EBI3 and Burkitt lymphoma: Analysis of the GSE447 and GSE4732 microarray datasets that we previously analyzed for EBI3 expression (27) and totalized 98 cases of Burkitt lymphoma and 344 cases of DLCLC defined by molecular gene profiling, showed that not only EBI3 but also p35 levels were significantly upregulated in DLBCL compared to Burkitt lymphoma (Figures 1A,B).
