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

PLoS 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.

Cell killing by avian leukosis viruses [PDF]

Journal 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 ...

Co-infection with avian hepatitis E virus and avian leukosis virus subgroup J as the cause of an outbreak of hepatitis and liver hemorrhagic syndromes in a brown layer chicken flock in China

Poultry Science, 2020
Hens of a commercial Hy-line brown layer flock in China exhibited increased mortality and decreased egg production at 47 wk of age. From 47 to 57 wk, average weekly mortality increased from 0.11 to 3.0%, and egg production decreased from 10 to 30%, with ...

Single and concurrent avian leukosis virus infections with avian leukosis virus-J and avian leukosis virus-A in Australian meat-type chickens [PDF]

Avian Pathology, 2005
Australian broiler breeders were screened for avian leukosis viruses (ALVs) (May 2001 to December 2003) as surveillance of measures to reduce the prevalence of ALV-J. Samples of blood (4233), albumen (1122), meconium (99) and tumours (16) were obtained from 93 flocks in six Australian states. Virus isolation was performed in C/O chick embryo fibroblast
