c-erbB locus lacks the extracellular ligand-binding domain and is strictly leukemogenic. It has previously been demonstrated that the disease spectrum associated with aberrant c-erbB expression can be expanded by structural perturbation of the cytoplasmic domain of this protein. In this report, we use mutagenesis and retroviral vectors to identify specific mutations in the carboxyl-terminal domain of the insertionally activated c-erbB product that are sufficient to activate the sarcomagenic potential of this protein. ...

On the Nomenclature of Viruses Associated with AIDS [1985]On the Nomenclature of Viruses Associated with AIDS [1985]
Traditionally, virus isolates have been named most commonly for the disease from which they were isolated - e.g. influenza, poliomyelitis, visna, foot-and-mouth disease, and the like. A smaller number are named for the place of isolation - Coxsackie, Sindbis, and Sendai viruses are a few examples, and a mercifully small number are named for their discoverers - alone or in combination with other features - such as Epstein-Barr virus, Rous sarcoma virus, etc. With retroviruses, it is also usual to append the species of origin to the name - avian leukosis virus, human T-cell lymphoma virus, baboon endogenous virus, etc. Unlike most other organisms, the naming of new virus isolates has usually been a trivial prerogative of the isolator, and not subject to review by other workers in the field . This has, in general, caused little difficulty so long as the names chosen were novel and did not presuppose unproven relationships. Significant confusion has been created in the past, however, by injudicious ...

A team led by Xin Li, Ph.D., assistant professor in the departments of Biochemistry and Biophysics and Urology at the University of Rochester School of Medicine and Dentistry, analyzed rooster testes to find out.. Chickens acquire and harbor a wide variety of viruses. When a virus infects a host, like a chicken, it does everything it can to survive. One method of survival is inserting its genetic material into the chickens genome. Over generations, the inserted virus accumulates mutations and eventually becomes harmless to the animal, but its still a part of the chickens genetic material.. Lis team focused on avian leukosis virus, which commonly infects and can lead to cancer in domestic chickens. Through molecular and genetic analysis, they discovered that chickens turn these old, existing viruses into piRNA-producing machines. When faced with a new avian leucosis virus (there are many different viruses in the family), the old viruses pump out piRNAs that defend the germ cells, ensuring the ...

Previous reports have shown that spleen cells from nonimmune adult mice of certain strains do regularly kill Moloney leukemia virus-induced lymphomas in short-term 51Cr release assays. This naturally occuring killer (NK) cell had low adherent properties and had the morphological appearance of a lymphocyte. Still it lacked surface characteristics of mature T or B lymphocytes. In the present report a functional study was carried out, comparing in parallel the NK system, the T-cell killing across an H-2 barrier (anti-P815), and the antibody-dependent cell-mediated chicken red blood cell (CRBC) system. In contrast to the effector cells in the CRBC system, the NK cells were insensitive to erythrocyte antibody complement (EAC) rosette depletion and would pass through nylon wool columns. NK activity was not inhibited by the presence of heat-aggregated human or mouse gamma globulin, in contrast to the strong inhibition noted in the CRBC system.
