Objective:
1. Identify MDV Meq and c-Jun binding sites in the chicken genome. 2. Identify differentially expressed genes following MDV-reactivation in MSB-1 cells. 3. Determine if differentially expressed genes identified in objective 2 also show differentially expression between MD tumors and CD4+ T cells. 4. Identify differentially expressed genes as a function of genetic resistance status or the presence of Meq.

Approach:
1. Utilize chromatin immunoprecipitation (ChIP) using Meq or c-Jun antibodies and determine the DNA sequences via Solexa paired-end reads. 2. Isolate RNA from MSB-1 cells at time 0 and following MDV reactivation, and run on Affymetrix Chicken microarrays. 3. Compare by qRT-PCR the relative expression of key genes between MD tumors and CD4+ T cells. 4. Isolate RNA from line 6 (MD resistant) and line 7 (MD susceptible) CEF at various time before and after infection with either MDV or MDV lacking Meq, and run on Affymetrix Chicken microarrays.
