Technical Abstract: Marek’s disease (MD) is a lymphoproliferative disease in chicken caused by oncogenic Marek’s disease virus (MDV). MD is characterized by infiltration of proliferating lymphoid cells in organs, such as peripheral nerve, skin, muscle, liver, spleen, heart, kidney, gonads and proventriculus. Epigenetic modifications such DNA methylation, histone modification and some non-coding RNAs are mitotically or meiotically heritable gene expression changes that do alter the underlying DNA sequences. Epigenetic factors are believed to play important roles in tumorigenesis in mammals with increasing evidence for viruses as environmental agents especially in humans. The goal of our research is to explore the histone modification profiles induced by MDV in two chicken lines that are relatively resistant (Line 63) or highly susceptible (Line 72) to MD. We hope to identify changes of specific histone modifications that differentiate the two chicken lines for MD resistance. These changes may provide clues that lead to the identification of causal genes or pathways responsible for genetic resistance to tumorigenesis.
