RESUMO

Abstract:Subgroup J avian leukosis virus (ALV-J) infect cells by binding to the chNHE1 receptor protein of the host and causes tumors. The tumor incidence of the ALV-J-infected chickens was observed by histo pathology, and virus was isolated on DF-1 cell line. The ALV-J load and mRNA of chNHElreceptor protein were detected by real time PCR. The relationship between ALV-J load, chNHE1 receptor expression levels and tumor spectrum was analyzed. The results showed that the tumors induced by ALV-J in laying hens and local lines of chicken were different. No significant relationship was observed between ALV-J load and tumor spectrum. ALV-J load was positively correlated with mRNA expression of chNHE1. The mRNA expression of chNHE1 increased when the tumors occurred. Our results suggest the chNHE1 protein is not only the receptor of ALV-J infected host but also play an important role in the process of tumor development. This study provides a scientific basis for further studying of oncogenic mechanism of ALV-J.
