Integration of Host and Virus Gene Expression for Chickens Response to Avian Leukosis Virus Challenge

The tumorigenesis caused by avian leukosis virus (ALV) occurs through a complex regulatory architecture. , We applied a novel methodology to jointly analyze four different types of datasets: mRNA expression, the associated regulatory factors of miRNA and lncRNA, and ALV gene expression. The pathway analysis shows that combined analysis produced more informative results than single data-type analyses, and the co-expression network analysis found key elements involved in the host-pathogen interaction. The integration of multiple data sources yielded deeper insights into the pathogenesis of the virus and the host immune response.
