Report on Avian Leukosis Conference

Poultry Science, 1966
Abstract A Technical Workshop Conference on Diseases of the Avian Leukosis Complex was held at the University of Georgia, October 12–13, 1965. Participation was restricted to individuals currently engaged in research on avian leukosis. Forty-six papers, dealing with all research approaches to the problem of avian leukosis, were presented. In addition,

Comparison of the RNA-Dependent DNA Polymerase of an Endogenous Avian Leukosis Virus to the Polymerase of an Exogenous Avian Leukosis Virus [PDF]

European Journal of Biochemistry, 1978
RNA-dependent DNA polymerases from Rous-associated virus-O and avian myeloblastosis virus were partially purified by affinity chromatography and compared to each other. The enzymes are indistinguishable in the immunoglobulin inhibition test and by several enzymological criteria, such as optimum curves for the concentrations of Mg2+, K+, H+; monophasic ...

MiR-125b Suppression Inhibits Apoptosis and Negatively Regulates Sema4D in Avian Leukosis Virus-Transformed Cells

Viruses, 2019
Subgroup J avian leukosis virus (ALV-J), an oncogenic retrovirus, causes hemangiomas and myeloid tumors in chickens. We previously showed that miR-125b is down-regulated in ALV-J-induced tumors.

A 19-nucleotide insertion in the leader sequence of avian leukosis virus subgroup J contributes to its replication in vitro but is not related to its pathogenicity in vivo. [PDF]

PLoS ONE, 2014
Subgroup J avian leukosis virus (ALV-J) was first isolated from meat-type chickens that had developed myeloid leukosis and since 2008, ALV-J infections in chickens have become widespread in China.

Ectopic expression of the erythrocyte band 3 anion exchange protein, using a new avian retrovirus vector [PDF]

, 1990
12 pages, 5 figures, 3 tables.A retrovirus vector was constructed from the genome of avian erythroblastosis virus ES4. The v-erbA sequences of avian erythroblastosis virus were replaced by those coding for neomycin phosphotransferase, creating a gag-neo ...

Differentially expressed genes in a flock of Chinese local-breed chickens infected with a subgroup J avian leukosis virus using suppression subtractive hybridization [PDF]

, 2010
Avian leukosis virus subgroup J (ALV-J) is a new type of virus that mainly induces myeloid leukosis (ML) in chickens. To further elucidate the pathogenesis of ALV-J infection and tumor development, expression profiles from the bone marrow tissue of 15 ...

Virus or Avian Myeloblastic Leukosis

Poultry Science, 1956
Abstract INTRODUCTION AVIAN leukosis is a complex of diseases which are not only of much economic importance, but which, in addition, comprise one category of virus-induced tumors. As a consequence, knowledge of the diseases is of fundamental interest in its bearing on the problem of cancer as a whole. Since the initial reports of the viral etiology

Marek\u27s Disease - Leukosis [PDF]

, 1969
During the past few years there have been many significant new findings concerning the avian leukosis complex. Until recently these diseases were termed visceral leukosis, neural leukosis, or avian lymphomatosis.

Immunological phenotype of lymphomas induced by avian leukosis viruses. [PDF]

Molecular and Cellular Biology, 1983
The production of immunoglobulin by six cell lines derived from bursal tumors induced by avian leukosis virus follows two general patterns: (i) three cell lines that have been extensively passaged in culture synthesize and secrete light chains only; (ii) three cell lines that are recently isolated produce and secrete monomeric immunoglobulin M in ...

Naturally Occurring Co-infection of Avian Leukosis Virus (subgroups A-E) and Reticuloendotheliosis Virus in Green Peafowls (Pavo muticus)

Brazilian Journal of Poultry Science
Most of the neoplastic diseases affecting poultry have a viral etiology, such as Marek’s disease, avian leukosis/sarcoma and reticuloendotheliosis. In the present paper, histopathology and molecular methods were performed, in addition of necropsy and ...
