Myeloid Leukosis (J-virus) - An International Broiler Industry Concern

open access: yesEDIS, 2003
Myeloid leukosis (ML) or myelocytomatosis/myeloblastosis is caused by a retrovirus in the Avian Leukosis/Sarcoma Group of Retroviruses (ALV). This ALV subgroup J virus (ALV-J), which is identified as the etiologic agent for ML, has caused substantial ...

A Genetically Engineered Commercial Chicken Line Is Resistant to Highly Pathogenic Avian Leukosis Virus Subgroup J

open access: yesMicroorganisms, 2021
Viral diseases remain a major concern for animal health and global food production in modern agriculture. In chickens, avian leukosis virus subgroup J (ALV-J) represents an important pathogen that causes severe economic loss.

gga-miR-375 plays a key role in tumorigenesis post subgroup J avian leukosis virus infection.

open access: yesPLoS ONE, 2014
Avian leukosis is a neoplastic disease caused in part by subgroup J avian leukosis virus J (ALV-J). Micro ribonucleic acids (miRNAs) play pivotal oncogenic and tumour-suppressor roles in tumour development and progression.

Precise CRISPR/Cas9 editing of the NHE1 gene renders chickens resistant to the J subgroup of avian leukosis virus

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance The current progress of genome editing techniques accelerates the knock-out and knock-in studies in animal models and production of genetic modifications in livestock. Increased resistance to viral pathogens is a particular goal because many

Cell killing by avian leukosis viruses [PDF]

open access: yesJournal of Virology, 1981
Infection of chicken cells with a cytopathic avian leukosis virus resulted in the detachment of killed cells from the culture dish. The detached, dead cells contained more unintegrated viral DNA than the attached cells. These results confirm the hypothesis that cell killing after infection with a cytopathic avian leukosis virus is associated with ...
